Background/Objective: Early periodontitis diagnosis is challenging due to varying staging and grading systems. While clinical parameters like bleeding on probing (BoP) and pocket depth (PD) are commonly used, periapical radiographs provide valuable information about bone loss and periodontal ligament changes. However, a clear definition of early periodontitis, particularly regarding alveolar bone crest changes, remains elusive. Methods: This cross-sectional study involved 21 participants aged 20–30 with clinical signs of periodontitis and radiographic evidence of alveolar bone changes and periodontal ligament widening. Four dentists assessed 40 cases for BoP, 40 for PD, and 40 for periapical radiographs. Results: Statistical analysis revealed that the pocket depth measurement was the most significant factor in diagnosing early periodontitis (Fisher’s exact test, p-value = 0.000). Additionally, the irregularity of the alveolar crest proved to be a significant marker compared to periodontal ligament width (Fisher’s exact test, p-value = 0.000). A Kendall Tau_b test (p-value = 0.000, r = 1.000) confirmed pocket depth to be the most influential parameter among the assessed factors. Conclusions: While this study highlights the importance of clinical and radiographic assessments in early periodontitis detection, integrating these findings into a definitive diagnosis can be complex. The standardization of diagnostic techniques and the development of advanced radiographic interpretation methods are crucial to improve accuracy. Further research is needed to refine diagnostic criteria and explore additional tests for early periodontitis detection. Full article

Background: Oral and implant surgery represent highly specialized fields within dentistry that require a deep understanding of complex anatomical structures, together with practical hands-on experience. The present review examines common trends in oral and implant surgery training, focusing on how traditional methods like donated body dissection coexist with different and modern educational tools, and highlights the pros and cons of the different approaches in order to optimize training outcomes. Methods: A systematic literature search was carried out using the databases PubMed and Cochrane Library including the last 10 years of published articles about training in oral surgery and implantology. Starting from a total of 1319 studies, 47 were included to be carefully evaluated, and 20 studies were finally selected for this narrative review. The studies utilize methodologies such as randomized controlled trials (RCTs), cross-sectional surveys, case–control studies, and systematic reviews. The results were thematically organized, highlighting key quantitative outcomes and drawing connections between the different educational approaches. Results: From the narrative review, it emerged that oral and implant surgery training requires a careful balance between traditional methods, such as donated human body dissection, and modern technological advancements like virtual simulations and synthetic models. While animal and synthetic models have specific uses, their application remains limited in replicating the full complexity of human anatomy. These last technologies offer flexibility and expanded access to education but do not substitute for the hands-on experience gained through donated human body dissection. Conclusions: As educational institutions continue to evolve their training programs, ensuring access to human body dissection remains of paramount importance. Combining the strengths of both traditional and modern approaches may help optimize oral and implant surgery education, enhancing student preparedness without overlooking the critical value of direct anatomical experience.

Background/Objectives: This systematic review aimed to compare the tunnel technique for pre-implant bone regeneration with traditional flap techniques also involving a crestal incision, in terms of procedure success, graft healing, postoperative course, patient satisfaction, and implant follow-up. Methods: A systematic search was conducted on MEDLINE/PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials following PRISMA guidelines, searching for comparative prospective and retrospective studies in English, published between January 2002 and April 2024. The population of interest consisted of patients with edentulous ridge atrophy requiring pre-implant bone regeneration. The primary outcome was the success of the procedure. The secondary outcomes included complications, patient comfort, graft resorption, bone gain, primary implant stability, implant success/survival, peri-implant bone level change, and operative time. The risk of bias was assessed using RoB2 and ROBINS-I. Results: The search and selection process yielded one randomized controlled trial and three comparative observational studies, all with serious/high risk of bias. A narrative synthesis was conducted due to the small number of studies and the heterogeneity in key features. The tunnel technique might provide some advantages in terms of the success of the procedure, but the findings were not statistically significant. Conflicting findings or non-significant differences were reported in terms of the secondary outcomes. Conclusions: This review suggested some potential advantages of the tunnel technique for bone augmentation over traditional techniques involving a crestal incision, but the limited quality and amount of data precluded any definitive conclusions.

Background/Objectives: Electronic cigarettes (e-cigarettes) are commonly used by former smokers as an alternative product to conventional cigarettes and also by young adults and adolescents to deliver nicotine. E-cigarettes are thought to be a less harmful and more socially acceptable alternative to tobacco smoking; however, their long-term effects on health, including oral health, are currently unknown. Methods: A literature search for relevant papers indexed in the literature from 2016 to 2023 was conducted using the PubMed, Scopus, and Google Scholar databases. In our paper, we included clinical trials and both in vivo and in vitro research concerning the impact of e-cigarettes on oral health. Results: E-cigarettes impact the oral cavity, which is directly exposed to inhaled chemicals present in e-cigarette aerosols. The use of e-cigarettes has been linked to teeth discoloration and dental caries, promoting the development of periodontal diseases and causing oral mucosa lesions, including oral cancer. E-cigarette aerosols might also negatively affect the oral microbiome by suppressing the growth of commensal bacteria and increasing the population of bacteria responsible for developing numerous oral disorders. E-cigarettes also impact saliva composition and its properties, including reducing saliva’s antibacterial and antioxidant properties, which may subsequently lead to the promotion of oral diseases. Conclusions: The outcomes suggest that e-cigarette usage may cause the development of oral diseases, however further longitudinal studies of a larger and homogenous group of e-cigarette users are required.

Background/Objectives: The etiology of diffuse gingival enlargement is multifactorial, and the definitive diagnosis may be challenging. To highlight the nuances of the differential diagnosis, we present two cases of generalized gingival overgrowth and discuss the diagnostic dilemmas. Case description: In the first case, an 82-year-old male with a medical history of hypertension and prostatitis had a chief complaint of symptomatic oral lesions of a 20-day duration, accompanied by fever and loss of appetite. The clinical examination revealed diffusely enlarged, hemorrhagic, and focally ulcerative upper and lower gingiva, ecchymoses on the buccal mucosa, as well as bilateral cervical lymphadenitis. The histopathologic and immunohistochemical findings combined with the hematologic examination led to a final diagnosis of acute myeloid leukemia, and the patient was referred to a specialized hematology/oncology unit for further management. The second case was a 74-year-old female with a medical history of breast cancer (successfully managed in the past), type II diabetes mellitus, and cardiovascular disease, taking various medications. An intraoral examination revealed diffusely enlarged, erythematous, and hemorrhagic upper and lower gingiva. An incisional biopsy showed hyperplastic granulation and fibrous connective tissue with a predominantly chronic inflammatory infiltrate. Considering the patient’s medical history and current medications, the clinical and microscopic findings were in support of the diagnosis of drug-induced gingival overgrowth associated with calcium channel blocker (amlodipine), partially controlled diabetes serving as an additional predisposing factor. Gingivectomy and periodontal scaling, along with substitution of the offending medication, were curative, and better diabetic control was recommended. Conclusions: Diffuse gingival overgrowth may be caused by a variety of diverse conditions, ranging from an exuberant response to local factors, potentially exacerbated by hormonal influences (e.g., puberty or pregnancy), to drug side effects to genetic, systemic, or even neoplastic diseases. A careful evaluation of the medical and drug history and clinicopathologic correlation is essential for accurate diagnosis and appropriate management. Full article

Background/Objectives: This study aims to compare the effects of conventional surgical techniques and laser-assisted methods on salivary oxidative stress biomarkers following third molar extraction, in order to evaluate the potential benefits of laser surgery in reducing oxidative stress and promoting faster recovery. Methods: A total of 154 patients, aged 16–30, undergoing third molar extractions were included in the study. Patients were divided into two groups: conventional surgery (n = 75) and laser-assisted surgery (n = 79). Saliva samples were collected at baseline, and 24, 48, 72, and 168 h postoperatively. The levels of total antioxidant capacity (TAC), malondialdehyde (MDA), and 8-hydroxy-2′-deoxyguanosine (8-OHdG) were measured as indicators of oxidative stress. Results: Initial biomarker levels were similar across all participants. Postoperative oxidative stress increased in both groups, with significantly higher levels in the conventional surgery group at 48 and 72 h. Salivary biomarkers of oxidative stress were significantly lower in the laser group at 48 and 72 h post-surgery (p < 0.05), indicating a faster recovery. By 168 h, biomarker levels in the laser group had nearly returned to baseline, whereas levels in the conventional group remained slightly elevated. Conclusions: Laser-assisted surgery significantly reduces oxidative stress and promotes faster recovery when compared with conventional methods, as evidenced by the more rapid normalization of salivary biomarkers. These findings suggest that laser techniques may offer superior clinical outcomes in third molar extractions. Full article

Background/Objectives: Dental emergencies significantly impact public oral health, particularly in the post-COVID-19 context. This study aimed to analyze the patterns of dental emergencies presenting to the Emergency Dental Service in Bihor, Romania, during the years 2022 and 2023, focusing on demographic characteristics and the frequency of diagnoses. Methods: A retrospective analysis of medical records from the Emergency Dental Service at Oradea County Emergency Clinical Hospital was conducted. Inclusion criteria encompassed patients presenting with dental emergencies during the specified period. Data regarding demographics, diagnoses, and living environments were collected and statistically analyzed. Results: A total of 4769 patients were analyzed, with acute pulpitis (39.2%, n = 1869) and acute apical periodontitis (37.5%, n = 1788) identified as the most common diagnoses. The study population included 52.3% males and 47.7% females, with a larger proportion residing in urban areas (58.0%) compared with rural areas (42.0%). Significant age-related patterns were evident: pulpitis was more common among patients aged 10–39 years, trauma was associated with patients aged 0–9 years, and gingival infections were prevalent in the 70–79 age group. Diagnoses also varied by dentition type, with abscesses, caries, trauma, and rhizolysis occurring more frequently in deciduous teeth, while pulpitis and post-extraction alveolitis were predominant in permanent teeth. However, no statistically significant differences were found in diagnosis frequency between genders or between rural and urban patients, indicating equitable access to emergency services across environments. Conclusions: The findings underscore the need for targeted interventions in pediatric populations to address early childhood caries, which remains a significant burden. Enhanced public health strategies and preventive education are essential to mitigate the prevalence of dental emergencies, particularly in the aftermath of the COVID-19 pandemic. Full article

Background/Objectives: Dental malocclusions are highly prevalent worldwide, negatively impacting patients’ quality of life and leading to complex, often costly, orthodontic treatments. In Romania, the economic status of patients and the limited public funding for orthodontic care significantly influence treatment accessibility and choices. Advanced technologies, such as mini-implants (MIs), offer improved anchorage and treatment efficiency but are often underutilized due to financial constraints and variability in clinical training. In this context, there are limited data regarding the use and preferences of MI among orthodontists in Romania. This study aims to explore the characteristics, preferences, and challenges of Romanian orthodontists in their use of MI systems. Methods: A survey was conducted between June and September 2024, targeting orthodontists across Romania. The questionnaire, distributed via social media platforms, consisted of 24 items addressing professional experience, MI system preferences, insertion methods, and complications. Statistical analyses were conducted using IBM SPSS Statistics 25. Fisher’s Exact Test and Pearson’s Chi-Square Test were employed to evaluate relationships between categorical variables. When appropriate, logistic binomial univariable regression models were applied to predict key dependent variables (e.g., MI placement zones, MI experience, and MI complications) based on independent variables such as specific MI system usage and frequency of MI usage. A significance threshold of α = 0.05 was used for all tests. Results: Out of 105 participants, 85.7% reported using mini-implants (MIs) in their orthodontic practice, with the Dual Top and Benefit systems being the most frequently used (60% and 43.3%, respectively). The interradicular area was the most common placement site (60%), while the palatal and retromolar regions showed significant correlations with the Benefit system (p = 0.008). Practitioners with more than 10 years of experience reported a significantly higher frequency of MI use (p = 0.001), with frequent use being observed in 60.9% of these practitioners. Complications were common, with MI mobility reported by 92.2% and soft tissue damage by 57.8%. The midpalatal area was significantly associated with higher complication rates compared to other sites (p < 0.001). The success rates of MI usage ranged from 76% to 100% in 57.8% of respondents, with higher success rates being associated with infrazygomatic placements (p < 0.05). Conclusions: MI usage is prevalent among Romanian orthodontists, with experienced practitioners utilizing them more frequently. Despite high success rates, common complications highlight the need for improved insertion techniques and post-operative care. Further research and training are recommended to optimize MI application and reduce complication rates. Full article

Background: Traditional methods for palatal expansion using fixed appliances often face limitations in comfort and aesthetics. In comparison, aligner therapy has limitations, particularly regarding maxillary expansion. The aim of this study is to examine the biomechanical properties regarding the wire diameter and bending of different stainless steel wires to evaluate their potential for incorporation into maxillary aligner therapy. Materials and Methods: Three rectangular stainless steel wires (0.016″ × 0.022″, 0.017″ × 0.025″, and 0.019″ × 0.025″) were tested for mechanical expansion forces in the intermolar region, comparing non-tooth-shaped bent wires (A groups) and tooth-shaped bent wires (B groups). Using a Z010 testing machine (ZwickRoell GmbH and Co. KG, Ulm, Germany), expansion forces were measured at 1 mm intervals over a 5 mm distance, with 15 samples analyzed per group. Statistical analyses included the Shapiro–Wilk test for normal distribution, the Mann–Whitney U test, which revealed significant results (U = 225, p < 0.001), and the Kruskal–Wallis test, which indicated significance (H = 39.130; df = 2; p < 0.001). Results: Tooth-shaped bent wires exhibited significantly lower expansion forces than non-tooth-shaped bent wires for all tested wire types. This difference was most notable in wires with larger transverse profiles (0.019″ × 0.025″), where the tooth-shaped bent wires displayed a marked reduction in mechanical load capacity. Specific force measurements for non-tooth-shaped wires ranged from 760.61 ± 79.51 mN at 1 mm of deformation to 2468.46 ± 66.27 mN at 5 mm of deformation, while tooth-shaped wires ranged from 116.80 ± 3.74 mN to 1979.49 ± 23.23 mN. Conclusions: These findings suggest that non-tooth-shaped bent wires offer a more efficient and uniform expansion potential for maxillary movements due to their stable elastic properties. Clinically, integrating non-tooth-shaped stainless steel wires into aligner therapy may provide a viable method for maxillary expansion, supporting both first- and second-order movements in orthodontic treatment. Further research is needed to explore the integration of such wires for effective maxillary expansion in aligner therapy. Full article

Objectives: We evaluated associations between changes in dental anxiety and oral health-related quality of life (OHRQoL) in parents of the FinnBrain Birth Cohort Study. Methods: Two-year dental anxiety trajectories measured with Modified Dental Anxiety Scale from gestational weeks (gw) 14 and 34, and 3 and 24 months after birth were used. OHRQoL was measured with the Oral Health Impact Profile 14-item questionnaire at gw34 and 4 years. Changes in the OHRQoL sum and dimension scores according to dental anxiety trajectories were analyzed with the Jonckheere–Terpstra test separately for mothers (n = 998) and fathers (n = 513). Results: Overall, OHRQoL decreased in all dental anxiety trajectory groups except the High decreasing group in mothers, and in the Stable high group in fathers. The decline in the overall OHRQoL was greatest in the Stable high trajectory group for both parents. In fathers, OHRQoL increased considerably but not statistically significantly in the High decreasing trajectory group. The changes in OHRQoL dimensions Psychological discomfort and Handicap differed according to dental anxiety trajectories for both of mothers and fathers, and also for the dimension Psychological disability for mothers. Conclusions: These findings highlight the need for targeted interventions in treating high dental anxiety and in preventing the increase in dental anxiety to improve oral health outcomes such as OHRQoL.

Background: Adhesion within endodontic obturation material and root canal walls improves the efficacy of the endodontic treatment by establishing a barrier that inhibits reinfection and entombs residual bacteria. This study evaluates the push-out bond strength (POBS) of calcium silicate sealers compared to an epoxy-resin-based sealer. Methods: A total of 36 extracted mono-radicular teeth were prepared with Pro Taper Ultimate and irrigated with 5.25% sodium hypochlorite and 17% EDTA. The specimens were randomly split into three groups (n = 12) according to the endodontic sealer and filling technique used as follows: Ah Plus with the continuous wave condensation technique (CWC), Ah Bioceramic (Ah Bio) with the single-cone technique, and Total Fill Hi-Flow (FKG Hi-Flow) with the CWC technique. The material was allowed to set for 4 weeks, and afterwards, the roots were placed in acrylic resin and sectioned into 1 mm transverse slices. A POBS test was conducted using a universal testing machine, and the mode of bond failure was assessed at 4× magnification using a stereomicroscope. Six specimens from each group were selected for SEM-EDX examination to evaluate dentinal tubule penetration. The data were analysed using analysis of variance and Tukey and Bonferroni post hoc tests. Results: The POBS tests revealed higher values for Ah Plus in comparison to both calcium silicate sealers (p < 0.001), while FKG Hi-Flow showed superior results to Ah Bio (p < 0.001). The cohesive mode of failure was prevalent in all three groups. Conclusions: In conclusion, the resin-based sealer showed higher bond strength and better dentinal tubule penetration than the two calcium silicate sealers tested, while FKG Hi-Flow outperformed AH Bio.

Objectives: Our study aimed to establish the basic reliability parameters of direct immunofluorescence test results in patients with oral lichen planus. Methods: We conducted an evaluation of individual antibody classes in the DIF and ELISA (BP180 antigen), comparing these results with the classical histopathological (HP) examination in a group of patients treated within the standard healthcare in our clinic. Results: Among 66 participants with oral changes indicative of LP, only 50% received histopathological confirmation of the LP diagnosis. Among those with a DIF profile entirely typical for LP (C3+, F+), 57.1% had a positive HP result. Fibrinogen deposits were identified in 42.4% and 36.4% of individuals with positive HP results for F1 and F2, respectively; 78.8% of patients with negative HP and 57.6% with positive HP exhibited no fibrinogen deposits. Simultaneous positivity for F1 and F2 occurred in all cases where F1 was positive. HP confirmed positive DIF for C3 in 50% of cases. Fibrinogen deposits demonstrated the highest diagnostic accuracy (61%). Sensitivity and specificity for fibrinogen deposits were 36% and 42% for F1 and 79% and 82% for F2. The positive predictive values were 67% for F1 and 67% for F2, while the negative predictive values were 58% for F1 and 56% for F2. Overall diagnostic accuracy was reported at 61% for F1 and 59% for F2. Conclusions: Our data indicate the complementarity of HP and immunological test results and the necessity of using both methods together in cases of doubt. Full article

Background/Objectives: The aim was to evaluate the agreement between plaque detection with an intraoral scanner system (IOS) and a conventional clinical method and to evaluate the inter-rater reliability for scoring 3D models with and without a disclosing agent. Methods: A total of 14 participants were recruited from the Department of Operative Dentistry, School of Dentistry, National and Kapodistrian University of Athens. Participants eligible for inclusion were adults with good general health and a minimum of 20 teeth. Participants were clinically examined with plaque assessment according to the modified Quigley–Hein plaque index before and after using a disclosing agent (GC-Tri Plaque ID-Gel, GC, Europe N.V). Before and after the application of the disclosing agent, all study participants were scanned using the IOS (TRIOS5, 3Shape TRIOS A/S). The clinical examiner and three additional examiners blinded to the clinical examination assessed plaque status on the acquired 3D models with and without disclosing agent using the same index to evaluate the inter-rater agreement. Intraclass coefficient correlation, one sample t-test, and Cronbach’s α for inter-rater reliability were calculated. Results: All methods showed moderate to strong correlations (Spearman’s rho ranging from 0.527 to 0.618), and Cronbach’s α ranged from 0.551 to 0.766. Conclusions: The level of agreement between conventional clinical registration and registration from 3D models was acceptable overall. Full article

Background: This study aimed to develop an algorithm for modelling tooth–tooth or implant–implant support configurations for a given 4-unit fixed partial denture (FPD). Methods: The algorithm was implemented in Rhinoceros/Grasshopper to automatically generate geometries with varying bone loss (0 mm to 3 mm), support type (tooth–tooth and implant–implant support) and bone quality (D1 to D4) for a 4-unit FPD. Afterward, a finite element analysis was carried out with a load applied to the central connector of the FPD. Stresses in the FPD and the bone around the support were analysed. Results: The results indicated that stresses in the bone were influenced by both the depth of bone loss and bone quality across both support types. The maximum stress in the tested FPD models for tooth–tooth support was not significantly influenced by bone quality; instead, the stress peaks were primarily influenced by the depth of bone loss. For D1 bone, the stresses in FPD and bone increased by 4.79% and 8.86%, respectively, for tooth–tooth support and about 32.67% and 100.96%, respectively, for implant–implant support. Conclusions: The proposed algorithm allows for the automatic, parametrised generation of support for 4-unit fixed partial dentures, which can be used to predict the effect of bone loss and bone quality on stresses for patient-specific geometries. The optimal treatment for support type should be adapted to the patient’s specific needs to ensure long-term stability. A decision support involving automatic modelling, e.g., of support, and simulation might improve clinical treatment planning from a long-term perspective. Full article

Background: Comparing the effectiveness of virtual and traditional learning methods is crucial for understanding their impact on knowledge transmission in different subjects. The objective of this cross-sectional study was to explore dental students’ perceptions and satisfaction levels with their experiences in virtual learning compared to traditional classroom learning. Methods: A cross-sectional survey was administered to all dental students in the College of Dentistry across preclinical (3rd and 4th year) and clinical (5th and 6th year) levels using Google Forms. The questionnaire included items from the validated student survey component of the Blended Learning Toolkit, the Quality Matters Higher Education Rubric, and the Web Learning Project Student Survey. Results: With a 93% response rate from 313 students, the survey results indicated a strong preference (87%) for traditional learning among 3rd-year preclinical students who favored it over virtual learning, contrasting with 54% of 6th-year clinical year students. Most of the students acknowledged that traditional learning facilitates the use of various instructional methods while virtual learning hinders interactions among each other (p = 0.068). However, virtual lectures were perceived as more organized (70% to 89%, p = 0.014). Gender differences were minimal in preference for virtual learning, but male students significantly preferred traditional methods (p = 0.001). Conclusion: The results indicate a preference for traditional over virtual learning, especially among males and preclinical dental students, emphasizing the need for an integrated approach that combines the structured benefits of virtual learning with the interactive advantages of traditional classrooms.

Background: Sterilization is required for any biomedical device intended to be used in contact with the human body. Several studies have reported alterations in the bulk and surface properties of such devices after repeated sterilization cycles. These surface modifications may influence other clinical parameters. Therefore, the aim of this study was to investigate the surface and chemical properties of implant scan bodies (SBs) after consecutive autoclave sterilization procedures. Methods: The objective was to analyze the scan bodies using Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) for chemical analysis and an optical profilometer to analyze the surface roughness. Results: FTIR spectra depicted the appearance of peak at 1741 and 1100 cm⁻¹ due to the diphenyl ether band disappearance. The XPS spectra showed alterations in the elemental composition after autoclaving and roughness were significantly reduced in PEEK BL and TL SBs. Conclusions: These results indicated that some surface modifications were induced by repeated sterilization cycles. Full article

Background: Oral diseases remain among the most common non-communicable diseases worldwide, affecting almost half of the world’s population. This is partly because there has been a separation of the mouth from the rest of the body and human health, and psychological aspects such as personality, thoughts, and emotions are not taken into account in the dental office. The objective was to analyze the relationship between oral health conditions and personality traits in adult patients who underwent dental treatment at the Center for Health Studies and Services. Methods: This was a descriptive, observational, and correlational study, carried out at the Center for Health Studies and Services. A total of 184 patients who attended the dentistry area in the period from October 2022 to May 2023 participated in the study, of which 59.78% were women and 40.21% men. The age of the population was 18 to 79 years, with the age range of 21–40 years being the most prevalent (48.37%). Results: The results show that although the hygiene of the population treated was good (0.77 ± 0.79) and that the perception of oral health was positive (14.34 ± 9.43), the means and percentages of oral pathologies and parafunctional habits were high (i.e., DMFT: 9.98 ± 5.40; attrition: 87.50%; onychophagia: 45.10%). It is noteworthy that both the correlation, network, multiple line regression, and logistic regression analyses showed associations of the personality, gender, and age variables with a history of caries and oral hygiene as well as with parafunctional habits. Conclusions: Therefore, variations in both the personality and the age and gender of the patients treated have repercussions on oral health conditions, which can be used in the prevention of oral diseases and in health promotion.

Background: Little has been written in the literature about the clinical comparison between the single use of chlorhexidine (CHX) and its combination with cetylpyridinium chloride (CPC). The purpose of this study is to compare the clinical effectiveness of two at-home antiseptic regimens. Methods: Healthy subjects scheduled for dental surgery were enrolled. After the surgery, patients were randomly allocated to the first group (group A), which received a manual ultrasoft toothbrush (Mentadent Professional^®), an antiseptic toothpaste with 0.12% CHX and Vitamin B3 (Mentadent Professional Azione Intensiva Gengive^®), and an antiseptic mouthwash with 0.12% CHX and 0.07% CPC. The second group (group B) solely received an antiseptic mouthwash with 0.2% CHX in conjunction with an anti-discoloration system (Curasept ADS/DNA^®) and were encouraged to use their usual toothbrush and toothpaste. Patients were instructed to use the products twice a day and to rinse for 30 s. On day 7, patients were examined for the early healing score (EHS), visual plaque index (VPI) of the sutures, numerical rating scale (NRS), and mouthwash taste. Results: Group A showed a statistically significant level of EHS and taste satisfaction. VPI and NRS were different but not significant among the studied groups. Conclusions: The regimen based on CHX used in conjunction with vitamin B3 in the toothpaste and CPC in the mouthwash resulted in superior clinical outcomes and satisfaction compared to CHX alone.
