Background: Autism spectrum disorder (ASD) represents a neurobiological disorder with a high prevalence in the children’s population. The aim of the present review was to assess the current evidence on the use of salivary biomarkers for the early diagnosis of ASD. Materials and methods: A search was conducted on the electronic databases PUBMED/Medline, Google Scholar and Scopus for the retrieval of articles concerning the study topic. Results: A total of 22 studies have been included in the present review considering 21 articles identified from databases and 1 article included using a manual search. A wide range of biomarkers have been proposed for early detection of ASD diseases including nonspecific inflammation markers like interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor α (TNFα), oxidative stress markers like superoxide dismutase and glutathione peroxidase, hormones such as cortisol and oxytocin, various microRNAs including miR-21, miR-132 and miR-137, and exosomes. The techniques used for biomarke detection may vary according to molecule type and concentration. Conclusions: salivary biomarkers could represent a potential useful tool for the primary detection of several systemic diseases including ASD, taking advantage of non-invasiveness and cost-effective capability compared to other biofluid-based diagnostic techniques.

Background: Obstructive sleep apnea (OSA) is a prevalent disorder in both pediatric and adult populations, characterized by substantial morbidity encompassing cardiovascular, neurocognitive, and metabolic impairments. Management strategies vary by age group and underlying etiology, with orthodontic and non-orthodontic interventions playing key roles. This narrative review synthesizes the current evidence on orthodontic and non-orthodontic therapies for OSA in pediatric and adult populations, emphasizing individualized, multidisciplinary care approaches and highlighting future research directions. Methods: A narrative review was conducted using PubMed, Scopus, and Google Scholar to identify studies on diagnosis and management of OSA in children and adults from 2000 to 2025. Results: In pediatric patients, treatments such as rapid maxillary expansion (RME), mandibular advancement devices (MADs), and adenotonsillectomy have shown promising outcomes in improving airway dimensions and reducing apnea–hypopnea index (AHI). For adults, comprehensive management includes positive airway pressure (PAP) therapy, oral appliances, maxillomandibular advancement (MMA) surgery, and emerging modalities such as hypoglossal nerve stimulation. Special attention is given to long-term treatment outcomes, adherence challenges, and multidisciplinary approaches. Conclusions: The findings highlight the need for individualized therapy based on anatomical, functional, and compliance-related factors. As the understanding of OSA pathophysiology evolves, orthodontic and adjunctive therapies continue to expand their role in achieving durable and patient-centered outcomes in sleep apnea management.

Objectives: Torus mandibularis (TM) is a benign bony exostosis on the lingual surface of the mandible, typically developing from the third decade of life with slow progression; its etiology remains unclear. As TM excision causes no functional or aesthetic disadvantages, its use as autologous bone graft material (e.g., for pre-implant or sinus lift augmentation) has been suggested. In this study, we investigate the prevalence and expression of TM in a southern German population with regard to age and gender. Additionally, we examine whether TM undergoes dynamic changes over time, with the hypothesis that TM may show temporal growth. Material and Methods: A retrospective analysis of CBCT scans from 210 randomly selected patients (105 males, 105 females) was performed. Patients were divided into three age groups (≤40, 41–60, ≥61 years; 70 per group), and TM was measured using OsiriX MD. For the longitudinal study, 146 CBCTs from 73 patients were compared over intervals of 2–9 years. Surface changes were assessed via 3D overlay using GOM Inspect. Results: TM was found in 30.5% of patients, and its prevalence was significantly higher in males (38%) than females (23%), with no age-related differences identified. Most TMs measured <2 mm (n = 51); only five exceeded this size. No dynamic growth was observed over time. Conclusion and Clinical Implications: TM is a common anatomical variant, more frequently detected through 3D imaging than clinical examination. In most cases, size remains minimal (<2 mm), limiting its clinical use as augmentation material in rare individual cases. Full article

Background: Stable post-surgical wound healing surrounding teeth and dental implants is essential for achieving excellent clinical outcomes, both during the initial phases of treatment and over the long term. Objectives: This work follows the new emerging trend of case-based literature reviews. The aim of this review includes providing clinical findings from case series that demonstrate the efficacy of using blue^®m oxygen treatment to promote post-surgical wound healing in patients that underwent periodontal and dental implant surgeries. In addition, a systematic review of the literature aimed to answer the focused research question: “In periodontal and implant surgeries, what are the aftercare protocols used to maintain optimal wound healing?” Case Presentation: One clinical case report involved the presentation of complex periodontal surgery. The other two cases focused on advanced implant surgeries. All patients were treated post-surgically with the local application of an oxygen-based therapy (blue^®m) gel. This therapy was further emphasized during the wound-healing phase by instructing patients to maintain thorough dental hygiene using toothpaste and mouthwash containing a similar oxygen-release formulation (blue^®m). Patients achieved satisfactory treatment outcomes. Systematic Review: PubMed and EMBASE were used in order to search for relevant studies in the scientific literature published up until June 2025. Only human clinical studies that used a specific protocol in regard to aftercare wound healing after periodontal or dental implant surgeries were included. As a result, 27 clinical studies were included. The outcome data were categorized and summarized. Conclusions: The use of local oxygen-based therapy showed a positive effect as a conventionally used aftercare modality in maintaining optimal post-surgical wound healing, following periodontal and implant surgeries. Further clinical studies are needed. Full article

Background/Objectives: Emerging evidence links diabetes to increased cancer risk. This study aimed to assess the association between diabetes mellitus (DM)(type 1, type 2, or gestational) and the development of head and neck cancer. Methods: An umbrella review was conducted using systematic searches in Cochrane, EBSCO, Wiley, ScienceDirect, and PubMed (January 2000–January 2024), registered in PROSPERO (CRD42024512151). Included were systematic reviews (SRs) and meta-analyses (MAs) of observational studies. Article selection followed the PRISMA guidelines; the quality and risk of bias of the selected studies were assessed with the Joanna Briggs Institute Checklist. The GROOVE tool was used to identify double counting. Two independent reviewers screened studies, with a third resolving disagreements. Results: Seven SRs were included. While DM has been widely examined in cancer research, few studies specifically targeted head and neck cancers. Of the 20 associations between various cancer sites and diabetes types, 9 (45%) showed a statistically significant positive correlation. The strongest evidence was for overall cancer risk (RR = 1.22, 95% CI: 1.16–1.29, p < 0.001). Oral cancer showed elevated risks (RRR = 1.13, p = 0.009; OR = 1.32, p < 0.001; HR = 1.73, p < 0.05; RR = 1.28, p < 0.05). Increased risks were also observed for oropharyngeal (RR = 1.18; HR = 1.53), head and neck (HR = 1.47), and nasopharyngeal cancer (OR = 1.40), all p < 0.05. Heterogeneity was low in two reviews, unreported in one, and high in four. Five SRs reported associated risk factors. Conclusions: While some associations between DM and cancer appear significant, evidence remains limited and inconsistent, particularly for oral cancer. Further standardized, high-quality research is needed to clarify the link across head and neck cancer subtypes. Full article

Background: Periodontitis is a chronic inflammatory disease influenced by host aging, yet the specific effects of aging on disease susceptibility remain unclear. Objective: This study aimed to evaluate whether aging increases susceptibility to Porphyromonas gingivalis (P. gingivalis)-induced periodontitis in a murine model. We formulated the null hypothesis that age does not affect susceptibility to periodontal bone loss. Methods: Young (8 weeks) and aged (78 weeks) male C57BL/6 mice were randomly assigned into four groups: young control, young infected, old control, and old infected (n = 8 per group, except for old control, where n = 7). Experimental periodontitis was induced by oral application of P. gingivalis suspended in 5% carboxymethylcellulose (CMC), administered every other day, for a total of three applications. Alveolar bone loss was assessed 39 days after the last inoculation using histomorphometric measurement of buccal distance from the cemento-enamel junction to the alveolar bone crest (CEJ–ABC distance) and micro-computed tomography (μCT) at mesial and distal interdental sites. Bonferroni’s correction was applied to the Mann–Whitney U Test to determine statistical significance. A p-value of less than 0.05 was considered statistically significant. Results: Morphometric analysis showed significantly greater buccal bone loss in infected mice versus controls in both age groups (young: 0.193 mm vs. 0.100 mm, p < 0.01; old: 0.262 mm vs. 0.181 mm, p < 0.01). μCT analysis revealed that interdental bone loss was significant only in aged infected mice (mesial: 0.155 mm vs. 0.120 mm, p < 0.05; distal: 0.185 mm vs. 0.100 mm, p < 0.01), and not significant in young infected mice. Conclusions: Aging significantly exacerbates P. gingivalis-induced alveolar bone loss, particularly in interdental regions. These results allowed us to reject the null hypothesis. This study validates a clinically relevant murine model for analyzing age-related periodontitis and provides a foundation for investigating underlying molecular mechanisms and potential therapeutic interventions.

Background: The aim of this study was to assess the experiences and attitudes of dentists toward treating patients with mental disorders and to investigate how these attitudes correlate with factors such as sex, age, and years of clinical experience. Methods: A cross-sectional pilot study was conducted from March to July 2021 via an online questionnaire. The questionnaire consisted of four sections: demographic information, self-assessment of experiences and attitudes toward treating patients with mental disorders, knowledge of psychotropic drugs and their interactions, and personal experiences with patient care. Results: Overall, 101 dentists, mostly females (78.22%), completed the questionnaire, of which 65.35% consistently checked whether their patients were taking psychotropic drugs and 48.51% inquired about mental disorders when taking medical history. Still, 39.60% reported unpleasant experiences when treating such patients—mostly female dentists—and as many as 14.85% of all dentists refused to treat them. More than 94% of dentists recognized that patients with mental disorders are at greater risk for poor oral health and in need of early referral and professional support. Older dentists demonstrated better knowledge of oral manifestations and drug interactions relevant to dental treatment. Conclusions: Our findings highlight the need for improved training, an interdisciplinary approach, and greater dissemination of new scientific evidence for managing patients with mental disorders in dental practice. Considering that this is a pilot study using a combination of non-probabilistic convenience and snowball sampling method, the findings should be considered preliminary and interpreted with caution, as the sampling method limits the ability to make statistical inferences.

Objectives: This review examines the efficacy of each laser type in the field of periodontal surgery and analyzes published articles that focus on the use of lasers in periodontal surgery. Methods: Automatic and manual searches were made in 3 separate databases (PubMed, Embase, and Cochrane) with the aim of finding all published articles of the last 15 years up until December 2023 that describe the clinical manipulation of diode, erbium:yttrium-aluminum-garnet (Er:YAG), erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG), neodymium yttrium-aluminum-garnet (Nd:YAG), and carbon dioxide (CO₂) lasers for periodontal surgical procedures in humans. Results: A total of 18 studies were selected for inclusion, all of which compared the usage of a laser type to conventional periodontal surgical techniques with their main follow-ups being in 3, 6, or 9 months. Conclusions: There are a variety of laser types, each with different settings and wavelengths, that can be applied to the established aspects of resective and regenerative periodontal surgeries. A significant majority of the publications, 10 of the 12 studies, that include diode lasers as an adjunctive show an improvement in clinical results compared to traditional surgical techniques alone, while 2 articles studied the Er:YAG laser and 1 article studied the Er,Cr:YSGG laser, with all 3 of them failing to completely test their therapeutic capabilities and indicating similar results to conventional surgery. The Nd:YAG laser was featured in 3 studies, with 1 study showing superior results for the laser group, another study showing the negative influence of the laser, and the 3rd study being inconclusive. The CO₂ laser was used in 1 study and showed better clinical results for the laser group. Diode lasers have been proven to produce additional therapeutic results, but there is a need for further investigation of erbium family lasers along with the Nd:YAG and CO₂ lasers, as the current provided literature contradicts their potential healing capabilities.

Background/Objectives: Craniofacial microsomia (CFM), previously known as hemifacial microsomia, is a congenital condition involving structures derived from the first and second pharyngeal arches. CFM is characterized by asymmetrical craniofacial growth, affecting the mandible, ear, orbit, soft tissues, and facial nerve. Functional therapy is among the treatment options for mild to moderate cases. This study aimed to assess the effect of functional therapy on mandibular growth in patients with CFM by comparing mandibular and condylar height on the affected and unaffected sides, using pre- and post-treatment panoramic radiographs. Methods: A retrospective longitudinal study was conducted on 14 patients treated with functional therapy with the Asymmetrical Functional Activator (AFA) appliance. Mandibular ramus height (Co-Go) and condylar height (Co-Is) were measured bilaterally on pre- (T0) and post-treatment (T1) panoramic radiographs. Growth differences and rates were analyzed using descriptive and inferential statistics. Results: A significant increase in the mandibular ramus height (Co-Go) and in condylar height (Co-Is) was observed on the affected side from T0 to T1. The increase in mandibular ramus height was significantly greater on the affected side compared to the unaffected side (p = 0.0016). Although condylar height increased significantly on both sides over time, the difference in growth rate between sides was not statistically significant (p = 0.7148). Conclusions: Functional therapy may contribute to reducing mandibular asymmetry in CFM patients by enhancing the growth of the affected mandibular ramus, but the asymmetry may still be present at the end of treatment. These findings support its use in the early management of mild to moderate CFM. Full article

Background: Due to limitations of fluoride (F) treatment as a main caries preventive measure, it is important to consider the use of other dental caries preventive measures to reduce caries prevalence, especially in its early stages. Recently, new remineralizing agents appeared on the market, with their commercial availability in a variety of oral care products. Objectives: The purposes include providing a scoping review that represents caries remineralizing efficacies of only commercially available products and their existing adverse effects (if it is presented) and ensuring that only evidence-based approved products are included. Methods: The following databases were used in searching scientific literature on 28 October 2024: PubMed, PubMed Advanced Search, MeSH database, and PubMed Clinical Queries. The study selection criteria were as follows: for laboratory, in vitro, and/or in situ—remineralization of enamel-scanning electron microscopy, spectroscopy, microhardness test, light microscopy, profilometry, transverse microhardness microradiography, integrated mineral loss, light microscopy, photothermal radiometry; if it was a randomized controlled trial—CONSORT protocol, ICDAS system (to detect dental caries), diagnostic additional devices; antibacterial ability-colony forming units, DNA-based sequencing, scanning electron microscopy, crystal violet staining, and confocal laser scanning microscopy. Results: This review includes 98 papers: 14 of them describing the current status of caries patterns in the world, 60 studies (45 laboratory studies and 15 RCTs), and 24 systematic reviews were analyzed in order to detect whether new remineralizing agents can replace fluoride in further caries prevention. Conclusions: All reviewed new remineralization agents could be used without additives to treat early caries lesions, but the combination with F promotes better remineralization. Only HAP demonstrated its potential to serve as an alternative to fluoride in oral care products. However, further clinical studies are needed to prove its role in the remineralizing process of initial caries lesions. One also needs to ensure that both the clinical trials and in vitro lab studies use the best gold standards to validate any changes in the tooth structure, both remineralization and demineralization.

Background: Class II Division 1 malocclusion is often characterized by an increased overjet, which has traditionally been considered a negative predictor of aesthetic outcomes, treatment efficacy, and long-term stability. Although early two-phase treatment is generally perceived as less effective than a single-stage pubertal peak intervention, it may be beneficial in cases with concerns such as trauma risk or bullying. This study aimed to assess the relationship between initial overjet and sagittal correction (as measured by the ANB and WITS indices) to identify a threshold beyond which two-phase treatment might be more effective. Methods: A retrospective analysis was conducted on 58 patients (mean age: 9.01 years), all of whom were treated consecutively with the Manni Telescopic Herbst Appliance. Lateral cephalograms taken at the start (T0) and end (T1) of Herbst treatment were analyzed to evaluate changes in skeletal and dental parameters. Results: A significant positive correlation was found between higher initial overjet and increased skeletal sagittal correction. Specifically, for every 1 mm increase in overjet, there was a 0.65 mm reduction in the WITS index and a 0.30° decrease in the ANB angle (p < 0.01). These effects were more pronounced when the initial overjet exceeded 8.0 mm. Conclusions: The Manni Telescopic Herbst Appliance demonstrated enhanced skeletal correction in patients with larger initial overjet values, particularly when the overjet exceeded 8.0 mm. This suggests that early two-phase treatment may be especially beneficial in such cases. Full article

Background/Objectives: Orthodontic camouflage is a treatment strategy designed to address mild to moderate skeletal discrepancies through dental compensation when growth modification or orthognathic surgery (OGS) is unsuitable or declined by the patient. This report highlights the treatment of a child with a skeletal Class II pattern, Class II division 1 malocclusion, a 10.8 mm overjet, traumatic overbite, and unilateral temporomandibular joint (TMJ) ankylosis on the left side. Methods: The treatment plan focused on correcting the proclination of the maxillary incisors and improving the facial profile. A non-extraction camouflage approach using pre-adjusted edgewise appliances was implemented following a gap arthroplasty procedure on the left TMJ. Results: The patient achieved a satisfactory treatment outcome, with an ideal static and functional occlusion and significant improvement in facial esthetics. The approach effectively managed the severe mandibular retrognathia and TMJ ankylosis without OGS, thereby minimizing the risk of progressive condylar resorption. Conclusions: This case underscores the importance of personalized treatment plans tailored to each patient’s dental, skeletal, and individual needs. It demonstrates that non-surgical camouflage treatments can be a viable alternative for addressing severe mandibular retrognathia with TMJ ankylosis, achieving favorable esthetic and functional outcomes.

Interim fixed dental prostheses (FDPs) play a crucial role in maintaining oral stability during the construction of final FDPs. Traditionally, interim FDPs were fabricated using conventional methods. However, advancements in digital dentistry have introduced computer-aided manufacturing (CAM) techniques, including milling from prefabricated blanks and three-dimensional (3D) printing using light-sensitive resins, as common production methods. The aim of this review was to accumulate data on various fabrication techniques for interim FDPs, the materials used in their production, and the impact of each technique on key factors influencing the success of interim FDPs. We concluded that each technique for fabricating interim FDPs has its own advantages and limitations, and all can be effectively utilized for FDP production. However, digital techniques provide superior quality compared to conventional methods, particularly for long-term use. Full article

Background/Objectives: Although there is a general consensus that patients should have dental evaluation before heart valve surgery, data on the extent and complications of this evaluation are scarce. The objective was to analyze safety and feasibility of dental evaluation in patients undergoing heart valve surgery. Methods: A retrospective chart review of patients referred for dental evaluation prior to heart valve surgery in 2021–2023 was conducted. Demographic, medical, and dental data were recorded. The number and type of dental procedures and their complications were recorded, along with the number of appointments and the time required to achieve dental clearance for heart valve surgery. Results: One hundred and fifty-three patients were referred in the observed period. The predominant procedure was tooth extraction, accounting for 76 (49.7%) cases. Complications were recorded in 3 (1.9%) patients, with delayed bleeding being the most prevalent issue, occurring in 2 (1.3%) patients. The median time required to obtain dental clearance for cardiosurgical procedure was 1 day, with 124 (81%) patients obtaining clearance in a single appointment. No dental emergencies were observed during hospital admission for the cardiosurgical procedure. Conclusions: Our results suggest that dental evaluation before heart valve surgery can be conducted in a reasonable amount of time with a low complication rate and without the need to delay cardiosurgical procedures.

Objective: This study aimed to evaluate and compare the knowledge and attitudes of dentists and dental students regarding the early diagnosis of oral cancer. Study Design: Data were collected using a questionnaire administered to students on an integrated master’s degree in dentistry and to dentists. The data were then entered into SPSS, where they were statistically processed. Results: A total of 192 responses were considered (102 from dentists and 90 from dental students). Although both groups correctly recognized the gender most affected by the pathology, as well as the most common type of oral cancer, only 22.5% of dentists and 14.4% of students knew how to identify the sites with the greatest potential for malignancy. In both cases, the majority carried out a thorough intraoral assessment. Only less than half have ever performed a biopsy during their clinical practice. Only 4.9% of dentists and 3.3% of students consider their ability to diagnose pathology to be very good. Conclusions: Some gaps were observed and should be addressed, particularly in terms of knowledge about lesions with malignant potential. Therefore, it is crucial to invest in training in this area to halt the progression of this pathology. Full article
