Background/objective: To evaluate the effectiveness of resin infiltration in managing anterior molar incisor hypomineralization (MIH) defects, focusing on color improvement, lesion size reduction, sensitivity outcomes and patient aesthetic perception. Enamel defects in MIH result from a combination of environmental, systemic, and genetic factors, indicating a multifactorial etiology. These defects, particularly in anterior teeth, pose significant aesthetic and emotional challenges due to their high visibility. This study provides one of the few prospective clinical evaluations of resin infiltration for anterior MIH lesions, assessing not only objective clinical outcomes but also patients’ aesthetic perception. It further introduces a patient-centered approach by comparing aesthetic evaluations made by children and dental professionals over time. Methods: A total of 109 MIH-affected anterior teeth were treated using Icon^® resin infiltration (DMG, Hamburg, Germany) in this registered prospective clinical study (ClinicalTrials.gov: NCT05597956). Participants were classified as children (6–12 years) and adolescents (13–17 years) according to standard pediatric age definitions. Of these, 101 teeth were available for evaluation at the 6-month follow-up due to patient loss to follow-up. The evaluation included photographic follow-up, measurement of lesion size and color, and assessment of sensitivity. During follow-up visits, patients rated the appearance of their lesions using the FDI scale. Results: Before treatment, spectrophotometric analysis showed that lesions exhibited a reddish hue (mean a* = 2.12), were distinctly yellowish (mean b* = 23.20), and clearly differed from surrounding enamel (ΔE = 8.62). The brightness level (L* = 69.81) indicated medium-high luminosity. Lesion size was reduced by an average of 4.5 percentage points. Significant increases in L values and reductions in a* and b* components were observed, with clinically perceptible ΔE changes. Sensitivity improved in 36.6% of patients, who reported a 1–2 point decrease on the SCASS. Moreover, patients’ aesthetic perception significantly improved after Icon^® infiltration resin. Conclusions: Resin infiltration produced noticeable improvements in color, reduced lesion size and sensitivity, and enhanced aesthetic perception, making it a valuable treatment option for managing MIH-affected anterior teeth in children.

Aim of the study: Anxiety about dental treatment is one of the main barriers to accessing dental services and, at the same time, a well-known problem for dentists. The main objective of this observational pilot study was to assess the prevalence and determinants of dental anxiety and severe forms compatible with dental phobia among adult dental patients and to explore their association with psychological distress, as well as patients’ preferences for methods to reduce pain and anxiety during dental treatment. Materials and Methods: We carried out a pilot observational study using two well-established questionnaires, namely the BSI-18 (Brief Symptom Inventory-18), which assesses the psychological distress of patients visiting the dentist, and the DAS (Dental Anxiety Scale), which evaluates dental anxiety toward dental treatment. The questionnaires were administered in independent dental practices in Timisoara, and the study was conducted between August 2024 and January 2025 on a sample of 231 persons. Results: The results of our study revealed a clear link between sources of oral health information, the high prevalence of anxiety as a personality trait, anxiety towards the dentist, and referral to dental services. Conclusions: The intensity of dental anxiety is higher before the therapeutic manoeuvre. It has been found, however, that people who are more educated experience lower levels of anxiety in specific situations. Full article

Background: Despite its crucial role in overall health, oral health is frequently overlooked within healthcare systems, partly due to the misconception that oral diseases are neither life-threatening nor directly disabling. This perception has led to an underestimation of the psychological, social, and economic burden associated with oral diseases. Τhe present study aimed to assess oral health status and oral health-related quality of life among dental patients attending a public Special Care Center in Greece. Methods: A cross-sectional study was conducted among 400 dental patients aged 18 years and older who visited a public Special Care Center for a routine check-up or a dental problem between September and October 2024. Data was collected through personal interviews and clinical examinations after informed consent was obtained. Oral health-related quality of life was evaluated using the Oral Health Impact Profile-14 (OHIP-14) and the Oral Impacts on Daily Performance (OIDP) questionnaires. Categorical variables were presented as absolute and relative frequencies, while quantitative variables were summarized as mean, standard deviation, median, minimum, and maximum. Normality was assessed using the Kolmogorov–Smirnov test. Bivariate analyses and multivariate linear regression models were performed, with statistical significance set at p < 0.05. Statistical analyses were conducted using IBM SPSS 23.0. Results: The majority of participants were female (56.3%) with a mean age of 50.4 years (SD = 14.9). Overall oral health-related quality of life was moderate (OHIP-14: Mean = 21.0, SD = 14.8; OIDP: Mean = 14.0, SD = 12.8). Patients who attended the center due to a dental problem reported significantly poorer oral health outcomes than those attending routine check-ups (p < 0.001). Poorer self-rated oral health, having ≥12 missing teeth, prosthetic restoration, and foreign nationality were significantly associated with worse oral health-related quality of life. Conclusions: Dental patients attending the Special Care Center demonstrated moderate oral health status, which was associated with psychological distress, physical disability, and social limitations. These findings underline the need for targeted public oral health interventions, especially for vulnerable population groups. Full article

Background: Early childhood caries (ECC) compromise the nutrition, growth, and quality of life in young children, and their relationship with breastfeeding practices remains disputed. Aim: To determine if prolonged breastfeeding increases the risk of dental caries in children aged under 71 months. Material and Methods: A systematic review of PubMed, Multidisciplinary Digital Publishing Institute, and Evidence-Based Dentistry, was conducted through August 2025, including observational studies, randomized trials, narrative reviews, and meta-analyses on breastfeeding and ECC. Results: Thirty-one studies involving 28,000 children were included. Exclusive breastfeeding for under six months halves ECC probability (OR 0.53–0.58), whereas breastfeeding beyond 12 months and nocturnal feeds increase probability by 60–86% (OR 2.35–7.14). Parental factors—high plaque levels, feeding-to-sleep, and skipped post-feed cleaning—strongly predict ECC (OR 8.51–75.6). Interventions combining feeding counseling with home visits or visual aids reduce ECC incidence by 22–32% (RR 0.68–0.78). Conclusions: Exclusive breastfeeding through six months is protective against ECC, but prolonged or nocturnal feeding heightens risk. Integrating structured oral health education into breastfeeding promotion is recommended. Full article

Objective: This is the first population-based study to separately examine whether preventive and treatment dental visits modify the association between stressful life events and toothache. Psychological stress may alter health-seeking behaviors and pain perception, potentially leading to symptom-driven rather than preventive dental visits. Methods: Cross-sectional data were obtained and analyzed from the 2019 wave of the Japan Gerontological Evaluation Study (JAGES), including 19,314 community-dwelling adults aged 65 years and older. Poisson regression analyses were conducted to examine the associations between stressful life events, dental visit history, and self-reported toothache. Results: Higher stressful life events were associated with greater toothache prevalence (PR = 1.189; 95% CI: 1.117–1.264). Preventive dental visits within the past six months were linked to the lowest risk, whereas recent treatment visits were associated with higher risk. Conclusion: Promoting regular preventive dental visits, particularly among individuals under high stress, may help reduce the likelihood of experiencing toothache among older adults. Full article

Background/Objectives: Parental presence or absence (PPA) in the dental operatory remains a central issue in paediatric behaviour guidance, commonly employed as a non-pharmacological approach, yet frequently perceived as a professional dilemma among paediatric dentists. Its behavioural impact on children during dental treatment remains debated. This systematic review evaluates the influence of PPA on children’s behaviour in dental settings and explores moderating factors. Methods: A PRISMA-guided systematic review was conducted in PubMed, Web of Science, and Scopus for primary studies published between 2005 and 2025. Eligibility criteria included clinical studies involving paediatric patients primarily aged 2–14 years, comparing parental presence vs. absence during dental visits. Results: The 16 included studies consisted of randomized controlled trials (n = 9), cohort studies (n = 3), and analytical cross-sectional designs (n = 4). Findings were heterogeneous; nine of sixteen studies reported that PPA improved cooperative behaviour, particularly in younger children (ages 4–6), those with higher IQ, or those with initially negative behaviour. Five studies found no significant effect, while two noted increased anxiety or disruptive behaviour with parental presence. Parenting style and cultural context influenced outcomes, with authoritative styles associated with better cooperation. Conclusions: PPA can enhance behaviour in specific subgroups but lacks universal benefits. Paediatric dentists should individualize its use according to each child’s developmental stage, emotional profile, and family dynamics, particularly parenting style, to optimize outcomes.

Background: Dens invaginatus is a rare developmental tooth anomaly that can occur in permanent, primary, and supernumerary teeth, with a tendency to affect the maxillary second incisors. It develops during odontogenesis due to the invagination of the enamel organ into the dental papilla. Methods: This study describes the endodontic management of a 24-year-old patient with a type IIIb invaginated tooth in the mandibular second molar. Clinical examination revealed no response to thermal and electrical stimuli, no response to vertical and horizontal percussion, and no pathological mobility. The depth of the gingival pocket was 8 mm. Root canal therapy was performed over three sessions. The patient remained asymptomatic during the treatment and follow-up visits. Results: Radiographs at 4-, 6-, and 9-month post-treatment showed healing of the periapical lesion. Conclusions: Due to the complex canal anatomy of invaginated teeth, confirming the diagnosis with cone-beam computed tomography (CBCT) is essential. Treating invaginated teeth presents significant challenges for clinicians, requiring a thorough understanding of the dental anatomical variability, advanced manual skills, and the use of specialized equipment.

Background: X-linked hypophosphatemic rickets (XLH) is a rare hereditary disorder characterized by renal phosphate wasting and impaired bone mineralization. Oral manifestations such as spontaneous periapical lesions and dental abscesses in the absence of caries or trauma may precede systemic features in XLH due to underlying dentin hypomineralization and enamel–dentin junction defects, and could serve as early diagnostic indicators. Case Report: We report on the case of a 4-year-old boy referred to our pediatric dental unit with recurrent intraoral fistulas persisting over the past year. Clinical examinations and an orthopantomogram revealed extensive root resorption and periapical pathology affecting multiple primary molars without evident caries or trauma. Laboratory investigations showed hypophosphatemia, elevated renal phosphate loss, and raised inflammatory markers (CRP (C-reactive protein) and granulocytes). Genetic testing of the child and his mother confirmed a diagnosis of X-linked hypophosphatemic rickets. Management: Due to behavioral challenges, treatment proceeded with difficulty over multiple visits. Endodontic treatment was initiated using a formalin–resorcinol technique; however, several primary molars developed progressive necrosis and required extraction. Orthodontic space maintainers were placed to preserve arch integrity and support future eruption. The patient remains under follow-up and is currently awaiting Burosumab therapy. Despite systemic management, spontaneous necroses of the primary molars persist, highlighting the refractory nature of dental involvement in XLH. Conclusions: This case underscores the pivotal role of pediatric dentists in recognizing systemic diseases through oral findings and demonstrates the challenges of managing XLH-related dental pathology, even under targeted systemic therapy. Early interdisciplinary collaboration is essential to optimize both dental and systemic outcomes in affected children. Full article

Objectives: This non-randomized and self-selected controlled intervention study aimed to examine the effects of simple nutritional guidance provided by registered dietitians on the oral function and body composition of patients in a general dental clinic in Japan. Methods: Among patients aged ≥50 years who visited a single dental clinic for regular maintenance, those who accepted and declined nutritional guidance were classified as being in the “guidance group (G group)” and “nonguidance group (nG group)”, respectively. The oral moisture content, masticatory performance, tongue/lip motor function, maximum tongue pressure, and swallowing function were assessed. Additionally, we assessed 10 body composition parameters using a body composition analyzer. Patients in the G group received monthly nutritional guidance from a registered dietician. At 3 months, changes in oral function and body composition were examined and between-group comparison in changes in dietary habits was performed. Results: A two-way analysis of variance revealed a main effect of time and an interaction between time and group for oral function only, and improvements in masticatory performance scores, maximum tongue pressure, and swallowing function were observed in the G group (n = 20). Compared with the nG group (n = 18), the G group had a significantly higher proportion of participants with a reported increase in the variety and amount of consumed food. Conclusions: Although this is the preliminary trial with a small sample and high risk biases, our findings suggest the possibility that 3 months of nutritional guidance at a general dental clinic in Japan may improve oral function.

Background and Objectives: Sjögren’s syndrome (SS) causes destructive salivary gland dysfunction with substantial oral morbidity. To synthesize practical, evidence-based approaches for early recognition, initial oral management, and timely referral to dental care. Materials and Methods: Narrative review of English-language literature from the Web of Science Core Collection and PubMed, prioritizing systematic reviews, randomized trials, and consensus guidelines. Results: Early oral signs include rapid multifocal root and cervical caries, burning sensations, and rising dental treatment needs. Unstimulated whole saliva ≤ 0.1 mL/min supports significant hypofunction and complements the 2016 ACR/EULAR criteria. Preventive care should combine dietary counseling, salivary stimulation, and topical remineralization. Adjuncts include high-fluoride toothpaste, biomimetic hydroxyapatite dentifrices, and casein phosphopeptide–amorphous calcium phosphate (CPP-ACP). However, evidence for fluoride varnish in SS remains mixed. Pharmacologic sialogogues require screening for contraindications. Conclusions: Embedding oral screening, simple salivary metrics, and a structured referral pathway into rheumatology visits can reduce preventable tooth loss and improve comfort, function, and treatment adherence.

Background: Oral health-related quality of life (OHRQoL) in children is an issue of growing interest in the scientific literature, with various studies focused on the adolescent population published in recent years. Nevertheless, few studies have evaluated the possible influence of the OHRQoL of mothers on that of their adolescent children. The aim of this study was to analyse the correlation between the OHRQoL of mothers and that of their adolescent children at their first oral examination. Methods: This retrospective pilot study was performed at the Dental Clinic of the University of Salamanca (Spain) between 2023 and 2025. The OHRQoL of 130 adolescent patients (from 11 to 14 years old) who visited the dentist for the first time was analysed. The mothers of these children were also interviewed to evaluate their OHRQoL; the adolescent patients completed the Spanish version of the Child Perceptions Questionnaire (CPQ-Esp_11–14) before their first dental consultation, and their mothers completed the Oral Health Impact Profile-14 (OHIP-14). Results: The study population consisted of 130 mothers (mean age: 43.0 ± 2.66 years) and their respective adolescent children (mean age: 12.5 ± 1.3 years) (65 boys and 65 girls). Among the adolescent patients, the highest score was obtained for the social well-being dimension of the CPQ-Esp_11–14 (25.01 ± 4.10), whereas the lowest was obtained for the oral symptoms dimension (10.88 ± 3.78). A higher score on the physical pain dimension of the OHRQoL for the mothers was related (p < 0.01) to higher scores on the emotional and social well-being dimensions of the CPQ-Esp_11–14 for their children. Conclusions: Considering the limitations of this study, it can be concluded that the OHRQoL of mothers has some effect on that of their adolescent children when visiting a dentist for the first time.

Aim: Early childhood caries (ECC) is a widespread and multifactorial oral disease that affects children globally. Parents’ knowledge, attitudes, and behaviors are crucial in preventing ECC and supporting oral health. This study evaluated Croatian parents’ understanding of children’s oral health, their awareness of ECC risk factors, and their oral hygiene practices. Materials and methods: A cross-sectional study was conducted using an anonymous and voluntary online questionnaire from October to December 2024 among 948 parents of children aged 1–7 years across Croatia. The study assessed parents’ knowledge of oral health, their understanding of the relationship between risk factors and early childhood caries, habits related to oral hygiene care, children’s experiences with oral health problems, parents’ self-assessment of their knowledge, as well as both their own and their children’s general and oral health and hygiene practices. Data were analyzed using descriptive statistics, Chi-square test, Mann–Whitney U test, and Kruskal–Wallis test. Results: Overall parental knowledge was moderate, with significantly higher scores among older parents, those with university education, healthcare workers, and families with higher incomes (p < 0.05). Parents demonstrated good awareness of the importance of supervising tooth brushing until age seven (93.8%) and fluoride use (81.8%); yet gaps persisted regarding bacterial transmission, tooth eruption, and early orthodontic evaluation. Preventive dental visits were frequently delayed, and only 25.0% of parents reported using interdental cleaning aids. Caries was the most common oral health issue among children (22.3%). Conclusions: Despite moderate awareness and some adherence to preventive measures, significant knowledge and practice gaps remain among Croatian parents. Targeted educational interventions and nationwide preventive strategies are necessary to strengthen oral health literacy and reduce ECC prevalence. Full article

Background: Hepatitis C (HC) remains a major public health concern, affecting approximately 50 million people globally. In addition to hepatic damage, HC induces extrahepatic manifestations (EHMs), including oral conditions such as oral lichen planus (OLP), xerostomia, and Sjögren syndrome-like (SS-like), which impair quality of life. The aim of this study was to investigate the possible association between certain extrahepatic manifestations of HC and the presence of risk factors. Methods: A cross-sectional study was conducted on 38 adults (22 males and 16 females; mean age 56.5 ± 8.6 years) with inactive HC. For each patient, demographic and clinical data were collected, including the following: frequency of dental brushing, frequency of professional dental hygiene visits, smoking, alcohol consumption, the presence of xerostomia, OLP, and SS-like. Logistic regression analyses and ROC curves were performed using R software to identify independent predictors for each condition. Results: OLP was present in 39.5%, xerostomia in 47.4%, and SS-like in 15.8% of patients. Female gender significantly predicted OLP and showed a borderline association with xerostomia. Smoking was weakly associated with xerostomia. No predictors were significant for SS-like. Conclusions: Oral hygiene and smoking are risk factors for oral EHM, their good control being important for the quality of life of these patients. Gender has also been shown to be a risk factor for these manifestations. Full article

Background: The psychosomatic effects of stress are risk factors for a range of dental and systemic diseases. This study used the massive Japanese national statistics database to clarify the association of psychological stress with subjective symptoms and conditions requiring hospital visits. Methods: Anonymized data from 93,690 respondents of the 2019 Japanese survey were provided for this study. From these data, those of 29,777 respondents aged 40–89 years were classified into stress groups based on their responses to the Kessler Psychological Distress Scale (K6). The response rates for symptoms and diseases were compared and analyzed using contingency tables and binomial logistic regression. Results: The items with the largest odds ratios in the univariate analysis were depression/other mental disease (7.60), followed by irritability (6.86) and health perception QOL (6.31). Among those with subjective symptoms, the proportion in the high-stress group was higher (15.1%), with a univariate odds ratio of 3.17. The results of the binomial logistic regression analysis, with subjective QOL as the dependent variable, were as follows: The explanatory variables with the highest adjusted odds ratios were stress group classification (3.14), followed by feeling physically tired (2.44) and sleep satisfaction (2.22). The stress group was associated with subjective symptoms, such as irritability and depression/other mental diseases, as well as with social factors, such as household structure and work hours. These results suggest the existence of specific symptoms, diseases, and environmental factors associated with high stress. Conclusions: The results suggest that stress may have a substantial impact on quality of life in later life. Therefore, healthcare measures for older adults should focus on the symptoms and diseases that tend to be associated with stress to mitigate their effects. Full article

Background and Objectives: Dental treatments of children with previous negative dental experiences are challenging and frequently require sedation or general anesthesia. Therefore, this study aimed to identify treatment pathways and factors associated with dental treatment under general anesthesia, nitrous oxide sedation, and chairside management among pediatric dental patients with adverse dental experiences. Materials and Methods: A retrospective cohort analysis was conducted on all new children aged 2–12 years with negative dental experience and treatment need visiting the Pediatric Department of the Dental Clinic, University of Greifswald, between 1 January and 31 December 2021. Results: Of the 640 newly presenting patients, 78 cases met inclusion criteria and were analyzed (mean age 6.7 ± 2.19 years, baseline dmft 4.5 ± 3.0 and DMFT 0.6 ± 1.2), with 88.5% having caries as chief complaint and 61.5% having a referral from other dentists. Eventually, only 25.6% received general anesthesia (mean age 5.1 ± 1.9 years, mean dt 5.6 ± 2.6), while 56.4% were managed with nitrous oxide sedation (mean age 7.3 ± 1.7 years, mean dt 3.3 ± 2.4), and 18% with chairside treatment (mean age 6.9 ± 2.8 years, mean dt 1.9 ± 2.4). Children of younger age, with higher dmft/dt scores and lower behavior ratings, were more frequently treated under general anesthesia. However, none of these variables could be identified as independent predictors for treatment under general anesthesia. Conclusions: Minimally invasive caries management, combined with appropriate behavior guidance and conscious sedation when indicated, can drastically reduce the need for general anesthesia in children, even among those with dental anxiety or previous negative dental experience.
