Objectives: To evaluate the survival rate of minimally invasive semipermanent occlusal polymethyl methacrylate (PMMA) onlays/veneers in previous temporomandibular disorder (TMD) patients with severe tooth wear and with a loss of vertical dimension after up to 7 years.

Method and materials: This case series was designed as a follow-up evaluation with consecutive patient recruitment. All patients bearing the indication for this kind of rehabilitation were treated by the same clinician using the same adhesive methodology. The study included 22 patients (3 men/19 women), with a mean ± SD age of 50.7 ± 11.6 years. Controls followed within the first 4 weeks (and subsequently as required). Failure criteria included damage by fracture, chipping, and retention loss. Survival rates were determined based on the Kaplan-Meier analysis.

Results: 328 semipermanent occlusal/incisal veneers were included (142 maxillary/186 mandibular teeth). Almost 80% of the restorations were in place and in function when starting the follow-up treatment after 180 days; failures predominantly occurred within the first 3 to 6 months but proved reparable. Depending on the patients' priorities, scheduled replacements followed successively, and more than 65% did not show repair or any renewal needs for more than 360 days.

Conclusion: Within the limitations of this study the survival rates of occlusal veneers made of PMMA were sufficiently high to allow for consecutive treatment of the respective teeth by means of permanent restorations while preserving the restored vertical dimension. In patients with severe tooth wear and a TMD history, semipermanent restorative therapy with occlusal PMMA onlays/veneers would seem a noteworthy option.

Objective: Varying levels of sex hormones across the menstrual cycle in young systemically healthy females may alter tissue responses to plaque, resulting in increased gingival inflammation. Also, higher severity and prevalence of gingivitis has been demonstrated in adult women than men, attributed to hormonal changes. Further, it has been reported that gingivitis raises the levels of systemic inflammatory markers such as C-reactive protein. This interventional trial aimed to evaluate the effect of supragingival scaling on serum high-sensitivity C-reactive protein (hsCRP) levels along with periodontal parameters in systemically healthy women of reproductive age with natural gingivitis.

Method and materials: In total, 57 women of reproductive age were enrolled into two groups. The test group (n = 30) comprised systemically healthy women with gingivitis who received supragingival scaling. The control group (n = 27) included systemically and periodontally healthy women. Periodontal parameters (Gingival Index, Plaque Index, pocket probing depth, bleeding on probing) and serum hsCRP levels were recorded at baseline for both the groups. Follow-up of test group participants was done at 3 and 6 months.

Results: Serum hsCRP and periodontal parameters were significantly higher in the test group than in the control group at baseline, and this decreased significantly after treatment in the test group at the 6-month follow-up (P ≤ .05). Gingival Index, bleeding on probing, and hsCRP in the test group at 6 months were reduced to the baseline levels of systemically and periodontally healthy women.

Conclusion: Treatment of gingival inflammation can help in lowering the systemic and local inflammation to the levels of systemically and periodontally healthy women.

Objectives: This study aimed to evaluate the effect of the clinical removal of fixed partial dentures on oral health-related quality of life and the anxiety values of individuals and to determine the clinical factors of high anxiety levels.

Method and materials: In total, 300 participants were included in the study. Six different reasons for the clinical removal of fixed partial dentures (oral examination, denture renewal, endodontic treatment, tooth extraction, periodontal treatment, and composite filling restoration) were defined. The United Kingdom Oral Health-Related Quality-of-Life Measure (OHRQoL-UK), the Modified Dental Anxiety Scale (MDAS), and the Spielberger State-Trait Anxiety Inventory- State (STAI-S) and Trait (STAI-T) were answered. The reason groups were compared using one-way analyses of variance. Binary logistic regression analyses were performed to evaluate the risk factors for high anxiety.

Results: There was no significant difference in OHRQoL-UK scores (P = .279) among the reason groups, but there were significant differences in MDAS, STAI-S, and STAI-T scores (P = .004, P .001, P = .018, respectively) among the reason groups. Endodontic treatment, tooth extraction, and sex were determined to be risk factors, considering the anxiety scales.

Conclusions: Females are 2.2 times more likely to have trait anxiety than men. Although the effect of the reason for the clinical removal of fixed partial dentures on oral health-related quality of life was similar among the groups, it is concluded that endodontic treatment and tooth extraction reasons for the clinical removal of fixed partial dentures could be risk factors for high anxiety regardless of fixed partial denture usage time.

Objective: To determine the oral health status of patients on maintenance hemodialysis and to identify the factors influencing their oral health.

Method and materials: This observational study included 1,186 patients with chronic kidney disease who received maintenance hemodialysis across 33 hospitals in China. The patients were recruited for a questionnaire survey between April and August 2023 at Beijing Chaoyang Hospital using stratified sampling. Data collection tools included the General Information Questionnaire for Maintenance Hemodialysis Patients, the Oral Health Assessment Tool, the Pittsburgh Sleep Quality Index, and the Hospital Anxiety and Depression Scale. Spearman rank correlation coefficients were used to assess the relationships between the oral health of patients on maintenance hemodialysis and continuous variables such as sleep quality and emotional status. Multiple linear regression analysis was employed to explore the relationship between oral health and various variables.

Results: The oral health scores of the patients ranged from 8 to 22, with a mean score of 12.54 ± 2.63. The final model of the multiple linear regression analysis indicated a goodness of fit of 22.19%. Independent factors affecting the oral health of patients included smoking, the proportion of medical expenses, water consumption, sleep quality, and anxiety scores (all P .05). High levels of smoking, substantial medical expenses, poor sleep quality, and elevated anxiety scores were risk factors for poor oral health (all P .05). Adequate daily water intake served as a protective factor for oral health (P .05).

Conclusion: This study proposes targeted interventions to enhance the management and improvement of oral health in patients on hemodialysis, aiming to provide highly personalized and effective oral health care. These interventions are expected to improve oral health outcomes in future clinical practice.

Objective: This study aimed to evaluate the degrees of dependence and presence of bacterial plaque in children with autism spectrum disorder (ASD) and the quality of life of children and their caregivers.

Method and materials: This was a cross-sectional observational study. This study included 119 individuals with ASD and their caregivers. Data were collected through a sociodemographic questionnaire, WHOQOL-Bref, and Burden interview to measure quality of life and caregiver burden, respectively. The Autoquestionnaire Qualité de Vie Enfant Imagé questionnaire, adapted in game format, was applied to verify quality of life in children with ASD. An oral clinical examination evaluated the visible plaque index. The collected data were tabulated and organized for statistical analysis with a significance level of 5%.

Results: It was observed that 52% of the children had a severity of ASD level 1; 70% were dependent for general activities, and 65% were dependent for oral hygiene. Of the 77 children who thoroughly answered the questionnaire about their quality of life, 64.9% had good quality of life, and 35.1% had scores below 48, that is, low quality of life. In general, the caregivers generally presented quality of life with a rate of 60.95 (good) points on the scale. It was observed that gingival bleeding greater than 30% is two (ASD 2 + ASD 3) to three (ASD 3) times more likely to occur in patients who have higher levels of ASD (P < .004).

Conclusion: It was concluded that the quality of life of individuals with ASD was good, that most children are dependent for their daily activities and oral hygiene, and that they showed reasonable plaque control. On the other hand, the caregivers presented low quality of life and moderate burden.

Objective: Artificial intelligence (AI) applications in restorative dentistry have remarkably increased in the past 5 years. This review outlines the applications, promises, and limitations of AI in the most performed procedures in restorative dentistry.

Method and materials: An electronic search was performed in four databases: MEDLINE/PubMed, Embase, Web of Science, and Scopus. The search included articles published in English language without date restriction. Two independent reviewers assessed the eligibility of the studies and performed data extraction. Any discrepancy was resolved by the consensus of a third reviewer.

Results: A total of 33 studies were included in this review. For AI applications in restorative dentistry, the included studies were classified into three main groups: (1) diagnosis, detection, and prediction of the disease, (2) detection and prediction of the longevity of dental restorations, and (3) teeth detection and treatments. For each study, the AI model, type of dataset, sample size, and main results (accuracy, precision, sensitivity, and specificity) were reported.

Conclusions: AI systems are promising as advantageous aids for diagnosis, prediction, and treatment in dentistry, with a high degree of accuracy. Despite the AI promises, several limitations are still unresolved and must be addressed to bridge the gap between technology and clinical applications.

Objectives: This study compared the effects of leukocyte platelet-rich fibrin (L-PRF) and advanced platelet-rich fibrin (A-PRF) on patients' quality of life and the healing of palatal wounds after free gingival graft harvesting.

Method and materials: After free gingival graft harvesting, palatal donor sites of 36 patients were assigned to one of three groups: L-PRF group, A-PRF group, or palatal stent + periodontal pack group (control group). Wound healing was evaluated by H2O2 test. Pain was evaluated by visual analog scale and number of analgesics consumed. For patient quality of life, the Oral Health Impact Profile-14 (OHIP-14) questionnaire was utilized.

Results: Complete epithelialization was higher in the control group on day 7 than in the test groups (P < .05). Complete epithelialization was achieved in all groups 14 days postoperatively. Visual analog scale scores for pain and the number of analgesic tablets consumed were similar in all groups (P > .05). OHIP-14 total scores were similar in all study groups at 7 days postoperatively (P > .05). OHIP-14 total and physical pain score was lower in the L-PRF group than the A-PRF group at 14 days postoperatively (P < .05).

Conclusion: Aside from the slight superiority of L-PRF over A-PRF, it can be concluded that both PRF procedures have similar effects on palatal wound healing and quality of life.

Objective: The aim of this report was to review oral follicular lymphoid hyperplasia, with emphasis on palatal lesions.

Method and materials: A comprehensive search was performed on PubMed for case reports and case series of palatal follicular lymphoid hyperplasia published in the English language literature. Relevant data from collated articles was sought, including patient demographics, clinical manifestations, imaging modalities and findings, comorbidities, etiopathogenesis, lesional management, and lesional outcome. A new palatal case has also been provided to illustrate several features of this lesion.

Results: In total, 32 cases were assembled to establish clinicopathologic correlations, representing the largest aggregation of published cases. Most of the affected patients were at least 60 years old and with a decisive female predilection. The majority of lesions were ≤ 3 cm, appearing as normal color, purple-red or red, and varied from soft to firm. Notably, 32% of palatal follicular lymphoid hyperplasias were associated with denture wear, and lesional recurrence was recorded in 16% of cases. To date, none of the reported cases of palatal follicular lymphoid hyperplasia has undergone malignant transformation.

Conclusions: Palatal follicular lymphoid hyperplasias often arise as a reactive process. Critical histopathologic and histochemical assessments are necessary to establish benignity. Postoperatively, clinicians should follow patients for at least 5 years for recurrence and remain vigilant for neoplastic change as several published accounts of non-oral follicular lymphoid hyperplasias have undergone malignant transformation, usually to lymphoma.
