Background: Decision-making in dentistry is a complex process, and this study evaluated factors that influence dentists' approaches in permanent mature teeth with irreversible pulpitis.

Methods: An online questionnaire was distributed to a group of dental practitioners. The questionnaire surveyed dentists' opinions about the management of vital permanent teeth with irreversible pulpitis including a case scenario.

Results: Data from 262 respondents were analysed. Barriers to perform vital pulp therapy (VPT) included presuming it an inappropriate long-term treatment (29.7%), lack of knowledge, insufficient access to materials, inadequate training and lack of confidence. Patient's preference (79.44%) and tooth restorability (91%) were the most frequently reported factors influencing treatment decisions. Dentists aged 25-35 years and who have 1-5 years of experience ranked extraction as a more successful treatment (P = 0.008; P = 0.003, respectively). Non-Australian graduates ranked pulpotomy to be a more successful procedure (P = 0.007), and public sector/hospital practitioners favoured extraction more than practitioners from other sectors (P = 0.003). Postgraduates/specialists preferred pulpotomy (P = 0.012) more than general dentists. Participants' clinical approaches for the management of symptomatic irreversible pulpitis: root canal treatment (45.0%), indirect pulp capping (22.9%), direct pulp capping (15.8%), pulpotomy (17.1%) and extraction (6.3%).

Conclusions: Female, more experienced, overseas-educated dentists and endodontists preferred VPT for irreversible pulpitis in permanent mature teeth more than other participants. © 2024 Australian Dental Association.

Background: To evaluate whether the prevalence of traumatic dental injuries (TDIs) in permanent anterior teeth among school children is associated with sleep behaviours and disorders.

Methods: A cross-sectional study was carried out with a representative sample of schoolchildren aged 8 to 10 years (n = 1402) from Florianopolis, Brazil. Clinical examinations for TDIs were performed according to the classification proposed by Andreasen. Parents/caregivers completed a questionnaire addressing sociodemographic characteristics and sleep behaviours/disorders (sleep duration, insomnia, sleep rhythmic movement, snoring, and signs of sleep apnoea). Descriptive analysis and Poisson regression were performed.

Results: The prevalence of TDIs was 10.9%. Insomnia was observed in 3.0% of the children, snoring in 42.8%, sleep rhythmic movement in 27.9%, and signs of obstructive sleep apnoea in 33.6% of the schoolchildren. Most children (75.2%) slept less than eight hours a day. The prevalence of TDIs was higher among schoolchildren with an increased overjet (PR: 1.65; 95% CI: 1.15-2.35; P < 0.01), after adjusting for monthly family income, caregiver's schooling, and sleep behaviours. The prevalence of TDIs was not associated with sleep behaviours/disorders.

Conclusions: Parent-reported sleep disorders such as insomnia, sleep rhythmic movement, snoring and signs of sleep apnoea were not associated with the prevalence of TDIs in schoolchildren. © 2024 Australian Dental Association.

Mandible fractures are relatively uncommon despite the mandible being the most commonly fractured facial bone in the paediatric population. The aetiology of mandible fractures can be categorized as intentional (e.g. as a result of assault, peer-to-peer violence, family violence) or non-intentional (e.g. as a result of falls, motor vehicle crashes, sporting incidents). Peer-to-peer violence affects up to a third of male school aged children in Australia. This case report details the case of a paediatric patient with bilateral mandibular fractures who presented to a general dental practice after an episode of peer-to-peer violence. Clinical examination, radiographic findings and treatment are reported. This paper explores the experience and impact of peer-to-peer physical violence on the individual and his family. A review of the relevant literature is presented. © 2024 Australian Dental Association.

Background: Periodontitis is a common oral disease and the chronic inflammation caused by it may influence the development of cancers in the upper gastrointestinal tract. Many observational studies have established a relationship between the two, but the results are not entirely consistent.

Methods: Two-sample MR was performed using publicly available genome-wide association studies data for periodontitis, oral, gastric and oesophagal cancers. The Inverse Variance Weighting (IVW) method serves as the primary method, with MR Egger, Weighted Median, Simple Model and Weighted Model Algorithm methods as complementary methods to assess genetic causal associations. Cochran Q-test, MR-Egger regression and MR polytropic residuals and outliers were used to assess heterogeneity and horizontal pleiotropy.

Results: IVW results did not support a causal association between periodontitis and oral (OR = 1.00, 95% CI: 1.00, 1.00) and oesophagal cancer (OR = 1.00, 95% CI: 1.00, 1.00). Similarly, there was again no causal association between periodontitis and gastric cancer, which was integrated with an OR of 1.04 (95% CI: 0.97, 1.12). Complementary method results were consistent with IVW and heterogeneity and horizontal pleiotropy were not found in most studies.

Conclusions: The findings of our MR study do not support a causal relationship between periodontitis and oral, gastric and oesophagal cancers.

A congenitally missing lateral incisor tooth is commonly associated with both short and long-term clinical dilemmas, particularly for a growing patient. A unilaterally missing maxillary lateral incisor tooth creates a significant dental asymmetry in the critical aesthetic zone of the smile and potentially increases the difficulty of any subsequent orthodontic and restorative treatment. Carefully planned interdisciplinary management is required to address the challenges of anterior dental asymmetry, unilateral orthodontic space closure and to alleviate the concerns that accompany restorative implant placement in the anterior maxilla. The use of skeletal temporary anchorage devices has increased the predictability of orthodontic space closure, particularly for missing maxillary lateral incisor cases which were previously considered to be unsuitable.

Background: The aim of this study was to summarize existing data and perform technological prospecting on the effect of incorporating antifungal agents into denture base materials in inhibiting Candida spp., as well as to explore the antimicrobial properties of these materials.

Methods: A comprehensive electronic search was carried out in six major bibliographic databases (PubMed, Scopus, Embase, Cochrane Library, Web of Science and Lilacs) until February 2024. In addition, international patent databases were also examined. The search process, study and patent selection, data extraction and risk of bias assessment were carried out independently by researchers. The collected data underwent qualitative analysis.

Results: A total of 10 718 articles were identified in the searched databases, of which 40 documents were included for qualitative data analysis (articles: 31; patents: 9). The majority of the studies focused on investigating tissue conditioners (n = 14) and acrylic resins (n = 14). The primary antifungal agents studied were nystatin (n = 15) and fluconazole (n = 13). The most commonly utilized microbiological evaluation methodology was the agar diffusion test (n = 16), followed by the microdilution (n = 7) and biofilm formation assays (n = 7). All of the studies investigated the inhibitory effect of these materials against Candida species.

Conclusion: The incorporation of antifungal agents into denture base materials has been extensively studied and has shown a significant inhibitory response against Candida spp. across various methodological assays.
