Aim: Pre-eruptive intracoronal resorption (PIER) defects constitute an important part of anomalies associated with unerupted teeth. However, these defects are usually overlooked by clinicians whilst interpreting radiographs. This systematic review was thus orchestrated to find the global prevalence of PEIR.

Methodology: A comprehensive database search was done until December 2022 for published articles on the prevalence of pre-eruptive intracoronal resorption following preferred reporting items for systematic reviews and meta-analyses guidelines. The review was registered in Prospero (CRD42024501668). The risk of bias was analysed for each study using the Newcastle-Ottawa Quality Assessment Scale for cross-sectional studies.

Results: In total 18 studies were included in the present systematic review. The subject prevalence was 3.54% (range 0.56-27.31%) and tooth prevalence of 0.695% (Range 0.073-2.12%). Males and females were equally affected with no difference based on geography and race. Mandibular teeth showed more incidence of PEIR than maxillary teeth. First premolars were most frequently affected in the mandibular arch, whilst canines were affected most in the maxillary arch.

Conclusion: Within the limits of the review, we presented for the first time the global prevalence of PEIR. The condition may be overlooked and could lead to potential complications, thus it is essential to promptly diagnose these defects, thus preventing any further complications. We further suggest that all extirpated soft tissue should be submitted for further evaluation to shed light on the pathogenetic mechanisms involved in the initiation and progression of the disease.

Aims: To quantitatively detect S. mutans, Bifidobacterium, and S. wiggsiae in occlusal biofilm from permanent first molars based on the Visible Occlusal Plaque Index (VOPI), and to analyse the association between their levels and the occlusal enamel caries occurrence following the diagnosis of the International Caries Detection and Assessment System (ICDAS).

Study design: One hundred twenty plaque samples were collected from children aged 6-8 years and divided into four groups (n = 30 each group) according to VOPI scores (0 = no visible plaque, 1 = thin plaque, 2 = thick plaque, and 3 = heavy plaque). Scores 0 and 1 were identified by running dental probe on the groove. Scores 2 and 3 were visually identified. ICDAS scores were recorded by scoring 0-3 (0 = sound tooth surface, 1 = opacity or discoloration of enamel after air drying, 2 = visual change in enamel when wet, and 3 = localised enamel breakdown).

Methods: DNA was extracted from plaque samples and performed quantitative real-time PCR using SYBR green and specific primers for total bacteria including the 16S rRNA gene sequences conserved in all bacteria (BAC16S), S. mutans, Bifidobacterium, and S. wiggsiae.

Results: Ages of the children were different amongst VOPI groups (p < 0.001). Levels of total bacteria (p < 0.001) and S. mutans (p = 0.026) increased when VOPI increased. The ratio of S. mutans to total bacteria (p = 0.015) and the ratio of Bifidobacterium to total bacteria (p < 0.001) decreased from VOPI 0 to VOPI 3. Significant differences in total bacteria (p < 0.001) and S. mutans (p = 0.018) were detected from VOPI 0 to VOPI 2. A difference in Bifidobacterium (p < 0.001) was detected from VOPI 0 to VOPI 1.

Conclusion: Quantities of total bacteria (p < 0.001), S. mutans (p = 0.02) and ICDAS scores (p < 0.001) and VOPI scores were positively correlated. Quantities of ratio of S. mutans to total bacteria (p = 0.003) and ratio of Bifidobacterium to total bacteria (p < 0.001) and VOPI scores and ICDAS scores (p < 0.001) were negatively correlated.

Purpose: The aim of the present study was to evaluate the factors associated with failure requiring extraction after placement of preformed metal crowns (PMCs) in primary molars. Radiographic caries depth at baseline (initial/moderate and severe) and placement technique (Conventional and Hall technique) and other patient-related variables were analysed.

Methods: Clinical and radiographic records from children aged 2-10 years who had at least one primary molar treated with PMCs between 2011 and 2019 were evaluated. Chi-square test, Fisher exact tests and logistic regression analysis (α = 5%) were performed to verify the relationship between the primary outcome and categorical variables (caries depth, restorative teachnique, jaw, tooth type and gender).

Results: A total of 244 teeth treated in 165 children were included in the analysis. A total of 18 failures were observed (7.4%), of which 17 were in deep caries lesions and in which 15 had the PMC placed according to the conventional technique. Both caries lesion depth and restorative technique were associated with treatment failure (p < 0.05).

Conclusion: Taking into account the limitations of this retrospective study, treatment failures requiring extraction occurred more often in deep caries lesions when treated with preformed metal crowns (PMCs) following the conventional technique when compared to the Hall Technique.

Aim: This study aimed to investigate the correlation between subjective pain threshold (SPT), daily pain recovery (PR) during the first postoperative week, and patient/surgical characteristics, while evaluating changes in SPT across multiple surgeries. Additionally, it assessed how perceived quality of life correlates with SPT and PR in adolescents undergoing lower third molar germectomy.

Methods: A prospective clinical study was conducted at the Paediatric Surgery Unit, Sapienza University of Rome, involving 51 patients aged 10-16 years undergoing lower third molar germectomy. SPT and daily PR were measured using the Visual Analogue Scale (VAS) during the first postoperative week, and quality of life was evaluated using the SF-12 questionnaire at 1-week follow-up.

Results: A total of 87 germectomies were performed, with 36 patients undergoing a second surgery. The mean age was 13.86 ± 1.81 years. Mean VAS scores increased from 4.2 ± 1.5 for Intervention 1 to 4.8 ± 1.6 for Intervention 2. Longer operative times were associated with higher PR scores on postoperative day 3. Higher PR scores correlated with greater limitations in daily activities and emotional well-being, while lower PR scores were linked to better self-perceived health.

Conclusion: SPT and PR are influenced by surgical duration and self-health perception. Shorter procedures and positive self-health perception contribute to faster recovery and improved postoperative quality of life in young patients.

Background: Non-traumatic dental conditions (NTDC) that present to the emergency department of a tertiary hospital tend to be related to dental caries, including facial cellulitis, abscess and toothache. This study aimed to report the types of dental conditions and the characteristics of children that presented to an urban tertiary hospital emergency department for NTDC.

Methods: Medical records were reviewed for children less than 19 years of age who presented to the emergency department over a 10-year period with a NTDC. Principal diagnosis, sociodemographic data and source of referral was obtained with treatment and investigations collated for those who were subsequently admitted.

Results: Across the total 4483 dental presentations, 2481 were NTDC. The most common age group was from 0 to 3 years of age (average 6.3) and 57.2% of children were male. Dental caries related diagnoses were the most common reasons for emergency department presentations. A total of 297 children were admitted for investigations and treatment.

Conclusions: Children present to emergency departments with caries related conditions more often than traumatic injuries. Targeted interventions are needed to ensure adequate oral health care access for children to avoid overburdening the emergency services in tertiary hospitals with NTDC.

Purpose: This study aimed to determine the prevalence of hypomineralised second primary molars (HSPM) and molar incisor hypomineralisation (MIH) in cleft lip and/or palate (CL/P) patients.

Methods: A retrospective analysis of intraoral photographs of CL/P patients was done. All patients born between 2000 and 2011, and visiting the cleft team of the Erasmus Medical Center in Rotterdam, The Netherlands, were included. Their photos were scored on the presence and severity of HSPM and MIH using criteria formulated by the European Academy of Pediatric Dentistry. The outcomes were compared with data of the general population, extracted from the Generation R study.

Results: The photos of 535 CL/P patients were evaluated. The overall prevalence of HSPM in CL/P patients was 15.2%, of MIH 12.8%. HSPM and MIH prevalence was significantly higher (both p < 0.001) compared to prevalence in the general population. No significant differences were found in prevalence of HSPM nor of MIH in CL/P patients based on gender (p = 0.891 resp. p = 0.405), cleft type (p = 0.282, resp. p = 0.415), Pierre Robin (p = 0.837, resp. p = 0.169) or other comorbidities (p = 0.553, resp. p = 0.617). CL/P patients with HSPM were almost 3 times more likely diagnosed with MIH than CL/P patients without HSPM (OR = 2.57, p = 0.002).

Conclusion: The prevalence of HSPM and MIH is higher in patients with CL/P than in the general population.

Aim: To assess the knowledge, attitudes, and behaviours of Irish preschool teachers regarding the oral health (OH) of preschoolers aged 3-5 years old.

Methods: A validated 15-item questionnaire was completed by 90 preschool teachers in Dublin in January 2024. The questionnaire collected information on general demographics and assessed the knowledge and attitudes of teachers regarding early childhood OH. In addition, guided interviews were conducted to find out preschool teachers' awareness of OH training and resources, the challenges they face in organising OH education and their suggestions for improvement.

Results: Out of a cohort of 90 respondents, the mean number of questions answered correctly was 5.32 out of 9. One-third (34.4%) of the teachers said they learnt their OH knowledge from school or college, 8.9% from early childhood care training, 22.2% from their own dentist and 24.4% from other sources. Most teachers implemented OH education in some form whilst others said they had no time or resources. Qualitative data revealed a lack of formal OH training and knowledge, ideas for integrated OH activities, importance of collaboration and community engagement, barriers and challenges in implementation and need for mandatory OH training.

Conclusion: There are gaps in OH knowledge and lack of OH training for Irish preschool teachers. By identifying barriers and facilitators around OH training and resources for preschool teachers, the preschool teachers can be encouraged to create more supportive environments for improved OH.
