Objective: The aim of this study was to assess symmetry of developmental stage of permanent teeth between the left and right side of the jaw, as well as between the maxilla and the mandible.

Methods: A sample of 150 panoramic radiographs of individuals aged 6-20 years (69 males, 81 females) were selected from an open-access radiographic collection (Maxwell Museum of Anthropology's orthodontic collection, Albuquerque, USA). All developing immature permanent teeth (n = 489) were scored by the first author using Moorrees and Demirjian tooth stages. Symmetry of developing teeth was assessed between the left and right sides of the jaw, as well as between the maxilla and the mandible using McNemar test with p < 0.05 considered significant.

Results: No significant differences were found comparing left and right sides within the maxilla (n = 489), (McNemar, p = 0.759 M, p = 0.736 D), or within the mandible (McNemar, p = 0.262 M, p = 0.707 D) using either tooth scoring method. Percentage agreement for individual teeth between left and right sides was least for third molars. Significant differences were observed comparing maxillary and mandibular teeth for both tooth scoring methods (n = 978), (McNemar, p = 0.00 M, p < 0.001 D). Percentage agreement for individual teeth between the maxilla and mandible was least for incisors.

Conclusion: In the present sample, differences in tooth formation were not significantly different in left and right side of the jaw while a significant difference (p = 0.00 M, p < 0.001 D) was observed between maxilla and mandible.

Purpose: The aim of the present meta-analysis was to compare the rotary and hand files efficacy in primary teeth pulpectomy.

Methods: A structured search was conducted through four electronic bibliographic databases; MEDLINE via PubMed, Web of Science, Scopus, and Cochrane Library. The risk of bias was assessed using the Cochrane (RoB 2.0) tool. A meta-analysis was conducted using the Review manager software at a significance level of p < 0.05 The heterogeneity was measured by the Cochrane Q test and I 2. Sensitivity analysis was performed according to the leave-one-out method and the GRADE approach was used to assess the certainty of evidence.

Results: A total of 47 trials were included in the present review. Results showed that rotary instruments presented a significantly reduced instrumentation and obturation time. Rotary files, in root canal preparation of primary teeth, resulted in better root/tooth obturation. With rotary instrumentations, a significantly lower incidence of postoperative pain was reported after 6 h, 24 h, and 48 h. No significant differences were noted between the two groups regarding the children's behaviour and the clinical and radiographic success after 3 and 6 months, respectively.

Conclusion: Although no differences have been reported in the clinical and radiographic success between rotary files and manual files in primary teeth pulpectomy, rotary systems have been shown to provide better obturation quality, reduced instrumentation time, and less postoperative pain compared with conventional techniques.

Purpose: The purpose of this study is to evaluate the influence of photobiomodulation therapy on the regenerative potential of non-vital mature permanent teeth of healthy Canine dogs.

Methods: 54 mature roots, obtained from 27 premolars, in dogs, were selected and divided into three equal groups where Group I received regenerative endodontic procedures (REPs) using blood clot as a scaffold (positive control), Group II received similar treatment as Group I, followed by photobiomodulation therapy (study group) and Group III did not receive any intervention (negative control). Each group was further divided into three equal subgroups for the evaluation of the vascular area percentage and fibroblast count at 3 different intervals; 3, 10, and 15 weeks. Statistical analysis was performed with R statistical analysis software version 4.1.3 RESULTS: Data analysis for vascular area percentages, revealed an insignificant increase in mean values at 3 and 10 weeks for both the positive control and study group, and all values were significantly lower than the negative control (p < 0.001). At 15 weeks, there was an insignificant difference between the study group and the negative control group, with mean values was 9.76 ± 2.25, and 11.97 ± 2.37, respectively. However, both values were significantly higher than the positive control group (2.47 ± 1.0), (p < 0.001). Regarding fibroblast count, there was a gradual increase in mean values recorded at different intervals, reaching its maximum at the 15th week period; they were 41.40 ± 1.14, 56.60 ± 6.11 and 44.67 ± 17.04 for positive control, study group, and negative control respectively, with insignificant differences between the study group and negative control.

Conclusion: The results of this study support the revascularization of non-vital mature permanent teeth as an alternative treatment modality. Photobiomodulation could improve the construction of regenerated blood vessels and fibroblasts. However, further studies with longer flow-up periods and different animal models are recommended.

Purpose: There have been limited reports on hearing impaired (HI) children's oral health, but no data on their dental fear. The aim of this study was to assess dental fear and caries prevalence in HI children and adolescents.

Methods: Upon ethical approval, all elementary and junior/senior high schools for the HI in Greece were invited to participate in the study. Students were asked to fill in the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). High school students additionally answered the Modified Dental Anxiety Scale (MDAS). Both questionnaires were translated into sign language by the same licensed interpreter. Caries prevalence was evaluated by dmfs/DMFS indices. Statistics by SPSS Statistics 28 (IBM) included parametric and non-parametric tests (significance at p ≤ 0.05).

Results: 33 elementary and 53 junior/senior high school students (mean age = 10.89 ± 2.63 and 16.23 ± 1.33 years, respectively) participated in the study. Means of CFSS-DS were 24.1 ± 9.9 and 26.9 ± 10.5, respectively. Mean MDAS (high school students) was 11.3 ± 4.7. Mean dmfs was 2.5 ± 5.2 for elementary and mean DMFS was 3.5 ± 5.4 for elementary and 7.3 ± 9.0 for high school students, higher than similar-age general population. Dental fear was not significantly associated to age, gender, severity of hearing impairment (HI) or caries prevalence.

Conclusion: HI children present similar dental fear values, but higher caries prevalence compared to similar-age Greek hearing population.

Objective: Quantitative analysis of all articles on harmful oral habits through a bibliometric review.

Methodology: The search was conducted on August 08, 2024 using the Web of Science database. All papers addressing the topic were included without language or date restrictions. Editorials, conferences, and meeting abstracts were excluded. From the selected articles, the following data were extracted: number of citations in Web of Science, year and journal of publication, impact factor (IF-2022), study design, type of deleterious habit and study objective, country, continent, institution, author, and keywords. Data analysis was performed using SSPS and VOSviewer software.

Results: 208 articles were included. Publications occurred between 1983 and 2024. The most cited article had 123 citations. The journals with the highest number of publications were the Journal of Clinical Pediatric Dentistry (n = 11) and the journal with the highest IF was the International Journal Oral Science (IF-14.9). There was observed a higher prevalence of observational study designs (n = 178), non-nutritive sucking habits (n = 151), and an association between harmful oral habits and malocclusion (n = 93). Most articles originated in the European continent (n = 77), the most prevalent country was Brazil (n = 61), with emphasis on the University of São Paulo (n = 8). The most frequent author was Paiva SM (n = 8).

Conclusion: This global analysis reveals greater interest in occlusal damage and non-nutritive sucking habits. The participation of observational studies is more prevalent.

Objective: To evaluate whether the presence of dental caries in the primary anterior teeth of 1- and 2-year-old babies can predict the occurrence of severe dental caries in the primary posterior teeth of these children after a 3-year follow-up.

Methodology: This cohort study was carried out with 99 children and their guardians who were assessed at the beginning of the study and reassessed after 3 years. Severe caries in posterior tooth at the 3-year follow-up is the dependent variable. Caries in anterior tooth at baseline is the main independent variable. Other independent variables are family income, mother's education, oral hygiene, night oral hygiene, sucrose consumption, and history of toothache. Descriptive analysis, chi-square test, and Poisson regression were performed.

Results: The incidence of severe caries in posterior tooth was 3.33 times higher in children with caries in anterior tooth at baseline (95% CI 2.06-5.37). Children who belonged to lower-income families both at baseline and at follow-up (RR: 2.75; 95% CI 1.40-5.39), who did not perform night-time oral hygiene at baseline (RR: 1.76; 95% CI 1.10-2.80) and who had a frequency of sucrose consumption equal to or greater than twice a day, both at baseline and at follow-up (RR: 4.07; 95% CI 2.03-8.19) had a higher risk of developing severe dental caries in posterior deciduous teeth.

Conclusion: Children with dental caries in primary anterior teeth when they were babies have a higher incidence of severe caries in posterior teeth.
