Background: Recently, research in the field of caries prevention is emphasizing upon identification of edible non-toxic compounds that can interfere with the formation of cariogenic biofilm.

Aim: This trial aimed to assess the effectiveness of non-dialyzable material (NDM) containing cranberry mouth rinse (C-MR) on the Streptococcus mutans (S. mutans) counts and compare with that of a sodium fluoride (F-MR) mouth rinse.

Methods: 280 children (8-12 years old) were enrolled in this double-blind single center, parallel, one-month, IRB/IEC approved non-inferiority trial. The participants fulfilling the inclusion criteria were randomly allocated into one of the two groups: C-MR and F-MR. All participants were given verbal and written instructions about at-home mouth-rinsing regimen under parental supervision for a month. Dental plaque samples were collected before and after a month of mouth-rinsing and subjected to culture techniques. S. mutans counts were assessed and compared in both groups. Primary outcome was the difference in the S. mutans counts between two interventions. Both intention-to-treat (ITT) and per-protocol analysis were carried out using two-sample t test with equal variance.

Results: The mean S. mutans counts (after log transformation) in C-MR group were: 14.66 (90% CI 14.4,14.9) at baseline and 12.85 (90% CI 12.5, 13.2) colony-forming units/ml (CFU/ml) at one-month post intervention (p = 0.001); while these counts were 14.69 (90% CI 14.5, 14.9) at baseline and 12.71 (90% CI 12.3, 13.1) at one-month intervention in F-MR groups (p = 0.001). ITT analysis showed an inter- group difference of 0.14 CFU/ml (90% CI - 0.32,0.59) in post-SM counts between groups (p = 0.629).

Conclusion: The study demonstrated that the cranberry mouth rinse was non-inferior to the fluoride mouth rinse in terms of S. mutans levels change. Cranberry-based mouth rinse can be used effectively to reduce the S. mutans counts in children.

Purpose: This study aimed to evaluate stress levels and stressors amongst dental students, general dentists and paediatric dentists treating paediatric patients.

Methods: This study was conducted on 664 dentistry students, general dentists and paediatric dentists in Turkey. Data were collected through an online questionnaire consisting of demographic characteristics and the Pedodontic Practice Stress Scale (PPSS). Stressors when treating paediatric patients were compared between the groups. The scores obtained from the questionnaire were analysed. Compliance with normal distribution was analysed according to Kurtosis-Skewness values. One-way analysis was used to compare the scale scores (p < 0.050).

Results: Of the participants, 74.54% were female and 25.46% were male. The females showed a significantly higher level of stress, compared to the males (p = 0.001).When compared according to the level of education, the mean total stress scores did not differ (p = 0.211), but the mean complication score was found to be statistically significantly higher in paediatric dentists (p = 0.001). In addition, the lowest mean stress score was found in dental students. Statistically significant differences were found in all sections of the PPSS scale in terms of the ability to manage a paediatric patient as an adult patient and the importance of knowing child psychology theories.

Conclusion: Factors, such as the educational status, the number of patients treated, the behaviour of the patient's relatives and the potential to communicate with them, cause variable stress in dental students and general and specialist dentists working with children.

Purpose: The aim of the present was to assess the association between MIH and tooth agenesis (TA) in orthodontic patients from the Federal University of Rio Grande do Norte, Natal, Brazil.

Methods: A cross-sectional study was performed to evaluate the presence of MIH and TA in a sample of 371 pretreatment orthodontic records from patients aged 9-18 years. Statistical analyses were performed using the Chi-square and Fisher's exact tests, and logistic regressions.

Results: There was a statistically significant association between the prevalence of tooth agenesis and MIH. A higher percentage of third molar agenesis, maxillary premolar agenesis, and mandibular second premolar agenesis was observed among children with MIH-affected teeth. Patients with MIH had a 2.43 times greater chance of third molar agenesis, and a 5.88 times higher likelihood of mandibular premolar agenesis.

Conclusion: There is a weak association between MIH and TA. Furthermore, the presence of hypomineralised molars increases the risk of tooth agenesis.

Purpose: Generating adequate tongue pressure against the hard palate requires full-range mobility of the tongue. The study aimed to (1) determine the prevalence of restricted tongue mobility and ankyloglossia and (2) determine whether, in children with restricted tongue mobility, their condition also affects tongue pressure.

Methods: A cross-sectional study of healthy 6-8-year-old children from primary schools in central Vietnam was conducted in 2019. Restricted tongue mobility and ankyloglossia were graded using the tongue range of motion ratio (TRMR), with the tongue-tip-to-incisive papillae (TIP) for the anterior tongue tip and lingual-palatal suction (LPS) for the posterior two-thirds of the tongue. Tongue strength and tongue endurance were measured by the Iowa Oral Pressure Instrument. Statistical analysis investigated the associations between tongue mobility and tongue pressure measurement.

Results: Five hundred twelve children (46.5% female, mean age 7.2 ± 0.2 years) were assessed. The prevalence of anterior ankyloglossia and restricted mobility was 17.5%, with 16.2% cases of less than 50% mobility and 1.3% cases of less than 25% mobility. The prevalence of posterior ankyloglossia and restricted mobility with less than 30% mobility was 28.9%. Anterior restricted mobility was not a predictor of reduced tongue pressure. Posterior restricted mobility in LPS was independently associated with tongue strength but not tongue endurance.

Conclusion: Restrictions of posterior tongue mobility in ankyloglossia are more frequent than restrictions in anterior tongue mobility. Reduced tongue strength is related to mobility and the severity of restrictions in the posterior tongue. These findings suggest that restricted posterior tongue mobility may affect tongue muscle weakness.

Purpose: To assess the technical quality and clinical outcomes of non-surgical endodontic treatment of immature permanent incisor teeth with three different bioceramic plug materials and highlight variables which may influence treatment and quality outcomes.

Methods: This cross-sectional analysis forms part of a retrospective service evaluation of the technical quality and clinical outcome of orthograde root canal treatment carried out in the Paediatric Dentistry Department of Charles Clifford Dental Hospital (United Kingdom). Twenty-five cases were identified chronologically, using the electronic patient record system, for three bioceramic plug materials: Mineral Trioxide Aggregate (MTA), Biodentine, and TotalFill Putty. All radiographs were analysed using standard conditions. Intra- and inter-examiner agreement was calculated using Kappa and weighted Kappa tests. Data were collected using a data collection tool, entered into Microsoft Excel, and analysed using descriptive statistics, exploratory analysis with Chi-squared tests, and multivariable analyses (logistic regression).

Results: At 12-month review, the success rate for each apexification material was MTA (84%), Biodentine (88%), and TotalFill Putty (92%). MTA had the highest frequency of post-operative coronal discolouration, with Biodentine most associated with apical extrusion. A number of variables and trends that affect the clinical outcome were identified, including the presence of pre-operative resorption, the number of operators involved in treatment, the number of appointments to complete treatment, as well as how non-use of local anaesthetic during apical plug placement had no adverse effect on technical quality or clinical outcome.

Conclusions: MTA, Biodentine, and TotalFill Putty are highly effective apexification materials which produce excellent clinical outcomes. As such, logistical and situational factors, such as continuity of care from operators with increased levels of experience, skill and ability, rather than material choice, may be more prognostic regarding the technical quality and clinical outcome of immature endodontic treatment. Further high-quality evidence is required.

Purpose: The aim of this study was to investigate the potential for pulp revascularization in relation to patient age at the time of injury following luxation injury of mature anterior permanent teeth.

Materials and methods: A total of 93 teeth from 70 patients were included. The patients were divided into subgroups based on their age at the time of the injury.

Statistics: the Aalen-Johansen method was used to estimate the risks of pulp canal obliteration (PCO) and pulp necrosis (PN). The absolute 2 year risks of PCO and PN were obtained with cause-specific Cox regression and reported separately for each cohort, standardised to age at injury and degree of repositioning.

Results: For the group younger than 15 years of age, the risk of PN after 12 months was 62.3% [95% CI 44.9; 79.7] in the cohort from 1972 to 1980 and 28.6% [95% CI 4.9; 52.2] in the cohort from 2012 to 2020. For the age group 16-20 years, the risk of PN after 12 months was 66.7 [95% CI 40.0;93.3] in the cohort from 1972 to 1980 and 25% [95% CI 0.0;55.0] in the cohort from 2012 to 2020. For the age group between 21 and 25, the risk of PN after 12 months was 66.7% [95% CI 40.0; 93.3] in the cohort from 1972 to 1980 and 55.6% [95% CI 23.1; 88.0] in the cohort from 2012 to 2020.

Conclusion: There is potential for pulp revascularization in mature anterior teeth with lateral luxation in patients up to 25 years of age. The risk of PN appears to increase with age.

Purpose: The present umbrella review aimed to synthesize and critically assess the methodological and reporting quality of previous systematic reviews about the potential relationship between obesity or overweight and caries dental experience in pediatric patients.

Method: Electronic database and manual searches were conducted in PubMed, Embase, and Cochrane Library up to July 2023. The risk of bias assessment of eligible systematic reviews was performed using the Risk Of Bias In Systematic reviews (ROBIS) tool. A systematization of the results was carried out in order to understand the possible relationship between the two conditions.

Results: Electronic and manual searches identified 136 titles and abstracts. After the removal of duplicates, 15 full-text articles were assessed for eligibility. Six studies were excluded, resulting in 8 systematic reviews and 1 scoping review that met the inclusion criteria. Five were systematic reviews without meta-analysis and the rest were conducted with quantitative analysis.

Conclusion: Conflicting findings to date from this umbrella review suggest that the relationship between obesity and dental caries in children is still inconclusive and likely to be complex.

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.
