Aim: This study employed the willingness-to-pay (WTP) method to investigate parents' valuation of fissure sealant (FS) and fluoride varnish (FV) therapy.

Design: This cross-sectional analytical study was conducted in 2021 among 100 parents. The maximum WTP were collected using payment cards, an originally developed validated and reliable questionnaire, educational videos, and a hypothetical scenario. The data were analyzed using ANOVA, t-test, Pearson correlation coefficient, and linear regression tests (α = 0.05).

Results: The mean (±SD) WTP was 245 700 (±158 756.24) and 232380.0 (±166 561.71) IR Tomans for FS and FV, respectively. WTP was significantly higher among parents who visited private clinics (p < 0.05) and government employees. Both in the whole sample and in the public group, parents without supplemental insurance had lower WTP values. The WTP values elicited through the payment card method (p = 0.014) and the open-ended question (p = 0.031) for fathers with educational attainment below a high school diploma were significantly lower. There was no significant difference between the WTP values for these two therapies. Income level of the parents was the main indicator in the regression models, especially for WTP values of FS.

Conclusions: The demographic and socioeconomic conditions of parents as well as their insurance status were associated with the WTP values.

Background: Orofacial cleft is the most common craniofacial deformity, resulting in facial anatomical disorders.

Aim: To evaluate maxillary dental arch symmetry of children with unilateral complete cleft lip, alveolus, and palate before and after primary surgeries.

Design: A total of 27 dental casts were analyzed: (T1) Presurgical; (T2) Postsurgical 1; and (T3) Postsurgical 2. Six linear measurements were analyzed (I-C', I-C, I-T', I-T, C'-T', and C-T). Paired t test, Pearson correlation, and ANOVA, followed by the Tukey test, were conducted (α = 5%).

Results: The asymmetry was confirmed by I-C versus I-C' across all periods and I-T versus I-T' (at T1). The Pearson correlation test showed significant values for Δ1×Δ2 and Δ1×Δ3, but not for Δ2×Δ3. The longitudinal analysis showed that the I-C' mean was greater at T1 than at T2/T3 (p < 0.001). The I-C mean was smaller at T1 than at T2/T3 (p < 0.001). I-T' was greater only at T3 (p < 0.001). I-T, C'-T', and C-T means were greater at all periods.

Conclusion: The maxillary asymmetry of children with unilateral cleft lip and palate is inherent to the cleft type, evidenced by the maxillary hypoplasia in the smaller segment, probably higher in the anterior region (I-C').

Background: In recent times, bioceramic calcium silicates have gained attention due to high success rates with pulpotomy in primary teeth.

Aims: To evaluate and compare the clinical and radiographic outcomes of three different bioceramic calcium silicate cements in vital deciduous teeth treated with pulpotomies over a period of 24 months.

Design: Children aged 4-9 years, with deep dentinal caries (ICDAS 4-6) in primary molars, having no history of spontaneous pain or signs of non-vitality were included in the study. Following clinical and radiographic evaluation 117 primary molars diagnosed as having reversible pulpitis received pulpotomy treatment, after randomly being assigned into three groups based on the bioceramic calcium silicate medicament used: a pre-mixed syringe-loaded MTA putty (NeoPUTTY); a traditional powder-liquid hand mix MTA material (NeoMTA Plus), and a precapsulated, trituration mixed material (Biodentine). Clinical and radiographic evaluation was done at 6, 12, 18 and 24 months.

Results: The cumulative clinical and radiographic success for NeoPUTTY was 92%, NeoMTA Plus 97% and for Biodentine 95% and 89%, respectively, after 24 months follow-up.

Conclusion: The clinical and radiographic success rates of all three bioceramic calcium silicate cements were found to be high, with no significant differences over a period of 24 months.

Trial registration: Clinical trial registration number: CTRI/2021/03/031655.

Background: Physical punishment by caregivers affects approximately 60% of children between the ages of 2 and 14 worldwide.

Aim: To evaluate the association between physical punishment and paternal neglect of children and adolescents and toothache.

Design: This cross-sectional study included all schoolchildren between the ages of 9 and 19 from a small Brazilian town in 2016 (n = 329). Toothache was assessed through a structured questionnaire using the question: "In the last six months, have you experienced a toothache?" (yes/no). The main exposures consisted of six validated questions about negligence and six about physical punishment, both with three potential answers: Always (2 points), sometimes (1 point) or never (0 points). Logistic regression models were fitted to estimate the association between paternal physical punishment/neglect and toothache, adjusted for sex, age, family equivalent income and parents' level of education.

Results: Thirty-seven percent of the children reported no physical punishment, while 19% reported no negligence. The odds ratio (OR) of toothache for every 1 point increase on the abuse or negligence scale was OR = 1.27 (95% Confidence Intervals (CI) = 1.08-1.50) and OR = 1.10 (95%CI = 0.96-1.26), respectively. If the child's mother had started and/or finished university, the OR of toothache is lower.

Conclusions: Paternal physical punishment is associated with toothache.

Background: Disruption in odontogenesis can influence the normal development of both deciduous and permanent dentition resulting in anomalies in morphology, number, and position of teeth. Although dental anomalies are frequently reported in clinical practice, their occurrence in past populations from archeological contexts is rarely acknowledged.

Aim: To describe two cases of dental anomalies on two non-adult individuals from Italian archeological sites.

Design: Individual sex diagnosis was performed by analyzing amelogenin peptides from the dental enamel through liquid chromatography mass spectrometry (LC-MS/MS). Age-at-death estimation was based on stages of dental formation and eruption. Dental twinning and talon cusp were morphologically evaluated and classified following standardized scoring systems proposed by clinical literature.

Results: The first individual, a 3-4-year-old female from the Imperial Roman necropolis of Isola Sacra, presents the fusion of the upper right deciduous central incisor with a supplementary tooth; the second individual, a 3-3.5-year-old male from a Late Antiquity catacomb, shows a case of bilateral gemination on the upper permanent central incisors with a co-occurrence of dental gemination and talon cusp on the right one.

Conclusions: The cases reported here (the two anomalies in the individuals presented) are useful into understanding these dental conditions within past/archaeological populations.

Background: Dental caries and extrinsic black tooth stain (EBS) are prevalent among children, with current evidence suggesting a negative correlation between them. It is unclear whether the factors contributing to developing or preventing dental caries and EBS are connected or aligned.

Aim: To investigate the prevalence and associated factors of caries and EBS among children with primary, mixed and permanent dentitions.

Design: This was designed as a cross-sectional study. Probability proportionate to size sampling and simple random sampling methods were used to recruit children aged 5, 9 and 12. Three calibrated paediatric dentists conducted intra-oral examinations. Nutritional supplements, oral health-related behaviours and family background were collected. Bivariate analysis, negative binomial and binary logistic regression were performed.

Results: Caries and EBS prevalence were 83.7% and 4.7%, respectively. A decreasing trend in caries and an increasing trend in EBS prevalence were observed across three dentitions. Caries were associated with EBS, oral hygiene, vitamin intake, gender, food-pocketing habits, toothbrushing duration, dental attendance and socioeconomic status. EBS was more likely to occur in caries-free children (OR = 4.42, 95% CI 2.97,6.58, p < 0.001) and children without vitamin consumption (OR = 1.59, 95% CI 1.07, 2.36, p = 0.021).

Conclusion: The occurrence of caries and EBS varied across different dentition stages. Their risk and protective factors were not significantly aligned.

Background: Dens evaginatus is a dental morphological developmental anomaly. Failing to detect it may lead to tubercles fracture and pulpal/periapical disease. Consequently, early detection and intervention of dens evaginatus are significant to preserve vital pulp.

Aim: This study aimed to develop a deep learning model to assist dentists in early diagnosing dens evaginatus, thereby supporting early intervention and mitigating the risk of severe consequences.

Design: In this study, a deep learning model was developed utilizing panoramic radiograph images sourced from 1410 patients aged 3-16 years, with high-quality annotations to enable the automatic detection of dens evaginatus. Model performance and model's efficacy in aiding dentists were evaluated.

Results: The findings indicated that the current deep learning model demonstrated commendable sensitivity (0.8600) and specificity (0.9200), outperforming dentists in detecting dens evaginatus with an F1-score of 0.8866 compared to their average F1-score of 0.8780, indicating that the model could detect dens evaginatus with greater precision. Furthermore, with its support, young dentists heightened their focus on dens evaginatus in tooth germs and achieved improved diagnostic accuracy.

Conclusion: Based on these results, the integration of deep learning for dens evaginatus detection holds significance and can augment dentists' proficiency in identifying such anomaly.

Background: With the increasing popularity of online sources for health information, parents may seek information related to early childhood caries (ECC) from artificial intelligence-based chatbots.

Aim: The aim of this article was to evaluate the usefulness, quality, reliability, and readability of ChatGPT answers to parents' questions about ECC.

Design: Eighty questions commonly asked about ECC were compiled from experts and keyword research tools. ChatGPT 3.5 was asked these questions independently. The answers were evaluated by experts in paediatric dentistry.

Results: ChatGPT provided "very useful" and "useful" responses to 82.5% of the questions. The mean global quality score was 4.3 ± 1 (good quality). The mean reliability score was 18.5 ± 8.9 (average to very good). The mean understandability score was 59.5% ± 13.8 (not highly understandable), and the mean actionability score was 40.5% ± 12.8 (low actionability). The mean Flesch-Kincaid reading ease score was 32% ± 25.7, and the mean Simple Measure of Gobbledygook index readability score was 15.3 ± 9.1(indicating poor readability for the lay person). Misleading and false information were detected in some answers.

Conclusion: ChatGPT has significant potential as a tool for answering parent's questions about ECC. Concerns, however, do exist about the readability and actionability of the answers. The presence of false information should not be overlooked.

Background: The main goal of the nasoalveolar molding (NAM) is to mitigate the initial severity of the cleft, facilitating the subsequent surgical procedures. Nevertheless, the use of the appliance entails high stress levels for families.

Aim: The aim of this study was to assess the perceptions, attitudes, and opinions of parents whose cleft-affected children underwent treatment using the NAM technique.

Design: A cross-sectional questionnaire study was conducted on a cohort of relatives of infants born with cleft lip and palate who were treated with the NAM appliance. The parents completed a 59-item questionnaire that had been previously validated.

Results: The initial cohort consisted of 104 families. The level of satisfaction was high, and there was a direct correlation with early diagnosis. Satisfaction levels varied depending on the cleft type, with a decrease in cases of bilateral presentation. Satisfaction was influenced by the newborns' adaptation and the absence of complications. Parents who exhibited lower levels of satisfaction contemplated terminating the treatment.

Conclusions: Parents expressed high satisfaction with NAM treatment, due to effective management and understanding. Bilateral clefts and delayed diagnosis can significantly impact satisfaction. These results emphasize the importance of personalized approaches to address challenges in NAM treatment, particularly in instances of bilateral clefts and delayed diagnoses.

Background: Dental radiography is an essential diagnostic tool in paediatric dentistry.

Aim: To explore attitudes, knowledge, and related factors of paediatric dental radiography among parents who attended the radiology department of a premier public dental hospital.

Design: The study was conducted at the National Dental Hospital (Teaching) Sri Lanka among 124 parents whose children (<13-years) underwent dental radiographic examination. Data on sociodemographic characteristics, radiographic investigations, and parental knowledge and attitudes on paediatric dental radiography were collected using an interviewer-administered questionnaire. Data were entered and analyzed using the SPSS-21 statistical software package.

Results: The mean score (95% CI) of parental attitudes and knowledge on paediatric dental radiography were 17.55 (17.64-18.45) on a scale from 7 to 35 and 3.73 (3.34-4.13) on a scale from -7 to +7, respectively. Significant differences in parental knowledge were evident by child's age (p = 0.046), ethnicity (p = 0.035), and parental attitudes (p = 0.024). Binary logistic regression analysis revealed a significant independent association between parental attitudes with parental knowledge: OR (95% CI) = 2.413 (1.098-5.302) (p = 0.028).

Conclusions: Parents demonstrated less favorable attitudes but sufficient knowledge on many aspects of paediatric dental radiography. Therefore, interventions are needed to improve parental attitudes on paediatric dental radiography especially by providing child-friendly services.
