The Effectiveness of Cognitive-Behavioral Intervention on Dental Anxiety during Pulpotomy in 7-10 Year-Old Children: A Clinical Trial.

Objectives: Dental anxiety is a common phenomenon experienced by children in the dental setting. However, there is limited research on the effectiveness of cognitive-behavioral interventions in managing this anxiety. Therefore, the aim of this study was to evaluate the impact of a cognitive-behavioral psychologic intervention on dental anxiety in children. Materials and Methods: A total of thirty children, aged 7-10 years, underwent prophylaxis and fluoride therapy. The baseline anxiety levels of the children were determined using the Modified Child Dental Anxiety Scale (MCDAS). The intervention group (N=15) received two 30-minute sessions of cognitive-behavioral exercises. Additionally, a short film demonstrating a cooperative child undergoing pulpotomy was created and parents were instructed to show it to their children at home. During the treatment session, the exercises were reinforced at each step, and the MCDAS questionnaire was administered again. The children's behavior was also assessed using the Venham Clinical Cooperation Scale. Independent t-test, Mann-Whitney, chi-square, and Pearson's correlation coefficient were used for statistical analysis and P<0.05 was considered statistically significant. Results: Postoperatively, the MCDAS score in the intervention group was significantly lower compared to the control group. Notably, the intervention group demonstrated a downward trend in anxiety scores, while the control group showed an increase (P<0.001). Conclusion: Cognitive-behavioral interventions were found to be successful in decreasing dental anxiety in children undergoing pulpotomy. These interventions can be successfully implemented in clinical settings.

Barriers and Drawbacks of the Assessment of Dental Fear, Dental Anxiety and Dental Phobia in Children: A Critical Literature Review.

OBJECTIVE: Dental anxiety, fear and phobia have different etiology, response patterns, time courses, and intensities that justify a clear distinction between these constructs. Differentiation of dental anxiety, fear or phobia in practice is a critical prerequisite for developing and implementing effective treatment for children. The aim of this study was to investigate whether current researches in the pediatric dentistry appropriately discriminate the central construct of dental anxiety, fear and phobia. We also highlighted the specific methodological issues in the assessment of these issues in pediatric dentistry. STUDY DESIGN: A systematic search was conducted in Pubmed/medline and Scopus for articles which assessed dental anxiety, fear or phobia in children. RESULTS: 104 research papers were included in the review that had made a distinction between dental anxiety, fear and phobia and had not used them interchangeably. Only five studies used different clinical measures or cut-offs to discriminate between dental anxiety, fear and phobia. CONCLUSION: The dental literature appears unable to capture and also measure the multi-sided construct of dental anxiety, fear and phobia and, therefore, there was a tendency to use them interchangeably.

Impact of Chlorhexidine Pretreatment Followed by Probiotic Streptococcus salivarius Strain K12 on Halitosis in Children: A Randomised Controlled Clinical Trial.

PURPOSE: The aim of this study was to examine the effect of chlorhexidine disinfection, as a chemical method of oral hygiene practice, and subsequent use of probiotics on halitosis in children. The effects of mechanical and chemical oral hygiene practice methods on the severity of halitosis were also assessed. MATERIALS AND METHODS: 208 children with organoleptic test (OLT) scores of 2 or more were randomly assigned to four groups: A: conventional oral hygiene practices (COH) including toothbrushing and flossing; B: COH + tongue scraping (TS); C: COH + TS + chlorhexidine; D: COH + TS + chlorhexidine + probiotics. OLT was performed at 1-week and 3-month follow-ups. RESULTS: A significant and stable number of participants showed major and moderate levels of improvement in OLT scores in group D (p < 0.001). The improvement of OLT scores in group C was also significant (p < 0.001), but not stable over the follow-ups (p = 0.44). Neither significant nor stable improvements in the OLT scores were detected in groups A and B through follow-ups (p > 0.05). CONCLUSION: Probiotic therapy following oral disinfection with chlorhexidine may reduce the severity of halitosis over longer periods.

Class III Restoration of Anterior Primary Teeth: In Vitro Retention Comparison of Conventional, Modified and Air-abrasion Treated Preparations.

Background and aims. Anterior esthetic restoration is challenging in pediatric dentistry, due to limited durability and poor retention of the restoration.This study assessed the effect of air abrasion on tensile failure load of composite class III restorations using different preparation techniques. Materials and methods. 100 extracted human anterior primary teeth were divided, based on the preparation methods, into four groups each consisting of 25 subjects : conventional (A), labial surface bevel (B), conventional + air abrasion (C), and labial surface bevel + air abrasion (D). After restoring cavities, tensile failure load of samples was measured in Newton by Universal testing machine at a crosshead speed of 1 mm per minute. The data were analyzed by Kruskal-Wallis and Mann Whitney U tests using SPSS software. Results. There were statistically significant differences between groups A and C (P = 0.003), groups A and B (P & 0.001), groups A and D (P & 0.001), groups B and C (P = 0.028), groups B and D (P = 0.027), and also groups C and D (P& 0.001). Group D demonstrated the highest mean tensile failure load. Conclusion. Labial surface bevel treated by air abrasion showed significantly more retention of composite restoration.
