Play is an inseparable part of childhood and can act as a mode through which children can be desensitized toward dental treatment. Aim: To assess and compare the efficacy of bubble breath play therapy (BBPT) and tell-show-do (TSD) technique in the dental management of anxious/fearful children. Materials and methods: Forty-eight children aged 6–8 years were randomly divided into group I: BBPT and group II: TSD. The effectiveness of the BBPT and TSD technique in reducing anxiety/fear in children was assessed pretreatment, during, and posttreatment evaluation of the child's anxiety levels using finger pulse oximeter and Venham's anxiety and behavior rating scale. All children underwent rotary restorative treatment. Results: The mean pulse rate in the BBPT and TSD group was 106.96 mm Hg and 102.25 mm Hg, respectively, at baseline. A decrease in the pulse rate was observed in both the groups after the application of behavior modification strategies. However, after the dental treatment, the mean pulse rate slightly increased in the BBPT group, while it showed a further improvement in the TSD group. Conclusion: The BBPT acts as a distraction and can be considered to enhance rapport between the dentist and children during dental treatment. Clinical significance: Application of appropriate strategies to allay dental fear in children is essential to provide quality dental treatment and build a positive attitude toward oral health.
