Comparative Evaluation of Reduction in Pain Perception Using 5% Topical LA vs Freezed Cone as a Preparatory Agent for Intraoral Injection in Children and Effect of VRD as Distraction Technique.

Aim: To compare freezed cone and 5% lignocaine as a numbing agent before intraoral injection and evaluate the effect of virtual reality distraction (VRD) as a distraction technique in reducing pain perception in children. Study design: Around 60 children of 6-11 years old undergoing treatment for the extraction or any pulp therapy of primary tooth were selected. Freezed cone and 5% lidocaine were used to decrease the pain during local anesthesia (LA). VRD was used as a distraction method and to analyze the pain perception, Wong-Baker Faces Pain Rating Scale was used. Materials and methods: Each child was randomly assigned to receive ice as a topical anesthetic or lignocaine 5% as a topical anesthetic agent. The pain perception was evaluated after the injection of 2% lignocaine hydrochloride (HCL). The primary researcher evaluated the pain during injection using the sound, eye, motor (SEM) scale. The pain experienced during injection was evaluated using Wong-Baker Faces Pain Rating Scale. Results: In the freezed cone group with the VRD technique, maximum responded to the less pain score. On the contrary, many responded to higher pain scores in the freezed cone group without the VRD technique. Conclusion: It was concluded that the VRD technique can be used for distraction and the frozen ice cone can be an alternative method to reduce the pain perception during LA.

Efficacy of Silver Diamine Fluoride on Streptococcus mutans Count Present in Saliva.

AIM AND OBJECTIVE: Evaluate the efficacy and longevity of silver diamine fluoride (SDF) to inhibit the dental caries initiator bacteria; Streptococcus mutans count in saliva. STUDY DESIGN: Twenty children having class I and II dental caries with no prior restorations were included in the study. Unstipulated saliva samples were collected before and immediately after application of SDF, 1, 3, and 6 months after application, and intergroup comparison was done. MATERIALS AND METHODS: Silver diamine fluoride was applied on the cavitated surfaces with microbrush tip under isolation, then wait for 4 minutes and washed away all surfaces with water spray. Saliva was collected in a sterile saliva collection tube and sent for microbiological culture assessment. CFU/mL of S. mutans count was done with the Digital colony counter. For statistical analysis, paired T-test was performed. RESULTS: Silver diamine fluoride showed a significant drop in CFU/mL of S. mutans count at 1 month then 3 and 6 months accordingly. CONCLUSION: Silver diamine fluoride can be used to prevent and arrest dental caries and the best result can be achieved by quarterly application.

Deciduous Mandibular Second Molar with Supernumerary Roots and Root Canals Associated with Missing Mandibular Permanent Premolar.

Morphological variations like additional roots and root canals in human deciduous dentition are rare. Knowledge of the morphology, variation of root and root canals of deciduous teeth are useful for successful endodontic treatment and exodontia. Presented here is a case report of the supernumerary roots and additional root canals of deciduous mandibular second molar (85) with congenitally bilateral missing of mandibular permanent second premolar (35 and 45) tooth bud.
