Comparison of clinical performance of newer chemo-mechanical caries removal system and conventional cavity preparation technique in children

Objective: The study was aimed to compare the clinical performance of newer chemo-mechanical caries removal system and conventional cavity preparation technique in children. Study Design: Forty primary molars or first permanent molars of twenty children between the age groups of seven to ten years were selected randomly and divided into two groups of twenty teeth each: Group I was treated by the mechanical method and Group II with Brix 3000 gel method. The efficacy, time taken, and the pain threshold were evaluated during the caries removal by Ericson D et al. scale, stopwatch and modified visual analog scale, respectively. The preferred choice of treatment was assessed using a questionnaire. Results: The comparison between the time taken by the two methods showed a significant difference (P < 0.05). The caries removal efficacy indicated a significant difference as well ( P < 0.05). The pain rating results indicated a notable difference in the mean Visual Analogue Scale score (P = 0.001). The comparison between the two choices of treatment indicated a significant difference at p≤0.05. Conclusion: It was concluded that airotor was efficient in caries removal and while Brix 300 had lower pain rating and better patient acceptance

Dentigerous cyst enucleation: A conervative approach

Dentigerous cyst is a type of odontogenic cysts and generally occurs in the ages of twenties or thirties. Dentigerous cyst always includes a tooth which cannot complete the eruption process and occurs around the crown by the fluid accumulation between the layers of enamel organ. In rare cases, dentigerous cyst occurs in the first decade of life and develops in an immature permanent tooth as a result of a chronic inflammation of overlying nonvital primary tooth. In this report, a case of dentigerous cyst in primary dentition in a 9-year-old child patient and its treatment were presented. The standardized treatment for a dentigerous cyst is enucleation and extraction of the involved tooth. In cases of larger cysts, an initial marsupialization to diminish the size of the osseous defect, followed by enucleation and tooth extraction, has been advocated. However, if the patient is a child and the cyst is small, removal of cystic lining followed by extraction of deciduous tooth usually results in disappearance of the cyst and preservation of the permanent tooth. When dealing with larger lesions, enucleation and tooth extraction have been favored. This can lead to functional, cosmetic, and psychologic consequences for the child
