OBJECTIVE: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption.
STUDY DESIGN: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group 'A'- 47 canals with collagen barrier (Test group) and Group 'B'- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed. Pearson's chi - square test was applied to analyze the results. The significance level was predetermined at p < 0.05.
RESULTS: Among the test group, 93.6% of the canals showed no extrusion while, 6.4% showed visible extrusion of the material outside the apex. In the control group, 83% showed no extrusion whereas 17% of the canals showed visible extrusion outside the apex. But no significant difference was noted (p>0.05).
CONCLUSION: The placement of resorbable collagen barrier in the apical third of the canal prevented the extrusion of obturating material beyond the apex in resorbing primary molars.
