Reverse Band And Loop - When And Where To Give???

One of the most important factors involved in preventive and interceptive dentistry is the preservation of the primary dentition until the normal time of exfoliation. In the absence of the primary second molar, mesial movement and migration of the permanent molar may occur prior to and during eruption.Even when the prognosis is in doubt, root canal treatment of the infected primary second molar allows the first permanent molar to erupt fully into its normal position after which the second molar can be removed and an appropriate space management technique initiated. followed pulpotomy and pulpectomy treatment of primary molars, with some possible deflection in the eruption path. Coil et al. (1985) described 41 nonvital root canal treatments of primary molars in 37 children and reported success to be 80%.Coll and Sadrian, in a retrospective study of pulpectomy outcomes, noted two parameters that were the highest predictors of success. Pretreatment pathologic root resorption, when evident, resulted in a 44.4% prevalence of enamel defects in underlying permanent teeth after their eruption. In the absence of pretreatment pathologic root resorption, the pulpectomy success rate was
