Evaluation of changes in the occlusion and occlusal vertical dimension in children following the placement of preformed metal crowns using Hall technique

Hall technique involve restoring  decayed primary molars by cementing a stainless steel crown on the affected tooth without any tooth preparation.This technique has gained more popularity in the recent years as it minimises child discomfort in the dental operatory.It also improves restoration longevity as suggested by the studies condunted on this technique. Since occlusal reduction is not done while restoring primary molar a raise in the bite will be present after crown placement using this technique which is of some concern.The purpose of this study is to evaluate this occlusal changes following this technique in 44 children for one month.
