The Hall technique as a minimally invasive treatment for caries lesions. Literature review.

Abstract

Introduction: The Hall technique was developed in 2006 by Dr. Norna Hall as a minimally invasive alternative for dental treatment in children to eliminate the use of conventional protocols. Problem statement: The treatment of caries lesions generates anxiety in children, due to the use of local anesthesia and hand-piece, so less invasive but effective alternatives should be sought. Objective: Establish the indications of the Hall technique as a minimally invasive treatment for caries lesions in primary dentition. Literature review: The Hall technique consists of sealing the caries lesion by cementing preformed metal crowns without prior preparation, so it does not require the application of local anesthetic or hand-piece. The purpose is to stop the progression of the condition, isolating the injury from the oral environment. It is indicated in primary molars with occlusal and/or proximal lesions without pulp involvement. There is controversy due to the increase of the vertical dimension, but it has been proven that in 3 or 4 weeks the occlusion returns to normal ranges. Several studies reveal that it has a success rate of 95% to 98% and has a high acceptance by patients and their parents. With the appearance of COVID-19 it is a great option as it does not generate aerosols. Conclusions and recommendations: The use of the Hall technique simplifies rehabilitation in the primary dentition, but it must be supported by a correct pulp diagnosis in order to be successful.
