Assessment of Discomfort Experienced by School Children While Performing  ART and  MCP -An Experimental Study

Atraumatic Restorative Treatment (ART) is a minimal intervention technique in the management of carious lesions, which results in negligible dis-comfort to the patient. The aim of this study was to assess and compare the dis-comfort levels during Atraumatic Restorative Treatment and Minimal Cavity Preparation (MCP: a method using rotary instruments) treatment procedures in a sample of school children in Davangere city. An experimental study was performed aimed at com-paring discomfort levels as measured by subjective (Venham index) and objective (Heart rate) methods at six specified moments during the treatment. A total of 200 children were randomly divided into two groups of 100 each. In each child, one class II restoration with GIC in a deciduous molar was performed. One group re-ceived treatment using rotary instruments (MCP) and the other group with ART. Discomfort levels were measured using Venham index (behavioural dimension) and heart rate (physiological dimension). The behavioural measurement revealed that in ART group the majority of the children(64%) showed an overall Venham score of „<1‟(relaxed) as com-pared to MCP group in which the majority of children (76%) showed a Venham score of „1‟(uneasy). The physiological measurement revealed that the children in ART group experienced less discomfort when compared to children in MCP group. The results of the study suggest that ART induces less discomfort; is patient friendly and has a higher extent of community acceptance when compared to MCP.
