A Comparative Evaluation of Separation Effect and Perception of Pain using Two Different Orthodontic Separators

Abstract

Objective: To compare the time taken to achieve adequate separation of tooth contact and perception of pain associated with it using elastomeric and spring separators. Materials and methods: A total of 60 subjects (30 males, 30 females) in the age range of 18 to 25 years were divided into three groups with 20 subjects each (10 males and 10 females). Group 1, 2 and 3 were evaluated after 1, 2 and 3 days of separator placement respectively for the degree of separation and pain perception. Two types of separators namely elastomeric and spring separators were placed, at the mesial and distal contacts of the first permanent molars in the maxillary and mandibular arches. The amount of separation at each contact point was measured with the help of the feeler gauge and discomfort level was recorded on verbal rating scale. Results: Both types of separators achieved adequate separation after 2 days of separator placement. There was no genderwise difference in the amount of separation and time taken for separation as well as pain perception with either of the separators. The intensity of pain remained mild-to-moderate on VRS scale scoring 2 to 3 with either of separators. The pain was worst after 2 days of separator placement and declined after 3 days irrespective of the type of separators. Conclusion: Both types of the separators are comparable for separation effect and pain perception associated with them. Molar band fitting should be done at least 3 days after inserting either of the separators.
