Effect of Different Patterns of Molar Teeth Extraction on Memory in Rats: A Short Report

Background and Objectives: Tooth extraction is one of the ways to treat dental diseases. The aim of this study was to determine the effect of different molar tooth extraction patterns on short-term and middle-term memory in rats. Materials and Methods: In this experimental study, 45 male Wistar rats were divided into three groups: control group (C) without pulling, pulling group 1 (E1) by pulling bilateral maxillary molars, and pulling group 2 (E2) by pulling the left maxillary and right mandibular molars. The Maurice Watermase test was performed to assess spatial memory. Tukey’s test was used to analyze the data. Results: In short-term memory tests, the number of visits to the target area was significantly lower in group E1 than in group C (p=0.003). In group E2, the time spent in the target area and the distance traveled in the target area was longer than group E1. Conclusion: This study explained that the molar teeth extraction may impair the memory ability.
