Overview

Cross-sectional study shows occlusal contact differences impact tooth microstrain in mandibular molars, indicating potential dental issues.

Key Points

  • This research aims to explore the effects of occlusal contact locations on microstrain in mandibular molars.
  • Conducted a cross-sectional study with 29 participants aged 20 to 40 years.
  • Utilized strain gauges to evaluate coronal microstrain after bite load applications.
  • Categorized groups based on functional and nonfunctional cusp contacts.
  • Measured occlusal bite force using Tekscan B201 FlexiForce sensor and T-Scan 10 Novus for distribution assessment.
  • No significant differences in occlusal bite force between test and control groups (p = 0.96; 0.09).
  • Lingual coronal microstrain was significantly lower in the control group compared to buccal microstrain (p = 0.001).
  • Test group exhibited higher lingual coronal microstrain than the control group (p = 0.001).
  • No significant difference in buccal microstrain between groups (p = 0.111).
