| Research Abstract |
The purpose of this study was to investigate the effects of Sleep Bruxism (SB) and Tooth Contacting Habit (TCH) on periodontal sensation.Thirty subjects divided into four groups representing G1 (SB+, TCH+), G2 (SB+, TCH-), G3 (SB-, TCH+) and G4 (SB-, TCH-). Periodontal sensation was assessed based on interocclusal tactile threshold (ITT) in the first molar region. The ITT was not significantly different between each group. The ITT of SB subjects (G1 and 2) were significantly lower than that of non-SB subjects (G3 and G4) (p < 0.01). On the other hand, the ITT of TCH subjects (G1 and G3) was not significantly different from that of non-TCH subjects (G2 and G4).
The results of this study suggest that SB affects periodontal sensation but TCH dose not affect periodontal sensation.
