Sažetak
The principal study objective was to define causative relation between
masticatory forces and pathological abrasion. Gnathodynamometric
measurements were made in 30 males aged from 30 to 75 years aged from 30 to 75 years with marked clinical signs of pathological abrasion, and in control subjects (n = 50) comprising young males aged from 18 to 22 years. The mean value o f masticatory force intensity in subjects with abrasion in the right segment o f the jaw was 391 N, while in the control group it was 496 N (t--3.41; p-0.001). The mean value o f intensity of masticatory forces in the anterior segment of the jaw in subjects with pathological abrasion was 282 N and 336 N in the control group (t=-2.27; p=0.026). The mean value of masticatory force intensity in subjects with pathological abrasion in the left segment of the jaw was 388 N and 462 N in the control group (t--2.27; p-0.026). In the group of subjects with abrasion inversely proportionate statistically significant correlation was found between the intensity of masticatory force and loss o f a tooth on the same side. Masticatory forces in subjects with parafunctions have shown to be greater than in other study subjects.The obtained results contribute to knowledge on the significance of masticatory forces in the development o f abrasion, which is o f utmost importance in all fields of dentistry.
