The relationships between malocclusion, gingival inflammation, plaque and calculus.
Certain features of malocclusion considered important in relation to periodontal health were analyzed in a study of 300 subjects. It was found that plaque and gingival inflammation were not related to vertical incisor overbite, horizontal incisor overjet or posterior cuspal interdigitation. Individual tooth irregularity measured as tilting, rotation, displacement and crowding had a low but statistically significant correlation with plaque, calculus and gingival inflammation. However, the study showed that these features of malocclusion are far less important than the extent of plaque and calculus deposits in the development of gingival inflammation.
