Facet pattern in intact and restored dentitions of young adults a comparative study

Abstract

The attritional dental pattern was studied clinically and on plaster casts in a group of individuals, 17-22 years old, with intact teeth and in a control group with a 'normal' distribution of dental restorations. The following observations were made: 1) all contact areas between occluding teeth exhibited facets; 2) most facets were located on inclines; 3) facets in the fossa bottom occurred oftenest in the control group and often involved fillings; 4) attritional facets on the distal marginal crest of the lower second molars were oftenest found in the control group; 5) denuded dentin in facets occurred oftenest in the control group; and 6) the number of facets and the worn areas were on an average largest in the control group. The findings in this study indicate a difference in the functional activity between the groups and support the hypothesis that dental fillings can induce changes in the neuromuscular pattern of the masticatory system.

Three-year longitudinal study of mandibular dysfunction in young adults with intact and restored dentitions

“…In accordance with previous studies of adolescents with and without dental fillings (6)(7)(8), the subjects in group C had a higher prevalence and degree of mandibular dysfunction than those in group I. The difference between the groups was almost the same as at the examination 3 years earlier.…”

“…However, the controversy about the relative importance of different etiologic factors, including occlusal ones, still exists (4, 5). Kampe et al (6)(7)(8) recently found more signs and symptoms of mandibular dysfunction in subjects with restored dentitions than in those with intact teeth. They suggested, as an explanation for their findiqgs, that dental fillings might induce neuromuscular changes in the masticatory system.…”

Five‐year longitudinal study of adolescents with intact and restored dentitions: signs and symptoms of temporomandibular dysfunction and functional recordings

“…Together with the finding of more parafunctions in group F, more attrition in the lower molars, more muscle tenderness and more frequent pain on movement of the mandible among the subjects in groups FI and F are indicative of more muscular hyperactivity in subjects with restored dentitions. The aetiology of TMJ disorders is controversial (Rugh & Orbach, 1988), but the findings in this and previous studies (Kampe et al, 1983a(Kampe et al, , 1984(Kampe et al, , 1991 indicate that dental filling therapy has a possible aetiological significance.…”

Avaliação clínica dos fatores etiológicos das lesões cervicais não cariosas

“…Optou-se por uma dupla avaliação dentária (intraoral e modelos), por ter-se verificado que o uso de modelos permite o acesso mais detalhado das superfícies oclusais e um nível maior de identificação das facetas de desgaste do que somente a inspeção intraoral (KAMPE; HANNERZ; STRÖM, 1984;FAREED;OMAR, 1990;JOHANSSON et al, 1993).…”
