| Abstract: | In the present study the association between the occurrence of retained roots and several oral status factors was studied using a representative sample of 8,000 Finnish adults 30 yrs of age and over. The overall prevalence rate of dentate subjects with roots was 21%, a rate consistently higher among men. In the age category 65+ yrs, the prevalence rate was 35%. Among subjects with at least one root the average number of roots was 2.7. Those having removable denture(s) and a number of filled teeth showed a decreased probability of having root(s). Among those having root(s) the greater number of roots was associated with increasing age and with increasing number of remaining and decayed teeth. |
