Efetividade do tratamento com próteses totais convencionais em idosos: ensaio clínico controlado e randomizado. 2019. 82f.

A total of 50 participants were randomized into two groups: control group (CG; old CDs evaluated at T0 and reassessed after 3 months - T1; n = 25) and test group (TG; old CDs evaluated at T0 and new CDs evaluated after 3 months of use; n = 25). The MP was analyzed by determining the median particle size (X50). OHRQoL was obtained from the OHIP-Edent Questionnaire and satisfaction was assessed through functional and psychological criteria using a previously validated questionnaire. TQ was obtained by a clinical evaluation regarding technical factors related to the dentures, such as anterior teeth arrangement, retention and stability. Depending on the normal distribution of data, parametric and nonparametric tests were used in the statistical analysis (95% confidence interval). The final sample consisted of 48 older adults, with a mean age of 68.77 years (± 6.01), predominantly female. The MP for the CG was significantly better than the TG at T0 (p = 0.024). However, at T1, the groups were similar, with an approximate X50 of 6.7 mm. In the CG, the X50 increased 0.21mm from T0 to T1; and the TG showed a small reduction of -0.02 mm. There was no significant difference between the groups regarding the variation of X50 (p = 0.105). For the TG, the total OHIP-Edent median decreased significantly after treatment (from 12.00 points to 5.00; p = 0.001). This reduction was significant for the following domains: masticatory-related complaints (p = 0.010), oral pain and discomfort (p = 0.014) and psychological discomfort and disability (p = 0.003). The variation in satisfaction means increased significantly only in the TG, from 59.04 to 93.82 points (p <0.001). Similarly, for the test group, TQ also presented a positive variation of 55.00 points (p <0.001). Taken together, these findings suggest that new bimaxillary conventional CDs promote a significant improvement in the OHRQoL, satisfaction and TQ among older adults. However, it did not improve the masticatory performance when a 3 months period of use was considered. Nonetheless, conventional CDs are still considered viable for the older adults. As a suggestion for future studies, a longer adaptation period for the new dentures should be evaluated as well as effectiveness of replacing old CDs related to the nutritional condition of the patients.Acesso AbertoMastigaçãoPrótese totalIdosoSatisfação do pacienteArcada edêntuladoctoralThesisCNPQ::CIENCIAS DA SAUDE::ODONTOLOGIA
