The purpose of this study was to determine which factors related to patient self-assessment of dentures are associated with changes in oral health-related quality of life (OHRQoL) among edentulous patients after replacement of complete dentures, and to determine whether masticatory performance as determined using an objective method affects the changes in OHRQoL among edentulous patients. As a preliminary study, the existing questionnaire regarding self-assessment of dentures consisting of 39 question items, measured with a 100-mm visual analogue scale, was analysed by factor analysis. Then a questionnaire, composed of 22 question items, was developed containing six subscales of 'function', 'lower denture', 'upper denture', 'expectation', 'aesthetic and speech' and 'importance'. ⋯ The questionnaire and measurement were completed twice; before and after replacement of complete dentures. Stepwise multiple regression analysis identified 'lower denture' and 'aesthetic and speech' as significant independent variables besides OHIP-EDENT scores before replacement. These results suggest that sufficient retention of lower dentures and appropriate appearance may lead to improved OHRQoL in edentulous patients.

Randomized Controlled Trial Comparative Study
Efficacy of stabilisation splint treatment on temporomandibular disorders.
The evidence supporting the use of stabilisation splints in the treatment of temporomandibular disorders (TMD) is scarce and a need for well-controlled studies exists. The aim of this randomised, controlled trial study was to assess the efficacy of stabilisation splint treatment on TMD. The sample consisted of 80 consecutive referred patients who were randomly assigned to the splint group (n = 39) and the control group (n = 41). ⋯ Facial pain decreased and most of the clinical TMD findings resolved in both of the groups. The differences in changes in VAS or clinical TMD findings between the groups were not statistically significant. The findings of this study did not show that stabilisation splint treatment in combination with counselling and masticatory muscle exercises has additional benefit in relieving facial pain and increasing the mobility of the mandible than counselling and masticatory muscle exercises alone in a short time-interval.
