title: [Influence of the removable partial denture acrylic resin on oral health and quality of life].
abstract: OBJECTIVE
  This study aims to evaluate dental decay incidence and DMF index, plaque index and gingival index, and to assess the satisfaction/dissatisfaction in acrylic removal partial denture wearers (ARPD) and in partial edentate no wearers. It aims to improve the therapeutic management in prosthetic oral rehabilitation in DR Congo.
  
  
  METHODS
  This prospective cohort interventional randomized study on 376 patients enrolled and divided into two groups (with and without denture prosthesis) was performed in University Clinics of Kinshasa, Kinshasa Medical Center and Clinic Glory during the period August 2008 to August 2010.
  
  
  RESULTS
  Three hundred seventy-six patients (376) with 163 men (47 ± 16 years) and 213 women (42 ± 15 years) were followed. Of the 376 patients randomized, 189 were of "prosthesis" group and 187 were in the group "without aid". Both groups were regularly reviewed every 6 months for 2 years. Ten thousand four hundred and fifty-two (10452) teeth were examined (5149 teeth to the group "prosthesis" and 5303 for the teeth "without prosthesis" group. On hundred and twenty-nine (129) teeth that presented caries, 110 (82.96 per cent) are decayed teeth in the "prosthesis" group and 19 (17.04 per cent) are in the group "without prosthesis" (p = 0.00). The index Tooth Decayed, Missing, Filled (CAD) to start of the study for each group was 0.2. Two years after the index rose to 0.3 for the group "prosthesis" and remained steady (0.2) for the group "without prosthesis". The "prosthesis" group showed plaque index (PI) and gingival index (GI) above 0.99 (SD: ± 0.28) and 1.27 (SD: ± 0.43) than normal compared to those of the "no aid" group (0.46 ± 0.15 and 0.32 ± 0.12). The differences were statistically significant for both indices between the two groups (p = 0.00). Overall satisfaction rate for the "prosthesis" group was 26.4% while for the group "without prosthesis" satisfaction rate is 80.9%.
  
  
  CONCLUSIONS
  This study shows that improved oral hygiene and regular check of the RPD acrylic resin carriers become a concern for establishing a true oral health policy.
