Method: The study will recruit 39 subjects who received RPD at Department of Prosthodontics, Taipei Medical University Hospital. The oral hygiene (plaque index, PI) and periodontal condition (pocket depth, PD; gingival index, GI) were also assessed. The pH value, flow rate and buffer capacity of saliva were estimated through the collected saliva of patients by chewing a block of paraffin wax for three minutes. Specimens of saliva were assessed in measuring glass for flow rate determination and examined on test strips for pH vale and buffer capacity assessment. Besides, the saliva was centrifuged and extracted for total antioxidant status (TAS) and superoxide dismutase (SOD) measurement with commercial kit and ELISA reader. The patients’ satisfactions with prosthetic treatments were estimated via the oral health impact profile (OHIP).
Result: The analyzed data indicated that the edentulous condition was not significantly related to the OHIP, however the PI status of patients was significantly related to the domain of psychological disability (p <0.05) and the domain of social disability (p<0.01) in OHIP. The GI status of patients was significantly related to the domains of physical pain, physical disability, and psychological disability in OHIP (p <0.05). The buffer capacity of saliva was significantly related to the domains of functional limitation and psychological disability in OHIP (p <0.05). The SOD of saliva was significantly related to the domains of psychological discomfort and handicap in OHIP (p <0.05).
Conclusion: The results meant that if the less value of PI/GI/SOD or the more buffer capacity the partially edentulous patients had the better patients’ satisfactions and prognosis of prosthetic treatment the dentists could expect.
