ABSTRACT
Objective@#To explore the relationship betweenrheumatoid arthritis (RA) and chronic periodontitis (CP). @*Methods@# A total of 48 RA patients were recruited from the Rhematology Department of The First Affiliated Hospital of Shantou University Medical College (SUMC). RA patients were matched on age and gender with healthy controls, who were recruited from the Stomatology Department. Dental parameters including unstimulated salivary flow rate(UWS), stimulated salivary flow rate (SWS), bleeding on probe (BOP), periodontal probing pocket (PD), clinical attachment level (CAL) and decayed, missing and filling (DMF) were recorded in all cases. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and Anticyclic citrullinated peptide antibody (Anti-CCP) were also recorded in RA patients. @*Results @#There were significant difference between RA group and health control group on salivary flow rate, BOP, PD, CAL and DMF (P< 0.001). Higher percentage of RA patients were diagnosed as periodontal disease than those in control group (P< 0.001). There was relationship between CAL and Anti-CCP antibody (P< 0.001). @*Conclusion @# RA patients have higher risk of CP, and there might be relationship between RA and CP.
ABSTRACT
OBJECTIVE: To translate the original English version of oral health impact profile (OHIP)-14 into Chinese version and to test the psychometric properties of the Chinese version for use among the Chinese adults. METHODS: The original English version of OHIP-14 was translated into Chinese, and pre-tested and cross-cultural adapted. Subsequently the Chinese version with a general questionnaire was administered to adults aged 18 approximately 65 years by a trained interviewer. Reliability of the translated scale was assessed in terms of internal consistency using Cronbach's alpha and corrected item-total correlation. Construct validity was evaluated by factor analysis and criterion-related validity was evaluated by examining the associations between perceived oral health status, perceived need for dental care and OHIP-14 scores. Formal psychometric properties were tested according to the standard procedure of the international quality of life assessment (IQOLA) project. RESULTS: A total of 592 adults were surveyed. There were 550 valid questionnaires involving 38 ones with missing data. Cronbach's alpha of the translated scale was 0.93, corrected item-total correlation ranged from 0.53 to 0.71. The 14 items were divided into four domains. There was certain logical relation between the items in the same domains. There was highly significant association between perceived oral health status, perceived need for dental care and OHIP-14 scores. CONCLUSIONS: The translated Chinese version of OHIP-14 demonstrated good reliability and validity. Its good psychometric properties provide the theoretical evidence for further use in Chinese population. It is available for use by researchers in oral health related quality of life studies in Chinese adults.
