Method: A questionnaire was sent to 2244 individuals randomly selected from the national register in the County of Dalarna Sweden in 2012 of whom 1375 (62 %) responded. The questionnaire contained of 74 questions, 9 questions originated from the Oral Impact on Daily Performance (OIDP). OIDP measures the frequency of problems related to the oral cavity and the response rate is a 5-point Likert-scale from “no problems” (=1) to “problems every, or almost every day” (=5). A summary of the responses produces an overall score ranging from 9 was (best possible) to 45 (worst possible). In total 1132 individuals, 53 % women and 47 % men (mean age 58), underwent a clinical examination including dental caries and periodontal status, number of teeth and Temporomandibular Disorders (TMD).
Result: Sixty-nine present (69 %) did not report any impact on OHRQoL (OIDP =9). One person reported worst possible OHRQoL (OIDP =45). The mean value for OIDP was 10.3 (sd 3.3). The mean number of teeth was 25.0 (sd 6.6), mean DS 1.1(sd 3.5), mean DT 0.7 (sd 1.6), mean number of teeth with PPD ≥ 6 mm was 0.7 (sd 1.9). Sex percent (6%) reported some kind of TMD. Individuals with less number of teeth, decayed teeth and surfaces and TMD reported worse OHRQoL. There were no association between periodontal variables and OIDP.
Conclusion: Individuals with dental caries and TMD reported greater Oral Impact on Daily Performance compared to those without dental caries and TMD.
