This study is to assess the oral health related impacts on the quality of life and
factors associated with the quality of life in the elderly population after complete denture
delivered at dental department, Ratchaburi Hospital year-2011. The quality of life between
those who had and had not a revisit were also compared. The study design was a
retrospective longitudinal with a total of 104 participants attending the complete denture
program carried by researcher. Quality of life was assessed by an interview for the OIDP
index (Oral Impacts on Daily Performance) in 104 participants. Seventy eight participants
(75 percents), who had revisited at the dental department were directly interviewed, while
the remaining 26 (25 percents), who failed to do so, were interview by telephone. The
OIDP index was calculated by frequency and severity of oral disorders impacts effecting on
8 daily routine activities. Values of OIDP index range from 0-100. The result was shown that
the age of the participants ranged from 60-85 years old. The quality of life in the majority
of them (79.4%) having complete denture was in a good to very good level (OIDP
index<0.6). Almost 70% of them had no oral problem (OIDP=0), with a very good quality of
life, whereas the remaining had at least one difficulty. Two most common difficulties were
eating (29.8%) and speaking (18.3%). The poor prognostic factors significantly affected the
quality of life were younger aged (p-value = 0.030), low income (p-value=0.029), and the
residual teeth (not the complete denture; p-value= 0.003). Participants who had a revisit
tended to have lower quality of life but without statistical significance (p-value=0.067).
