Abstract
AIMS: To assess the oral health impact profile (OHIP) on edentulous subjects who needed to have their dentures replaced either by a copy technique or a conventional technique, and to determine whether any change in the subjects' assessment of their original and replacement dentures impacted on oral health related quality of life parameters. BACKGROUND: The OHIP is an instrument used to measure subjects' perceptions of the social impact of oral disorders on their well being. Changes in the OHIP may occur when subjects need to have their complete dentures replaced. Furthermore, it is possible that the method by which the dentures are constructed may impact on this. METHODS: A total of 65 edentulous subjects were studied. Thirty-three subjects had their dentures constructed by a copy technique and 32 by a conventional technique. Subjects completed the OHIP-14 questionnaires before and after being provided with a set of replacement complete dentures. They also assessed specific features of the upper and lower dentures. Responses were recorded on a Likert scale. RESULTS: For many subjects, the responses in the before treatment questionnaires were at the lower end of the Likert scale, indicating that there were no major impacts on oral health related quality of life parameters. There were no major differences between the copy denture subjects and the conventional denture subjects in relation to the change in OHIP scores before and after treatment. Generally subjects expressed improved satisfaction with the new lower denture. However, for the copy denture group there were significant improvements for all seven assessments compared with only five out of seven assessments for subjects in the conventional group. CONCLUSION: For these groups of edentulous subjects, although they may need dentures to be replaced after a period of wear, this does not necessarily have significant impacts on oral health related quality of life parameters. It seems likely that this is the main reason why the provision of new dentures by either a copying or conventional technique did not result in major changes to the OHIP.
