Studies show that receiving new dentures is a stressful life event and it may require considerable coping skills from individuals to get adapt to them (Klock and Haugejorden, 2002). Oral health related quality of life (OHQoL) measures are being increasingly used to evaluate oral health care and evaluate treatment outcomes (Baker et.al 2008). Cross- sectional observation on people receiving dentures suggested an element of relationship between an individual’s coping strategies and OHQoL (Heydecke et al. 2004). Further exploring this relationship and identifying the determinants of successful denture outcomes may help may help individuals receiving new dentures adapt to them better.
The main aim of my study was to explore and observe if coping strategies of individuals receiving new dentures (for the first time and as a replacement) determined its successful outcome to improve their OHQoL. Based on a systematic literature review, I also identified various clinical and psychosocial factors which may influence denture outcomes and populated them within Wilson and Cleary (1995) model which theoretically linked clinical status, individual factors and environmental and observed them alongside the coping strategies (see figure).
I carried out a prospective longitudinal cohort study on adults receiving new conventional (partial and full) dentures in a University based dental hospital in India to test the relationships that were hypothesised. This is the first study to explore the relationship between individuals’ coping strategies and OHQoL. It is particularly interesting for as to using a robust theoretical model (Wilson and Cleary, 1995) to gain more clarity on factors that influenced successful denture outcomes.
