Treatment Outcomes and Assessment of Oral Health Related Quality of Life in Treated Hypodontia Patients.

OBJECTIVES: 1. Assess treatment outcomes and oral health related quality of lifeM (OHRQoL) of hypodontia patients after completing dental treatment at the Eastman Dental Hospital and compare it with British public norms. 2. Assess factors which have an association with patients' reported OHRQoL. METHODS: Hypodontia patients who finished their treatment completed a 16-item questionnaire (UK oral health related quality-of-life measure), a list of four questions about their satisfaction with treatment received and a clinical assessment using modified USPHS criteria. RESULTS: The sample included 52 participants; median age 28 years (range 16 - 61 years). All participants had completed treatment for at least 6 months (range 6-60 months). Clinical assessment revealed 4 of the participants had complications requiring treatment. The OHRQoL mean scores of the sample were statistically significantly higher than the mean scores of the British public norms for most age groups (P⟨0.05). Factors which revealed association with OHRQoL scores were: gender (P=.047) and satisfaction with dental aesthetics (P=.006). CONCLUSIONS: Hypodontia patients following treatment reported higher OHRQoL average scores compared to the British population. Higher OHRQoL scores were related to patients' satisfaction with dental aesthetics after treatment. Females tended to report higher OHRQoL scores than males.

The survival and clinical performance of anterior composite resin restorations and posterior indirect and cast restorations used to treat generalised tooth wear.

Objective To evaluate the survival and clinical performance of restorative materials used in the rehabilitation of generalised severe tooth wear within a UK NHS postgraduate teaching hospital.Methods The clinical performance of 527 restorations on 20 patients with generalised severe tooth wear was reviewed after a mean period of five years. Anterior teeth were restored with direct composite resin and posterior teeth with indirect restorations. The study used the modified United States Public Health Service criteria for restoration assessment. Survival of the restorations was analysed using Kaplan-Meier survival curves, the log-rank test and the Cox proportional hazards regression analysis.Results The sample included 20 participants: 13 men and 7 women, with a median age of 51.8 years (range: 33-73 years). The median survival time for all restorations was 11.3 years when major failures were considered and 5.9 years for restorations when all types of failure were considered. A median survival time of 5.9 years for composite resin restorations and over seven years for cast restorations was found when considering all failures. Composite resin restorations commonly failed as a result of fracture, wear and marginal discolouration. Factors significantly influencing restoration survival were the material used, aetiology, incisal relationship and tooth location. The biological complications associated with this treatment regime were rare. Patient satisfaction remained generally high, with greatest dissatisfaction related to treatment time.Conclusions The use of anterior composite resin with posterior indirect restorations to treat generalised severe tooth wear is a viable treatment modality with very few major complications.
