Periodontal surgery improves oral health-related quality of life in chronic periodontitis patients in Asian population.

The effect of periodontal surgery on patients' quality of life was investigated. Sixty patients received regenerative surgery or resective osseous surgery. Oral health-related quality of life and health-related quality of life instruments were used to assess the participants' quality of life before surgery and 4 weeks after surgery. Periodontal surgery can improve patients' quality of life by alleviating the physical pain and psychological discomfort. The scores were lower (more favorable) in the regenerative surgery group, and the functional limitations of the regenerative surgery group improved substantially compared with those of the resective osseous surgery group (P = 0.0421). The patients' oral health-related quality of life scores improved significantly after periodontal surgery. Clinicians can take advantage of the positive functional oral health-related quality of life impacts of regenerative surgery.

Patient-related evaluation after systematic periodontal therapy - a clinical study on periodontal health-related quality of life (PHQoL).

PURPOSE: To evaluate how periodontitis patients perceive the outcome after long-term supportive therapy. MATERIALS AND METHODS: 281 patients (150 women/131 men) with a mean age of 55 years (range: 45-86 years) were randomly selected and consecutively interviewed using a questionnaire designed for laypersons. All patients had shown high compliance with the recommended supportive periodontal therapy (SPT) for up to 16 years (mean observation period: 12.5 years). Statistical evaluation was performed using the 2-sided t-test. RESULTS: A very high degree of confidence in the periodontal treatment (mean: 9.24, range 0-10) was found. Women noticed a higher positive impact on their social environment (P < 0.05). Patients who underwent SPT < 3 years showed a higher positive perception of treatment success than patients with SPT > 3 years (P < 0.01) and reported a greater impact on appearance (P < 0.01). Regenerative treatment demonstrated advantages over resective open flap debridement (OFD) procedures (P < 0.05) and scaling and root planing (SRP) (P < 0.05). However, treatment costs (P < 0.001) and time required (P < 0.01) for regenerative procedures were perceived as a burden. Periodontal treatment by a specialised team led to a significant reduction in the patients' complaints (P < 0.01). The SPT interval did not influence patients' perception of treatment success. CONCLUSIONS: Systematic periodontal therapy with subsequent SPT met the patients' demand to preserve oral health. Regenerative procedures prompt the perception in patients of better remission of periodontitis symptoms. Further trials should investigate clinical results of periodontal therapy regarding patient expectations.

Utilities of dentin regeneration among insured and uninsured adults.

OBJECTIVES: This population-based study measured utilities (preferences measured under conditions of uncertainty) of dentin regeneration (DR), a potential new therapy, root canal therapy (RCT), and extraction (EXT). METHODS: A representative sample of dentate adults (aged 18-69 years) was randomly selected from the Detroit area. A computer program was used to administer the standard gamble (SG) method and record utility score (US) for treatment options of a tooth with reversible pulpitis using the SG method. For the SG method, two anchor states were used: filled tooth with full oral health and filled tooth with severe and continuous pain leading to EXT. Additional data were obtained using a self-administered questionnaire. RESULTS: Out of the 807 adults who resided in 446 screened and selected households, a final sample of 630 adults who resided in 368 households were interviewed. The mean US for DR with 75 and 95% success rates were 72.5 and 86.2 (on a 0-100 scale), respectively. The US for RCT and immediate EXT were 75.6 and 31.3, respectively. Eleven per cent of the adults valued DR with 95% success probability higher than a simple filling with full oral health for life. There were no statistically significant differences in the average US of DR between insured and uninsured adults. Factors such as gender, race, education, income and insurance status, experiences with EXTs or root canal treatment, regularity of dental visits, quality of life, and quality of oral health were not significantly associated with the scores of DR. There was, however, a small but significant interaction between race and dental insurance, and race and gender. CONCLUSION: This population-based study found that DR was highly preferred to other standard treatment options.
