Effect of malocclusion on adults seeking orthodontic treatment.

INTRODUCTION: Our objective was to examine the Teen Oral Health-related Quality of Life (TOQOL) questionnaire for use in adults receiving orthodontic treatment and assess validity and reliability by age group. METHODS: Teenagers from 10 to 18 years and adults 18 and over completed surveys at the orthodontic clinic at Boston University. The survey consisted of sociodemographic information, dental behavior questions, and the TOQOL instrument. Malocclusion severity was assessed using the Index of Orthodontic Treatment Need. RESULTS: Overall, 161 teens and 146 adults participated. The mean ages were 13 years for the teens and 32 years for the adults. Subjects were represented by both sexes and diverse racial and ethnic backgrounds. In general, scores overall and by domains were higher for adults than for teens, signifying a greater effect of the malocclusion on the quality of life. Mean TOQOL scores as well as emotional and social domain scores (P <0.001) were worse (17.6) in adults than in teens (11.9; P <0.01). Construct validity was supported by strong a association of TOQOL scores with self-reported oral health. The Cronbach alpha was higher in adults overall and for all domains (0.75 in adults compared with 0.68 in teens). CONCLUSIONS: Adults who come for orthodontic treatment appear to be more affected by their malocclusion than are teens. The total TOQOL score and the emotional and social domains were significantly higher for adults. The total TOQOL score and the emotional and social domains were significantly higher (worse) for adults than teens. This project suggested that TOQOL may be a useful way to measure the impact of malocclusion on the quality of life in both adults and teens.

Development of the Teen Oral Health-Related Quality of Life Instrument.

OBJECTIVE: The aim of this study was to develop the Teen Oral Health-Related Quality of Life instrument (TOQOL) and demonstrate its validity and reliability in a diverse sample of 13-18-year-old adolescents. METHODS: A total of 363 adolescents aged 13-18 years participated in this cross sectional study. Oral screening examinations were conducted to collect oral health status data. Adolescents completed the TOQOL and a generic measure of health-related quality of life, the PedsQL. The psychometric properties of the TOQOL were evaluated in terms of face, content, convergent, concurrent and discriminant validity in addition to internal reliability. RESULTS: The 16-item TOQOL covers five domains: Physical functioning, Role functioning, Social functioning, Oral problems, and Emotional functioning. The total scale and subscales showed satisfactory reliability with Cronbach alpha ranging from 0.75 to 0.92. TOQOL scores showed significant associations with perceived oral health status and the PedsQL (convergent validity) and discriminated well between adolescents with caries and adolescents who were caries free (discriminate validity). CONCLUSION: The TOQOL is a valid and reliable oral health-related quality of life measurement that can be recommended for self-report in adolescents aged 13-18 years.

The Dietary Approaches to Stop Hypertension Diet and New and Recurrent Root Caries Events in Men.

OBJECTIVES: To examine the effect of overall dietary quality on number of teeth with new or recurrent root caries events during follow-up (root caries increment). DESIGN: Prospective study with dental examinations approximately every 3 years over 20 years. SETTING: Veterans Affairs Dental Longitudinal Study in greater Boston, Massachusetts, area. PARTICIPANTS: Men aged 47 to 90 (N = 533). MEASUREMENTS: A single calibrated examiner assessed root caries and restorations, calculus, probing pocket depth, and attachment loss on each tooth at each examination. The adjusted root caries increment (root-ADJCI) was computed from new and recurrent root caries events on teeth with recession of 2 mm or more. Dietary information was obtained from food frequency questionnaires. An adherence score was computed by comparing consumption frequency of 10 food groups (fruits, vegetables, total dairy, low-fat dairy, meat, total grains, high-fiber grains, legumes, fats, sweets) from the Dietary Approaches to Stop Hypertension (DASH) diet guidelines. Mean root-ADJCIs were compared according to DASH adherence score quartile using generalized linear negative binomial regression models, controlling for age, number of teeth at risk of root caries, time at risk of root caries, calculus, presence of removable denture, history of dental prophylaxis, body mass index, and smoking status. RESULTS: Men with DASH adherence scores in the highest quartile had a 30% lower mean root-ADJCI (1.86 teeth) than those in the lowest quartile (2.68 teeth) (P = .03). Root-ADJCI was lower with greater adherence to recommendations for vegetables and total grains and greater with greater sugar-sweetened carbonated beverage consumption. Root caries incidence rate did not vary significantly between quartiles. CONCLUSION: A higher-quality diet may reduce root caries risk in older men.

Development and validation of a measure of pediatric oral health-related quality of life: the POQL.

OBJECTIVE: To develop a brief measure of oral health-related quality of life (OHQL) in children and demonstrate its reliability and validity in a diverse population. METHODS: We administered the initial 20-item Pediatric Oral Health-Related Quality of Life (POQL) to children (Child Self-Report) and parents (Parent Report on Child) from diverse populations in both school-based and clinic-based settings. Clinical oral health status was measured on a subset of children. We used factor analysis to determine the underlying scales and then reduced the measure to 10 items based on several considerations. Multitrait analysis on the resulting 10-item POQL was used to reaffirm the discrimination of scales and assess the measure's internal consistency and interscale correlations. We established discriminant and convergent validity with clinical status, perceived oral health and responses on the PedsQL, and determined sensitivity to change with children undergoing ECC surgical repair. RESULTS: Factor analysis returned a four-scale solution for the initial items--Physical Functioning, Role Functioning, Social Functioning, and Emotional Functioning. The reduced items represented the same four scales--two each on Physical and Role and three each on Social and Emotional. Good reliability and validity were shown for the POQL as a whole and for each of the scales. CONCLUSIONS: The POQL is a valid and reliable measure of OHQL for use in preschool and school-aged children, with high utility for both clinical assessments and large-scale population studies.

Use of patient self-report oral health outcome measures in assessment of dental treatment outcomes.

OBJECTIVE: To assess the sensitivity of a newly developed brief measure of oral health-related quality of life (OQOL). METHODS: Self-assessed oral health and OQOL were measured in three groups of patients who had presented for either prophylaxis (n = 32), endodontic care (n = 15), or for a denture (n = 16) in a dental school setting before and after treatment. Main outcome measures included the single-item self-report of oral health (OH-1) and the 6- and 12-item versions of a new OQOL instrument. General linear modeling was used to compute means of self-reported oral health by treatment group. RESULTS: Of the 63 patients who completed the baseline questionnaire, 44 (70 percent) returned questionnaires after treatment. The sample averaged 43 +/- 15 years, 48 percent male and 55 percent with some college education. Ethnic representation included 35 percent White, 33 percent Black, and 32 percent other - mostly Latino. The mean self-reported number of teeth was 20.6. In terms of sensitivity, significant differences were observed between the treatment groups on the items assessing being upset (P < 0.05), feeling depressed (P < 0.05), and uncomfortable about the appearance of teeth or dentures (P < 0.05). However, magnitude of change, as measured by an effect size, was characterized as minimal to small in the recall and endodontic groups and borderline moderate in the denture group. CONCLUSION: The measure was sensitive to differences within groups, with a small to borderline magnitude of change.

Dental treatment improves self-rated oral health in homeless veterans--a brief communication.

OBJECTIVE: The aim of this study was to assess homeless veterans' perception of their oral health and the impact that oral disease and treatment have on self-assessed quality of life. METHODS: Outcomes included measures of general and oral-specific quality of life and functional status. Single-item self-report of oral health and the General Oral Health Assessment Index were assessed at baseline and after treatment. RESULTS: One hundred and twelve veterans completed the baseline questionnaire, and 48 completed the follow-up. Veterans who were eligible for ongoing dental care had improved General Oral Health Assessment scores, while patients who received only emergency dental care saw a decreased score (2.46 versus -2.12). General Oral Health Assessment improvement was significantly related to fewer teeth at baseline (18 versus 23), a lower baseline General Oral Health Assessment (23.6 versus 28.1), having a denture visit (22 versus 35 percent), and improvement in self-reported oral health (25 versus 42 percent). CONCLUSION: There was significant improvement in homeless veterans'perceived oral health after receiving dental care.

Adverse events associated with chlorhexidine use: results from the Department of Veterans Affairs Dental Diabetes Study.

BACKGROUND: The authors report adverse events (AEs) related to the use of chlorhexidine gluconate mouthrinse in a clinical trial of the efficacy of periodontal treatment in older adults with diabetes. METHODS: Participants were U.S. veterans with uncontrolled diabetes (hemoglobin A(1c) value > or =8.5 percent) and periodontal disease. Treatment included periodontal scaling, 0.12 percent chlorhexidine lavage during ultrasonic scaling and use of chlorhexidine mouthrinse at home. RESULTS: Forty-four (31 percent) of 140 subjects reported having AEs. Most common were taste changes and tooth staining, sore mouth and/or throat, tongue irritation and wheezing/shortness of breath; the latter was reported more commonly before chlorhexidine use than after. Only body mass index greater than 30 was significantly related to AEs. CONCLUSIONS: AEs are common among subjects using chlorhexidine mouthrinse. Most AEs (taste change and staining) were resolved easily by subjects' discontinuing mouthrinse use and receiving dental prophylaxis. No serious AEs were reported. CLINICAL IMPLICATIONS: Clinicians should advise patients using chlorhexidine mouthrinse of possible side effects. If necessary, patients should discontinue mouthrinse use and obtain medical care. Careful monitoring of AEs in patients using chlorhexidine is warranted.

Does periodontal care improve glycemic control? The Department of Veterans Affairs Dental Diabetes Study.

OBJECTIVES: Report results of a randomized-clinical trial of the efficacy of periodontal care in the improvement of glycemic control in 165 veterans with poorly controlled diabetes over 4 months. METHODS: Outcomes were change in Haemoglobin A1c (HbA1c) in the Early Treatment versus untreated (Usual Care) groups and percent of participants with decreases in HbA1c. Analyses included simple/multiple variable linear/logistic regressions, adjusted for baseline HbA1c, age, and duration of diabetes. RESULTS: Unadjusted analyses showed no differences between groups. After adjustment for baseline HbA1c, age, and diabetes duration, the mean absolute HbA1c change in the Early Treatment group was -0.65% versus -0.51% in the Usual Care group (p=0.47). Adjusted odds for improvement by 0.5% in the Early Treatment group was 1.67 (95% confidence interval: 0.84, 3.34, p=0.14). Usual Care subjects were twice as likely to increase insulin from baseline to 4 months (20% versus 11%, p=0.12) and less likely to decrease insulin (1% versus 6%, p=0.21) than Early Treatment subjects. Among insulin users at baseline, more increased insulin in the Usual Care group (40% versus 21%, p=0.06). CONCLUSIONS: No significant benefit was found for periodontal therapy after 4 months in this study; trends in some results were in favour of periodontal treatment.
