Effectiveness of a combination denture-cleaning method versus a mechanical method: comparison of denture cleanliness,patient satisfaction,and oral health-related quality of life

Purpose

Effective denture plaque control is necessary in elderly individuals to prevent oral and systemic diseases. However, comparative studies of denture cleaning methods are limited, especially those investigating patient satisfaction. The present study aimed to evaluate effectiveness of a mechanical denture cleaning method versus a combination of mechanical and chemical methods in terms of denture cleanliness, patient satisfaction, and oral health-related quality of life (OHRQoL).

Validity and reliability of the Swedish versions of the short-form Child Perceptions Questionnaire 11–14 and Parental Perceptions Questionnaire

Objective: To examine the validity and reliability of the Swedish versions of the short-form Child Perceptions Questionnaire 11–14 (CPQ_11–14) and Parental Perceptions Questionnaire (P-CPQ) for measuring children’s oral health-related quality of life (OHRQoL).

Material and methods: The sample comprised 247 children and parents. OHRQoL was assessed by asking each child and their accompanying parent to complete the relevant questionnaire. To allow test–retest analysis, 30 children and 32 parents were asked to complete the instrument a second time within 2–4 weeks.

Results: In terms of construct validity, significant correlations were observed between CPQ scale scores and the global ratings of oral health and overall well-being for both the CPQ_11–14 and the P-CPQ. Regarding internal consistency, Cronbach’s alphas for the total scales were 0.81 and 0.77, respectively, indicating good reliability, and internal consistency for the subscales (two or four dimensions) was acceptable. Test–retest reliability was good for the CPQ_11–14 total scale (ICC 0.77) and acceptable for the P-CPQ total scale (ICC 0.63).

Conclusions: The Swedish versions of the short-form CPQ_11–14 and P-CPQ are both valid and reliable, and can be recommended for use among Swedish children aged 11–14 years for evaluation of OHRQoL.     

Factors associated with oral health-related quality of life in institutionalized elderly

Objective. The aim of this study was to investigate factors associated with the oral health-related quality of life (OHRQoL) of institutionalized elderly in Germany. Material and Methods. One-hundred-and-fifty-eight subjects from old people's homes were selected (mean 82.8 years). OHRQoL was measured using the Oral Health Impact Profile (OHIP). Denture characteristics (kind and age of denture, retention of removable denture, number of teeth in static occlusion) and general issues (age, gender, education level, and general pain status) were assessed. All factors were subjected to bivariate testing for their effects on the OHIP summary score (OHIP-SC) and to multivariate testing in subjects with removable dentures (n=128); a linear regression model with backward elimination was used, with OHIP-SC as the dependent variable. Results. In the context of other studies, a median OHIP-SC of 29 indicated highly impaired OHRQoL. According to the bivariate analysis, retention, age of denture, number of teeth in static occlusion, general pain status, and education all exhibited significant influence on OHIP-SC. In the final linear regression model, general pain status, education level, and retention of denture remained at a statistically significant level. The model explained 34% (R²=0.34) of the variance of the OHIP-SC. The kind of denture had no significant impact on OHIP-SC. Conclusions. In contrast to other groups, the kind of denture exhibited little impact on OHIP-SC for this highly specific collective. However, there were functional aspects of dentures which seemed to be important. Non-dental factors had a striking effect on OHRQoL.     

The combined use of corticotomy and clear aligners: A case report

Objective:To describe an orthodontic treatment that combines an esthetic approach (clear aligners) with surgery (alveolar corticotomy).Materials and Methods:A patient with moderate dental crowding and Class I skeletal and molar relationships was selected. Orthodontic records of the patient were taken. Periodontal indexes, oral health–related quality of life (OHRQoL), and treatment time were evaluated. After we reflected a full-thickness flap beyond the teeth apices, the cortical bone was exposed on the buccal aspect and a modified corticotomy procedure was performed. Interproximal corticotomy cuts were extended through the entire thickness of the cortical layer, just barely penetrating into medullary bone. Orthodontic force was applied on the teeth immediately after surgery.Results:Total treatment time was 2 months. Periodontal indexes were improved after correction of crowding. A deterioration of OHRQoL was limited to 3 days following surgery.Conclusion:This case report may encourage the use, limited to selected cases, of corticotomy associated with clear aligners to treat moderate crowding.     

Professional and patient-based evaluation of oral rehabilitation in patients with tooth agenesis

Objectives: The outcome of oral rehabilitation is usually monitored with clinical tests rather than by patient's perception of change. The aim of this study was to describe the objective measure and subjective perception of oral rehabilitation in patients with tooth agenesis. Material and methods: The study included 129 patients with tooth agenesis rehabilitated with implant‐ or tooth‐supported reconstructions, and a control group of 58 patients. Professional assessments included biological, technical and aesthetic variables. An aesthetic index score included mucosal discoloration, crown morphology, crown color match, occlusal harmony, and papilla level. The Oral Health Impact Profile (OHIP) questionnaire was used to evaluate the patient‐based outcomes. Six OHIP questions were subtracted to evaluate the patient‐based aesthetic outcomes. Results: Severe root resorption was observed in 36% of the patients in whom orthodontic treatment had been performed. Twelve percent of patients had implants with 5–7 mm peri‐implant bone defects. Mucosal discoloration was recorded in 57% of the patients. Twelve percent of the patients had metal visible on the buccal side. The median scores for all five aesthetic variables were acceptable in 92% of the implant reconstructions and for 83% of the tooth‐supported fixed dental prostheses (FDPs). The total OHIP score was inferior in rehabilitated patients with tooth agenesis to that of the control group without tooth agenesis. The total OHIP score after rehabilitation was <50 for 95% of the patients with tooth agenesis. The six OHIP questions concerning aesthetics demonstrated patient‐based aesthetic problems in 41% of patients treated with implant‐supported reconstructions and 47% of patients treated with tooth‐supported FDPs. Ninety‐eight percent of the group treated with implant‐supported reconstructions and 84% of the patients in the tooth‐supported FDP group were very satisfied or satisfied with the treatment outcome. Conclusions: Patients with tooth agenesis had a high risk of severe root resorption after orthodontic treatment. A better aesthetic outcome was obtained with implant‐supported reconstructions than with tooth‐supported reconstructions. A positive but not significant correlation was observed between the professional and patient‐based evaluations of aesthetic outcomes.

Oral health-related quality of life in socially endangered persons in Copenhagen,Denmark

Objective: The aims of this study were to investigate and describe the Oral Health Related Quality of Life (OHRQoL) in a socially endangered group of people and to compare the OHRQoL to other patient groups.

Material and methods: About 294 socially endangered persons attending a volunteer clinic in Copenhagen Denmark filled in the OHIP-14 questionnaire. The group was compared in mean score and reported problems to a group of patients with tooth loss and about to have a removable dental prosthesis (RDP), a group with tooth loss about to have a fixed dental prosthesis (FDP) and a control group without tooth loss.

Results: Significantly higher OHIP-14 score was seen in the socially endangered group (15.5 (SD 12.6)) compared with the control (1.9 (SD 2.7)) and the FDP group (9.4 (SD 8.2)) but not the RDP group (13.1 (SD 10.5)). This difference was not changed after stratifying in age groups. Problems related to psychological disability, social disability, and handicap were more frequent in the social endangered group than for the other groups. The items pain, tense, diet, relax, life, and function stand out as problems in the socially endangered group compared to the other groups.

Conclusion: The OHRQoL is highly impaired in the socially endangered persons and at least to the level of persons with great tooth loss about to have an RDP. The problems seem to be more handicapping in the socially endangered compared with other patient groups known to have high impairment.
