Psychometric properties of the Child Oral Impacts on Daily Performances (C-OIDP) index: a cross-sectional and an intervention study of adolescents in Bosnia and Herzegovina.

BACKGROUND: The clinical measures are not sufficient to assess oral health because they don't tell us anything about functional and psychosocial aspects of oral health and do not reflect person's concerns and subjectively perceived symptoms. This study aimed to investigate the validity, reliability and responsiveness of the child Oral Impacts on Daily Performances (C-OIDP) index among Bosnian 12-14 years old schoolchildren. METHODS: The study population comprised 203 primary schoolchildren aged 12-14 years attending three schools in the eastern part of Bosnia and Herzegovina. Data were collected through: a clinical oral examination, oral health questionnaire and C-OIDP questionnaire. The validity and reliability of the C-OIDP were tested on a sample of 203 school-going children while responsiveness of the C-OIDP was assessed on 42 randomly chosen participants requiring a dental treatment. RESULTS: In terms of reliability, Cronbach's alpha coefficient and the intraclass correlation coefficient were 0.86 and 0.85, respectively. Regarding the testing of construct validity, the C-OIDP score was increased as children's self-reported oral health changed from excellent to very bad and from very satisfied to dissatisfied. There was a significant improvement in C-OIDP post-treatment score compared with C-OIDP pre-treatment score. Overall, 63.4% of participants reported at least one oral impact in the last 3 months. The most affected performances were "eating" (38.4%) and "speaking" (25.1%). CONCLUSION: The Bosnian version of the C-OIDP showed satisfactory validity, reliability and responsiveness and can be used as an appropriate OHRQoL measure for further epidemiological researches.

The effect of final irrigation with MTAD, QMix, and EDTA on smear layer removal and mineral content of root canal dentin.

To compare the smear layer removal ability and mineral content of root canal dentine after initial irrigation with NaOCl and final irrigation with MTAD, QMix, and 17% EDTA. Forty extracted human maxillary incisors before root canal preparation and irrigation with NaOCl were randomly divided into four groups (n = 10) according to the type of final irrigants used: MTAD, QMix, 17% EDTA, and control (sterile distilled water). Scanning electron microscopy (SEM) was used to assess the presence of smear layer. SEM energy-dispersive X-ray spectroscopy was used to quantify dentin mineral composition in MTAD, QMix, 17% EDTA group, and in no-treatment samples (no-treatment group; n = 10). Among the various chelating agents, there were no significant differences in the smear layer removal in the middle and coronal thirds (p > .05). In the apical third, QMix removed significantly more smear layer than 17% EDTA (p < .05), but similarly to MTAD (p > .05). Final irrigation with MTAD resulted in a significant increase in the carbon (C) value compared to EDTA (p < .001). There was no significant difference in the mineral composition between the MTAD and the QMix group, although the values of the mineral elements were significantly altered in the MTAD group. QMix had smear layer removal capability similar to MTAD but better than EDTA in the apical third. MTAD yielded the most pronounced effect on mineral component of root dentin; however, differences were significant only for C level compared to 17% EDTA.

Changes in Oral Health Related Quality of Life (OHRQoL) and Satisfaction with Conventional Complete Dentures Among Elderly People.

PURPOSE: To assess the changes in oral health-related quality of life (OHRQoL) and satisfaction among older adults after receiving new complete dentures, and the association of age, gender, education, medical history, past prosthetic history (number of previous complete dentures and time since current complete dentures) and quality of existing complete dentures with patients' ratings of satisfaction with their complete dentures. MATERIALS AND METHODS: The study comprised 114 community-dwelling adults ≥ 65 year of age, all wearing complete dentures in both jaws. The sample was selected from four senior day centres. Data were collected using clinical oral examinations and a self-administered questionnaire. Dentures were clinically evaluated for retention, stability, occlusion, articulation and vertical dimension. The questionnaire recorded data on sociodemographic information, previous denture history, oral satisfaction scale (OSS), and OHRQoL through the Oral Impacts on Daily Performance (OIDP) scale. RESULTS: There was a significant improvement in OHRQoL after treatment (mean OIDP score: 2.7) compared to before treatment (mean OIDP score: 6.6). The largest changes were in relation to impacts on eating (33.3% to 15.9%) and smiling (17.5% to 4.5%). Six months after placement of the dentures, patient satisfaction improved compared to before treatment (p < 0.001). The results of this study demonstrated that satisfaction was correlated with age, gender, and past prosthetic history in the patients rehabilitated with complete dentures. CONCLUSIONS: The provision of new dentures among older adults resulted in significantly better satisfaction and OHRQoL than wearing existing dentures. There was no significant correlation between the clinical assessment of the dentures and patients' satisfaction with them.
