Validity and reliability of the Oral Impacts on Daily Performance (OIDP) scale in the elderly population of Bosnia and Herzegovina Objectives: To adapt the Oral Impacts on Daily Performance (OIDP) index for elderly people in Bosnia and Herzegovina and test its validity, reliability and responsiveness to change. Background: Clinical measures alone may not be adequate for assessing the oral health of individuals. Subjective oral health indicators tested within a particular cultural context may not be relevant across cultures. Materials and methods: The study population comprised 231 free-living adults aged 65 years or older. The OIDP was cross-culturally adapted from English into the Serbian language and its psychometric properties were tested. Data were collected using a clinical examination and a questionnaire containing the OIDP. Results: In terms of reliability, Cronbach's alpha coefficient was 0.82 and the intraclass correlation coefficient 0.88. The very high correlation of OIDP with self-rated oral health (r = 0.78) verified criterion validity, while construct validity was demonstrated through its significant and graded associations with other subjective health measures. OIDP change scores on a treated subsample showed moderate effect size (0.59) and were associated with perceptions of oral health change, providing evidence for its responsiveness to change. Conclusion: The Bosnian version of the OIDP showed satisfactory validity, reliability and responsiveness to change confirming its appropriateness for use among older populations in Bosnia and Herzegovina.

This study aimed to assess the prevalence and the severity of oral impacts and the relationships between oral health-related quality of life (OHRQoL) and clinical measures of oral function in a sample of older adults in Bosnia. The sample comprised 261 community-dwelling adults of ≥65 yr of age. Participants were randomly drawn from three senior day-centres for elderly people. Data were collected using clinical examination and a questionnaire. The OHRQoL was assessed through the Oral Impacts on Daily Performances (OIDP) measure, in terms of the prevalence, intensity, and extent of oral impacts. Overall, 55.2% reported at least one oral impact in the last 6 months. Difficulty eating (43.3%) and difficulty speaking (34.1%) were the most common impacts. These were also the most severely affected performances, while 'going out' and 'enjoying the contact of other people' were the least severe. A higher number of natural teeth, natural occluding pairs, and anterior and posterior occluding pairs were all significantly associated with a lower prevalence of oral impacts and correlated with the OIDP score, even after adjusting for sociodemographic factors. The prevalence of oral impacts was high and there was a strong and consistent association between OHRQoL and clinical dental indicators of function.

Introduction. The aim of this study was to translate the Child Oral Impact on Daily Performance index into Serbian language and to evaluate its reliability in practice. Material and Methods. Following internationally established methods, adaptation of the Child Oral Impact on Daily Performance index for children and adolescents in the Serbian speaking areas consisted of three steps: forward translation of the Child Oral Impact on Daily Performance index, backward translation, and a pilot study. Results. A pilot study included 42 participants (21 males and 21 females), mean age of 12.0 ± 1.01 years. All items showed a corrected item-total correlation coefficient above >0.20 and the standardized Cronbach's alpha coefficient was 0.80. All correlation coefficient values were positive. The prevalence of oral health impact measured by the Child Oral Impact on Daily Performance index was relatively high and 54.8% of the participants reported at least one oral impact on the daily performance in the last 3 months. The most common activities affected were eating (38.1%) and cleaning the teeth (16.7%). Conclusion. The Serbian version of the Child Oral Impact on Daily Performance index is suitable for use in everyday practice and it provides useful information in the evaluation of oral health-related quality of life. The prevalence of oral impacts was high with the most prevalent impact referring to eating. Further clinical research, including larger number of participants, is required for exact verification of the Child Oral Impact on Daily Performance index.

Introduction/Objective This study was aimed at evaluating dentin permeability after irrigation with sodium hypochlorite (NaOCl) and final rinse with chlorhexidine (CHX), ethylenediamine tetraacetic acid (EDTA) + CHX, and new combination products: QMiX or MTAD. Methods Roots of 60 maxillary incisors were randomly divided into five groups (n = 12) before instrumentation and irrigation with NaOCl according to the final irrigation regimen: CHX (2% CHX), EDTA + CHX (17% EDTA + 2% CHX), QMiX, MTAD, and control group (distilled water). After final irrigation, ten roots of each group were horizontally sectioned and dye penetration was evaluated in the coronal, middle, and apical thirds. Remaining samples were subjected to scanning electron microscopy. Data were analyzed with ANOVA/Tukey's test. Results Less dye penetration was found in CHX group compared with control as well as with QMiX and MTAD group in all thirds (p < 0.05). A significant difference between the control and EDTA + CHX, QMiX or MTAD group was observed only in the apical root third (p < 0.05). Conclusion Dentin permeability was significantly reduced after final irrigation with CHX, but not after use of other final irrigation solutions, except in the apical third of the root canal.

Background/Aim. Oral health is an important part of overall health. Good oral health is important for oral diseases prevention and health maintenance of respiratory system. The aim of the study was to evaluate oral hygiene and periodontal health parameters of asthmatic children and to compare them with children without asthma as well as to evaluate those parameters according to type of used medications and time of taking medications in children with asthma. Methods. This epidemiological study included 68 children with asthma and 68 children without asthma or any other chronic disease aged from 6 to 16 years. Parameters used in this study were Greene-Vermillion index, Löe-Silness gingival index and Community Periodontal Index (CPI). Results. Good oral hygiene (31.1%) was more present in children without asthma whereas poor hygiene (20.0%) was more frequent in children with asthma (p < 0.001). Healthy gingiva was more frequent in children without asthma (25%) while mild (58.8%) and moderate gingival inflammation (5.9%) were more frequent in the group of children with asthma (p < 0.01). Mean CPI values were higher in children with asthma (p < 0.001). Mean values of Plaque Index, Gingival Index and CPI did not show statistically significant difference in relation to type of administered medication. However, taking medications in the afternoon was related to higher mean values of Plaque Index and Gingival Index (p < 0.05) within the group of children with asthma. Conclusion. Children with asthma had poorer oral hygiene and were diagnosed with greater values of oral hygiene and periodontal indices compared with the group of children without asthma. For this reason, it is necessary to promote oral health and establish good oral hygiene habits in asthmatic children.

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 to change of the child Oral Impacts on Daily Performances (C-OIDP) index in a Bosnian 12-14 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 to change 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 to change and can be used as an appropriate OHRQoL measure for further epidemiological researches.

Introduction. ALBO-HA (Vinca, Serbia) is new nanostructured calcium aluminate cement, synthesized as a potential alternative to mineral trioxide aggregate (MTA). The purpose of this study was to compare the periapical tissue response to new nanostructured calcium aluminate cement ALBO-HA with white MTA (MTA Angelus, Londrina, Brasil) as root-filling material into the root canal of sheep?s teeth. Material and methods. Sixteen mandibular incisors from two 24-month-old sheep were used. Root canals were prepared and filled with ALBO-HA (group 1) or MTA (group 2) (eight teeth per group in each sheep). After four weeks the animals were sacrificed, teeth with surrounding tissue removed, and histologically processed. The sections were analyzed for determination of scores of the following parameters: periapical inflammatory infiltrate, newly mineralized apically formed tissue, apical periodontal ligament space thickness and resorption of dentin, cementum and bone. Data were analyzed statistically (?=0.05) using Mann-Whitney U test. Results. Slight inflammatory infiltrate was observed in 75.0% and 62.5% of samples in the group 1 and group 2, respectively (p>0.05). Partial newly mineralized apically formed tissue was found in 75.0% of samples in the group 1, and 87.5% of samples in group 2 (p>0.05). No significant difference was noted for periodontal ligament space thickness (p>0.05). Resorption of dentin, cementum or bone was not observed. Conclusion. ALBO-HA and white MTA Angelus had a similar effect on inflammation, newly mineralized apical tissue formation and thickness of periodontal ligament space after root canal filling under the present experimental conditions.

Introduction. Dental caries is still an important social health problem in many countries. The aim of this study was to determine the incidence and impact of oral discomfort, particularly caused by dental caries on the quality of life of middle-aged people as well as the association between oral problems caused by caries and the current status of teeth. Material and Methods. The study included 72 patients, age 25-45 years. Serbian version of the questionnaire Oral Impacts on Daily Performance (OIDP) was used to determine the overall impact of oral health as well as the specific effect of caries (SP-OIDP) on the quality of life. To determine the status of teeth the DMFT index was used. Results. The incidence of oral health impact on daily activities was 68.1%. Carious teeth affected food intake (40.0%) and brushing teeth (31.0%) but had no effect on showing teeth and maintaining normal emotional state. Caries was the cause of oral discomfort in more than half of the respondents. Of all clinical variables only DMFT>22 was associated with the SP-OIDP score after inclusion of socio-demographic factors in the analysis (rs=0.273). Conclusion. The results of this study indicate that the incidence of the effect of oral conditions on the quality of life is high with most respondents showing difficulties while eating. Using specific questionnaire it was noted that dental caries had a significant effect on oral functions of respondents. Also, there was a significant correlation between dental status and the quality of life of middle-aged people.
