IntroductionDentofacial disorders may potentially significantly affect the quality of life. Objectives of this study were to validate translated and culturally adapted Orthognatic Quality of Life Questionnaire (OQLQ) on a cohort of Serbian patients with malocclusions.MethodsThe questionnaire was validated in 111 consecutive patients with malocclusions, seen between December 2014 and February 2015 at the Clinic of Orthodontics, Faculty of Dental Medicine, University of Belgrade. Clinical validity was assessed comparing the mean scores for the four subscales of the OQLQ and mean PAR pre-treatment score. In order to assess whether the allocation of items in the subscales corresponds to their distribution in the original questionnaire, an exploratory factor analysis (principal component analysis with varimax rotation) was conducted.ResultsThe results of the internal consistency analysis demonstrated good relationships between the items; Cronbach’s alpha coefficients for the four subscales were highly significant (p<0.001) (0.88-0.91). All items were significantly correlated between baseline and the retest (6 weeks after). The correlations between the PAR and all four domains of the OQLQ were all significant (p<0.01). The loading weights obtained in the exploratory factor analysis showed that this model revealed four factors with eigenvalue greater than 1, explaining the 64.0% of the cumulative variance. The majority of the items (86.4%) in the Serbian version of the OQLQ presented the highest loading weight in the subscales assigned by the OQLQ developer.ConclusionsThe psychometric properties of the OQLQ (Serbian version) have exceptional internal consistency and reproducibility as an instrument for evaluation of dental malocclusions. Additionally, this questionnaire may be useful as a supplementary outcome measure in persons with malocclusions.
During orthodontic treatment, pain is a subjective experience influenced by several factors. Orthodontic patients consume analgesics at different rates to alleviate this pain. Correlations between orthodontic pain and analgesic consumption were analyzed. Predictive factors to analgesics consumption were not statistically analyzed. This study was conducted to identify the predictive factors for analgesic consumption after initiation of orthodontic treatment with fixed appliances. Two hundred and eighty-six patients involved in this study kept a seven-day diary in which they recorded pain intensity (using a 0–10 numerical rating scale), analgesic consumption, localization of pain, pain triggers, and pain characteristics. Univariable analyses identified potential predictive factors: age, gender, pain intensity, pain localization, pain while chewing, pain at rest, night pain, headache, pulsating pain, sharp pain, dull pain, and tingling. Logistic regression was conducted to create a model that could predict analgesic consumption. Multivariate analyses demonstrated that analgesic consumption was increased by increased age, increased intensity of pain, and presence of a headache. Overall, the model explained 33% of analgesic requirement variability. Age, intensity of pain, and headache proved to be predictors of analgesic consumption. Knowledge of such factors may help clinicians identify orthodontic patients who will consume analgesics on their own.
the RS and it lists the most important forms, such as improper medical diagnosis, rigging traffic accidents, agreed car theft, inflated invoices for repairs, later calling the police, fraud in area of property insurance and others. Next follows the statistics insurance fraud and the RS for the period 2010-2013 years, the analysis of the structure of registered persons and the relationship to corruption offenses. The final part includes measures and recommendations for the control and prevention of insurance fraud.
Background/Aim: This investigation aimed to evaluate the intensity of self-reported pain and frequency of self-medication with analgesics during the initial phase of orthodontic treatment with fixed appliances and to compare possible differences between the maxillary and mandibular teeth. Material and Methods: In this observational clinical trial 68 patients had similar orthodontic forces (the same bracket-slot and prescription, archwire size and material, and treatment plan) applied on maxillary and mandibular teeth. The patients recorded pain intensity and use of analgesics for the first seven days of treatment. Comparisons between maxillary and mandibular teeth regarding the pain intensity and self-medication frequency were performed by Wilcoxson Signed Ranks Test and McNamara Test for Matched Pairs, respectively. Results: The patients reported moderate pain in both jaws which decreased significantly with each day of treatment. Still, during the initial three days of treatment intensity of pain for maxillary teeth was significantly lower compared to the mandibular teeth. Patients reported analgesics consumption for both jaws, without a statistically significant difference between them. Conclusions: The patients have reported orthodontic pain of higher intensity in the mandibular arch compared to the maxillary arch during the initial phase of orthodontic treatment with fixed appliances.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
