TMJ symptoms were observed to be higher in the patients with RA, AS and pSS than the control group. Dentists and rheumatologists should be aware of TMJ symptoms in patients with rheumatic diseases.
BackgroundThe current study evaluated the effects of fixed and removable space-maintainers on halitosis and oral health of children.MethodsForty-three patients randomly selected between the ages 4–10 whom fixed or removable space maintainers were indicated in Gazi University, Faculty of Dentistry, Department of Pedodontics. The inclusing criteria were: caries-free (with/without restorations), with absence of periodontal diseases, without systematic disease, no mouth breathing and no use of antibiotics the 2-months period before the study. The patients were subdivided into two groups: the group treated with fixed space maintainers (group 1, n = 27), the group treated with removable space maintainers (group 2, n = 16). The the plaque index (PI), gingival index (GI), periodontal screening index (PSI), tongue coating index (TCI) records and the halitosis measurements were obtained at three time periods (T1: immediately after application, T2: 1 week after application, T3: 5 weeks after application). The measurement values of T1 served as control.ResultsNo statistically significant difference was found in the PI, GI, PSI, TCI and halitosis measurements between T1–T2, T2–T3 and T1–T3 in both appliance groups and between the groups (p > 0.05).ConclusionsThe fixed and removable space maintainers did not affect oral health status and halitosis significantly.
BackgroundArtefacts in images related to patient movement decrease image quality, potentially necessitating re-scanning, which leads to an extra radiation dose for the patient. Thus, avoiding patient motion reduces patient exposure to radiation. The aim of this study was to analyse image motion artefacts (MAs) and how they are affected by patient anxiety during cone beam computed tomography (CBCT) examination.MethodsA total of 100 patients undergoing CBCT examination were investigated. The State Trait Anxiety Inventory (STAI-S and STAI-T) form was used to measure patient anxiety. Patient’s age, gender, dental anxiety score, diagnostic reason for CBCT examination, field of view (FOV), acquisition time, anatomical area, and presence of motion artefacts on images were recorded. Comparisons of the parameters were evaluated using Pearson’s correlation, the chi-square test, the Mann-Whitney U test, the Kruskal-Wallis test and t-tests. The significance level was set at 0.05.ResultsThe mean values of the scores for the total population were 37.2 for the STAI-S and 41.6 for the STAI-T. Women exhibited higher anxiety levels than men. The patients’ anxiety scores were significantly correlated with dental fear. The prevalence of patients showing motion artefacts was 6%. The mean age of patients with motion artefacts on their images (56.83) was higher than that of patients without (39.14). There was no relationship between motion artefact presence and patient gender, anxiety score, diagnostic reason for CBCT examination, FOV, acquisition time, or anatomical area. Patients showing motion artefacts on their images had higher STAI scores than those with no motion artefacts (non-significant).ConclusionsThe population in this study experienced anxiety before CBCT scanning. Excessive anxiety did not clearly affect whether image motion artefacts were generated during CBCT examination, although a non-significant increase in STAI scores was noticed in patients with motion artefacts on their images.
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.
