A strong correlation was found between tongue lesions and age, sex, oral hygiene and habits in Turkish dental outpatients. An efficient oral health program such as the elimination of risk habits and attention to cultural practices may improve tongue hygiene.
Only 16.7% of dentures worn by the elderly are properly cleaned. Older dentures tended to be dirtier than newer ones. There was a significant correlation between poor denture hygiene and prevalence of Candida.
Conventional methods of caries detection, including the gold standard of histological examination, have certain disadvantages that must be addressed prior to validating any other diagnostic technique-current or new. Here we evaluated the validity of micro-computed tomography (micro-CT) as an alternative gold-standard technique for caries detection. Sixty teeth with suspected occlusal caries were chosen from a pool of teeth extracted for orthodontic, periodontal, or surgical reasons. Identical reference points were marked on photographs taken for teeth and were used to evaluate each method. Dimensions of caries were assessed by two calibrated examiners using the ICDAS-II visual examination system, bitewing radiographs, and micro-CT. The teeth included in the study were selected randomly from solution before all measurements. For micro-CT, the device was set to 50 kV, 800 µA, pixel size 15 µm (at 1024 × 1024 resolution), and 1° rotation step. NRecon software (SkyScan) was used to obtain reconstructed images. For each diagnostic method, results were compared with histology results using the McNemar test. Receiver operator characteristic (ROC) analysis was also performed for each method (Z-test; p < 0.05). Besides showing a high correlation with histology results, micro-CT yielded the greatest values at the D3 threshold; moreover, accuracy and area under the ROC curve (AUC) values were greatest at the D1threshold. Our results indicate that micro-CT performs as well as or better than histological examination for the purpose of comparing methods for caries detection.
Bilateral bifid mandibular condyles are rare and may appear as a congenital or developmental anomaly. A case of bilateral bifid mandibular condyles is reported. The patient had no history of trauma and no link was apparent with respect to the patient's medical history. In this case, the condition was an incidental panoramic radiographic finding. Magnetic resonance imaging findings revealed bilateral anterior disc displacement without reduction. The radiographic appearance of this anomaly and the literature on bilateral bifid condyles are reviewed.
The aim of this study was to investigate the relationships between dental age and bone age in Turkish adolescents with constitutional delay of growth and compare them with a group of normal, healthy adolescents. Left hand and wrist radiographs and dental panaromic radiographs of 33 adolescents (25 boys and 8 girls) aged between 10 and 16 years with constitutionally delayed growth were assessed. The control group comprised 41 healthy adolescents (24 boys, 17 girls) aged between 10 and 16 years. Bone age was determined according to Greulich and Pyle; dental age was assessed using the Demirjian method. In the control group, no statistical difference was found between chronological, bone and dental ages. In the group of adolescents with constitutional growth delay, there was no significant difference between chronological age and dental age, but the differences between dental age and bone age and between chronological age and bone age were found to be statistically significant. It was found that Demirjian's dental age assessment is a valid method for scoring dental age in Turkish adolescents. Adolescents with constitutional delay of growth had dental maturation appropriate for chronological age, but not for bone age.
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.
