Of the Class III cases, the general dentists chose orthognathic surgery for both surgery and facemask cases (93.1%, 66.4% respectively). For the severe open bite case, orthognathic surgery was chosen with a ratio of 81.2%, and orthognathic surgery was decided as not necessary for the mild open bite case (74.8%). Among the surgery cases, mandibular retrusion for the Class II case (94.6%), mandibular protrusion for Class III case (95.4%), and maxillary retrusion for the severe open bite case (44.6%) were the maximum reported reasons.
The distinction between camouflage and surgical treatment was better made by dentists in Class II and open bite cases than in Class III cases.

Quality assessment is an essential part of orthodontic treatment. Most of the current indices are essentially based on occlusal assessment. However, an ideal occlusion is only one aspect of an ideal treatment. The aim of this article is to introduce a new prioritized commitment-based clinical assessment (PCCA) method and present its reliability and linear correlation test in comparison with the comprehensive clinical outcome assessment (CCA).
One hundred treated cases were scored with the conventional assessment tool--the CCA--and the newly developed assessment tool--the PCCA--with 2 calibrated examiners at 2 different time intervals. These cases were randomly selected including equal numbers of the main malocclusions managed with fixed conventional edgewise appliances within the past 3 years and had complete pre-treatment and post-treatment routine records. The intraclass correlation coefficient (ICC) was used to assess the intra- examiner repeatability of the total scores of both methods. Pearson's correlation coefficients were computed to assess the linear relationships between the CCA and PCCA scores.
The intra-examiner reliability assessed for CCA and PCCA showed high repeatability for both examiners (ICC 0.93 and 0.945, respectively). The inter-examiner reliability values for CCA and PCCA, assessed by ICC, were 0.84 and 0.96, respectively. The linear correlation between the 2 methods, assessed by comparing the mean score of each case by the 2 examiners was significant, at 0.01.
The PCCA method can be used for quality assessment in treated orthodontic patients. The preliminary test of the new method presented good inter- and intra-observer agreements and a significant linear correlation with the CCA method.

The purpose of this study is to assess the effects of rapid maxillary expansion on metabolic activity in the temporomandibular joints of young adult patients using scintigraphy.
The images belonging to temporomandibular joints were obtained from the retrospective scintigraphic records taken from 17 adult females (16.1 and 18.8 years of age and the mean age was 17.3±0.86 years) who had non-functional bilateral posterior crossbite, deep palatal vault and dental crowding, and had been treated with rapid maxillary expansion. Bone scintigraphy images were collected at three-time intervals at the beginning of treatment (T1), during the opening of the mid palatal suture (T2), and at the end of screw activation (T3). Alteration in bone activity in the temporomandibular joint regions were evaluated in sagittal and transaxial slices. To determine the differences between the intervals, repeated analysis of variance and Bonferroni multiple comparison tests were applied.

The mechanical plaque removal methods of removable orthodontic appliances (ROAs) may damage the appliance surface and may not effectively eliminate the entire microbial plaque.
This study aimed to compare the efficacy of brushing + denture cleanser tablets, brushing + propolis mouthwash and brushing only for plaque removal from each orthodontic appliance surface. This crossover randomized clinical trial evaluated 32 patients between 7-15 years with ROAs. The patients were randomly assigned to three groups of brushing (control), brushing + denture cleanser tablets (intervention group 1), and brushing + propolis mouthwash (intervention group 2). The plaque removal methods were switched among the groups during three 1-month periods. One month after practicing a certain protocol, the plaque disclosing agent was applied on the surface of the appliance. The photographs of appliances were analyzed by Image J software to calculate the surface area occupied by the residual microbial plaque.
The ratio difference of residual plaque surface area to the surface area of the entire appliance was significant between the intervention group1 and control group (p<0.001), while it was not significant in intervention group 2 and control group (p=0.105). Also, this difference between the intervention group1 and 2 was statistically significant (p<0.001).
Simultaneous use of toothbrush with denture cleanser tablets decreased the microbial biofilm on the surface of ROAs, compared with brushing alone. Thus, it seems that the use of denture cleaning tablets may be suitable for effective cleaning of ROAs.

To compare Streptococcus mutans colonization between low-friction elastomeric ligatures and to correlate microbial colonization levels with the surface roughness status.
The study included 160 premolars of 10 patients. During the study period, which consisted of 4 sessions each lasting 4 weeks, the ligature types Slide™ Low-Friction Ligature (Leone, Firenze, Italy), Tough-O Energy™ (Rocky Mountain Orthodontics, Denver, USA), and Sili Ties™ (Dentsply Sirona, Surrey KT13 0NY, UK), and steel ligatures (American Orthodontics, Sheboygan, USA) as a control, were fixed to the premolar teeth by clockwise rotation among the jaw quadrants. The plaque index (PI) and gingival index (GI) were obtained before bonding (T0), 6 weeks after bonding (T1), and subsequently every 4 weeks (T2, T3, T4). Presence of S. mutans was analyzed by real-time polymerase chain reaction at T1, T2, T3, T4. Surface roughness was evaluated with Atomic Force Microscopy (AFM) before ligation (Ra0) and after (Ra1) ligation. The paired t-test, ANOVA, repeated measures of ANOVA, and the Kruskal-Wallis test were used for the statistical analysis.
S. mutans colonization was significantly higher on the Slide group (P < .05). The lowest Ra0 was seen in Slide and the highest was seen in the Tough-O Energy group. check details There was no correlation between S. mutans colonization and Ra1 parameters of elastomeric groups (P > .05).
S. mutans colonization showed variations in low-friction elastomeric ligatures independent of surface roughness. Ringshaped low-friction elastomeric ligatures were not different from the steel ligature in terms of S. mutans colonization.

To compare the skeletal and dental effects of twin-block appliances with or without expansion.
From our archives, patients using twin-block appliances were selected. A total of 20 patients with expansion screws were classified as group 1 (10 male, 10 female; mean age 12.48 ± 1.38 years), and 18 patients without screws as group 2 (8 male, 10 female; mean age 12.81 ± 1.16 years). Cephalometric radiographs at pre-and post-treatment were used to evaluate skeletal and dentoalveolar parametric changes; study models and posteroanterior radiographs were used for transverse evaluation. The initial measurements and the treatment-related mean changes within the study groups were analyzed using the Student's t-test.
Changes in maxillary skeletal measurements were not statistically significantly different between groups except for A-VRL (P > .05). Mandibular measurements showed an increase in SNB (º) and Co-Gn distance in both groups. However, these changes were similar for both groups (P > .05). The maxillary measurements showed that incisors were proclined in the expansion group and retroclined in the non-expansion group. No significant difference was found between the groups in terms of changes in the skeletal transversal measurements (P > .05). On the study models, the changes in maxillary intercanine and intermolar widths, and in arch length differed to a statistically significant degree between groups (P < .05).
The skeletal effects of 2 different types of twin-block appliances in the transversal direction were similar; it was determined that dental expansion was obtained in the maxilla by adding screws to the twin-block appliances.

It may be primary when it is confined to the CNS or secondary in the context of systemic inflammatory conditions such as systemic lupus erythematosus, rheumatoid arthritis, or infections. However, there is no known association with axial spondyloarthritis. Herein, we present the case of a 37-year-old man, with axial spondyloarthritis treated with infliximab for 9 years, who presented with persistent fevers, elevated inflammation markers, lateral medullary syndrome, and right-sided hemiparesis. Magnetic resonance imaging of the brain demonstrated multiple cerebral infarcts. Examination of cerebrospinal fluid showed mild lymphocytic pleocytosis and protein elevation. Digital subtraction angiography and transcranial ultrasonography of the cerebral blood vessels revealed luminal narrowing of the basilar and the left posterior cerebral artery. The diagnosis of CNS vasculitis was made and intravenous methylprednisolone and cyclophosphamide pulses were administered, leading to fever remission with gradual improvement and resolution of the neurological manifestations.
Behçet's syndrome (BS) is a multisystem variable vessel vasculitis characterized by skin-mucosal lesions. It can also involve the eyes, blood vessels, joints, gastrointestinal system, urogenital system, and central nervous system. BS starts in the third or fourth decade and affects both genders equally. The disease is more severe in young men. Although the sensitivity of the pathergy test (PT) is decreasing today, it is still an important clue in the diagnosis of BS. We describe the characteristics of BS in our region, retrospectively. We also analyzed the effect of gender, age, family history, and skin PT positivity status on the difference of clinical involvement.
A total of 777 BS patients (391 women and 386 men; 40.0 ± 11.6 years old) who applied to our Rheumatology Department between January 2010 and June 2020 were included in the study.
Of the 777 patients, 391 were female (50.3%) and 386 were male (49.7%). The mean age at diagnosis was 30.3 ± 9.8 years. The proportion of patients with BS in their family was 10.
