Dental arch dimensions are important considerations in orthodontic treatment planning and monitoring.

This study aimed to compare the dental arch dimensions in wind and non-wind instrument players (WIP and non-WIP).

This was a cross-sectional study which compared a group of 50 male subjects aged 18-45 years that had been playing wind instruments for a minimum of 2 years with a control group matched for age in the same environment. The arch dimensions were assessed for both groups by measuring their dental casts using a digital caliper. Data was analyzed using statistical Software Package for Social Sciences (SPSS Inc, Chicago, IL) version 17. Statistical significance level was set at P < 0.05.

The mean number of years of playing wind instrument among the WIP was 9.26 ± 6.21 years. All the maxillary arch dimensions were larger in the WIP group except for the palatal depth while the mandibular arch parameters in the non-WIP group were larger than the WIP group except the mandibular arch length. The differences were not statistically significant (P > 0.05). The mean maxillary inter-canine width (37.48 ± 1.12 mm), inter-molar width (57.27 ± 1.99 mm), arch length (29.80 ± 2.2.09 mm), and palatal depth (22.21 ± 2.33 mm) for class B instrument (Saxophone and clarinet) players were larger than either the class A instrument (Trumpet and trombone) players or the non-WIP group. These differences were not statistically significant (P > 0.05).

Playing a wind instrument as well as the type of instrument played, duration, and frequency of play did not significantly affect dental arch dimensions.

Bimaxillary protrusion is a condition wherein esthetic concerns are the main reason behind seeking orthodontic treatment.

The aim of this retrospective cephalometric study was to evaluate the soft tissue profile and dental changes among female Saudi bimaxillary protrusion patients treated with extraction of all second premolars followed by retraction of the anterior teeth. Subjects and Methods Pre and posttreatment cephalometric radiographs of adult female patients (ages 18-30 years) who underwent orthodontic therapy for Class I bimaxillary protrusion were obtained. Data were analyzed with SPSS
software. A paired t-test and Pearson's correlation coefficients were conducted with the statistical significance set at 95% (P value < 0.05).

At posttreatment, there was an overall decrease in the mean values among the majority of the soft tissue and dental cephalometric angles and linear measurements. Among soft tissue variables, there was a marginal increase in the upper lip length by 1.49 mm (P < 0.00) was observed among the dental variables. Conversely, no significant changes were noted in the lower incisors. Pearson's correlation analysis revealed a significant correlation between all the different dental variables. Within the soft tissue variables, there was a significant positive correlation between changes in the upper lip protrusion, lower lip protrusion, upper lip thickness, and the distance from the upper and lower lips to the S-line.
Contamination is a common problem in pediatric restorative dentistry and there are a few studies that investigate blood contamination, hemostatic agents, and tooth dentin.

The purpose of this study was to evaluate the effects of blood contamination and hemostatic agents on the bond strength of two different bonding systems with the dentin of primary teeth.

Buccal and lingual dentin surfaces of 40 primary second molar teeth were used for this study. Specimens were divided into 4 groups according to the contamination and hemostatic agents (Blood-B, Ankaferd Blood Stopper-A, ViscoStat-V, Control-C) and then every group was further divided into two subgroups according to the bonding systems (Clearfil SE Bond-I, All Bond Universal-II, n = 10 per group). A bulk-fill composite resin was built-up on the surfaces. The specimens were tested in the micro shear mode at a crosshead speed of 1 mm/min on a universal test machine. Statistical analysis was performed with ANOVA and Tukey's tests at P < 0.05.

Significant differences have been detected in the micro shear bond strengths only between the Ankaferd Blood Stopper (ABS) (AI = 13.72 ± 4.47 and AII = 9.12 ± 4.4) and control groups (CI = 22.78 ± 10.86 and CII = 16.49 ± 6.55) without regards to the bonding systems. The highest scores were obtained in the control groups. Clearfil SE Bond showed better performance than All Bond Universal in all groups.

It was determined that only the ABS contamination groups showed statistically significant decreases in the bond strengths when compared with control groups.

The purpose of this study is to compare the thickness and elasticity of the masseter muscle before and after orthognathic surgery in patients with class III skeletal deformity and to investigate the relationship between the sonographic changes in the masseter muscle and the amount of mandibular setback.

The study group consisted of 14 patients with skeletal class III malocclusions who had orthognathic surgery. The control group consisted of 14 patients who had dental and skeletal class I occlusion. Muscle thickness measurements were performed with B-mode and high-frequency linear scanning probe of the ultrasound device. Elastography feature and muscle hardness ratio were obtained by applying compression and decompression on muscles at rest and during maximum contraction in the transverse plane. Patients were categorized into two groups according to the mandibular setback as <5 mm and ≥5 mm.

The masseter muscle thickness after surgery was found statistically increased bilaterally in both at rest and during contraction for the study group (P < 0.
