In this article a case of alopecia areata which developed due to combined headgear is presented. It is aimed to warn the orthodontists about this rarely seen adverse effect of the extraoral orthodontic appliances.

In this study the effect of the growth and development on soft tissue profile of preadolescent subjects with normal occlusion, skeletal class 1 and mesiodivergent structure was investigated. 10 girls, the mean skeletal age being 9.28 +/- 1.58 years and 10 boys, the mean skeletal age being 9.88 +/- 1.80 years were selected. Two standardized lateral cephalometric roentgenographs were taken from all subjects at one year interval. The angular and linear measurements were performed on tracing films. The mean values of these measurements were calculated and statistically evaluated. According to statistical evaluation, the growth and development of the lips and soft tissue chin in both girls and boys were normal and they were in harmony with each other. However in girls the increase of lower lip thickness and in boys the changes of hard and soft tissue pogonion positions were found to be statistically insignificant. In girls, the correlations between the upper lip position and maxillary growth.

The appliance hygiene performance and its relationship with stomatitis lesions were investigated on 124 patients who were using maxillary removable orthodontic appliance. The patients were divided into five groups according to the appliance wearing periods. Appliance hygiene index (AHI) showed no significant difference between the groups except the fifth group and the prevalence of stomatitis was found as 8.9 percent. There was not any significant correlation between the quantity of plaque and the degree of stomatitis.

Functional jaw orthopedics is an orthodontic treatment which uses muscle stimuli developed from the functions and tonus changes of masticatory, tongue, lip and cheek muscles. The functional regulator which is one of the appliances used in this treatment, takes support not from the teeth, but directly from the soft tissues in order to make changes in alveolar bone and teeth.

The FR I appliance, which aims the sagittal, vertical and transversal development of intraoral cavity by keeping away the perioral muscles is used widely in crowded Angle Class I and Class II Division 1 cases. The most active period for Frankel I treatment is the time upper and lower incisors finish their eruption and the posterior deciduous teeth are in their places only for retention. In the 11 year old patient treated with FR I appliance for 6 months, the ANB angle decreased by 3.5 degrees and an anterior development of mandible was established. Also a transversal development in lower and upper jaws and sagittal development in the lower jaw were seen.

The aim of this study is to evaluate the effect of cervical headgear on point B. The study depends on 40 lateral cephalometric films of 20 cases. 10 Class II, 1 cases had undergone cervical headgear therapy (Treatment group) and 10 Class II, 1 cases had received no treatment (Control group). 4 angular and 5 linear measurements were made on the films. By comparing the treatment and control groups, the changes related to growth was eliminated and the following results were obtained; According to SNB angle there was a statistically significant (p less than 0.05) difference between the two groups. SNB angle increased more in the treatment group. But in a measurement which was made to see the linear difference on point B, there wasn't any statistically significant difference between the two groups.

FR III is a functional regulator appliance developed by Professor Rolf Frankel. This appliance is used in the treatment of Class III malocclusions. Optimum treatment results can be achieved when the appliance is used in the early mixed dentition period. The restricting effect of the buccinator and orbicularis oris muscles on maxillary skeletal development is prevented by means of lip pads and vestibular shields, thus maxillary development is stimulated. In this article philosophy, construction and clinical management of the FR III appliance will be described and two of our patients which are treated with this appliance will be presented.

In this paper a case showing idiopathic hypoparathyroidism with its rare dental findings were presented. Abnormalities belonging to maxillo-facial skeletal morphology was also evaluated by means of cephalometric analysis.

The aim of this study is to evaluate the changes occurring in facial profile in individuals treated with activator and activator + occipital headgear. Our study is based on two treatment groups namely activator and activator + occipital headgear and one control group which received no orthodontic treatment. In each group there were 18 individuals of which 108 lateral cephalometric films were obtained reflecting before and after treatment/control periods. In this research 18 measurements were made. According to the results, it is found out that there exists difference in treatment groups in terms of the movement of lips related to Steiner soft tissue line.

The aim of this research is to evaluate the treatment results of Class II, Division 1 cases whom were treated by Frankel's function regulator (FR-1b). Ten orthodontic patients participated to this research Class II, Division 1 malocclusion was present on all of our patients. On the other hand another group consisting of ten individuals who have Class II, Division 1 malocclusion were chosen as control group. The lateral cephalometric radiographs were obtained at the treatment group before and after the treatment. For the control group same radiographs were obtained at the beginning and 2 years later. As a result we found out that the orthopedic effects of Frankel appliance is limited on both upper and lower jaw. Appliance basically affects the dento-alveolar structures.
