    An evaluation of condylar and ramal vertical asymmetry in adolescents with unilateral and bilateral posterior crossbite using cone beam computed tomography (CBCT)
    (Sciendo, 2014) Halicioglu, Koray; Celikoglu, Mevlut; Yavuz, Ibrahim; Sekerci, Ahmet Ercan; Buyuk, Suleyman Kutalmis
    Aims: The primary purpose was to evaluate condylar and ramal vertical asymmetry in adolescent patients displaying unilateral posterior (UCB) and bilateral posterior crossbite (BCB) malocclusions. A secondary aim was to compare the findings with a matched control group exhibiting normal occlusion (CG) using cone beam computed tomography (CBCT).Material and methods: The study groups consisted of (1) 30 patients (Mean age: 14.49 & PLUSMN; 1.91years) with a UCB, (2) 29 patients (Mean age: 14.57 & PLUSMN; 1.84 years) with a BCB, and (3) 36 patients (Mean age: 14.24 & PLUSMN; 2.42 years) as a matched control group (CG). Condylar, ramal, condylar-plus-ramal height and index measurements were performed using CBCT images following the method of Habets et al. A paired t-test was performed for side comparison in each group. One-way ANOVA (Analysis of Variance) was used to determine statistically-significant differences between the groups for asymmetry index measurements and Tukey's HSD test was employed for individual group differences.Results: There was no statistically significant difference in condylar height (CH), ramal height (RH), and condylar plus ramal height (CH + RH) measurements between the right and left sides of the UCB group and CG, except for the RH in the BCB group (p = 0.045). Tukey's HSD test showed that the ramal asymmetry index (RAI) and the condylar plus the ramal asymmetry index (CRAI) were statistically significantly different between the UCB and BCB groups (p = 0.035 and p = 0.015, respectively).Conclusions: Although the condylar asymmetry index (CAI) values were found to be high in the groups of UCB (13.84 & PLUSMN; 11.33), BCB (9.38 & PLUSMN; 8.56), and CG (10.58 & PLUSMN; 9.48), the comparisons amongst the groups were not statistically significant. The asymmetry between the UCB and BCB groups was observed for RAI and CRAI values, rather than CAI values.

    Forced eruption of palatally impacted maxillary canines with fixed and removable appliances: Case report
    (Cumhuriyet University Faculty of Dentistry, 2011) Halicioglu, Koray; Kiki, Ali; Yavuz, Ibrahim; Baydas, Bülent
    Eruption anomalies of maxillary anterior teeth are clinical problem which effects facial esthetics. Forced eruption and alignment of impacted teeth into the arch is the best treatment approach and supply a more esthetic smile for patient. For this purpose, clinician should be selecting the best ideal orthodontic mechanics. In this study presented that orthodontics and surgery treatment options was evaluated used for forced eruption of palatally impacted maxillary canines and on two cases that is forced eruption of palatally impacted maxillary canines used with fixed and removable orthodontics mechanics and explain that advantages and disadvantages of this mechanics. In the present two case explained new method that is an effective and simple removable appliance for the forced eruption of impacted teeth which included retention clasps and a helical spring.

    Medical profits of the rapid maxillary expansion: Literature review
    (Cumhuriyet University Faculty of Dentistry, 2011) Halicioğlu, Koray; Kiki, Ali; Yavuz, Ibrahim
    Rapid maxillary expansion (RME) is a orthodontic treatment procedure which has been routinely used to correct transversal maxillary skeletal constriction. RME not only expands the constricted maxilla, but also results in an increase in nasal dimensions and improvement in nasal respiration, normal Eustachian tube functions with stretching in tensor and levator veli palatini muscles and a reduction in the middle ear infections. A lot of authors have informed that RME was effective on the healing of nocturnal enuresis, additionally. The purpose of this article is to review of this literatures related to medical profits of RME.

    Subjective symptoms of RME patients treated with three different screw activation protocols: a randomised clinical trial
    (Sciendo, 2012) Halicioglu, Koray; Kiki, Ali; Yavuz, Ibrahim
    Aims: The purpose of the present study was to evaluate the subjective symptoms of patients during the active phase of rapid maxillary expansion (RME) treatment, and further, to assess the differences between three different RME activation protocols.Materials and methods: The clinical sample consisted of 60 patients (mean age 13.5 years) with maxillary transverse deficiency requiring expansion. The subjects were randomly divided into three groups on which different expansion protocols were performed. An evaluation of the subjective symptoms was carried out by a Numerical Rating Scale (NRS). The patients completed questionnaires after the first, fifth, tenth, twentieth and final activations. A Shapiro-Wilk test was applied to evaluate homogenity; a Kruskall Wallis test was performed for gender-related differences and to compare the different activation schedules. The Wilcoxon test was used to compare the activations at the various time intervals.Results: No gender-related differences were found. Ninety-eight percent of the patients reported pain during RME. There were no specific differences between groups except for the pain perceived at the twentieth activation. In all groups, pain, the sensation of pressure and its duration were highest at the fifth activation. Subjective symptoms tended to decrease after the fifth and tenth activations. Headache and dizziness were minimal.Conclusion: Different activation protocols did not appear to alter subjective symptoms encountered during RME. The majority of the patients undergoing RME suffered pain and pressure sensations especially after the fifth activation.
