ABSTRACT
AIM: Maternal personality traits affect child dental behaviour and have a potential link with dental treatment methods. This study aims to evaluate which maternal personality traits affect child dental behaviour. MATERIALS AND METHODS: Research was carried out upon 60 children aged between 3-12 years, who had been admitted to our clinic for tooth extraction. All children were evaluated by means of the Frankl Behavior Scale (FBS): degrees I and II represent negative behaviours, while III and IV positive behaviour. Thirty children with FBS degree III and IV were assigned to Group I and 30 children with FBS degree I and II were assigned to Group II. Children in Group I underwent tooth extraction with local anaesthesia. Children in Group II underwent tooth extraction under deep sedation. During the first visit, the mothers were tested with the Minnesota Multiphasic Personality Inventory to evaluate personality traits. All mothers in Group I and half the mothers in Group II filled a complete and valid test. RESULTS: Group I and II mothers were compared according to the test results: scores of the Minnesota Multiphasic Personality Inventory (MMPI) test were significantly higher in Group II (p<0.05). CONCLUSION: We hypotetise that character features of mothers of children with negative dental behaviour and positive dental behaviour are different and affect child dental behaviour.

The aim of this study was to investigate changes in hard and soft tissue profile after mandibular setback surgery. Lateral cephalograms of 25 Class III subjects were assessed before and 1.5+/-0.4 years after mandibular setback surgery. Paired t test, Pearson correlation test and linear regression analysis were used to evaluate the changes in soft tissue profile. Significant changes were found in skeletal (SNB -3.6+/-0.9 degrees, ANB 3.7+/-1.0 degrees, overjet 5.0+/-1.2 and overbite 2.5+/-1.1 mm, P<0.001), soft tissue (facial convexity 5.9+/-1.6 degrees, P<0.001; labiomental fold 0.6+/-0.6 mm, P<0.001; upper and lower lip protrusion 0.5+/-0.8 mm, P<0.01; -3.3+/-1.2 mm, P<0.001), and upper and lower lip lengths (0.9+/-1.2mm, P<0.01; -1.8+/-2.1 mm, P<0.001). Correlations were found between facial convexity and SNB and ANB angles and between upper lip length and SNB and ANB angles. The change in lower lip length was correlated with SNB, ANB, overjet and overbite. Lower lip retrusion was correlated with overjet and a significant correlation was found between the retrusion of lower incisor and lower lip. Mandibular setback surgery was effective in producing an orthognathic profile in adult Class III subjects with mandibular prognathism.

The purpose of this investigation was to study the short-term effects of treatment with the Bass appliance by comparative evaluation of treated and untreated skeletal Class II malocclusions. The subjects consisted of forty-seven Class II, division 1 malocclusion cases. Twenty-seven (14 girls, 13 boys) were treated with the Bass appliance for an average of 6 months. The remaining 20 cases (6 girls, 14 boys) served as a control. At the end of the 6 month treatment period the statistically significant treatment changes could be summarized as follows: the sagittal skeletal relationship was improved as a result of favourable growth responses in both the maxilla and the mandible. The overjet was reduced and the molar relationship was corrected as a result of the extended skeletal changes. Distal movement of the upper dentition was evident, with unchanged inclination of the maxillary incisors. Both anterior and posterior facial heights were increased without changes in the inclinations of the palatal and mandibular planes. No significant dental movement was observed in the mandible.

The orthodontic and orthopedic effects of the Activator, Activator-Headgear Combination (ACHG) and the Bass appliance systems were compared by analyzing the cephalometric records of 64 subjects, who were treated for skeletal Class II malocclusion, with both conventional and Pancherz's methods. Differences between observations on the different occasions (starting and ending values) were tested with Wilcoxon's matched pairs rank test. Kruskal-Wallis nonparametric analysis of variance was carried out in different situations among all three groups. If a level of significance less than 0.05 was observed, Scheffè's method of multiple comparisons was used to determine differences among groups. The results of this study showed that greater improvement in sagittal skeletal relationship (ANB angle) was obtained in both Bass and ACHG groups than in the Activator group. The differences between the groups were most pronounced for dental variables. The Bass appliance was found to be more effective in the control of the unwanted side effects (proclination of lower incisors, retroclination of upper incisors). Unfavorable labial tipping of the lower incisors was also prevented with the ACHG appliance.

Craniofacial morphology of children with and without clefts has been reported to differ because of a combination of factors including, morphogenetic pattern, adaptive changes, and lip and palate management. The purpose of this study was to make a cephalometric evaluation of possible differences in craniofacial morphology of Turkish children with and without unilateral cleft lip and palate (UCLP). Twenty UCLP children (7 girls, 13 boys) with a mean age of 10.75 years (SD = 2.58 years) were compared with a control group of children without UCLP, who were matched for age (mean = 10.64 years, SD = 2.58 years) and sex. No patient had received orthodontic treatment. Linear and angular variables were measured from tracings of lateral cephalometric radiographs and the resulting data were evaluated statistically. Compared with children in the control group, the children in the cleft palate group demonstrated a greater flattening of the cranial base, a more retrognathic and posteriorly inclined maxilla with decreased length, a larger mandibular plane and gonial angle, larger anterior facial height, and decreased posterior and upper-posterior facial heights.
