PurposeThe present study is to investigate the effects of type 1 diabetes mellitus on dentition and oral health for children and adolescents.Materials and MethodsThe investigation was carried out on 100 subjects. The first group consisted of 50 subjects with type 1 diabetes mellitus (21 females, 29 males), age 9 ± 0.14 years; In the second group, there were 50 healthy subjects who did not suffer from any systemic disease (25 females, 25 males), age 9 ± 0.11 years. The subjects were evaluated and divided into two groups of 5 - 9 years old, and 10 - 14 years old. The dentition of all participants was examined. Besides, the DFS/dfs index, oral hygiene conditions were evaluated, as well as the plaque index (PI), gingival index (GI) and calculus index (CI). The data obtained from each group were compared statistically.ResultsWhen compared to the non-diabetic group, we observed that dental development was accelerated until the age of 10 in the diabetic group, and there was a delay after the age of 10. The edentulous interval was longer in the group with type 1 diabetes mellitus. This was accompanied by a high ratio of gingival inflammation. Gingival inflammation was 69.7% in the group of 5 - 9 year-old, and 83.7% in the group of 10 - 14 year-old with type 1 diabetes mellitus. Though there was a greater loss of teeth in the group with type 1 diabetes mellitus, there were more caries in the control group. The PI, GI and CI values showed an increase with aging in favor of the group with type 1 diabetes mellitus. There was statistically significant difference in PI, GI and CI between the control and type 1 diabetes mellitus groups for 10 - 14 year-old patients (p < 0.001).ConclusionThe findings we obtained showed that type 1 diabetes mellitus plays an important part in the dentition and oral health of children and adolescents.

This cross-sectional study aimed to evaluate the primary canine and the primary molar relationship in 205 (90 girls and 115 boys) three to six year-old Turkish children with the primary dentition in centric occlusion according to gender and age. In terms of the molar relationship, Class I was represented by 88.29% of all children who agreed to participate in the study, followed by Class II (7.31%), and Class III (4.4%). In terms of the canine relationship, Class I was represented by 87.8% of the sample, followed by Class II (7.8%), and Class III (4.4%). A statistically significant difference was found between age and both the canine and molar relationships (p<0.005), and a positive correlation was confirmed among them. However, the difference and correlation between the gender and the canine and molar relationships were not significant.

The aim of this investigation was to compare the tensile strength, microleakage, and Scanning Electron Microscope (SEM) evaluations of SSCs cemented using different adhesive cements on primary molars.Sixty-three extracted primary first molars were used. Tooth preparations were done. Crowns were altered and adapted for investigation purpose, and then cemented using glass ionomer cement (Aqua Meron), resin modified cement (RelyX Luting), and resin cement (Panavia F) on the prepared teeth. Samples were divided into two groups of 30 samples each for tensile strength and microleakage tests. The remaining three samples were used for SEM evaluation.Data were analyzed with one-way ANOVA and Tukey test.The statistical analysis of ANOVA revealed significant differences among the groups for both tensile strength and microleakage tests (p<0.05).Tukey test showed statistically significant difference between Panavia F and RelyX Luting (p<0.05), but none between the others (p>0.05).This study showed that the higher the retentive force a crown possessed, the lower would be the possibility of microleakage.

Mucoepidermoid carcinoma (MEC), one of the most common salivary gland malignancies, is rare in children. MEC mainly occurs in the parotid gland, along with minor glands being the second common site, particularly in palate. Clinical, histological, and radiological findings of palatal MEC in a 12-year-old girl are presented with three-year follow-up. Pathologic lesions must be considered in differential diagnoses of intraoral asymptomatic lesions, and their detailed inspection should be taken into consideration.

Malocclusions observed in the primary dentition are signs of malocclusions in the permanent dentition.
