The chronological age estimation of living individuals is a crucial part of forensic practice and clinical practice, such as in orthodontic treatment. It is well-known that methods for age estimation in living children should be tested on different populations. Ethnic affiliations in Brazil are divided into several major groups depending on the region, with the south of Brazil being known for its German immigration. (1) Background: This study aimed to evaluate the correlation between chronological age and dental age using Demirjian's method and Cameriere's method in a group of children from Joinville, South Brazil to investigate if both methods can be used to estimate dental age in this population. (2) Methods: The sample consisted of 229 panoramic radiographs (119 were males and were 110 females) from Brazilian children (ages ranging from 6 to 12 years). The chronological age at the time of the panoramic radiographic exam was calculated for each child. The dental age was estimated according to Demirjian's method and Cameriere's method. All continuous data were tested for normality by using the Shapiro–Wilk test. The Pearson correlation coefficient test was applied. An alpha of 5% (p < 0.05) was used for all analyses. (3) Results: The mean chronological age was 8.75 years. According to Demirjian's method, the mean dental age was 9.3 years, while according to Cameriere's method, the mean dental age was 8.66 years. A strong correlation between chronological age and dental age according to Demirjian (r = 0.776 and p < 0.0001) and Cameriere (r = 0.735 and p < 0.0001) was observed for both genders. (4) Conclusions: Both methods presented a good correlation with chronological age in the studied population and could be used to assess dental age in this population. [ABSTRACT FROM AUTHOR]

Objective: To investigate the association between single nucleotide polymorphisms in the COX2 gene (rs689466 and rs5275) and local and systemic signs and symptoms of teething. Material and Methods: Forty-four pairs of mothers-babies/toddlers were included. Erupted primary teeth were evaluated during clinical examination. Local and systemic signs and symptoms of teething were obtained from mothers' reporting via anamnesis. Samples of buccal cells were retrieved for DNA genotyping using real-time PCR. The T-test, Chi-square test, logistic regression, and haplotype analyses were applied. Results: Almost all mothers (95.5%) reported at least one local or systemic sign and symptom of teething. The most common was increased salivation (79.5%), diarrhea (72.3 %), and fever (70.5 %). The mean number of signs and symptoms per child was higher in boys than girls (mean = 5.1; SD= 1.5; p=0.008). Sleep disturbance (p=0.03) and loss of appetite (p=0.05) were more reported in boys. The rs689466 and rs5275 were not associated with signs and symptoms of teething (p>0.05). Conclusion: The single nucleotide polymorphisms in the COX2 gene (rs689466 and rs5275) were not associated with local and systemic signs and symptoms of teething. [ABSTRACT FROM AUTHOR]

Introduction: Gum is a portion of periodontal tissue that plays an important role in protecting the surface of the teeth. Its migration beyond the boundaries of the cementum enamel junction, exposing the root of the tooth, is called Gingival Recession (GR) which increases susceptibility to root caries, dentin sensitivity, and aesthetic discomfort. Objective: The main goal of this case report is to describe a surgical procedure that combined the technique of subepithelial connective tissue graft and Plasma-rich fibrin for treatment of gingival recession. Case report: A man, 45 years old, leucoderma, attended the Positive University dental clinic complaining that 'his gum was rising, and his teeth were sensitive'. Clinical buccal examination was performed according to international guidelines for periodontal data collection and was the man was diagnosed with GR in the region comprising the buccal faces of the first right upper molar to the first right premolar. Before surgical procedure, 60 ml of blood was collected, and Plasma-rich fibrin was obtained. Subepithelial connective tissue from the donor area was inserted in the receiving area associated with PRF. After twelve months follow up the patient had a gain of keratinized gingiva, root coverage and no signs of inflammation or bleeding on probing. The patient reported no longer dentin sensitivity and was satisfied with the aesthetic result. Conclusion: The association of subepithelial connective tissue graft and PRF demonstrates potential to be used in gingival recession and exposed roots of human teeth treatment.

Introduction: Sotos Syndrome is a dominant autossomic disease caused by a mutation in NSD1 gene localized in chromosome 5. The craniofacial phenotype of Sotos Syndrome is quite distinctive, especially in the young child, and includes macrocephaly, widelyspaced eyes, prominent chin and mandible, high and curved forehead, palpebral slits oblique and downward, long and narrow face. This phenotype plays an important role in the identification of this syndrome. Objective: The aim of this study was to analyze the craniofacial anthropometric landmarks of a young adult male with medical diagnosis of Sotos Syndrome. Material and methods: Using noninvasive method of craniofacial anthropometry, twenty five anthropometric measurements were taken of the individual and compared with the facial pattern of non-syndromic individuals, matched in gender and age. The findings were standards and converted to Z-scores. Results: the data analysis showed that the majority of variables were in supernormal range (greater than +2 standard deviation (SD). None none of them was in the subnormal range (less than –2SD). Conclusion: Anthropometric analysis of Sotos Syndrome demonstrated the usefulness of craniofacial analysis in defining abnormal craniofacial dimensions. [ABSTRACT FROM AUTHOR]
