RESUMO
Abstract Objective: To evaluate in vitro erosive effect of analgesics on primary tooth enamel. Material and Methods: The pH and the titratable acidity measurements of the medicines were performed in triplicate using a digital pH meter. Enamel slabs of primary teeth flat and polished were selected by initial surface microhardness analysis. Medications were selected and specimens were assigned into five groups (n=12): Dalsy; Magnopyrol; Paracetamol; Tylenol; and distilled water (negative control). Specimens were immersed in 5 ml of each group solution for 30 min, 4x/day for three days and stored in artificial saliva at 37 °C between immersions and at night. Final microhardness was determined. The data were submitted to Oneway ANOVA and Tukey's test. Scanning electron microscopy (SEM) analysis was performed in three specimens of each group. Results: Medicines showed acidic pH and mean values of titratable acidity ranged from 1.46 to 11.66 ml of 0.1N NaOH. The mineral loss of Magnopyrol was statistically significant in relation to the control group (p<0.01). Magnopyrol showed higher values when compared to Tylenol (p<0.05). SEM images displayed microstructure alterations in the Paracetamol group. Conclusion: Despite the low pH values, only Magnopyrol showed greater enamel softening. Paracetamol demonstrated morphological changes in primary tooth enamel (AU).

Dental enamel defects (DED) are lesions that occur due several factors. Proper care is needed to promote their treatment and prevention. The aim of this study was to evaluate the occurrence of DED in permanent teeth of children who used antimicrobial drugs in the first four years of life. This is a crosssectional study carried out in a Primary Health Care (PHC) service, which included children from six to 12 years of age. DED were evaluated by oral examination, and data on the use of antimicrobials in early childhood were collected based on medical records. Data were analyzed with the chi-square test and Fisher's exact test. The sample included 144 children. In relation to DED, 50% (72) and 20.1% (29) presented opacity and hypoplasia, respectively. Amoxicillin was the most frequently prescribed drug, followed by sulfamethoxazole + trimethoprim. Among the children, 78.5% (113) were prescribed antimicrobial drugs at least once during the first 4 years of life, and 55% (79) of them presented some type of DED. There was no statistically significant association between the variables analyzed. In conclusion, there was high prevalence of children with DED, and amoxicillin was the most commonly prescribed antibiotic.

Abstract Objectives: to investigate the prevalence of dental anomalies in complete deciduous dentition of children with NSCL/P. Methods: this study included 75 children with NSCL/P and 286 healthy control. In both groups the children had deciduous dentition with ages varying from 4 to 6 years. Clinical examination, panoramic and periapical radiographies were performed and dental anomalies of number and shape were considered. Results: there was a higher prevalence of dental anomalies in the case group, compared to the control group. In all, 42 dental anomalies were identified, 25.33% in the case group and 8.04% in control group (p<0.001). Therewas a higher frequency of dental anomalies in NSCL/P (47.36%), followed by non-syndromic cleft lip (31.57%) and non-syndromic cleft palate (21.05%). The occurrence of agenesis (p= 0.005) and twinning (p = 0.029) were higher in the case group. Conclusions: the occurrence of agenesis and dental twinning was more frequent in the case group and may contribute to the definition of oral cleft subphenotype.

Abstract Objective: To determine the frequency and characteristics of mesiodens in Indian school children. Material and Methods: 1232 radiographs of patients attending the Department of Oral Medicine and Radiology of the age group of 4-15 years studied for the present retrospective study. The intraoral periapical radiographs and occlusal radiographs of the premaxilla were examined to determine the presence of mesiodens. The data regarding the presence of mesiodens, number, position, location on the arch, shape and associated complications were recorded. Results: Eleven patients had 14 mesiodens, with a frequency of 0.8%. The ratio of boys to girls was 1.2:1. Maximum mesiodens observed in the age group of 7-9 years. Most of the mesiodens were conical in shape and found on the palatal side. Fifty percent of the mesiodens were unerupted. The majority of patients (57.1%) had vertically positioned mesiodens. Midline diastema was the most common complication due to mesiodens (66.7%). Conclusion: Routine check-up during the primary dentition and mixed dentition stages helps for early detection of mesiodens and thus preventing complications. Early identification is useful for planning comprehensive management, initiating proper consultation and referral for evaluation and treatment.

OBJECTIVE: Developmental defects of enamel (DDE) in preterm infants still require clarification and may favour dental caries, lower food intake and greater difficulty with weight-height gain. We evaluated factors associated with DDE in preterm infants. SUBJECTS AND METHODS: In this prospective cohort study, we monitored 54 prematurely born infants from birth to 24 months of age. Trained and calibrated dentists examined the oral cavity of these children to identify and categorize DDE. Information on perinatal variables was collected from the infants' medical records and interviews with their mothers. The data were analysed using Student's t test, a chi-squared test and Pearson's product-moment correlation coefficient. RESULTS: A total of 46.3% of the 54 children presented DDE, which was observed more frequently in the left hemiarch in children born extremely (<28 weeks of gestation) or very preterm (28 to <32 weeks; RR = 2.2; 95% CI 1.3-3.6), with very low birthweight (<1,500 g; RR = 2.0; 95% CI 1.1-3.5), who were admitted to the neonatal intensive care unit (RR = 1.3; 95% CI 1.0-1.7), and who were intubated (RR = 1.6; 95% CI 1.1-2.2). CONCLUSIONS: The high incidence of incisor enamel defects, particularly on the left side, was related to higher risk prematurity and to local trauma from intubation.

La alveólisis es una condición poco frecuente y asintomática. Se produce cuando la raíz del diente primario se vuelve susceptible a la presencia de placa bacteriana y a la formación de cálculos, impidiendo el proceso de cicatrización espontánea de la lesión, causando inflamación e irritación de la mucosa circundante. Las principales causas de la alveólisis son la caries dental y el trauma dentoalveolar. El tratamiento de la alveólisis, generalmente se indica la extracción inmediata. El presente casotrabajo tiene como objetivo describir un reporte de caso de una paciente de género femenino, de 5 años de edad, que presentó alveólisis en el diente primario 51, el cual fue extraído y presentó proceso de cicatrización normal con erupción del diente sucesor 11 sin alteraciones. Cabe al cirujano dentista la búsqueda por informaciones sobre esta patología, saber identificarla y tratarla precozmente, para así mejorar significativamente la calidad de vida de la paciente infantil.
A alveólise é um condição não muito frequente e assintomática. Ocorre quando a raiz do dente torna-se suscetível à presença de biofilme e formação de cálculos, impedindo o processo de cicatrização espontânea da lesão, causando inflamação e irritação da mucosa circundante. As principais causas da alveólise são a cárie dentária e o trauma dentoalveolar. O tratamento da alveólise, geralmente é a exodontia do elemento dentário afetado. O presente trabalho tem como objetivo apresentar um relato de caso de uma criança do gênero feminino, de 5 anos de idade, que apresentou alveólise no elemento dentário 51, o qual foi extraído e apresentou processo de cicatrização normal com irrompimento do elemento 11 sem alterações. Cabe ao cirurgião-dentista a busca pelas informações sobre essa patologia, sabendo identificá-la e trata-la precocemente, para melhorar significativamente a qualidade de vida da criança.
Alveolysis is an asymptomatic and infrequent condition. It occurs when the root of the tooth becomes susceptible to the presence of biofilm and formation of calculi, preventing the process of spontaneous wound healing, causing inflammation and irritation of the surrounding mucosa. The main causes of alveolysis are dental caries and dentoalveolar trauma. In the treatment of alveolysis, immediate exodontia is usually indicated. The present study aims to present a case report of a 5 - year - old female child with alveolysis of primary tooth 51, which was extracted and showed a normal healing process with eruption of successor tooth 11 without alterations. It is up to the dentist to search for information about this pathology, knowing how to identify it and treat it early to significantly improve the child's quality of life.

Objective: To analyze the chronology of first deciduous tooth eruption in children with microcephaly associated with presumed or confirmed Zika virus. Material and Methods: A longitudinal study was developed with 74 children of both sexes. Data on prematurity, gestational age (in weeks), anthropometric characteristics at birth [length (cm), weight (g) and cephalic perimeter (cm)] and dental eruption (chronological age and corrected age for prematurity in months) were collected and presented through descriptive statistics. Data was analyzed using the Statistical Package for Social Sciences. Results: The majority of children were female (54.1%) and 14.9% were born premature. The mean gestational age was 38.2 (± 1.9) weeks, while length, weight and cephalic perimeter at birth were 45.6 (± 3.1) cm, 2750 (± 526.6) and 30 (± 2.3) cm, respectively. The eruption of the first tooth occurred on average at 12.3 (± 3.0) months of chronological age and at 11.1 (± 2.3) months of corrected age. The first erupted teeth were the lower deciduous central incisors (82.4%). The mean age for dental eruption in males was 12.5 months (± 3.0) and in females 12.0 months (± 3.1) among full-term children. For premature infants, the mean corrected age of dental eruption was 11.5 months (± 3.4) for boys and 11 months (± 1.7) for girls. Conclusion: In this group of children with microcephaly, the first tooth to erupt was the lower central incisor around the first year of life. Girls had lower average eruption time when compared to boys in both chronological age and age corrected for prematurity.
