Dental erosion is a pathological condition resulting from the irreversible dissolution of the mineralized portion of the teeth, being recognized in modern society as an important cause of loss of tooth structure. The aim of this study was to assess the prevalence and its association with diet in Brazilian adolescents of Campina Grande, PB, Brazil. A population-based study was conducted on a stratified sample of 675 adolescents aged from 15 to 19 of both sexes using the index proposed by O'Sullivan. Dental examinations were performed by two calibrated dentists (kappa = 0.82). The significance level adopted was 5%. The prevalence of dental erosion was 21%, and the upper central incisors and lateral incisors were the most affected elements, with 50.5% and 40.2%, respectively. The buccal surface showed greater impairment (51.4%) and 67.8% of teeth with dental erosion had more than half of the surface of affected area. Most damage was on the enamel (93.5%). There were no statistically significant differences between the occurrence of dental erosion and gender, age, socioeconomic status, self-reported ethnicity, and diet. There was high prevalence of dental erosion in its early stages among adolescents and there were no significant differences in the frequency of the consumption of foods and beverages and the presence of dental erosion.

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.

Background The eruption of primary teeth represents a stage of many challenges for parents. Aim To investigate the occurrence of signs and symptoms related to the eruption of the primary dentition in children with congenital Zika syndrome. Design Longitudinal study developed with 79 children followed up for a period of 24 months. Data on sex, gestational age, low birthweight, microcephaly, signs and symptoms related to the dental eruption phase, and use and type of medication were collected. Data were presented by descriptive and inferential statistics (chi‐square test). Results The majority (94.9%) exhibited simultaneously two or more signs and symptoms related to dental eruption. Increased salivation (91.1%), irritability (86.1%), and gingival itching (83.5%) were the most commonly reported signs and symptoms. Bivariate analysis showed association between elevation of body temperature and sex (P < 0.05). Almost two‐thirds of mothers (63.3%) reported using medication to relieve symptoms presented by the child; however, the use of topical medication prevailed (57.1%). Conclusion All children with congenital Zika syndrome presented manifestations related to the eruption of primary teeth, with increased salivation, irritability, and gingival pruritus. The use of ointments and gels was the option of mothers in the treatment of the oral discomfort presented by infants.

Congenital Zika Syndrome (CZS) is a condition that has emerged only recently, bringing together multiple changes, including significant changes in the stomatognathic system, which may compromise sucking behavior and consequently the breastfeeding practice. e aim of this study was to investigate the breastfeeding behaviors in children with CZS. A longitudinal study was carried out in two reference centers in Northeastern Brazil. e nonprobabilistic sample consisted of 79 children diagnosed with physical, neurological, and behavioral alterations compatible with CZS. Information regarding the child, nutritive, and nonnutritive sucking behavior and changes related to the sucking reflex was collected. Data were presented through descriptive and inferential statistics. In the bivariate analyses, the chi-squared test was used and 5% significance level was adopted. e majority of children had severe microcephaly (59.7%). Breastfeeding was performed at birth in most of CZS children (89.9%) but only 36.6% of them presented exclusive breastfeeding in the six months of life. Bottle feeding and pacifier were used in 89.9% and 55.7%, respectively. Sucking and swallowing difficulties and occurrence of gastroesophageal reflux were observed in 27.8%, 48.0%, and 29.2% of children, respectively. Early weaning was associated with bottle feeding (p � 0.005) and pacifier sucking (p � 0.003). Although breastfeeding practice at birth constitutes a behavior adopted by most of mothers, adherence to this exclusive habit until the first six months of life was low since the children presenting a large number of comorbidities with direct interference in the suction reflex, sucking, and swallowing difficulty.

The aim of this study was to evaluate whether there is an association between risk behavior for eating disorders (EDs) and dental erosion and caries. A controlled cross-sectional study was conducted in Brazil, involving 850 randomly selected female adolescents. After evaluating risk behavior for eating disorders through the Bulimic Investigatory Test of Edinburgh, 12 adolescents were identified with severe risk behavior for EDs and matched to 48 adolescents without such risk. Dental examinations, anthropometric measurements, and eating habits and oral hygiene were performed. Adolescents with high severity eating disorder condition were not more likely to show dental caries (p = 0.329; OR = 2.2, 95% CI: 0.35–13.72) or dental erosion (p = 0.590; OR = 2.33; 95% CI: 0.56–9.70). Adolescents with high body mass index (BMI) were five times more likely to have high severity eating disorder condition (p = 0.031; OR = 5.1; 95% CI: 1.61–23.07). Therefore, high severity risk behavior for EDs was not significantly associated with dental caries and dental erosion. However, high BMI was a risk factor for developing eating disorders and should be an alert for individuals with this condition.

Objective: To evaluate the oral hygiene level and periodontal condition of adolescents aged 15-19 years and socioeconomic factors. Material and Methods: Cross-sectional study with 630 adolescents from public schools randomly selected in the city of Campina Grande, Brazil. For data collection, a form containing socioeconomic variables and those related to oral hygiene was used. The oral hygiene level was measured through the Simplified Oral Hygiene Index (OHI-S) and periodontal condition was evaluated by the Community Periodontal Index (CPI). Data were descriptively and inferentially analyzed using the chi-square test, adopting significance level of 5%. Results: Adolescents were mostly females (59.5%), aged 16 years (32.4%), non-white (77.8%), with family income lower than US $ 612.00 (55.1%), with parental schooling of up to high school (50%). Periodontal condition showed no significant association with any of the socioeconomic factors (p> 0.05). All participants reported using toothbrush; however, the control of interproximal plaque with flossing was reported by only 44.1%, being higher among females (p = 0.028), and its use has been associated with periodontal status (p = 0.026). The oral hygiene level was satisfactory for 59.7% of adolescents, while CPI showed that only 1.6% of them had healthy periodontium and gingival bleeding (34.4%) and presence of dental calculus (37, 8%) were the most prevalent alterations. Conclusion: Adolescents showed satisfactory oral hygiene condition; however, there was a high prevalence of gingival bleeding and dental calculus. Periodontal condition was associated with flossing; however, association with socioeconomic factors was not observed.
