CONTEXT: Symptoms associated with the primary tooth eruption have been extensively studied but it is still controversial. OBJECTIVE:To assess the occurrence of local and systemic signs and symptoms during primary tooth eruption.DATA SOURCES: Latin American and Caribbean Health Sciences, PubMed, ProQuest, Scopus, and Web of Science were searched. A partial gray literature search was taken by using Google Scholar and the reference lists of the included studies were scanned. STUDY SELECTION:Observational studies assessing the association of eruption of primary teeth with local and systemic signs and symptoms in children aged 0 to 36 months were included.DATA EXTRACTION: Two authors independently collected the information from the selected articles. Information was crosschecked and confirmed for its accuracy. RESULTS:A total of 1179 articles were identified, and after a 2-phase selection, 16 studies were included. Overall prevalence of signs and symptoms occurring during primary tooth eruption in children between 0 and 36 months was 70.5% (total sample = 3506). Gingival irritation (86.81%), irritability (68.19%), and drooling (55.72%) were the most frequent ones.LIMITATIONS: Different general symptoms were considered among studies. Some studies presented lack of confounding factors, no clear definition of the diagnostics methods, use of subjective measures and long intervals between examinations.CONCLUSIONS: There is evidence of the occurrence of signs and symptoms during primary tooth eruption. For body temperature analyses, eruption could lead to a rise in temperature, but it was not characterized as fever.

The Root ZX apex locator was accurate in determining in vivo and ex vivo the working length ± 1 mm in primary molar teeth in over 90% of roots regardless of the presence of root resorption.

Background:The COVID-19 pandemic health crisis has changed household and school routines leaving children and adolescents without important anchors in life. This, in turn, can influence their mental health, changing their behavioral and psychological conditions. Aims:To systematically review the literature to answer the question: "What is the worldwide prevalence of mental health effects in children and adolescents during the COVID-19 pandemic?".Methods: Embase, Epistemonikos database, LILACS, PsycINFO, PubMed, Scopus, Web of Science, and World Health Organization Global literature on coronavirus disease were searched. Grey literature was searched on Google Scholar, Grey Literature Report, and Preprint server MedRxiv. Observational studies assessing the prevalence of mental health effects in children and adolescents during the COVID-19 pandemic were included. Four authors independently collected the information and assessed the risk of bias of the included studies.Results: From a total of 11,925 identified studies, 2873 remained after the removal of the duplicated records. Nineteen studies remained after the final selection process.

The objective of this research was to verify the association between verbal bullying and untreated dental caries. The present cross-sectional study had a representative sample of 1,589 children, aged 8-10 years, from public schools. Information on verbal bullying related to the oral condition was obtained through a questionnaire directed to the students. Clinical data were collected by 4 calibrated examiners (kappa > 0.70) using the DMFT/dmft and PUFA/pufa indexes for caries. Socioeconomic issues were answered by those responsible. The prevalence of verbal bullying related to the oral condition was 27%. The results of the Poisson regression, in an adjusted multiple model, showed a significant association between bullying and untreated caries lesions (prevalence ratio, PR: 1.27; 95% CI: 1.07-1.52), PUFA/pufa index (PR: 1.34; 95% CI: 1.11-1.61), pulp involvement (PR: 1.35; 95% CI: 1.09-1.67), and abscess (PR: 1.74; 95% CI: 1.18-2.56). It was concluded that children with untreated dental caries had a higher prevalence of verbal bullying when compared to caries-free or disease-treated children.

Aim To assess the prevalence of self-reported dental pain and its association with sociodemographic, clinical and behavioral/psychosocial indicators among 8- to 10-year-old Brazilian schoolchildren. Design A cross-sectional study was carried out with 1,589 eight- to ten-year-old children randomly selected from public schools of Florianopolis, Brazil. Self-reports of dental pain were collected through a single question as follows: “In the last month, how many times have you had pain in your teeth?” Caries experience was determined by the DMFT/dmft index and its clinical consequences by the PUFA/pufa index. Dental trauma, dental fluorosis and molar-incisor hypomineralization were assessed through the Andreasen, Dean and European Academy of Pediatric Dentistry classifications, respectively. Clinical signs of dental erosion were also observed. Sociodemographic indicators were obtained through a questionnaire answered by the children’s caregivers. Information about behavioral/psychosocial indicators was collected through questions from the Brazilian version of the Child Perception Questionnaire 8–10 years (CPQ 8–10 ). Descriptive analysis, chi-square test, and hierarchically adjusted Poisson regression models were performed. Results 819 children (51.5%) reported episodes of dental pain in the last month prior to the study, whereas 55.6% (n = 509) were girls. The presence of dental pain was significantly associated with sex, trouble sleeping, difficulty eating, school absenteeism, difficulty with paying attention in class, difficulty doing homework, staying away from recreational activities, caries experience, PUFA/pufa index and ulceration (p<0.05). Conclusion The prevalence of self-reported dental pain in 8- to 10- year-old Brazilian schoolchildren was high and was associated with sociodemographic, clinical and behavioral/psychosocial indicators.

Enamel fracture had no significant impact on children's quality of life, while enamel-dentin fracture did have an impact on quality of life.

Background Working length is an important step in primary teeth pulpectomy. Aim To evaluate whether there is a significant difference in the accuracy of electronic apex locators compared to the conventional radiography in working length measurements. Design Sixty‐four children (192 canals) between 5 and 9 years of age with indication for pulpectomy of a primary molar were included after eligibility criteria. A radiographic measurement was obtained from pre‐operative radiography from the cusp tip to the apex or resorption of the root. The electronic measurement was obtained from a complete measurement of the canal with an electronic device up to the apex. Data were analysed with Bland‐Altman plots and Wilcoxon test. Statistical significance was set at P ≤ .05. Results Statistically, there is not any significant difference between radiographic and electronic measurements for the palatal canal or distal canal, as well as mesiobuccal canals (P > .05). Statistically, there, however, is a significant difference between the measurements for the distobuccal canal and mesiolingual canal measurements (P < .05). High internal consistency for both radiographic and electronic methods was achieved (α ≅ 1). Conclusions Electronic and radiographic methods are similar in determining the length measurement of the root canals in primary teeth pulpectomies, except in distobuccal or mesiolingual canals.
