Objective: To investigate the effectiveness of a convolutional neural network (CNN) in detecting healthy teeth and early carious lesions on occlusal surfaces and to assess the applicability of this deep learning algorithm as an auxiliary aid.
Materials And Methods: A total of 2,481 posterior teeth (2,459 permanent and 22 deciduous teeth) with varying stages of carious lesions were classified according to the International Caries Detection and Assessment System (ICDAS). After clinical evaluation, ICDAS 0 and 2 occlusal surfaces were photographed with a professional digital camera.
The aim of the present study was to investigate the impact of oral health literacy (OHL) on conceptions of care and behaviors related to COVID-19. The sample came from two preliminary cross-sectional studies that determined the level of OHL of parents/guardians of six-to-12-year-old children in two major Brazilian cities (Curitiba and Belo Horizonte). Functional OHL was measured using the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) and the Health Literacy Dental Scale (HeLD-14) for the evaluation of interactive OHL.

Methods: A cluster randomized clinical trial was conducted in three phases with an initial sample of 291 male and female adolescents 14-19 years of age. Phase I (n = 288) comprised a clinical examination performed by a calibrated examiner using the simplified oral hygiene index (OHI-S) and gingival bleeding index (GBI).
Social determinants of health (SDH) are strongly associated with oral health outcomes, and oral health literacy (OHL) is a potential factor that can modify this association. This study evaluated the association between SDH and OHL, including functional and interactive dimensions of OHL. The cross sectional study was conducted with 354 adults recruited from public dental clinics in southern Brazil.

Background/aim: Permanent tooth avulsion requires proper management at the time of the accident and parental oral health literacy (OHL) may influence decision-making with regards to dental trauma. The aim of this study was to investigate the influence of OHL on: (1) self-rated comprehension of an information leaflet (IL), (2) self-rated capacity to execute the tasks proposed on the IL, and (3) attitudes regarding the avulsion of a permanent tooth in children.
Material And Methods: A longitudinal study was conducted involving the reading of an IL by 466 parents/caregivers.
The aim of the present study was to investigate the discontinuity of oral health care among children and adolescents who accessed emergency services at primary care units and urgent care units. Records were reviewed of patients aged 0 to 17 years treated in the public healthcare system in city of Curitiba, Brazil. Discontinuity was considered when elective treatment was not registered at the primary care unit within six months after urgent care.

Material And Method: FPMs with MIH of 35 patients aged 7 to 16 years were included. The FPMs were randomized into the following two groups: total-etch (TE-37% phosphoric acid etching) and self-etch (SE-no prior etching).
Purpose: To analyse the effect of information technologies on improving the frequency of the use of dental floss among adolescents.
Materials And Methods: A randomised, controlled clinical trial was conducted with 291 adolescents (mean age: 16.1 years) in three phases.
Background: Molar incisor hypomineralization (MIH) is a developmental enamel defect with multifactorial etiology. Although the relationship between celiac disease (CD) and developmental enamel defect was demonstrated, the association between CD and MIH is uncertain.
Objective: The objective of this study was to analyze the occurrence of MIH in CD patients.
Hypomineralized primary second molars (HPSMs) are clinically represented by demarcated opacities in the enamel, involving from one to four primary second molars. The purpose of this cross-sectional study was to investigate the systemic exposures associated with hypomineralized primary second molars. A representative population-based sample of 731 eight-year-old children was randomly selected.

A representative population-based sample of 731 schoolchildren was randomly selected from the public school system in Curitiba, Brazil. Schoolchildren aged 8 years with fully erupted permanent first molars and incisors were eligible for the study.

Methods: This systematic review was performed using published observational studies that evaluated the systemic exposures associated with MIH. The sources of articles searched were PubMed, Scopus, Web of Science, LILACS, BBO, Cochrane Library and Grey literature.
Background: Identifying patients with high levels of DA helps to define the most adequate oral healthcare strategy, especially for pediatric patients.
Aim: To investigate the association between parental reports of dental anxiety (DA) and molar incisor hypomineralization (MIH) in schoolchildren.
Design: A cross-sectional study was conducted in a representative sample of 731 8-year-old schoolchildren from the city of Curitiba, Brazil, who were clinically examined (k ≥ 0.
Background: Molar incisor hypomineralization (MIH) is associated with unfavourable dental conditions such as dental caries and may consequently impact oral health-related quality of life (OHRQoL).
Objective: To assess the impact of MIH on OHRQoL in children with early mixed dentition.
Method: A population-based cross-sectional study of 728 8-year-old children from the public school system in Curitiba, Brazil, was conducted.

Background: Adolescence is a decisive period in the construction of new conduits.
Objective: The influence of an App associated with conventional educational methods in adolescents' oral health.
Study Design: Randomized controlled trial including 291 participants (mean age = 16.
Purpose: The purpose of this cross-sectional study was to evaluate the association between parents' dental anxiety (DA) and independent variables.
Methods: One hundred sixty-eight dyads of parents and six- to 12-year-old children who were undergoing treatment at a university pediatric dentistry clinic were recruited. Two examiners evaluated parents' DA and oral health literacy (OHL) using the Brazilian version of Corah's dental anxiety scale and the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30), respectively.
Purpose: This study evaluated the effect of oral health literacy (OHL) on the retention of health information in pregnant women.
Materials And Methods: A total of 175 pregnant women were randomly assigned to standard oral (spoken), written and control intervention groups. With the exception of the control group, the interventions investigated the eating habits and oral hygiene among children under 2 years of age.
Eating behavior of parents exerts an influence on eating practices among their children, including the consumption of cariogenic products. The aim of this study was to determine the relationship between the snack limits established by parents/caregivers and the prevalence of untreated dental caries (UDC) among their children. A cross-sectional study was conducted with a representative sample of 686 children aged four and five years enrolled at public schools in the city of Curitiba, Brazil, and their parents/caregivers.
