Introduction: This study evaluated the probability of developing malocclusions in mixed dentition.
Methods: A longitudinal study was conducted with 598 children (aged 5 years) in deciduous dentition. The children were followed for 3 years until mixed dentition (aged 8 years).
Background: The COVID-19 pandemic brought significant changes to dental care, which may have affected pediatric dental care offered in primary healthcare settings. Therefore, the aim of this study was to analyze the quantity of dental procedures performed in primary healthcare for children aged 6 to 12 years, before and during the COVID-19 pandemic.
Methods: This is an ecological study using data from the health information system of Piracicaba, São Paulo, Brazil.
Introduction: This study aimed to investigate the esthetic impact of mandibular crowding and maxillary midline diastema in children in the mixed dentition.
Methods: The sample for this cross-sectional study comprised 785 children, aged 8-10 years, in the late mixed dentition. Mandibular crowding and maxillary midline diastema were evaluated clinically with the Dental Aesthetic Index.
Objectives: The aim of the present study was to analyse the factors associated with self-perceived need for dental treatment among adolescents.
Methods: A representative sample in the state of São Paulo, Brazil, comprising 5558 adolescents, was evaluated in 2015. The adolescents were selected by probabilistic sampling by conglomerates in two stages.
Background: Oral cancer (OC) is among the ten most common cancers and the seventh most frequent cause of death worldwide. It has been reported that these incidence rates are higher in developed country and these mortality rates are higher in less developed areas. So, the objective of the present study was to analyze the spatial joint distribution and to explore possible associations of the epidemiological aspects with mortality rates due to OC in the Brazil.

Methods: The relationship of several independent variables, namely Paulista Social Vulnerability Index (PSVI) score, gender, skin color, family income, age, untreated caries, tooth loss [determined by the Decayed, Missing, Filled-Teeth (DMF-T) index], toothache, periodontal condition [determined by the Community Periodontal Index (CPI)], and malocclusion (maxillary overjet, cross bite, or open bite) affect daily life, measured by the Oral Impacts on Daily Performance (OIDP) instrument.
Background: The aim of this cross-sectional study was to evaluate the impact of oral health conditions, socioeconomic status and use of specific substances on quality of life of alcohol and drug addicted persons, receiving care at outpatient treatment facilities in Brazil.
Methods: A random sample of 262 participants, mean age 37 years, from Psychosocial Care Centers for Alcohol and Drugs (CAPS AD) located in three cities in the state of São Paulo, Brazil, were clinically examined for caries experience (DMFT index) by a calibrated examiner. They were asked to complete a series of questionnaires, including the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), socioeconomic characteristics, and the World Health Organization Quality of Life assessment (WHOQOL), which were considered the outcome variables of the study.
Background: Investigate the individual and contextual variables related to caries in underprivileged adolescents, and the disparity in distribution of the disease.
Methods: Cross-sectional analytical study, conducted in the city of Piracicaba, SP, Brazil, in 2012. The probabilistic sample was composed of 1,179 adolescents from 15-19 years of age, randomly selected from 21 state schools and 34 Primary Health Units--Family Health (PHU-FH).
Objectives: To investigate the effects of a voice education program to teachers on vocal function exercise and voice hygiene and compare a pre- and post-vocal exercise for the teacher's voice quality.
Methods: A random sample of 102 subjects was divided into two groups: experimental group (29 women and seven men) with vocal hygiene and training exercises and control group (52 women and 14 men) with vocal hygiene. Two sessions were held about voice hygiene for the control group and five sessions for the experimental group, one being with reference to the vocal hygiene habit and four vocal exercise sessions.
Objective: To evaluate the association of breastfeeding duration, pacifier use and nasal air flow with occlusal disorders among children.
Methods: This cross-sectional observational study included 138 children aged 4 and 5 years selected in all the daycare centers of the city of Campo Limpo Paulista, Brazil. Questionnaires were applied to mothers to identify total duration of exclusive breastfeeding and non-nutritive sucking.
Objective: To analyze the reproducibility of a calibration trial, at different diagnostic thresholds of dental caries, in a 12-month evaluation.
Methods: A group of dental examiners (n = 11), who had previous experience in epidemiological surveys, participated in the study. An initial training phase (theoretical and clinical) and five calibration exercises (baseline, 3, 6, 9 and 12 months) were arranged.
The present study aimed to compare clinical, fiber-optic transillumination and bite-wing radiographic assessment of carious lesion depth in contacting proximal surfaces with the results obtained by direct visual inspection after tooth separation of the respective surfaces. It is suggested that when a carious lesion is diagnosed as non-cavitated by clinical examination or restricted to enamel by FOTI or radiographic examinations in a population of children with low caries prevalence, dentists should adopt a preventive approach.
