Micro-CT evaluation of maxillary first molars: interorifice distances and internal anatomy of the mesiobuccal root
This study aimed to describe the morphometric relationship of root canal orifices on the pulp floor in the presence/absence of mesiobuccal second canal (MB2) in the maxillary first molars and other aspects of its internal anatomy. Sixty-two maxillary first molars were scanned by micro-CT. The presence of the MB2 canal was verified. The distance between the center points of the MB1, MB2, distobuccal (DB), and palatal (P) canal orifices on the pulp floor were measured (MB1-MB2, MB1-DB, MB2-DB, MB1-P, and DB-P). The MB1-P to DB-P ratio was calculated. The distances between the anatomic apex and the MB1 and MB2 apical foramina...

Narratives about a stigma: attributing meaning to the early loss of deciduous teeth on children's caregivers
This study aimed to understand the experience of early loss of deciduous teeth in children's lives, from the perspective of their caregivers. Qualitative case study included 52 caregivers of children from an outpatient service of a public university in the south of Brazil. Early loss of deciduous teeth to trauma or caries was identified through analysis of health records, and afterwards, semi-structured interviews were performed. Textual material was interpreted through the content analysis proposed by Bardin, supported by the ATLAS.ti software. The theoretical perspective of stigma was guided according to the principles o...

Radiographic evaluation of dental anomalies in patients with congenital Zika virus syndrome
Abstract: Numerous studies have reported abnormalities in the development of oral structures in congenital infections that also involve microcephaly. In this context, it is necessary to identify possible dental anomalies of shape and/or number in patients with Zika virus syndrome using radiography. The study population consisted of 35 children born with congenital ZIKV who underwent intraoral radiographic examinations for 24 consecutive months. A modified periapical technique was performed in an occlusal position for the maxilla and mandible. Categorical data were expressed as absolute and percentage frequencies and compar...

Sedentary behavior, unhealthy food consumption and dental caries in 12-year-old schoolchildren: a population-based study
This study analyzed the association between sedentary behavior (SB), unhealthy food consumption, and dental caries amongst 12-year-old schoolchildren. An epidemiological survey was carried out in the five largest cities (> 80,000 inhabitants) of the State of Mato Grosso do Sul, Brazil. Data were collected on decayed, missing and filled teeth index (DMFT), sociodemographic characteristics, SB, unhealthy food consumption, and water fluoridation status. The analysis was based on the theoretical framework established by J Sisson. Structural equation models were performed to test the association of dental caries experience w...

Impact of adopting different socioeconomic indicators in older adults’ oral health research
This study aimed to evaluate the influence of choosing different socioeconomic status indicators in research regarding older adults ’ oral health. This is a cross-sectional study that analyzed baseline data from the Brazilian Longitudinal Study on Aging (ELSI-Brazil). The outcomes were edentulism (n = 9,073) and self-reported oral health (n = 9,365). The following socioeconomic indicators were assessed: individual income, per capita household income, and wealth index. Poisson regression analysis with robust variance was performed to estimate prevalence ratios (PR), with their respective 95% confidence intervals (CI), af...

Efficacy of 1.23% acidulated phosphate fluoride gel on non-cavitated enamel lesions: a randomized clinical trial
Abstract: A randomized controlled parallel clinical trial was conducted to evaluate the efficacy of the association of 1.23% topical professional acidulated phosphate fluoride (APF) gel with oral hygiene and dietary instructions on the arrest of active non-cavitated lesions in permanent, mixed, and temporary dentition in children between 3 and 12 years of age. Ninety-eight caries-active children were randomly divided into two groups: a fluoride gel group (n = 49) and a non-fluoridated gel group (n = 49). Each group received up to eight weekly applications of gel, weekly professional toothbrushing with oral hygiene instruct...

Evaluation of the quality of referral letters: experience of a Brazilian oral medicine service
This study was aimed at analyzing all referrals received by a single oral medicine service in Brazil. Referral letters were classified into poor, regular, good, and excellent based on key items concerning the primary morphology of the lesion, location, diagnostic hypothesis, symptomatology, time of evolution, consistency, size, and limits. A total of 500 referral letters were evaluated, including 271 (54.2%) from a private service and 229 (45.8%) from a public service. Dentists and physicians had written 475 (95%) and 25 (5%) referral letters, respectively. Among the 500 referrals analyzed in this study, the number of regu...

Influence of skeletal class and facial type on nose dimensions in a Brazilian subpopulation: a CBCT study
Abstract: Evaluating factors that may influence the nose dimensions and, therefore, contribute to the singularity of a person, is important for obtaining a precise facial reconstruction (FR) in forensic anthropology. Thus, the aim in this study was to evaluate the influence of sex, skeletal class, and facial type on nose dimensions of Brazilian individuals using cone-beam computed tomography (CBCT) scans. CBCT images of 54 males and 67 females were classified according to skeletal class (class I, II, or III) and facial type (brachycephalic, dolichocephalic and mesocephalic). Linear and angular measurements of the nose were...

A qualitative study on experiences of persons with schizophrenia in oral-health-related quality of life
This study supports that PWS were able to define their needs and had the ability to discuss their oral health and OHRQoL. These finding could be used to support specific interventions for this population to better manage the negative impact of antipsychotics and help them to consult dentists on a regular basis.

Inheritance pattern of molar-incisor hypomineralization
Abstract The aim of this study was to investigate the segregation patterns of molar incisor hypomineralization (MIH) in families, given the evidence that its etiology is influenced by genetics. Clinically, MIH may be detected in parents and/or siblings of MIH-affected children. Our study included children with at least one first permanent molar affected by MIH (proband) and their first-degree relatives (parents and siblings). The participants were examined clinically to detect MIH, according to the European Academy of Paediatric Dentistry criteria (2003). A total of 101 nuclear families (391 individuals) were studied. Prob...
