Genetics and sleep bruxism: a systematic review and meta-analysis of studies with twins.

Objective: To systematically review the literature regarding the concordance of sleep bruxism (SB) between monozygotic (MZ) and dizygotic (DZ) twins.

Methods: The registration for this systematic review was accomplished in the International Prospective Register of Systematic Reviews (PROSPERO, No. CRD42021251751).

Impact of Pulp Necrosis on Oral Health-Related Quality of Life of Children with Early Childhood Caries.

To assess the impact of pulp necrosis on the oral health-related quality of life (OHRQoL) of children with early childhood caries and their caregivers.
A cross-sectional study was performed with a consecutive sample of children who were divided into three groups: (1) caries-free children; (2) with untreated carious lesions and without pulp necrosis; and (3) with untreated carious lesions and at least one tooth with pulp necrosis. Data were collected using a sociodemographic questionnaire, the Early Childhood Oral Health Impact Scale (ECOHIS) and a dental clinical examination using the International Caries Detection and Assessment System index.

Molar-incisor hypomineralization in quilombola children and adolescents: A study of prevalence and associated factors.

Objectives: This cross-sectional observational study determined the prevalence and factors associated with molar-incisive hypomineralization (MIH) in quilombola children and adolescents in north-eastern Brazil.

Methods: The sample consisted of 251 children and adolescents (8 to 14 years old) living in the rural quilombola community Lagoas in São Raimundo Nonato, Piauí (census population). Sociodemographic and health-related data were collected from pre-, peri- and post-natal health records and a clinical examination for MIH diagnosis was performed by four previously trained and calibrated examiners.

Caries, Toothbrushing Habits, and Fluoride Intake From Toothpaste by Brazilian Children According to Socioeconomic Status.

Purpose: The purpose of this study was to evaluate the prevalence of dental caries, toothbrushing habits, fluoride intake, and factors associated with the use of toothpaste in Brazilian children according to socioeconomic status (SES).

Methods: A cross-sectional observational study was conducted with 148 three- to four-year-olds of both low and high socioeconomic status. Data collection consisted of administering a questionnaire to guardians, brushing to determine fluoride intake, and examining the children's teeth to evaluate dental caries.

Endodontic Treatment of Primary Molars with Antibiotic Paste: A Report of 38 Cases.

Objective: This study presents 38 cases of primary molars with necrotic pulps treated with antibiotics-based paste.

Case Report: The technique consisted of necrotic tissue removal of the pulp chamber, using spoons excavators and low speed drills. Pulp cavity was washed with saline solution and dried with sterile cotton balls.

Epidemiologic Study of Molar-incisor Hypomineralization in Schoolchildren in North-eastern Brazil.

Purpose: To determine the prevalence of molar-incisor hypomineralization (MIH) in children and possible factors associated with this disorder.

Methods: This was a cross-sectional observational study of 594 11- to 14-year-olds from Teresina, Piauí, Brazil. The diagnosis of MIH was made based on criteria set by the European Academy of Pediatric Dentistry.

Does Leishmaniasis disease alter the parenchyma and protein expression in salivary glands?

Leishmaniasis is considered a serious public health problem in several regions in Brazil and worldwide. This research aimed to perform a histopathological and proteomic study of parotid, submandibular and sublingual glands of BALB/c mice infected by Leishmania (L) infantum chagasi using histological, immunohistochemical and epifluorescence techniques. Twelve isogenic BALB/c male mice, around six- to eight-weeks old, were separated into two groups: the animals of the control group were injected with 0.

Restorative management of severely ankylosed primary molars.

Severe dentoalveolar ankylosis is an etiological factor for malocclusion. When infraocclusion occurs early, it progresses with time, leading to severe consequences in young children because of compensatory supra-eruption of the antagonist tooth and mesialization of adjacent teeth. Early diagnosis allows for interception of the problem and may prevent orthodontic treatment.

The impact of a dental program for maternal and infant health on the prevalence of dental fluorosis.

Purpose: This study's purpose was to investigate the prevalence of dental fluorosis in children, whose parents had participated in an oral health program when the children were between zero and three years old, residing in a city with fluoridated water.

Methods: Group 1 consisted of 128 eight- to 12-year-olds whose parents had visited a program on at least five occasions when the children were zero to three years old and received education about tooth-brushing and the proper use of fluoridated toothpaste in this young age group. The prevalence of dental fluorosis in the permanent maxillary incisors, using the Thylstrup-Fejerskov index, in Group 1 was compared to that of an age-matched group of children (n=128) whose parents had not participated in the program (Group 2).
