Individual and contextual determinants associated with bullying in schoolchildren eight to ten years of age.

Investigate individual and contextual determinants associated with bullying in schoolchildren eight to ten years of age. A cross-sectional study was conducted with 739 schoolchildren, who answered a question about episodes of bullying related to oral health and questionnaires addressing childhood anxiety and orofacial dysfunction. The guardians provided information on sociodemographic characteristics, sleep disorders, and oral health literacy.

Individual and contextual determinants associated with traumatic dental injuries in children eight to ten years of age: a multilevel analysis.

Objective: Investigate individual and contextual determinants associated with traumatic dental injuries in schoolchildren.

Methods: A cross-sectional study with 739 pairs of parents and children. Parents answered a sociodemographic questionnaire, the Family Adaptability and Cohesion Evaluation Scale and a questionnaire on the child's use of electronic devices.

The effect of sleep disorders, school jet lag, and anxiety in students 8-10 years of age on traumatic dental injuries.

Background/aim: Traumatic dental injuries (TDI) constitute a public health problem. The aim of the present study was to investigate whether sleep disorders, school jet lag, and anxiety are associated with TDI in schoolchildren 8-10 years of age.

Methods: An analytical, cross-sectional study was conducted with 739 pairs of parents/guardians and children enrolled in public and private schools.

Oral health-related quality of life of children before, during, and after anterior open bite correction: A single-blinded randomized controlled trial.

Introduction: One of the goals of malocclusion treatment is to improve the oral health-related quality of life (OHRQoL) of patients. The aim of this trial was to assess the OHRQoL of children before, during, and after anterior open bite (AOB) correction, compared with nontreated children, in a 2-arm parallel single-blind randomized controlled trial.

Methods: Eighty children with AOB aged 8-10 years were randomly assigned to 2 groups (n = 40 each): a group treated with the use of fixed palatal crib (FPC; TG) and a control group (nontreated; CG).

Cross-cultural Adaptation of the Oral Anticoagulation Knowledge Test to the Brazilian Portuguese.

Patients' knowledge about oral anticoagulant therapy may favor the achievement of therapeutic results and the prevention of adverse pharmacotherapy-related events. Brazil lacks validated instruments for assessing the patient's knowledge about treatment with warfarin. This study aimed to perform the cross-cultural adaptation of the Oral Anticoagulation Knowledge (OAK) Test instrument from English into Portuguese.

Probiotic consumption decreases the number of osteoclasts during orthodontic movement in mice.

Methods: C57BL/6 mice were divided in two groups: (1) Probiotic and (2) Vehicle (water). The probiotic (1.

Prospective evaluation of the psychosocial impact of the first 6 months of orthodontic treatment with fixed appliance among young adults.

Objective: To evaluate the psychosocial impact of the first 6 months of orthodontic treatment with a fixed appliance among young adults and compare the results with those of a control group of patients awaiting treatment for malocclusion.

Materials And Methods: A study was conducted with a sample of 120 patients on a waiting list for orthodontic treatment at a university. The participants were allocated to an experimental group submitted to treatment and a control group awaiting treatment.

Oral physiology and quality of life in cancer patients.

Introduction: Cancer treatment can affect the health of the teeth and support structures, which are essential to the chewing process, which may change the nutritional status of the patient.

Objective: The aim of this study was to evaluate the impact of oral physiology changes on quality of life (QoL) of patients submitted to cancer treatment.

Design: Initially 84 cancer patients were screened and only those presenting at least 15 natural teeth were selected for oral physiology and quality of life tests.

Locked mouths: Tooth loss in a women's prison in northeastern Brazil.

Prisoners, in general, exhibit unsatisfactory oral conditions, especially with regard to the large number of missing teeth and with untreated caries. The aim of this study was to assess tooth loss, use of and need for prosthetic rehabilitation, and use of dental services among inmates.

Association between dental erosion and diet in Brazilian adolescents aged from 15 to 19: a population-based study.

Dental erosion is a pathological condition resulting from the irreversible dissolution of the mineralized portion of the teeth, being recognized in modern society as an important cause of loss of tooth structure. The aim of this study was to assess the prevalence and its association with diet in Brazilian adolescents of Campina Grande, PB, Brazil. A population-based study was conducted on a stratified sample of 675 adolescents aged from 15 to 19 of both sexes using the index proposed by O'Sullivan.

Incidence of dental trauma among adolescents: a prospective cohort study.

We estimated the incidence of traumatic dental injuries (TDI) in a 2-year follow-up of adolescents with and without previous dental trauma and verified the hypothesis that individuals with previous trauma are more prone to recurrent TDI events. The present study was developed in three phases. First, a dental trauma cross-sectional study was carried out with 2260 schoolchildren aged 11-13 years in Biguaçu, southern Brazil.
