Knowledge of parents/caregivers about the sleep bruxism of their children from all five Brazilian regions: A multicenter study.

Background: Sleep bruxism (SB) is a masticatory muscle activity that affects children. Parents' knowledge is important for its identification and report to dentists.

Aim: To investigate parents' knowledge about SB among their children.

Profile of patients and factors related to the clinical staging of oral squamous cell carcinoma.

Objective: The aim of the present study was to identify the profile of patients diagnosed with oral squamous cell carcinoma (SCC) and factors associated with the clinical stage of the disease.

Materials And Method: A cross-sectional study was conducted with a sample of 293 medical charts of patients with SCC treated at an oncology reference center in the city of Campina Grande (Brazil) between 2000 and 2006. Descriptive and inferential statistics were performed with robust Poisson regression (α=5%).

Influence of sense of coherence on oral health-related quality of life: a systematic review.

Purpose: The aim of the present study was to perform a systematic review of the literature for scientific evidence regarding the association between a sense of coherence (SOC) and oral health-related of quality of life (OHRQoL).

Methods: Electronic searches were performed in five databases. Manual searches were also performed.

Estimation of toothpaste fluoride intake in preschool children.

The objective of this study was to estimate the intake of toothpaste fluoride used by children aged 2 to 6 years (n=87) treated at a hospital of a medium-sized city (Campina Grande, PB) in the Northeastern region of Brazil. Data regarding sociodemographic characteristics of families and children's toothbrushing were collected from questionnaire-based interviews with parents/guardians, and the amount of fluoride used during toothbrushing was estimated using a precision scale for assessment of the risk of dental fluorosis, considering a cutoff value of 0.07 mgF/kg body weight/day.

Assessment of gingival mucosa of infant rats during teething.

Aim: The aim of the present study was to perform a histological analysis of the gingival mucosa in infant rats undergoing the teething process.

Materials And Methods: Eighteen Wistar rats between 8 and 15 days of life were distributed among three groups: group A--without teething; group B--eruption of incisors; and group C--eruption of incisors and molars. The samples included teeth and periodontal tissue from the region of the incisors and molars of each animal.

Pulp repair after pulpotomy using different pulp capping agents: a comparative histologic analysis.

Purpose: This study's purpose was to histologically evaluate the repair of rat tissue after pulpotomy and covering the pulp tissue with Copaifera langsdorffi oil resin, green propolis extract, fibrin sponge and iodoform-based paste.

Methods: Pulpotomies were performed in the maxillary and mandibular first molars of 21 Wistar rats (84 total teeth). The access cavities were sealed with Coltosol, and histological evaluations were performed at 24 hours, 15 days, and 30 days postoperatively.

Treatment consists of four phases of chemotherapy, the main side effect of methotrexate, the drug most used during the intensification phase, is oral mucositis.

Objective: To evaluate the clinical aspects of the oral mucosa of children with ALL and to determine the effect of 0.

Heterogeneity of metallo and serine extracellular proteinases in oral clinical isolates of Candida albicans in HIV-positive and healthy children from Rio de Janeiro, Brazil.

Candida yeasts frequently cause life-threatening systemic infections in immunocompromised hosts. In the present study, gelatin-SDS-PAGE analysis was used to characterize extracellular proteinases in 44 oral clinical isolates of Candida albicans from HIV-positive (29/50) and healthy children (15/50). Our survey indicates that these oral clinical isolates of C.
