Association of gender, oral habits, and poor sleep quality with possible sleep bruxism in schoolchildren
Abstract The aim of this study was to verify the oral habits, symptoms, and characteristics of some children aged 8 to 10 years that could be associated with possible sleep bruxism. A cross-sectional study was performed. Questionnaires were sent to parents to obtain information on sex, age, school shift, sleep quality, parents ’ perception of children ’ s behavior, and children ’ s oral habits (nail biting, object biting, and lip biting), and symptoms such as headache or earache. In addition, parents reported the frequency of sleep bruxism (no day to 7 days a week). Descriptive analysis and multinomial logistic regr...

Hydrofluoric acid concentration, time and use of phosphoric acid on the bond strength of feldspathic ceramics
The objective of this study was to evaluate the influence of hydrofluoric acid (HF) concentration, etching time, and application of phosphoric acid (PA) followed by neutralization with sodium bicarbonate on the bond strength between a feldspar ceramic and resin cement. Thus, 80 blocks (10 x 12 x 2 mm) of glass ceramic (VM - Vita Mark II - Vita Zahnfabrik) were made and randomly assigned to eight groups (n = 10) according to the factors: HF concentration (5 and 10%), etching time (60 and 120 s), and use of phosphoric acid (PA) (with and without). According to the experimental group, 37% PA (Condac, FGM) was applied after HF...

System dynamics modeling for tooth decay treatment in Brazilian children
Abstract Prevention and health promotion are considered important strategies to control oral diseases. Dental caries is preventable disease and remains the most common chronic disease that affects mainly low income children and still considered the main cause of tooth loss in adulthood in Brazil. The aim of this study is to present a System Dynamics model (SDM) specifically developed with the Stella Architect software to estimate the cost and clinical hours required to control the evolution of dental caries in preschool children in Maring á, Brazil. Two main strategies to control caries were considered in the model: the a...

Prevalence of horizontal alveolar changes in edentulous patients: a retrospective tomographic study
Abstract Horizontal bone loss after tooth extraction is a common finding that demands bone reconstruction in various cases. The aim of this study was to assess the horizontal alveolar status in partially and completely edentulous patients using cone-beam computed tomography (CBCT). In total, 1516 CBCT scans of 1404 adult patients were analyzed. Assessment of the images was performed in accordance with the previously published horizontal alveolar change (HAC) classification, which categorizes horizontal bone defects into four classes: HAC 1, HAC 2, HAC 3 and HAC 4 (from the least severe to the most severe condition). Analys...

Impact of teleconsultations on the conduct of oral health teams in the Telehealth Brazil Networks Programme
Abstract Telehealth has been applied in the Unified Health System (SUS) as a tool for qualifying professionals and improving the healthcare provided to the population served by the system. The aim of the present study was to evaluate the impact of teleconsultations on the qualifications of the clinical approach of the oral health teams involved in primary health care (PHC) in the state of Rio Grande do Sul under the Telehealth Brazil Networks Programme. The sample population of the study was composed of 285 dentists and 132 oral health assistants belonging to the Family Health Teams. A chi-square test was used to investiga...

Impact of history of periodontitis on gene expression of bone-related factors in young patients
Abstract Although dental implants and bone regenerative procedures are important approaches for the reestablishment of esthetics and function in young patients with a history of generalized aggressive periodontitis (GAP), no predictable outcomes have been reported, and the host osteo-immunoinflammatory response may play a relevant role in this context. In view of the lack of molecular investigations into the bone tissue condition of young patients with periodontitis, the aim of this study was to evaluate the gene expression of bone-related factors in this population. Bone biopsies were obtained from the posterior mandible ...

Effect of ScLL and 15d-PGJ2 on viability and cytokine release in LPS-stimulated fibroblasts: an in vitro study
This study evaluated the effect of a cyclopentenone-type PG, 15-Deoxy- Δ 12,14-PG J2 (15d-PGJ2), and lectin (ScLL) on the viability of human gingival fibroblasts (HGFs), and on IL-6 and TGF β -1 release by these fibroblasts, stimulated with lipopolysaccharide (LPS). HGFs were stimulated with LPS 10 μ g/ml and treated with 15d-PGJ2 1 and 2 μ g/ml, and ScLL 2 and 5 μ g/ml, for 1 and 3h, and then evaluated for viability by MTT assay. Supernatant was collected to detect IL-6 and TGF β -1 release, by ELISA. Positive control was cells kept in Dulbecco ’ s Modified Eagle ’ s Medium, and negative control was those kept i...

Erratum: Does low-cost GIC have the same survival rate as high-viscosity GIC in atraumatic restorative treatments? A RCT. Braz Oral Res. 2019;33:e125.
In this study, we used Pam2CSK4 (PAM2), a synthetic molecule that mimics bacterial lipoprotein, to investigate the effects of lipoproteins on periodontitis in mice. C57BL/6 male mice were randomly divided into three experimental groups: 1) Negative control group: animals received vehicle injection; 2) Positive control group: animals received injection of Escherichia coli lipopolysaccharide (LPS); 3) PAM2 group: animals received PAM2 injection. All the injections were performed bilaterally every other day into the palatal mucosa between first and second molars. After twenty-four days, the animals were euthanized to assess a...

Expression profile of salivary micro RNA-21 and 31 in oral potentially malignant disorders
Abstract Oral potentially malignant disorders (OPMD) possess significant chances of malignancy conversion. In order to develop an early diagnostic tool, the present study evaluated the expression of miRNA-21 and 31 as salivary markers. The case-control study was carried out in 36 healthy participants as controls and in 36 patients who were newly diagnosed as OPMD having four different lesions including leucoplakia, oral sub mucous fibrosis (OSMF) 궱 , oral lichen planus, and (OSMF) 궱 with leucoplakia. The samples were also classified as non-dysplastic, or with mild, moderate, and severe dysplasia according to their his...

Effects of restraint stress and high-fat diet on osseointegration of titanium implants: an experimental study
This study aimed to investigate the effects of chronic restraint stress (RS) and a high-fat diet (HFD) on the osseointegration of titanium implants in a rat model. After the surgical insertion of titanium implants into the metaphysis of the tibial bone, the rats were randomly divided into four equal groups (n = 8 each): control (CNT), restraint stress (RS), high-fat diet (HFD), and restraint stress plus high fat diet (RS-HFD). CNT: Rats received no further treatment during the 92-day experimental period. RS: Stress was applied to the rats beginning from two days after the implant surgery for one hour per day for the first ...
