Treatment of intrabony periodontal defects in controlled diabetic patients with an enamel matrix derivative: a split-mouth randomized clinical trial.

Objective: This split-mouth randomized controlled trial aimed to evaluate the effect of enamel matrix derivative (EMD) associated with a simplified papilla preservation flap (SPPF) compared to SPPF alone in the surgical treatment of intrabony defects (ID) in type 2 diabetic mellitus (T2DM) patients.

Material And Methods: Thirteen patients with controlled T2DM presenting with ID in at least two quadrants were included. In each patient, the test site (TS) was treated with SPPF plus EMD, whereas the control site (CS) was treated only with SPPF.

Nano-silver Fluoride at Higher Concentration for Caries Arrest in Primary Molars: A Randomized Controlled Trial.

Aim And Objective: To compare the arresting caries effectiveness of two different silver nanoparticle (AgNP) concentrations of nano-silver fluoride (NSF), namely 400 and 600 ppm. The hypothesis is that in posterior primary teeth with occlusal and approximal active dentin carious lesions, NSF 600's effectiveness will be higher than that of the NSF 400 solution over a 6-month follow-up period.

Materials And Methods: This was a double-blind randomized clinical trial (RCT) conducted in the city of Recife, Brazil.

Evaluation of dental trauma in inmates of the most highly populated Brazilian prison complex.

Background/aim: Due to the increase in incarceration rates, the prison community has attracted much concern in the recent past. Although people in prison are often socially disadvantaged and vulnerable to a range of health problems, there is a lack of information on the oral health conditions of prisoners. Thus, the aim of this study was to survey the oral problems of a sample of the male incarcerated population of Brazil, focusing on dental trauma.

Opportunistic infections in the oral cavity can cause serious complications in immunocompromised cancer patients. Efficient treatments options are essential. This article reports two clinical cases of adolescent patients diagnosed with leukemia, who presented with infectious conditions in the oral cavity.

Association between symptoms of depression and oral health conditions.

Aims: To investigate the symptoms of depression and oral health status in Brazilian public healthcare system users.

Materials And Methods: Analysis of a cross-sectional study conducted with a sample of 776 individuals aged 15 years or older, in the urban areas of Recife (Brazil), obtained by multistage sampling. Committee on Ethics in Research with Human Beings (CAAE) 0538.

Photodynamic therapy for treatment of oral mucositis: Pilot study with pediatric patients undergoing chemotherapy.

Background: Oral mucositis has become a major dose-limiting toxicity of antineoplastic treatment.

Aim: The aim of this study was to evaluate the effect of photodynamic therapy (PDT) and low level laser therapy (LLLT) on the treatment of chemotherapy-induced mucositis in pediatric patients.

Methods: An open, controlled, and blind, randomized clinical trial was conducted with 29 patients, from 10 months to 18 years old, who were divided into two groups.

Temporomandibular disorder: otologic implications and its relationship to sleep bruxism.

Introduction: Temporomandibular disorder is an umbrella term for various clinical problems affecting the muscles of mastication, temporomandibular joint and associated structures. This disorder has a multifactor etiology, with oral parafunctional habits considered an important co-factor. Among such habits, sleep bruxism is considered a causal agent involved in the initiation and/or perpetuation of temporomandibular disorder.

State, trait, and dental anxiety in caregivers of individuals with disabilities.

Purpose: The aim of this study was to compare state anxiety, trait anxiety, and dental anxiety in caregivers of patients with special needs and caregivers of pediatric patients without special needs at dental clinics.

Materials And Methods: A quantitative, cross-sectional study was conducted. Data were collected using a semistructured questionnaire.

Temporomandibular disorders in a sample population of the Brazilian northeast.

Temporomandibular disorder (TMD) is a common condition. This study is part of a research group and it investigated the prevalence of TMD and myofascial pain and its association with gender, age and socioeconomic class. The sample comprised 100 subjects, aged 15 to 70, users of the Family Health Units' services, in the city of Recife, PE, Brazil.
