OBJECTIVES: The objective of this randomized controlled trial was to assess the influence of use of posts as well as the type of posterior tooth (premolars vs molars) for the treatment with lithium disilicate (LS2) partial crowns. MATERIALS AND METHODS: A total of 60 patients were treated with posterior LS2 partial crowns. Two groups (n = 60) were made based on the type of restored tooth: Group 1, premolars and Group 2, molars. The samples of each group were divided into 2 subgroups (n = 30): Subgroup A restored with fiber posts and Subgroup B without them...

OBJECTIVE: This study aimed to evaluate the epidemiological and reporting characteristics of systematic reviews (SRs) in dentistry indexed within PubMed during the year 2017. METHODS: We searched for SRs in dentistry indexed within PubMed in 2017. Study selection was undertaken by two reviewers independently. Data related to epidemiological and reporting characteristics were extracted by one of three reviewers. A descriptive analysis of the data was performed. Characteristics of SRs were analyzed considering all SRs included and subgrouped by dental specialties...

OBJECTIVES: Sleep bruxism (SB), characterized by repetitive jaw-muscle activity during sleep, is often suggested as a cause of temporomandibular disorders (TMD), orofacial pain, and headache. This study aimed to challenge the relationship between jaw-muscle electromyographic (EMG) activity during sleep and jaw muscle symptoms including pain by modulation of the levels of EMG activity. Contingent electrical stimulation (CES) using a portable single-channel EMG device was applied at different stimulus intensities to inhibit jaw muscle activity...

OBJECTIVES: Osteoclast differentiation is regulated by transcriptional, post-transcriptional and post-translational mechanisms. Micro-ribonucleic acids (miRNAs) are 20-24 nucleotides long non-coding RNAs involved in post-translational regulation of gene expressions during osteoclast differentiation. The objective of the present study was to investigate the role played by the miRNA, miR-338-3p, in osteoclastogenesis. METHODS: Osteoclastogenesis was induced in murine RAW264...

OBJECTIVES: To compare the effect of conventional complete dentures fabricated using two different impression methods on masticatory performance and factors relating to masticatory performance in a randomized controlled trial. METHODS: A crossover randomized controlled trial was performed with edentulous patients requiring maxillomandibular complete dentures. Mandibular complete dentures were fabricated using two different methods. The conventional method (C) used a custom tray border molded with an impression compound and a silicone...

OBJECTIVES: Although stress is prevalent amongst dentists, there is a paucity of data on the impact of stressors on dentists' clinical performance. To address this gap in the literature, the aim of the present study was to explore the role of time pressure, representing one common stressor, on dentists' radiographic diagnostic performance. METHODS: Forty dentists were randomised to examine and provide a radiographic report on two sets of radiographs (six bitewings in each set) under two conditions on a cross-over basis: time-pressure vs...

OBJECTIVE: To assess the relationship between Intimate partner violence (IPV) (a highly prevalent form of domestic abuse) with the subsequent development of Temporomandibular joint disorder (TMD). METHODS: A retrospective open cohort study using a UK primary care database was undertaken. 18,547 women exposed to IPV were matched by age to 74,188 unexposed women. Defined through clinical codes the outcome of interest was TMD, and adjusted incidence rates (aIRR) were used to describe the relationship after considering covariates of interest...

OBJECTIVES: To assess the efficacy of 8% arginine containing prophylaxis products over 24 weeks in subjects with dentin hypersensitivity (DH). METHODS: 297 patients with established DH (Schiff score 2, 3) in three European study centers were randomly assigned to either 8% arginine and calcium carbonate in-office prophylaxis paste and the respective toothpaste (test group) or fluoride-free prophylaxis paste and sodium monoflourophosphate toothpaste as a negative control group...

OBJECTIVES: To explore the experience among patients with multiple dental loss as a consequence of treatment for head and neck cancer METHODS: Semi-structured qualitative interviews were conducted with a purposive sample of fifteen people with head and neck cancer, who had multiple teeth removed as part of their tumour resection or extracted pre-radiotherapy. The interviews were digitally recorded and transcribed for analysis by two researchers, independently. RESULTS: The interview data were categorized into four themes: 1...

OBJECTIVES: This study aimed to evaluate whether coating tooth surfaces with sodium fluoride (NaF) or silver diamine fluoride (SDF) inhibits bacteria-induced pH reductions at the bacteria/tooth interface. METHODS: Specimens of coronal enamel (CE) or root dentin (RD) were prepared. The surfaces of the specimens were treated with 2% NaF or 38% SDF solution. Some specimens were aged for 1 week after being treated. A tooth specimen was fixed to the bottom of the well of the experimental apparatus...
