BACKGROUND: Bruxism is a sleep disorder characterized by grinding and clenching of the teeth that may be related to irreversible tooth injuries. It is a prevalent condition occurring in up to 31% of adults. However, there is no definitive answer as to which of the many currently available treatments (including drug therapy, intramuscular injections, physiotherapy, biofeedback, kinesiotherapy, use of intraoral devices, or psychological therapy) is the best for the clinical management of the different manifestations of bruxism...

BACKGROUND: The objective of this study was to examine the association between low blood lead levels of <5 μg/dL and the development of dental caries among children. METHODS: The Children's Health and Environment Research (CHEER) group recruited a cohort of 7,059 school-aged children from six Korean cities. The final study populations in the permanent and deciduous teeth groups were 1,564 and 1,241 children, respectively, after excluding 4 children with blood lead levels of >5 μg/dL...

During 2011-2014, 13.3% of children and adolescents aged 6-19 years had untreated dental caries in their permanent teeth. The percentage of children and adolescents with untreated dental caries increased with age: 6.1% among those aged 6-11 years, 14.5% among those aged 12-15 years, and 22.6% among those aged 16-19 years.

The carving of a complex amalgam restoration may occasionally result in light proximal contact with the adjacent tooth. The purpose of this study was to investigate the strength of complex amalgam restorations repaired with a proximal slot amalgam preparation. Extracted human third molars of similar coronal size were sectioned 1 mm apical to the height of the contour using a saw and were randomly distributed into 9 groups of 10 teeth each. One pin was placed at each line angle of the flattened dentinal tooth surface...

Parkinson's disease (PD) is characterized by tremors and cognitive issues, and is due to the death of dopaminergic (DA-ergic) neurons in brain circuits that are responsible for producing neurotransmitter dopamine (DA). Currently, cell replacement therapies are underway to overcome existing therapeutic approaches such as drug treatments and electrical stimulation. Among the widely available sources, dental pulp stem cells from deciduous teeth (DPSC) have gained popularity due to their neural crest origin and inherent propensity toward neuronal lineage...

Periodontal disease is an inflammatory disorder affecting the supporting teeth structures, including gingiva, periodontal ligament and alveolar bone, causing loss of connective tissue, reabsorption of alveolar bone and formation of periodontal pockets. The aim of this study is to find a correlation between bacterial growth and periodontal disease. Fifty-seven patients aged between 21 and 65 years, median age 46 years, were enrolled. According to gingival pocket depth, ranging from 3 to 7 mm, patients were divided into two groups: the first (30 patients, 53%) with deep pockets ³ 5 mm and the second (27 patients, 47%) less than 5 mm...

AIM: The aim of this in vitro study was to evaluate the influence of the Dental chair light on the bond strength of light cured composite resin. MATERIALS AND METHODS: Sixty therapeutically extracted human premolar teeth were randomly allocated to two groups of 30 specimens each. In both groups light cured composite resin (Transbond XT) and MBT premolar metal brackets (3M Unitek) was used to bond brackets. In group I and II light curing was done using Light-emitting diode light curing units without and with the dental chair light respectively...

Dental stem cells can serve as a potential source of functional endothelial cells (ECs) for tissue engineering applications, but the endothelial-lineage differentiation efficiency is rather low even with growth factors and mechanical stimuli, which greatly limits their clinical applications. This is partly due to the deficiency of standard two-dimensional (2-D) culture systems, which is unable to recapitulate the three-dimensional (3-D) in vivo milieu that is rich in extracellular matrix. Hence we extracted decellularized extracellular matrix from human umbilical vein endothelial cells (HUVECs-DECM) to provide a bioactive substratum conducive to the endothelial differentiation of dental stem cells...

Dental decay affects many children, especially those from the lower socioeconomic classes. In this cross-sectional study designed to investigate the role played by sociodemographic factors, parental attitudes, and monitoring points, which are an indicator of personal perception of what controls individual health, on the prevalence of tooth decay among 5-year-old pre-school children living in a midsized city in São Paulo, Brazil. The ceo-d index of 426 children was assessed; the parents reported sociodemographic characteristics and completed two questionnaires concerning monitoring points and parental attitudes...

A randomized, double-blind, split-mouth clinical trial was performed compared the desensitizing efficacy of the resin-modified glass ionomer cement (GIC) ClinproTM XT (3M ESPE, Minnesota, USA) and the conventional GIC Vidrion R (SS White, Gloucester, UK) in a 6-month follow-up. Subjects were required to have at least two teeth with dentin hypersensitivity. Teeth were divided at random into 2 groups, one group received Clinpro XT and the other conventional GIC Vidrion R. Treatments were assessed by tactile and air blast tests using Visual Analogue Scale (VAS) at baseline, after 20 minutes, and at 7, 15, 21, 30, 90 and 180 days post-treatment...

BACKGROUND: Oral mucositis occurs in patients undergoing chemoradiation for cancer treatment. It is believed that colonization of ulcerated mucosa by bacteria, fungi and virus results in secondary infections. The effect of chlorhexidine (CHX) on the incidence and severity of oral mucositis in cancer patients was evaluated in this review. METHODS: Studies were limited to randomized placebo-controlled trials. Three databases were searched: MEDLINE (via PubMed), Web of Science and the Cochrane Library up to May 25, 2016...

A major issue in studying human neurogenetic disorders, especially rare syndromes affecting the nervous system, is the ability to grow neuronal cultures that accurately represent these disorders for analysis. Although there has been some success in generating induced pluripotent stem (iPS) cells from both skin and blood, there are still limitations to the collection and production of iPS cells from these biospecimens. We have had significant success in collecting and growing human dental pulp stem (DPS) cells from exfoliated teeth sent to our laboratory by the parents of children with a variety of rare neurogenetic syndromes...

OBJECTIVES: To update histological data on crown initiation and completion ages in southern Africans. To evaluate implications of these data for studies that: (a) rely on these data to time linear enamel hypoplasias (LEHs), or, (b) use these data for comparison to fossil hominins. MATERIALS AND METHODS: Initiation ages were calculated on 67 histological sections from southern Africans, with sample sizes ranging from one to 11 per tooth type. Crown completion ages for southern Africans were calculated in two ways...
