OBJECTIVE To investigate the effect of three manual toothbrushes on dental plaque and gingival inflammation. METHODS The elmex Sensitive Extra Soft (ESES), elmex Sensitive Soft (ESS) and an ADA standard toothbrush (ADAS) were evaluated in a randomized clinical trial. Subjects brushed twice daily in their usual manner. Plaque index (PI), gingival index(More)
PURPOSE We conducted a synthetic quantitative review of the published clinical trials on the effectiveness of antibiotic prophylaxis in third molar surgery. MATERIALS AND METHODS Electronic databases were searched for randomized controlled trials. The primary outcome variables included alveolar osteitis (AO) and surgical wound infection. The extracted(More)
The aim of this study was to review the cytokine profiles in the synovial fluid (SF) of patients with temporomandibular joint disorders (TMJD). Databases were searched from 1965 till September 2015 using different combinations of the following key words: "Temporomandibular joint"; "Cytokine"; "disorder"; and "synovial fluid" and "inflammation". Titles and(More)
OBJECTIVE To study the effects of 6% H2O2 activated with LED light on surface enamel as compared to orange juice challenges in vitro. METHODS A total of 40 human enamel discs were incubated in saliva overnight to allow pellicle formation and then divided into three groups: 15 for whitening treatments, 15 for orange juice immersions and 10 for normal(More)
OBJECTIVES This study assesses the application of the focus variation 3D microscopy for the evaluation of dental erosion and fluoride treatment for prevention of enamel erosion in vitro. METHODS Human dental enamel disks were treated with Prevident 5000 (PV, n=15) for 1 week and compared with a reference group (PN, n=15) after orange juice erosion in(More)
To assess the effects of smokeless tobacco on the secretory immune system and dental caries, we examined users of smokeless tobacco and non-tobacco users. There were no significant differences in the prevalence of DMFS between users and non-users. There was significantly more salivary IgA, IgA2 and J-chain in users. Levels of salivary lysozyme and(More)
OBJECTIVE To evaluate the effectiveness of a dentifrice with 5000ppm fluoride in preventing dental erosion by orange juice in situ in comparison to a control dentifrice with 1450ppm fluoride. METHODS This was a double-blind and randomized clinical study with a cross-over design. Sixteen subjects wore an intra-oral appliance containing two enamel disks(More)
OBJECTIVE The aim was to compare the periodontal inflammatory conditions among habitual gutka chewers and betel quid (BQ) chewers. MATERIAL AND METHODS Forty-five gutka chewers, 45 BQ chewers and 50 non-chewers (controls) were included. Demographic data regarding age, gender, duration, and frequency of gutka- and BQ-chewing habits and gingival bleeding(More)
The levels of parotid salivary IgA and serum IgG antibodies from dental caries-resistant (CR) and caries-susceptible (CS) individuals to Streptococcus mutans antigens were determined. In general, the levels of salivary IgA and serum IgG antibodies to S. mutans antigens were significantly higher in CR subjects than in CS individuals. There were significantly(More)
OBJECTIVES To study the color stability of dental composite resins using a thermocycling stain challenge model accounting for the complex effects of oral environment and tooth brushing. METHODS Composite resin discs were made from Filtek Supreme Ultra (FiltekSU), TPH3 and Renamel, and subjected to thermocycling challenges in warm coffee (55 °C/pH 5.2) and(More)
