Article Synopsis
- * 400 participants aged 8-15, split into overweight/obese and normal weight groups, were analyzed for various cephalometric measurements and dental stages, showing significant differences linked to BMI.
- * Results indicate that overweight/obese individuals have advanced craniofacial growth and dental age compared to normal-weight peers, suggesting the need for timely orthodontic interventions.
To investigate the anti-gingivitis efficacy of a novel oral hygiene routine consisting of a two-step stannous fluoride dentifrice and hydrogen peroxide whitening gel system, an interactive oscillating-rotating electric toothbrush, and expanded polytetrafluoroethylene floss. A total of 52 participants (n=52;mean age 35.8±11.

Methods: A 12-week, randomized controlled trial was conducted to compare the effectiveness and safety of a two-step dentifrice/gel sequence to a positive control in healthy adults with established gingivitis. After informed consent, gingivitis and stain levels were assessed by clinical examination.
Aim: The aim of this study is to assess the effect of 35% sodium ascorbate on microtensile bond strength of dentin immediately after bleaching with 35% hydrogen peroxide.
Materials And Methods: A total of 25 sound human 3 molars were collected. Teeth were randomly divided into five groups for different treatments: Group I [bleaching + immediate bonding (i.
Objective: To compare long-term microtensile bond strength of zirconia, surface-modified via a novel treatment, to current surface conditioning methods for zirconia, when resin bonded to dental composite.
Methods: Two ProCAD (porcelain) and 10 sintered ZirCAD (ZrO(2)) blocks (18 mm × 14 mm × 12 mm) were obtained from manufacturers. Twelve Herculite XRV composite blocks were fabricated (18 mm × 14 mm × 12 mm).
Purpose: To evaluate the adaptation and penetration into occlusal fissures of two different types of fissure sealants.
Methods: Extracted third molars (n=10) with evident occlusal fissures were cleaned with a pumice/water slurry and randomly divided into two groups and sealed following the manufacturers' directions as follows: Group 1--Embrace fissure sealant (Pulpdent). Surfaces were cleaned and dried, then etched for 15 seconds.
Purpose: To evaluate the effect of an 8% arginine-calcium carbonate fluoride-free desensitizing paste on the surface roughness of resin composite, porcelain, amalgam, gold, and human dental enamel both prior to and following simulated toothbrushing.
Methods: A resin composite (Filtek Supreme), a commercial porcelain (IPS Empress), an amalgam (Dispersalloy), gold (JIF-PF) and human dental enamel were used, as well as commercial finishing and polishing instruments. Eight two-sided samples were fabricated for each group.
Objective: To explore the effects of high-concentration hydrogen peroxide bleaching agents on the microleakage of composite restorations.
Methods: In 60 extracted human molars, Class V restorations were prepared with Scotchbond 1/Filtek Z250 composite. Teeth were randomly divided into four groups: (1) no bleaching; (2) bleaching with 14% hydrogen peroxide gel from Crest Whitestrips; (3) bleaching with 20% carbamide peroxide gel from Opalescence PF 20; and (4) bleaching with 38% hydrogen peroxide gel Opalescence Xtra Boost.
All biomaterials used in dentistry must be evaluated for biocompatibility using screening assays to protect patient health and safety. The purpose of this review is to explain the international biocompatibility guidelines, and to explain the structure of a test program. The test program requires the structured assessment of materials into four phases; general toxicity, local tissue irritation, pre-clinical, and clinical evaluation.
