AIM the objective of the study was to evaluate the safety and efficacy of a formulation containing recombinant human platelet-derived growth factor (rhPDGF-BB) and β-tricalcium phosphate (β-TCP) in patients with periodontal defects and to compare it with those of β-TCP alone. MATERIALS AND METHODS in this double-blind, prospective, parallel,(More)
One of the most common esthetic concerns associated with the periodontal tissues is gingival recession. Gingival recession is the exposure of root surfaces due to apical migration of the gingival tissue margins; gingival margin migrates apical to the cementoenamel junction. Although it rarely results in tooth loss, marginal tissue recession is associated(More)
BACKGROUND There are limited clinical experiments addressing the effects of photodynamic therapy (PDT) and low-level laser therapy (LLLT) as an adjunct to conventional scaling and root planing (SRP) alone. AIM The aim of this clinical trial was to evaluate the clinical effects of adjunctive use of PDT, combination of PDT with LLLT as adjunct to(More)
INTRODUCTION Good oral health is important for an individual as well as social well-being. Occupational stress and work exhaustion in Information Technology (IT) professionals may influence the oral health and oral health related quality of life. AIM To assess and compare self-reported obstacles for regular dental care and dental visits among IT(More)
A variety of aldehydes undergo smooth coupling with 4-hydroxy-N-methyl-2-methylene-N-phenylbutanamide in the presence of BF3·OEt2 under ambient conditions to produce the corresponding spiro-oxindole derivatives in good yields with excellent selectivity. It is an entirely new strategy to construct the spirocycles in a one-pot operation through a Prins(More)
The extraction and spectrophotometric determination of vanadium (V) with oxine is investigated at higher acidities than described previously. Under these conditions, n-butanol and other alcohols are found to exert a synergic effect on the extraction of vanadium into benzene. In the presence of alcohol only a 6-fold ligand excess is needed for quantitative(More)
Glycemic index of grain amaranth, wheat and rice preparations was studied in non-insulin dependent diabetic subjects. Diets containing 50 g carbohydrate equivalent were given and post-prandial blood glucose estimated at different intervals. Glycemic index calculated for different experimental diets showed that GI of amaranth-wheat composite flour diet(More)
Lanthanide ions are found to form colourless mixed-ligand complexes with antipyrine in presence of perchlorate at pH 4.0, and these are quantitatively extractable into nitrobenzene. The composition of the extracted species is shown to be metal:antipyrine:perchlorate = 1:6:3. The variation of the extraction constants with atomic number of the lanthanides is(More)
