Analysis of association of TaqI VDR gene polymorphism with the chronic periodontitis in Dravidian ethnicity.

Aim: The aim of this study is to analyze the association of TaqI vitamin D receptor (VDR) gene polymorphism with the chronic periodontitis (CP) in Dravidian ethnicity.

Materials And Methods: A total of 120 subjects were recruited for this study, which included 60 CP and 60 healthy controls. TaqI VDR gene polymorphism was analyzed using specific primers and amplified by polymerase chain reaction (PCR) and visualized under 2% agarose gel.

Effect of maxillary sinus floor augmentation without bone grafts.

Objective: The objective of the present review was to determine the effectiveness of maxillary sinus floor augmentation without bone grafts using lateral window technique.

Materials And Methods: PubMed and Cochrane databases were searched for relevant articles. We also included articles by hand search until June 2012.

Estimation of pentraxin-3 levels in the gingival tissues of chronic and aggressive periodontitis participants: an in vivo study.

Background: Pentraxins are acute-phase proteins that belong to a family of evolutionarily conserved proteins, and they are considered markers of inflammation. Pentraxin-3 (PTX3) is a prototype of the long pentraxin group. It is suggested to play an important role in innate resistance against pathogens, regulation of inflammation, and clearance of apoptotic cells.

Comparative analysis of presence of Cytomegalovirus (CMV) and Epsteinbarr virus -1 (EBV-1) in cases of chronic periodontitis and aggressive periodontitis with controls.

Aim: The aim of the present study was to evaluate the presence of Cytomegalovirus (CMV) and Epsteinbarr virus -1 (EBV-1)viruses in sub gingival plaque of chronic periodontitis (groupA), aggressive periodontitis patients (group B), periodontally healthy controls (group C) and to compare the clinical parameters between virus negative and positive sites in each of these groups.

Materials And Methods: Sixty subjects were included in the study and equally divided into the 3 groups (group A - 20, group B - 20, group C - 20). Sub gingival plaque samples were obtained from the 3 deepest periodontal pocket sites in case of subjects suffering from periodontitis, and from one random bleeding site per quadrant in healthy groups.

Treatment of human periodontal infrabony defects with hydroxyapatite + β tricalcium phosphate bone graft alone and in combination with platelet rich plasma: a randomized clinical trial.

Background: The present study was aimed at comparing the clinical effectiveness of two regenerative techniques - platelet rich plasma (PRP) + bone graft (HA + β TCP) versus bone graft (HA + β TCP) + normal saline in the treatment of periodontal intrabony defects.

Materials And Methods: Ten patients diagnosed with chronic periodontitis were enrolled in a randomized split mouth clinical trial. Following phase I therapy the sites were randomly assigned to the test group - PRP + bone graft (HA + β TCP) and control group - saline + bone graft (HA + β TCP).
