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. The analysis included both human and animal studies which satisfied the following criteria: Minimum of 6 months follow-up, no use of bone grafts, and lateral window approach to the sinus. RESULTS: We included 22 articles in the review. A descriptive analysis of the constructed evidence tables indicated that there is evidence of predictable a mount of bone formation in the maxillary sinus augmentation without the use of bone grafts. CONCLUSION: Within the limits of the articles and data available, maxillary sinus augmentation without bone graft might be considered effective inpredictable bone formation.

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. RESULTS: Our study results showed that Tt and tt genotype had a higher frequency of occurrence in CP compared with controls. Similarly, t allele was found to be associated with CP. CONCLUSION: Our study concludes that TaqI VDR gene polymorphism is associated with CP in Dravidian ethnicity.

Treatment of human periodontal infrabony defects with hydroxyapatite + ß 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 + ß TCP) versus bone graft (HA + ß 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 + ß TCP) and control group - saline + bone graft (HA + ß TCP). Clinical parameters recorded at baseline and 6 months included plaque index, probing pocket depth, relative attachment levels, and relative gingival margin levels. Hard tissue evaluation was done using digital radiography to evaluate the image intensity and therefore the radioopacity of a desired region of interest in the intrabony defect. Pre- and postoperative comparisons were made between the treatment groups at 6 months. RESULTS: Test group sites showed a significantly higher reduction in pocket depth compared to control group sites. Test group sites showed a significantly higher amount of radioopacity in the regions of interest, indicative of better graft remodeling, compared to control group sites. CONCLUSION: (HA + ß TCP) bone graft appears to be a beneficial material in the treatment of human periodontal intrabony defects. When combined with platelet-rich plasma there is a significantly higher reduction in probing pocket depth, higher gain in attachment levels and higher amount of radio-density seen in the intrabony defects.

Systemic lupus erythematosus.

Desquamative gingival lesions are non-plaque induced inflammatory gingival lesions. It is a clinical description and not a diagnosis. These desquamative lesions represent oral manifestations of various dermatoses. Systemic lupus erythematous (SLE), one of the rare dermatoses shows desquamative lesions as the oral manifestation. We here with report a case of SLE with oral lesions involving gingiva of a 36 year old female patient. The clinical presentation, histological features, and investigatory findings are discussed.
