Distribution of Dendritic Cells and Langerhans Cells in Peri-implant Mucosa.

Background: Peri-implant diseases leading to the failure of dental implants is concern in the field of dentistry. Difference in immune response around peri-implant tissues with healthy tissue might be responsible for the hidden cause of peri-implant diseases. Hence, in the current study, the dispersion of the dendritic cell (DC) subpopulations and Langerhans cells (LCs) was evaluated in healthy peri-implant mucosa (HPIM) and healthy mucosa (HM) to know the imbalance in immune homeostasis.

Estimation of phagocytic activity of polymorphonuclear leukocytes in chronic and aggressive periodontitis patients with nitroblue tetrazolium test.

Context: The phagocytic activity of polymorphonuclear leukocytes (PMN) is influenced by the type of disease entity, i.e., chronic generalized periodontitis, generalized aggressive periodontitis, and chronic generalized gingivitis.

Oral hygiene and periodontal status of teenagers with special needs in the district of Nalgonda, India.

Objectives: To assess oral hygiene status, oral hygiene practices and periodontal status among 14-17-year-old visually impaired, deaf and dumb, intellectually disabled and physically challenged and normal teenagers in the district of Nalgonda, South India.

Materials And Methods: Seven hundred and fifty teenagers in the age group of 14-17 years, constituting visually impaired, deaf and dumb, intellectually disabled, physically challenged and normal teenagers, were studied. Oral hygiene status and periodontal status were assessed using clinical indices and compared.

Multi-centre, randomized clinical trial on the efficacy and safety of recombinant human platelet-derived growth factor with β-tricalcium phosphate in human intra-osseous periodontal defects.

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, active-controlled, randomized, multi-centre clinical trial, 54 patients with periodontal osseous defects were randomly assigned to rhPDGF-BB+β-TCP or β-TCP. Following periodontal surgery, respective implantation was performed.
