Comparative Assessment of Qmix as Endodontic Irrigant on Reversal of Bond Strength in Teeth Subjected to Irradiation: An Scanning Electron Microscope Study.

Aim: The aim of this current study was to compare and evaluate the reversal efficacy of Qmix and chitosan-based irrigation materials quantitatively through the assessment of the push-out bond strength of bioceramic sealer employing universal testing machine and to qualitatively analyze the sealer/dentin interface by scanning electron microscope (SEM) in the teeth subjected to fractioned radiation.

Materials And Methods: Ninety single-rooted straight human maxillary central incisors were randomly divided into six groups ( = 15) where in three groups comprise Chitosan, Qmix, and EDTA/sodium hypochlorite which were not exposed to irradiation while other three groups were challenged with irradiation protocols. Root canals were prepared with ProTaper universal system and all the samples were irrigated according to the final irrigation protocols and obturated with bioceramic sealers.

Assessment of Clinical and Radiographic Success Rate of Formocresol-based Pulpotomy versus Collagen-based Pulpotomy: An Study.

Aim: The aim of the study is (a) To use collagen as a pulpotomy material in comparison with the gold standard formocresol-based pulpotomy, (b) to assess the clinical and radiographic success rate of formocresol pulpotomy and collagen-based pulpotomy, and (c) to compare the success rate of formocresol-based pulpotomy and collagen-based pulpotomy over a definitive interval of time.

Materials And Methods: Totally 30 primary first or second molars indicated for pulpotomy after confirming with the operative diagnosis were taken as samples for this study. This split-mouth technique consists of two groups: Group 1-formocresol pulpotomy ( = 15), and group 2-collagen-based pulpotomy ( = 15).

Estimation of TNF-α Levels in Saliva and Serum of Patients with Periodontal Health and Chronic Periodontitis: A Case-control Study.

Aim: The aim of this case-control study is to estimate the circulatory levels of tumor necrosis factor alpha (TNF-α) in saliva and serum of patients with chronic periodontitis and periodontally healthy subjects.

Materials And Methods: Forty-four patients were screened, and based on biofilm-gingival interface (BGI) index, they were grouped into group I healthy periodontium [BGI-H (20)] and group II periodontitis [BGI-P3 (24)]. Venous blood and salivary samples were collected and analyzed using solid-phase enzyme-linked immunosorbent assay.
