Simulated furcation perforations were repaired with and without blood contamination utilizing tooth-colored mineral trioxide aggregrate (MTA) mixed with either MTA liquid (sterile water), lidocaine, or saline. Samples underwent Instron testing at either 24 or 72 hours and at 7 days. Data were analyzed using a 3-way ANOVA and post-hoc testing using Turkey's true test for significance. All of the...

Aim: To evaluate the accuracy of panoramic radiography in determining dentin thickness danger zone (DZ) using cone-beam computed tomography (CBCT) imaging to examine thicknesses mandibular molars at different levels. Materials and Methods: For study, 250 were selected. Dentine measured on radiography. On CBCT view, dentine mesiobuccal (MB), mesiolingual (ML), distal roots measured. The referenc...

The purpose of this study was to evaluate the ability of gray and white ProRoot MTA to seal furcation perforations in mandibular molars using a dye extraction leakage model. Sixty-four mandibular molars were randomly divided into four experimental groups. Six teeth with perforations were used as positive controls and six teeth without perforations were used as negative controls. Perforations in...

Two molars having furcation grade II involvements were selected from each of six patients with periodontal diseases. One molar received a local application of tetracycline immobilized cross-liked collagen film four times at one-week intervals (TC film-treated group) and the other received no treatment (non-treated group). The clinical and microbiological effects were, as follows, 1. Throughout ...
