A comparative evaluation of the effectiveness of guided tissue regeneration by using a collagen membrane with or without decalcified freeze-dried bone allograft in the treatment of infrabony defects: A clinical and radiographic study.

Background: The present, randomized, controlled clinical and radiographic study was undertaken to compare the effectiveness of guided tissue regeneration (GTR) by using a collagen membrane barrier with or without decalcified freeze-dried bone allograft (DFDBA) in the treatment of periodontal infrabony defects characterized by unfavorable architecture.

Materials And Methods: Sixteen systemically healthy patients with 20 periodontal infrabony defects were selected for the study. Each patient had at least ≥ 5 mm clinical probing pocket depth (PPD) at the selected site and depth of intrabony component ≥ 3 mm as assessed by clinical and radiographic measurements.

Focal fibrous overgrowths: a case series and review of literature.

Intraoral fibrous overgrowths of the soft tissues are relatively common and may be benign reactive or neoplastic lesions. A series of 10 lesions is presented which included pyogenic granuloma, fibroma and peripheral ossifying fibroma. Almost all the lesions occurred in the second and third decades and were present in the anterior segment of the jaws, with a distinct female predilection.
