Evaluation of effect of low level laser therapy with intracanal medicament on periapical healing: A randomised control trial.

Objective(s): Photobiomodulation, also commonly referred to as low level laser therapy (LLLT), uses light energy to elicit biological responses from the cell and normalise cell function. Using LLLT on bone has been demonstrated to be effective in modulating inflammation, accelerating bone cell proliferation and enhancing the healing process. The objectives of this study were to evaluate postoperative pain and periapical healing in two different groups.

Sealing ability of three root-end filling materials prepared using an erbium: Yttrium aluminium garnet laser and endosonic tip evaluated by confocal laser scanning microscopy.

Aims: (1) To compare the sealing ability of mineral trioxide aggregate (MTA), Biodentine, and Chitra-calcium phosphate cement (CPC) when used as root-end filling, evaluated under confocal laser scanning microscope using Rhodamine B dye. (2) To evaluate effect of ultrasonic retroprep tip and an erbium:yttrium aluminium garnet (Er:YAG) laser on the integrity of three different root-end filling materials.

Materials And Methods: The root canals of 80 extracted teeth were instrumented and obturated with gutta-percha.

Management of palato radicular groove in a maxillary lateral incisor.

This study is to report the rare localization of a radicular groove on the palatal aspect of the maxillary lateral incisor and to discuss the pathology and management of the concomitant endo-periodontal defect. Unilateral palato-radicular groove was located on the Maxillary right lateral incisor of an 18-year-old female patient. The groove was associated with deep local periodontal pocket resulting in pulp necrosis and the formation of a large periapical lesion.

Sealing ability of mineral trioxide aggregate, calcium phosphate and polymethylmethacrylate bone cements on root ends prepared using an Erbium: Yttriumaluminium garnet laser and ultrasonics evaluated by confocal laser scanning microscopy.

Background: Surgical endodontic therapy comprises of exposure of the involved root apex, resection of the apical end of the root, preparation of a class I cavity, and insertion of a root end filling material. Mineral trioxide aggregate (MTA) is now the gold standard among all root end filling materials. MTA is however difficult to handle, expensive and has a very slow setting reaction.
