Objective: To present a new, simple and economical appliance for bringing a palatally impacted canine into the oral cavity. Material and methods- The basic appliance design incorporatesAdams clasps, usually on both first molars, a posterior bite block and bow of 0.8 mm wire with a stainless steel tubing (to increase the strength) with a helix at the open end, to wear an elastic from attachment on the tooth. Results: Treatment resulted in the eruption of left canine till the occlusal level in the oral cavity through the attached mucosa and simultaneous correction of rotated right canine, with coinciding midlines and no mandibular shift. Conclusion: The simple upper removable appliance can be used as an excellent method of treating palatally impacted canines.Keywords

The main indication for ischolar_main coverage procedures is esthetic or cosmetic demand by the patient. Root coverage procedures mainly include use of pedicle soft tissue grafts or free autogenous grafts. Recently acellular dermal matrix allograft has been introduced as a substitute for donor tissue in gingival augmentation procedures.Keywords

This study was conducted to evaluate stress pattern distribution in the periodontal ligament during various orthodontic tooth movements. Methods:A 3 dimensional FEM model of upper central incisor was developed from C.T scan images of the skull excluding the mandible. The principal stress obtained on the periodontal ligament due to various orthodontic loadings (tipping, bodily movement, intrusion, extrusion and rotations) were tested. Results: Intrusion, extrusion and rotation produced stresses concentrated at apex of ischolar_main. Bodily movement and tipping forces produce stress concentrated at the alveolar crest and not at the ischolar_main apex. Conclusion:Clinical implications of this study suggests that if the clinician is concerned about placing heavy stresses on the ischolar_main apex then vertical and rotational forces must be applied with caution.Keywords

The human inflammatory periodontal diseases are amongst the most common of chronic diseases. The predominant inflammatory cell (96%) within the healthy connective tissue and epithelium of the gingiva is polymorphonuclear leucocyte (PMNL). Periodontopathic bacteria in the gingivomucosal tissue may functionally activate PMNLs leading to an increased production of reactive oxygen species (ROS). Chronic inflammation subjects the nearby cells to elevated levels of free radicals (ROS) due to extracellular release from phagocytic cells. Antioxidants block the process of oxidation by neutralizing free radicals. In doing so, the antioxidant themselves become oxidized. Because of this, there is a constant need to replenish our antioxidant resources.Keywords
