Cementum, apical morphology and hypercementosis: a probable adaptive response of the periodontal support tissues and potential orthodontic implications
(Dental Press International, 2012-02-01)
Information about orthodontic movement of teeth with hypercementosis is scarce. As cementum deposition continues to occur, cementum is expected to change the shape of the root and apex over time, but this has not yet been ...
Calcium hydroxide root canal dressing. Histopathological evaluation of periapical repair at different time periods.
(2002-03-01)
The objective of this study was to evaluate periapical and apical repair using calcium hydroxide root canal dressings for different lengths of times in teeth with induced chronic periapical lesions. A total of 61 root ...
EM evaluation of bacterial biofilm and microorganisms on the apical external root surface of human teeth
(2002-12-01)
The aim of this study was to evaluate the presence of bacterial biofilm on the external surface of the root apex in teeth with pulp necrosis, with and without radiographically visible periapical lesions, and in teeth with ...
Apoptosis in the early developing periodontium of rat molars
(2000-02-01)
Development of the periodontium involves a series of complex steps that result in the formation of root dentine, cementum, bone and fibres of the ligament. These precisely controlled and timed events require the participation ...
Reaction of dogs' teeth to root canal filling with mineral trioxide aggregate or a glass ionomer sealer
(1999-11-01)
This study was conducted to observe the reaction of apical tissues of dogs' teeth after root canal filling with gutta-percha and mineral trioxide aggregate (MTA) or a glass ionomer (Ketac-Endo) as a sealer. The root canals ...
Influence of dental exposure to oral environment on smear layer removal and collagen exhibition after using different conditioning agents
(2011-12-28)
Although in vitro studies have shown encouraging results for root surface conditioning with demineralizing agents, in vivo studies have failed to show its benefits in periodontal healing. This can be attributed to several ...
Mineral trioxide aggregate repair of lateral root perforations
(2001-12-01)
This study was conducted to observe the healing process of intentional lateral root perforation repaired with mineral trioxide aggregate (MTA). Forty-eight root canals of dogs' teeth were instrumented and filled. After ...
Smear layer removal and collagen fiber exposure using tetracycline hydrochloride conditioning
(2008-07-01)
Aim: Smear layer removal and collagen fiber exposure may improve periodontal treatment and regeneration. This in vitro study assessed smear layer removal and collagen fiber exposure after tetracycline hydrochloride (TTC) ...
