![]() Teeth with pulp canal obliteration in need of root canal treatment pose particular diagnostic and treatment challenges.Routine pulp sensibility tests are unreliable in the presence of pulp canal obliteration.Up to 75% of teeth with pulp canal obliterations are symptom-free and require no treatment other than radiographic monitoring.An interesting study of 168 traumatized, discolored, anterior teeth found that 47.6 were partially obliterated, 31.6 were totally obliterated, and 20.8 were found necrotic. Calcific metamorphosis is the partial or complete obliteration of the pulp following dental trauma. Internal staining is common following a traumatic injury to a tooth. (a.) Scarcely distinct - applied to the markings of insects. to obliterate ideas to obliterate the monuments of antiquity. t.) To wear out to remove or destroy utterly by any means to render imperceptible as. Discolouration is a common clinical finding in teeth with pulp canal obliteration It has been reported that 11.6 - 33 of boys and 3.6 - 19 of girls suffer some kind of dental trauma before age 12. t.) To erase or blot out to efface to render undecipherable, as a writing.Up to 25% of traumatized anterior teeth can develop pulp canal obliteration.This article discusses the various management approaches and highlights treatment strategies for overcoming potential complications. Root canal treatment of teeth with pulpal obliteration is often challenging. The inevitable lack of responses to normal sensibility tests and the crown discoloration add uncertainty to the management however, only approximately 7-27% of teeth with PCO will develop pulp necrosis with radiographic signs of periapical disease. These teeth provide an endodontic treatment challenge the critical management decision being whether to treat these teeth endodontically immediately upon detection of the pulpal obliteration or to wait until symptoms or signs of pulp and or periapical disease occur. Approximately 4-24% of traumatized teeth develop varying degrees of pulpal obliteration that is characterized by the apparent loss of the pulp space radiographically and a yellow discoloration of the clinical crown. ![]() Summary Pulp canal obliteration (PCO) occurs commonly following traumatic injuries to teeth. Even though radiographic assessment may give an impression. Aim To review the literature on pulp chamber and root canal obliteration in anterior teeth and to establish a clear protocol for managing teeth with fine, tortuous canal systems. Pulpal obliteration can be defined as the partial or complete calcification of the pulp chamber. Pulp canal obliteration is defined as a pulpal response to trauma that is characterized by deposition of hard tissue within the root canal space. Pulp canal obliteration: an endodontic diagnosis and treatment challenge. Rarely, pulpal side effects may occur, including altered pulpal respiration rate, internal root resorption, pulpal obliteration by secondary dentin and pulpal necrosis. Summary Pulp canal obliteration (PCO) occurs commonly following traumatic injuries to teeth.
