In addition, teeth in the OT group with total pulp obliteration showed a significantly higher rate of pulp necrosis than teeth without (p < 0.001) or only partial pulp obliteration (p = 0.025). Pulp Canal Obliteration (PCO), also known as calcific metamorphosis, is a sequelae of dental trauma and usually affects the anterior teeth of young adults 5, 6. Teeth in the OT group revealed a significantly higher rate of pulp necrosis than teeth in the C group (p < 0.001). According to the degree of initial pulp obliteration, the teeth were divided into three categories: teeth without, teeth with partial, and teeth with total pulp obliteration. Pulpal condition was examined in 269 traumatized maxillary incisors after orthodontic intrusion (OT group) and in 193 traumatized maxillary incisors without subsequent orthodontic treatment (C group). Based on previous and present clinical and radiographic findings concerning pulp response to luxation injuries, it is suggested that PCO is a sequel to revascularization and/or reinnervation of a damaged pulp after injury.Limited information exists on the impact of pulp obliteration on pulpal vitality of orthodontically treated traumatized teeth. Moreover, the use of orthodontic band/resin splints significantly increased the occurrence of PCO, presumably due to the additional trauma of forceful placement and cementation of orthodontic bands in contrast to the relatively passive placement of an acid-etch/resin splint. If carefully executed, root canal treatment in teeth with an obliterated pulp canal space is highly successful and may act as a basis for internal bleaching. Limited information exists on the impact of pulp obliteration on pulpal vitality of orthodontically treated traumatized teeth. One sign of dentiogenesis imprefecta is total obliteration of the pulp chamber due to calcification of dentin. Obliteration of the pulp canal space may make root canal treatment necessary because of the development of apical periodontitis or for cosmetic reasons. Limited information exists on the impact of pulp obliteration on pulpal vitality of orthodontically treated traumatized teeth. Patient will likely know about DI or osteogenesis or know of a family issue with one of these.
Extrusion, lateral luxation and intrusion showed more frequent occurrence of PCO than did concussion and subluxation. JOE 91 In particular renal artery calcification has a high correlation to pulp stones. PCO was significantly more frequent among teeth with incomplete root formation than in teeth where root formation was completed. 1 genes associated with the obliteration of the pulp chamber phenotype by mapping known disease genes to disease phenotypes from the HPO Gene-Disease. Sensibility to electrometric pulp testing of the teeth with PCO was not significantly different from sensibility of contralateral homologues at the final examination (except for after lateral luxation, where the teeth with PCO had a significantly lower perception threshold). Pulp canal obliteration (PCO), or calcific metamorphosis, is considered by some authors as the pulp response to trauma and is characterized by the. Only 2 teeth exhibited yellow discoloration of the clinical crown and 1 showed grey discoloration. A total of 96 (15%) developed partial PCO 9 of these (1% of the total material) went on to develop total PCO. Abstract A material of 637 concussed, subluxated, extruded, laterally luxated and intruded permanent incisors was analyzed with respect to factors influencing the development of pulp canal obliteration (PCO) after injury.
