| description | Interoduction. Treatment of trumatized crown fractured teeth with open apex is a major problem in endodontic treatment. Long term stability of such teeth depends upon the maintainace of pulp vitality. The time period between the accident and the treatment affects the pulp vitality as well as the type of treatment and prognosis. The objective of this study was to provide a rough time table of pulpal inflammation and necrosis after the exposure of crow - fractured teeth to oral Environment. Methods. Fourty eight canine teeth in 12 young cats were used in this experiment. To make sure the teeth apecies were all open, they were checked by radiograph. The crown of all the teeth were cut 2mm from the CEJ and the pulps were left open to oral inviornment for periods of 1, 3, 7, 14, 28, 90 days. Animals were then sacrificed by vital perfusion fixation technique. Results. The mean depth of pulpal inflammation and necrosis for periods of 1, 3, 7, 14, 28 and 90 days were 1.98, 3.3, 2.39, 2.84, 3.92 and 8.57, respectively. There was no statistically significant difference between the time periods of 1, 7 and 14 days. Where as, time periods of 14 and 28 days showed significant difference. In 90 day time period, all the teeth showed total pulpal necrosis and was significantly different from all the other groups. Discussion. It appears that, trumatized open apex teeth exposed to oral Enviornment for less than 28 days could be well treated by apexogenesis. Considering the sufficient blood supply to open apex teeth in cases of deep inflammation and necrosis the teeth could be saved by partial pulpectomy. Only cases of total pulp necrosis should be treated by apexification technique. |
