Canines erupted through grafted alveolar cleft defects in patients with alveolar clefts: a pulp testing evaluation study.
An electric pulp tester (EPT) was used to evaluate the pulpal response of erupted canines in 75 patients: 16 patients with unilateral cleft palate who received autogenous bone grafts to correct their alveolar cleft defects before canine eruption; 35 patients without cleft palate whose canines erupted spontaneously, but who required orthodontic treatment for alignment; and 24 patients without clefts whose canines required surgical uncovering and orthodontic assistance for eruption. Thirty-one percent of the erupted canines in the patients with grafted unilateral clefts did not respond to EPT, whereas all canines in the contralateral noncleft side responded to EPT. There was no clinical or radiographic evidence of pulpal pathosis of the canines that had erupted through the grafted alveolar clefts. However, these teeth had a high incidence of nonresponsiveness to pulp stimulation, therefore necessitating close follow-up in case they show eventual signs of pulpal degeneration that may require endodontic intervention.
