PR83 - Incidence of Pulpal Complications Following Diagnosis of Cracked Teeth With Vital Pulps

Thursday, April 26
10:00 AM - 1:00 PM
Room: Exhibit Hall

This retrospective cohort study aimed to gather data on the incidence of pulpal complications in cracked teeth. One hundred and eighty-four patients with 199 cracked teeth diagnosed with reversible pulpitis were included. They were treated from January 2010 to December 2013 at the National Dental Centre, Singapore. These teeth were identified by inspection, transillumination and positive bite test. A diagnosis of reversible pulpitis was taken if the tooth had no history of spontaneous pain; positive but no lingering pain to cold test and an absence of signs of periapical pathosis. After diagnosis, orthodontic bands were cemented and the teeth were referred for crown restoration. Patients were recalled more than three years later except for those patients whose teeth had undergone endodontic treatment or were extracted. The results showed that 58 out of 199 teeth (29%) had pulpal complications. 38/58 (66%) were diagnosed with irreversible pulpitis after 14 months (median 437 days) and 20/58 (34%) had necrotic pulps after 25 months (median 755 days). Prognostic factors that could influence the incidence of pulpal complications were analyzed by multiple logistic regression. In conclusion, 71% (141/199) of cracked teeth with reversible pulpitis remained vital after three years. It seems essential to brace the cracked tooth, minimize cusp flexion and provide full coverage of the cracks. When treated early, the majority of the pulps in these teeth still have a chance to survive.
