In a recent study published in The Journal of the American Dental Association, prognostic factors associated with pulp status in patients with cracked teeth (CT) who undergo treatment with occlusal veneer were analyzed. Conducted by a team of researchers, the study analyzed 80 cases of cracked teeth in 71 patients, all of whom presented with one or more crack lines (CLs) and either normal pulp vitality or reversible pulpitis. The patients underwent treatment with occlusal veneers and their demographic and clinical data were meticulously recorded. Key findings of the study include:
- Commonly Affected Teeth: Maxillary first molars were found to be the most commonly affected teeth, accounting for 38% of cases.
- Number of Crack Lines: The number of crack lines on the finish line ranged from 1 through 7, with the majority presenting with 3 crack lines (30%).
- Risk Factors for Pulp Status: Several risk factors associated with pulp status were identified through the study. These include probing depth greater than 6 mm, widening periodontal ligament of the apical area, presence of more than 4 crack lines on the finish line, and more than 2 crack lines through preparation on the finish line. These factors were significantly associated with progression to pulp disease (P < .05).
- Success Rate of Occlusal Veneer: The study reported a high success rate of 93.8% for occlusal veneer in protecting cracked teeth without the need for preventive root canal therapy.
