IINTRODUCTION: This study’s aims were to: 1) evaluate whether or not there was a treat- ment plan change, if CBCT is used; and 2) evaluate if the use of CBCT as diagnostic tool improves the treatment outcome. We hypothesized that 1. the use of CBCT as diagnostic tool changes the treatment plan; and 2. improves the treatment outcome
MATERIALS AND METHODS: This was an IRB approved retrospective study of all the conventional re-treatments and surgical RCT performed at Boston University Post-doctoral clinic from 2009 - 2015. Of 10,836 cases completed, 674 cases had a CBCT on file and 31 had a pre- and post-CBCT treatment plan with at least 3 months follow up. Cases with CBCT were matched (2 to 1) with cases without CBCT based on patients’ sex, age, tooth type, diagnosis, procedure performed, and insurance type. Chart notes and treatments were reviewed to identifytreatment plan changes. The investigator evaluated outcome as either Success/Survive/ Failure. Statistical Analyses tested for differences in treatment plan and Success/Survive/ Failure rates at minimum 3 months.
RESULT: 31 cases and 49 controls were evaluated. There were no differences in mean age (46) or insurance between cases and controls. In over half of the cases (54.8%) the treatment plan changed when CBCT was used. Cases with CBCT had 32% success rate, 60% sur- vival rate and 8% failure rate at minimum 3 months whereas cases without CBCT had 22.4% success rate, 53.1% survival rate and 24.5% failure rate, p-value = 0.21.
CONCLUSION: The use of CBCT as diagnostic tool affected more than half of the treatment plans. While CBCT appeared to improve the treatment outcomes, the difference in this small sample is not statistically significant. Future research will require larger sample sizes to test whether CBCT improves treatment efficacy in endodontics.
