Objective: The aim of this prospective, clinical study was to follow-up root canal treatments performed by dentists in the practice-based endodontic research network setting, to assess treatment outcome and factors related to treatment outcome.
Material and methods: Baseline information from 536 teeth was included, follow-up information on 269 teeth (50%) was available. Treatments were performed by 12 dentists during 2017–2018. Follow-up period varied from 3.5 months to 3 years. Treatment outcome was assessed in periapical radiographs using the Periapical Index (PAI). Cases were classified as referred or not. Pre-, intra-, and post-operative variables were recorded by the dentists during treatment and analysed at follow-up in relation to treatment outcome.
Results: Periapical status improved or remained healthy in 174 (66%) teeth. If PAI at baseline was 3, 4, or 5, the outcome was affected negatively (p = 0.049). The length and seal of the root filling was assessed adequate in 75% and 63% of the teeth, respectively. Adequate seal (p = 0.02) and length (p = 0.03) resulted in improved treatment outcome.
Conclusions: When initial periapical status and/or quality of the root filling was good, there was a higher chance of a successful treatment outcome.
