Het succes van endodontische behandelingen in een gedifferentieerde endodontologiepraktijk

(2016) Scheltes, J.P.

Objectives
The aim of this study is to determine the success of endodontic treatment in a specialised en-dodontic practice and to identify factors predicting that success.
Method
In this study, the success rate of endodontically treated teeth was determined by looking at the healing and the survival of treated teeth. To achieve this, patient files were used in a retro-spective observation study. Using this method, a comparison was made between the preopera-tive status and the status at the time of recall, at least nine months after treatment. The surviv-al rate was decided by determining whether extraction took place or not. Healing was deter-mined by examining the clinical- and radiographic results. Assessment of these results were conducted using two criteria: strict- and loose-criteria.
Four factors were used for a significant predicting value on the outcome of healing: preoperative periapical radiolucency, complicating operative factors, the technical quality of the endodontic treatment, and the type of endodontic treatment. Statistical analysis was per-formed by using a logistic regression for outcomes of the several assessment criteria.
Results
Different study populations were performed by using the available information regarding rates of healing and survival. This research shows that 156 out of 157 teeth (99,4%) survived. By using the strict assessment criteria, 41 of the 131 teeth were classified as healed. Using the non-strict assessment criteria 109 of 131 teeth (83,2%) were classified as being healed.
The use of the strict criteria has shown a significant correlation between the presence or absence of a preoperative periapical radiolucency (OR: 95.55, p<0,001) and the presence or absence of complicating operative factors (OR: 5.91, p=0.029).
The use of the loose-criteria has shown a significant correlation between the presence or absence of a preoperative periapical radiolucency and the type of endodontic treatment (OR: 2.686, p=0.041).
Conclusions
Comments can be made within the limits of this study concerning the success of endodontic treatment in a specialised endodontic practice. This study shows that a preoperative periapical radiolucency in particular has a significant predicting value on the rate of healing. Further-more, complicating operative factors and the type of endodontic treatment that was used, show a significant predicting value, depending on the assessment criteria used.
Following the results of this study, additional research with multiple clinicians, work-ing at different endodontic practices is advised. Accessing the influence of specific elements of predictive values is advised. This would include the effect of the size of the preoperative periapical radiolucency and specific complicating operative factors.
