Abstract
Objective To assess the 6- to 24-month outcome of endodontic treatments performed, by one specialist, and to identify prognostic factors that may influence initial endodontic treatment outcome (IETO). Methods One hundred and forty-six patients out of 163 were included. A number of 201 teeth were endodontically treated, and an overall number of 408 canals were obturated. Of these, 165 teeth received initial endodontic treatment (IET). The criteria of the European Society of Endodontology were used to assess the IETO. The level of significance was set at p < 0.05%. Results Apical periodontitis (AP) was present in 42.5% of all cases, with a PAI >3 in 28.5%. The success rate (SR) was 91.5%. It was significantly higher in vital teeth (97%) than in devital teeth (87.7%) (p=0.04); however, a lower SR was recorded in teeth with AP (p=0.02). The lesion healed in 60 teeth (85.7%), decreased in size in 4 teeth (5.7%), and increased in size in 6 teeth (8.5%). A higher SR was obtained when a permanent restoration was present (94%) than absent (68.7%) (p=0.005). Conclusion Within the limitations of the study, pulp and periapical status and permanent restoration are found to be strong outcome predictors.
Highlights
Pulp and periapical diseases are most commonly due to caries and dental trauma, but dental material toxicity and iatrogenic procedures are involved [1]
Despite the extensive literature published regarding success and failure related to root canal treatments (RCTs) or endodontic treatment outcomes (ETOs) [7,8,9,10,11,12,13], a great variability exists between study protocols, prognostic factors included and data obtained
In the present retrospective study, assessment of clinical and radiographic outcomes of initial endodontic treatments was based on the Endodontic European Society guidelines [29] and Wu et al criteria [32]. e results revealed that prognostic factors significantly affecting ETO are pulp status, apical periodontitis, and coronal restoration
Summary
Pulp and periapical diseases are most commonly due to caries and dental trauma, but dental material toxicity and iatrogenic procedures are involved [1]. Boykin et al [2] reported that dental pain and infection are the most predominant reported reasons for which endodontic treatment is performed, 40 and 30%, respectively. ETs are performed either by endodontists [14,15,16,17,18,19], postgraduate students [20,21,22,23], students [1, 24, 25], or general dentists [26,27,28]. The overall success rate (OSR) of ETs is affected by these variations. It is comparable between endodontists and postgraduate students. 94% of dentists referring patients with an endodontic problem had no postgraduate qualification in endodontics [26]
