- Foraminal enlargement: comparative study of master apical file in upper front teethPublication . Lopo, Lúcia Reis Baptista; Guimarães, DuarteIntroduction: Foramen Enlargement has been the subject of growing interest in clinical endodontic practice due to its potential to enhance apical disinfection and improve the long-term success of root canal treatment. In maxillary anterior teeth, effective apical control is crucial to prevent post-treatment complications and ensure the long-term efficacy of the treatment. The process of apical calibration, particularly the selection of the Master Apical File of ISO size 0.25 or larger, influences the efficacy of root canal treatment by promoting better adaptation and apical cleaning. However, the impact of correctly determining the Master Apical File on the success of root canal treatment, specifically in maxillary anterior teeth, remains poorly understood. This study aims to provide clinical information on the role of correctly determining apical gauging, focusing on the optimal selection of the Master Apical File. To determine whether the choice of the Master Apical File in non-surgical endodontic treatment of maxillary anterior teeth performed over the last 5 years, at the FCS-UFP Dental Teaching Clinic and other private clinics in the Porto metropolitan area and the Algarve, selected on the basis of an ISO size ≥ 025, directly affects the efficacy and long-term success of their endodontic treatment. This comparative analysis sought to clarify the clinical benefits and limitations of determining the master apical file, with the ultimate aim of guiding evidence-based decisions regarding the selection of apical files. This comparative, observational study includes 154 cases of root canal treatment performed on maxillary teeth. Data collection focused on the size of the Master Apical file used, Apical Gauge, tooth treated, initial diagnosis, radiographic assessment and available clinical follow-up results. Statistical analysis was used to assess the relationship between the anterior maxillary teeth and the choice of the master apical file. Confidentiality and patient anonymity were ensured through the use of an alphanumeric code for each case. Conservative calibration prevailed (ISO ≤ 025: 56.5%), but 43.5% of cases the master apical filed used was ISO > 025. Significant associations identified: periapical lesions (OR= 7.46; p=0.002), endodontic retreatment (20.9% vs 10.3%; p 025, corresponding to 64.1% of cases in this group. On the other hand, the upper lateral incisors (12 and 22) had a higher proportion of ISO calibres ≤ 025 (64.8%). 53.8% of the canines had an apical gauge reading greater than 0.25. Significant associations reinforce individualised apical calibration using an apical gauge as an essential approach, bridging the gap between international guidelines and national clinical practice.
