Analysis of the Clark technique in endodontic procedures

Abstract

Introduction: the Clark radiographic technique constitutes an essential diagnostic resource in endodontics, as it enables the localization of additional canals and dental structures with greater clinical precision.

Objective: to evaluate the level of knowledge and perception regarding the Clark technique among dental professionals and students in Ambato.

Methods: an observational, descriptive, cross-sectional study conducted in 2024. The population included 63 professionals and 90 students, with a sample of 50 participants selected by convenience. A five-question survey, previously validated, was applied to obtain information that addressed the studied variables. Descriptive statistical methods were employed for data analysis, while medical ethics were respected.

Results: among professionals, 78 % were familiar with the technique and 67 % had used it, considering it effective in clinical practice. Twenty-two percent reported minimal difficulties in its application. Likewise, 67 % acknowledged its usefulness in other dental treatments. Among students, 66 % were aware of the existence of radiographic techniques for proximal surfaces, but only 32 % recognized its capacity to identify additional canals. Eighty-eight percent expressed willingness to use it in their future practice, and 51 % recognized its usefulness in molars with multiple canals.

Conclusions: solid knowledge and frequent application of the Clark technique were observed among professionals. Students showed theoretical gaps but a high willingness to learn it. The need to strengthen academic and practical training in endodontic radiodiagnosis is highlighted, consolidating the technique as a key tool to improve diagnostic precision and the quality of dental treatment.
