ENDODONTIC TREATMENT OF LOWER PRE-MOLAR WITH RADICULAR DILACERATION - CASE REPORT.

This study aims to present a clinical case of a second lower left premolar with marked dilaceration. The patient complained of "pain when drinking cold water" and when chewing. Clinical examination revealed extensive restoration of composite resin on the occlusal and distal surfaces. At the radiographic examination, an image of extensive and in-depth coronary restoration was perceived, suggesting proximity to the pulp chamber, besides a sharp apical dilaceration of the root. However, no periapical lesion was found. The pulp diagnosis for this case was irreversible pulpitis. The chemical-mechanical preparation was performed with the 25.05 file of the ProDesign Logic system (Easy Equipments, Belo Horizonte, MG, Brazil), followed by irrigation with 5.25% sodium hypochlorite solution. At the end of the chemical-mechanical preparation, the Easyclean file was used in a reciprocating motion at the working length (WL) for 20s. The obturation was performed using a gutta-percha FM EL cone (Odous de Deus, Belo Horizonte, MG, Brazil) using the continuous condensation wave technique. [ABSTRACT FROM AUTHOR]
