Treatment of invasive cervical resorption: An analysis of results using topical application of trichloracetic acid, curettage, and restoration
Objective: The purpose of this study was to carry out a clinical evaluation of the treatment of invasive cervical resorption. Method and materials: Topical application of a 90% aqueous solution of trichloracetic acid, curettage, nonsurgical root canal treatment where necessary, and restoration with glass-ionomer cement were performed on 94 patients with a total of 101 affected teeth. A minimum of 3 years' follow-up was required, unless failure occurred before that time, in which case that treatment was included. Teeth were divided into four classes, depending on the extent of the resorptive process. Class 1 represented the least invasive resorptive lesion, near the cervical area with shallow penetration into dentin, while class 4 represented the most invasive resorptive process, which had extended beyond the coronal third of the root. Results: In all class 1 and class 2 cases, the results showed complete success, judged by an absence of resorption or signs of periapical or periodontal pathosis. When overall success rate in class 3 lesions was 77.8%. Only 12.5% of teeth in class 4 were free of resorption and deemed to be clinically sound. Conclusion: The treatment regimen was successful in class 1 and class 2 cases, reasonably successful in class 3 cases, and generally unsuccessful in class 4 resorptions, where alternative treatment is recommended. Diagnosis of lesions at an early stage is, therefore, highly desirable
