Summary

The dental pulp is a vital tissue that can be prone to physiological or pathological changes. Denticles, pulp stones, or other calcifications are frequently observed within "healthy" pulps. However, these tissue alterations can complicate the endodontic treatment. According to the American Association of Endodontists, teeth exhibiting "pulpal obliteration" fall into the moderate to high difficulty category of treatments, and their failure rate ranges from 10 to 19 per cent 1,2. In fact, pulpal calcification alone is not a reason for endodontic treatment. Root canal treatment is recommended and deemed necessary only in the presence of peri-radicular pathology or if the affected tooth shows symptoms. Today's techniques and materials offer higher standards, resulting in better root canal treatments and allowing proper handling of procedural errors. One of these materials is Cone beam computed tomography (CBCT) which is more reliable in detecting periapical lesions compared with digital periapical radiographs 3,visual aids, and ultrasonics 1. However, when performed by a non-experienced dentist, the risk of perforations, missed canals, stripping, and ledges arises 2. For the treatment of these challenging instances, the development of guided endodontics with a trephination guide, a metal sleeve, and an appropriate drill might be of interest 4. With several in vitro studies 5-7 and case reports 8,9 being published each year, this approach is becoming more prevalent in the literature. Additionally, a new endodontic guide software is being used to build new shapes for guides, sleeves, and drills, which will make it easier to attain correct access using the guiding technique. However, there is no information regarding the detection and negotiation of root canals, the dental substance loss, the treatment duration using the guided technique compared to the conventional technique for root canal treatments (RCTs) in clinical practice 10. This study is conducted to compare the conventional endodontic treatment to the guided approach in lower incisors with calcified root canals by focusing on the following aspects: the detection and negotiation of canals, the amount of substance loss, and the treatment duration.

  • Dentinal Loss

Interventions

PROCEDURE

conventional endodontic treatment

The conventional access cavity was prepared under the microscope through the incisal edge as this approach facilitates straight-line access. A high-speed contra-angle handpiece, associated with a long surgical bur 010 (Meisinger, CO, USA), was used until the dentin was exposed, which is in general 3 to 4 millimeters from the incisal edge. Then, the ultrasonic tip ED5 (woodpecker-DTE, Guilin, China) was marked with a stopper according to the calcification level viewed on the preoperative CBCT and then used gently at the stopper level until the canal was found.

PROCEDURE

Guided endodontic treatment

In all cases, digital and clinical protocols were followed according to the method reported by Zehnder et al. and Connert et al. The guide was replaced, and the access cavity precisely drilled using the EG6 drill, mounted on a low-speed contra-angle handpiece. With every 3 mm of progression, the cavity was rinsed, and the head of the bur was cleaned until reaching the canal. The irrigation was done to avoid overheating the dentine and the accumulation of dentine debris
