Brief summary
The aim of this observational study is to compare the treatment durations of different stages of routine root canal therapy performed on maxillary molar teeth using direct vision, magnification loupes, and a dental operating microscope. The primary question the study seeks to answer is whether there is a significant difference in the duration of endodontic procedures performed under different magnification techniques. Patients indicated for root canal treatment in their maxillary first molar teeth will receive standard root canal therapy in accordance with routine clinical protocols. The duration of each procedural step will be recorded and subsequently compared among the three magnification methods.
Detailed description
In this observational study, routine root canal treatment procedures will be performed in accordance with standard endodontic protocols on patients who applied to the Department of Endodontics, Faculty of Dentistry, Uşak University, and were indicated for root canal treatment on their maxillary first molar teeth. 1. The treatment procedures consist of seven main stages: 2. Preparation of the access cavity 3. Determination of the working length 4. Shaping of the root canals 5. Detection and shaping of the MB2 canal 6. Final irrigation and passive ultrasonic activation 7. Root canal filling Application of the coronal restoration All steps will be carried out according to standard clinical endodontic protocols under rubber dam isolation. The duration of each stage will be recorded individually. Participants will be divided into three groups based on the magnification technique used during treatment: Group 1: Treatments performed under direct vision Group 2: Treatments performed using dental loupes Group 3: Treatments performed using a dental operating microscope All procedures in each group will follow the same standardized root canal treatment protocol, differing only in the magnification technique employed.

Inclusion criteria
* Patients requiring root canal treatment of the maxillary first molar tooth
Exclusion criteria
* Previous root canal treatment on the maxillary first molar tooth * Presence of fracture or crack in the maxillary first molar tooth * Lack of indication for completing treatment in a single session * Patient refusal to continue treatment during the procedure * Indication for extraction due to complications during treatment * Teeth indicated for fiber post restoration due to excessive material loss
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Duration of Each Procedural Step in Endodontic Treatment | From the start of access cavity preparation to the completion of coronal restoration during a single treatment visit (approximately 35-120 minutes). | The duration (in seconds) of each of seven key procedural stages performed during routine root canal treatment on maxillary first molar teeth: 1. Access cavity preparation 2. Working length determination 3. Canal shaping 4. MB2 canal detection and shaping 5. Final irrigation and passive ultrasonic activation 6. Root canal obturation 7. Coronal Restoration The duration of each stage was recorded separately. In addition, the sum of the durations of these seven stages was recorded as the total treatment time. Each stage was timed separately for three groups (direct vision, dental loupes, and dental operating microscope) to compare the effect of different magnification techniques on working efficiency. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Presence of MB2 Canal According to Magnification Technique | Baseline (at the time of canal orifice identification) | The presence or absence of a second mesiobuccal (MB2) canal in maxillary first molar teeth will be recorded for each magnification group (direct vision, dental loupes, and dental operating microscope). The association between the magnification method and MB2 canal detection will be evaluated using the Chi-square test (Monte Carlo simulation). |
