Brief Summary

Aim: Evaluation of the effect of different obturation techniques on postoperative pain level and radiographic healing on non-surgical endodontic retreatment (NSER) applied in a single visit in teeth with single root canal and apical periodontitis (AP). Materials and Methods: 63 teeth with single-root canal and AP from 50 systemically healthy patients (mean age 34.19±9.75 years; 27 women, 23 men) were included in the study. Residual root canal filling materials were removed with retreatment files. All teeth were prepared using rotary files . The teeth were randomly divided into three groups according to the obturation technique; cold lateral compaction (CLC), continuous wave compaction (CWC), and gutta-core (TGC). Restorations are completed using direct composite resin in the same visit. In all cases, pain status were evaluated using the Numerical Pain Rating Scale (NRS) at preoperative, postoperative, 3rd hour, 24th hour, 48th hour, and 7th day. Periapical index (PAI) scores were recorded on preoperative and postoperative 6-month on the periapical radiographs for cases. Data were analyzed as statistically. Significance level was determined as p \< 0.05.

Outcome Measures

Primary Outcomes (2)

• Evaluation of postoperative pain that may occur due to treatment

  In this study, postoperative pain observed after treatment was measured using the Numeric Rating Scale (NRS).

  1 week

• Radiographic evaluation of healing of periapical tissues at 6 months after treatment

  In this study, periapical radiographs obtained using a parallel film holder before and after treatment of the patients included in the study were evaluated according to the Periapical Index (PAI) scores.

  6 months

Study Arms (3)

Cold Lateral Compaction (Control group)

EXPERIMENTAL

After the root canal preparation was completed, the working length was checked with the master cone and periapical radiography. The master cone was then covered with root canal sealer and placed in the root canal. Then, a gap was created for the .02 angled lateral cones using #30, 25 and 20 finger spreader. The obturation process continued until the spreader went 2 mm beyond the level of the canal orifice. Next, a hot excavator removed the coronal gutta-percha 1 mm below the canal orifice.

Warm Vertical Compaction

EXPERIMENTAL

After the root canal preparation was completed, the working length was checked with the master cone and periapical radiography. Root canal sealer was applied to the root canal walls using a master cone. HeatPlugger connected to the down-pack unit of the obturation system was adjusted to be 4 mm shorter than the working length. The master cone was cut 1 mm shorter than the working length with a heated plugger and applied to the root canal. Then, the heated plugger was advanced in the apical direction, and the apical region was obturated. Obturation was completed in 2 stages with gutta-percha in the gutta-percha cartridge connected to the remaining root canal cavity back-fill unit and heated to 200 °C. Heated gutta-percha was vertically condensed with HeatPlugger to 1 in the first stage and 2 in the second. The root canal obturation was completed by removing the gutta-percha 1 mm below the canal orifice.

Other: Single Visit Non Surgical Root Canal Treatment Protocol

Gutta Core

EXPERIMENTAL

After the root canal preparation was completed, the working length was controlled with the master cone and periapical radiography. Root canal sealer was applied to the root canal walls using a master cone. Root canal obturation was completed with heated gutta-percha according to the manufacturer's instructions. The heated gutta-percha was slowly inserted into the canal up to the working length. After cutting the handle of the obturators at the level of the canal orifice with a hot excavator, it was condensed into the canal using a gutta-percha plugger. The coronal gutta-percha was removed 1 mm below the canal orifice using a hot excavator.
