$$\rightleftharpoonup{xx}$$ $$\longleftharp{xx}$$, $$\longrightharp{xx}$$,

This study compared the single-tip bioceramic filling and AH-Plus hot vertical compaction methods in treating second mesiobuccal canal root canals of maxillary first molars. The single-tip group showed higher optimal filling rates, shorter procedure time, and reduced postoperative pain, confirming it as a safe, effective, and efficient treatment option.

摘要

$$\rightleftharpoonup{xx}$$ $$\longleftharp{xx}$$, $$\longrightharp{xx}$$,

This study aimed to assess the clinical efficacy of the single-tip bioceramic filling method in treating the second mesiobuccal canal (MB2) of maxillary first molars. Ninety-four patients requiring MB2 root canal therapy were randomly allocated to either an experimental group (n = 47) or a control group (n = 47) between January 2023 and December 2024. The experimental group was treated using the single-tip bioceramic technique, whereas the control group received AH-Plus hot vertical compaction. The primary outcome measures included filling quality, procedure time, postoperative pain at 24 hours and 7 days, and clinical efficacy at 6 months. The experimental group demonstrated a significantly higher optimal filling rate (P < 0.05) and shorter mean procedure duration, with comparable clinical success between both groups at 6 months. Additionally, patients in the experimental group experienced lower postoperative discomfort within 24 hours (P < 0.001). Overall, the single-tip bioceramic filling technique achieved equivalent clinical outcomes with improved procedural efficiency and patient comfort compared with the conventional AH Plus vertical compaction method. This simplified technique may represent a safe, effective, and time-efficient approach for MB2 canal obturation in maxillary first molars.

引言

$$\rightleftharpoonup{xx}$$ $$\longleftharp{xx}$$, $$\longrightharp{xx}$$,

Root canal therapy serves as the primary treatment approach for periapical diseases affecting the pulp1, with the goal of thoroughly cleaning the root canal system and performing a three-dimensional hermetic seal to prevent reinfection2. Maxillary first molars are the earliest permanent molars to erupt in the mouth3, which play a key role in maintaining a normal occlusal relationship, and root canal treatment is often required clinically due to caries, defects, and fissures.

The second mesiobuccal (MB2) canal is highly prevalent in maxillary first molars

Filling quality comparison

As shown in Table 1 and Figure 1, the overall filling quality differed significantly between the two groups. In the experimental group, 93.62% (95% CI: 88.2–97.0) of canals achieved an optimal fill, compared with 85.11% (95% CI: 78.0–90.6) in the control group. Overfilled canals were fewer in the experimental group (6.38% [95% CI: 3.0–11.8]) than in the control group (14.89% [95% CI: 9.4–22.0]). Statisti.......

讨论

$$\rightleftharpoonup{xx}$$ $$\longleftharp{xx}$$, $$\longrightharp{xx}$$,

The morphology of root canals in maxillary first permanent molars is notably intricate, especially within the MB roots, where the occurrence of MB2 canals exhibits significant variability across studies, with reported rates between 51% and 90%11,13,14,15. This variability can be attributed to differences in race, age, detection methods, sample size, and the absence of a standardized definition .......
