MB2 Canals in Pediatric Maxillary First Molars
Sponsor: Sümeyra Akkoç
Summary
This study examined how often an additional root canal, known as the second mesiobuccal canal (MB2), could be found in the upper first permanent molars of children aged 10-15 years. During root canal treatment, an endodontist followed a step-by-step approach using a standard clinical examination, magnifying loupes, a dental microscope, and, when clinically necessary, three-dimensional dental imaging. The study evaluated how much each step contributed to locating and confirming the canal.

Stepwise MB2 Clinical Confirmation Protocol
The MB2 canal was assessed sequentially using: Stage 1, direct clinical examination without magnification; Stage 2, selective dentin removal under dental loupes at ×4 magnification using ultrasonic instrumentation; Stage 3, selective dentin removal under a dental operating microscope at ×16 magnification; and Stage 4, clinically indicated CBCT assessment followed, when radiographic evidence of an MB2 canal was observed, by CBCT-guided re-examination under the dental operating microscope. Clinical confirmation required identification of an orifice separate from the MB1 canal and negotiation of the canal to the working length.
