Abstract:
This review evaluates the effectiveness and clinical applicability of guided endodontics (GE) in managing dental anomalies, which present challenges for conventional endodontics. The primary objective is to assess how GE enhances treatment predictability and minimises errors in cases such as dens invaginatus (DI), dentinogenesis imperfecta (DGI), dentinal dysplasia (DD), dens evaginatus (DE) and dental fusion. A narrative review was conducted using a comprehensive search across PubMed/MEDLINE, Scopus, Web of Science, EMBASE and Cochrane Library databases for studies published 2015-2025. Nine studies met the inclusion criteria. GE was found to offer high success rates in the treatment of DI, DGI and DD. The integration of CBCT and 3D-printed guides allowed for minimally invasive access cavity preparation, reduced iatrogenic complications and improved precision. Despite these advantages, challenges include increased cost, being time-consuming and limitations in curved canals. Guided endodontics holds promise as a transformative technique in modern endodontic practice.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
