Access surgery.

Patient indicated for endodontic treatment of maxillary anterior teeth for aesthetic prosthetic rehabilitation. Thus, an alternative access alternative that provides direct access to the canals was considered, since the preservation of the structure is not a determining factor for the choice of the surgical access technique.

Direct endodontic access technique (La Turno et al., 1985) for anterior teeth in treatment of anterior teeth with restorative/prothetic indication.

In: Mauger et. al. Volume 25, Issue 3, March 1999, Pages 206-207:

The main goals of endodontic access are identifying the canal, obtaining straight-line access to the apical third of the root
canal space, and preserving tooth structure.
Historically, mandibular incisors have been positioned lingually for esthetic and restorative reasons. Anatomy of the mandibular incisors presents a challenge when making endodontic access due to their small size and high prevalence of two canals. Benjamin and Dowson (1) reported that the prevalence of two canals in mandibular incisors is 41.4%. With a lingual access, the lingual canal is often difficult to locate and instrument. When making a lingual access in mandibular incisors, an artificial protrusion of dentin remains making it difficult to detect and debride the lingual canal. Janik advocated extending the lingual access further toward the cingulum to aid in locating and debridement of the lingual canal. canal.

Others recommended a facial access to better locate and debride the anterior teeth. LaTurno and Zillich traced
straight-line access using 50 mandibular incisors. They found that 84% of these teeth would require access placed through the incisalfacial aspect to obtain straight-line access. Clemente and Gilboe discussed performing a labial endodontic access on mandibulaincisors as a means of maintaining and preserving tooth structure on these teeth when a pin crown and core are indicated
