“…The methods used in analyzing the root canal morphology are canal staining and tooth clearing (10-12); conventional radiographs (13,14); alternative radiographic techniques (15)(16)(17); radiographic assessment enhanced with contrast media (18); and, more recently, computed tomographic techniques (19,20). The most commonly used technique is canal staining and clearing because of its accuracy (4,(10)(11)(12)21).…”

“…Variations of root canal anatomy and root morphology as a function of race are well established. 1 Numerous methods have been used for studying root canal anatomy, including canal staining and tooth clearing, [3][4][5] conventional radiographs, 6,7 alternative radiographic techniques, [8][9][10] radiographic assessment enhanced with contrast media 11 and, more recently, computed tomographic techniques 12,13 and modifi ed root canal staining technique. 14 The most commonly used technique is canal staining and clearing, because of its accuracy.…”

The aim of this study was to investigate the root and canal morphology of maxillary first and second premolars in Indians by a modified canal staining and tooth clearing technique. Maxillary first (350) and second (350) premolars were collected, and the morphology and number of roots analyzed. After cleaning, the teeth were immersed in India ink and placed in a hyperbaric oxygen chamber at 0.6 MPa for 2 h. The teeth were then demineralized and cleared. Digital images of the teeth were examined under magnification to evaluate the number of root canals, root canal system configurations, number of apical foramina, and intercanal communications. Root canal configurations were identified based on Vertucci's classification and Gulabivala's additional classes. The most common root morphology of the first premolars was the classical two separate root morphology (a Caucasian trait) and that of the second premolars was a single-root morphology (a Mongoloid trait), though other morphologies such as singlerooted first premolars and three-rooted first and second premolars were also identified. A "radiculous" first premolar was identified in two samples. The buccal roots of the first premolar showed the maximum variation, the most common being type I (Vertucci's classification), followed by type IV. The highest incidence of intercanal communications was found in the single-rooted first premolars. All roots exhibiting type IV and V canal configurations showed two separate apical foramina, while additional type 2-3 canal configurations showed three separate apical foramina. The root number and morphology as well as the canal morphology of Indian maxillary premolars showed both Mongolian and Caucasian traits.

“…14 This was because of the superimposition of the mandibular alveolar bone, even though preoperative radiographs indicated the presence of a C-shaped root. 22,25,26 In this study, the main reason for the failure of the intentional replantation of C-shaped root canal seemed to be the periodontal bone breakdown (data not shown). Ricucci et al demonstrated that periodontal involvement was the cause of failure when conventional root canal treatment of C-shaped mandibular molar cases was followed-up for 1 year.…”

Objectives:The purpose of this retrospective study was to evaluate the success rate of intentionally replanted mandibular second molar with C-shaped canal configurations and to access the impact of preoperative periapical lesion on the success of intentional replantation procedure. Materials and Methods: This retrospective chart review study evaluated 52 intentionally replanted mandibular second molar teeth treated at Seoul National University Dental Hospital Department of Conservative Dentistry from January 2005 to December 2007. Seventeen teeth were lost for the follow-up, and another 6 teeth did not meet inclusion criteria of C-shaped root canal configurations. Healing outcome such as success, uncertain healing, and failure after follow-up was evaluated by clinical criteria and radiographs. Results: The overall success rate was 72.4% for the 29 intentionally replanted C-shaped mandibular second molars. The success rate of replanted teeth with preoperative periapical lesions was similar to that of replanted teeth which have no periapical lesions. Conclusions: Therefore, root canal treatment failure on C-shaped mandibular second molar can be predictably treated by intentional replantation regardless of the presence of periapical lesion.
