Root and canal morphology of Indian maxillary premolars by a modified root canal staining technique

Abstract: 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 magnificat… Show more

“…These frequencies were similar to those reported in some studies (25, 38, 39) but much higher than findings reported elsewhere (7,8,(12)(13)(14)(15)(16)40) (Table 4). These differences in root canal anatomy highlight the influence of ethnic background on the root morphology of maxillary premolars.…”

“…Several studies (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19) have reported that maxillary premolars have a highly variable internal canal configuration, which can vary according to race and geographic origin (8,9,12). The reported prevalence of maxillary first premolars with 1 root ranges from 22% to 66%, with 2 roots from 33% to 84%, and with 3 roots from 0% to 6% (7,8,11,12,16,17,20).…”

“…Muitas técnicas têm sido empregadas para o estudo da anatomia dental, principalmente do endodonto. Entre estas, têm sido incluídos estudos radiográficos, desgastes, cortes histológicos, diafanização, injeção de corantes associados ou não à diafanização, técnicas de processamento digital, isótopos radioativos, microscopia eletrônica e tomografia computadorizada, segundo Neelakantan et al 8 .…”

“…Clearly, in terms of endodontic management, it is critical to define the number of roots and not just canals, as this will have clinical implications when interpreting radiographs, during access cavity preparation and when searching for the location of canal orifices (9,15). Notably, three-rooted maxillary premolars can exist in two formstwo buccal roots and one palatal root, or one buccal root and two palatal roots (16,17). In summary, it is unclear why buccal and palatal roots were not defined separately in maxillary premolars in the Vertucci classification, while mesiobuccal, distobuccal and palatal roots were considered separately in maxillary molars.…”
