Root canal morphology of primary molars by clearing technique: An in vitro study

Abstract

Vertucci's Type I root canal configurations were most frequently observed.

The Smear Layer Removal Efficiency of Different Concentrations of EDTA in primary teeth: A SEM Study

“…7,19 In addition to the disadvantages of the smear layer, accessory canals in primary roots and the physiological root resorption process cause the unsuccess conditions in endodontic treatment. 14,[20][21][22] Moreover, the difficulties of accessing these areas such as mentioned anatomical variations, ramifications, lateral branches and incomplete seal of the antibacterial filling material increase the need for removal of this layer, especially in primary molar teeth which have more narrow and divergent root canals. 5,6,8,14 Therefore, it was aimed to evaluate the effects of different irrigation materials on smear layer removal in primary teeth in this study.…”

“…It is known that the root canal morphology are quite variable especially in primary molars, and exist numerous ramifications, accessory and lateral canals and branches. 14,[20][21][22]27 In order to ensure that the mentioned variations do not affect the results and to provide the standardization, the use of single rooted upper primary incisors was preferred in the present study. In addition, the increasing opening/widening of apical foramen with physiological root resorption 28 and the inaccessibility problems to apical region are observed in primary teeth.…”

Efficacy of Root Canal Instrumentation and Fracture Strength Assessment in Primary Molars after Preparing Two Different Shapes of Access Cavity: An Ex Vivo Histological Study

“… 18 , 21 One of the predominant causes of failure of root canal treatment in primary molars is the variation in root canal anatomy. 22 In the present study, mean root canal debridement scores of distal roots were less in comparison to that of the mesial root, because the distal canals of primary mandibular molars are flat-oval, predominantly wider buccolingually, narrower mesiodistally, and typically ribbon shaped, 23 which comprises the root canal debridement, especially in the apical regions. 24 Thus, knowledge of the anatomical configuration of the canals is important, to avoid inadequate cleaning and shaping, leaving untouched fins on the buccal and/or lingual aspects of the canals.…”

Análisis de la morfología interna del primer molar superior mediante la técnica de diafanización

“…Conocer a fondo la anatomía de las piezas dentales, es uno de los aspectos fundamentales para conseguir el éxito en la terapia endodóntica, que tiene como uno de sus principales objetivos, realizar una preparación biomecánica que englobe la mayor parte del sistema de conductos radiculares (1) .…”
