Mandibular premolars usually have a single root and canal. Complex root canal system with atypical variations is a common finding among them. Failure to identify such a one can affect the prognosis of endodontic treatment. Apart from knowledge and sophisticated instruments, a good clinical expertise is required in identifying, tracing and treating such a root canal system. This case report is o...

background and aims. the knowledge of variations in root canal morphology is critical for a successful endodontic treatment. the purpose of this study was to investigate variations in the root canal system of human mandibular first permanent molars in an iranian population. materials and methods. in this study, 209 mandibular first molar teeth were decalcified, dye-injected, and cleared in orde...

OBJECTIVE The aim of the present study is to assess the root and root canal morphology of maxillary and mandibular premolars in a Turkish population by using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this study, CBCT images of 2134 premolars (987 maxillary, 1147 mandibular) were obtained from 404 patients. Details of gender, age, number of roots and canals, and canal conf...

HYBROSONIC : The name derives from Heat + Sonic Vibration. The invention relates to Root Canal Obturating Device for fillling of Root Canal after removal of tooth pulp. Root canal treatment is the removal of tooth’s pulp, a small thread like tissue in the centre of the tooth. Proper root canal filling should achieve three dimensional obturation of the root canal space to prevent micro organisms...

the aim of this study was to report the endodontic management of right maxillary central incisor having two canals with vertucci canal configuration type iv . internal morphology of root canals is variable and often complex. therefore, to achieve a technically satisfactory endodontic outcome, the clinician must have adequate knowledge of the internal canal morphology and its variations in order...

introduction: the aim of this study was to identify the root and canal morphology of maxillary first and second molars in iranian population by taking and analyzing cone-beam computed tomography (cbct) scans. methods and materials: extracted maxillary first ( n =125) and second ( n =125) molars were collected from native iranians and scanned by using a cbct scanner. the number of roots and conf...

The variability of root canal system morphology of multirooted teeth represents a continuous challenge to endodontic diagnosis and therapeutics. This report extends the range of known possible anatomical variations to include teeth with lesser number of root and root canals. Variations of root canal systems need not always be in the form of extra canals. Clinicians should be aware that there is...

objectives: this study aimed to assess and compare the apical sealing ability of herofill® soft-core system and lateral condensation technique in fine curved canals using the fluid filtration method. materials and methods: forty human mesiobuccal root canals of mandibular first molars with 25° to 40° curvatures were instrumented to an apical size 30/0.04. roots were randomly assigned to two exp...

Maxillary lateral incisors usually exhibit a single root with a single canal. However, maxillary lateral incisor teeth with unusual morphology of root canal system are frequently reported. These cases of variable root canal anatomy can be treated well by nonsurgical endodontic methods. A detailed description of root canal morphology is fundamental for successful endodontic treatment. Treatment ...

The purpose of this paper is to provide useful information that will enable dentists to predictably shape root canals for three-dimensional obturation of the root canal system. The information is intended to help clinicians better understand when and how to safely use Nickel-Titanium (NiTi) rotary shaping instruments. This article is intended to enhance clinical performance for all dentists who...
