adequate cleaning, shaping and filling of the root canal system are mandatory for successful root canal treatment. thorough knowledge of root canal morphology and unusual anatomy of the tooth is critical for the practitioner. the occurrence and location of the third mesial canal (middle mesial canal) in mandibular first and second molars in relation to other two mesial canals that were treated ...

The aim of the present study was to provide a general scheme for pulpectomy of primary molars that may be useful for decision-making about negotiation of root canals and selection of appropriate instruments. A total of 160 vital primary molars in 85 patients (40 males, 45 females) aged 4-6 years were selected. After taking primary radiographs, local anesthesia was induced, and the teeth were is...

AIM To describe the successful non-surgical endodontic management of a permanent maxillary lateral incisor tooth with four root canals. SUMMARY Aberrant morphology of root canals can occur in any tooth, including maxillary lateral incisors. In the presented case, clinical examination and radiographs clearly depicted the presence of four root canals in a right maxillary lateral incisor. The di...

INTRODUCTION A variety of mesial and distal projections have been suggested for separating the canals in a multi-canaled root. But there is no general agreement on the best angulation for each tooth. The purpose of this study was to evaluate the X-ray horizontal angle for separating the canals of four-canal first mandibular molars. MATERIALS AND METHODS Forty four-canaled mandibular molars we...

AIM The aim of this study was to investigate the prevalence of additional canals in maxillary first molars in a selected population in Nigeria. METHODS AND MATERIALS One hundred extracted teeth were collected from the Pedodontic and Oral Surgery clinics of the University College Hospital in Ibadan, Nigeria. The teeth were identified and their root planed to remove adherent soft tissues. Each ...

A mandibular fi rst molar with two distal roots is an interesting example of anatomic variation. This paper describes case reports of mandibular fi rst molar with three roots (one mesial and two distal) and four canals (two in mesial and one in each distobuccal and distolingual root). The canals were shaped with protaper rotary fi les and irrigated with 5.25% sodium hyochlorite, 0.2 %w/v of chl...

Double tooth is a dental anomaly consequent to fusion of two or more teeth or gemination of a single tooth. This report describes a unique case of double tooth in relation to a mandibular lateral incisor exhibiting the presence of four root canals. The role of conventional radiography and advanced three-dimensional imaging techniques in the better assessment of complex root canal systems and th...

introduction: a variety of mesial and distal projections have been suggested for separating the canals in a multi-canaled root. but there is no general agreement on the best angulation for each tooth. the purpose of this study was to evaluate the x-ray horizontal angle for separating the canals of four-canal first mandibular molars. materials and methods: forty four-canaled mandibular molars we...

Knowledge and understanding the anatomical configuration of individual tooth play a significant role in success of endodontic treatment, in addition to through debridement and obturation of the canals. The canal anatomy of maxillary second premolar has been studied extensively, and the presence of a significant variety of multirooted canals is relatively rare in it. A 27-year-old female reporte...

Tooth root canals with endodontic treatment can be reinfected because the continued presence of Enterococcus faecalis biofilm. Many techniques has been proposed to eliminated this bacteria, however, these no offer fully elimination E. faecalis. In pilot study cold plasma was effective in inhibition biofilm infected tooth canals.
