TL;DR: It was observed that it is challenging to diagnose a cutaneous draining sinus tract of endodontic origin, and proper disinfection of the root canal system by chemo-mechanical instrumentation resulted in resolution of the Sinus tract and promoted periapical healing of the tooth involved.
Abstract: Aim: To report an uncommon case of an extraoral sinus tract of the submandibular region caused by a molar in the mandible (tooth 47).
Case report: Tooth 47 presented with an insufficient coronal restoration and an absence of pain and discomfort to pressure and palpation in the periapical region. Based on oral inspection and radiographic examination, a pulp necrosis of tooth 47 was diagnosed, which had resulted in a cutaneous sinus tract. The persistent purulent drainage of the sinus tract in the submandibular region ceased during the successful root canal treatment of tooth 47. The root canal was irrigated with copious rrigant (3% sodium hypochlorite, 0.9% sodium chloride, 2% chlorhexidine) and several intracanal calcium hydroxide dressings.
Conclusion: In the presented case it was observed that it is challenging to diagnose a cutaneous draining sinus tract of endodontic origin. Thus, treatment of skin lesions of the face, and neck odontogenic infections should always be considered. Clinical and radiographic dental examinations can identify the tooth involved and may avoid unnecessary antibiotic or surgical therapies. Proper disinfection of the root canal system by chemo-mechanical instrumentation resulted in resolution of the sinus tract and promoted periapical healing of the tooth involved. This should therefore be considered as the treatment of choice when dealing with an odontogenic extraoral sinus tract.

TL;DR: A case in which all four maxillary incisors were having Type II canal configurations (Vertucci's classification) is reported and a large periapical lesion was seen in relation to the right lateral incisor.
Abstract: The prevalent notion about maxillary central incisor with normal external morphology is a tooth with single root and root canal. A case in which all four maxillary incisors were having Type II canal configurations (Vertucci's classification) is reported, in addition, the lateral incisors revealed dens invaginatus with a Type I pattern as suggested by Ohler's classification and a large periapical lesion was seen in relation to the right lateral incisor. The diagnosis was confirmed with the aid of spiral computed tomography (CT) and canals obturated. Nonsurgical healing of the lesion was assessed by reviewing the case at prefixed intervals of time.

TL;DR: Sixty-four randomly selected cases were evaluated and allocated to one of two groups, where bacterial load on the canal walls was sampled using endodontic files and samples were cultured for facultative anaerobic bacteria.
Abstract: Sixty-four randomly selected cases were evaluated and allocated to one of two groups. In Group 1, after gaining access to the root canal, bacterial load on the canal walls was sampled using endodontic files. A further sample was taken after apex location and initial widening of the canal had been completed and the photo-activated disinfection process carried out. A final sample was taken after completion of the canal preparation using citric acid and sodium hypochlorite solutions. In Group 2, the initial sample was taken as described previously. A second sample was taken after conventional preparation using 20% citric acid and sodium hypochlorite solutions as co-irrigants. A final sample was then taken after a subsequent PAD treatment. All samples were cultured for facultative anaerobic bacteria.

TL;DR: A glass ionomer-based sealer powder for root canal filling is proposed in this paper, which is capable of being easily removed from the root canal if a root canal retreatment is needed.
Abstract: PROBLEM TO BE SOLVED: To provide a glass ionomer-based sealer powder for root canal filling, capable for being easily removed from the root canal if the root canal retreatment is needed, and having seal property and bio-compatibility of the dental glass ionomer cement powder used as a conventional sealer for root canal filling SOLUTION: The glass ionomer-based sealer powder for root canal filling comprises fluoroaminosilicate glass powder compounded in polymer unable to react with polycarboxylic acid such as bees wax, polyisoprene, polyisoprene copolymer, polystyrene, natural gutta-percha, carnauba wax, castor wax, shellac, dammar gum, copal gum, and/or an inorganic filler unable to react with polycarboxylic acid such as diatomite, talc or pearlite The compounded amount is 2 to 70% by weight
