PURPOSE The objective of this study was to compare postobturation flare-ups following single and two-visit endodontic treatment of molar teeth with periapical radiolucency. MATERIALS AND METHODS A total of 100 patients with asymptomatic molar teeth with periapical radiolucency were selected. They were randomly allocated into two groups. Fifty patients received complete endodontic treatment in...

Recent advances in endodontic instrumentation have simplified the treatment process and improved long-term success. Ten years ago the vast majority of endodontic instrumentation was being performed with hand files and reamers. Today, most practitioners providing endodontic therapy are utilizing rotary instrumentation.

OBJECTIVES Scientometric methods and the resulting citations have been applied to investigate the scientific performance of a nation. The present study was designed to collect the statistical information of dental articles by Iranian authors published in PubMed. MATERIALS AND METHODS We searched the PubMed database for dental articles of Iranian authors until June 31, 2015. All abstracts were...

Non-surgical Endodontic therapies have a very good success rate. In some cases failures may occur which can be managed by non-surgical endodontic re-treatment or endodontic surgical intervention. Intentional replantation is an accepted procedure in which a tooth is extracted and treated outside the oral cavity, then reinserted into its socket to correct an obvious radiographic or clinical endod...

Maintenance of dental health has attracted attention researchers at present. Various materials have been constructed and applied for curing different diseases, although limitation biocompatibility safety is still a big challenge. To overcome these limitations, nanomaterials with unique properties are incorporated into various treatment used in applications, including endodontic treatment, perio...

BACKGROUND Orofacial pain is a common encounter in dentistry (affecting 12% of the population) and is a primary reason for patients seeking emergency care. Dentists often prescribe oral analgesics, which have disadvantages of decreased absorption rates and delayed onset. Intranasal (IN) delivery takes advantage of a large surface area of mucosal tissue for rapid absorption. The purpose of this ...

Long-term success of endodontic treatment is strictly dependent on proper shaping and cleaning of the root canal system followed by obturation of entire prepared space. Anatomical variations should be considered during radiographic and clinical evaluation as parts of endodontic treatment. A mandibular premolar with three canals is quite rare and such a tooth requires special canal preparation a...

Generally, mandibular first molars have one mesial and distal root but in few cases there are morphological variations where the number of roots canals may vary. Radix Entomolaris (RE) is presence of an additional lingual distally molars. Correct diagnosis important before starting with endodontic therapy these teeth to ensure successful treatment outcome. This case report series describes the ...

Including students' perceptions in the educational process is considered a key component in monitoring the quality of academic programs. This study aimed to evaluate the concept of one's learning experience in endodontic teaching from the perspective of a group of Brazilian students. A total of 126 self-administered, structured questionnaires were distributed to undergraduate dental students en...

It was the purpose of this study to determine if a periodontal abscess could be differentiated from an endodontic abscess by the types and proportion of microorganisms found in the abscess exudate in darkfield microscopic examination. Dental abscesses with draining sinus tracts in 17 patients were studied. Eight of the abscesses were diagnosed clinically to be of endodontic origin and nine peri...
