human mandibular premolars have earned the reputation for having an extremely complex root and root canal morphology. the incidence of multiple roots and canals in mandibular second premolars is lower than those in mandibular first premolars. mandibular second premolars with three root canals and separate foramina are very rare. in this case report, endodontic management of a three-rooted mandi...

PURPOSE Although intracoronal radiolucencies in radiographs of unerupted teeth have been reported for several decades, the prevalence of this condition remains unknown. This study determined the prevalence and associated dental conditions of permanent teeth showing pre-eruptive dentin radiolucencies in bite-wing radiographs of school children attending two school dental therapy training centers...

we report the delayed eruption and infraocclusion of a mandibular second primary molar with ectopic location of the permanent successor. this was a rare case where the second premolar was located to the distal side of the impacted mandibular second primary molar. early intervention is recommended to manage orofacial disfigurement and prevent consequent problems.

presence of extra roots and canals should be considered before initiation of root canal treatment for the success of endodontic treatment. a mandibular second premolar with three separate roots is very rare and its prevalence has been reported to be around 0.1%. this case report explains non-surgical endodontic treatment of a mandibular second premolar with three separate roots and three separa...

The aim of this study was to analyze the efficiency of the mandibular banded and cast splint anchorage forms used in Herbst treatment. The records of 16 Class II:1 subjects treated with mandibular banded premolar anchorage (group A), 19 Class II:1 subjects treated with mandibular banded premolar-molar anchorage (group B), 34 Class II:1 subjects (group C), and 18 Class 11:2 subjects treated with...

The mandibular second premolar is usually described as a single rooted tooth with a single root canal. However, two root canals may be found but the occurrence of two roots is extremely rare. The reported studies have shown 0.3% prevalence of two roots in mandibular second premolars. This report describes an unusual case of a thirteen year old female patient with bilateral two rooted mandibular...

Complex root canal system with atypical variations is a common finding among mandibular premolars. Endodontic treatment in these teeth may not be successful due to the failure to recognise and treat multiple canals. This paper presents endodontic treatment of a mandibular second premolar with three roots and three canals.
