Cone-beam Computed Tomographic Evaluation and Endodontic Management of a Mandibular First Premolar with Type IX Canal Configuration: Case Report
Journal of endodontics, 2017Co-Authors: Aamina Zoya-farook, Prashant Abhishek, Aditya ShahabadiAbstract:Abstract Introduction Mandibular Premolars exhibit considerable variations in their root canal system that can be particularly difficult to diagnose. Avoiding mishaps and successful nonsurgical endodontic therapy depends on an absolute understanding of the root and root canal morphology to locate, prepare, and obturate the canals. Methods This case report describes the endodontic therapy of a mandibular first Premolar with 2 roots and 3 canals with confirmation of cone-beam computed tomography. It also cites the incidence of morphologic variations reported in mandibular first Premolars, based on ethnic diversity. Result Cone-beam computed tomography (axial and sagittal sections) confirmed the presence of 2 roots and 3 canals in a mandibular first Premolar. Here, the main canal divided into 3 root canals at the middle third, otherwise described as Sert and Bayirli's type IX canal configuration. Conclusion The occurrence of documented cases of a mandibular first Premolar with Sert and Bayirli's type IX root canal configuration is rare. Failure to recognize a second and third canal in the present case might have otherwise resulted in endodontic reinfection.

proximity of Premolar roots to maxillary sinus a radiographic survey using cone beam computed tomography
Journal of Endodontics, 2014Co-Authors: Thomas Von Arx, Ivo Fodich, Michael M BornsteinAbstract:Abstract Introduction The proximity of the roots of the posterior maxillary teeth to the maxillary sinus is a constant challenge to the dental practitioner. Because the majority of studies have assessed the relationship regarding molars, the present study focused on Premolars. Methods Cone-beam computed tomographic images of 192 patients were reconstructed in sagittal, coronal, and axial planes to quantify the distances between the root apices of the maxillary Premolars and the adjacent maxillary sinus. Measurements were taken for each root, and data were correlated with age, sex, side, and presence of both or absence of 1 of the 2 Premolars. Results A total of 296 teeth (177 first and 119 second Premolars) were evaluated. The mean distances from buccal roots of the first Premolars to the border of the maxillary sinus in the sagittal, coronal, and axial planes ranged from 5.15 ± 2.99 to 8.28 ± 6.27 mm. From palatal roots, the mean distances ranged from 4.20 ± 3.69 to 7.17 ± 6.14 mm. The mean distances of second Premolars were markedly shorter in buccal roots between 2.32 ± 2.19 and 3.28 ± 3.17 mm and in palatal roots between 2.68 ± 3.58 and 3.80 ± 3.71 mm, respectively. The frequency of a Premolar root protrusion into the maxillary sinus was very low in first Premolars (0%–7.2%) but higher in second Premolars (2.5%–13.6%). Sex, age, side, and presence/absence of Premolars failed to significantly influence the mean distances between Premolar roots and the maxillary sinus. Conclusions Based on the calculated mean distances of the present study, only few Premolars (and if so second Premolars) would present a risk of violating the border of the maxillary sinus during conventional or surgical endodontic treatment or in case of tooth extraction.

diagnosis and root canal treatment of a mandibular second Premolar with three root canals
International Endodontic Journal, 2003Co-Authors: Tina Rodig, Michael HulsmannAbstract:Aim To present a case of a mandibular second Premolar with three root canals. Summary An accurate diagnosis of the morphology of the root canal system is a prerequisite for successful root canal treatment. A review of the literature reveals a low incidence of all types of Premolars with three root canals. Diagnostic means such as preoperative radiographs and examination of the pulp chamber floor aid the location of root canal orifices. The diagnostic and therapeutic problems concerning Premolars with unusual anatomy are described on the basis of a clinical example. A case report describes the successful treatment of a mandibular second Premolar with three root canals. Key learning points • Clinicians should be aware of unusual root canal anatomy in mandibular Premolars. • Radiographs exposed at two different horizontal angles and their careful interpretation facilitate the search of additional root canals. • The use of magnification and additional lighting are recommended for the clinical examination of the pulpal floor.

Mandibular Premolar with three root canals--two case reports.
International endodontic journal, 1992Co-Authors: Kam Chan, Siu-chun Yew, Shou‐yee ChaoAbstract:The presence of three root canals in the mandibular Premolar may sometimes be recognized when there is persistent postoperative discomfort following root canal therapy. This paper presents two cases of root canal treatment of mandibular Premolars with three root canals including one mandibular first Premolar and one mandibular second Premolar. The possibility that there is more than one root canal in lower Premolar teeth must be considered in the radiographic and clinical examination during root canal treatment.
