The C-shaped canal system is an anatomical variation mostly seen in mandibular second molars, although it can also occur in maxillary and other mandibular molars. Such variation in the root canal anatomy is uncommon in mandibular first premolars and very rare in mandibular second premolars. The C-shaped canal is so named for the cross-sectional morphology of the root and root canal. The main an...

Purpose: The study was designed to investigate the relationship between root resorption patterns of deciduous mandibular molars and position of erupting permanent successors by a Radiographic Evaluation. Methods: A total of 250 radiographs of primary mandibular molars (126 first molars and 124 second molars) of 5to 12-year-old patients were evaluated. The root resorption pattern and the premola...

Comprehensive knowledge about the variations of morphology and anatomy of the roots and root canal systems in permanent teeth is an important factor to reach successful outcome. The aim of this case report was to explain nonsurgical endodontic treatment and long term follow-up of a mandibular second premolar with unusual root and root canal morphology. 10-year-old girl was referred with a compl...

Success of endodontic treatment requires the knowledge and morphology of root canal anatomy. Undetected additional canals in mandibular premolar is a common reason for endodontic failure. This presents with diagnostic difficulty and subsequent flare ups and poor prognosis. Location of additional canals is the key to successful endodontic management. This case report describes endodontic managem...

PURPOSE The purpose of this study was to identify the complex course of the mandibular canal using 3D reconstruction of microCT images and to provide the diagram for clinicians to help them understand at the interforaminal region in Korean. MATERIALS AND METHODS Twenty-six hemimandibles obtained from cadavers were examined using microCT, and the images were reconstructed. At both the midpoint...

Dentigerous Cyst/developmental cyst of benign odontogenic origin are ones that surround the crown of impacted, embedded, unerupted or developing teeth. Dentigerous cyst is second most common cyst of the oral cavity after radicular cyst. They are usually solitary in occurrence and mostly associated with the mandibular third molars. Dentigerous cysts involving impacted second premolars are rarely...

The otherwise considered being one of the smallest and weakest teeth in the arch, mandibular second premolars have been found to almost double its size in macrodontia. Such anomalies of morphological alterations have caused the teeth to be more weak and prone to diseases, as accredited to the increased surface area and particular morphology. Bilateral mandibular second premolar macrodontia is a...

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...

Macrodontia (megadontia, megalodontia, mac rodontism) is a rare shape anomaly that has been used to describe dental gigantism. Mandibular second premolars show an elevated variability of crown morphology, as are its eruptive potential and final position in the dental arch. To date, only eight cases of isolated macrodontia of second premolars have been reported in the literature. This case repor...
