Dentigerous cyst involving mandibular second permanent molar: A case report

Dentigerous cyst is the most common developmental odontogenic cyst, frequently noted as an incidental finding on radiographs. It commonly affects the permanent mandibular third molars and maxillary canines. We present a case of a dentigerous cyst involving an impacted mandibular second molar in a 21-year-old female

Inverted and impacted supernumerary tooth: Case report

Inverted teeth have been reported in both maxilla and mandible and mostly they are inverted and impacted third molars and premolars. However, a few cases of inverted supernumerary teeth attached to an impacted third molar have been reported. This case report would add to the academic literature and case series on inverted and impacted teeth. The present case reports an inverted and impacted supernumerary tooth attached to a third molar in a middle-aged male patient

Recurrent peripheral cemento-ossifying fibroma

Peripheral cement-ossifying fibroma (PCOF) is a rare osteogenic neoplasm that ordinarily presents as an epulis-like growth. It frequently occurs in maxillary anterior region in teenagers and young adults. We report a case of PCOF in a 42-year-old male, which was previously surgically excised and recurred after a period of 2 years. PCOF should be considered in the differential diagnosis of reactive hyperplastic lesions originating from gingiva. Hence, early diagnosis with proper surgical excision and aggressive curettage of the adjacent tissues is essential for prevention of recurrence

Accidental separation and lodgment of rotary endodontic file into the dentist's thumb

Separation of the endodontic instrument within the root canal system and sharp injuries to the dentist is not an uncommon event in endodontic practice. Although root canal instruments can fracture at any stage of endodontic treatment, its fracture within the dentist's hand is a very rare event. An unusual case of accidental separation and lodgment of rotary endodontic file in the dentist's thumb is presented along with its management. A 33-year-old dentist reported with an accidental lodgment of rotary endodontic file into his thumb. The fractured instrument was removed successfully by a surgeon. The present case describes a rare event of occupational risk in endodontic practice

Infected dentigerous cyst associated with a horizontal impacted ectopic supernumerary tooth induced by trauma to the maxillary incisors: A rare case report

Dentigerous cyst is known to be caused by the accumulation of fluid between the epithelium and the crown of an unerupted tooth. Its size increases by the expansion of the follicle, and it is attached to the neck of the tooth. These cysts are often associated with impacted third molars and maxillary canines and rarely with supernumerary teeth. In the present paper, we report a case of a dentigerous cyst associated with an impacted ectopic supernumerary tooth. This cyst was missed initially due to a failed root canal treatment associated with the nonvital maxillary central incisor. This case of a cystic lesion can create a dilemma between radicular and dentigerous cyst. The pathogenesis of the ectopic tooth, differential diagnosis, and management are also discussed
