RESUMEN
Dentigerous cyst is a fairly common odontogenic cyst with an uncomplicated prognosis. However, reports of odontogenic and non-odontogenic tumors arising from the cysts have been published for many years. Therefore, the importance of thorough histopathological examination and regular follow-up cannot be overemphasized. Here is a case report of a possible development of desmoplastic ameloblastoma from a dentigerous cyst. This case is unique for two main reasons. Firstly, to our knowledge such a case has not been reported previously. Secondly, the tumor seemed to arise from the capsule and not from lining of the dentigerous cyst. Transformation of odontogenic rests into cysts is known to occur in the syndromic cases of odontogenic keratocysts (resulting in recurrent and daughter cysts) but not in dentigerous cysts. This case report may prompt greater interest in the role of the supposedly inactive odontogenic nests in the capsule of these cysts.
RESUMEN
Developmental anomalies in the hard tissue are seen frequently in dental practice. Gemination and fusion are the most commonly encountered anomalies, and distinction between the two is always challenging. Gemination, also called double tooth, is an anomaly exhibiting two joined crowns and usually a single root. It represents an incomplete attempt of a single tooth germ to split. It is considered multifactorial in etiology, with genetic and environmental causes. This paper discusses a rare example of bilateral gemination (prevalence 0.04%) of maxillary central incisors with completely separated roots. Multidisciplinary care ensured a successful esthetic and functional outcome.
RESUMEN
Parry Romberg syndrome is a rare disorder of unknown etiology, seen most commonly as an asymmetry of the face, rarely affecting the limbs. Trophic malfunction of sympathetic system has been proposed as a cause. The syndrome presents with characteristic skeletal, dental, and soft tissue changes in the affected half of the face, with or without neurological signs and symptoms. Imaging studies sometimes reveal lesions in the brain corresponding with the neurological defects. The disfiguring nature of the disease Results in psychological disturbance and communication disorders like speech defects, as also dental anomalies. The present article reports such a case of an 8-year-old girl who presented with mainly hard tissue changes, without neurological or intraoral soft tissue changes. There has to be prompt multi-disciplinary management of such cases keeping in mind development, aesthetics, speech, and masticatory function, along with symptomatic treatment of neurological deficits.
