RESUMO
The pituitary gland's role as a functional matrix for sella turcica has not been suggested in orthodontic literature. This paper is an attempt to correlate the role of pituitary gland in the development of sella turcica. A case report of dwarfism associated with hypopituitarism is presented to highlight the above hypothesis.
RESUMO
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.
RESUMO
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.
