ABSTRACT
Fusion imaging is the amalgamation of various advanced imaging modalities used in oral and maxillofacial imaging today, which takes a lion share in improvising diagnostic and formulation of effective treatment outcomes. In today’s scenario, this has been widely accepted in various disciplines of dentistry in a broadened horizon for capturing the head and neck pathologies. This review paper therefore aims to highlight various aspects of fusion imaging with its bird’s view in various dental specialties
ABSTRACT
Sonographic elastography is a new technique for measurement of the tissue stiffness, and is currently under investigation for tissue characterization in several anatomic sites. In recent years, real-time Ultrasonography elastography (USE) modes have appeared on commercially available clinical ultrasound machines, stimulating an explosion of research into potential oncologic and non-oncologic clinical applications of USE. Preliminary evidence suggests that USE can differentiate benign and malignant conditions accurately in several different tissues. The principles underlying elastography are that tissue compression produces strain (displacement) within the tissue – which is lower in harder tissues than in softer tissues and that malignant tissues are generally harder than normal surrounding tissue. Therefore, elastography might yield clinical information useful in diagnosing cervical metastasis and improving prognosis in oral cancer .The purpose of this review is to highlight a promising new ultrasound technique, known as elastography, which measures the characteristics of tissue compliance.
ABSTRACT
Peripheral ameloblastoma, a rare and unusual variant of odontogenic tumour, comprises about 1% of all ameloblastomas. The extraosseous location is the peculiar feature of this type of tumour, which is otherwise similar to the classical ameloblastoma. It appears in the gingiva and oral mucosa and it usually does not show any bone involvement on radiographs, except for saucer shaped erosion of underlying alveolar bone. Recurrence is considered uncommon. We report a case of peripheral ameloblastoma of maxillary gingiva.
