A case of giant ameloblastoma: destructive effect on the facial skeleton and soft tissues of the head and neck.

Ameloblastoma is a benign odontogenic tumor characterized by slow growth causing painless facial swelling. The tumor can behave locally aggressively, and may have direct destructive effects on the surrounding soft and hard tissues. This paper reports the unique case of a female patient with giant ameloblastoma of the mandible.

Three-dimensional CAD/CAM imaging of the maxillary sinus in ageing process.

Objectives: During the physiological ageing process atrophy of the alveolar bone appears in vertical direction. This bone resorption causes pushing the limits of the maxillary sinus at the expense of a degraded bone. The sinus volume increases due to the facial development in children and adolescents or during the ageing process due to the loss of teeth and bone mass.

Unilateral occurrence of five different thyroid arteries-a need of terminological systematization: a case report.

This article highlights an unusual and unilateral variation in the blood supply to the inferior portion of the thyroid gland observed on the right lobe during anatomy dissection course. The rare variation of the occurrence of two anomalous arteries: the middle thyroid artery and the aberrant accessory inferior thyroid artery, and one uncommon variant, the thyroid ima artery, was detected in an adult female cadaver. The two generally constant arteries, the superior thyroid artery and the inferior thyroid artery, have been found in their usual anatomical location.

Anatomical study of the roots of cranial parasympathetic ganglia: a contribution to medical education.

A major key to increasing the safety of cranial surgery is a thorough understanding of anatomy. The anatomy of the head is of fundamental interest to dental and medical students early in their studies. Clinically, it is mostly relevant to surgeons who are performing interventions and reconstruction in the maxillofacial region, skull base, and the orbit.

NADPH-d activity in rat thymus after the application of retinoid acid.

The aim of this work was to determine the localization of nicotinamide-adenine dinucleotide phosphate-diaphorase (NADPH-d) activity as the marker for synthesis of nitric oxide synthase (NOS) in the rat thymus after the application of retinoid acid (RA) on 1st, 7th, 14th and 21st days of gestation. The given results can build the basis for understanding of the role of NOS in rat thymus. NADPH-d positive cells were represented with dark-blue color and were localized on corticomedullar junction of the thymus.
