Polymorphous adenocarcinoma is a slow growing malignant tumor of minor salivary glands. The most common location these tumors palate, buccal mucosa, upper lip, floor mouth and retromolar region. This neoplasm characterized by cytological uniformity, architectural diversity infiltrative growth pattern. case report polymorphous occurring in lacrimal gland. They are seldom reported this propose un...

STUDY OBJECTIVE The aim was to compare the costs and effects of management of intractable urinary incontinence by urinary catheterisation or incontinence pads. DESIGN This was a prospective, randomised study comparing catheterisation with pads, supplemented by additional data collected from patients with chronic indwelling catheters. Main outcome measures were costs of equipment, nursing time...

the object of this work is to present a study of the thermomechanical behavior of the automobile disc brake for the prediction of their resistance to fatigue. then, a study of purely mechanical dry contact between the disc and pads is developed with a good prediction becomes a major stake for the industrialists while modeling the loading and the boundary conditions around the disc.we used the s...

Human mandibular morphology is often thought to reflect mainly function, and to be of lesser value in studies of population history. Previous descriptions of human mandibles showed variation in ramal height and breadth to be the strongest difference among recent human groups. Several mandibular traits that differentiate Neanderthals from modern humans include greater robusticity, a receding sym...

A 42-year-old man presented with pain and swelling in the left lower back tooth region. He underwent uneventful extraction of impacted tooth 1 year before. There was a well-defined dome shaped swelling of size 1.5 cm × 2.5 cm in the left side posterior alveolar ridge. Lesional aspiration revealed a thick mucus aspirate. Computed tomography revealed significant buccal and lingual cortex destruct...

The possibility of using osseointegrated implants for orthodontic anchorage is well known. When absolute orthodontic anchorage is needed, mini-implants can be inserted in the non-alveolar bone area (e.g. palatal process or retromolar areas of the mandible). However, what happens to these implants at the end of treatment can be a problem as neither trephine explantation nor simply leaving the su...

Third molar teeth are causative factors of many oral pathologies. Lower third molars are the most often retained teeth and the origin of considerable pain. The aim of the study is a presentation of the morphology of third molars with incompletely formed apices on the basis of panoramic radiograms. The material comprised routine panoramic radiograms taken in the years 1996-2000. In the cases whe...
