A contribution to the radiological diagnosis and surgical treatment of necrotising enteritis of the newborn

Advanced dental caries is the main cause that leads to tooth loss and extractions, therefore it is important to diagnose and treat this condition on time. Dental caries often differs from other diseases in that it can be diagnosed only when it requires surgical treatment. Detection and treatment of incipient carious lessions is very rare in practice. Radiography is an indispensable paraclinical examination in the detection of carious lesions because a thorough clinical examination is not possible for all dental surfaces. The relief of the occlusal surfaces and the limited access to the proximal surfaces make the detection of carious lesions during a clinical examination very difficult. Numerous clinical studies have shown that a radiological examination can reveal carious lesions that would otherwise remain undetected both in occlusal and proximal surfaces. About 50% of interproximal carious lessions cannot be identified during clinical examination and require radiological investigations.

Nasopalatine Duct Cyst

Background. Nasopalatine duct cyst is a developmental, nonodontogenic cyst of jaw. Case report. We presented a 46-year-old male with nasopalatine duct cyst. The clinical examination revealed fluctuant swellings of the anterior palate, without pain, 4?5 cm in diametar. Both radiographs showed the presence of an ovoid radiolucency located in the midline of the maxilla between the roots of central maxillary incisor teeth with peripheral sclerosis, 25 ? 35 cm in diametar. Surgical treatment was performed under local anaesthesia (ArticainchloridumTM 4% ? 3M ESPE) using a palatine approach. Postoperatively, no paresthesia of the anterior palate in inervation area of nasopalatine nerve was registrated. Pathohistologic findings proved both clinical and radiological diagnosis. Conclusion. Nasopalatine duct cyst is a rare lesion which slowly develops. The diagnosis is mainly based on radiography, tooth vitality testing and histologic findings. After a correctly applied clinical diagnosis procedure and surgicel treatment, recurrence is rare.

Scanning Electron

The recent development of the scanning electron microscope has added great impetus to the study of ultrastructural details of normal human ossicles. A thorough description of the ultrastructure of the human ossicles is required in order to determine changes associated with disease processes following medical or surgical treatment.Human stapes crura were obtained at the time of surgery for clinical otosclerosis and from human cadaver material. The specimens to be examined by the scanning electron microscope were fixed immediately in the operating room in a cold phosphate buffered 2% gluteraldehyde solution, washed with Ringers, post fixed in cold 1% osmic acid and dehydrated in graded alcohol. Specimens were transferred from alcohol to a series of increasing concentrations of ethyl alcohol and amyl acetate. The tissue was then critical point dried, secured to aluminum stubs and coated with gold, approximately 150A thick on a rotating stage in a vacuum evaporator. The specimens were then studied with the Kent-Cambridge S4-10 Scanning Electron Microscope at an accelerating voltage of 20KV.
