Use of spiral computed tomography for multiplanar dental reconstruction.

OBJECTIVE: To compare spiral with conventional CT for multiplanar reconstruction (MPR) prior to dental implant placement. METHODS: Ten patients underwent conventional and then Spiral CT at 1 mm slice thickness. In six patients (Group A) the pitch was 1:1; the other four (Group B) it was 2:1. Image quality and clinical features were evaluated separately on axial and reconstructed images by two experienced radiologists who scored each parameter from 1 (poor, non-diagnostic) to 3 (good, diagnostic). RESULTS: Loss of spatial resolution with spiral CT was not significant and the diagnostic yield poorer only for trabecular bone structure. The MPRs were better and depiction of the mandibular canal more reliable. CONCLUSIONS: We recommend the use of spiral CT instead of conventional CT for dental MPR because examination time is shorter and patient comfort is improved. Use of a pitch of 2:1 permits a marked reduction in X-ray dose with no loss of image quality.

[Focal pathology and infectious dental foci. Theoretical and clinical aspects].

A relationship between bucco-dental infection and distant tissue lesions has been recognized for many years. However the pathogenesis of focal odontostomatogenous infection is still not fully understood. At the moment a special attention is paid to the auto immune pathogenesis, but, how focal infection could cause distant tissue injury remains to be investigated. The importance of prevention of infective endocarditis is underlined and prophylaxis procedures are discussed.

[Oral pathology of pscyhosomatic origin. Review of the literature].

Emotional stress is one of the etiologic or anyway predisposing factors involved in a lot of oral pathologies. In fact, relations between stress effects and frequent diseases such as gastric ulcer or ulcerous colitis are today wellknown by everyone. Theories about a relation between this kind of etiology and tumours are only reported by some Authors and are at the level of hypotheses. Mouth is very weak in these situations, owing to its great interest as primary erogenous zone, and for this reason we find frequently oral pathologies in relation with psychosomatic medicine. In this report we tried to give a good help to the study of these diseases and to find an easy classification to use (really it is an hard work to do due to the variety of this numerous illnesses).

[Brown tumor of the upper jaw. Surgical-rehabilitation problems].

The Authors describe etiology, pathogenesis and main clinical aspects of brown tumors in patients with chronic renal failure. Then, by presenting two cases of patients with secondary hyperparathyroidism and brown tumors of upper maxillary bone, they report the measures to be applied for the surgical treatment and prosthetic management of these patients. In both cases the patients have been undergone a radical resection of a brown tumor of the palate. After maxillectomy have been successfully applied at first an interim obturator prosthesis and then, approximately three months later the definitive obturator prosthesis.
