A new technique for the study of periapical bone lesions: ultrasound real time imaging.

AIM: This study describes the use of a real time-ultrasound imaging technique (echography) for the study of periradicular lesions. METHODOLOGY: Twelve patients with periapical lesions of endodontic origin, diagnosed with conventional clinical and radiographic examination, were examined further using echography at the site of the diagnosed lesions. Each lesion was echographically characterized and described by an expert echographist together with an endodontist. Once the major echographic features were identified, information on the size of the lesion, its content, and its vascular supply was obtained and recorded. A tentative differential diagnosis between a cyst and a granuloma was made based on the data. RESULTS: In all cases it was possible to obtain an echographic image. It was also possible to measure the lesions, to evaluate their content and to view their vascularization in different regions of the mouth. CONCLUSIONS: Ultrasound real time imaging is a promising diagnostic technique in endodontology, but further work is required to refine the process.

[Idiopathic osteosclerosis in jaw bones. Clinical statistic study on a population of Sardinian origin].

BACKGROUND: Idiopathic Osteosclerosis are localized, non-expansive and asymptomatic areas of bone radio-opacity, whose aetiology is unknown. The aim of this study was to assess its frequency, and distribution according to its location and to patients' age and gender, in a sample of patients native in Sardinia. METHODS: 697 consecutive clinical records of patients who underwent odontological treatment at the Department of Odontostomatologic Sciences at Cagliari University, over a 10-year period were studied. The panoramic radiographs attached to the clinical records were examined and searched for all cases that showed radio-opacity areas in maxillary bones that could be identified as idiopathic osteosclerosis (IO). RESULTS: By examining orthopantomographies we have located 58 IOs. We found no significant differences between the sexes; average age was 37.8 years. The mandible has proved to be the most affected site (98.2%) in the first molar tooth region (34.5%), followed by the premolar teeth region (25.9%) and of the second molar tooth (15.5%). The lesions examined had an average diameter of 8.8 mm. CONCLUSIONS: IO frequency has proved to be slightly higher than that reported in other articles, though remaining significantly lower than the values reported in Eastern populations. From the clinical point of view, IOs have been identified as sporadic radiographic findings without any real pathological relevance, except for one case in which the lesion caused nervous compression and dental retention, so that it was necessary to administer specific treatment.

[Microcystic lateral parodontal cyst. Report of a case].

The lateral periodontal cyst (LPC) is an odontogenetic lesion of the maxillary bone representing about 0.8% of maxillary cystic lesions. It starts in the lateral periodontal area of a vital erupted tooth. Clinical symptoms are generally absent. Its diagnosis usually can be made on the basis of an occasional radiographic examination which shows an osteolytic monoloculate lesion with defined outlines. The botryoid cyst is a variation of LPC and is radiographically different and more aggressive than the common LPC. A clinical case of LPC which allows to make histopathological and clinical considerations on these cystic lesions is described.

[Fibrous dysplasia of the maxillofacial bones. Clinical considerations].

OBJECTIVE: After a wide survey of the literature, the results of a clinical-statistic study carried out on twelve cases of maxillo-facial bones fibrous dysplasia, diagnosed and treated at the Oral and Maxillo-Facial Surgery Department of the II University of Naples, are reported. EXPERIMENTAL ASSAY: Retrospective study. MATERIALS AND METHODS: All the patients examined showed fibro-osseus lesions involving the mandible in eight cases, the maxilla in three cases and the frontal bone in one case. Seven patients were females and five males, aged between nine and seventy-two years. The surgical treatment was carried out on eleven patients: four cases were treated by complete surgical excision of the fibro-osseous lesions and seven cases by a conservative removal of the portion of the lesion contributing to the bone deformity. RESULTS AND CONCLUSIONS: All cases examined involved maxillo-facial skeleton structures as a sole localization, confirming that the polyostotic forms are more infrequent than the maxillary monostotic ones. The distribution of the cases according to age classes and lesion localization showed a higher incidence of fibrous dysplasia in the third decade of life and a clear predilection for the mandible. The observation of active lesions in old age shows that the disease may evolve also after the growth. The cases treated by radical excision of the lesions have not been followed from relapse; on the contrary three of the seven cases treated by conservative excision relapsed after a few years.

[The departmental concept in the therapy of facial dysmorphisms. A preliminary note on the psychological aspects].

The authors describe the work carried out with the intention of map and border in simple and repeatable way the risk of dissatisfaction in the patient candidates to cosmetic and oro-maxillo-facial surgery. It represent the first of a series of notes which propose to characterize patients with problems tied to the organization of the individuality in which, the discrepancy among expectations and obtained result, lead in the more serious cases, to a real crisis of identity or a depressed state of varied entity.

[Experience with a rigid fixation device in maxillofacial surgery using shape-memory clips].

BACKGROUND: A device of alloy with shape-memorising effect (SME) was utilized in the surgical correction of maxillo-facial fractures. Nitinol, an alloy of equal atomic parts nickel and titanium, is a metal with the unusual property of shape memory. This alloy may be easily bent when cooled in its lower temperature phase and it resumes its original shape when heated in its higher temperature phase. A lot of useful properties of nitinol alloy, such the ability to convert heat energy into mechanical energy, as the biocompatibility and bioinertness, as the anti corrosive stability and high mechanical strength, suggest that it can be useful in the surgical fixation of maxillofacial bone injuries. METHODS: The fixing device of alloy with SME, the indications and the techniques of osteosynthesis and some cases have been discussed by the authors. RESULTS AND CONCLUSIONS: The results of this study showed that the surgical treatment of maxillo-facial bone fractures by devices of shape memory alloys is simple, ensures a good stability of fracture surfaces, reduces the time period of operative procedures and of patients rehabilitation, allowing rapid bone healing.

[Enteral nutrition in maxillofacial oncology].

The authors present a review regarding knowledge of malnutrition in maxillofacial oncology. The causes of nutritional deficit in head and neck tumor derived from metabolic alteration, consequent to the presence neoplasia and antineoplastic therapy. They analyze how to evaluate clinical status in malnutrition patients and they show different therapeutic strategy. The authors emphasise advantages and disadvantages of EN and TPN and present their nutritional forms, based on the EN, analyzing the characteristics.
