The aesthetic and functional restoration in the case of partial edentulism in young patients.

The absence of teeth in youths can be due to congenital absence, traumas, caries and periodontitis. The loss of a tooth in growing patients can cause both aesthetic-functional and psychological problems, particularly if the teeth of the anterior region are involved. When there is the loss of a dental element in a teenager it is necessary to provide a quick suitable therapeutic solution, which will be different in comparison to an adult because of the changes related to the growth of the maxillary bones. The aim of this paper is the analysis of the several therapies which can be carried out on young patients with partial edentulism, paying particular attention to the conditions and the indications which allow an implant prosthesis restoration.

Radiotherapy for maxillo-facial hemangiomas in children. Dental and periodontal long term effects.

Vascular maxillo-facial malformations, common pathologies in children, represent 7% of all benign tumors. They are divided into vascular malformations and hemangiomas. In the 70s-80s radiotherapy was the most applied technique, but because of its misuse or overdose, it could lead to relevant and hard consequences for the impact on the salivar glands, periodontium and growing maxillo-facial nuclei. The authors describe the case of a 38-year-old man, who, during infancy, was submitted to radiotherapy for a hemangioma to his chin and cheek. He was under observation for an agressive periodontitis, followed by a serious facial asimmetry, located in his irradiated side. They describe the therapy and the results obtained, underlying the particular difficulties detected in operating on tissues hardly and often irreversibly injured by radiotherapy. On the basis of this clinical case and of the most up-dated knowledge, therapeutical alternatives such as embolization, cryotherapy, cortisonic systemic and intralesional therapy, the use of interferon gamma 2 and the use of the most recent laser, are analyzed, and advantages and disadvantages and the most appropriate indications are underlined.

[Squamous cell carcinoma of the lip. Retrospective analysis of 42 cases].

BACKGROUND: To examine to what extent physicians follow a regional guidelines for the diagnosis, staging, treatment and follow-up of patients with squamous cell carcinoma of the lower and upper lip. METHODS DESIGN: retrospective analysis of data from the medical records of 42 patients diagnosed with squamous cell carcinoma of the lower and upper lip during the period 1990-2000. SETTING: Department of head and neck pathology, oral cavity and audio-verbal communication of Naples University. PARTICIPANTS: the data were collected by this Department. RESULTS: In accordance with the TNM system, the 50% of cases was in stage T1, 33% in T2, 14% in T3. In few cases (3%) the lesion was in stage T4. All cases were in M0 and only 8% of cases presented nodal disease at diagnosis (N1). The type of treatment in relation to age was in agreement with the guidelines in 34% of cases. Of the 42 surgically-treated patients, only 4 showed, after 12 months, a local recurrence. CONCLUSIONS: Prognosis is good if squamous carcinoma is diagnosed early.

Localized osteodysplasia of the mandible in a seven-year-old child: a case report.

AIM: This report concerns the most recent knowledge on osteodysplasies, anomalies in the development of the bone tissue, that may concern one or more skeleton segments affecting children. CASE REPORT: The case of a 7-year-old patient is reported, whose left hemimandible showed a radio transparency with a size of 10 x 7 mm. After the usual preliminary diagnostic investigations, it was decided to carry out an ablation. The neoplastic formation was completely enucleated using a conservative operation technique.

[Tooth replantation after traumatic exarticulation. Present therapeutic orientations and future perspectives].

Replantation is a method in which an avulsed dental element is replaced into its alveolar socket. The dental traumatic exarticulation occurs in any age, but most frequently in the juvenile population. The aim of this paper is to rewiew the risks and benefits of tooth replantation and to discuss the present therapeutic orientations and future perspectives for avulsion management.

Supernumerary teeth "mesiodens". Case report.

The supernumerary tooth is an anomaly of dental eruption that is not rare to find in the clinical practice. Among the supernumerary teeth the "mesiodens" is most frequent. The mesiodens is found in the region of the superior central incisors and it can be the cause of many complications. The aim of this work is the description of a rare symptomatic case of mesiodens and the diagnostic and therapeutic strategies to adopt when this dental anomaly occurs. In particular the authors suggest making radiographic examinations only in the family of patients with dental anomalies of number, thinking that the incidence of such anomalies is too low to justify mass radiographic examinations.

[Circulating biomarkers association in the follow-up of patients with oral cancer].

The goal of this study is to analyze the importance of circulating biomarkers association in the management of patients affected by oral cancer. In this study a survey is made of the international experience from 1980 to 1990 based on the presence of CEA, LASA, SCC Ag, TPA, ferritina, CA-50 and others in patients affected by oral cancer and the sensitivity and specificity of these circulating biomarkers association are assessed. In patients with active disease, the results obtained at the time of diagnosis of oral cancer are not satisfactory due to poor specificity of these circulating biomarkers association. The conclusions is drawn that the circulating biomarkers association (especially CEA, SCC Ag, LASA, ferritin, TPA and CA-50) appears to be useful in the prognosis and staging of oral cancer, while their presence is not significative for the diagnosis.

[Pleomorphic adenoma of the parotid gland in childhood].

BACKGROUND: The authors report the results of ten years' activity at the Pedodontic Surgery Unit in the Institute of Maxillofacial Surgery at the Second University of Naples and analyse the possibility of conservative treatment of pleomorphic adenoma in childhood. METHODS: The study includes 614 cases of salivary gland pathology. The authors illustrate the epidemiological, clinical and therapeutic characteristics of this type of lesion in childhood, emphasising that the data emerging from this study do not differ from the clinical and therapeutic management of pleomorphic adenoma in young patients reported in the literature. RESULTS: In particular, they emphasise that satisfactory therapeutic results can be achieved using conservative techniques, like conservative superficial parotidectomy. CONCLUSIONS: Conservative superficial parotidectomy has the advantage of being less radical and traumatic for a young patient, without provoking a significant increase in recidivation.

Metastases to the human mandible.

Two clinical cases are reported of mandibular swelling caused by metastatic jaw neoplasms. They analyse. The clinical characteristics of the swelling are analysed and all laboratory and radiographic tests performed are examined. It is concluded that metastatic localisations in the maxillofacial bone are very rare, but that the mandible is certainly the most frequent site. The authors also highlight the fact that the presence of metastatic lesions in the jaw may be the first symptom of the neoplastic disease.

[The role of soft tissues in the planning of bimaxillary orthognathic surgery. Review of the literature and two clinical cases].

The authors have investigated the clinical role of the soft tissues and of their influence in the planning phase of the orthognathic surgery, with the purpose to emphasize their capital influence in the face armony. Most of the patients really ask for an aesthetic result, that is in a tight relation with the correct prediction of the morphological changes of the soft tissues. The aesthetics excite nowadays the research, especially in all the surgical fields, and so the orthognatic surgery is more than ever from the soft tissues influenced. Subsequently the authors have investigated the principal indications to the bimaxillary surgery and have suggested a personal diagnostic-therapeutic protocol for a correct and opportune evaluation of the soft tissues relations. Finally the authors have described the whole prediction phase and have shown as the maxillary bones influence the whole facial skelett, and as frequently the chin correction and the rhinoplasty are necessary for a better result in the time.

[Clinical applications compared in implantology].

On the basis of their own experience and of orientation reported by literature, the authors display how important it is for professional men who practise implantology or who approach it, to have the possibility of knowing several implantologic systems. Indeed, what we want to demonstrate is, that in different situations of edentulous, in relation to the quantity and the quality of the available bones, to the gnotologic situation and to the aesthetic functional result they aim to, corresponds the choice of one or several implantologic systems. In that sense the basic research occupies a role of vital importance, because only through the knowledge of chemical, chemical-physical and biomechanical characteristics it is possible to recognize some essential chemical entities for an implantologic approach. Thus the several diagnostic instrumental means available enable the surgeon to make an exact clinical diagnosis. The TAC, in this case, assumes a determinant role, because, in addition to supplying exact dimensional and qualitative informations, also occupies an important medico-legal aspect. The resolution of some forms of edentulous programmed like that, will subsequently be illustrated. Finally, a control hypothesis is proposed for the rearrangement, of peri-implant bone. On this account, the SPECT (single photon emission computerized tomography), through a semi-quantitative research, could provide some specific indications about the osteotropic implantation activity.

[A case of a carcinoma arising in lichen planus in a subject with diabetes mellitus and arterial hypertension (Grinspan's syndrome)].

The authors describe a clinical case observed at the Inst of Oral & Maxillofacial Surgery characterized by three simultaneous symptoms: arterious hypertension, diabetes mellitus, oral erosive lichen planus. Grinspan & his co-workers observed this syndrome. The results of their research were exposed at the Congress on Dermatology in Buenos Aires, 1963. In 1965 in a repetitive study Grupper & Avul seemed confirm the existence of this symptomatological triad; therefore the authors defined this complex as "Grinspan's syndrome". Further researches conducted by other authors (Jolly, Powell. Howell e Rick) confirmed the association hypertension-diabetes-"erosive" lichen. However there were other worthwhile studies (Lozada-Nur, Christensen) which emphasized a not significant high frequency of patients with diabetes and high blood pressure and the oral sugar tolerance like random specimens of common people. Besides the authors notice that their clinical case is interesting not only because of their simultaneous presence of the three symptoms but also because of the bioptic appearance of a cancer likely appeared on a pre-existing inveterate lichenoid lesion.
