Lesioni neoplastiche della mucosa orale.Testo atlante
No full texti tumori della mucosa orale costituiscono un capitolo di grande interesse per la elevata incidenza, l'ampio spettro delle manifestazioni cliniche, la varietà dei quadri istopatologici , l'impegno terapeutico e per la complessità biologica tipica di un'area di transizione cutaneo-mucosale, ricca di strutture differenziate
Clinical evidence and literature to compare two different therapeutic protocols in tooth avulsion.
No full textAIM: This is to assess the priority in tooth avulsion: replantation as quickly as possible and deferred endodontic treatment, or replantation and elimination of every irritating stimulus for the periodontal ligament. The objective is to establish a univocal protocol by analysing and comparing the various components of these therapeutic procedures. MATERIALS AND METHODS: Study design: 20 patients were selected and divided into 2 groups: in group A we focused our attention on the rapidity of replantation, in group B we focused on the elimination of the necrotic pulp and every possible irritating stimulus that might lead to root resorption of inflammatory nature. RESULTS: Clinically, dental mobility seems to be greater in the first group. However after 15 days teeth have a comparable mobility and after one month they all show a mobility degree 1. Radiographically a greater incidence of resorption can be observed in group A compared to group B as in the first one a higher number of replanted teeth undergo resorption. Such lesions have the tendency to remain constant or even increase. CONCLUSIONS: The results of this study seem to take only one direction: extraoral endodontic therapy
Studio epidemiologico sulla prevalenza della patologia cariosa nella popolazione scolastica modenese
No full textNel 1979 il WHO e il FDI World Dental Federation annunciarono gli obiettivi per la salute orale: 6 goals entro l’anno 2000 tra cui si poneva particolare attenzione alla patologia cariosa nei pazienti in età pediatrica, all’età di 12 anni infatti è possibile effettuare uno studio a larga scala, in quanto si è ancora nelle scuole dell’obbligo e si è completata l’eruzione dei permanenti ad eccezione dei terzi molari.La prima mappa globale fu presentata nel 1969 mostrando la prevalenza di carie nei paesi industrializzati e nei paesi in via di sviluppo.Da allora ad oggi si sono susseguiti molteplici studi che permettono di avere un database a livello mondiale molto accurato.Il presente studio si inserisce in questa scia e vuole cercare di dare un quadro della situazione modenese riprendendo i parametri e le metodologie proposte dal WHO
Oral pemphigus
No full textThe involvement of the oral mucosa in patients affected by pemphigus vulgaris (PV), paraneoplastic, IgA pemphigus, and in some cases iatrogenic pemphigus is common and often a prelude to skin lesions. Intraepidermal bullae are caused by acantholysis, induced by IgG autoantibodies directed against the desmosomes and the domain of numerous keratinocytes self-antigens desmogleins (namely cadherins), thus supporting the autoimmune nature of the disease. Apoptosis may contribute to the acantholysis. Oral mucosal lesions are more commonly refractory to treatment compared to skin lesions and have been associated with disease duration, disease location and possibly the presence of HSV DNA in the oral cavity. Recent publications have stressed the positive role of Rituximab in early disease treatment
Utilizzo di Mineral Trioxide Aggregate nella riparazione di perforazioni della forcazione: due casi clinici
No full textAims: Mineral Trioxide Aggregate (MTA), a Portland Cement-like materi- al, developed in 1993 by M. Torabine- jad, has been suggested in the treat- ment of furcal perforation. The aim of this study is to describe two case reports of teeth with furcal perforation treated with mineral trioxide aggre- gate.
Clinical cases: two molars with a furcal perforation, due to decay and iatro- genic mistake, respectively, were treated with Mineral Trioxide Aggregate during the conventional retreatment. Clinical and radiological controls show the healing of periodontal tissues.
Conclusions: the MTA seems to be the best material in the treatment of furcal perforation. Its excellent action may be connected with highly reduced quantity of liquid and bacterial leak- age, and this clinical condition seems to allow the healing of periodontal tissues

[Tooth disorders in ectodermal dysplasias]
No full textRecently, the molecular bases of the most frequent ectodermal dysplasias have been identified; they involve genes responsible for the epithelial morphogenesis, and the regulation of cell survival and proliferation. Teeth alterations with characteristic features are often observed in X-linked anhidrotic ectodermic dysplasia and in autosomic recessive anhidrotic ectoderma, rarely in hidrotic ectodermal dysplasia

Crown fracture and stratification of composite restorations: replication of natural aesthetics
No full textPresenting problemTraumatic dental injuries are frequent accidents that typically involve the maxillary anterior segment, where the most common injuries are crown fractures.Treatment of the dental trauma is complex and requires a comprehensive and accurate diagnostic and treatment plan.It is also important to consider the biological, functional, aesthetic and economic aspects, as well as the patient’s desire.Clinical managementThe success depends on a harmonious integration of various elements, including a thorough knowledge of the internal structure of natural dentition, aesthetics, characteristics of current materials, and restorative techniques.A natural appearing aesthetics result can be achieved in a relatively simple and predictable manner: anatomic stratification with successive layers of dentin, enamel, and incisal composite.General dentists might find the proposed techniques to be complicated and demanding because bonding techniques are still considered intricate, sensitive and unpredictable.This doubt can be overcome by the application of the “natural layering concept” which makes use of only two basic masses, dentin and enamel, perfectly mimicking natural tooth structure.The objective of this article is to present a personalized technique of stratification for each individual case in direct composite restorations.DiscussionThe presented protocol makes highly aesthetic restorations simple yet predictable. Identification and reproduction of the natural anatomy and nuance colour characteristics exhibited by natural dentition with composite resin, thought a detailed evaluation of hue, chroma, opalescence and fluorescence, allow the dentist to satisfy most aesthetic demands and it offers an interesting alternative, minimizing invasiveness, chair time and costs for patients
Teeth and oral mucosa in neurocutaneous syndromes, metabolic diseases and in diseases with defects of DNA repair [La mucosa orale e i denti in sindromi neurocutanee, malattie metaboliche e nelle malattie caratterizzate da difetti di riparo del DNA.]
No full textOral mucosa is frequently involved in a group of genetic diseases, which affect the skin and other organs, particularly the central nervous system. The lesions may be of characterized by inflammations in neurocutaneous syndromes and by tumoral lesions in those diseases with defects of DNA repair. The teeth are mainly involved in progeria, while jaw keratocysts are highly characteristic in Gorlin's syndrome
