[Diagnostic significance of secretory IgA coated yeast cells in oral candidiasis].

The significance of in vivo IgA coated yeast cells for the diagnosis of candidiasis of the oral mucosal membranes was evaluated by direct immunofluorescence in 42 patients with or without clinical symptoms, shown to be positive for yeast growth in the cultural test. Most of the patients with clinically suspected candidiasis of the mucosal membranes gave positive results by serologic assays in contrast to the majority of symptomless patients. The diagnostic approach proved to be essentially consistent with the clinical signs, persistance of infection, response to antifungal therapy and quantitative cultural data.

[Retained canine. Surgical exposure and guided traction].

The Authors, after making a distinction between retained and included canine, examine the local and general causes of retention; moreover they illustrate clinical and radiological methods to reach the correct diagnosis; finally they highlight the importance of parodontal tissues during surgical treatment and particularly they describe a clinical case of surgical exposure and subsequent "under mucosal traction" on an intermediate retained canine.

[Morpho-functional characteristics of bacterial species of major importance in endodontic infections].

Most of the bacteria involved in the endodontic infection can be considered as "highly specific", for they appear to be almost irrelevant in the large field of the other human disease from infection. Namely the most important anaerobia responsible for endodontic infection are: Bacteroides, Fusobacterium, Peptostreptococcus, and Veillonella. The group of Bacteroides is composed by several species with different metabolic and genetic characteristics. They are Gram-, non-motile, non-spore-forming rods. Fusobacterium are spindle-shaped, Gram-, non motile, non-spore-forming bacilli. Peptostreptococci are round-shaped, Gram+, non-motile cocci. Veillonella are small, Gram-, non-motile cocci.

[Mixed infection: specific canal aspects].

The fundamental feature of the bacteriologic flora that causes endodontic lesions is its mixed nature. It has been demonstrated that a mixed flora can more easily give rise to both acute and chronic inflammatory reactions. The coexistence of different families of bacteria within the same environment is based upon a very delicate balance given by the interplay of the various mechanisms of bacterial relationships: mutualism (symbiosis and commensalism), antagonism and synergism. The metabolic needs (nutritive and respiratory) of the different types of bacteria which cause endodontic infections are so specific that these organisms are strictly dependent on each other for their own survival in the radicular canal system and for their pathogenicity.

[Significance of the bacterial flora in the etiology of apical periodontitis. Qualitative, quantitative and topographical aspects].

In the international literature it is shown the central role of root canal infection in the etiology of periapical lesions. As a matter of fact it has been proved (13) that sterile necrotic pulp tissue is completely unable to cause inflammatory reactions at the periapex. Infection of endodontic origin extends to the supporting tissues of the tooth only in the case of their acute inflammation (e.g. acute apical periodontitis, acute alveolar abscess, phoenix abscess). On the other hand in chronic inflammation bacteria remain confined in the endodontic space. Only few exceptions to this general rule have been experimentally proved. In endodontics we deal with a mixed infection which is composed by obligate anaerobes and by facultative anaerobes. The most frequently found obligate anaerobes are Bacteroides sp. and Fusobacterium sp. (Gram- rods) Anaerobic Diphtheroides (Gram+ rods) Peptostreptococcus sp. (Gram+ cocci) and Veilonella sp. (Gram- cocci). Actinomyces sp., Lactobacillus sp., Streptococcus sp., and Staphilococcus sp. are the facultative anaerobes most frequently found.

[Papillomas of the oral cavity. Role of the papillomavirus].

Latest results about etipatogenesis of oral papillomas make us to modify the old classification according which papillomatosis were traumatic or idiopathic, giving to the latest a tested viral origin. Studies at the electron microscopy, immunoperoxidase technique and DNA-hybridization showed that human papillomavirus (HPV) is the etiologic agent of these oral lesions. Many works seem to support the opinion that HPV could be implicated even in the development of some oral carcionomas; anyway, further confirmatory evidence is still needed.

[Benign neoplasms of the soft tissues of the oral cavity].

The Authors, starting from a statistical study of Gennari et al., point out the frequency of the benign neoformations in the soft tissue of the oral cavity. They describe then the most frequently findable histological forms and the problems posed to the clinic and the surgeon by some histological forms such as the mixed tumours of the minor salivary glands and the fibropapillomatosis of the vestibular fornices. The Authors conclude stating that they not always are harmless neoformations and easily surgically excisable.

[Clinical, etiopathogenetic and anatomopathological considerations in primary cheilitis].

Among the wide range of stomatitis and mucositis there are lesions, defined as primary cheilitis, affecting mainly the lips. Specific topographic and structural features of the involved area determine their appearance. The Authors revient contact-related cheilitis, actinic-related cheilitis, glandular and suppurative cheilitis, granulomatous and exfoliative cheilitis. They point out the principle clinical, etiopathogenetic and histopathologic features. From their overview it arises, that in modern literature, funy detailed contributions are definitively lacking. Symptomatic medical treatments are a clear reflection of many etiological doubis. Surgical therapy is advised only in chronic actinic-related cheilitis and in deep-rooted glandular cheilitis. In granulomatous cheilitis surgical treatment is indicated once a permanent lip deformity occurs.

[Malignant centro-facial granuloma. Clinical contribution].

The mid-face malignant granuloma represents an exceptionally rare disease. Its etiology is unknown and the prognosis is dismal. Characteristics pathological features are represented by granulomatous, ulcerative and lesions, with a destroying tendency. The AA., in reporting a recently observed case of the disease, stress the difficulties encountered in the diagnosis and analyze its clinical course typically showing relapsing episodes. Therapeutic strategies adopted in the various phases of the disease are discussed.

[Current opinions concerning some pathological conditions of the mouth].

The mucosal pathological lesions of oral cavity in literature are reviewed and the Authors report about etiopathogenesis, development and clinic of herpetic infection, oral candidosis, lichen and white spongious naevus. They discuss the utility of a combined clinic among stomatologist, internist and dermatologist in order to have a satisfactory treatment of the diagnosed illness.

[Lesions of the oral mucosa caused by drugs and drug combinations].

The drugs and drug combinations responsible for cutaneo-mucosae reactions are extremely numerous and only the most frequently responsible are mentioned. Pathogenic processes are described: immune-allergic, overdosing, idiosynerasy, drug interactions, etc... Alterations provoked are various and vary from erythema up to acute skin necrosis. We would suggest caution, in prescribing drugs and drug combinations.

[Current orientations in endodontics].

The Authors, after having underlined the importance of the endodontic discipline, that allows to obtain a reliable rehabilitation, illustrate the Schilder technique, used by them at the Odontoiatric Clinic, University of Brescia. The AA. take into consideration and face the problem of the reintervention on channels already treated, as well as the periapical infections complication. They conclude saying that endodoncy is an extremely difficult discipline, because it implies a lot of experience, practical ability and a constant application.

[Germectomy of the 3d molar in orthodontics: contrasting opinions in the literature and personal considerations].

In the orthodontic practice one of the controversial points is if the third molar tooth can contribute to the development of a bad occlusion or determine a relapse of a ranging, above all in the fore segment of the dental arch. The Author, after taking into consideration the favourable and the contrary subjects to an eventual germectomy of the octaves with the prophylactic or the therapeutical purpose, he finishes declaring that you can't accept a strictness of position. In fact if you can consider the utility of the germectomy in some particular cases, you mustn't yet accuse the third molar tooth to be the only cause of a bad occlusion.

Functional disturbances of the inferior alveolar nerve after sagittal osteotomy of the mandibular ramus: operating technique for prevention.

The high frequency of permanent functional disturbance of the inferior alveolar nerve after sagittal osteotomy of the mandibular ramus is a disadvantage to which attention is always drawn in the different operating statistics. The authors, on the basis of previous experimental research, and in order to reduce the incidence of this disadvantage, have carried out sagittal osteotomy of the ramus in a series of patients by performing the splitting of the two cortical plates using a thin cement spatula as a chisel. The results have been extremely encouraging as the authors have observed only one case of permanent functional deficit of the inferior alveolar nerve and they have even noticed a very low incidence of temporary impairment.
