[Acute necrotizing ulcerative gingivitis (ANUG) in HIV antibody-positive subjects]. / Gengivite ulcero-necrotica acuta (GUNA) in soggetti AbHIV positivi.

The paper reports five cases of acute ulcero-necrotic gingivitis in AbHIV-positive subjects and stresses that the frequency of this pathology in the AbHIV-positive population is 0.67% (3.3% if only the homosexual population is taken into consideration) compared to 0.02-0.08% in the normal population. These findings may therefore suggest an association between AUNG and HIV-1 infection.

Epidemiology, clinical features and prognostic value of HIV-1 related oral lesions.

Between February 1987 and February 1990, we studied 737 antibody anti HIV-1 positive (AbHIV+) subjects referred to the Infectious Diseases Institute of the University of Turin (Italy) in order to evaluate types, prevalences, relations with clinical stages, distributions in risk-groups and prognostic significances of HIV-1 related oral lesions. The study evidenced the high prevalence of oral lesions, especially mycoses, in the investigated population: 40.3% of the patients showed, in fact, HIV-1 related oral lesions. The 37 months follow-up of 55 AbHIV+ with oral hairy leukoplakia (HL) and 101 patients with oral candidiasis (OC), demonstrated that the probability of developing AIDS in patient with HL was 0.381 at 15, 0.635 at 25 and 0.824 at 37 months. In the patients with OC the probability was 0.294 at 15 months, 0.524 at 25 and 0.781 at 37 months.

[The oral aspects of osteogenesis imperfecta. A clinical case report]. / Aspetti orali nella osteogenesi imperfetta. Descrizione di un caso clinico.

The oral symptoms observable in patients with imperfect osteogenesis are described and a clinical case that makes a contribution to our knowledge of a rarely encountered pathology is reported.

[Scleroderma: oral manifestations]. / Sclerodermia: manifestazioni orali.

Oral signs of sclerodermia and dental implications are described. The disease can be classified among the collagenopathies and its onset often involves dermatological signs prior to involving other organs and systems.

[Dental reimplantation and transplantation]. / Considerazioni sul reimpianto e trapianto dentario.

Purpose of the inquiry about dental replantation and transplantation and about principal operating methods is to explain to the practice dentist these technics as an extreme help when he is compelled to save a tooth. A logical utilisation of these therapeutic processes will allow, preserving some dental elements esteemed "lost", to postpone as much as possible in time the prosthesis construction and to maintain physiologically look and function of dental arches.

[Physiological aspects of deglutition]. / Aspetti di fisiologia della deglutizione.

[Description of a case of subcutaneous emphysema as a consequence of endodontic treatment]. / Descrizione di un caso di enfisema sottocutaneo come conseguenza di un trattamento endodontico.
