Antibiotic prophylaxis in dentistry and oral surgery: use and misuse

INTRODUCTION: Antibiotic prophylaxis (AP) still represents a common but often misused procedure in dental practice, thus aggravating the risk for antimicrobial resistance and adverse effects occurrence. AIMS AND METHODS: Our primary objective is to review the available scientific evidence regarding AP in dentistry both among healthy subjects and medically compromised patients. Additionally, the latest available guidelines provided by some of the most authoritative associations are here discussed. RESULTS AND CONCLUSIONS: AP is advisable only in a small percentage of patients where a risk of severe infective complications (i.e. infective endocarditis and prosthetic joint infection, septicaem…

Uncommon diagnosis of Kaposi’s Sarcoma in a HIV-negative adult patient

Kaposi’s Sarcoma (KS) has been described as a multifocal malignant neoplasm, originating from vascular endothelial cells. Four clinical types has been recognized: classic, endemic, iatrogenic and epidemic1. Classic KS has been reported mainly in patients from Mediterranean area and it typically manifests as cutaneous lesions involving the lower extremities and trunk. Classic KS affects only rarely the head and neck region and few cases have been reported as primary oral classic KS. Oral lesions are localized typically in the hard palate (95%), and more rarely they affects the gingiva and the oro-pharynx. Early oral early lesions typically appear as flat pigmented macules of purple or bluish…

Oral amelanotic melanoma: a case report

Objectives. Primary oral melanoma is a very rare malignancy, representing about 0.5% of all melanomas, characterized by a wide clinical-histological variability and a very aggressive behavior. Aim of the present study is to describe a case of oral amelanotic melanoma, an infrequent variant with a poorer prognosis than that of pigmented melanomas for a more aggressive biological behavior and frequent delays for the correct diagnosis and for starting the treatment. Case report. A 53-year-old white man referred at the Department Surgical, Oncological and Oral Sciences for a macular, scarsely pigmented lesion with irregular margins, located on anterior region of hard palate. The lesion, complet…

Treatment of post-surgical scars of cheek’s mucosa with Er, Cr: YSGG laser

Background. Bulkiness and unsightly scarring are very common complaints after oral cancer surgical treatment.

Oral health status and periodontitis in Alzheimer's disease patients: A case control Study in a Sicilian rural community

Aim. Dementia is a common disorder among the elderly. Alzheimer’s disease (AD) is the most common cause of dementia. In addition to known risk factors (e.g. age and familiarity) of AD, recently it has been suggested a possible promoting role for chronic inflammatory infective diseases. Periodontal disease (PD) is a frequent chronic multi-bacterial infection involving the tissues supporting the teeth; in addition to promoting inflammation locally, the periodontal pathogens possess mechanisms able to influence the systemic balance of inflammatory mediators. Similarly to other systemic diseases (e.g. cardiovascular disease, diabetes, renal diseases and low birth weight), a possible link has be…
