Alveolar bone regeneration in post-extraction socket: a review of materials to postpone dental implant.

Tooth extraction usually involves alveolar bone loss and reduction in height and width of the remaining alveolar socket, owing to the physiological bone resorption. This occurrence may perform an inadequate bone profile, that make difficult orthodontic applications, compromising the functional and aesthetic restoration of dental implants. The present review will provide an update on the biological and clinical profile of materials currently in use and those under investigation, in the recovering of bone margins of edentulous sockets.

Serum anti-p53 antibodies as a diagnostic tumor marker: observations in patients with malignant and premalignant oral cavity lesions.

Aim: To determine whether serum anti-p53 antibody (p53-Abs) positivity in patients with oral carcinoma corresponds with tumor localization, histological grade, stage, and recurrence.

Methods: The study population was divided into three groups: controls; patients with a premalignant lesion; and patients with oral squamous cell carcinoma (SCC). The third group was composed of patients attending outpatient services for pathological diagnosis or for follow-up monitoring only.

Descriptive and topographic anatomy of the accessory infraorbital foramen. Clinical implications in maxillary surgery.

Aim: Study of frequency and position of accessory infraorbital foramen in a large craniological sample.

Methods: A sample of 1 064 skulls from the craniological collection of the Department of Anatomy, Pharmacology and Forensic Medicine of the University of Turin (Italy) was investigated.

Results: Accessory infraorbital foramen was found in 4.

Eagle's syndrome: importance of a corrected diagnosis and adequate surgical treatment.

Elongation of the styloid process and calcification of the stylohyoid ligament as pathological entities described by Eagle are often reported in the literature. The properly called Eagle's syndrome or stylalgia is characterized by a definite symptoms and etiology, that distinguish it from pathologies with partially overlapping symptoms depending on adjacent anatomical structures. A corrected differential diagnosis is paramount for choosing the most adequate treatment.

[Odontogenic tumors. The importance of a correct histopathological diagnosis].

The troubles in the exact diagnosis of odontogenic tumors spring from the poor knowledge of the histological type of the lesion, from mutations in the ectodermal cells of the tumors and from the uncommonness of the pathology. Wrong diagnosis in this field of stomatology often lead to unnecessary surgical resection and could be avoid with better cooperation between surgeon and pathologist.
