Universal adhesives applied to deep dentin with different bonding treatments.

Unlabelled: Eighth-generation adhesives may be applied with total etch, selective-etch or self-conditioning, and serve as primers for non-dental substrates.

Aim: To determine the bonding characteristics of universal adhesives applied to the deep pulp wall with different strategies, by means of shear bond strength and laser microscopy.

Materials And Method: Cavities 4 mm deep and maximum width were carved in 36 extracted molars.

Microscopic Study of Surface Microtopographic Characteristics of Dental Implants.

Objective: To determine and compare the micro topographic characteristics of dental implants submitted to different surface treatments, using scanning electron microscopy (SEM).

Materials And Methods: Implants were divided into 7 groups of 3 specimens each, according to the surface treatment used: group 1: Osseotite, BIOMET 3i; group 2: SLA surface, Institut Straumann AG; group 3: Oxalife surface, Tree-Oss implant; group 4: B&W implant surface; group 5: Q-implant surface; group 6: ML implant surface; group 7: RBM surface, Rosterdent implant. The surfaces were examined under SEM (Carl Zeiss FE-SEM-SIGMA).

[Hypogastric artery. Anatomic study and ligation].

This anatomical study has been done to determine the different segments of the hypogastric artery with it's relationships and the place in which it should be surgically ligated in emergency situations, particularly gynecologic and obstetric.

[Recurrent laryngeal nerve and inferior thyroid artery. Anatomo-surgical considerations].

Among the diverse complications of thyroidectomy, it is mostly the cordial sequels from the recurrent laryngeal nerve damage. This is why anatomical and surgical considerations are made upon the vulnerable areas of this nerve and the circumstances in which it is damaged. The relationship between the recurrent laryngeal nerve and the inferior thyroid artery, location most frequently injured, was investigated on 55 adult formulated cadavers.
