Any pathology begins at the cellular level representing morphological or functional changes, so it is very important the use of techniques for observing such changes and lead to an early diagnosis and treatment. Oral exfoliative cytology is defined as the study and interpretation of the character of the cells that are shed naturally or artificially, from the oral mucosa. Consists microscopically observe the morphology of the surface epithelial cells after collection, fixation and staining. It is a simple, non-invasive, relatively painless and well accepted by patients. Made a research is descriptive and transactional design field with quantitative approach, the sample consisted of teachers who work in the Faculty of Dentistry at the University of Los Andes that met the inclusion criteria, we used a survey to collect data with closed answers questions directed to teachers sampled, which addressed the oral cytology used by them and their students as a means of diagnosis of oral lesions. It was observed that oral cytology is used with very low frequency as diagnosed technique, as is little encouraged by teachers, and in some cases it is not known .. To conclude the literature indicates that oral cytology is an important means of early diagnosis of oral premalignant lesions, because this is important to apply as a means of diagnosis in the Faculty of Dentistry at the University of Los Andes.

Aging, scars and a number of defects that appear on the face can affect the patient physically and psychologically. Currently, the use of orofacial filling biomaterials has become common. The pharmaceutical industry proposes new products every year, however, the search for the ideal biomaterial still continues. Chitosan is a natural biocompatible and biodegradable biopolymer that exhibits regenerative properties. It can be considered a therapeutic alternative for aging and tissue loss. It was proposed to analyze the injectable chitosan gel as a cutaneous biostimulator in Sprague dawley rats. An experimental study was carried out in 43 adult male rats divided into: experimental group A (n = 20 animals), control group B (n = 20 animals) and control / control group C (n = 3 animals). The material was infiltrated into the back of each animal via the intradermal route. Group A was infiltrated with 0.05 ml of chitosan gel, group B with 0.05 ml of hyaluronic acid and group C did not receive any material. Follow-up was done, at the fourth and eighth week, 10 animals from groups A and B and 1 from group C were sacrificed for taking histopathological samples. It was concluded that the injectable chitosan gel does not generate alterations in the behavior of the animals and produces the formation of a nodule in the infiltrated area. On microscopic examination, it behaves as a damaging agent that produces a chronic exacerbated inflammatory response and a foreign body granuloma-like reaction.
