Bases para Interpretação de Exames Laboratoriais na Prática Odontológica Bases for Interpretation of Laboratory Tests in Dental Practice

Laboratory tests are important in defining the diagnosis, when this cannot be explained by data from clinical history and physical examination. Dentists must request exams because some systemic problems may complicate and alter the prognosis or even contraindicate performing surgeries or invasive procedures. This topic is relevant because a large percentage of graduates in dentistry have difficulty ordering and interpretation of laboratory tests. This study aims to review basic concepts of interpretation and criteria for requesting laboratory tests such as complete blood count and Coagulation. This study was developed through documentary analysis of bibliographic production obtained through the database: Virtual Health Library (VHL), Brazilian Digital Library of Theses and Dissertations (BDTD) and CAPES Journals. We conclude that the laboratory tests, when properly indicated, collaborate to decide the correct procedure. For the values found before, being above or below the reference values, when interpreting them correctly, the professional can prevent situations of secondary infections, poor wound healing, bleeding and complications during dental treatment. Thus, professional that interpret laboratory tests correctly can offer greater safety to the patient.
