Diagnosis of Periodontal DiseasesDiagnosis of Periodontal Diseases

The diagnosis of periodontal disease is a process The diagnosis of periodontal disease is a process that involves observation and measurement of that involves observation and measurement of numerous factors and then combining one's numerous factors and then combining one's findings into a summary statement of the findings into a summary statement of the patient's oral disease status. patient's oral disease status.
