Included dental organs are associated with various jaws pathologies, among the most frequent are cysts, which are benign lesions that develop around the crowns from permanent teeth. The aim of this research is to propose a therapeutic algorithm and a treatment plan combined with two known techniques, in addition to describe clinical and radiographic findings and conservative therapeutic management. For this, gender and clinical diagnosis data were obtained from a series of 3 cases of dentigerous cyst, in which clinical, histological, radiographic characteristics and treatments used were described. In each case conservative surgical treatment was given accompanied by gauze soaked in nitrofurantoin. Because dentigerous cysts are the most common pathology associated with included dental organs, which can be detected in routine radiographic examinations, this must be corroborated with the histopathological study, allowing less invasive techniques, this work is based on a therapeutic algorithm and combined treatment plan, not only in children but also in adults, regardless of their size.
