Abstract
Compared to other conditions found in the necrotizing periodontal diseases group, acute necrotizing ulcerative gingivitis (ANUG) is a definite and specific disease. This illness has a long history that originates from the time of Hippocrates and is also referred to by several synonyms. ANUG occurs less commonly than other oral disorders, even though it is typically not rare. It starts suddenly, advances quickly, and finally results in significant loss of alveolar bone and soft tissue. Viral microorganisms and weakened host defenses have been linked to the etiology and pathophysiology of ANUG. In situations where there is psychological and physiological stress, the incidence of ANUG rises. In developed nations, the incidence of ANUG has declined and, in some cases, gone extinct due to the development of antibiotics and improved nutritional status. However, due to the persistently low nutritional status, the illness continues to be a frequently diagnosed clinical lesion in developing nations. This case report presents the case of a 24-year-old ANUG patient and the sequential treatment of this patient.
