A 19-year-old male patient consulted a dentist about gingival pain and bleeding when eating and brushing his teeth. Objectively: anterior maxillary and mandibular teeth are overcrowded, there is hyperemia, cyanosis and overgrowth of gingival papillae up to 1/3 of the crown height. The soft plaque is present. The gums bleed when touched with a tool. What is the most likely diagnosis?
