High Resolution Photographs of Maxillary gross quadrant grades [(GQG) 0–4 and MRONJ]. (A) GQG scores are at the top of each HR photograph. GQG0: Normal Maxilla. GQG1 (slight): Discrete lesion containing impacted food and hair at lingual aspect of interdental region of M2 M3 (arrow); FILP lesion occupies less than half of the lingual gingival margin of M2. GQG2 (mild): Lesion occupies two-thirds of lingual gingival margin of M2 and one-third of M3 (arrow), but does not extend toward midline. GQG3 (moderate): Lesion occupies complete lingual-gingival margin of M2 and two-thirds of M3, and extends almost halfway to the midline (arrows). GQG4 (severe): Lesion in left maxilla occupies complete lingual-gingival margin of M1–M3 and extends more than halfway to midline (arrows). MRONJ: A lesion of GQG = 3–4 (arrows) with exposed alveolar bone (*). (B) Total maxillary area (Tt.Mx.Ar) (black lines).
