Necrotising periodontal diseases

Figure 38.3 (a–c) Following the acute phase, the symptoms have settled down in this 27-year-old male smoker, but there is evidence of: (i) interdental necrosis and punched out papillae in the maxillary and mandibular anterior regions; (ii) gross deposits of subgingival calculus which are now located supragingivally due to apical migration of the gingivae; and (iii) detachment of the buccal gingiva from the mandibular incisors, indicating clinical attachment loss has occurred (i.e. destruction of the periodontal ligament. This indicates a transition from NUG to NUP.

Following the 1999 International Workshop for the Classification of Periodontal Diseases and Conditions, it was recommended that necrotising ulcerative gingivitis (NUG) and necrotising ulcerative periodontitis (NUP) should be collectively call/>
