The effective and predictable management of gingival overgrowth requires correct diagnosis and consideration of aetiological factors, as discussed in Part 1 (BDJ 2017; 222: 85–91). Initial management should involve cause-related therapy, which may resolve or reduce the lesion. If functional, aesthetic and maintenance complications persist following this phase; further treatment may be required in the form of surgery. This paper discusses management strategies, including management of aetiological factors and surgical techniques.

The patient was also prescribed amlodipine and had type 2 diabetes. With supportive oral hygiene advice, selective extractions and non-surgical treatment the overgrowth is eliminated and periodontal disease stabilised hyperplasia (FIH). To prevent such lesions it has been suggested that complete dentures are replaced at five year intervals.7 Where an area of hyperplasia has developed, initial conservative management involves removing the irritant. This may mean polishing or adjusting the denture flange so that it is well clear of the lesion. Ultimately, the patient is likely to require new dentures, however; it is advantageous to delay this until there has been some resolution of the area. This will aid impression taking and ensure that the prosthe- sis can be optimally extended.
