“…Drug‐induced gingival overgrowth prevalence and severity are assessed through full‐mouth alginate impressions (Seymour et al , 1985). Prevalence in transplant recipients on ciclosporin is high (20–76%) (Greenberg et al , 2008; Shiboski et al , 2009b; Cota et al , 2010; Paixão et al , 2011), markedly lower in the absence of gingivitis (Aimetti et al , 2005, 2008; Kara et al , 2007). Some thus attribute a causative role to dental plaque, and others even consider DIGO a risk factor for dental caries development (Doufexi et al , 2005; Nakib and Ashrafi, 2011), but observational studies fail to support such hypotheses, showing no significant differences between transplant patients with DIGO and controls in parameters such as oral hygiene, gingivitis, and caries (al‐Sarheed et al , 2000; Sheehy et al , 2000; al Nowaiser et al , 2004).…”
