Are periodontal diseases really silent? A systematic review of their effect on quality of life

AimPeriodontal diseases (PDs) may play an important role in the effect oral health status has on a person's quality of life (QoL). The objective was to investigate the influence of PDs (gingivitis and periodontitis) on oral health-related QoL (OHRQoL) by systematically reviewing the literature. Materials and MethodsStudies using clinical periodontal examinations and validated survey instruments were included. Among 1134 citations initially identified through electronic and hand searching, 37 were eligible and data were extracted from full texts. A vote counting method was used for synthesis of the results. ResultsIncluded studies were published between 2001 and 2014 and revealed considerable heterogeneity in participant selection, clinical assessments, and OHRQoL measures. A significant association between PDs and OHRQoL was reported in 28 studies, of which eight reported increasing impact with greater disease severity or extent. ConclusionsWithin the limits of the available literature, OHRQoL was affected by clinically assessed PDs. There was evidence for increased impairment with greater severity and extent of PDs, and the recognition of the association was increased when full mouth recording protocols were applied.
