“…Sjogren et al (2010) indicated that a single oral health education of the caregivers yearly was insufficient to improve the oral health status of the residents after 1.5 yrs. Possible reasons for the lack of a significant impact of the caregivers' training on the oral health status of the elderly residents may include relatively good oral health status of residents at baseline (MacEntee et al, 2007), less sensitive measurement scales for the oral health assessments (Gammack and Pulisetty, 2009), too small a sample size to detect a 20% difference (MacEntee et al, 2007), short presentation without adequate training or theory of improved oral health care (Gammack and Pulisetty, 2009), insufficient time due to competing personal care duties (Gammack and Pulisetty, 2009;Reed et al, 2006;Simons et al, 2000), inadequate staffing intensity at facility (Gammack and Pulisetty, 2009;Reed et al, 2006;Simons et al, 2000), insufficient supplies for oral health care (Coleman, 2005), the Hawthorne effect on the facilities and staff (MacEntee et al, 2007), and a relatively high turnover of staff at the facility between the pre and post training assessments (Simons et al, 2000). Multiple oral health education sessions augmented the oral health knowledge and practical oral hygiene procedures of the caregivers (Reed et al, 2006), but some facilities hesitated to provide the extra time for staff training due to workload (Simons et al, 2000).…”
