Periodontitis is common in the elderly and may become more common in Alzheimer’s disease because of a reduced ability to take care of oral hygiene as the disease progresses. Elevated antibodies to periodontal bacteria are associated with an increased systemic pro-inflammatory state. Elsewhere raised serum pro-inflammatory cytokines have been associated with an increased rate of cognitive decline in Alzheimer’s disease. We hypothesized that periodontitis would be associated with increased dementia severity and a more rapid cognitive decline in Alzheimer’s disease. We aimed to determine if periodontitis in Alzheimer’s disease is associated with both increased dementia severity and cognitive decline, and an increased systemic pro inflammatory state. In a six month observational cohort study 60 community dwelling participants with mild to moderate Alzheimer’s Disease were cognitively assessed and a blood sample taken for systemic inflammatory markers. Dental health was assessed by a dental hygienist, blind to cognitive outcomes. All assessments were repeated at six months. The presence of periodontitis at baseline was not related to baseline cognitive state but was associated with a six fold increase in the rate of cognitive decline as assessed by the ADAS-cog over a six month follow up period. Periodontitis at baseline was associated with a relative increase in the pro-inflammatory state over the six month follow up period. Our data showed that periodontitis is associated with an increase in cognitive decline in Alzheimer’s Disease, independent to baseline cognitive state, which may be mediated through effects on systemic inflammation.

We investigated awareness in dental hygienists of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in patients with osteoporosis and cancer and assessed the situation in systemic history investigations to broaden the scope of the dental hygienists' BRONJ awareness as a basis for contributing to preventing this disease. The study was carried out through a survey; 217 dental hygienists responded to the survey. They worked at 12 university and general hospitals, 10 dental hospitals and 35 dental clinics, for a total of 57 institutions in Seoul. The survey consisted of 37 questions: general characteristics (J Oral Maxillofac Surg 65: 2007; 369), systemic history investigations (Ruggiero et al. J Oral Maxillofac Surg 62: 2004; 527) and awareness of BRONJ (Park et al. J Korean Dent Assoc 49: 2011; 389). Among them, 79.7% were aware of BRONJ. Recognition was highest among those from 25 to 35 years old (P < 0.05). In terms of work experience, those with 5-10 years experience showed the highest awareness (P < 0.05). In terms of institutions type, dental clinics showed lower awareness than general and dental hospitals (P < 0.05). It was found that 55.3% of the dental hygienists had been educated about BRONJ. Those aged 25-35 years were the most educated. In terms of institutions, dental clinic staff were the least educated. The degree of understanding about BRONJ was analysed with the average score of 6.14 points. According to these results, dental hygienists working in university hospitals and general hospitals had more opportunity to receive training than those working in dental clinics. Thus, it is considered that the development of professional training programs about BRONJ for all dental hygienists is necessary.

The British Columbia Ministry of Health in Canada approved a new registration category for dental hygienists in 2012. This category included four abilities that registrants were required to demonstrate at a 4th-year baccalaureate degree level.

In 2015, adults aged ≥65 years with diagnosed diabetes were more likely than adults without diagnosed diabetes to report seeing general doctors (92.3% compared with 86.7%); eye doctors (66.9% compared with 56.6%); physician specialists (51.5% compared with 45.5%); foot doctors (29.9% compared with 13.0%) and mental health professionals (6.3% compared with 4.5%) in the past 12 months. Those with diabetes were less likely than those without diabetes to report seeing a dentist or dental hygienist in the past 12 months (54.5% compared with 65.0%).

Dental hygienists are important members of the oral health care team, providing preventive and prophylactic services and oral health education. However, scope-of-practice parameters in some states limit their ability to provide needed services effectively. In 2001 we developed the Dental Hygiene Professional Practice Index, a numerical tool to measure the state-level professional practice environment for dental hygienists. We used the index to score state-level scopes of practice in all fifty states and the District of Columbia in 2001 and 2014. The mean composite score on the index increased from 43.5 in 2001 to 57.6 in 2014, on a 100-point scale. We also analyzed the association of each state’s composite score with an oral health outcome: tooth extractions among the adult population because of decay or disease. After we controlled for individual- and state-level factors, we found in multilevel modeling that more autonomous dental hygienist scope of practice had a positive and significant association with population oral health in both 2001 and 2014.

Increased levels of anxiety may affect a patient’s receptiveness to treatment, health care information and behaviour modification. This study was undertaken to assess pre-treatment anxiety in a dental hygiene recall population maintaining a schedule of regular preventive care appointments.

Despite expansion of the scope of practice and clinical responsibilities of dental hygienists since 1945, the degrees granted for dental hygiene remain the same. The majority of dental hygienists complete 4 or even 5 years of college to receive an associate’s degree while a few earn a baccalaureate degree. The aim of this study was to determine whether an associate’s degree appropriately matches the current level of dental hygiene education.

Dental hygiene students' performance in oral radiology courses may give an early indication of their readiness prior to taking the National Board Dental Hygiene Examination (NBDHE). The aim of this study was to determine the relationship between dental hygiene students' performance in an oral radiology lecture course and their performance on the NBDHE. Data were collected for all 117 dental hygiene students at Texas A&M University College of Dentistry from 2006 to 2009 who took the NBDHE during their second year of the program. Their final grades and scores on three written section examinations in an oral radiology course taken in their first year were compared with their overall NBDHE scores and raw scores on the oral radiology and case study sections. Moderate correlations (0.3

There is a scarcity of studies on Canadian baccalaureate dental hygienists. As discussions about baccalaureate education for dental hygiene continue on a national level, examining outcomes of earning a dental hygiene degree is paramount.
