Abstract: People suffering from Alzheimer’s disease suffer from cognitive declines which deteriorate their general and oral health. We frequently observe dental cavities, periodontal disease and tooth loss among these people. In that respect, we wanted to establish a health and oral evolutionary curve throughout Alzheimer’s disease. To that end, we conducted a prospective observational study that includes a transverse and longitudinal component. The participants had to have Alzheimer’s disease at different stages, have teeth and live in the province of Quebec. Combative, bedridden people, and those who were diagnosed with bacterial endocarditis or who had heart valve prostheses were excluded from this research. The data corresponding to the variable responses (number of visible and missing teeth, obturations, cavities, retained dental roots and loose teeth, plaque index and gingival bleeding) and explanatory variables (age, gender, education level, resulting score to the Folstein Mini-Mental State Examination, co-morbid conditions, quantity of saliva and the use of dental care) have been provided through a medical examination form. We recruited participants (n = 46) from six Quebec health facilities between May 2016 and October 2017. This study showed that as Alzheimer’s disease progresses, dental plaque (p = 0,05) and gingival bleeding (p = 0,01) increase and the number of teeth (p < 0,0001) and fillings (p = 0,04) decreases. Also, the number of cavities, retained dental roots and loose teeth, seem to increase with the progression of the disease. The probability of having a cavity drastically increases as the cognitive decline progresses (p = 0,023). In conclusion, oral health deteriorates with the development of Alzheimer’s disease, and this from the moderate stage of the disease.
