Alzheimer\'s disease (AD) is the most common acquired cerebral degeneration and the main cause of dementia in Western countries. Its physiopathology involves neuronal abnormalities and an inflammatory process. Dental infections are frequent in these patients, and important causes of pain and chronic inflammation. The objectives of this research were to evaluate the dental characteristics and orofacial pain of patients with mild AD compared to controls, and to verify cognitive, functional and emotional aspects after the treatment of present oral infections. Twenty-nine patients (29) and 30 controls were evaluated, and the patients were treated and reevaluated in two moments (after one month and after six months). The following instruments were used: clinical questionnaire (Clinical Questionnaire of Orofacial Pain); Research Diagnostic Criteria for Temporomandibular Disorders; McGill Pain Questionnaire; Oral Health Impact Profile (OHIP); periodontal clinical evaluation; DMFT; Plaque index of O´Leary; Mini-Mental State Exam; functional scale of Pfeffer. In the study group, there was a higher prevalence of orofacial pain (20.7%, P<0.001), articular abnormalities at temporomandibular joints (P<0.05) and periodontal infections (P=0,002). After the treatment, the pain reduced (P=0,014), as well as mandibular limitations (P=0.011) and periodontal indexes (P<0.05), and there was an improvement in quality of life (P=0.009), functional index (P<0.001) and cognition (P=0.048). In conclusion, orofacial pain and periodontal infections were more common in patients with mild AD than in healthy subjects and their treatment resulted in better functionality of them (AU)
