Since entering the elderly, the body has a deterioration of physical performance in many systems including the brain system. This leads to cognitive impairment. In the past, there were some studies in many countries that have found a correlation of oral health status with cognitive impairment. The elderly with cognitive impairment had worse oral status than those without the condition. This study was a cross-sectional study that aimed to study the oral health status in the elderly with cognitive impairment. The sample group was people aged at least 60 years living in Ban Fang District. Khon Kaen Province. They passed the screening for cognitive impairment. The brain function assessment questionnaire called MMSE Thai-2002 and MoCA were translated into Thai language and applied in this study. Data were collected through questionnaires and oral health status examinations. The examination has consisted of checking in periodontal probing depth, plaque accumulation, Clinical attachment loss (CAL), teeth decay, and teeth loss patterns according to Eichner's index assessment. The result revealed that there were 129 (36.0%). Elderly samples participating in this study with an average age was 66.7 years (±3.7), 66.7% of the sample were women. They had the greatest teeth loss proportion (54.3%) in the B pattern according to Eichner's index. The mean of periodontal probing depth was 2.1 (±0.7), 43.4% had a mean of Clinical attachment loss (CAL) at 3-4 mm. The mean CAL level was 4.3 mm (±1.6), mean of teeth in the oral cavity was 17.8 teeth per person (±7.9). Mean DMFT was 13.1 teeth per person (±8.5), 26.4% had at least 4 pairs posterior occlusion support and 6.1.8% had a mean of cleanliness was at the medium. In conclusion, the oral health status in elderly who has cognitive impairment was shown to remind us for the importance of supporting prevention and promotion program.
