Primary Outcome Measures

Name	Time	Method
The sensitivity of the CAT (COPD Assessment Test) score to predict poor tooth status as measured by the DMFT (Decay-missing-filled index) index and PSI (Pneumonia severity index) score is examined. The data is collected during the outpatient presentation at the dentist. This marks the time of measuring the Primary endpoint. The study for the patient ends the same day the patients are approached. After successful data collection, the evaluation begins. The area under a prepared ROC (Receiver Operating Characteristic) curve will be analyzed to achieve a clinically useful recommendation in terms of sensitivity and specificity in using this tool. In addition, the positive predictive and negative predictive value is determined and the optimal cut-off value of the CAT score is calculated and discussed using Youden's index.

Secondary Outcome Measures

Name	Time	Method
An analysis of the OHIP 14 questionnaire (Oral Health Impact Profile) will be conducted to determine if there is a decreased oral health associated quality of life in the panel examined in this study. This questionnaire will also be evaluated the same day the patients present themselves in the outpatient dental clinic, therefore marks the time of measuring the secondary endpoint. After successful data collection the questionnaires will be evaluated. For this purpose, the collected data is set in relation to existing norm values ??and interpreted.
