3.1 | Periodontitis and severity of CHD
The severity of the CHD was determined based on the number of coronaries affected and the CCS scores for angina pectoris. No significant associations between the periodontal status according CDC and these internal conditions could be determined (Table 1). If instead the criteria of the CDC the new classification of periodontitis or the values for PESA and PISA were used to assess the severity of periodontitis, no significance could be achieved either (data not shown)
