[Comparative phorogrammetric studies on a periodontal index].
Reproducibile results are difficult to obtain with subjectively recorded periodontal indexes. The information acquired via such indexes therefore may be called into question. Inflammation of the gingiva was induced in 15 subjects. The degree of gingival swelling was determined via monophotogrammetry; the degree of inflammation, with the PMA index which emphasizes the symptom "swelling". The results were compared and discussed. It is highly probable that the PMA index is subjectively overrated.
