A STUDY ON THE HYDROGEN ION CONCENTRATION OF PUS IN THE SUPPURATIVE ORAL DISEASES

화농성구강질환에 있어서 농즙의 수소이온 농도에 관한 연구

Author has made the studies on the pH of pus in the 53 suppurative disesed patients who had admitted to department of ora surgery, Infirmary of Schoo of Dentistry, Seoul National University. The results were obtained as follows; 1. The average pH of pus in the patients with suppurative oral diseases was 6.46 and the pH of pus was ranging 5.0 to 7.2. 2. The pH value of pus was not significant between the males(pH: 6.58) and females (pH: 6.40). 3. The pH vaule of pus in patients treated by antibiotics trend to slightly alkaline than that of untreated patients. 4.The pH vaule of pus in the pericoronitis, periodontal abscess and other localized oral infections were slightly alkaline than buccal abscess and osteomyelitis, and acute suppurative diseases of jaws was more acid than chronic diseases. In general, it was seemed the early stages of inflammation was alkaline, and the later stages was acid.
