AIM
To determine the pH of pus collected from periapical abscesses.
METHODOLOGY
Forty patients (Male = 17/Female = 23) between the ages 17 and 37 years, each with a periapical abscess and with no relevant medical history, were recruited. All the participants had moderate-to-severe pain on percussion accompanied by localized or generalized swelling. At least 1 mL of pus was aspirated from each participant using a No 20 gauge needle. A pH meter was used to define the pH of the pus immediately following aspiration.
RESULT
The mean pH of pus from the periapical abscesses of patients was 6.68 +/- 0.324 with a range between 6.0 and 7.3. There was no statistically significant difference in pH by gender or age.
CONCLUSION
The mean pH of pus from periapical abscesses was generally acidic, but some samples (two female and three male) were neutral and some samples (four female and one male) were alkaline.
目的
测定从根尖周脓肿采集的脓液的pH值。
方法
招募了40名年龄在17至37岁之间的患者（男性17名/女性23名），每名患者均患有根尖周脓肿且无相关病史。所有参与者在叩诊时有中度至重度疼痛，并伴有局部或全身性肿胀。使用20号针头从每名参与者身上抽取至少1 mL的脓液。抽取脓液后立即使用pH计测定脓液的pH值。
结果
患者根尖周脓肿脓液的平均pH值为6.68 +/- 0.324，范围在6.0至7.3之间。pH值在性别或年龄方面无统计学显著差异。
结论
根尖周脓肿脓液的平均pH值通常呈酸性，但一些样本（两名女性和三名男性）呈中性，一些样本（四名女性和一名男性）呈碱性。
