426 4- 17-year-old children (89% males) from the Jonglei Province and 50 12- and 15-year-old children from Juba town in Southern Sudan were examined according to WHO criteria (9). The prevalence of calculus and intense gingivitis was high, and highest at ages 8 and 9 years. 8% of 25-year-old children had advanced periodontal disease but this was confined to the anterior mandibular region. Caries prevalence was very low, but much higher in Juba town (36% at both age 12 and age 15 years) than in the Jonglei Province children (4% at 12 years and 8% at 15 years of age). The pastoral, isolated existence of the inhabitants of the Jonglei Province is likely to change with the completion of the Jonglei canal.
对来自琼莱省的426名4至17岁儿童（89%为男性）以及来自苏丹南部朱巴镇的50名12岁和15岁儿童按照世界卫生组织标准进行了检查(9)。牙结石和重度牙龈炎的患病率很高，在8岁和9岁时达到最高。25岁儿童中有8%患有晚期牙周病，但仅限于下颌前部区域。龋齿患病率很低，但朱巴镇的患病率（12岁和15岁时均为36%）比琼莱省儿童（12岁时为4%，15岁时为8%）高得多。随着琼莱运河的建成，琼莱省居民田园式的、与世隔绝的生活方式可能会发生改变。
