The Periodontal Treatment Need System (PTNS) was applied to a group of young Israeli adults, 18-25 years of age, to test the system in the field. A total of 830 persons were examined. Their periodontal treatment needs were assessed. One of the aspects investigated was that of treatment needs according to distribution by sex. Only 2.7% of young adults studied were free of plaque, calculus and gingival inflammation. All the rest (97.3%) needed some kind of periodontal treatment. The time required for treatment needed was also calculated. It was found that on the average 2.4 h per person would be required to deliver the periodontal treatment needs of the group. A close association between sex and PTNS was established in this study.
牙周治疗需求系统（PTNS）应用于一组18至25岁的以色列年轻成年人，以在实际环境中测试该系统。共检查了830人。评估了他们的牙周治疗需求。所调查的一个方面是按性别分布的治疗需求。在所研究的年轻成年人中，只有2.7%没有牙菌斑、牙石和牙龈炎症。其余所有人（97.3%）都需要某种牙周治疗。还计算了所需的治疗时间。结果发现，平均每人需要2.4小时来满足该组的牙周治疗需求。本研究确立了性别与PTNS之间的密切关联。
