The Periodontal Treatment Needs System (PTNS) was used to classify needs of 102 patients, 97 males and five females, at the VAMC Dental Service. The PTNS is based on the presence or absence of plaque, calculus or overhangs, inflammation and pocket depth. In addition, need for restorative and prosthetic care was added to the PTNS based on dentists' diagnosis. All classification was done by quadrant. All subjects required dental hygiene or periodontal care; 45% of the subjects need restorative treatment, prosthetic treatment, or both. Differences in numbers of patients requiring each type of treatment were highly significant. Multiple regression showed that age was positively related to type of treatment needed, with a significant difference in dental hygiene or periodontal needs by quadrant. The results of this study show greater need for dental hygiene and periodontal treatment than for dental treatment in these patients.
牙周治疗需求系统（PTNS）用于对退伍军人事务部牙科服务处的102名患者（97名男性和5名女性）的需求进行分类。PTNS基于菌斑、牙石或悬突的存在与否、炎症和牙周袋深度。此外，根据牙医的诊断，将修复和假牙护理需求添加到PTNS中。所有分类均按象限进行。所有受试者都需要口腔卫生或牙周护理；45%的受试者需要修复治疗、假牙治疗或两者都需要。需要每种治疗类型的患者数量差异非常显著。多元回归显示，年龄与所需治疗类型呈正相关，各象限在口腔卫生或牙周需求方面存在显著差异。这项研究的结果表明，这些患者对口腔卫生和牙周治疗的需求比对牙科治疗的需求更大。
