在英国武装部队内优先考虑牙周护理资源的需要导致了一种简单的牙周筛查技术的开发和引入，牙周治疗指数（PIT），基于六颗牙齿（所有第一磨牙和上颌右中切牙和下颌左中切牙）的临床评估，使用专门设计的牙周探针（PIT探针）和咬翼射线照相术。本文介绍了该技术的评价。这是通过检查406名受试者，年龄从16岁到64岁，分为四组。所有受试者均接受全口牙周评估，由两名牙周病医生中的一名对他们的前磨牙、第一磨牙和第二磨牙进行标准化咬翼造影。然后将他们分类为牙周健康（PIT 0），牙龈炎但没有超过4 mm的袋状（PIT 1），袋状4 - 5 mm（PIT 2）或6 mm +袋状（PIT 3）。然后，由32名普通牙科医生中的一名对6颗测试牙齿使用PIT技术进行检查和分类，随后查看咬翼片X线照片。对两种类型的检查结果（有或无咬翼片影像学证据）进行了检测，以确定是否存在超过4 mm的骨袋和/或骨丢失的灵敏度和特异性。结果表明，当不使用咬翼作为辅助时，PIT技术在三组中显示出95-100%的特异性，但敏感性较低（36%，52%和59%），第四组中的94%实际上已被转诊进行牙周治疗。当咬翼片被用来作为一个辅助牙周探测，PIT技术显示了100%的特异性，在每组和89 - 100%的敏感性时，筛选口袋和/或骨丢失。得出的结论是，在研究对象中，PIT技术与咬翼片X线摄影结合使用时，提供了简单，快速和可靠的牙周筛查
The need to prioritise resources for periodontal care within the UK Armed Forces has led to the development and introduction of a simple periodontal screening technique, the Periodontal Index for Treatment (PIT), based upon the clinical assessment of six teeth (all first molars and the maxillary right and mandibular left central incisors) with a specially designed periodontal probe (the PIT probe) and the use of bitewing radiography. This paper describes the evaluation of the technique. This was carried out by examining 406 subjects aged from 16 to 64 yr in four groups. All subjects received a full mouth periodontal assessment, performed by one of two periodontists with standardised bitewing radiography of their premolar and first and second molars. They were then categorised as periodontally healthy (PIT 0), with gingivitis but no pocketing exceeding 4 mm (PIT 1), with pocketing 4‐5 mm (PIT 2), or with 6 mm + pocketing (PIT 3). The subjects were then examined and categorised by one of 32 General Dental Practitioners using the PIT technique upon the six test teeth and subsequently viewing the bitewing radiographs. The results of the two types of examination, with and without bitewing radiographic evidence, were tested for sensitivity and specificity to detect pocketing in excess of 4 mm and/or bone loss. The results showed that, when used without bitewings as an adjunct, the PIT technique showed a specificity of 95–100% but a low sensitivity in three groups (36%, 52% and 59%) and of 94% in the fourth group who had in fact been referred for periodontal treatment. When bitewing radiographs were used as an adjunct to periodontal probing, the PIT technique showed a specificity of 100% in each group and a sensitivity of 89 100% when screening for pockets and/or bone loss. It was concluded that, in the subjects studied, the PIT technique when used in conjunction with bitewing radiography provided simple, rapid and reliable periodontal screening
