As with all indices which impose numerical scales on a biological process, there are limitations with CPITN which must be identified and recognised. The limitations are due to the index being used for purposes for which it was not originally designed and recent advances in understanding which question the underlying assumptions of the index. Whilst questioning whether these limitations are sufficient to abandon the CPITN in favour of a new index, suggestions are made for modifications to the existing system. These include, the recording of each of the clinical indicators separately, as well as including the measurement of total loss of attachment. In addition an extension of the treatment need scale from four to five points is suggested.
与所有对生物过程施加数值尺度的指数一样，社区牙周指数（CPITN）存在一些必须加以识别和认识的局限性。这些局限性是由于该指数被用于其最初并非设计的目的，以及在理解方面的最新进展对该指数的基本假设提出了质疑。在质疑这些局限性是否足以放弃CPITN而支持新指数的同时，还针对现有系统提出了修改建议。这些建议包括分别记录每个临床指标，以及纳入附着丧失总量的测量。此外，建议将治疗需求量表从四点扩展到五点。
