A study was undertaken to test the hypothesis that clinical photographic records can be used to motivate oral hygiene performance in mentally handicapped adults. Plaque reduction over the period of the study was shown to be higher in the test group than the control group but differences between the test and control groups were not statistically significant. The small numbers involved (29) and the difficulties in matching subjects may have mitigated against demonstrating a statistically significant difference between the two groups. All participants demonstrated high levels of toothbrushing ability during the practical aspects of the study but this was not maintained through daily oral hygiene practices in the majority of subjects.
开展了一项研究，以检验临床摄影记录可用于激励成年智障人士口腔卫生表现这一假设。研究期间，试验组的牙菌斑减少情况高于对照组，但试验组与对照组之间的差异无统计学意义。涉及的人数较少（29人）以及匹配受试者的困难可能不利于显示两组之间的统计学显著差异。在研究的实践环节中，所有参与者都表现出较高的刷牙能力，但在大多数受试者的日常口腔卫生实践中，这种能力并未得到保持。
