Objectives: The pimary objective of this study was to evaluate the viability of an electronic data logger to record the brushing episodes of patients receiving standardised oral hygiene instructions. The secondary objective was to estimate the compliance of a group of patients diagnosed with chronic periodontal disease with brushing time instructions for the daily use of a powered toothbrush over a 2-month period. Material and methods: 17 modified Philips Jordan Sensiflex 2000 powered toothbrushes (PTBs) were provided to patients (32-67 years) attending for non-surgical management of chronic periodontal disease. The PTBs incorporated an electronic data logger which recorded, for each individual brushing event: the length of time the brush was used (identifying the brushing speed setting); the maximum, minimum and average current during operation; and the time spent charging in between two consecutive brushing events. The patients were given detailed instructions with the PTB and were told to use it for 2 min each morning and 2 min in the evening. The patients returned for non-surgical management over two visits prior to reinforcement of the oral hygiene instructions 1 month after PTB allocation. Subjects were asked to complete a simple brushing diary to record their use of the toothbrush on a daily basis. After 2 months of using the PTBs at home, the brushes and diaries were collected and the data downloaded from the data loggers. Results: Of the 17 data loggers allocated, two recorded no information and two subjects did not return for the follow-up appointments. The data from the remaining 13 data loggers were evaluated for level of compliance. An event of brushing between 120 and 130s was considered to be compliant, one of between 90 and 120 or 130-150s was partially compliant and brushing for < 90 s or > 150 s was recorded as non-compliant. Percentage compliance for all the events (2087 recordings) was 34%, partial- and non-compliance were calculated as: 18%; 48% of events, respectively. Conclusion: This data logger has provided previously unrecorded data on the brushing times for a group of patients using a powered toothbrush at home during non-surgical management of chronic periodontal disease. The data suggested that almost half (48%) of the brushing events recorded by the data loggers were greater than 30 s above or below the instructed brushing time.
