Summary: The Hiroshima University-Dental Behavioral Inventory (HU-DBI) has
been shown to be useful for understanding patients' perceptions and oral health
behavior in many countries. The HU-DBI comprises 20 items dealing mainly with
toothbrushing behavior. On the other hand, the Oral Rating Index (ORI) is a
simple method to screen periodontal health and classify people into five levels. It
has been shown that ORI scores were significantly associated with HU-DBI
scores. Recently, we have developed a new computer program named ‘Picar’
regarding the ability to evaluate periodontal health status using ORI criteria. This
software can be used under two conditions: a test or calibration tool toward
researchers group at the same time using LCD projector, or individuals sit in
front of the computer and run the program, to improve their diagnosis ability. It
takes 5 minutes. Using ‘Picar’, the examinees are classified into 19 levels like
the ranking system of ‘Karate-Do’. Rank is used to keep examinees motivated or
to give them a sense of progression. To use the computer is time saving and
more flexibility. Tests can be taken independently of time or place and scored
immediately with instant feedback. We will demonstrate both ‘Picar’ as a
computer training soft for periodontal health and HU-DBI as an appropriate
behavioral test for gingival self-care levels, at the Workshop-seminar for the
Second International Conference on Tropical Oral Health.

(0)
whether it is good (+) or bad (-).

give "+1" if it is not so good. For "-" diagnosis, give "-2" if it is obviously

[Note] Ignore the extent of dental caries/filled teeth as it is not related to the ORI judging.
1) The ORI score is judged from gingival status and the presence and extent of local
irritants with reference to this standard color photo.
( Gingiva：Calculus：Plaque = 5 ： 3 ： 2 )
2) This index is based upon examination of four areas: the facial surfaces of the anterior
teeth and the lingual surfaces of the right posterior teeth in the mandible and maxilla.
3) When in doubt, the examiner should assign the lesser score.
4) Each assessment should be done within ten seconds.
