A B.P.E reading of 1 suggests what type of treatment?

A B.P.E. (Basic Periodontal Examination) reading of 1 indicates that there are no pockets probing deeper than 3mm, with no bleeding on probing, which suggests that the periodontal health is generally good. In this context, the primary focus should be on maintaining oral hygiene and preventing any potential escalation of periodontal issues.

The correct answer relates to providing Oral Hygiene Instructions (OHI) only. This approach emphasizes education on maintaining proper oral health practices without the need for more intensive interventions like plaque removal or scaling and debridement, which would be considered when there is a more advanced periodontal condition indicated by higher B.P.E. scores. By focusing solely on the delivery of OHI, it encourages the patient to engage in daily hygiene practices to maintain their dental health based on the good status reflected in the B.P.E. reading.

Other options suggest additional treatments that are unnecessary at this stage given the indicated health status.
