“…The status of gingival health of the patients was assessed by recording the presence or absence of bleeding by gentle probing of the gingival pocket at the mesial, buccal, distal and lingual surfaces of all teeth. Instruction of the patients in oral hygiene procedures was delivered by handing out a self-instructional manual in oral hygiene and an oral hygiene kit containing a toothbrush, toothpicks, disclosing tablets, an interdental brush and a lighted mouth mirror for home-use (Glavind et al, 1981), The instruction was given to the patients of the selfexamination group (Se) and the control group (Co) at the 2-week visit, whereas the patients of the delayed instruction group (De) did not receive the instruction before the 6-week visit (Fig, 1), At the 3-month visit, all patients were asked to demonstrate their handling of toothpicks and toothbrush. Scoring of gingival bleeding was made at the start of the study and after 6 weeks and 3 months (Fig, 1), Active treatment phase Information.…”
