The present study was a clinical controlled trial to assess the effectiveness of Brief Lifestyle Change plus
Dental Care program to decrease glycemic level and improve periodontal status in type 2 diabetes patients. The present
study was conducted in Diabetes clinic, Public Health Center 54 from February 2018 to February 2019. Diabetes
patients were divided to 96 patients for the intervention and 96 patients for the control groups. The intervention group
received group education for lifestyle modification, individual oral hygiene instruction, and lifestyle counseling by
motivational interviewing at baseline and the 6th month and received booster education every visit by viewing
educational video. Routine program was provided to the control group. At baseline, the 6th month and 1 year follow up,
glycemic level and periodontal status were assessed from the participants. Data were analyzed by descriptive statistic,
t-test, Chi-square test, Fisher’s exact test, Mann-Whitney U test, and Repeated measure ANOVA. The intervention
group had significantly lower glycemic level and periodontal status than the control group at the 6 month and 1 year
followed up. Brief-LCDC program which incorporated lifestyle modification and oral health care had efficacy to decrease
