Background: The most important aetiological factor of periodontal disease is plaque deposition aroundgingival margin. The aim of the study was to investigate the negative changes in periodontal health(increase in pocket depth) of first molars in fixed orthodontic treatment and to discuss the availableoptions to avoid it. Methods: Group A (6 month of treatment) comprised of 45 patients, compared toGroup B (12 month of treatment) comprised of 45 patients. Initial pocket depth of first molars checkedbefore placement of molar bands in both groups of patients, then for Group A patients pocket depthevaluated after 6 month of treatment and for Group B patients pocket depth evaluated after 12 month oftreatment period. Results: In patients with 6 months of treatment the pocket depth of molars mostly fallsbetween 1.5 and 2.0 mm. In some severe cases it exceeded 3 mm. In patients at 12 months of treatmentpocket depth was greater than 6 month group and it mostly fell in the range of 2.0–2.5 mm. Conclusion:Increase in pocket depth showed that plaque deposition leads to periodontal destruction around molarbands. Patient motivation to maintain oral hygiene and regular scaling will minimise hazardous effects.Keywords: Pocket depth, Gingivitis, Oral hygiene, fixed orthodontics
