Abstract
Fixed or removable orthodontic appliances impede the maintenance of oral hygiene and result in plaque accumulation. Many studies have evaluated the effects of fixed orthodontic appliances on microbial flora and periodontal status, but only a few have evaluated the method of ligation as an additional factor. AIMS AND OBJECTIVES: To determine the amount of microbial colonization with different elastomeric ligation techniques. MATERIALS AND METHODS: Subjects for this study was selected on the basis of good oral hygiene. Amount of microbial colonization was evaluated from both right and the left sides of the maxillary dental arch at day 1 that is (after receiving through oral prophylaxis) and then the arch wire ligated with split mouth technique using Super Slick ties (TP Orthodontics) and Dumbell ligatures (Leone) on right side & Aelastixs- Quick stick ties- Angulated ties (3M Unitek) and Aelastixs- Easy to fit Ties (3M Unitek) on left side. Elastomeric ligatures were removed from the patients' mouth after a period of 7 days and sent for culture of the aerobic and anaerobic bacterial colonies. The amount of microbial colonies was then compared using stereomicroscope. RESULTS: The current study revealed that the teeth ligated with elastomeric rings exhibited greater number of aerobic as well as anaerobic microorganisms and the difference was found to statistically significant.
