A Short-Term Evaluation of Periodontal Effects of Different Orthodontic Retainer Combinations.
Journal Title: Journal of Medical and Dental Science Research (Quest Journals JMDSR) - Year 2017, Vol 4, Issue 9
Abstract
This study was performed to evaluate the short-term periodontal effects of two combinations of upper removable and lower fixed retainers. Twenty patients who completed orthodontic treatment with fixed appliances were divided into two groups (A and B) of 10 patients each. Group A patients were given an upper wrap-around retainer and a lower bonded canine to canine retainer. Group B patients were given an upper vacuum formed and a lower bonded canine to canine retainer. Periodontal examination including pocket depth (PD), bleeding on probing (BOP) and plaque index (PI) was performed at insertion (T1) and 4 weeks after insertion (T2) of the retainers. PD and BOP scores were obtained at six sites per tooth. A significant increase of PI and BOP on mandibular lingual surfaces was recorded, whereas there were no changes for other parameters on both labial and palatal sites in the maxillary arch and labial sites in the mandibular arch in both groups. In the short term, both plaque accumulation as well as bleeding on probing increased in the areas of mouth where fixed lingual retainer was bonded but there was no increase in the pocket depth. Both Hawley type and vacuum formed retainers were similar in having no significant detrimental effect on periodontal parameters at all sites.
