One hundred orthodontic patients, 60 females and 40 males, their mean age (l7± 1.5 y) and 40 patients who are going to have orthodontic treatment, 24 females and 16 males with mean age (16.7± 0.7 y) were selected. For (very participant the following parameters were recorded: 1- Quigley and Hein plaque index.2- Papillary bleeding index .3- Probing pocket depth. 4 - Attachment level 5- Degree of gingival enlargement. 6- BANA reaction of the dental plaque. 7- Total amount of IL-l B level of the GCF. The results of the study revealed that 70% of the patients in the orthodontic group showed gingival or periodontal change at one or more of the sites examined. The mean plaque index and PBI scores were higher in the orthodontic than the control group (P<0.01). The PPD and AL were slightly higher in the orthodontic group(P<0.05). About 24.8%of the sites examined in the orthodontic group show slight to moderate gingival hyperplasia. The dental plaque at the orthodontic band or brackets (900 site out of 1200 site) showed BANA positive reaction. This denotes increase in number of bacteroid ssp, fusobacteria and spirocheates. The total amount of IL- 1ß in the GCF was statistically significant higher at the teeth subjected to active orthodontic force than banded teeth not subjected to active force. From the results of the present study we conclude that unwanted effects of orthodontic treatment is a fairly common problem among adolescents. The change in the ecology of tne dental plaque at banded or bonded sites together with increased level of IL-1ß secreted as a result of orthodontic force or in the course of gingival int1ammation may in part responsible for these effects.  ISSN : 0  Journal Name : Egyptian Dental Journal  Volume : 48  Issue Number : 1  Publishing Year : 2002 AH 2002 AD  Article Type : Article  Added Date : Tuesday, June 17, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email زهير مرشد Murshid, Zoheri Investigator Doctorate zmurshid@kau.edu.sa مسعد الشربيني ElShirbiny, Mosaad Researcher Doctorate mmkhaleel@kau.edu.sa Files File Name Type Description  PERIODONTAL COMPLICATIONS OF ORTHODONTIC THERAPY.pdf pdf   Back To Researches Page
