RESUMO
The objective of the study was to determine the effects of fixed orthodontic appliances on periodontal health. This prospective longitudinal self- controlled study was conducted on 54 adolescents [14 males, 40 females] who were scheduled for fixed orthodontic treatment in January 2013. Dental plaque accumulation, gingival inflammation and periodontal health were assessed. These periodontal indices and plaque indices were determined prior to the placement of fixed appliances and two weeks after the beginning of orthodontic treatment. All clinical values started to increase after the placement of fixed appliances. Treatment with fixed appliances in adolescents may transitionally increase the values of plaque and gingival indices. Oral hygiene measures, patient education and motivation are all very important after placement of fixed and removable appliances
RESUMO
The purpose of this study was to identify the causes of primary teeth extraction, and the most frequently extracted tooth among Jordanian children who were seen at pedodontic clinic at King Hussein Medical Center [KHMC] in Amman - Jordan. Two hundard fifty pediatric patients formed the study group. Their ages ranged from 3 to 13 years. They had one primary tooth extracted under local anesthesia. The reasons for extraction of teeth in these children seen over a period of 2 months and their ages, gender and the tooth extracted were recorded. The results revealed that the most common cause of primary tooth extraction was dental caries [57%] and the first primary molars were the most commonly extracted teeth [40%]. No gender, differences were noticed but there were obvious difference in age. In subjects [3-6] years, primary central incisors were the most common teeth extracted [54%], while in patients [7-9] and [10-13] years the first primary molars were the most common extracted [52% and 43%] respectively. The results of this survey indicated that dental caries was the leading cause of extraction of primary teeth in Amman - Jordan
