    Comparison of retention characteristics of Essix and Hawley retainers
    (KOREAN ASSOC ORTHODONTISTS, 2012) Demir, Abdullah; Babacan, Hasan; Nalcaci, Ruhi; Topcuoglu, Tolga
    Objective: We aimed to compare the retention characteristics of Essix and Hawley retainers. Methods: Adolescents undergoing fixed appliance treatment at 2 centers were recruited for this study. Twenty-two patients (16 women and 6 men) wore Essix retainers (Essix group) while 20 (14 women and 6 men) wore Hawley retainers (Hawley group). The mean retention time was 1 year, and the mean follow-up recall time for both groups was 2 years. Two qualified dental examiners evaluated the blind patient data. Maxillary and mandibular dental casts and lateral cephalograms were analyzed at 4 stages: pretreatment (T1), post-treatment (T2), post-retention (T3), and follow-up (T4). Results: The results revealed that Essix appliances were more efficient in retaining the anterior teeth in the mandible during a 1-year retention period. The irregularity index increased in both arches in both groups after a 2-year post-retention period. The mandibular arch lengths increased during treatment and tended to return to their original value after retention in both groups; however, these changes were statistically significant only in the Hawley group. Cephalometric variables did not show any significant differences. Conclusions: The retention characteristics of both Essix and Hawley retainers are similar. [Korean J Orthod 2012;42(5):255-262]

    Effect of fixed appliances on oral malodor
    (MOSBY-ELSEVIER, 2011) Babacan, Hasan; Sokucu, Oral; Marakoglu, Ismail; Ozdemir, Hakan; Nalcaci, Ruhi
    Introduction: The objective of this study was to evaluate the effect of fixed appliances on oral malodor. Methods: Forty-one patients participated in this study. They were randomized into 2 groups: treated with fixed orthodontic appliances and untreated controls. Oral malodor measurements and the gingival and plaque indexes were recorded in each group by same periodontist. Measurements were taken from the study group before bonding, 1 week after bonding, and 4 weeks after bonding. The control group's measurements were made at the same time. Results: Oral malodor and the gingival and plaque indexes were significantly increased 1 week after bonding (P < 0.05). Oral malodor was increased at 4 weeks after bonding (P > 0.05). The comparison of the groups showed differences 1 week and 4 weeks after bonding. Conclusions: The oral malodor reached the critical level during fixed orthodontic treatment. Oral malodor could indicate a need to evaluate oral health and remind patients of the importance of maintaining ideal oral hygiene. (Am J Orthod Dentofacial Orthop 2011;139:351-5)
