Filter by:The aim of this 2-arm parallel trial was to evaluate enamel demineralization after an indirect bonding technique in comparison to a direct bonding technique group using the quantitative light-induced fluorescence method. Thirty-six patients who needed fixed orthodontic treatment were randomly separated into either the direct bonding group or the indirect bonding group. Eligibility criteria included moderate crowding in the maxillary and mandibular dental arch, good oral hygiene, absence of craniofacial anomalies, no previous orthodontic treatment and no deciduous, congenitally missing or extracted teeth. Randomization was made at the start of the study with a statistical analysis program (SAS Institute Inc., Cary, NC, USA.). For the patients in the indirect bonding group, bonding was performed with a flowable composite adhesive, while the patients in the direct bonding group received a bonding procedure with a conventional composite adhesive. Records were taken using quantitative light-induced fluorescence (QLF) with a Digital Biluminator (Inspektor Research Systems, Amsterdam, the Netherlands) in the pretreatment and posttreatment examination phases. The presence and extent of lesions on the buccal surfaces of all teeth, except the molar teeth, were assessed. The fluorescence loss, lesion area and percentage of fluorescence loss were determined using the system's software. The primary outcome of this study was evaluation of the effects of bonding techniques on white spot lesion formation by using the QLF method. Random sequence generation was performed with a computerized random 1:1 allocation using block sizes of 4. It was not possible for the clinicians and their interventions to be blocked. The patients and the specialists were blinded to the treatment groups when their treatment groups were aware.
The purpose of this investigation is intended to evaluate the efficacy of surgically facilitated orthodontic treatment (SFO) in terms of treatment time, incidence of root shortening, and occurrence of mucogingival side effects compared to conventional orthodontic therapy in patients undergoing orthodontic treatment to correct crowding and/or retroclination of their mandibular anterior dentition.
