ABSTRACT
Purpose: The aim of this study was to evaluate YouTube videos as a source of information for digital indirect bonding techniques. Materials and methods: The keyword "digital indirect bonding" was first searched on YouTube, resulting in 57 recorded videos. Descriptive parameters, including source, target audience, purpose, duration, upload date, number of likes, dislikes, views, and comments, were then evaluated. After this initial assessment, the interaction index and viewing rate were calculated. Video content quality was determined using a 5-point scale that categorized videos as having poor, moderate, or good content quality. This rating was based on the presence and discussion of various topics related to digital indirect bonding, including digital scan, digital bracket placement, transfer tray production from a 3D-printed model or direct production as a 3D-printed tray, clinical application, and advantages and/or disadvantages. The videos were assessed for quality using the global quality scale (GQS) and video information and quality index (VIQI). Statistical evaluation was conducted using Kruskal-Wallis, Chi-square, and Pearson correlation analysis, and intraclass correlation coefficients were calculated to determine the rating reliability. Results: The majority of the videos were classified as having poor content quality (41.9%), followed by moderate (38.7%) and good (19.4%) content quality. No significant differences were found between the videos in terms of descriptive parameters. However, videos with good content quality had significantly higher GQS and VIQI scores than moderate and poor content videos. The total content showed significant correlations with GQS and VIQI (r=0.780 and r=0.446, respectively; plt;0.05). Conclusion: In conclusion, while the majority of YouTube videos regarding digital indirect bonding were of poor content quality, those that were of good content quality could be considered a useful source of professional information.
ABSTRACT
OBJECTIVES: This randomized clinical trial aimed to evaluate the effects of digital indirect bonding (DIB) compared to the direct bonding (DB) technique in terms of enamel demineralization and periodontal status. MATERIALS AND METHODS: A total of 24 patients (17 females, 7 males) with a mean age of 13.83⯱ 1.55 years were bonded using DB and DIB techniques using a split-mouth study design. Bonding techniques were randomly allocated to quadrants. Demineralization measurements were performed with the DIAGNOdent pen (Kavo, Biberach, Germany) from four sides (distal, gingival, mesial, and incisal/occlusal) of all brackets immediately after bonding, 1 month (T1), and 6 months (T2) after bonding. Periodontal measurements were taken before bonding and at the same time points (T1 and T2). Data were statistically analyzed with the Mann-Whitney U test to determine possible differences between groups. RESULTS: Incisal/occlusal sides exhibited the lowest demineralization values at T2. The gingival side of upper centrals, mesial side of upper laterals, and distal sides of upper first premolar and lower laterals brackets bonded with the DIB technique exhibited significantly increased demineralization compared with the DB technique from T0 to T2 (pâ¯< 0.05). Periodontal parameters increased 1 month after bonding and decreased during the follow-up. Bonding technique showed no statistically significant difference in plaque index, gingival index, and bleeding on probing values at any time interval. CONCLUSION: There were many locations around the brackets with significantly higher demineralization after 6 months in patients who received digital indirect bonding compared to the DB group. Although periodontal health was generally adequate, complete removal of adhesive flash should be carefully carried out to decrease the risk of demineralization during indirect bonding technique with digital workflows.
ABSTRACT
INTRODUCTION: The aim of this case report was to present the dentofacial changes obtained with bone anchorage in a Class II patient with moderate to severe crowding. METHODS: A boy, aged 14.5 years, with a dolichofacial type, convex profile, and skeletal and dental Class II relationships was examined. After evaluation, functional treatment with bone anchorage and 4 first premolar extractions was decided as the treatment approach. Miniplates were placed on the buccal shelves of the mandibular third molars. The hook of the anchor was revealed from the first molar level. After surgery, the 4 first premolars were extracted to retract the protrusive mandibular incisors. The maxillary and mandibular first molars were banded, and a lip bumper was inserted to apply elastics and to help distalize the maxillary first molars. Orthodontic forces of 300 to 500 g were applied immediately after placement, originating from the miniscrews to the hooks of the appliance to advance the mandible. RESULTS: After 20 months of treatment, the patient had a dental and skeletal Class I relationship, the mandible was advanced, the maxilla was restrained, and overjet was decreased. CONCLUSIONS: The combination of a bone anchor, Class II elastics, and an inner bow is a promising alternative to functional treatment, along with extractions, in Class II patients.
