    Cleft Lip and Palate YouTube Videos: Content Usefulness and Sentiment Analysis
    (Sage Publications Inc, 2021) Bozkurt, Aylin Pasaoglu; Aras, Isil
    Objective: This study aimed to describe the content of YouTube videos about cleft lip and palate (CLP) and to describe the sentiment analysis of related comments. Design: Retrospective, YouTube video, and sentiment analysis. Methods: YouTube videos (N = 112) about CLP were examined, including demographics and ratings of quality and usefulness. Comments on CLP (N = 205) were classified by content, and measured from negative (-5) to positive (+5) with a sentiment analysis program. Results: Videos were uploaded most often by universities and hospitals (25%) and health information sites (22%). Most videos were educational (49.1%) or described patient experiences (48.2%). The most frequent video topics were terminology, CLP treatment, and prenatal diagnosis information. Based on the comprehensiveness of CLP topics covered, videos were generally rated by authors as moderately useful (31.5%) or very useful (35.7%). Comments were mostly made by people with CLP (79%), and the median sentiment scores were +3, and -2 for positive and negative sentiments, respectively. General content categories were positive comments (24.8%), provided information about themselves (24.4%), negative comments (19.5%), comments on usefulness of video (17.6%), or advice (9.3%). While 36.1% of comments noted no difficulties, the remaining comments included difficulties with surgery pain (13.2%), psychological state (12.2%), embarrassment (11.7%), physical appearance (10.2%), long term therapy (9.8%), and speech problems (6.8%). Conclusions: Although useful and educational YouTube videos were available, the variability of content quality suggests that caution be used in relying on videos for information and that experts in CLP treatment should be consulted.

    Comparison of 2 treatment protocols using fixed functional appliances in Class II malocclusion: Treatment results and stability
    (Mosby-Elsevier, 2020) Bozkurt, Aylin Pasaoglu; Aras, Isil; Othman, Eman; Aras, Aynur
    Introduction: The objective of this research was to compare the 2 treatment protocols including a functional mandibular advancer (FMA; Forestadent, Pforzheim, Germany) followed by multibracket appliances (MBAs) vs a Forsus device (3M Unitek, Monrovia, Calif) in combination with MBA concerning treatment outcomes and posttreatment stability. Methods: This study was conducted using lateral cephalograms of patients who were treated with MBA, which was used either after an FMA or concurrently with a Forsus device, and of patients who had untreated Class II malocclusion (control group). Each group consisted of 19 subjects in cervical stage 2 or cervical stage 3 stages according to the cervical vertebral maturation index. Cephalograms were taken for the treated groups at T1 (pretreatment), T2 (completion of the MBA treatment), and T3 (at least 2 years after T2). Results: Significant intergroup differences at the T1-T2 period were observed in favor of the FMA concerning mandibular advancement, intermaxillary relationship, and mandibular elongation. With Forsus treatment, restrained maxillary growth and a slightly improved intermaxillary relationship rebounded after treatment (P <0.05). At the end of treatment, mandibular incisor protrusion and occlusal plane rotation were greater in the Forsus group than in the FMA group (P <0.05), and maxillary incisor retroclination was significant in the Forsus group. During the posttreatment period, although no significant changes were present in the incisors' inclination, relapses of the T1-T2 improvements in overjet and overbite and the recidive of the occlusal plane rotation were significantly higher in the Forsus group. Conclusions: Treatment protocol including an FMA was found to be more effective with mandibular skeletal effects and was more stable with a lesser degree of relapse in overjet and overbite than the Forsus protocol.

    Comparison of microbial adhesion and biofilm formation on orthodontic wax materials; an in vitro study
    (Elsevier Taiwan, 2020) Bozkurt, Aylin Pasaoglu; Unlu, Ozge; Demirci, Mehmet
    Background/purpose: Orthodontic wax materials are available on the dental market and are given by orthodontists due to pain, sores and irritation caused by treatment. The aim of the study was to compare biofilm formation and microbial adhesion at different time points on different protective materials used against orthodontic wounds in vitro. Materials and methods: Microbial adhesion and biofilm formation were evaluated against Streptococcus mutans ATCC 25175 and Lactobacillus acidophilus ATCC 4356 standard strains on orthodontic wax materials at the 0, 24th, 48th, 72nd, 96th and 120th hour. The Kruskal Wallis test and Bonferroni test were used for statistical evaluations. Statistical significance was set at p < 0.05. Results: It was observed that S. mutans formed statistically significantly more biofilm on OrthoDots (R) CLEAR (OrVance) than Ora-Aid (TBM Corporation) at the 48th hour (p < 0.05). Furthermore, L. acidophilus formed statistically significantly more biofilm on OrthoDots (R) CLEAR (OrVance) than Brace Gard (R)(Infa-Lab Inc.) at the 72nd, 96th and 120th hours (p < 0.05). Conclusion: Significant differences were noted among the different orthodontic wax materials and both S. mutans and L. acidophilus created biofilm on all waxes at different time points in vitro. To prevent biofilm formation, these waxes need to be refreshed and should not be used for more than 24 h. According to our study, biofilm production performances of pathogens on Brace Gard (R)(Infa-Lab Inc.) are minimal and therefore it may be a better option to use in clinics. However, to our knowledge, this is the first study investigating biofilm formation on waxes and more studies are needed in this field.

    Effects of mechanical vibration on miniscrew implants and bone: Fem analysis
    (Elsevier Masson Sas Editeur, 2019) Bozkurt, Aylin Pasaoglu
    Objective > The aim of this FEM study was to assess the effect of mechanical vibration force on miniscrews and stress distribution in cortical and trabecular bone around miniscrews. Methods > A 3D model was created using a CBCT image of a patient. Three different analyses were performed on a single model. Material properties, boundary conditions and the quality of applied forces (direction and magnitude) were defined. 150 gf, 150 gf and 30 Hz (0.2 N), 150 gf and 111 Hz (0.06 N) were applied to miniscrew from distal to mesial and from sulcus to alveolar crest direction like a power arm application. The first moment effect of force and vibration were evaluated by using Algor Fempro FEM analysis program. Von Mises and principal stress distribution on miniscrews and bone layers were evaluated by different force and vibration applications. Results > It was seen that Von Mises stress distribution on miniscrew was located on the neck region and the highest stress levels were observed in the 1st analysis (27,0159 N (mm(2))), which was only force application. The loading of the cortical bone in the proximity of the miniscrew was clearly greater with only force application rather than force and vibration application together. Maximum and minimum principle stress values gradually decreased while vibration value increased. Conclusion > It was concluded that mechanical vibration force might reduce the peri-implant loading of the bone and stress levels on the miniscrews.

    Objective > To investigate video content on YouTube (TM) related to impacted canine and impacted canine surgery. Materials and Methods > In this cross-sectional study, the term impacted canine tooth was searched on YouTube (TM). After excluding duplicates, irrelevant videos, non-English-language videos, no audio-no video contents, sixty-one videos were independently examined by 3 reviewers. Videos were categorized as not useful, slightly useful, moderately useful, and very useful by using an 8-point score list for evaluating the value of the videos in providing patients information about impacted canine teeth and surgery. Chi-square test was performed for categorical variables and differences between groups were compared with Kruskal-Wallis. Correlations were analysed using Spearman test. Statistical significance was set P < 0.05. Results > Most of the videos, 42.6%, n = 26 were uploaded by healthcare professionals [dentists, orthodontists, surgeons] and 29,5%, n = 18 were uploaded by laypersons for sharing personal experiences. There were 3 [4.9%] not useful videos, 15 [24.5%] slightly useful videos, 27 [44.2%] moderately useful videos, and 16 [26.2%] very useful videos. There was no significant difference between the viewing rate according to the source of upload [P = 0.398 > 0.05]. There was a significant difference between the interaction index according to the source of upload. This difference was in the laypersons and the others [.033 < 05]. Conclusion > Healthcare specialists should be aware of the content of the video-sharing platforms and direct their patients to correct and reliable e-information resources.
