Cleft Lip and Palate YouTube Videos: Content Usefulness and Sentiment Analysis.

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.

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.

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®CLEAR (OrVance) than Ora-Aid (TBM Corporation) at the 48th hour (p < 0.05). Furthermore, L. acidophilus formed statistically significantly more biofilm on OrthoDots®CLEAR (OrVance) than Brace Gard®(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®(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.

Potential Patient Education of YouTube Videos Related to Wisdom Tooth Surgical Removal.

This present study aimed to evaluate the education of YouTube videos about wisdom tooth surgical removal for viewers. In this study, the term "wisdom tooth surgical removal" was searched on YouTube. After excluding duplicates, irrelevant videos, non-English-language videos; 92 relevant videos in English were independently examined by 3 reviewers. The videos were categorized as 'poor', 'moderate' and 'excellent' by scoring 9 points in order to evaluate the information they provided to the audience. Chi-square test was performed for categorical variables and differences between groups were compared with ANOVA-Kruskal Wallis. Correlations were analyzed using Pearson and Spearman test. Statistical significance was set P < 0.05. Majority of the videos (63%, n = 58) were uploaded by layperson for sharing personal experience, 19.6%, (n = 18) healthcare professionals (dentist, orthodontist, surgeon). There were 64 (69.6%) not useful videos, 19 (20.7%) moderately useful videos, and 9 (9.8%) very useful videos. There is no significant correlation between efficiency ratio and source of upload (P > 0.05). There is a significant relationship between efficiency ratio and interaction index (P = 0.019 < 0.05). Interaction indexes of poor useful videos are more than others. There is a significant relationship between the type of video and video demographics (all data' significant values < 0.05). Mean values of patient's experience are more than others. Healthcare professionals should be aware of the accuracy of information on the internet in order to guide patients.

Patients' and Parents' Perception of Functional Appliances: A Survey Study.

OBJECTIVE: To evaluate patients' and parents' perception of removable, fixed rigid, and fixed hybrid functional appliances and to compare their impacts on anxiety and discomfort during treatment in different age groups and genders. METHODS: Data were gathered by means of a questionnaire that included items presumed to be associated with orthodontic compliance. A self-administered questionnaire was used to quantify patients' and parents' perceptions. Three groups were formed regarding the type of functional appliance used: fixed rigid (Functional Mandibular Advancer, FMA), fixed hybrid (Forsus Fatigue Resistant Device, FRD), and removable (Twin Block, TB). Two separate questionnaires were used for the patients and their parents comprising the necessary context. Chi-square, Mann-Whitney U, and Kruskal-Wallis tests were used for data analysis. RESULTS: Patients needed less time to adapt to the FRD appliance. Eating difficulties were encountered by patients in the FMA group. Adolescents who had completed functional orthodontic treatment with a removable appliance had difficulties in controlling their saliva. Patients' and parents' perceptions were found to be in accordance with each other. CONCLUSION: Adolescents who had completed functional orthodontic treatment with fixed appliances had more difficulty in their daily life. Orthodontists should be aware of this impact caused by functional orthodontic treatment and should regularly encourage patients by reminding them of the improvements to be had by fixing the malocclusion.
