Does YouTube™ offer high quality information? Evaluation of accelerated orthodontics videos.

BACKGROUND: YouTube™ is the foremost source of videos of all kinds of issues. OBJECTIVES: The aim of this study was to investigate videos related to accelerated orthodontic treatment on YouTube™ in terms of characteristics, content, popularity and viewers' assessments. METHODS: Six keywords related to accelerated orthodontic treatment were searched on YouTube™. After sorting by view-count, all 116 videos were evaluated, and the exclusion criteria were defined as: another language than English, unrelated to the topic, poor video quality and duplication. The remaining 80 videos were analyzed for general characteristics, primary purpose, information content, audio-visual quality. Also, viewers' interaction index, and viewing rate formulas were calculated for each video. RESULTS: The final 80 videos were viewed by users for 177,328 times in total. Most videos were uploaded by an educational institution (n = 40; 50.0%), followed by orthodontists (n = 20; 25.0%). Most of the videos (51.25%) were classified as having excellent general information content, 30.00% were rated as moderate, and 18.75% were rated as poor. The videos generally involved educational content (47.50%), followed by product presentation (20.00%), and then technical details about accelerated orthodontics (11.25%). Only 6.25% of the videos (n = 5) had viewers' interaction index values of greater than 3.00. Videos with excellent content had significantly higher interaction index values than others (p < 0.001). CONCLUSIONS: YouTube™ could be preferred as an important source for patient information about accelerated orthodontics. Reliable informative videos should be uploaded by orthodontists or dental professionals in accelerated orthodontics.

Evaluation of milk fat globule-epidermal growth factor-factor VIII and IL-1ß levels in gingival crevicular fluid and saliva in periodontal disease and health.

The aim of this study is to determine the levels of MFG-E8 and interleukin (IL)-1ß in saliva and gingival crevicular fluid (GCF) associated with periodontal health and disease. Whole saliva and GCF samples were obtained from systemically healthy participants who were either periodontally healthy (n = 24) or suffered from gingivitis (n = 25) or chronic periodontitis (n = 25). Full-mouth clinical periodontal measurements, including bleeding on probing, probing depth, gingival index, plaque index, and clinical attachment level were also recorded. Enzyme-linked immunosorbent assay was used to estimate MFG-E8 and IL-1ß levels in the samples. Analysis of variance, Kruskal-Wallis tests, and Pearson correlation tests were used to analyse the data statistically. The total level of MFG-E8 in GCF was significantly higher in the healthy group than in the other two groups (P = 0.01). Salivary MFG-E8 levels did not differ significantly among the groups. There were negative correlations between the level of MFG-E8 in GCF and probing depth (P = 0.03), bleeding on probing (P = 0.001), plaque index (P = 0.003), and gingival index (P = 0.003). The total level of IL-1ß in GCF was significantly lower in the healthy group than in the groups with gingivitis and chronic periodontitis (P < 0.001). Salivary IL-1ß levels showed significant differences across all three groups (P < 0.001). The level of MFG-E8 in GCF was higher in the healthy group than in the periodontal disease groups. Furthermore, there was no difference between gingivitis and periodontitis groups. The relationship between MFG-E8 and periodontal status should be further investigated.

Comparison of piezocision and discision methods in orthodontic treatment.

BACKGROUND: Discision method may provide an alternative to the piezocision approach in accelerated orthodontic treatment. The purpose of this study was to investigate the efficacy of discision on accelerated orthodontic tooth movement in comparison to the piezocision method in moderate crowding Angle Class I malocclusions. METHODS: Thirty-five female individuals were included in this clinical study. The participants were classified into three groups as conventional fixed non-extraction orthodontic treatment only (OT, n = 14), piezocision in addition to fixed non-extraction orthodontic treatment (PG, n = 9), and discision in addition to fixed non-extraction orthodontic treatment (DG, n = 12). The piezocisions and discisions were performed 1 week after placement of bonding brackets. The patients were seen at 2-3 week-intervals. Initial Little's irregularity index scores were recorded from dental casts. Periodontal parameters were measured initially, after the 1-month orthodontic treatment. Probing pocket depth, bleeding on probing, plaque index, and gingival index were recorded. Visual analog scale (VAS) was performed over the first month at different times following the bracket bonding for pain assessment. The total orthodontic treatment duration was noted. RESULTS: The duration of orthodontic treatment was statistically decreased in PG and DG compared to OT (P = 0.003). There was no statistical difference between PG and DG in orthodontic treatment duration (P > 0.05). There was no statistical difference between the two experimental groups in terms of VAS and periodontal parameter values (P > 0.05). CONCLUSIONS: This is the first clinical orthodontic study to assess the effect of discision on the rate of orthodontic tooth movement. Discision is comparable to piezocision in terms of tooth movement acceleration, pain level, and periodontal status. The discision seems to be effective in reducing the time of orthodontic treatment.

Treatment of Different Oral Soft Tissue Lesions With Surgical Neodymium: Yttrium-Aluminum-Garnet Laser: Case Series.

INTRODUCTION: Oral soft tissue lesions cause discomfort and potentially serious clinical problems. CASE SERIES: These case reports present different gingival and/or mucosal lesions (pyogenic granuloma, verruca vulgaris, giant cell granuloma, fibroma, etc.) and the surgical treatment of these lesions with a neodymium:yttrium-aluminum-garnet (Nd:YAG) laser (320-µm optic fiber; 4 W; 100 mJ, 40 Hz; emission mode, pulsed, and contact mode). Patients were evaluated after laser surgery on degree of postoperative pain; discomfort; functional complications (eating and speech); and recurrence. Results indicated that patients had minimal postoperative pain, few functional complications, and low rates of pain. Laser surgery produced minimal bleeding, damage to the surrounding tissue, and post-surgical edema. CONCLUSION: In these cases, the Nd:YAG laser provided a non-bleeding environment at the surgical area with an acceptable operating time, quick postoperative hemostasis, good patient acceptance, low rates of pain, and no post-treatment adverse events among patients with oral soft tissue lesions.
