Reliability of information on YouTube™ regarding pediatric dental trauma.

BACKGROUND/AIM: Traumatic dental injuries are a common health problem in children. The aim of this study was to evaluate the quality of the video contents on YouTube™ regarding traumatic dental injuries in children taking into account the information of IADT, and to analyze whether it is useful for patients and dentists. MATERIAL AND METHODS: A search was performed on YouTube™ using the search term "trauma in pediatric dentistry" with the default filter set to "sort by relevance". Based on this search, 127 videos were included. Demographic data such as the source, type, duration, upload date, number of likes and dislikes, interaction index, and viewing rate of the videos were recorded. Using a 23-point scale for video content analysis, they were classified into groups as low, moderate, and high content. RESULTS: A total of 127 videos were analyzed. Most of the videos were uploaded by healthcare professionals (n = 90; 70.8%). The average length of the videos was 16.4 min (range: 0.6-122.9 min; median: 7.8). The average number of views of each video was 3702.9 views (range: 4-87 103). The average interaction index (views/day) was 2.4 views (range: 0.00-19.5). The average viewing rate was 522.3 (range: 1.8-6381.2). The average number of "likes" was 45.0 (range: 0-619) and the average number of "dislikes" was 2.1 (range: 0-81). The mean number of days since the uploading of the video was 772.8 days (range: 23-3805). Most of the videos (94.4%, n = 120) were educational videos and 27 (21.2%), 40 (31.4%), and 60 (47.2%) were classified as high-content, moderate-content, and low-content groups, respectively. CONCLUSIONS: YouTube™ videos can be a useful resource for dental trauma in children. However, there is a need to improve the quality of YouTube™ videos uploaded by oral health professionals.

Investigation of neurodegenerative and inflammatory processes in sleep bruxism.

Objective: The present study aimed to evaluate the anxiety and optical coherence tomography (OCT) findings in patients with sleep bruxism (SB) and to develop objective measurements to assess the neurodegenerative and inflammatory processes associated with this disease. Methods: A group of 40 SB patients were compared with a control group consisting of 40 healthy individuals (without SB). Anxiety results and the OCT measurements of retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), and choroidal thickness were assessed in both groups. Results: Anxiety values in the bruxism group were significantly higher than those in the control group. The measurements of RNFL, IPL, and GCL in the bruxism group were significantly lower than the control group, whereas the choroidal thickness was significantly higher. Conclusion: According to literature, this is the first study that analyzed the changes in the retinal structures in bruxism, which revealed that SB is a neurodegenerative and inflammatory process.

The influence of flap design on sequelae and quality of life following surgical removal of impacted mandibular third molars: A split-mouth randomised clinical trial.

BACKGROUND: Surgical removal of impacted mandibular third molar is one of the most frequently performed interventions in oral and maxillofacial surgery. OBJECTIVES: To compare two different flap designs in terms of sequelae and quality of life following surgical removal of impacted third molars. METHODS: This prospective, randomised, split-mouth clinical study involved patients referred for surgical removal of bilateral symmetrical impacted mandibular third molars. Envelope flap and modified triangular flap techniques were used. The effects of flap design on trismus, swelling, wound dehiscence, alveolar osteitis, haematoma, infection and quality of life were evaluated on post-operative days 3 and 7. Pain levels were assessed on post-operative days 1, 3 and 7. RESULTS: Significant differences were determined between the two groups in terms of trismus, pain and wound dehiscence scores on post-operative day 3. However, on post-operative day 7, this difference was observed only in trismus. Statistically significant differences were also determined between the two groups on post-operative day 3 for social isolation and eating subscale scores as well as total quality of life score. CONCLUSION: Based on the study findings, the modified triangular flap may be superior to the envelope flap in terms of pain, trismus, and wound dehiscence in the first 3 days after impacted third molar surgery and may have a better impact on quality of life during this process.

Analysis of synovial fluid visfatin level in temporomandibular joint disorders.

Background: Biochemical analysis of synovial fluid (SF) is an important means of understanding the pathogenesis of temporomandibular disorder (TMD) and confirming diagnoses made using traditional methods. Objective: The aim of this study was to determine whether or not SF visfatin levels can serve as a biochemical marker in the diagnosis of TMD. Method: Sixty samples of SF were obtained from 60 patients with internal derangement (ID) or osteoarthritis (OA). Visfatin in the SF was examined by enzyme-linked immunosorbent assay (ELISA). Result: Visfatin levels showed positive correlations with TMD pain and ID stage and a negative correlation with maximum mouth opening. In addition, Visfatin levels in joints with OA changes in the condyle were significantly higher in comparison to joints with no OA changes. Conclusion: Within the limitations of this study, it can be concluded that visfatin may play a role in the pathogenesis of TMD.

A decision analysis for periapical surgery: Retrospective Study.

BACKGROUND: Periapical surgery is now a reliable therapeutic procedure for the treatment of teeth with periapical lesions, particularly when orthograde retreatment is problematic. However, little information is available regarding treatment planning of cases referred for periapical surgery. Therefore, this study was conducted to analyze and evaluate the factors that affect the decision-making process for periapical surgery. MATERIAL AND METHODS: This study retrospectively assessed clinical and radiographic data from patients undergoing periapical surgery. The factors involved in deciding to perform periapical surgery were classified into technical, biological, and combined factors. RESULTS: Out of 821 patients, 544 (66.3%) underwent endodontic treatment/retreatment, 204 (24.8%) were treated with coronal restorations and 60 (7.3%) were treated with post. Periapical surgery was indicated for biological reasons in 35% of patients and for technical reasons in 17.9%. The common biological factor was persistent clinical symptoms (19.7%). The most common technical cause was failure of previous endodontic treatment (66.3%). Nearly half of all periapical lesions (45%) were <5 mm in size. Periapical surgery was justified in only 434 (52.9%) subjects. CONCLUSIONS: We suggest that it is very important for patients to be informed and encouraged about endodontic retreatment in order to reduce unnecessary surgical procedures. Key words:Periapical surgery, case selection, treatment planning.

A comparison of diode laser and Er:YAG lasers in the treatment of gingival melanin pigmentation.

OBJECTIVES: This study compared the use of diode and Er:YAG lasers in treating gingival melanin pigmentation (GMP) in terms of gingival depigmentation, local anesthesia requirements, postoperative pain/discomfort, depigmentation effectiveness, and total treatment duration. STUDY DESIGN: Twenty patients (13 female, 7 male) referred with GMP were enrolled in the study. Patients were randomly divided into 2 groups. Group 1 was treated with a gallium aluminum arsenide diode laser with a continuous wavelength of 808 nm, and group 2 was treated with an Er:YAG laser with a continuous wavelength of 2,940 nm. Gingival depigmentation was performed by applying the laser at 1 W. Treatment was administered on a weekly basis until a normal pink gingival color was observable in clinical examination and photographs. In addition, patients were asked to evaluate the procedure by using a self-administered questionnaire. RESULTS: Procedures were carried out without the need for any topical or local anesthetic, and no unpleasant events occurred during the actual procedure or the healing period. The total length of treatment was significantly shorter with the diode laser (group 1) than with the Er:YAG laser (group 2; P < .05). No melanin recurrence was detected during any follow-up session. CONCLUSIONS: Diode and Er:YAG lasers administered at 1 W both result in satisfactory depigmentation of GMP.
