    Are YouTube videos related to dental implant useful for patient education?
    (Elsevier, 2020) Menziletoglu, D.; Guler, A. Y.; Isik, B. K.
    Purpose: The aim of the research was to assess the quality of obtained information from YouTube videos related to dental implant. Materials and methods: Dental implant word was used as a key word in YouTube videos in this study. Videos were evaluated by three oral and maxillofacial surgeons. The first 150 videos were screened. After exclusion criterias, seventy-four videos were investigated regard to content's usefulness. The usefulness scores of the videos were poor (0), moderate (1) and excellent (2). Upload sources were recorded that were categorized as the individual users, health care professionals, and health companies. The type of videos was classified 3 sections: educational videos, patient's experience, and scientifically erroneous. We examined videos for the content presence in eight non-mutually exclusive domains of dental implant. Results: Seventy-four videos were evaluated. The usefulness score of the videos ranged from 0-2 and the average was 0.324. The most discussed topics were regarding with procedures of dental implant (42.57%), however, the least one was related to contraindications (1%). No significant correlation was found between the source of upload and video usefulness score (P = 0.086). There was a significant difference between number of comments and the video types. (P = 0.002). Conclusion: Our outcome emphasized that YouTube videos related to dental implant were a limited source for the patients. Many issues regarding dental implant were ignored in these videos. (c) 2020 Elsevier Masson SAS. All rights reserved.

    Assessment of pulp volume changes after surgically assisted rapid palatal expansion
    (Elsevier, 2021) Guler, A. Y.; Isik, B. K.; Esen, A.; Menziletoglu, D.
    Maxillary transverse deficiency is a common skeletal problem. When the patient is younger, it is treated by rapid palatal expansion by using orthodontic appliances. If this fails or the patient is older, which means skeletal growth is completed, surgically aided rapid palatal expansion (SARPE) becomes necessary. In this technique, after the osteotomies have been made, the two maxillary bones are distracted by tooth-borne device. Since a tooth-borne device will apply the distraction forces on the teeth, the pulp volumes may change. Our aim was to investigate the volume changes of the tooth pulps after SARPE in which a tooth-borne device was used. We scanned our database and included 20 patients (7 males and 13 females) aging between 16 and 30 (mean 19.5 +/- 3.97) to this retrospective study. All the patients had undergone SARPE surgeries and they had pre-surgery and postconsolidation cone beam computerized tomography (CBCT) images. All the surgeries had been done in similar ways; all the patients had used similar tooth-borne modified acrylic bonded expansion device. We divided the maxillary teeth into three groups: the incisors, the premolars and the molars. We imported the CBCT images of each patient into 3D Slicer software. We calculated volumes of pulps for all maxillary teeth. We compared volumes with paired t test. Statistical significance level was accepted as P < .05. The devices had been left in place between 83 and 179 days including distraction and consolidation periods (mean 121.35 +/- 27.83 days). Amount of the expansions varied between 6.03 mm and 11.16 mm (mean 7.19 +/- 1.18 mm). We found a statistically significant decrease of the pulp volumes in incisor, premolar and molar teeth (P < .001) between pre-surgery and postconsolidation periods. When using tooth-borne devices in SARPE, their impacts on teeth pulps should also be considered. (C) 2020 Elsevier Masson SAS. All rights reserved.

    Comparison of two different flap designs for bilateral impacted mandibular third molar surgery
    (Elsevier, 2020) Menziletoglu, D.; Guler, A. Y.; Basturk, F.; Isik, B. K.; Erdur, E. A.
    Objective: We compared the effect of lingual-based triangular flap with buccal-based triangular flap on postoperative complications in impacted third molar surgery. Material and methods: Thirty patients aged between 18 and 36 (mean age 19.65 +/- 2.14) were included. They all had bilateral impacted third molars. We used buccal-based triangular flap on a randomly selected side (Group 1) and lingual-based triangular flap on the other side (Group 2). We evaluated pain during 7 days after the surgery; swelling and trismus on postoperative 2., 7. and 14. days; wound dehiscence and alveolar osteitis incidence on postoperative 7. and 14. days. Results: Pain was significantly higher in Group 2 during 7 days postoperatively (P < .05). Trismus and swelling were also more prominent in Group 2 on postoperative days 2 and 7. In Group 2, the duration of the surgery in was longer than Group 1 (P < .05). In Group 1, 17 patients (56.7%) had wound dehiscence and 6 patients (20%) in Group 2 (P < .05). No alveolar osteitis developed in either groups. Conclusion: The buccal-based triangular flap seems better with regard to postoperative pain, swelling and trismus. On the other hand, the lingual-based triangular flap had a lesser incidence for wound dehiscence. (C) 2019 Elsevier Masson SAS. All rights reserved.
