RESUMO
BACKGROUND: This study aimed to evaluate the mandibular bone structure of patients using oral anticoagulants (OACs) vitamin K antagonist drugs (warfarin) and other OACs including direct oral anticoagulants [(DOACs) apixaban, rivaroxaban, dabigatran, edoxaban]. Analyses were based upon the fractal dimension (FD), the panoramic mandibular index (PMI) and the Klemetti index (KI), which is also known as the mandibular cortical index (MCI). METHODOLOGY: Ninety participants were divided into three groups: group 1: 30 systemically healthy individuals who had not used any anticoagulants before, group 2: 30 individuals using warfarin, and group 3: 30 individuals using DOACs. FD was used to analyze trabecular bone architecture in the condyle, angle, and two sites in the alveolar bone. PMI was used to evaluate the quantity of cortical bone and KI was used to evaluate the cortical bone quality. RESULTS: There was no difference between the groups regarding FD analysis and KI; however, a difference was found between groups 1, 2, and 3 in the PMI (P≤ 0.001). The PMI in group 1 was higher than in groups 2 and 3. CONCLUSION: Mandibular radiomorphometric indices can be used on panoramic radiographs to evaluate the quantity of mandibular cortical bone in patients using oral anticoagulants.

PURPOSE: The aim of this study is to emphasize the importance of using cone-beam computed-tomography in order to determine the anatomical structures and their variations before the treatment in patients who apply to the dentist clinic for implant treatment. METHODS: In the study, CBCT images of 500 adult patients (240 female and 260 male), aged between 21 and 82 years, who applied for implant treatment due to missing teeth, were retrospectively analyzed. Anatomical structures and variations such as nasopalatine canal(NPC), canalis sinuosus(CS), antral alveolar artery(AAA), were evaluated in multiplanar reformation(MPR) sections which are axial, sagittal and coronal can be viewed in consistence with each other. RESULTS: The incidence of anatomical variation of CS in the right region was similar according to gender. The "Funnel" appearance of the NPC shape was found most common shape in both female and male patients (n = 89; 37.1% for females and n = 71; 27.3% for males). CONCLUSION: CBCT has become the most popular 3D imaging method in dental practice especially for planning dental implants. Understanding the relationship with important anatomical structures before implant applications is crucial in dealing with potential complications that may arise afterward. Assessing significant anatomical structures by CBCT and taking precautions against possible risks facilitate the work of dentists during and after procedures.

Background This study aimed to assess the reliability, quality, and content of the information provided by YouTube™ videos on oral health during pregnancy to reveal the effectiveness of the videos for patients. Methodology This cross-sectional study was conducted by two experienced dental specialists. They initiated the study by searching for YouTube™ videos using the keyword 'pregnancy oral health'. The videos were then assessed based on various parameters, including origin, type, number of days since upload, duration, number of views, number of likes and dislikes, and number of comments. The specialists also calculated the interaction index and viewing rate. The reliability and quality of the videos were evaluated using the global quality scale (GQS) and modified DISCERN (mDISCERN) scales, while the content was assessed with the comprehensiveness tailor-made index. The data were analyzed with the Shapiro-Wilk, the Kruskal-Wallis, the post-hoc Bonferroni, and Fisher's exact tests. The significance level was set at P < 0.05. Results After reviewing initially 224 videos, 129 were included in the study. Health professionals were the publishers of most videos. A statistically significant positive correlation was found between content scores and video duration, number of comments, interaction index, and total DISCERN scores (p<0.05) (r=0.445, r=0.186, r=0.552, r=0.241, r=0.200, r=0.681, respectively). Statistically significant associations were found between GQS scores, video duration, number of comments, and total mDISCERN scores (p<0.05) (r=0.510, r=225, r=0.156, r=0.768, respectively). Statistically significant relationships were identified between the total content score, video source, and GQS (p<0.05). According to the total content score, 57.4% of the videos had a score of 2, 35.7% had a score of 1, and only 7% had a score of 0. Conclusions This study's findings underscore the significant variability in the scientific accuracy, content, and quality of health information on the Internet, particularly on YouTube™. It reveals that, while there are videos that provide rich content and high-quality information, there are also poor-quality and inadequate videos that may mislead patients. Health professionals should be aware of misinformation found on YouTube™ and ensure that patients always have access to accurate and reliable information.
RESUMO
BACKGROUND: Several potential benefits have been attributed to the platelet-rich fibrin (PRF), including enhanced tissue healing properties. In this study, we hypothesized that the application of PRF as an adjunct to conventional scaling and root planing (ScRp) would enhance the outcomes of non-surgical periodontal therapy. METHODS: The present study was a split-mouth randomized controlled clinical trial design in 24 deep periodontal pockets in 12 patients with periodontitis. The pockets were randomly assigned as test or control. The test group received PRF as an adjunct to ScRp, whereas the control group received ScRp only. We measured periodontal clinical parameters at baseline, 3, and 6 months after the treatments. To study the initial healing in response to treatment, transforming growth factor-ß (TGF-ß) and collagen-1 (Col-1) in gingival crevicular fluid (GCF) were measured using enzyme-linked immunosorbent assay at baseline, third, seventh, and 14th days. RESULTS: The test group showed a significantly greater pocket reduction, higher clinical attachment gain, and less gingival recession than the control group at 3 and 6 months. The test Col-1 levels (1.27 ± 1.05, 1.35 ± 0.76, 0.97 ± 0.53 ng/site) and TGF-ß levels (11.93 ± 2.68, 12.54 ± 3.66, 17.19 ± 11.66 pg/site) were higher than the control Col-1 levels (0.76 ± 0.20, 0.84 ± 0.24, 0.57 ± 0.19 ng/site) and TGF-ß levels (6.34 ± 1.67, 6.35 ± 3.44, 7.51 ± 2.85 pg/site) at all measurement days respectively. CONCLUSIONS: Non-surgical application of the PRF as an adjunct to conventional ScRp may effectively improve the periodontal clinical parameters via increasing expression of the GCF TGF-ß and Col-1 levels.

AIM: The aim of this case report is to present the trans-sinusoidal pathway used to remove a displaced maxillary third molar from the infratemporal fossa and review the English literature regarding the techniques used. CASE REPORT: A 21-year-old male patient was referred with the findings of an oroantral fistula on the left maxillary vestibular first molar region and slight restriction of mouth opening. The patient underwent a maxillary sinus surgery in order to remove a sinus retention cyst via Caldwell-Luc access in a dental clinic 4 years ago. A computerized tomography scan showed the inverted third molar to be located in the infratemporal fossa, just between zygomatic arch and lateral pterygoid plate. The tooth was accessed through the remaining lateral bone defect from the Caldwell-Luc approach of the lateral sinus wall. The bone defect was extended. The posterior bony wall of the maxillary sinus was removed via a surgical burr. After that, the displaced tooth was exposed. The tooth was mobilized via Warwick James elevator downwards and removed with a forceps. CONCLUSION: Access for surgical removal of the tooth from the infratemporal fossa is not only difficult but also has potential for morbidity due to the structures running through it. Wide incision in the maxillary sulcus and blunt dissection are reported with lower success rates and usually necessitate a second intervention via extraoral route. Trans-sinusoidal approach might be an old fashioned but relatively successfully attempt in the removal of the upper third molars from the infratemporal fossa. Considering the time of removal, if no symptoms were present, it is beneficial to wait for a couple of weeks thus facilitating development of fibrous surrounding around the tooth.
