Objective: To investigate the effectiveness of using YOLO-v5x in detecting fixed prosthetic restoration in panoramic radiographs. Study Design: Descriptive study. Place and Duration of the Study: Department of Oral and Maxillofacial Radiology, Eskisehir Osmangazi University, Turkiye from November 2022 to April 2023. Methodology: For the labelling of fixed prosthetic restorations, 8,000 panoramic radiographs were evaluated using v5x architecture. In creating the dataset for this study, fixed prosthetic restorations were categorised as dental implant, crown, and implant-supported crown on dental panoramic radiographs. The labelled images were then randomly split groups: 80% for training, 10% for validation, and 10% for testing. The labelled panoramic images constituted the model's dataset, and leveraging the knowledge acquired during this learning stage, the model generated predictions in the testing Results: The majority of labelling data were dedicated to crown restorations. The precision and sensitivity values of were 0.99 and 0.98 for crowns, 0.98 and 0.99 for implants, 0.99 and 0.99 for pontics, and 0.99 and 0.99 for implant crowns, respectively. Conclusion: The results obtained in this study demonstrate a satisfactory success rate of YOLO-v5x in detecting dental thetic restorations. The high precision and sensitivity of the model indicate its strong potential to enhance clinical professional performance and contribute to the development of more efficient dental health services.

Background: This study aimed to investigate the homogeneity of the major salivary glands in multiple sclerosis (MS) patients using ultrasonography (USG), assess DMFT indices, measure resting salivary flow rates, and compare these values with healthy individuals. Methods: In this study, 20 individuals diagnosed with Relapsing-Remitting Multiple Sclerosis (RRMS) (mean age 36.15 ± 8.51) and 20 systemically healthy individuals (mean age 35.7 ± 9.22) were included. Oral and radiologic examinations were performed in all individuals. The parotid and submandibular salivary glands were examined using USG, and their homogeneity was assessed based on the scoring system recommended by the Outcome Measures in Rheumatology Clinical Trials (OMERACT) study group. Resting salivary flow rates and DMFT indices were measured, and the obtained data were subjected to statistical analysis. Results: The parotid glands exhibited more heterogeneity on USG within the MS patient group than the control group, with a statistically significant difference between the two groups (p = 0.015). A statistically significant correlation was observed in total homogeneity values between the patient and control groups (p = 0.021). Furthermore, the MS patient group exhibited higher DMFT indices and lower salivary flow rates than the control group. The difference between the DMFT indices and salivary flow rate between the patient groups was statistically significant (p = 0.004 and p = 0.002 respectively). Conclusions: The parenchyma of the major salivary glands in MS patients exhibited decreased homogeneity than the healthy controls. Additionally, the MS group showed a decrease in salivary flow rate and an increase in the DMFT index. Autonomic dysfunction and medications used for MS are thought to cause salivary gland hypofunction and dry mouth. It can be interpreted that hyposalivation and motor skill losses in MS patients lead to an increase in DMFT index.

Introduction. One of the critical parameters evaluated while planning orthodontic treatment for impacted canines in clinical practice is the relationship between impacted canines and adjacent anatomical structures. The nasopalatine canal (NPC) and maxillary sinus are anatomical formations that may be in close proximity to impacted canines. This study aimed to determine the relationship between palatally impacted canines, the maxillary sinus, and the NPC. Methods. A total of 105 impacted canines from 93 patients were evaluated using cone beam computed tomography (CBCT) images. The relationship between the impacted canine teeth, maxillary sinus, and NPC was assessed inside, outside, and at the border of the maxillary sinus floor and NPC walls. The millimetric distance between the impacted canine teeth and the borders of the maxillary sinus, the NPC, and the cortical bone of the palate was measured. Additionally, NPC morphology was assessed on the axial and sagittal CBCT images. Results. Of all the impacted teeth, 47.6% (3.8% inside, 43.8% at the border) were associated with the sinus, while 42.8% (15.2% inside, 27.6% at the border) were associated with the NPC. A significant moderate negative correlation (-0.32) was observed between age and the distance between impacted left canine teeth and the cortical bone of the palate. Additionally, when a Y-shaped NPC was present, the impacted canines were predominantly situated outside the canal. Conclusions. In this study, nearly half of the canines were located inside or at the border of the maxillary sinus and the NPC. Therefore, clinicians should carefully evaluate the relationship of impacted teeth with the maxillary sinus and the NPC during both orthodontic treatment and the extraction of impacted teeth.

With the growing use of the internet, the term cyberchondria—which refers to excessive or recurrent online searches for health-related information—is becoming increasingly prevalent. This study aimed to investigate the relationship between cyberchondria and oral health by utilizing the Cyberchondria Severity Scale (CSS) and assessing patients’ oral care status. This study was conducted using a questionnaire administered to dental patients. The questionnaire consisted of two parts. The first part collected data on patients’ demographic characteristics and oral care status. Oral care status was assessed based on self-reported oral hygiene practices and DMFT indices. The second part involved the administration of the Turkish version of the short-form CSS. After data collection, the responses were analyzed using the Independent Samples t-test, ANOVA, and Pearson correlation analysis. The study included 281 dental patients, of whom 54.1% were female and 51.6% were between 18 and 30 years of age. Among the participants, 31% were high school graduates. Half of the patients (50.9%) had high CSS scores, and 60.1% demonstrated a moderate level of oral care. Approximately one-third (33.1%) fell into the low DMFT category. Patients with high CSS scores tended to have better oral care, and this difference was nearly statistically significant (p = 0.054). The highest CSS scores were observed among patients in the low DMFT category (p = 0.313). Furthermore, no significant association was found between DMFT indices and CSS scores (p = 0.57). As digital technologies continue to advance, the frequency of online health information searches is also increasing. In the present study, patients with high CSS scores were found to have low DMFT category and better oral care status; however, these associations were not statistically significant. Nonetheless, the findings suggest that cyberchondria may have an influence on individuals’ oral hygiene behaviors.
