Assessment of the content and quality of YouTube videos related zygomatic implants: A content-quality analysis.

INTRODUCTION: This study aimed to evaluate the content and quality of YouTube videos of zygomatic implants. METHODS: According to Google Trends (2021), "zygomatic implant" was the most preferred keyword related to the topic. Therefore, in this study "zygomatic implant" was used as a keyword for the video search. Demographic characteristics such as the number of views, likes/dislikes, comments, video duration, number of days after upload, uploaders, and target audiences of the videos were evaluated. To evaluate the accuracy and content quality of videos (available from YouTube), the video information and quality index (VIQI) and global quality scale (GQS) were used. Statistical analyses were performed using the Kruskal-Wallis test, Mann-Whitney U test, chi-square test, Fisher's exact chi-square test, Yates continuity correction, and Spearman correlation analysis (p < 0.05). RESULTS: A total of 151 videos were searched; 90 met all inclusion criteria. According to the video content score, 78.9% of the videos were identified as low content, 20% as moderate, and 1.1% as high content. There was no statistical difference between the groups in video demographic characteristics (p > 0.001). Conversely, information flow, accuracy of information, video quality and precision, and total VIQI scores were statistically different between the groups. The moderate-content group had a higher GQS score than the low-content group (p < 0.001). The videos were mainly uploaded (40%) from hospitals and universities. Most videos were targeted toward professionals (46.75%). Low-content videos had higher ratings than the moderate- and high-content videos. CONCLUSIONS: Most YouTube videos on zygomatic implants showed low-content quality. This implies that YouTube is not a reliable source of information on zygomatic implants. Dentists, prosthodontists, and oral and maxillofacial surgeons should be aware of the content of video-sharing platforms and take responsibility for enriching video content.

Knowledge, beliefs, attitude, and practices of E-cigarette use among dental students: A multinational survey.

BACKGROUND: E-cigarette use is a trend worldwide nowadays with mounting evidence on associated morbidities and mortality. Dentists can modify the smoking behaviors of their patients. This study aimed to explore the knowledge, beliefs, attitude, and practice of E-cigarette use among dental students. MATERIALS AND METHODS: This multinational, cross-sectional, questionnaire-based study recruited undergraduate dental students from 20 dental schools in 11 countries. The outcome variable was current smoking status (non-smoker, E-cigarette user only, tobacco cigarette smoker only, dual user). The explanatory variables were country of residence, sex, age, marital status, and educational level. Multiple linear regression analysis was performed to explore the explanatory variables associated with E-cigarette smoking. RESULTS: Of the 5697 study participants, 5156 (90.8%) had heard about E-cigarette, and social media was the most reported source of information for 33.2% of the participants. For the 5676 current users of E-cigarette and/or tobacco smoking, 4.5% use E-cigarette, and 4.6% were dual users. There were significant associations between knowledge and country (P< 0.05), educational level (B = 0.12; 95% CI: 0.02, 0.21; P = 0.016) and smoking status (P< 0.05). The country of residence (P< 0.05) and smoking status (P< 0.05) were the only statistically significant factors associated with current smoking status. Similarly, there were statistically significant associations between attitude and country (P< 0.05 for one country only compared to the reference) and history of previous E-cigarette exposure (B = -0.52; 95% CI: -0.91, -0.13; P = 0.009). Also, the practice of E-cigarettes was significantly associated with country (P< 0.05 for two countries only compared to the reference) and gender (B = -0.33; 95% CI: -0.52, -0.13; P = 0.001). CONCLUSION: The knowledge of dental students about E-cigarette was unsatisfactory, yet their beliefs and attitudes were acceptable. Topics about E-cigarette should be implemented in the dental curriculum.

What are the Risk Factors for Mortality Among Patients Who Suffer Le Fort III Fractures?

PURPOSE: Le Fort III fractures are the most severe subtype of the Le Fort fractures and are associated with adverse clinical outcomes. The purpose of this study was to identify risk factors for mortality among patients who suffer Le Fort III fractures. MATERIALS AND METHODS: A retrospective cohort study was completed using the 2016-2018 National Inpatient Sample. Patients with isolated Le Fort III fractures were selected. Patients who incurred bone fractures or organ injuries outside the head and neck were excluded. There were multiple, heterogenous predictor variables. The primary outcome variable was mortality. Relative risk was used to determine independent risk factors of mortality. Statistical significance was deemed for P values less than .05. RESULTS: The final sample consisted of 559 patients (mean age, 45.9 years) who suffered a Le Fort III fracture, of whom 15 patients (2.68%) died. Most patients were male (82.7%) middle-aged adults (42.9%) of White race (66.5%) within the lowest income quartile (31.7%) that lived in large metro areas (54.9%). Relative to males, females were nearly 62 times more likely to die (P < .01). Relative to privately insured subjects, uninsured subjects were 23 times (P < .05) more likely to die. Relative to weekday admissions, weekend admissions increased the risk of mortality by 8 times (P < .05). Cranial vault fractures (odds ratio, 7.24; P < .05) and upper cervical fractures (odds ratio, 63.27; P < .05) were risk factors for mortality. Relative to males, females were at an increased risk for mortality (relative risk [RR] 7.14, 95% confidence interval [CI] 2.60, 19.61). Skull base fracture (RR 2.99, 95 CI 1.04, 8.63), cranial vault fracture (RR 3.04, 95 CI 1.07, 8.65), subdural hemorrhage (RR 2.98, 95 CI 1.10, 8.05), subarachnoid hemorrhage (RR 6.73, 95 CI 2.34, 19.35), and injury of blood vessels at neck level (RR 13.24, 95 CI 2.46, 71.16) were each risk factors for mortality. CONCLUSIONS: Intracranial injury was not a risk factor for mortality. Instead, cranial vault fractures and skull base fractures increased the risk for mortality. In addition, uninsured patients and female patients were each at an increased risk for mortality.

Patterns of craniomaxillofacial trauma among helmeted cyclists.

BACKGROUND/AIM: The head and face are prone to injury in bicycle accidents and helmets are proven to be helpful in decreasing injuries to some extent. The aim of this study was to determine whether certain craniomaxillofacial regions are at increased risk of injury (fracture) during bicycle accidents among helmeted cyclists. MATERIALS AND METHODS: This retrospective cohort study was conducted using data from the National Electronic Injury Surveillance System (NEISS). Data concerning craniomaxillofacial injuries as a result of cycling accidents between 2019 and 2020 were reviewed. The primary predictor variables were the craniomaxillofacial region and a craniofacial bone. The co-variates included patient characteristics (age, gender, race) and injury characteristics (location, season). The primary outcome variable was a fracture. Logistic regression was used to determine any independent risk factors for a fracture. RESULTS: Five hundred patients reported helmet use at the time of injury. Fractures of the face region were 75 times (p < .01) more likely than the head region. No particular craniofacial bone was at greater risk of fracture relative to the maxilla. Adults (OR 24.0, p < .01) and seniors (OR 38.6, p < .01) were each at greater risk for fracture relative to children. CONCLUSIONS: The facial region was at increased risk of fracture relative to the head during a bicycle accident. Adults and seniors were at increased risk of suffering craniofacial fractures relative to children.

Risk factors for increased length of hospital stay among young pediatric patients who suffer facial fractures.

BACKGROUND/AIM: It is not known whether the mechanism of facial trauma influences the associated length of hospitalization. The aim of this study was to determine whether the mechanism of injury influenced the length of hospital stay (LOS) among pediatric patients who sustained facial fractures. MATERIALS AND METHODS: This retrospective cohort study was completed using the Kids' Inpatient Database (KID). The primary predictor variable was the mechanism of injury. The primary outcome variable was LOS. Linear regression was used to determine independent predictors of increased/decreased length of stay. A p-value of less than .05 was considered statistically significant. RESULTS: The final sample consisted of 2865 subjects aged 12 years or younger who had suffered facial fractures. The most common mechanism of injury was motor vehicle accidents (MVA) (58.6%). Facial fractures due to MVA added 1.20 days (95% CI, 0.02, 2.38; p < .05) when compared to those due to a fall. CONCLUSIONS: MVA significantly prolonged the LOS among young pediatric patients who sustained facial fractures, reflecting the exceptional amount of force involved. Having a chronic condition was also a significant factor for longer LOS. Four or more fractures also led to a longer LOS.

Oral health practices and self-reported adverse effects of E-cigarette use among dental students in 11 countries: an online survey.

OBJECTIVES: E-cigarette use has become popular, particularly among the youth. Its use is associated with harmful general and oral health consequences. This survey aimed to assess self-reported oral hygiene practices, oral and general health events, and changes in physiological functions (including physical status, smell, taste, breathing, appetite, etc.) due to E-cigarette use among dental students. METHODS: This online, multicounty survey involved undergraduate dental students from 20 dental schools across 11 different countries. The questionnaire included demographic characteristics, E-cigarette practices, self-reported complaints, and associated physiological changes due to E-cigarette smoking. Data were descriptively presented as frequencies and percentages. A Chi-square test was used to assess the potential associations between the study group and sub-groups with the different factors. Statistical analysis was performed using SPSS at P < 0.05. RESULTS: Most respondents reported regular brushing of their teeth, whereas only 70% used additional oral hygiene aids. Reported frequencies of complaints ranged from as low as 3.3% for tongue inflammation to as high as 53.3% for headache, with significant differences between E-cigarette users and non-users. Compared to non-smokers, E-cigarette users reported significantly higher prevalence of dry mouth (33.1% vs. 23.4%; P < 0.001), black tongue (5.9% vs. 2.8%; P = 0.002), and heart palpitation (26.3%% vs. 22.8%; P = 0.001). Although two-thirds of the sample reported no change in their physiological functions, E-cigarette users reported significant improvement in their physiological functions compared to never smokers or tobacco users. CONCLUSION: Dental students showed good oral hygiene practices, but E-cigarette users showed a higher prevalence of health complications.

Happiness among dentists: a multi-scale, multi-national study from 21 countries.

OBJECTIVES: The extent to which dentists are happy with their profession and their life has not been well studied. The present study aimed to explore the level of happiness, satisfaction with life and psychological well-being among a sample of dental professionals from 21 countries. MATERIALS AND METHODS: The sample comprised 2,200 dentists from 21 countries. Three scales - Subjective Happiness Scale (SHS), Satisfaction With Life Scale (SWLS), and Affect Balance Scale (ABS) - were used to measure the subjective responses. Data related to demographic and social characteristics were recorded. Mann-Whitney and Kruskal-Wallis tests were used as appropriate. Scales were correlated, and multiple linear regression analyses were employed to identify the independent determinants of SHS, SWLS and ABS. Data were analysed using the SPSS software program; a value of P <0.05 was considered significant. RESULTS: The overall mean scores of SHS, SWLS and ABS were 18.53 ± 5.06, 23.06 ± 6.25 and 1.26 ± 2.40, respectively, with significant differences found across countries: dentists working in Croatia, Peru and Serbia recorded the highest scores, unlike dentists practicing in Yemen, Syria, and Iraq, who recorded the lowest scores. There were significant, moderately positive correlations between the various scales: SHS and SWLS: r = 0.535, P < 0.001; SHS and ABS: r = 0.58, P < 0.001; and SWLS and ABS: r = 0.533, P < 0.001. Country of practice, age, qualification and monthly income were the significant independent predictors of SHS, SWLS and ABS. CONCLUSION: Country of residence and social characteristics were associated with dentists' responses regarding their feelings and subjective well-being.

Accessory mental foramen.

CONTEXT: Accessory mental foramen is a rare anatomical variation. Even so, in order to avoid neurovascular complications, particular attention should be paid to the possible occurrence of one or more accessory mental foramen during surgical procedures involving the mandible. CASE REPORT: A 3-dimensional computed tomography (3D-CT) scan of a female patient revealed an accessory mental foramen on the right side of her mandible. CONCLUSION: A 3D-CT scan should be obtained prior to mandibular surgeries so that the presence of accessory mental foramen can be detected, and so that the occurrence of a neurosensory disturbance or hemorrhage can be avoided. Although this anatomical variation is rare, it should be kept in mind that an accessory mental foramen may exist.

iNOS expression in oral and gastrointestinal tract mucosa.

It is known that the overproduction of nitric oxide (NO) by nitric oxide synthase (NOS) occurs during the progression of various inflammatory diseases in intestinal tract. NOS inhibitors or inducible nitric oxide synthase (iNOS) gene expression inhibitors should be considered as potential anti-inflammatory agents, as NO synthesized by iNOS is related to various pathophysiological processes including inflammation. In order to understand the relationship between iNOS and pathological reactions such as the inflammatory process and malign transformation clearly, the existence and amount of constitutive expression should be determined. It is crucial to comprehend the harmful and protective amounts of iNOS expressions in order to clarify the relationship between iNOS and pathological processes. Evidently, only after this inspection is it possible to utilize iNOS as a marker and treatment instrument during the diagnosis and treatment of malign transformation and the inflammatory process.

[The results of combined treatment (surgery and postoperative radiotherapy) for tongue cancer and prognostic factors]. / Dil kanserinde kombine tedavi (cerrahi ve radyoterapi) sonuçlari ve prognostik faktörler.

OBJECTIVES: We evaluated the results of surgical treatment and postoperative radiotherapy and prognostic factors in patients with primary tongue carcinoma. PATIENTS AND METHODS: The study included 60 patients (31 males, 29 females; median age 54 years; range 22 to 82 years) who underwent surgery and postoperative radiotherapy for oral tongue cancer. Tumor staging based on the AJCC-1997 criteria was as follows: stage I (n=1), stage II (n=21), stage III (n=12), and stage IVA (n=26). Surgery included hemiglossectomy (n=46, 76%), partial (n=13, 22%) and total (n=1, 2%) glossectomy. Neck dissection was performed in 47 patients (78%). Radiotherapy dose was generally 6000 cGy/30 fr. The median follow-up was 51 months (range 5 to 180 months). RESULTS: The five-year overall and relapse-free survival rates were 50% and 47%, respectively. Survival at five years was 70% for stage I-III, and 20% for stage IVA. Most of the relapses occurred in the first two years after treatment. Recurrences were encountered in 31 patients (52%). The median survival after recurrence was eight months (range 1 to 53 months). In multivariate analyses, significant prognostic factors for overall survival and locoregional control were tumor size, stage, N stage, extracapsular lymph node spread, and total duration of radiotherapy. Complications were within acceptable limits. CONCLUSION: Postoperative radiotherapy should be standard for patients with stage III and IVA tongue cancer.

Management of the perforations due to miniplate application.

Microdimensioned osteosynthesis using miniplates has been common practice in maxillofacial surgery. However, tooth injury during the application of the miniplates have been reported in few papers. In this case, a 32-yr-old female patient, whose two teeth were necrosed because of the perforation during screw insertion was presented. The reason of the perforations during the rigid internal fixation was the lack of radiographic assessment because of the pregnancy. Maxillary right first premolar and maxillary left canine were perforated and necrosed because of the screw insertion. The necrosed teeth were detected 1 yr after the rigid internal fixation. The root canals of nonvital teeth were filed using step-down approach. Cold lateral condensation of gutta-percha was used to fill the canals. Six-month recall visits were scheduled and there was no problem after 2-yr follow-up period.

Schizophrenia and dental management: review of the literature.

Schizophrenia is a brain disease that manifests itself with multiple signs and symptoms involving thought, perception, emotion, and behavior. Despite the fact that these manifestations combine in various ways to create considerable diversity among patients, the cumulative effect of the illness is always severe and usually long lasting. Schizophrenia is diagnosed in the presence of certain positive and negative psychotic symptoms, as well as psychologic and cognitive deterioration. In addition to history, medical and psychiatric examinations are used to rule out other possible diagnoses. Schizophrenia is not a rare disorder, and it affects approximately 1% of the general population. Many of these individuals require several hospitalizations, and the financial cost of schizophrenia is substantial. In this article, clinical features of schizophrenia are reviewed, and the important consequences from the perspective of dental practitioners are highlighted.

Alzheimer's disease and dental management.

Alzheimer's disease (AD) is a major disorder of old age and the most common cause of dementia. Dementia is loss of intelligence, memory, and cognitive functions. It is usually associated with aging, but there are many possible causes. Older adults are the most rapidly growing segment of the population. To maintain lifelong good oral health, the elderly need regular dental care. This review of AD summarizes the causes, epidemiology, diagnosis, and dental management of patients with AD.
