However, the post-surgical fate of these miniplates remains a subject of contention among surgeons. Some advocate for their removal, while others suggest leaving them in place. This study aims to perform an extensive meta-analysis of pertinent studies to ascertain the destiny of miniplates employed in maxillofacial surgery and discuss the consequences of either their extraction or retention. To execute this meta-analysis, a search was conducted across number of databases, including PubMed, Google Scholar, ResearchGate, Embase, and Scopus. Keywords such as “titanium miniplates”, “screws”, “maxillofacial surgery”, “complications”, and “removal” were utilized to identify pertinent studies. The search was constrained to studies published between 1989 and 2022. The analysis encompassed only studies reporting outcomes related to minipla...

The aim of this study was to investigate variables that influence student's performance in a retrospective sample including all undergraduate students who entered in to Ajman dental college, between 1989 and 2010 (n=1141). Demographic and educational variables were used to predict performance in the overall curriculum and course groups. Standard ANOVA tests were used to examine the relationship between multiple indicators of admission criteria and dental college performance for the sixth cohort at the College of Dentistry, Ajman University. The admission criteria included the high school grade, English language and computer skills. Measures of dental college performance were the yearly and final dental college GPA/AGPA (Grade-Point-Average/Accumulative-Grade-Point-Average) and academic progress through the dental program. In general, most admission criteria were good indicators of dental college performance. Multivariate analyses indicated that students with higher grades in high school and English language and computer skill scores were more likely to achieve higher AGPA scores. The computer skill GPA and high school score were the most consistent determinants of dental college AGPA. Students with lower high school grade, computer and English language skill were more likely to remediate, to repeat an academic year, or to be dismissed from college.

If remain untreated for several years, it may be fatal. Hence, it is important to prevent and treat OSCC at an early stage. In this study the effect of aqueous and dry leaves extract of Ocimum sanctum was observed on Ca9-22 cell line, which is an OSCC cell line. For this, Ca9-22 cell line was cultured and maintained. After 24 h, the cells were treated with aqueous and dry leaves extract of Ocimum sanctum plant. Viability of the cancerous cells were studied by 3-(4, 5-dimethythiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay and neutral red uptake (NRU) assay. Minimum inhibitory concentrations (MIC), lethal concentration 25 (LC 25), lethal concentration 50 (LC 50) and highest permissive concentration (HPC) was calculated by probit computational method. Experimentally, the MIC value was 5 mg/L, whereas the HPC was 30 mg/L of the plant extract in aqueous state. For the dry extract the MIC was 5 mg/L whereas the HPC was 35 mg/L for both MTT and NRU assays. For MTT assay LC values: 7.41 (LC 25), 14.79 (LC 50) and 26.91 mg/L (LC 75) for aqueous extract and 12.58 (LC 25), 20.89 (LC 50), 29.51 mg/L (LC 75) for dry extract. For NRU assay LC values were 10.23 (LC 25), 14.79 (LC 50) and 20.89 mg/L (LC 75) aqueous extract, and 16.59 (LC 25), 23.44 (LC 50), 30.19 mg/L (LC 75) dry extract of the plant. From the above study it was concluded that, Ocimum sanctum have anti-cancerous activity. It can further be used for therapeutic purposes.

Panoramic radiographs of 200 adult patients with type 2 diabetes (90 male and 110 females) (age range 16-79 years; mean age 40.54 years) and 200 controls (age-match, free of systemic diseases) were examined on panoramic radiographs for any unusual radiopacity adjacent to or just below the intervertebral space between C3 and C4. Statistical analysis was carried out using chi-squared and Fisher exact tests. Carotid artery calcifications (CACs) were higher in diabetic patients compared with normal healthy control and the statistical difference between the two groups was significant (Chi-square test = 10.82, P = 0.001). Twenty-five (16 females, 9 males) diabetic patients showed CACs, Mean age of diabetic patients with calcification was 47.11 years. Further analysis of this group showed that 60% of patients with CACs were smokers, 48% had hypertension and 25% were obese. In conclusion, our study shows that in patients with diabetes mellitus CACs can be detected by panoramic radiography and the patients may benefit from a referral to physicians for further evaluation and necessary management. Materials and Methods A total of 200 diabetic patients (type II) (90 females, 110 males) who visited college of dentistry dental clinics between February 2011 to June 2012 and underwent dental panoramic radiographs for the diagnosis of dental lesions were selected for this study.

To compare the findings with similar studies and provide recommendations for the prevention and management of these fractures. Materials and methods: A 7-year retrospective study of maxillofacial fractures due to motor vehicle accidents was done. Results: We found that most of the accidents took place in December, and the majority of the patients were pedestrians (27%). Male to female ratio was 6:1, and patients in their third decade of life were the most affected (39%). The parasymphysis was the most prominently affected region (27.7%), followed by the orbital bone (18.6%). Open reduction surgery was done in 56% of the cases, and postoperative complications were found in 18.4%. Conclusions: Pedestrians were most commonly involved in the accidents. An increase in awareness, trauma centers, and better facilities would perhaps improve the management of such fractures.

This study examines whether personality profiles, personality factors, or clusters of personality factors are associated with academic success. Methods. The study includes all fifth-year dental students registered at the College of Dentistry, Ajman University, in 2019/2020. One hundred and seventy students were invited to complete personality and performance measures using the Big Five Inventory (BFI) scale; the weighted grade point average (GPA) was used to assess students' academic performance. Results. Of the 170 participants, 60% were female and 40% were male. Participants ranged in age from twenty-four to twenty-seven years, with an average age of twenty-four years. There was a relationship between personality scores obtained for the students and their subsequent academic performance. The broad conscientiousness, competence, achievement, and dutifulness predicted academic and clinical success. The prediction accuracy of conscientiousness was improved by the inclusion of dutifulness, self-discipline, and deliberation. Conclusion. This study confirms that the students' personality profile is a substantial predictor of academic performance and likely to help select future intakes of students, although a prospective study would be required for a definite answer to this question.

Also known as (SARS-CoV-2, SARS2 and 2019-nCoV), this epidemic is spreading widely across the globe like a wildfire. Recent reports Background: The pandemic outbreak of COVID-19 highlighting the zoonotic cross-over link in the present century has provoked an emergency worldwide. Recent experimental evidence supporting the proposition of ABO blood grouping and its susceptibility in certain blood group individuals has created interest among researchers to explore more. Aim: The aim of this study is to find the susceptibility of "ABO" blood group in COVID-19-positive cases. Objectives: Association of ABO blood group patterns with COVID-19-positive cases. Materials and Methods: A cross-sectional, observational study design was conducted among 728 confirmed positive COVID-19 admitted to the tertiary health care center in Maharashtra from June 01, 2020 to August 31, 2020. The inclusion criteria were COVID-19-positive cases confirmed by positive real-time reverse transcriptase-polymerase chain reaction test of severe acute respiratory syndrome coronavirus 2. We collected the demographic details, associated clinical symptoms and ABO blood groups from all the patients. The data collected were subjected to statistical analysis. Results: The most common blood group affected was B + (35.5%) followed by A + (26.10%), AB + (20.60%) and O + (11.18%) and the least common was AB-(0.96%), O-(1.51%), A-(1.65%) and B-(1.79%). Conclusions: ABO blood grouping can be used as one of the simplest yet efficient markers for COVID-19. Blood group B Rh-positive and A Rh-positive were the most prevalent blood group types in patients with COVID-19.

The risk outweighs the benefits in these unprecedented times if proper screening and inactivation of blood products are not performed. Pathogen reduction technologies incorporate various modalities for the inactivation of blood products mainly related to blood transfusion. Oral surgical procedures and periodontal surgeries use platelet-rich fibrin for various regenerative procedures that amplify the prognosis positively. The use of blood products for various treatments could result in contamination, a factor which should be significant attention. The objective of this study was to review the role of pathogen reduction technology in inactivating pathogens in blood products and its use in oral and periodontal surgical procedures. The literature presented in the study is from original studies from a period of 2000 to 2020 which...

Mucormycosis is a fatal fungal condition affecting immunocompromised patients caused by a group of mold mucoromycetes. Candida albicans (C. albicans) is an oral commensal present in almost 40-65% of healthy oral cavities in adults. Several cases of mucormycosis and oral candidiasis have been reported lately in COVID-19 patients, and it may elevate the associated risks of morbidity and mortality. Materials and Methods: Articles were taken from a period of 2020 to April 2021 using search sources such as Cochrane, PubMed, Fungiscope and Mycobank using keywords mucormycosis, Black fungus, oral candidiasis, white fungus, COVID-19, Sars-Cov-2. Discussion: The development of oral mucocutaneous lesions, such as mucormycosis and candidiasis in COVID-19 patients could be due to inhaling spores resulting in pulmonary and/or sinus congestion and prolonged mechanical ventilation in the ICU settings and the long-term use of broad-spectrum antibiotics respectively. The onset of candidiasis after the emergence of COVID-19 clinical signs and symptoms varied considerably and is reported within 1-30 days in most of the cases reported in the literature. Biofilms present on the denture surfaces are predisposing factors to oral candidiasis. We aim to summarize the limited data available regarding diagnosis, clinical presentation, and therapeutic approaches for the management of Mucormycosis and oral candidiasis in COVID-19 patients. Conclusion: Careful monitoring of oral lesions should be instituted through interdisciplinary telemedicine and teleconsultation to aid in primary diagnosis, thereby avoiding personal attendance during the pandemic. Dental practitioners should be included among the interdisciplinary teams for exhaustive intraoral examination and reduce the risk of morbidity and mortality.

This study confirms that the students' personality profile is a substantial predictor of academic performance and likely to help select future intakes of students, although a prospective study would be required for a definite answer to this question.

Also known as (SARS-CoV-2, SARS2 and 2019-nCoV), this epidemic is spreading widely across the globe like a wildfire. Recent reports Background: The pandemic outbreak of COVID-19 highlighting the zoonotic cross-over link in the present century has provoked an emergency worldwide. Recent experimental evidence supporting the proposition of ABO blood grouping and its susceptibility in certain blood group individuals has created interest among researchers to explore more. Aim: The aim of this study is to find the susceptibility of "ABO" blood group in COVID-19-positive cases. Objectives: Association of ABO blood group patterns with COVID-19-positive cases. Materials and Methods: A cross-sectional, observational study design was conducted among 728 confirmed positive COVID-19 admitted to the tertiary health care center in Maharashtra from June 01, 2020 to August 31, 2020. The inclusion criteria were COVID-19-positive cases confirmed by positive real-time reverse transcriptase-polymerase chain reaction test of severe acute respiratory syndrome coronavirus 2. We collected the demographic details, associated clinical symptoms and ABO blood groups from all the patients. The data collected were subjected to statistical analysis. Results: The most common blood group affected was B + (35.5%) followed by A + (26.10%), AB + (20.60%) and O + (11.18%) and the least common was AB-(0.96%), O-(1.51%), A-(1.65%) and B-(1.79%). Conclusions: ABO blood grouping can be used as one of the simplest yet efficient markers for COVID-19. Blood group B Rh-positive and A Rh-positive were the most prevalent blood group types in patients with COVID-19.

The risk outweighs the benefits in these unprecedented times if proper screening and inactivation of blood products are not performed. Pathogen reduction technologies incorporate various modalities for the inactivation of blood products mainly related to blood transfusion. Oral surgical procedures and periodontal surgeries use platelet-rich fibrin for various regenerative procedures that amplify the prognosis positively. The use of blood products for various treatments could result in contamination, a factor which should be significant attention. The objective of this study was to review the role of pathogen reduction technology in inactivating pathogens in blood products and its use in oral and periodontal surgical procedures. The literature presented in the study is from original studies from a period of 2000 to 2020 which...

Mucormycosis is a fatal fungal condition affecting immunocompromised patients caused by a group of mold mucoromycetes. Candida albicans (C. albicans) is an oral commensal present in almost 40-65% of healthy oral cavities in adults. Several cases of mucormycosis and oral candidiasis have been reported lately in COVID-19 patients, and it may elevate the associated risks of morbidity and mortality. Materials and Methods: Articles were taken from a period of 2020 to April 2021 using search sources such as Cochrane, PubMed, Fungiscope and Mycobank using keywords mucormycosis, Black fungus, oral candidiasis, white fungus, COVID-19, Sars-Cov-2. Discussion: The development of oral mucocutaneous lesions, such as mucormycosis and candidiasis in COVID-19 patients could be due to inhaling spores resulting in pulmonary and/or sinus congestion and prolonged mechanical ventilation in the ICU settings and the long-term use of broad-spectrum antibiotics respectively. The onset of candidiasis after the emergence of COVID-19 clinical signs and symptoms varied considerably and is reported within 1-30 days in most of the cases reported in the literature. Biofilms present on the denture surfaces are predisposing factors to oral candidiasis. We aim to summarize the limited data available regarding diagnosis, clinical presentation, and therapeutic approaches for the management of Mucormycosis and oral candidiasis in COVID-19 patients. Conclusion: Careful monitoring of oral lesions should be instituted through interdisciplinary telemedicine and teleconsultation to aid in primary diagnosis, thereby avoiding personal attendance during the pandemic. Dental practitioners should be included among the interdisciplinary teams for exhaustive intraoral examination and reduce the risk of morbidity and mortality.
