Knowledge and performance of senior Dental Students of Zanjan University of Medical Sciences (Iran) regarding the principles of oral biopsy and cytology

Background: The present study was designed to evaluate the knowledge and attitude of the sixth-year dental students of Zanjan University of Medical Sciences regarding the principles of oral biopsy and cytology. Materials and Methods: This cross-sectional study was concocted on 70 of the final year dental students of Zanjan University of Medical Sciences in 2021. The data was collected in the census method. The data collection tool was a researcher-made questionnaire, the first part of which included demographic information (n=3) and the second part related to students’ knowledge (n=10) and performance (n=4) of the principles of biopsy and oral cytology. Before distributing the questionnaire, its validity and reliability were confirmed. The data was entered into SPSS24 software and Spearman’s rank correlation coefficient and Independent sample t-test were used to analyze the data. Results: The mean and (±SD) of the age of the students was 24.84±1.72 years and 31 (44.3%) were men. The mean (±SD) scores of students’ knowledge and performance of biopsy were 4.41 (±1.12) and 0.68 (±0.60), respectively. Also, students’ knowledge and performance regarding oral cytology were 0.51 (±0.63) and 0.47 (±0.58), respectively. There was no statistically significant relationship between gender and age variables with knowledge and performance levels in the biopsy and cytology sections (P-Value>0.05). Conclusion: Our study showed students’ knowledge and performance of oral biopsy was moderate, while their knowledge and performance of oral cytology was very poor, therefore, it seems necessary to provide solutions to increase students’ knowledge and performance.

Clinical Findings and Dental Manifestations Associated With Microcephalic Osteodysplastic Primordial Dwarfism Type II: A Case Report

Background: Microcephalic Osteodysplastic Primordial Dwarfism type 2 (MOPD II) is a rare untreatable genetic disorder characterized by severe prenatal and postnatal growth retardation, microcephaly, bird-headed face (receding forehead and chin, a beaklike nose, and prominent eyes), skeletal abnormalities, abnormal dentition, abnormal hair and skin changes, high-pitched nasal voice, and an increased risk for insulin resistance and cerebrovascular disease. MOPDII is caused by mutations in the pericentrin gene and is inherited in an autosomal recessive manner. This study aims to report a MOPD II child patient.  Case Presentation: A seven-year-old girl genetically diagnosed with MOPD II has been presented in this case report. Clinical, radiological, and laboratory findings with emphasis on oral features have been reported, and her dental problems management has also been described. Conclusions: MOPD II patients have a shorter life expectancy. The main health complications which need regular care include vascular changes of the central nervous system, diabetes mellitus, renal problems, blood pressure, cardiac pathologies, and hematologic profile. MOPD II patients have a high risk of caries because they consume soft and cariogenic foods due to microdontia, oligodontia, and an incompetent masticatory system. On the other hand, dental treatment for such patients can be very challenging. MOPD II cases and their families should be aware of the importance of oral hygiene and routine dental follow-ups
