Evaluation of the Correlation Between Vertical Facial Discrepancies and Cervical Vertebral Fusion

Abstract

Background and aim: To date, the possibility of any correlation between pathological problems associated with cervical vertebral fusion and long facial pattern has been limitedly assessed. The aim of the present study was to find the correlation between the risk of fusion in cervical vertebrae and long facial pattern in adults. Materials and methods: In the present cross-sectional study, 80 lateral cephalograms with proper density and contrast were selected. The vertical facial dimension was analyzed to determine normal and long face patterns and to divide the samples into control and case groups, respectively. Cervical vertebrae were observed to detect the continuance of radiopacity between cervical vertebrae, which is considered as a risk of fusion. Data were transferred to SPSS software, and Pearson's chi-squared test was used to detect the correlation between cervical vertebral fusion and the vertical facial pattern. Results: The analysis of the data showed that the number of samples with fusion was higher in long face samples than in samples with normal vertical facial dimensions. Pearson's chi-squared test revealed a correlation between the vertical facial pattern and the risk of fusion in cervical vertebrae (P<0.001). Conclusion: According to the results, there is a correlation between an increase in the vertical facial dimension and the prevalence of cervical vertebral fusion.

Histological Evaluation of the Effect of Sildenafil and Pentoxifylline on Mandibular Fracture Healing in Rats

“…However, no previous study evaluated the effects of sildenafil and pentoxifylline on maxillofacial fractures. (42,(54)(55)(56) The current results revealed that pentoxifylline and sildenafil have positive effects on bone healing. Our findings regarding enhanced bone healing by sildenafil were in agreement with those of Yaman et al, Histing et al, and Çakir-Özkan et al (42,19,57) Aydin et al used pentoxifylline in a dosage similar to ours and showed that pentoxifylline enhances the formation of a hematoma, which is the first phase of bone healing.…”
