ABSTRACT
Introduction: In many oral procedures that involve the implants, hair implantations, "Platelet-Rich Fibrin Membrane (PRF)" is commonly applied. The advantages are many. In this study, the mechanical resistance of PRF under resistance pull on a longitudinal axis was assessed and compared. Material and Methods: For the current in vitro study, 60 volunteers donated each 10 ml of their blood and hence a total volume of 600 ml of blood was procured that was analyzed for the current study. The total volume was grouped to three groups where they receive three resistance centrifugation forces of "F-200,600,800 m/s²." In each group, 20 samples were tested for each level of the G-resistance. Each group was further divided as two subgroups of different times of wait, where they were centrifuged at baseline time and after a stand of 30 minutes. On universal testing equipment, the PRF membranes were mechanically tensioned in order to determine each membrane's resistance force. These values were compared for any statistical variance using appropriate statistical tools keeping P < 0.05. Results: Any applied force had no statistically significant effect on the centrifugation duration for membrane resistance. When the resistance was applied for the PRP samples immediately after they were procured, no significant variation was seen at all the grades of the centrifugation forces; consequently, the T30 group showed a statistically significant variance for the centrifugation forces applied (P = 0.04), with the highest value when the greatest force was applied. According to the results, the centrifugation waiting period could be determined based on the application requirement. Conclusion: For immediate membrane usage, the centrifugation had no effect on resistance; however, after 30 minutes, a membrane with greater resistance was produced by applying more force.
ABSTRACT
Radicular or periapical cysts are one of the most commonly occurring odontogenic cysts of the jaws. The present article reported a case of a 12-year-old female with the chief complaint of swelling and pain on the right lower back tooth region. The radiographic examination revealed the presence of a well-defined radiolucency surrounded by a corticated border with respect to the right mandibular 1st, 2nd and 3rd molar. The case was managed by complete enucleation under general extraction with the extraction of right mandibular 1st, 2nd and 3rd molar. The success of the surgery was apparent by the uneventful healing during the follow-up period and evidence of complete healing after 1-month follow-up. Early diagnosis of the lesion would have lead to a less aggressive treatment plan.
