Application of advanced platelet-rich fibrin for through-and-through bony defect during endodontic surgery:Three case reports and review of the literature

BACKGROUND The use of advanced platelet-rich fibrin(A-PRF)membranes for guided bone and tissue regeneration in through-and-through defects after endodontic surgery was explored in three cases.CASE SUMMARY Herein,three patients presented to the endodontic clinic suffering from apical periodontitis,associated with large bone resorption and related to previously endodontically treated teeth.Periapical surgery was indicated in these cases and the osteotomy site was covered by A-PRF membrane.Cone-beam computed tomography(CBCT)was used to assess the cases before and after the surgery.CONCLUSION Four months post-surgery,the recall CBCT scan showed complete obliteration of the osteotomy with newly formed bone.A-PRF membrane showed promising results and was an advantageous addition to surgical endodontic treatment.

Dental Pulp Stem Cells, a New Era in Regenerative Medicine: A Literature Review

Objectives: The aim of this review is to explain the role of Dental Pulp Stem Cells (DPSCs) in repairing or regenerating damaged tissue/organs for both systemic and oral diseases and, in addition, review the differentiation, isolation of dental pulp stem cells and their applications in regenerative medicine. Materials and Methods: An electronic search was done using Cohchrane, PubMed and Google Scholar. Out of 310 articles, only 25 articles have been selected to be included in this review because it is directly related to the topic and they are matching the inclusion criteria of this review: “Language: English” and “Year: 2006-2016”. Results: DPSCs have been widely used as a mesenchymal stem cells source due to easy accessibility and less invasive harvesting. DPSCs could be used for pulpal regeneration, tooth reconstruction, endocrinology, neurology, angiogenesis and vasculogenises. The most common application of DPSCs in the dental field is pulp regeneration. Conclusion: Stem cell-based therapy holds a great promise to solve health problems from both systemic and oral diseases. Studying in DPSCs grows rapidly;however, there are still questionable issues needed to be optimized and answered such as the variable biological capacity of DPSCs.

Dietary Habits and Oral Hygiene Practice amongst Dental Students at the College of Dentistry, Princess Nourah University

The aim of the present study was to assess the dietary habits and oral hygiene practice of dental students in a new dental school. A self-administered structured closed-ended questionnaire on demographic characteristics, medical history, oral hygiene and dietary habits was distributed to dental students. Results showed that One third of students indicated that they don’t consume low pH beverages (soft drinks) at all, while 48.9% drink a soft drink or two a day. Students took varying amount of time to consume their drinks. The majority of participants consumed citric juices, fruits and/or pickles at least once a day. 91.3% of students use either soft (41.8%) or medium (49.5%) toothbrush. Only a fifth (16.9%) of the students brush their teeth after drinking soft drinks and 58.2% brush their teeth after vomiting. In conclusion, young adults need to be aware about their dietary habits & oral hygiene, and also a proper dental health program needs to be applied.
