Oral Tissue Engineering Progress and Challenges
Muhammad Sohail Zafar,Zohaib Khurshid,Khalid Almas 한국조직공학과 재생의학회 2015 조직공학과 재생의학 Vol.12 No.6
Tissue engineering is a multidisciplinary science. The progress of tissue engineering for dental tissues is promising and various dental soft and hard tissues have been regenerated successfully in vitro using stem cells. Prior to their applications practically, there are a number of challenges and unanswered questions that need to be resolved for further progress. It is expected that in next two to three decades, the field of dentistry will be changed significantly by the availability of innovative tissue engineered products in dental office. The objective of this review paper is to highlight the progress of tissue engineering for various dental hard and soft tissues such as enamel, dentin, alveolar bone, periodontium, oral mucosa, and salivary glands. In addition, the challenges in the progress of tissue engineering and future expectations have been discussed.

Purpose: Sinus elevation procedures have become a routine and reliable way to gain bone volume in the edentulous maxilla for dental implant placement. Presence of bony septations and pathology in the maxillary sinus often cause complications leading to graft or implant failure or both. The aim of this study was to retrospectively evaluate the prevalence of pathology, direction of the septa, and sinus width measured at 2 mm, 5 mm, and 10 mm from the sinus floor in maxillary sinuses using cone-beam computed tomography (CBCT). Materials and Methods: Seventy-two sinuses from 36 random preoperative CBCT scans referred for implant therapy were retrospectively evaluated for the number, prevalence, and direction of bony septations and presence of pathology. Width of the sinus was also measured at 2 mm, 5 mm, and 10 mm from the sinus floor to account for the amount of bone available for implant placement. Results: Maxillary sinus septa were found in 59.7%. Presence of a single septum was noted in 20 sinuses (27.7%), followed by two septa in 17 sinuses. The most common direction of the septum was the transverse direction. Retention pseudocyst and mucosal thickening were the most commonly seen abnormality/pathology. Conclusion: Based on the high prevalence of septa and sinus pathology in this sample, a preoperative CBCT scan might be helpful in minimizing complications during sinus augmentation procedures for dental implant therapy.
