METHODS: A total of 426 dental panoramic radiographs of 5-15-year-old Malaysian children were included in the study. The mean age error and absolute age error for all the methods were calculated and their usability analyzed.
RESULTS: The Nolla, Willems. and Demirjian methods overestimated the dental age with a mean of 0.97, 0.54, and 0.54 years, respectively, while the Cameriere and Haavikko methods underestimated by 0.41 and 1.31 years, respectively. The Cameriere method was highly precise and accurate in the population of Malaysian children, whereas the Haavikko and Demirjian methods were the least precise and accurate.
CONCLUSIONS: The Cameriere method of dental-age estimation is highly valid and reliable for Malaysian population, followed by the Willems and Nolla methods.
OBJECTIVE: The systematic review is aimed at evaluating the value of PRF in different areas of surgery.
DATA SOURCES: A systematic review of articles sourced from MEDLINE-pubmed (2008-2017(July)) was done. Additional articles were searched through GOOGLE SCHOLAR and SCIENCE DIRECT. Search terms such as Platelet rich fibrin; Platelet rich fibrin, surgery; Platelet concentrate; second generation concentrate; Applications of PRF in surgery were used.
STUDY SELECTION: Systematic reviews, Randomized control trials, Pilot studies and Case reports were included. Non English articles, in-vitro and animal studies were excluded.
DATA EXTRACTION: Independent sourcing of articles by 3 authors using a set of predefined criteria.
DATA SYNTHESIS: Out of the 25 articles covering various surgical procedures that met the inclusion criteria, positive outcomes were noted in most. Although categorization into one specific type of study was not done, the overall success rate with PRF usage was 78%.No differences between test and control groups were observed in 2 studies and 3 studies showed no significant improvements with the usage of PRF.
LIMITATIONS: The systematic review did not categorize the study designs while evaluating success rates which might be considered as a shortcoming as case reports were also included.
CONCLUSIONS: The future propositions are vast and point towards innovative applications of this bio-material possibly in transplant and burn cases if a method of obtaining large amounts can be devised. However since we rely on evidence-based results, further long term studies are needed in distinct areas of applications to decisively prove its effectiveness.
CASE REPORT: We present a case report on management of an electrosurgery induced osteonecrosis involving maxillary alveolus of left premolars.
DISCUSSION: Inadvertent contact of the electrosurgery tip on bone can result in necrosis making it necessary to remove the sequestrum and graft the defect. Platelet rich fibrin in combination with bone grafts have been well documented to provide successful periodontal regeneration.
CLINICAL IMPLICATIONS: Our aim of presenting this report is to create awareness among the health care providers regarding electrosurgical injuries. To our knowledge, this is the first time platelet rich fibrin has been used in the management of intraoral electrosurgical injury. Combining bone grafts with platelet rich fibrin is a good alternative as it can be done with relative ease and predictable outcome.
