Abstract

Objective: The aim of this research is to evaluate the value of the histological score based on a histological record compared to the histometry for monitoring cranial bone defect healing. Methods: We designed a case -control study with a control and a study group. For a number of 60 CD1 mice representing the study group, a bone defect in the cranial bone was surgically induced and grafted with bone grafts obtained by tissue engineering. Bone grafts were obtained using embryonic stem cells seeded on a scaffold obtained from the red deer antler, and osteogenic basal and complex medium was used as differentiation medium. For other 30 CD1 mice representing the control group, a bone defect in the cranial bone was induced and left to heal without grafts. The regeneration process was assessed after 2 and 4 months using the histological healing scoring system and histometry. Results: The healing score was statistically significantly correlated with the defect size obtained by means of histometry (p<0.001). The evaluation of the parameters comprised in the healing score shows that regeneration of the bone diastasis was the most advanced in the group sacrificed at 4 months after plasty, which employed embryonic stem cells, a complex osteogenic differentiation medium and deer antler as scaffold. Conclusion: histological method based on a histological score is a valuable quantification system of bone regeneration comparable to histometry. Clinical Relevance: This study proves that the presented histological score can help the clinician in the process of bone regeneration evaluation.

Abstract

Purpose: The present study aims radiological aspects of the occurrence of osteonecrosis of the jaw age groups both in receiving i.v bisphosphonates tratment Imaging assessment of bisphosphonates therapy-induced osteonecrosis of the jaw it is important to differentiate neoplastic invasion, osteomyelitis, osteoradionecrosis induced by radiation or bone related pathology of general diseases.

Material and method: We conducted a retrospective clinical study including 22 patients (8 men and 14 women) with various stages of osteonecrosis of the jaw.

Results: Radiological examinations using CBCT are required in all therapeutic approach of osteonecrosis of jaw cases providing accurate informations of position, dimension and the link with anatomical structures.Our study showed that the prevalence of osteonecrosis of mandibular growth is higher in women than in men and the risk of osteonecrosis of the jaw in appearance is depending on age factor witch occurs more often between age 52-59 and 73-80 years old.

Conclusion: The multitude of complications due to treatment with bisphosphonates bind to an early and specialized therapeutic approach. Radiological examinations is a first choice in the detection and early diagnosis of osteonecrosis of the jaw, patients requiring a permanent supervision by the physician and dentist.
