Background. Eyes are an important component of the face and vital organs of vision. Eye loss can be caused by congenital defects, trauma, or tumor. Loss of an eye produces physical abnormalities that pose a psychological burden on the patient, as well as visual function damage. An ocular prosthesis is an artificial maxillofacial prosthesis to replace the lost eye. Case summary. A 54-year-old man consults at the Prosthodontics Specialist Universitas Airlangga Dental Hospital for an eye prosthesis. The patient did not have the right eyeball since birth. Soft tissue around the eye is normal, including the palpebral muscles. Case management. An impression was made using a custom tray and alginate in the defect area, followed by filling the impression with gypsum type 3 to get a working model, from which a wax model is made and adjusted to the patient. After that, sclera and ocular acrylic prostheses are made on the basis of an adjusted wax model. The prosthesis is then polished and colored according to the contralateral eye. Then the prosthesis is delivered to the patient. Conclusion. The hollow custom-made eye prosthesis can be considered in the treatment of anophthalmia. It is able to improve the patient's psychological and emotional status.
Objectives This study aimed to determine some of bone molecular expressions and its possible bone remodeling pathway between diabetes mellitus (DM) and osteoporosis model in the mandibular bone of Wistar rats. Materials and Methods Twenty-seven female Wistar rats were divided randomly into control and treatment groups. Treatment groups were injected with streptozotocin intraperitoneally to induce DM (P1) and underwent bilateral ovariectomy to generate osteoporosis (P2). All groups were terminated after 12 weeks. Immunohistochemical and hematoxylin–eosin staining were performed to determine the expression of Runt-related transcription factor 2 (RUNX2), Osterix, vascular endothelial growth factor (VEGF), receptor activator of nuclear factor κB ligand (RANKL), osteoprotegerin (OPG), tartrate-resistant acid phosphatase (TRAP), and observed the osteoblast and osteoclast. Statistical analysis was performed using one-way analysis of variance. Results The lowest mean of RUNX2 and VEGF expression was found in the P2 group. The lowest mean of Osterix expression was found in the P1 group. Both P1 and P2 groups of osteoblast/osteoclast ratio were decreased. There were no significant differences in the expression of TRAP between all groups; however, increased expression of RANKL/OPG ratio was only found in the P2 group. Conclusion DM and osteoporosis induce changes in the bone remodeling pathway which are represented by a decrease in osteoblast biomarkers and an increase in osteoclast biomarkers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
