ABSTRACT
BACKGROUND: Stem cells of mesenchymal origin have good proliferative capacity when compared to other stem cell types. Dental pulp stem cells (DPSCs) are a variety of mesenchymal cells obtained from the pulpal tissue of teeth and are abundantly available and easy to obtain. DPSCs facilitate and improve the formation of new bone using different bone graft scaffolds. This present study aims to evaluate and compare the osteogenic potential of DPSCs on alloplastic and xenogeneic bone grafts. MATERIALS AND METHODS: Hydroxyapatite and beta-tricalcium bone graft and bovine bone graft were used in a triplicate manner in the laboratory. DPSCs were obtained from the pulpal tissue of extracted third molars in the laboratory. The cytotoxicity, osteogenic potential, and difference in the rate of proliferation of mesenchymal cells on the biomaterials were assessed. RESULTS: Darker purple staining was seen in the case of hydroxyapatite/beta-tricalcium bone graft on MTT colorimetric assay stating that there was an increase in cell viability in hydroxyapatite/beta-tricalcium bone graft as compared to the bovine bone graft. Hydroxyapatite/beta-tricalcium bone graft showed more osteogenic potential as compared to the bovine bone graft as a higher degree of red staining was seen in Alizarin staining. CONCLUSION: Higher cell viability and higher osteogenic proliferation and differentiation were seen on the hydroxyapatite/beta-tricalcium bone graft compared to the bovine bone scaffold.
ABSTRACT
Biopsy is the gold standard in the diagnosis of oral pre-malignant and malignant cases. In borderline cases, false-positive or false-negative results can grossly affect treatment planning, leading to a bad prognosis. C-reactive protein (CRP) has been linked to poorer outcomes for patients with oral pre-malignant and malignant lesions. To validate the histopathological finding and ultimately direct treatment, the study aims to correlate pre-treatment levels of CRP in oral pre-malignant and malignant lesions. This will provide a biomarker to assess the prognosis in such cases. Our study investigated 53 patients, out of whom 35 were males and 18 were females. A CRP analysis was performed on each patient. The automated immunoturbidimetric method was utilized to quantify CRP levels. The CRP values of pre-malignant lesions ranged from 2.46±1.79 mg/L, while the malignant group's levels ranged from 7.90±3.18 mg/L. The findings imply that plasma CRP levels may be a potential indicator of elevated cancer risk and that pre-diagnostic CRP concentrations are linked to the later development of oral cancer.
ABSTRACT
This article presents a clinical case of a central giant cell granuloma (CGCG) resembling a periapical lesion of endodontic origin. A 39-year-old, otherwise healthy male patient was referred to the department of oral and maxillofacial surgery for its diagnosis and subsequent management. The patient presented with an asymptomatic, progressively increasing intraoral swelling associated with the mandibular left para-symphysis region. On radiographic evaluation, a unilocular radiolucent lesion involving 33-34 teeth was noted. An incisional biopsy presented a giant cell lesion, following which surgical curettage was done. Histopathological examination was in accordance with the diagnosis of CGCG. Therefore, it is imperative for clinicians to accurately diagnose and rule out similarly presenting lesions.
ABSTRACT
Benign osseous tumors of mesodermal origin that are included within the group of fibro-osseous lesions include cemento-ossifying fibromas (COFs). The fibrocellular component of these diseases originates from the periodontal ligament, which deposits bone and cementum encased in fibrous tissue. It typically appears in the mandible and presents as a solitary, nonaggressive, slowly developing, asymptomatic, expansile lesion, rarely occurring in the maxilla. The only intervention that proved to be successful in producing excellent outcomes and that may be regarded as a final therapeutic option is the complete surgical removal of COFs. Presenting herein is a case report describing a painless and expansile mass in the left mandibular region, histopathologically diagnosed as COF.
ABSTRACT
Context Over the past 60 years, several researchers have conducted extensive studies on the use of dexamethasone to reduce the postoperative complications of lower third molar surgery, namely, pain, edema, and trismus. In this study, we compared the oral and intramuscular methods of dexamethasone administration. Purpose The aim of this research was to assess pain, edema, and trismus in the postoperative period following the surgical removal of the lower third molar using 8 mg of dexamethasone given orally or by intramuscular injection. Method A split-mouth technique was employed for the study, in which each of the two bilaterally impacted mandibular third molars was removed one at a time, separated by at least two weeks. There were 26 participants in this experiment. Two groups were created from the research sample: group A (injection dexamethasone) and group B (tablet dexamethasone). The pain was assessed on the first, second, and third postoperative days. On the first, third, and seventh postoperative days, the parameters, such as edema and trismus, were evaluated. Results As per our study, in terms of edema and trismus, there was less of a statistically significant difference between the two interventions at all time points. While the pain score had a significant difference between both interventions. Conclusion Hence, we conclude that oral dexamethasone is an effective alternative to intramuscular dexamethasone. Oral dexamethasone is comparatively simple, less invasive, painless, and easy for the surgeon and for apprehensive patients, and it offers a cost-effective solution for the suffering often associated with the extraction of impacted lower third molars.
