Clinical and radiographic findings are non-specific hence histopathological evaluation forms the basis for definitive diagnosis. This is a case of a 27-year-old female with a complaint of pain and swelling in her lower right back tooth region for one month. The swelling caused gross facial disfigurement with no secondary changes. Intraorally the growth involved both buccal and lingual sulci causing mobility of involved teeth. Radiographically severe periodontal bone loss was noted surrounding 47. Incisional biopsy was taken and sent for histopathological evaluation. The histopathological examination revealed lobular pattern of growth filled with sheets of round to polygonal cells showing pleomorphism and bizarre hyperchromatic nuclei along with a typical mitotic figures surrounded by densely packed spindle-shaped cells. In some areas chondroid matrix deposition with lacunae containing atypical chondrocytes was evident. Ki-67 IHC was done which showed 10 positivity. Hence the lesion was diagnosed as Grade I Chondrosarcoma. It must be differentiated from chondroblastic osteosarcoma as it bears close resemblance with it. The treatment is completely different for both entities. Chondrosarcoma is chemo-resistant and radioresistant whereas osteosarcoma is a highly chemosensitive tumor. Surgical resection is the treatment of choice in chondrosarcoma hence hemi-mandibulectomy was carried out in this case.","PeriodicalId":155332,"journal":{"name":"RGUHS Journal of Dental Sciences","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135914281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such ridges require a combination of techniques in placing implants. One such technique is the ridge split technique which helps the expansion of the ridge with or without greenstick fracture of cortical plates. Before placing implants the width of the alveolar ridge can be effectively restored utilising the modified ridge splitting approach employing autologous bone grafts. This case report describes the ridge splitting and placement of a dental implant in the left maxillary central region followed by guided bone regeneration. Ridge expansion was done in relation to 21 and osteotomy was prepared to the desired depth. After proper treatment planning implant measuring 3.5 mm in diameter and 11.5 mm in length was placed. Four months later final cementation was done with PFM crown. The ridge split technique with the immediate implant placement resulted in minimal resorption of alveolar bone along with maximum expansion of the bone. The sequential surgical and restorative techniques were combined into one successful protocol whose steps are well elaborated in this case report.","PeriodicalId":155332,"journal":{"name":"RGUHS Journal of Dental Sciences","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135913147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Access opening was done using an extracted tooth and the pulp fixed in formalin solution. After sufficient fixation decalcification was done followed by processing and histological examination. The radicular dentin thickness was measured at 3 reference points and the mean value was compared with histological parameters to assess for any changes.Results Results revealed that various histological changes were observed in the pulp. The mean dentin thickness when compared with various histological parameters revealed varying results. Inflammation and edema did not corelate with changes in dentin thickness whereas fibrosis presence of pulp stone pulp vessels and odontoblastic integrity showed a positive correlation but were not statistically significant.

The stresses may cause micromovement that jeopardises the healing process in early stages. These stresses aggravate as the implant goes deeper into the bone and somewhat accounts for increased friction and torque. Excess torque at the insertion time may lead to bone compression which if crosses its physiologic limit may lead to a bloodless field i.e. ischemia following necrosis or sequestrum formation which in turn will cause implant failure. This is termed as compression necrosis. Too much torque levels may result in high levels of strain transmitted to adjacent bone. The crestal area around the implant is mainly comprised of cortical bone which has minimum blood supply and is exposed to extreme strain making it more vulnerable to bone necrosis and which is paramount to the failure of implant. An attempt has been made to review the physiologic effect of alveolar bone on compression necrosis the mechanism and histopathology behind compression necrosis factors leading to compression necrosis like excess torque strain macrogeometry of implants implant design and methods to avoid compression necrosis.","PeriodicalId":155332,"journal":{"name":"RGUHS Journal of Dental Sciences","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135912894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Informed consent was obtained from the patient. All the clinical as well as radiographic parameters were assessed. Open flap debridement with intramarrow penetration and placement of PRF was done for these patients and were followed up for nine months.Results All the patients were consistent with the follow up till nine months. Intergroup comparison of Probing Pocket Depth PPD and Clinical Attachment Level CAL showed significant difference with p lt0.05.
