The Aesthetic

For a long time, different approaches to minimize the dimensional ridge alteration following tooth extraction have been described even though none of them was capable to avoid alveolar bone loss. The Socket-Shield Technique (SST) seems to be an alternative for alveolar bone preservation in dental extraction planning. This technique conventionally uses a flapless approach and the buccal root portion retention to prevent bone loss. This case report describes the SST with an early implant placement in a patient who presented the nonrestorable tooth # 15 due to the extensive cavity. After six months of the implant placement a porcelain-fused-to-metal crown was fabricated and screwed into the implant with a satisfactory esthetic and functional result. The SST is a non-invasive and effective approach to tooth extraction and rehabilitation, especially in the aesthetic zone. Approximately two-year follow-up shows a satisfactory aesthetic maintenance.

Objectives: The purpose of this study was to evaluate vertical alveolar bone loss 3 months after tooth extraction when a technique of ridge preservation was applied using a particulate demineralized freeze-dried bone allograft 300 - 500 µm associated with platelet concentrates (platelet-rich-fibrin) in the form of gel and membranes. Material and Methods: A retrospective radiological clinical study was conducted on 56 patients for whom 95 extractions had been performed immediately followed by alveolar filling. Among the patients, 17 were smokers and 16 were provided with an immediate removable temporary prosthesis after extractions. Vertical bone loss was measured radiologically by panoramic X-ray before extractions and by a computed tomography scan 3 months after, at the level of mid-buccal bone wall, by two independent observers. For statistical analysis, Student’s t-test was performed to compare the mean bone loss between mono- and pluri-radicular teeth and to compare the mean bone loss between tobacco users versus non users and finally to compare the mean bone loss between individuals that had provisional removable prosthesis and those that had not. Results: Three months after tooth extraction, the mean of vertical loss of the mid-buccal bone wall was 0.72 (SD 0.71) mm (5.53% SD 5.19). No significant difference between bone loss at mono-radicular and pluri-radicular teeth (P = 0.982) was observed. There was no significant correlation between tobacco habits and bone loss (P = 0.2), nor between provisional removable prosthesis and bone loss (P = 0.786). Conclusion: These results indicate a good potential for the technique using Demineralized Freeze-Dried Bone Allograft 300 - 500 µm and platelet concentrates in alveolar bone preservation.

Objective: This study was to determine OPG and RANKL expression after hydroxyapatite (HA) scaffold from crab shells (Portunus pelagicus) application in tooth socket of Cavia cobaya. Methods: This study was a post-test only control group design. Twenty four Cavia cobaya was divided into 4 groups. The lower left incisor was extracted and given a combination of HA and gelatin scaffold. Experimental animals were sacrificed on the 7th and 14th day. The amount of OPG and RANKL expression was calculated under a light microscope at 1000x magnification. The statistical analysis was done by One Way ANOVA Test and Tukey HSD. Results: Compared to other groups, the lowest and the highest level of OPG and RANKL were in P14 group. Conclusion: HA scaffold from crab shells (Portunus pelagicus) can increase OPG expression and decrease RANKL expression in the process of regenerating alveolar bone after tooth extraction.

Background: The main oral health problem in Indonesia is the high number of tooth decay. Tooth extraction is the treatment often received by patients who experience tooth decay and the wound caused by alveolar bone resorption. Bark of Mangifera casturi has been studied and proven to contain secondary metabolite which has the ability to increase osteoblast’s activity and suppress osteoclast’s activity. Purpose: The purpose of this study was to analyze interleukin-1 beta (IL-1β) and bone morphogenic protein-2 (BMP-2) activities during bone remodeling after Mangifera casturi’s bark extract treatment. Method: This study was laboratory experimental research with randomized post-test only control group design. The Mangifera casturi bark was extracted using 96% ethanol maceration and n-hexane fractionation. This study used 40 male Wistar rats which are divided into 4 groups and the tooth extraction was performed on the rats’ right mandible incisive tooth. The four groups consisted of 6.35%, 12.7%, 25.4% extract treatment group, and a control group. Wistar’s mandibles were decapitated on the 7th and 14th day after extraction. Antibody staining on preparations for the examination of IL-1β and BMP-2 expressions was done using immunohistochemistry. Result: There was a significant difference of IL-1β and BMP-2 expressions in 6,35%, 12,7%, and 25,4% treatment groups compared to control group with p<0.05. Conclusion: Mangifera casturi’s bark extract was able to suppress the IL-1β expression and increase the BMP-2 expression during bone remodeling after tooth extraction.
