A case report presents the experience of diagnosis and management of Unicameral Bone Cyst(UBC) of midshaft Humerus. The lesion had a pathognomonic radiologic appearance of Unicameral Bone Cyst and diagnosis was histologically confirmed. We treated operatively by open curettage with auto graft bone augmentation with external fixator and significant improvements was noted in post-operative period. On basis of analysis of treatment results open curettage with auto graft bone augmentation with external fixator. if required, effective procedure Obtaining good functional results and shorter period of treatment

Background: Surgical treatment stills the most effective treatment for a giant cell
tumor of bone (GCTB). The aim of the present study was to evaluate the outcomes
of surgical treatment of giant cell tumor in proximal end of tibia by curettage and
bone cement. Patients and methods: This clinical trial study was conducted on 18
patients underwent surgical treatment of giant cell tumor in proximal end of tibia
by curettage and bone cement at orthopedic department, Zagazig University
Hospitals. Their age was ranged from 22 to 41 years. Two thirds (66.7%) of the
studied group were females and one third (33.3%) of them were males (2:1). After
completion of the investigations, staging of the tumor was recorded using
Campanacci's radiological grading method. Postoperative follow up was done to
assess the functional outcome and to detect the presence of complications. Results:
The present study showed that, 83.3% had companaccis grade I and grade II
(16.7%). 88.8% underwent cement and hydrogen peroxide and 11.2%underwent
cement, hydrogen peroxide and internal fixation. Regarding MSTS, only 33.3% of
them had intermediate pain, all patients had enthused emotional acceptance and
66.7% had unlimited walking ability and 22.2% had intermediate gait. Post
operative follow up showed the recurrence rate was zero (0.0%) after a follow up
time (11.2±1.04) months ranged from 9 to12 months. There was only 11.1% of
patients had superficial infection. Conclusion: Surgical treatment of a giant cell
tumor of bone using Cement filling after extended curettage is provide a good
oncological outcome and joint preservation. Curettage with adjuvants is a feasible
first choice treatment option for GCTB with Cement filling does not increase the
recurrence rate.

Marginal adaptation is a critical property of treatment . These summaries marginal fit in the light potential disrupting factors And underlying mechanisms in provisional fixed prosthesis treatment. Marginal gap at tooth restoration and should be sealed properly . Microbial leakage is the most important factor influencing long term success of restoration and causing interfacial contamination of bacteria through ingress of oral fluids.Complications of marginal integrity can cause micro/nano size gaps resulting in plaque accumulation, sensitivity, and secondary caries.marginal integrity remains an important predictive tool for clinical outcome at restoration margins. ultrasonic instrumentation for root debridement, on changes in periodontal clinical parameters.Microleakage is a cause of restorative treatment failure and allows the passage of bacteria, oral fluids, molecules from the restoration and cavity walls. The vibration of scaler tips is the main effect to remove the deposits from the dental surface and there will be a constant flushing activity of the lavage used to cool the tips and cavitational activity which cause disruption of the weak and unattached subgingival plaque.
