Sorption and solubility of biodentine new restorative material

Since water sorption of any restorative material can result in expansion of the restoration, which would be detrimental to the restoration, it is important to limit the amount of water absorbed. In addition, solubility of restorative materials is of concern, since inorganic ions can leach into the surrounding environment resulting in breakdown of the restoration. The aim of this study was to measure and compare water sorption and solubility values of Biodentine new direct restorative material with other conventional restorative materials

Three direct restorative materials were selected for this study: Biodentine [Septodont,France], composite [masterfill], GIC[Kemdent, UK]. Ten specimens were prepared from each restorative material [n=10] using a stainless steel mold of 15 mm in inner diameter and 1 mm in thickness. Each restorative material was prepared according to manufacturer's instructions. Water sorption and solubility of each specimen was calculated by weighting the samples before and after immersion in water for 15 days and desiccation. Data were analyzed with one way ANOVA and t-test at [0.05] level of significance

One way ANOVA that, there were statistically significant differences between the tested groups [P<0.05] in both sorption and solubility values

Within the limit of this study, Biodentine restorative material showed an intermediate sorption and solubility values between Kemdent GIC restorative and Master Fill composite and due to this result the material [Biodentine] is not recommended to be used as a final direct restorative material but recommended to be used as abase only

[Chondrosarcoma secondary to an exostosis of the distal femur [Report of a case with review of literature]]

The solitary osteochondroma or exostosis, is the most benign frequent tumor of the skeleton. It is the privilege of the young. It can be solitary or multiple in the framework of a multiple hereditary osteochondromata. The surgical indication is retained only when the tumour becomes symptomatic. The degeneration occurs in 1 to 25%, this rate increase when the great size tumors and the old patient. We report the case of a 25 years old patient, presenting a solitary osteochondroma of the left lower femoral metaphysis, with signs of malignancy in low grad secondary chondrosarcoma, suspected on elements of imagery and confirmed by the biopsy, this patient has underwent a monobloc large resection of the tumor, the bone and the adjacent muscle, with a favourable outcome after four years. This case illustrates the great limits ambiguity between the benign and the malign in the cartilaginous neoplastic pathology of the bone and the importance of the respect of algorithms of the skeleton tumors surgery in suspicious cases, because even if the histological examination of the operative model has not found the clear malignancy aspect, that does not eliminate the diagnosis of a chondrosarcoma, indeed, the histological distinction between an osteochondroma and a chondrosarcoma of low rank is very subtle

Induction of labor with sublingual prostaglandin E2 tablets in patients with intrauterine fetal death at term

to study the efficacy of sublingual prostaglandin E2 [PGE2] as a method of induction of labor in cases with intrauterine fetal death at term. the study group included 48 patients, 14 primigravidae and 34 multigravidae. Prostaglandin E2 was administered sublingually in the antenatal ward and the patients were monitored. The starting dose of 0.5 mg was doubled every 2 hours until uterine contractions were well established, or the maximum dose exceeded 9 mg, or any adverse effects occurred. the overall success rate of induction of labor was 89.6%, 85.7% in primigravidae and 91.2% in multigravidae. Vaginal delivery was achieved in 93.8% of primigravidae and 96.5% of multigravidae. Side effects were minor and dose related. Analgesia was required in 14.6% of cases. the use of PGE2 was associated with a high success rate and with few side effects
