Abstract

Mesenchymal stem cells (MSCs) have generated a promise as a potential source of cells for tissue engineering application due to their instrinsic ability to self-renew and differentiate into functional cell types. With their ability to differentiate into multiple cell phenotypes, mesenchymal stem cells offer the potential to regenerate entire tissue from a single cell source. Recent studies have demonstrated that MSCs were successfully used for bone repair, cartilage repair and soft tissue repair. This paper briefly outlines the biological characteristics of Mesenchymal stem cell and its application in tissue engineering field.

Abstract

The efficacy of biomaterials-either as replacements for damaged tissues, or as a temporary scaffolds for the manufacture of engineered tissues and organs- relies on the ability of the material surface to regulate cell adhesion. Adhesion plays a critical role to regulate proliferation, differentiation and phenotypic behaviour, therefore consequently impact tissue development and function. Cell adhesion to biomaterials may be characterized in terms of specific and nonspecific interactions. Specific interaction entail cell receptor recognition, whereas nonspecific interaction encompass noncovalent attractive forces. This paper gives a review of the phenomena occuring in cell/material interaction and particularly the role of cell adhesion

Abstract

Tooth extraction can cause alveolar ridge resorption that affect the use of the denture, so it requires augmentation to improve the contour of the alveolar ridge. Hydroxyapatite is used as alveolar ridge augmentation material in Indonesia, they are imported at high prices and availability limited. In Indonesia, especially the area of ​​East Java Jember district Puger produced natural gypsum raw materials that can be developed and utilized as hydroxyapatite. This study aims to determine how the process of synthesis and characterization Hydoxyapatit using FTIR XRD analysis of Gypsum Puger Jember as alveolar ridge augmentation material. Methods of synthesis of hydroxyapatite research conducted by hydrothermal technique by reaction between gypsum hydroxyapatite Puger with DHP (diammonium hydrogen phosphate), then the result of the reaction was analyzed by XRD and FTIR testing compared with HA 200 Japan as a comparison. The results of the analysis we found the same patterns between Gypsum hydroxyapatite Puger with HA 200 Japan as standard. Conclusion The study has managed to synthesize gypsum puger into hydroxyapatite / Puger gypsum hydroxyapatite (HAGP). Characterization HAGP performed by XRD and FTIR that test results are the same, or there is a similar pattern with HA 200 Japan (standard), so HAGP is one of the bioceramics materials that can be used as an alternative material alveolar ridge augmentation in order to use denture can be managed properly.

Abstract

Patients with visual impairment experienced debris, calculus and a high index of oral hygiene. Low salivary flow anddifficulty in cleaning the oral cavity in patients with visual impairment caused high accumulation of plaque that causesa decrease in the pH of saliva. Low pH of saliva affects the balance of the composition of inorganic email. Calcium isthe largest inorganic content of the email, thus dissolving calcium email can be an indication of enameldemineralization. This study aimed to determine the solubility of calcium in saliva of blind patients, and salivary pHrelationship with the solubility of calcium. This experimental laboratory study used saliva taken from 8 blind patientsand artificial saliva as a medium of enamel pieces soaking for 24 hours. Dissolved calcium levels were measured byatomic absorption spectrophotometer. The results showed that the solubility of calcium in the saliva of blind patientsgreater than the control group (p<0.05). Pearson correlation test demonstrate the relationship between salivary pHand solubility of calcium enamel, so the lower the pH the greater enamel calcium dissolution. It was concluded that themagnitude of the solubility of calcium enamel due to decreased of salivary pH.
