Abstract

The use of Glass Ionomer Cement (GIC) has some limitation, such as water sensitivity which leads to formation of microleakage due to shrinkage and brittle. Incorporation of 0.04 wt% bioactive glass nano silica (BAG) with GIC enhances its bioactivity to forming hydroxycarbonate apatite (HCA) leading to preventing of marginal gap formation. The objective this study was To determine the difference of microleakage means value between GIC and GIC which has been added by BAG from bagasse. In this study making BAG from bagasse, than choose the samples (24 bovine) randomly and grouping them to be 4 groups, which are group 1, GIC; group 2, GIC+Vaseline, group 3, GIC+BAG; group 4 GIC+BAG+Vaseline. All of the samples are supposed to be preparation, placed of the restoration, and stored in the aquadest then methylen blue 1% in sequence at 37oC until 24 h. The microleakage means value is decided by scoring system depend on the penetration of methylen blue 1% at occlusal wall and gingival wall. The microleakage means value on GIC+BAG is smaller than GIC, but their differences were not significant.

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.

Abstract

Root caries is common in the elderly, usually detected late, involving enamel, cementum, and dentin below the cementoenamel junction (CEJ). Remineralisation is used to treat it when cavitation has not occurred. Bioactive glass triggers remineralisation by forming hydroxycarbonate apatite (HCA) at an early stage. Injectable paste preparations are needed to overcome these problems. The use of hyaluronic acid and carrageenan polymers supports the physical and mechanical properties of the paste preparation. The purpose this research to analyse the formation of HCA on the tooth root surface by administering bioactive glass (BAG) injection paste with the addition of seaweed carrageenan. This study was a laboratory experimental study with three research groups, namely treatment group 1 (BAG paste and hyaluronic acid), treatment 2 (BAG paste, hyaluronic acid and carrageenan), and control group (BAG without polymer). All groups were immersed in artificial saliva, incubated at 37oC for six days and then tested by Scanning Electron Microscope (SEM) to see the formation of HCA and FTIR. HCA was quantified by a scoring method according to predetermined score criteria. SEM showed HCA formation in both treatment groups, not the control group. There is HCA formation on the tooth surface by administering BAG injection paste with seaweed carrageenan.
