Abstract

Introduction: Many research proves that fluorapatite cement is one of the materials in dentistry that can restore and treat severe carious lesions. The current research was aimed to study the chemical reaction of calcium phosphate cement (CPC), calcite, and calcium fluoride as a base in fabricating the fluorapatite cement as an anti-caries agent. Methods: The type of research is a descriptive method.  The preparation of DCPA was initially performed by measuring 0.2g of DCPA powder which was prepared for 15 samples. Fluorapatite was fabricated using dicalcium phosphate anhydrous (DCPA), calcite (CaCO3) as the precursor to form carbonate apatite crystal, and calcium fluoride (CaF2). CaF2 will be mixed into sodium dihydrogen phosphate (NaH2PO4) with different percentages, 1%, 5%, and 10%. The samples were then incubated for 24 hours at 37˚C under 100% moisture condition. X-Ray Diffraction (XRD) characterization will be conducted to determine the phase composition and crystallinity of fluorapatite. In addition, the samples were analyzed with the Fourier Transform Infrared Spectroscopy (FTIR) examination to determine the crystal functional group. Results: All of the samples showed a satisfactory setting reaction. The XRD characterization results showed the formation of the crystal apatite phase at 32.43˚ and 32.83˚. The FTIR results indicated the stretching vibration of the fluoride compound at 1400 cm-1. The intensity formation of the apatite crystal phase at particular degrees was not as high as the standard hydroxyapatite data due to the incomplete formation of apatite crystal within 24 hours—the stretching vibration presence in the FTIR graph at 1400 cm-1 proven to be fluorapatite cement. Conclusions: Fluorapatite cement as an anti-caries agent can be fabricated through the mixing process of DCPA, CaCO3, and CaF2 powders with NaH2PO4 solution.

Abstract

Introduction: Burkitt’s lymphoma is a high-grade B-cell neoplasm and one of the most aggressive malignancies of lymphoid origins which found mainly in the paediatric population. The treatment options of this tumour are still limited. However, a new strategy for refractory tumour, phosphorothioate oligonucleotide antisense technique has watched with keen interest. This study was aimed to examine the effect of antisense p45Skp-2 (Skp-2 AS) suppressed migratory chemotactic and metastasis of oral malignant Burkitt’s lymphoma (Raji) cell through down-regulation of MTA-1 and E-cadherin. Methods: True experiment laboratory with post-test control group design was confirmed in this study. The efficiency of Skp-2 AS in the suppression of cell chemotactic migration was examined by Boyden chamber assay. To evaluate the inhibition of cell metastasis was conducted by decreasing MTA-1 expression protein. The expressions of MTA-1, E-cadherin and α-tubulin protein were investigated by Western blot analysis. Results: The results revealed that the number of chemotactic migration of Skp-2 AS treated Raji cell was significantly decreased when compared with that of sense p45Skp-2 (Skp-2 S) and scrambled control (SC) cells (P<0.05) followed by decreased expressions of MTA-1 protein and overexpression of E-cadherin. Interestingly, the expression of α-tubulin protein as an internal control was approximately similar in each transfectant cells. Conclusion: p45Skp-2 have an antitumor activity via suppression of migratory chemotactic activity and metastasis on oral Burkitt’s lymphoma cells through down-regulation of MTA-1 and induction of E-cadherin proteins targeting this molecule could represent a promising new therapeutic approach for this type of cancer.

Abstract

Introduction: Malaysia is situated in the southeast region of the Asian continent. Oral health services became prominent in the 1970s as programs related to oral health care were gradually introduced in schools. Various national epidemiological surveys were done to assess the prevalence of dental caries among children in Malaysia. This study was aimed to find out the DMF-t index level among school children based on their parents’ socioeconomic status by collecting consideration of education level and income of the fathers. Methods: This descriptive research with the survey technique was conducted at SJK (T) Klebang, Chemor, Perak, Malaysia. The DMF-t index of children in SJK (T) Klebang, Chemor, Perak was 0.2. Based on the questionnaire, the majority of fathers in Chemor, Perak were in the upper secondary education level with income ranging from RM 500 – RM 1000. Results: The Malaysian Oral Health Survey on 5-years old children showed that the caries prevalence was 75.5%. The mean of DMF-t was 5.57. An oral epidemiological study showed that 95.4% of 6-years old children in Peninsular Malaysia had carious primary teeth. This figure dropped to 88.6% in 1988, and by 1997 a further reduction to 80.6% was reported. DMF-t index consisted of the total number of Decayed, Missing and Filled teeth as well as a questionnaire on the socioeconomic background of the parents. Conclusion: The DMF-t Index of children in SJK (T) Klebang based on their father’s socioeconomic status is within the range of “Very Low” based on the DMF-t Index Scale.

Abstract

Introduction: Gold sea cucumber (Stichopus hermanii) is a marine organism that contains omega-3 and glycosaminoglycan for enhancing collagen needed in the healing process. This study was aimed to determine the effectiveness of gold sea cucumber extracts in accelerating the healing process of oral traumatic ulcer in Wistar rats, in terms of the correlation between collagen type I expression, ulcer diameter, and body weight loss. Methods: Twenty Wistar rats (Rattus norvegicus) was divided into four groups and treated with gold sea cucumber extracts with the concentration of 80%, 40%, and 20% in the form of 0.1 ml gel daily. The negative control group received no treatment. Ulceration of the lower lip of labial mucosa was induced by a burnisher. The animals were observed for 7 days, during which they were weighed and the ulcers diameter was measured. The rats were then sacrificed after 7 days of treatment. Histometric analysis of collagen type I expression was also performed. Data obtained were analysed for differences between the group with one-way ANOVA test and the correlation was analysed with the Pearson test. Results: The significant differences (p < 0.05) between treatment groups was found in the ulcer diameters and the collagen type I expression. The most decreased ulcer diameter and the highest collagen type I expression detected in the group of treatment with a concentration of 80% — no significant differences found in the weight loss between-groups (p > 0.05). Strong correlation was also found between the expression of collagen type I and diameter of ulcer (Pearson correlation = 0.599, p = 0.05), however, no correlation found between weight loss with the expression of collagen type I (Pearson correlation = -0.102, p = 0.66), and the ulcer diameter (Pearson correlation = 0.022, p = 0.92). Conclusion: Gold sea cucumber had a potential benefit to be used as a traumatic ulcer healing medicament. Water extract of gold sea cucumber able to accelerate traumatic ulcer healing by enhancing the production of collagen type I and reduce the diameter of ulcer. There is a strong correlation between collagen type 1 expression and diameter of ulcer, and a weak correlation found between body weight loss and collagen type I expression, also with reducing ulcer diameter.Keywords: Gold sea cucumber, Stichopus hermanii, healing process, traumatic ulcer.

Abstract

Introduction: Composite polymerization is a polymer molecule formation from monomeric molecules. To obtain good physical and mechanical properties of composite resin restoration, the dental composite resin must have the possibility of an optimal quantity of its monomer converted to the polymer during the polymerization reaction. The type, size, and content of the fillers in the composite are also essential factors in the polymerization process. A hardness test can be used to indirectly measure the hardness ratio of the upper and lower surfaces of the composite material (relative curing degree). The objective of this study was to analyze the differences in the hardness ratio of the upper and lower surface between LED-activated hybrid composite resin and nano composite resin. Methods: Thirty composite resin samples were randomly selected and divided into 2 groups. Group I was the hybrid composite resin group and Group II was the nano composite resin group. Samples were then formed into discs with a diameter of 6mm and a thickness of 2mm and polymerized using LCU LED with a light intensity of 800 mW/cm2 for 20 seconds. After 24 hours, the upper and lower surfaces of each sample were tested for three testing points using Vickers Hardness Tester. The data were then analyzed using the t-test. Results: The hardness ratio between the upper and lower surfaces (relative curing degree) of the hybrid composite resin and nano composite resin was 0.93 and 0.88 consecutively. Conclusion: There is any difference between the upper and lower surface hardness ratio of LED-activated hybrid composite resin and nano composite resin.
