Abstract

Cases of cleft lip and palate (CLP) in infants were many in Medan and surrounding areas.There were about 150 cases of infants with CLP in a year handled by Mitra Sejati Medan Hospital andGrandmed HospitalLubuk Pakan,butthetreatmentgiven was only surgical treatment,while the follow-up care,which isthefabricationofartificialpa-late or feeding plate before or after surgery,cannot be facilitated.Until now CLP further treatment cannot be done becausetheparentsdonotknowthetreatmentand most of them came from groups with low socio-economic level andthefabricationof feedingplaterequiredhigh costs.To overcome this problem,we held communityserviceby fabricating feeding plates as feeding aids for babies with CLP.The method used to achieve this goalofserviceis collectingdatafrompatientswithCLPinthetwohospitals,generalexaminationbypediatrician,makingtheimpression of the oral cavity to create the working cast,making outline design,doing thewaxpatternandfeeding plate fabrica-tioninthe laboratory using hard and soft acrylic materials combination.The insertion of feedingplatesisperformed at the hospital and evaluated whether the baby can drink milk normally using a bottle. Body weight changes are evaluated every month until the baby is declared ready for surgery.

Abstract

Introduction: Heat cured acrylic resin is frequently used denture base material whereby transverse strength is one of the mechanical properties that must be observed. A rough surface absorbs water, reduces strength of denture bases, thus polishing should be done. Pumice is the most abrasive material used in dentistry. Eggshell and tooth-paste can be used as alternative abrasive materials. This study aims to determine the differences in value of trans-verse strength of HCA resin once polished using pumice, eggshells, and toothpaste. Method: This laboratory ex-perimental study using sample sized 65x10x2.5 mm with 30 samples in total for 3 groups. Transverse strength was measured using Universal Testing Machine. The data were analyzed using one-way Anova. Result: The comparison ratio of transverse strength between HCA resin after polishing with pumice, eggshells and tooth paste is 93.63 : 118.42 : 105.91 MPa. It shows there were significant differences in transverse strength between groups with sig-nificant value p was 0.001 which less than 0.05. Conclusion: The value of transverse strength varies according to polishing material used. Eggshell has the highest transverse strength value compared to pumice and toothpaste.

Abstract

Heat-cured acrylic resin is easily fractured and can be prevented by adding reinforcing materials of duck eggshell powder. Furthermore, it can be used as a biocompatible reinforcing material due to the high content of CaCO3. This study aims to determine the effect of adding 2.5% and 5% duck eggshells as reinforcement for the denture base with heat-cured acrylic resin on the transverse strength. The method is an  laboratory experiments with a post-test only control design conducted on January 2022. The samples were made by adding a reinforcing agent of 2.5% and 5% heat-cured acrylic resin powder’s weight in a mould sized 65 x 10 x 2.5 ± 0.5 mm with 11 samples in each group. The curing process was executed at a temperature of 70°C for 90 minutes before increasing to 100°C for 30 minutes, and the transverse strength of acrylic resin was measured using the Universal Testing Machine. The sample tested using univariate analysis with the results of the average transverse strength in the control group 66.59 ± 1.88 MPa, after adding 2.5% duck eggshell 72.61 ± 3.05 MPa and 5% duck eggshell 86.14 ± 4.09. The one-way ANOVA and LSD tests showed significant results with p-value = 0.001 (p < 0.05) and 0.001 (p <0.05). The highest transverse strength value of heat-cured acrylic resin was found in the 5% duck eggshell group, followed by 2.5%, and lastly, the control group.

Abstract

Laminate veneer is a treatment in prosthodontic that is aesthetically pleasing and requires minimal preparation that can be fabricated with indirect resin composite, which is durable and low-cost, though this material has poor color stability. Due to the increasing consumption of black tea and apple juice, there was a need for this study to be taken out. This study aims to determine the effect of consumption of black tea and apple juice on colour stability. Indirect resin composite specimens were fabricated 20 mm in diameter and 1.5 mm in thickness and divided into 3 groups (n = 10). Specimens were immersed in 3 types of solutions: black tea, apple juice and aquadest as control. The color of specimens was measured before and after immersion using a color spectrophotometer. Statistical analysis was performed with univariate test, Mann-Whitney U test, Independent T-test, one-way ANOVA and LSD test. Mean delta E (ΔE) value for black tea is 1,381 ± 0,938 and ΔE = 6,803 ± 1,757 in apple juice. Black tea and apple juice reduced the color stability of indirect resin composite significantly with p = 0,001 (p < 0.05). The effect of immersion in both drinks differed significantly with p = 0,001 (p <0.05). Apple juice experienced the greatest reduction in color stability, followed by black tea, and lastly the control group. The difference in the effect of immersing black tea and apple juice was due to the difference in pH and major acid content.
