Defek telinga unilateral ataupun bilateral dapat disebabkan oleh berbagai faktor, diantaranya trauma, kelainan pertumbuhan, atau prosedur pengangkatan kanker. Kondisi ini akan mempengaruhi psikologis pasien karena telinga merupakan organ vital yang membentuk estetika wajah. Salah satu perawatan rehabilitasi pada defek telinga adalah dengan pembuatan protesa telinga. Tahapan penting dari pembuatan protesa telinga adalah mendapatkan cetakan yang akurat untuk membuat pola malam. Teknik pencetakan dalam pembuatan prothesa telinga diantaranya metode reversible hydrocolloid dengan sendok cetak malam, irreversible hydrocolloid dengan sendok cetak kaku dan metode pencetakan tiga lapis. Keunggulan teknik pencetakan tiga lapis adalah mudah di lakukan dan akurasi hasil pencetakan yang baik. Tujuan laporan kasus ini adalah mengaplikasikan teknik pencetakan tiga lapis dalam pembuatan prothesa telinga.Perawatan dilakukan pada seorang pria berusia 14 tahun yang mengalami defek kongenital telinga dextra (unilateral). Langkah pertama dalam pembuatan prothesa yaitu pencetakan telinga normal dan defek, dilanjutkan pembuatan pola malam dan basis protesa, kemudian tahap try in pola malam, processing silikon, dan insersi. Prosedur pencetakan telinga dengan teknik tiga lapis yaitu mengaplikasikan irreversible hidrocolloid pada regio post aurale (lapisan pertama), regio pra aurale, permukaan internal, (lapisan kedua), dan permukaan luar telinga (lapisan ketiga). Hasil pencetakan telinga dengan teknik tiga lapis adalah tiga lapisan irreversible hidrocolloid yang solid dan mudah untuk dipisahkan sehingga menjamin akurasi hasil pengecoran. Kesimpulan laporan kasus ini adalah teknik pencetakan tiga lapis dapat diaplikasikan dalam pembuatan prothesa telinga.ABSTRACTS: Triple Layer Impression Method For Auricular Prosthesis. An unilateral or bilateral auricular defect can be caused by several factors including trauma, congenital malformation or surgical removal of neoplasm. These condition will affect patient psycologic because ear is a vital part of facial aesthetic. One of rehabilitation care of auricular defect is an auricular prosthesis. Important stage of making auricular prosthesis is to obtain accurate impression to make wax pattern. Impression technique including method of reversible hydrocolloid with wax collar, irreversible hydrocolloid with rigid tray and triple layer impression method. The excellence of the triple layer impression technique are easy to do and accuracy of good impression result. The aim of this case report is to apply triple layer impression method in the making of auricular prosthesis. The treatment was done in 14 years old male patient with chief compain of congenitally defect of external dextra ear. First step of making auricular prosthesis is making an impression of defect area and opposite ear, making prothesa basis and wax pattern, try in the wax pattern, sillicone processing, and insertion the prothesa. Triple layer impression method was done in three step, first the impression material was injected to post aurale region (first layer), than injected to internal surface of ear (second layer). Subsequently, the third layer of impression material was partially filled into the tray and external surface of ear.The result of triple layer impression method in the making of auricular prosthesis is triple layer of solid irreversible hydrocolloid but separatable completly. Conclusion of this case report is the triple layer impression method is suitable for making an auricular prosthesis.

Background: Composite resin is filling material that used in dentistry fieldbecause of good aesthetic. Use of fiber as reinforced composite resin (FRC)begins to be developed because it has a lot of functions, such as increasestrength, stiffness, material hardness from fracture, and decrease shrinkage.Fiber composite resin has syntetic characteristic and needs chemical processalso has an expensive price. Therefore, natural fiber is easier to find, cheaper and can be developed as an alternative substitute of syntetic fiber. One of the natural alternative is sisal fiber. This study aims to know the effect of volume fraction of sisal fiber to composite resin flexural strength with sisal fiber concentration 1%, 2%, 3%, 4%.Method: This study was true experimental with post test only control groupdesign which divided into 4 groups RK+FS 1% (K1), RK+FS 2% (K2), RK+FS3% (K3), RK+FS 4% (K4). The data was analized using one way ANOVA assayand Post Hoc with significant degree 5%.Results: Mean of flexural strength sum K1=50,87 MPa, K2=42,96 MPa,K3=33,94 MPa, K4=24,32 MPa. Result of one way ANOVA assay showed valuep=0,000. Result of further assay Post Hoc showed K1 with K2 p=0,002, K1 withK3 p=0,000, K1 with K4 p=0,000, K2 with K3 p=0,001, K2 with K4 p=0,000, K3with K4 p=0,000.Conclusions: Concluded that there is good effect of sisal fiber volume fractionto composite resin flexural strength. Flexural strength RK+FS 1% has higherstrength than RK+FS 2%,3%,4%. Sisal fiber could become a natural fiberalternative in dentistry restoration material.

Background: Candida albicans is main cause of fungal infections in denture users. Prevention is needed by soaking dentures using a disinfectant. Chitosan is an alternative disinfectant emulsion because it is biodegradable, biocompatible, and does not cause discoloration. This research objective is to determine the effect of chitosan emulsion on the number of C.albicans on base plate thermoplastic nylon. Method: This is a true experimental study using post-test only design by using 25 base plates divided into 5 groups namely treatment I, treatment II, treatment III, positive and negative control. Plate was incubated in C.albicans suspension for 24 hours in McFarland and 10-3 series dilution. The plates was rinsed with aquadest, then soaked with 0.3% chitosan emulsion, 0.8% chitosan emulsion, 2% chitosan emulsion, 0.2% chlorhexidine gluconate, and aquadest for 15 minutes. The attached C.albicans colony in the plate was released to the SDB by using centrifuge device, then proliferated on the SDA and incubated (24 hours). The results of the C.albicans colony were counted visually by using a colony counter. The number of Candida albicans colonies data were analyzed using One-Way ANOVA and then Post Hoc Tukey HSD test. Result: The results showed that there were significant mean differences between each group (p
