Covid-19 is an infectious disease that attacks the human respiratory system that can cause respiratory infections, ranging from the common cold to serious illnesses, this disease is caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) virus. The process of Covid-19 transmission can occur through direct contact, droplets that are spread through coughs or sneezes from infected people and aerosols in dental care procedures. Aerosols can be generated from dental procedures such as, the use of high-powered tools requiring air pressure and water spray. The purpose of writing is to describe the potential of aerosols in dental practice as a medium for transmission of Covid-19. Aerosols in dental care procedures have the potential to pose a risk in transmitting Covid-19. This is because aerosols are found in the Covid-19 virus which can contaminate surfaces, dental equipment, and the air around the treatment environment which can endanger dentists, staff, and patients.

Background: Dentigerous cyst is a cyst that forms around the crown of an unerupted tooth. It begins when fluid accumulates in the layers of reduced enamel epithelium or between the epithelium and the crown of the unerupted tooth. Dentigerous cysts attach to the cementoenamel junction. Some dentigerous cysts are eccentric, developing from the lateral aspect of the follicle so that they occupy an area beside the crown instead of above the crown. In the case of dentigerous cysts with supernumerary, lesions appear to develop in the lateral aspect, so proper imaging is needed to see the expansion of the lesion. A modality that can be used to see the location and expansion of dentigerous cysts is by using a CBCT radiograph. Objective: Identification and interpretation of dentigerous cysts with supernumerary using CBCT radiography. Case Report: 12-year-old male came to the RSGM FKG Unpad bring a referral letter for CBCT photos. From the history it is known that the patient has a complaint of teeth that have not grown with swelling in the right maxilla. Case Management: Using CBCT, there were supernumerary and dentigerous cysts at 14,13. Sagittal, coronal and axial CBCT features show the position and condition of supernumerary, and give information about the location and expansion of dentigerous cyst at 14,13. Conclusion: CBCT provides a description of dentigerous cysts about location, lesion expansion, and involvement with surrounding tissue. CBCT provides an overview of lesions in sagittal, coronal and axial

Microleakage defined as the clinically undetectable passage of bacteria, fluids, molecules or ions between a cavity wall and the restorative material. Microleakage tends to occur in Class V cavities. It is caused by  marginal adaptation  which is more difficult in class  V cavities. Microfiller composite resin is developed and indicated for areas that not require a large pressure. As the development of dental materials, it has been developed a composite resin base material that is known as resin-modified glass ionomer cement. This material has purposed to reduce the limitation of conventional glass ionomer cement and take the advantage of the composite resin material. The aim of this study was   to evaluate microleakage difference of microfiler composite resin restoration with resin-modified glass ionomer cement restorations in class V anterior teeth cavities.  The methode of this  study used experimental laboratory through in vitro process . Thirty two class V cavities were prepared on labial surfaces of extracted human anterior teeth. Samples were divided into two groups. Group I included sixteen samples that have had   restorated with microfiller composite. Group II included sixteen samples that have had restorated with resin-modified glass ionomer cement. The samples were immersed into aquabides solution for 24 hours. After that, the samples were immersed into 1% methylene blue solution for 24 hours. All samples sectioned longitudinally and analyzed for microleakage as dye penetration using a stereomicroscope. Student t-test were used for statistical analysis. The resulting data showed no significantly difference between two groups. Key Word : Microleakage, microfiller composite resin, resin-modified glass ionomer cement (RMGIC), class V cavities.

Seiring dengan meningkatnya popularitas esthethic dentistry, semakin banyak pasien yang membutuhkan perawatan yang dapat meningkatkan penampilan gigi anterior. Salah satu perawatan estetik yaitu porcelain laminate veneer yang merupakan lapisan tipis, sedikit tembus cahaya, terbuat dari bahan porselen, dan berfungsi untuk melaminasi atau menutupi gigi yang mengalami kerusakan, kelainan bentuk atau perubahan warna. Pada kasus diastema gigi 12 dan peg shape gigi 22, secara anatomis gigi terlihat lebih kecil dan akan terbentuk ruang atau diastema antar gigi. Pada kasus ini dilakukan perawatan estetik porcelain laminate veneer untuk memperbaiki bentuk dan menutupi diastema ini sehingga akan dicapai estetik yang lebih baik. Penatalaksanaan kasus yaitu wax up untuk melihat kesesuaian bentuk dan proporsi veneer yang telah didesain dengan digital smile design. Pasien menyetujui untuk dilakukan crown lengthening untuk mendapatkan level gingival margin yang lebih proporsional. Dibantu dengan diagnosis wax up dan smile designing yang direncanakan pada awal perawatan, pasien mendapatkan gambaran visual dari hasil perawatan yang diharapkan. Pasien merasa puas dengan hasil perawatan. Kesimpulan yang dapat diambil yaitu porcelain laminate veneer merupakan suatu alternatif yang dapat dilakukan untuk meningkatkan penampilan estetik pada gigi anterior agar pasien mendapatkan senyum yang lebih indah.
