    Bahan cetak alginat merupakan bahan cetak yang :

    • A.

      Dapat digunakan berulang kali

    • B.

      Hydrocolloid irreversible

    • C.

      Cara mencetaknya dengan memasukkan langsung bubuk alginat ke dalam mulut

    • E.

      Hydrocolloid reversible

    Correct Answer
    B. Hydrocolloid irreversible
    Explanation
    The correct answer is "Hydrocolloid irreversible." This means that the alginat printing material cannot be reused and is not reversible. It implies that once the material is set, it cannot be changed back to its original state. This characteristic is important in dental impressions as it allows for accurate and stable molds to be created for dental procedures.

Pasien ingin lubang giginya ditambal. Dari hasil pemeriksaan intra oral tampak karies media yang luas meliputi bagian mesial, bukal dan oklusal. Ditemukan hasil positif pada tes dingin tetapi negatif pada perkusi dan tekan. Pasien disarankan untuk dibuatkan restorasi indirek berupa mahkota logam paduan Nikel Kromium.Ditinjau dari bahan mahkota yang digunakan pada kasus tersebut, salah satu kelebihan Nikel Kromium adalah :

    • D.

      Oklusal foto

    • E.

      Lateral Foto

    Correct Answer
    D. Oklusal foto
    Explanation
    The most suitable radiographic examination for the given case is an Oklusal foto. This is because the patient presents with complaints of upper jaw teeth mobility after an accident, and there is a visible scar on the upper lip. Intraoral examination reveals mobility in teeth 11, 12, and 21, indicating movement from their sockets. To further assess the condition, an Oklusal foto would provide a comprehensive view of the upper teeth and their alignment, helping to determine the extent of damage and the appropriate treatment plan.

    Correct Answer
    B. Sulit memposisikan film yang sejajar dengan objek
    Explanation
    The correct answer is "Sulit memposisikan film yang sejajar dengan objek." This is because parallel technique in radiography requires positioning the film parallel to the object being imaged. However, this can be challenging as it may be difficult to align the film properly with the object, resulting in improper positioning and potentially affecting the accuracy of the radiographic image.

    • D.

      Film diletakkan vertical dengan sudut vertical 15o

    • E.

      Film diletakkan vertical dengan sudut vertical 5-8o

    Correct Answer
    A. Film dilatakkan horinzontal dengan sudut vertical 30o
    Explanation
    The correct answer is "Film dilatakkan horinzontal dengan sudut vertical 30o." This means that the film should be placed horizontally with a vertical angle of 30 degrees. This positioning is important in bitewing technique as it allows for proper visualization of the interdental spaces and the alveolar bone level. Placing the film horizontally helps in capturing clear and accurate images of the teeth and surrounding structures. The vertical angle of 30 degrees ensures that the film is positioned correctly to capture the desired area of interest.

    Explanation
    The correct answer is Trichion - Menton. The term "morfognomik" refers to the study of facial morphology. Trichion is the highest point of the forehead, while Menton is the most inferior point on the chin. Therefore, measuring the distance between Trichion and Menton provides an indication of the vertical height of the face.

    Explanation
    Endochondral ossification is the process of bone formation that involves the replacement of a cartilage model with bone tissue. It occurs in long bones, such as the femur and humerus, as well as in the vertebrae and the base of the skull. However, it does not occur in the alveolar bone, which is the bone that supports the teeth in the jaw. Therefore, the correct answer is "Terjadi pada tulang alveolar."

    Correct Answer
    D. Kelas III Angle tipe I
    Explanation
    The correct answer is Kelas III Angle tipe I. This is because Angle's classification categorizes malocclusion based on the relationship between the first molars. In Class III malocclusion, the lower first molar is positioned anteriorly to the upper first molar, and in Type I, the incisal edges of the lower incisors are in an edge-to-edge relationship with the upper incisors.

    Correct Answer
    C. Pemeriksaan vitalitas
    Explanation
    The correct answer is "Pemeriksaan vitalitas". In the context of a patient with a cavity, the first examination that should be done is to assess the vitality of the tooth. This involves testing the responsiveness of the tooth's pulp to stimuli such as temperature or electric pulp testing. By determining the vitality of the tooth, the dentist can assess the severity of the cavity and plan the appropriate treatment.

    • E.

      Actinobachilus actinomiceten comitens

    Correct Answer
    B. Streptococcus mutans
    Explanation
    Streptococcus mutans is a type of bacteria that plays a significant role in the development of dental caries (tooth decay). It is commonly found in the oral cavity and has the ability to produce acid from dietary carbohydrates, which leads to the demineralization of tooth enamel. This acid production by Streptococcus mutans contributes to the formation of dental plaque and the breakdown of the tooth structure, ultimately leading to the formation of cavities. Therefore, it is considered one of the main bacteria involved in the process of dental caries.

    • C.

      Glass ionomer

    • D.

      Logam cor

    • E.

      Resin modified glass ionomer

    Correct Answer
    A. Resin komposit
    Explanation
    Resin komposit is the most suitable material for restoring the occlusal surface of a first molar tooth. It is a tooth-colored material that can be bonded to the tooth structure, providing a strong and aesthetic restoration. Amalgam is a metal-based material that is not commonly used for restoring the occlusal surface of teeth. Glass ionomer is a tooth-colored material, but it is not as strong as resin composites. Logam cor refers to cast metal restorations, which are not commonly used for occlusal restorations. Resin modified glass ionomer is a combination of glass ionomer and resin composite, but it is not the most suitable material for occlusal restorations.

    Seorang anak perempuan usia 8 tahun diantar ibunya,  datang ke RSGMP dengan keluhan  gigi belakang kanan sakit kalau untuk makan. Gigi sudah lama lubang, pernah sakit 3 bulan yang lalu. Hasil pemeriksaan klinis diperoleh gigi 46 terdapat karies pada permukaan oklusal, tes vitalitas (-). Data radiograf menunjukkan gigi 46 tampak perforasi hingga pulpa,  apeks gigi masih terbuka serta periapikal tampak dalam batas normal. Apakah perawatan yang tepat untuk gigi 46?

    • A.

      Apeksogenesis

    • B.

      Apeks reseksi

    • C.

      Apeksifikasi

    • D.

      Pulpektomi

    • E.

      Pulpotomi

    Correct Answer
    C. Apeksifikasi
    Explanation
    The correct treatment for tooth 46 is apeksifikasi. Apeksifikasi is a procedure performed to encourage the formation of a calcified barrier at the apex of the tooth. In this case, the tooth has a perforation that extends to the pulp, but the periapical area appears normal. Apeksifikasi can help to promote the closure of the apex and prevent further infection or damage to the tooth. Other treatment options such as pulpektomi or pulpotomi may not be suitable in this case as the tooth is still vital.

    The correct answer is "Labial shoulder, palatal chamfer." In the preparation of a porcelain fused to metal crown, a labial shoulder is created on the labial surface of the tooth to provide a stable and retentive finish line. On the palatal surface, a chamfer is created to allow for proper seating of the crown and to provide space for the metal framework and porcelain. Therefore, the combination of a labial shoulder and palatal chamfer is the most suitable for the preparation of a porcelain fused to metal crown.
