Abstract

Trauma arising from tooth extraction will experience a natural healing process but alveolar defects will only partially heal. Along with bone growth, there is also a resorption process in the alveolar ridge. Socket preservation with bone graft can be a solution to maintain ridge dimensions and contours so that bone resorption can be minimized. Hydroxyapatite is a synthetic biomaterial that repairs damage after tooth extraction and regenerates bone associated with implant placement and denture bases as a replacement procedure for missing teeth. This paper was created to discuss the role of Hydroxyapatite (HA) as bone filler after tooth extraction. Socket preservation or preservation of the socket or alveolar ridge preservation is a procedure performed to reduce the process of bone loss after tooth extraction. This loss of bone volume may result in the denture becoming loose, or an insufficient amount of bone width to place the implant. Hydroxyapatite (HA) is an alloplastic material commonly used as a replacement for bone grafts due to its inherent bioactive properties that support osteoconduction. HA is a synthetic biomaterial that can repair damage after tooth extraction and regenerate bone associated with missing tooth replacement procedures.

Abstract

One of the natural resins in the world market which is dominated by production from Indonesia is damar. Damar is a resin produced by the Shorea javanica tree. This resin is known to have the best quality compared to other types of resin. In Indonesia, this plant grows well in Sumatra, Kalimantan, Sulawesi, and Maluku, but is mainly produced in the Krui Coastal area of Lampung in an agroforest system known as Repong Damar. From the Shorea javanica tree, two types of resin are produced, namely damar mata kucing and damar batu. Damar mata kucing is obtained by tapping while rock resin is obtained by picking up resin which drips naturally onto the ground. The resin quality standard is stipulated in the Standar Nasional Indonesia (SNI) 2900.1:2012 for visual test and SNI 2900.2:2013 for for laboratory tests. Resin has properties in accordance with the requirements of dental materials, such as white to yellow colour, non-volatile, and insoluble in water. But it also has unsuitable properties such as brittle, sticky at room temperature, not heat resistant, flammable, and will change color when stored for a long time. It is concluded that resin modification has the potential to be used as raw material for dentistry, but it needs to be modified and its mechanical properties need to be tested.

Abstract

Chronic periapical abscess is an advanced suppurative lesion from the acute phase, originating from the inflammation of necrotic pulp tissue, and is accompanied by symptoms of pain that have subsided, and can return to the acute phase if the etiologic factor is not eliminated. A 24-year-old female patient came to RSGM Unjani with a complaint of a pus-filled lump that irritates the palate of anterior teeth, feeling uncomfortable when chewing on her right upper anterior tooth since 3 weeks ago. The patient had been treated but the complaints did not improve. This case report shows that the administration of penicillin and metronidazole antibiotics which are used together as a combination of antibiotics is considered effective in suppressing the bacteria that cause suppurative inflammation.
