Abstract

Getah perca or known as gutta percha is the most widely used for the root canal filling material. Indonesia has a big potency to product dental gutta percha, as it is the biggest country that has productions of natural gutta percha. Indonesia is conducting natural gutta percha at PT. Perkebunann Nusantara VIII Cipetir-Jawa Barat. Chemical composition and bond are very important to be found out before making the root canal filling material from natural gutta percha. This study purposed to know the chemical composition differences between natural gutta percha and dental gutta percha using Fourier Transform Infrared Spectrometry (FTIR) characterizations. The methode is descriptive study that studies the FTIR Characterization between natural gutta percha and dental gutta percha. The characterized samples, each consist 20 mg of natural gutta percha and 20 mg dental gutta percha.The IR results the difference of transmission between natural gutta percha and dental gutta percha. Both show the presence of hydroxyl groups in the material indicates that the process is oxidative, but the dental gutta percha contain pro oxidant that increase the oxidation. The conclusion of this study showed there is FTIR characterization difference between natural gutta percha and dental gutta percha.

Abstract

Gutta percha is used for many functions in dentistry but the most popular is the root canal filler. This root canal filler is not a pure gutta percha but mixed with other materials, such as zinc oxide, wax, resi, and metal salts. The raw material of gutta percha dentistry is obtained from gutta percha tree (Palaquium gutta Baill) which in Indonesia has been cultivated in commercial scale since 1901 in Cipetir Sukabumi, in this location since 1921 is also equipped with its processing plant. This condition is very supportive if that gutta percha will be used as raw material of gutta percha dentistry. However, this material is a raw material that needs to be mixed with other materials in order to conform the standardization in dentistry, for that needed a series of research to be able to make gutta percha dentistry in Indonesia.

Abstract

Oral lesions are relatively common findings in clinical practice, can occur due to various factors such as trauma, systemic diseases, autoimmune disorders, malignancies. Local trauma as one of the cause of oral lesions majority due to poor dentures, fractured restorations and sharp edges of teeth. The lesions are commonly found on the mucosa that is subjected to the source of trauma such as buccal mucosa, lateral border of the tongue or lips. Removable partial denture is a denture that can be removed and reinserted without professional help. Poor removable denture which is an ill-fitting denture, rough/sharp/overextended flanges, or lack of retention/stability could cause oral lesions. This case report describes a 76 old year man complained of pain on his right lateral tongue since 6 months ago. He was wearing a removable upper right denture which cannot be remove for about a year. It was a rough and sharp self-curing acrylic denture. There was erythematous and pain on his lateral right of the tongue but no induration on palpation. Triamcinolone acetonide 0,1% in orabase was the given treatment for the right lateral of the tongue and referred him to the prosthodontic department for replacing the denture. The oral lesion was healed after one week of treatment and the poor denture was removed. As a conclusion dentures should be made properly by the expert in order to prevent oral lesions.
