The post is used to retain a core that supports the definitive restoration. One of the important factors in the prognosis of post-endodontic restoration system is the post space preparation design which effects to the distribution of stresses. The purpose of this study was to analyze the effect of post space preparation design at the cervical area of the root to the stress distribution on static loading using (two dimensions) finite element method. This was a numeric simulation study using two 2D digital models: seat and non-seat design of maxillary central incisors using commercial software of finite element. The procedures of pre-processing, solution, and post-processing were used to evaluate the distribution of internal stress caused by static loading 110 N which was applied at 135° angle with tooth longitudinal axis on the palatal surface of the core. Both models of restoration with cast post-core of Orden alloy were divided into 15,400 triangular elements. This study showed that the stress distribution from the loading location to the location of stress concentration and the value of maximum stress at cervical part of the root at non-seat design was lower than the seat design (seat design 3.69 times greater than non-seat). This study proved that non-seat design distributes stress better than seat design.

Background. 4-nitroquinoline 1-oxide (4NQO) is a water soluble carcinogen which is often used to induce cancer in oral cavity. Objective. The purpose of this study was to know the incidence of histopathological lesions in the tongue of rats after administration of 4-nitroquinoline 1-oxide (4NQO) for a model of oral carcinogenesis in the animal experimental laboratory. Materials and Methods. This study was conducted in the Department of Pathological Anatomy, Faculty of Medicine, University of Indonesia (FMUI). 4NQO (30 ppm) was administered by drinking water ad libitum to the Sprague Dawley (SD) rats during different time inductions (4-9 and 36-46 weeks). The present of tumor in oral cavity of the 4NQO-treated rats were observed macroscopically and microscopically. Tumor volume were measured based on the formula established by G. Carlsson. The degree of histological changes was determined according to observation towards their Hematoxylin and Eosin (HE) staining results. Results. Dysplasia and invasive squamous cell carcinoma (SCC) were respectively found in the tongue of the group given 4NQO for 4-9 and 36-46 weeks. The tongue from rats (4NQO for 36-46 weeks) exhibited whitish protuberant nodular lesions with the longest diameter was 17 mm. The histopathological lesion incidences for dysplasia and invasive SCC respectively were 25% (5/20) and 75% (15/20). The rats had tumor in their tongues with variation of degree alteration which proportional to the induction time. The extension of 4NQO induction time increasing the degree of change in the tumor. Conclusion. 4NQO represents a good model of carcinoma of tongue and gives consistence results with histological changes degree being related to duration of exposure.

Deoxyribonucleic acid (DNA) is a genetic material which is found in all living organisms. On the human cell or eukaryotes cell, the DNA is found in the nucleus cell and the mitochondria. The DNA arrangement on each cell in human body is the same, that is why, for the analysis meaning, DNA can be isolated from any cell in the body. The source of DNA to be analyzed usually coming from the blood sample by an injection method, such a way resulting in pain and bringing about constraint. Therefore, a study was carried out to look for an alternative of DNA isolation. The aim of this experimental study was to get an optimal DNA isolation method by using oral mucous smear method with a purpose to get a quick and easy DNA isolation. The investigation materials were in the form of samples which were taken from the oral epithelial mucous cells out of three different subjects. The epithelial cells were obtained by the oral mucous smear method which in a variation of two, four and six times of smear applications, respectively. The DNA was then isolated using buffer extraction method. The concentrations of DNA were measured by using ultraviolet spectrophotometer at 260 nm wavelength. The results of DNA isolation were analyzed by Polymerase Chain Reaction (PCR) technique. The optimal DNA isolation could be analyzed by PCR technique. The experimental results show that from three different subjects of study, DNA can be isolated optimally by oral mucous smear method with six times of smear applications.

Introduction: The dentist’s evaluation of complete denture often differs from the patient’s evaluation. Dentists are more prioritising the clinical aspects of the dentures, such as vertical dimension, aesthetical, stability, and denture-bearing area, while patients are more prioritising their satisfaction based on aspects such as aesthetical, mastication, comfort, and phonetic ability. The purpose of this study was to determine the relationship between the stability of maxillary and mandibular denture-bearing area towards the complete denture patient’s satisfaction level. Methods: This study was a cross-sectional study with purposive sampling as the sampling method. The sample of this study was as much as 30 complete denture patient. The patients were interviewed using a questionnaire in each of the patient’s house, to obtain a more honest patient’s satisfaction assessment on the dentures, without being affected by any clinical environment and assessment. The interview was conducted before the clinical evaluation was performed. The statistical analysis was performed using the Fisher’s test. The stability of the denture-bearing area was evaluated clinically. Mastication ability and patient’s comfort were evaluated using a questionnaire. Result: A significant relationship was found between the stability of maxillary denture-bearing area towards mastication (p = 0.012), and the stability of mandibular denture-bearing area towards mastication (p = 0.029); while no significant relationship was found between the stability of maxillary denture-bearing area towards the patient’s comfort (p = 0,051), and the stability of mandibular denture-bearing area towards the patient’s comfort (p = 0,547). Conclusion: There was a relationship between the stability of maxillary and mandibular denture-bearing area towards the patient’s masticatory satisfaction level. However, the relationship between the stability of maxillary and mandibular denture-bearing area towards the patient’s comfort was not found.
