Abstract

The application of methacrylate resin and the derivation (composite resin and dentin bonding) in clinical conservative dentistry has been widely developed. This material could be used to restore class I-V cavity with good aesthetic due to the compatible color with tooth. Composite resin adhesion hydrophobically in enamel that is due to mechanic retention in the form of resin tags which penetrates into enamel porosity. Meanwhile hydrophilic dentin bonding adhesion due to the chemical reaction between functional groups of amino collagen with carbonyl in dentin bonding forming amide binding. In addition mechanical retention in which dentin bonding penetrating into nano inter fibrilar cavity then polymerized. The success of methacrylate resin adhesion restoration is decided by enamel porosity, wetting character of resin, wetting contact angle, good etching acid, optimal humidity of tooth surface, the accuracy of dentist during filling is done etc.

Abstract

High-strength all-ceramic systems for fixed partial dentures (FPDs) is gaining popularity as an alternative to the well established metal-ceramic FPDs. Several new framework materials and technique such as lithium disilicate, aluminum oxide and yttrium tetragonal zirconia polycrystal have been developed with improved strength, marginal discrepancy and esthetics. Since not every all-ceramic system can be used for a variety application, proper selection of the materials is an important for the success of all-ceramic FPDs. The longevity of dental restorations is an important health concern and the clinician placed great emphasis on mechanical properties to define the clinical indication of the ceramic materials because of their brittleness and low fracture toughness. The stronger and tougher framework material would improve the reliability and the longevity of dental restoration. To fabricated of an all-ceramic FPDs, material would be required with a flexural strength in excess of 300 MPa and fracture toughness 3 MPa/m½. Zirconium has a better mechanical properties than alumina and lithium disilicate glass-ceramic, result from the transformation toughening, free of glass phase and minimal flaws. Whereas lithium disilicate glass-ceramic has a better translucency than alumina and zirconium based ceramic, result from the higher content of glass phase than that two materials. The purpose of this article is to present the information that can guide the practioner in the decision making process about all-ceramic FPDs systems. It can be concluded that the all-ceramic FPDs are seems to be an acceptable clinically prosthodontic treatment according to the short-term studies and the lithium disilicate and alumina-based ceramic materials are acceptable for 3 units anterior FPDs, whereas zirconia-based ceramic are acceptable for 3–5 units anterior and posterior FPDs with 2 pontics. However, further investigation and more clinical long-term follow-up studies are needed.

Abstract

Gender is a social relationship concept that differentiates role and function between man and women. Equality of rights and obligations between man and woman have been normatively guaranteed and the Constitution does not explicitly discriminate the rights and obligations of woman in law and government, in occupation and decent life, in politics, in religion and beliefs, and in national defend. Related with gender perspective, the need of health worker especially dentist worker has to be determined and planned properly. The productivity is one of the factor on dentist worker, that affect on the quality of health delivary. Some companies try to increase efficiency in performing their activities and try to measure activities they do. In this case, time & motion study method is one of the solutions to help the company measuring their activity. Using these techniques, company can measure the productivity of resources used for every activity. In order to get better performance in cost reduction, the company should assign their cost to the product resulted. Determination of the Standart time to work is one of the method that contain high value of efeciency to gain the productivity. The aim of this study was to learn how gender has an effect on dentist’s work performance. The time of completing dentist’s task i.e: teeth extraction were measured and the standard time were determined. In addition the patient’s respond were measured through questionair. This study was conducted in East Java. The conclusion of this study revealed that there was no difference of work performance between male and female dentist’s.

Abstract

Cold curing acrylic is more porous, having more residual monomer and dimensional change. Physical property of cold curing acrylic shows to have very small dimensional change resulted from imperfect polymerization process and if dimensional change occurs, it would cause improper use of orthodontic appliance. Orthodontic acrylic base plate which is made of cold curing acrylic, in order to achieve good result, it is suggested to use hydro flask or polyclav with water temperature 45°–50°C and polyclav and pressure in 2–3 atm during polymerization process. Even though cold curing acrylic could polymerization at room temperature, the purpose to use hydro flask or polyclav is to reduce residual monomer and porosity. The purpose of the present study is to know the difference in dimensional accuracy of orthodontic acrylic at various polymerization temperature. The samples of the study were 18 acrylic base plate sized 65 × 10 × 25 mm classified into 3 control groups with polymerization temperature at 30° C, 40° C and 50° C. Measurement was done using caliper in order to know dimensional accuracy of orthodontic acrylic. The measurement result was tabulated and One-Way ANOVA test one was done with significant level 95%, the probability result 0,0055 was found which means there was significant difference among each control group. LSD test showed that group I polymerization at 30° C, group II polymerization at 40° C, and group III polymerization at 50°C there was significant difference. The conclusion of this study is : dimensional difference of orthodontic acrylic base plate on polymerization at group I at 30° C, group II at 40° C, and group III at 50° C water temperature and could achieve better dimensional accuracy comparing with polymerization at 50° C.

Abstract

Erythema multiforme is an acute inflammatory disease of the skin and mucous membranes that causes a variety of the skin lesionhence the name ‘multiforme’.The oral mucosa looks severely inflamed, but the feature are non specific and usually a biopsy is required in order to confirm the diagnosis. Cracked, bleeding, Crusted, swollen and ulcers of the lips is very characteristic of erythema multiforme, and lip involvement may cause significant morbidity. EM is assumed as an immune complex disorder which rises as a result of an immune response to an external agent such as herpes simplex virus or various drugs. We reported: 14-year girl, complained she suffered from painful oral ulceration for one week. One weeks advance the patient received a treatment of paracetamol and paramex for febris, headache and cough. Clinical examination of the skin showed no signs of cutaneous involvement. Other site such as the conjunctival, and genital were also free of lesions. The patients had several red-based superficial erosions on the upper and lower lips accompanied by crusting and bleeding. Intra oral findings showed multiple irregular erosions, ulcers and intense erythematous areas, mainly on the labial mucosa. The clinical diagnosis of EM was concluded by anamnesis and clinical appearance, with differential diagnosis of secondary herpes infection (herpes labialis) and pemphigus vulgaris. Systemic and topical corticosteroid therapy is frequently used to treat EM Although it may partially suppress the disease. Objective: This report explains and describes the management of patients with EM which may help dentists to determine an accurate diagnosis to avoid further complication and to give medical intervention to the disease. Conclusion: Early recognition of this disease may prevent delayed diagnosis and incorrect treatment.

Abstract

Xylitol was first discovered in the 19th century, it wasn’t until the 1960’s that commercial production was first implemented. Recent studies showed that xylitol chewing gum is beneficial for preventing caries and periodontal disease. Therefore, it is also advantageous for orthodontic treatment, especially the fixed orthodontics patients who have difficulties in acquiring optimal oral health, particularly periodontal health which important in remodeling. However, how consuming xylitol chewing gum may stimulate tooth movement and preventing root resorption is still unclear. It is suggested that chewing activities may stimulate tooth movement, since jaw hypofunction leads to lower mineral apposition and bone function; and narrow periodontal ligament (PDL). These conditions may lead to impaired remodeling process, and increases the susceptibility of root resorption during orthodontic tooth movement. Moreover, since stimulation of the PDL could be mechanoreceptive (i.e. chewing action) or nociceptive (i.e. painful stimulation), periodontal nerve fibers are supposed to play an important role in bone remodeling. It is supported by a study which revealed that during tooth movement, the galanin-containing immunoreactive nerve fibers, a part of primary sensory neurons in the PDL is increasing. Galanin is able to induce osteoclast differentiation that needed for bone resorption in orthodontic treatment. The objective of this study is to elucidate a new concept in using xylitol chewing gum as an excellent media to have a faster and healthier orthodontic movement. Since continuous chewing stimulates the PDL which enhances tooth movement, improves oral health, and prevents root resorption; it is concluded that this concept is possible.
