Abstract

Background: Bootstrap is a computer simulation-based method that provides estimation accuracy in estimating inferential statistical parameters. Purpose: This article describes a research using secondary data (n = 30) aimed to elucidate bootstrap method as the estimator of linear regression test based on the computer programs MINITAB 13, SPSS 13, and MacroMINITAB. Methods: Bootstrap regression methods determine ˆ β and Yˆ value from OLS (ordinary least square), ε i = Yi −Yˆi value, determine how many repetition for bootstrap (B), take n sample by replacement from ε i to ε (i) , Yi = Yˆi + ε (i) value, ˆ β value from sample bootstrap at i vector. If the amount of repetition less than, B a recalculation should be back to take n sample by using replacement from ε i . Otherwise, determine ˆ β from “bootstrap” methods as the average ˆ β value from the result of B times sample taken. Result: The result has similar result compared to linear regression equation with OLS method (α = 5%). The resulting regression equation for caries was = 1.90 + 2.02 (OHI-S), indicating that every one increase of OHI-S unit will result in caries increase of 2.02 units. Conclusion: This was conducted with B as many as 10,500 with 10 times iterations.

Abstract

Background: The relationship between systemic disorders and periodontal disease has been studied extensively. With few exceptions, it is more accurate to consider systemic diseases to be contributing factors in the pathogenesis of periodontal disease rather than the primary etiologic factors. The development of periodontal disease cannot be separated from the weakening of immunologic and immunopathological responses. Periodontal disease may enhance susceptibility to certain systemic diseases in several ways. Lipopolysaccharide (LPS) and Gram-positive bacteria in the biofilm and proinflammatory cytokines produced from inflamed periodontal tissues may enter the circulation system causing the development of certain systemic diseases. On the other hand, through immunologic mediators, certain systemic disease may enhance susceptibility to periodontal disease caused by the decrease of immune responses and the increase of proinflammatory cytokines. Purpose: The Purpose of this article is to review the immunologic aspect of two way relationship between systemic diseases and periodontal diseases. Review: This review studied the relationship between general health status, systemic diseases, and periodontal diseases through immunopathological responses and the weakening of the immune system in the periodontal tissue. Conclusion: there is a two-way relationship between periodontal diseases and systemic diseases.

Abstract

Background: Smoking is the biggest factor for oral cavity malignancy. Some carcinogens found in cigar will stimulate epithel cell in oral cavity and cause mechanism disturbance on tissue resistance and produce abnormal genes (oncogenes). Oncogenes ras and myc are found on malignant tumor in oral cavity which are associated with smoking. Purpose: This research is to find the expression of oncogenes rasP21 and c-myc in oral mucosa epithelial of smoker with immunocytochemistry reaction. Methods: An oral mucosal swab was performed to 30 smokers categorized as light, moderate, and chain, and 10 non smokers which was followed by immunocytochemistry reaction using antibody towards oncogene rasP21 and c-myc is reacted to identify the influence of smoking towards malignant tumor in oral cavity. The result is statistically analyzed using Kruskal-Wallis test. Result: Based on the observation result of oncogene rasP21reaction, it shows that there is significant difference between non smoker group and light smoker, compared to moderate and chain smoker group (p < 0.01). On the other side, the observation result of oncogene c-myc indicates that there is no significant difference between the group of non smokers and the group of light, moderate, and chain smokers (p > 0.05). Conclusion: The higher the possibility of oral cavity malignancy and that the antibody for rasP21 oncogene can be used as a marker for early detection of oral cavity malignancy caused by smoking.

Abstract

Background: Beside bracket position, the timing of bracket placement is one of the most essential in orthodontic treatment with fixed appliances. Even it seems simple the timing of bracket placement can be crucial and significantly influence the result of orthodontic treatment. However it is often found brackets are placed without complete understanding of its purpose and effects, which could be useless and even detrimental for the case. Purpose: The aim of this case report is to show that the timing of bracket placement could be different depending on the cases. Case: Five different cases are presented here with different timing of bracket placement. Case management: On these cases, brackets were placed on the upper arch first, on the lower arch first, or even only on some teeth first. Good and efficient orthodontic treatment results were achieved. Conclusion: For every orthodontic case, from the very beginning of treatment, bracket should be placed with the end result in mind. If brackets are correctly placed at a correct time, better treatment result could be achieved without unnecessary round tripping tooth movement.

Abstract

Background: Lipid peroxidation (LPO) has implication in pathogenesis of several pathological disorders including periodontitis. Malondialdehyde (MDA) is end products of upid peroxidation. Hyperbaric Oxygen Therapy (HBOT) involves the administration of 100% oxygen under atmosphere pressure and has been used as an adjuvant therapy, while saliva is a diagnostic tool for many oral and systemic diseases. Purpose: The aim of this study was to examine the effect of HBOT on malondialdehyde in saliva to measure lipid peroxidation in periodontitis patients with type 2 Diabetes Mellitus (DM). Methods: Eight regulated type 2 DM subjects were compared to ten unregulated periodontitis patients type 2 DM (n = 18). Pre HBOT and after 10 days HBOT with 2.4 ATA dose, unstimulated whole saliva samples from study subjects were collected, centrifuged at 3000 g for 15 minutes and were then stored at −80° C until analyzed. The MDA level was determined with 2-thiobarbituric acid by a colorimetric method at 532 nm. Results: Data showed that regulated type 2 DM had lower level of MDA (3.08 ± 0.62 ug/mol) compared with unregulated periodontally- type 2 DM subjects (5.88 ± 1.04 ug/mol) (p>0.05). MDA levels were significantly lower after HBOT in regulated DM (2.30 ± 0.46 ug/mol) compared with unregulated periodontally type 2 DM (4.09 ± 0.77ug/mol) (p < 0.05). The regulated DM subjects and post HBOT showed MDA levels lower than the periodontally-unregulated group significantly. Conclusion: The saliva of periodontitis patients with unregulated type 2 DM showed more lipid peroxidation than regulated DM type 2. HBOT decreased MDA levels in regulated and unregulated type 2 DM with periodontitis.

Abstract

Background: Elimination of subgingival plaque for prevention and treatment of periodontal diseases through scaling is a routine procedure. It is also well-known that periodontal disease is related to systemic diseases. Nevertheless, the idea how scaling procedures also able to reduce allergic symptoms i.e. eczema and asthma, is not easily accepted, because it is contradictory to the “hygiene hypothesis”. However, since allergic symptoms also depend on variable factors such as genetic, environmental and infection factors; every possible effort to eliminate or avoid from these factors had to be considered. Subgingival plaque is a source of infection, especially the Gram-negative bacteria that produced endotoxin (lipopolysaccharides, LPS), a potential stimulator of immunocompetent cells, which may also related to allergy, such as mast cells and basophils. In addition, it also triggers the “neurogenic switching” mechanism which may be initiated from chronic gingivitis. Objective: This case report may explain the possible connection between subgingival plaque and allergy based on evidence-based cases. Case: Two adult siblings who suffered from chronic gingivitis also showed different manifestations of allergy that were allergic dermatitis and asthma for years. They were also undergone unsuccessful medical treatment for years. Oral and topical corticosteroids were taken for dermatitis and inhalation for asthma. Case Management: Patients were conducted deep scaling procedures, allergic symptoms gradually diminished in days even though without usual medications. Conclusion: Concerning to the effectiveness of scaling procedures which concomitantly eliminate subgingival plaque in allergic patients, it concluded that this concept is logical. Nevertheless, further verification and collaborated study with allergic expert should be done.

Abstract

Background: TGF-β1 is a connective tissue stimulant, potential regulator for tissue repair, and promoter in wound healing. The healing of pulp perforation is decided by quantity and quality of new collagen deposition. TGF-β1 upregulates collagen transcription. However, after several weeks production of type I collagen synthesis is stopped and enzymatic degradation of collagen matrix will occur. Purpose: Observe synthesis type I collagen during the process of pulp perforation healing in 7, 14, and 21 days after being treated using TGF-β1. Methods: This research in vivo from orthodontic patients indicated for premolar extraction, between ages 10–15 years. A class V cavity preparation was created in the buccal aspect 1 mm above gingival margin until pulp exposure. Cavity was irrigated slowly with saline solution and dried with a sterile small cotton pellet. The sterile absorbable collagen membrane used, soaked with 5 μl of TGF-β1. It was covered by teflon pledge to separate from glass ionomer cement as restoration. Evaluated on day 7th, 14th, and 21st. All samples were extracted and prepared for immunohystochemical examination. Result: Data were analyzed by t-test. There was significant difference in synthesis type I collagen compared between 7–14 days and 7–21 days after treatment by TGF-β1 also Ca(OH)2. There was significant difference compared between TGF-β1 and Ca(OH)2 in 14–21 days after treatment (means TGF-β1 > Ca(OH)2). Conclusion: Elevation of synthesis type 1 collagen by TGF-β1 in 20 mg/ml.

Abstract

Background: The color change on post-endodontic treated teeth can be overcome by intracoronal tooth bleaching using walking bleach. Some agents used in walking bleach are combination of sodium peroxide and hydrogen peroxide, and combination of sodium perborate and water. Purpose: The objective of this review is to provide information and consideration of using safe and effective bleaching agents in the field of dentistry. Reviews: On one side, the use of sodium perborate and water combination does not cause the reduction of dentin hardness, enamel decay, and root resorbtion. On the other side, the use of sodium perborate and 30% hydrogen peroxide combination indicates that it takes longer time in yielding the proper color of teeth. Conclusion: The use of sodium perborate and water combination as bleaching agents is effective and safe.
