Abstract

Background: In theory, allergic diseases including asthma, was the resultof exposure to a transmissible agent and do not depend on early infection which is said to make children more allergy-resistant. This seems, to be a direct contradiction to the hygiene hypothesis, since epidemiologic evidence can be cited in this theorys support. The fact that nearly all childrenwith asthma are allergic, but only a small proportion of allergicchildren have asthma, at least raises the possibility that someadditional factor is involved. That this additional factor might be a transmissible agent is also suggested by the similarity between the gross epidemiologic patterns of children with paralyticpoliomyelitis in the 1950s and children with asthma currently. Purpose: The purpose of this study was to reveal the possible relationship between the transmissions of allergic asthma and periodontopathic bacteria. Reviews: Recent researches showed that periodontopathic bacteria are transmissible from mother and caregivers to infants. In addition, a collaborated research that was conducted by dental practitioners and pediatricians revealed that Gram-negative bacteria were significantly predominant (p = 0.001) in uncontrolled allergic asthmatic children compared to well-controlled ones. Nevertheless, how does these two phenomenon related was still uncertain. Literatures showed that periodontopathic bacteria modulates host immune response and sometimes caused disadvantageous effect to allergic asthma. Conclusion: According to the ability of periodontopathic bacteria and its components to stimulate immunocompetent cells, it is possible that they are able to modify host-immune response which tends to increase allergic asthma symptoms.

Abstract

Background: Calprotectin, a major cytosolic protein of leukocytes, is detected in neutrophils and monocytes/machrophages. This protein is known to be a marker for several inflammatory diseases including periodontitis. In type 2 diabetes mellitus patients, the severity of periodontitis was strongly thought to be caused by decreasing of leukocytes function such as neutrophils. Previous research found that the calprotectin level in serum of periodontitis patients with type 2 DM is higher than periodontits patients non DM. Purpose: The aim of this study was to determine calprotectin mRNA (MRP8/MRP14) expression in human neutrophils of periodontitis patients with type 2 diabetes mellitus. Methods: Neutrophils were isolated from the peripheral blood of periodontitis patients with uncontrolled type 2 DM, controlled type 2 DM, and non DM. The expression of calprotectin mRNA (MRP8 and MRP14) were detected by RTPCR. Result: The result showed that the value of mRNA calprotectin expression in DM patients were higher than non DM, and the highest expression was on the uncontrolled type 2 DM. Conclusion: The basal level of calprotectin mRNA MRP8/MRP14 expression increased in neutrophil of periodontitis patient with type 2 DM compared non diabetic subjects. It was suggested that high basal level of calprotectin mRNA has a role in the regulation of periodontitis severity with diabetes mellitus patients.

Abstract

Background: Recurrent aphthous stomatitis (RAS) are painful oral ulcerations that recur from days to months or even years. It represents the most common lesion of the oral mucosa with prevalence ranging from 15% to 30%. Although the clinical characteristics of RAS are well defined, the precise etiopathogenesis of RAS remains unclear. Since the etiology of RAS remains unknown, there is no definitive treatment. RAS responds quite well to the use of topical or systemic antiinflammatory drugs, particularly corticosteroids. Purpose: The objective of this paper is to discuss the treatment of RAS with secondary infection. Case: This paper reported a case of 22-year-old man with multiple oral ulcers that did not heal for 7 months. Case Management: These ulcers were diagnosed as RAS major with secondary infection that caused by normal oral flora (aerobic and anaerobic bacteria) and treated with metronidazole (topical and oral) and ciprofloxacin (oral). These lesions healed in 3 weeks with scars. Conclusion: Large ulcer without signs of malignancy that contaminated with normal oral flora will delayed in healing, but with rational treatment RAS mayor with secondary infection has good prognosis.

Abstract

Background: Plaque is the main cause of teeth and periodontal tissue damage, which usually accumulates on crown surfaces. To avoid this, plaque control is the best way that not only has a close connection to oral hygiene but also become important element in dental practice. Previously, xylitol was used as alternative sweetener for diabetic patients, but later it is used to maintain healthy teeth. Xylitol is capable to inhibit Streptococcus mutans growth which changes sugar and other carbohydrate into acid, because xylitol cannot be fermented. Purpose: This study was aimed to understand the inhibition capability of toothpaste containing xylitol to plaque formation on fixed bridge. Methods: This clinical experiment study was carried out in fifteen patients wearing fixed bridge at Prosthodontics Department, Faculty of Dentistry, Airlangga University in Surabaya from 2005 to 2008. Samples were based on selective random sampling technique. Plaque index was analyzed by Mann Whitney test. Result: This study showed that there was significant difference of plaque scores in patients who brush their teeth using xylitol containing toothpaste compared to the control group (placebo). Conclusion: Xylitol was capable to inhibit plaque formation on fixed bridge.

Abstract

Background: The carving wax is used as a medium in dental anatomy study. This wax composes of many waxes and sometimes a filler is added. Carving wax is not sold in Indonesian market. Whereas the gradients of carving wax such as beeswax, paraffin and bentonite are abundant in Indonesia. Based on that fact, to make high quality and standard,the exact composition if this carving wax should be known. Purpose: The aim of this study was to investigate the effect of carving wax composition with Ca-bentonite filler on the melting point, hardness, and thermal expansion. Methods: Five carving wax compositions were made with paraffin, Ca-bentonite, carnauba wax, and beeswax in ratio (% weight): 50:20:25:5 (KI), 55:15:25:5 (KII), 60:10:25:5 (KIII), 65:5:25:5 (KIV), 70:0:25:5(KV). All components were melted, then poured into the melting point, hardness, and thermal expansion moulds (n = 5). Three carving wax properties were tested: melting point by melting point apparatus; hardness by penetrometer; thermal expansion by digital sliding caliper. The data were analyzed statistically using One-Way ANOVA and LSD0.05. Result: The Ca-bentonite addition influenced the melting point and thermal expansion of carving wax with significant differences between KI and other groups (p < 0.05). Ca-bentonite addition influenced the carving wax hardness and the mean differences among the groups were significant (p < 0.05). Conclusion: Ca-bentonite filler addition on the composition of carving wax influenced the physical and mechanical properties. The carving wax with high Ca-bentonite concentration had high melting point and hardness, but low thermal expansion.

Abstract

Background: Indonesia is a tropical country with temperature variation. A lot of dental clinics do not use air conditioner. The room temperature influences water temperature for mixing alginate impression materials. Purpose: The aim of this study was to investigate the functional relationship of room temperature and initial setting time of alginate impression materials. Methods: The New Kromopan® alginate (normal and fast sets) were used. The initial setting time were tested at 23 (control), 24, 25, 26, 27, 28, 29, 30 and 31 degrees Celcius room temperatures (n = 5). The initial setting time was tested based on ANSI/ADA Specification no. 18 (ISO 1563). The alginate powder was mixed with distilled water (23/50 ratio), put in the metal ring mould, and the initial setting time was measured by test rod. Data were statistically analyzed by linear regression (α = 0.05). result: The initial setting times were 149.60 ± 0.55 (control) and 96.40 ± 0.89 (31° C) seconds for normal set, and 122.00 ± 1.00 (control) and 69.60 ± 0.55 (31° C) seconds for fast set. The coefficient of determination of room temperature to initial setting time of alginate were R2 = 0.74 (normal set) and R2 = 0.88 (fast set). The regression equation for normal set was Y = 257.6 – 5.5 X (p < 0.01) and fast set was Y = 237.7 – 5.6 X (p < 0.01). Conclusions: The room temperature gave high contribution and became a strength predictor for initial setting time of alginates. The share contribution to the setting time was 0.74% for normal set and 0.88% for fast set alginates.

Abstract

Background: Aggressive periodontitis might occur as a result of complex interplay between bacteria and host defence, therefore, the host susceptibility plays important role. Antimicrobial agents that could enhance host defence are required. Clindamycin might influence host defence. Purpose: The purpose of this study was to determine the influence of clindamycin on level of Immunoglobulin-G (IgG) patients with aggressive periodontitis, and its mechanism. Methods: This study used the pre-test post-test control group design. Eighteen aggressive periodontitis patients were divided into 2 groups at random. Group 1 (treatment): 9 aggressive periodontitis patients were given with clindamycin of 150mg orally, 4 times a day, for 7 days. Group 2 (control): 9 aggressive periodontitis patients were given with tetracycline of 250mg orally, 4 times a day for 12 days, and then metronidazole of 200mg orally, 3 times a day for 10 days. Blood sample was collected from vena cubiti mediana. Level of IgG was measured at base line and day 28. Data were analyzed statistically by using t-test (a = 0.05). Result: Examination for IgG level showed there was significant difference between pre-test and post-test (p < 0.05). Level of IgG was significantly increased after therapy, both in treatment and control group. The increase of IgG level in treatment group was not different significantly from control group (p>0.05). Conclusions: This study shows that clindamycin can be used as drug of choice for the treatment of aggressive periodontitis since clindamycin can improve the immunity status of aggressive periodontitis patients.

Abstract

Background: Tooth agenesis is one of the most common developmental anomalies in human, which one or a few teeth are absent because they have never formed, may cause cosmetic or occlusal harm, while severe agenesis which are relatively rare require clinical attention to support and maintain the dental function. Molecular studies have demonstrated that tooth development is under strict genetic control. Purpose: This article want to review the genetic regulating that are responsible for tooth agenesis especially the role of Msx1 and Pax9 in pathogenetic mechanisms of tooth agenesis. Review: Tooth agenesis is a consequence of a qualitatively or quantitatively impaired function of genetic networks, which regulate tooth development. Mutations in Msx1 and Pax9 genes are dominant for tooth agenesis in humans. The Pax9 gene, which codes for a paired domain-containing transcription factor that plays an essential role in the development of mammal dentition, has been associated with selective tooth agenesis in humans and mice. Conclusion: Reduced amount of functional Msx1 or Pax9 protein in the tooth forming cells is able to cause severe and selective tooth agenesis. There are differences in the frequency of agenesis of specific teeth associated with the defects in Msx1 and defects in Pax9.

Abstract

Background: Composite resin is a tooth-colored filling material containing Bis-GMA which exhibits water sorption properties. People tend to consume soft drink with various colors. Water sorption properties can alter the color stability of composite resin purpose. Purpose: This study was to determine the influence of immersion durations of composite resin in soft drink on color stability. Methods: The visible-light cured hybrid composite resin and soft drink were used. Ten disk specimens (2.5 mm thickness and 15 mm diameter) of composite resin were prepared and light cured for 20 seconds, then stored in distilled water for 24 hours at 37° C. The initial color of specimens were measured by Chromameter. After that, each specimen was immersed in 30 ml of soft drink up to 48, 72, and 96 hours at 37° C. The specimens’ color were measured again after each immersion. The color changes were calculated by CIE L*a*b* system formula. The data was analyzed by One-Way ANOVA and LSD (α = 0.05). Result: The ANOVA showed that the immersion durations of composite resin in soft drinks had significant influence on the color stability (p < 0.05). The LSD0.05 tests showed significant differences among all groups. The least color change was detected from the group of 48 hours immersion, while the greatest color change was from the group of 96 hours immersion. Conclusions: The immersion of composite resin in soft drinks influenced the color stability (began after 48 hours immersion).

Abstract

Background: The prevention and management of pit and fissure caries has become relatively more important in recent times. There is a need for an effective preventive measure against pit and fissure caries. Purpose: The purpose of this study was to investigate the effect of laser beam as a cleaning method of pits and fissures. Methods: Ho-YAG laser which has a wavelength of 2.1 µm was used in this experiment. The specimens were extracted human teeth. The effect of three cleaning methods was examined comparatively by scoring the cleaned area of fissure, namely laser irradiation with Ho-YAG laser, chemico-mechanical with combination of 10% NaOCl and ultrasonic scaler and mechanical with ultrasonic scaler. Vertico-bucco-lingual serial ground sections of each tooth were observed under light microscopy. Scoring the depth of cleaned area was performed by comparing the depth of fissure. result: Progressive result was obtained on the cleaning effect of three methods laser irradiation methods which was the most effective compared to other methods but statistically was not significant. Cleaned area of laser irradiation method was 48.91%, chemico-mechanical method was 41.77% and mechanical method was 36.78%. Conclusion: Holmium -yttrium aluminum garner laser is a relatively new method for pit and fissure cleaning even though the effectivity is not yet maximal. More research is needed to maximize the use of this laser.
