<![CDATA[Crossbite anterior adalah keadaan dimana terdapat hubungan labiolingual yang tidak normal antara satu atau lebih gigi insisivus maksila dengan mandibula. Problem pada masa tumbuh kembang ini seringkali terjadi pada masa gigi bercampur dan perawatan dini sangat disarankan karena maloklusi ini tidak dapat terkoreksi dengan pertumbuhan dan bertambahnya usia. Beberapa tekhnik yang berbeda telah digunakan untuk koreksi crossbite anterior.Seorang anak perempuan berusia 10 tahun mengeluhkan kondisi gigi depannya dan ketidaknyamanan dalam menggigit. Didiagnosa maloklusi angle klas II dental dengan crossbite anterior (over jet : - 2 mm, overbite 5 mm) dan gigi anterior bawah yang berjejal. Pasien dirawat dengan removable inclined plane. Dataran yang miring (inclined plane) akan menstimulasi gerakan ke depan dari insisivus maksila yang crossbite. Gaya dari otot otot memberikan tekanan yang cukup untuk pergerakan insisivus maksila.Setelah 4 bulan perawatan crossbite anterior telah terkoreksi dan perawatan masih dilanjutkan untuk mencapai tujuan perawatan selanjutnya.]]>

<![CDATA[Growth is affected by nutrition contents in the diet consumed.Nutrition playing role in the growth process is carbohydrate, protein, fat, mineral,water, and vitamins. Calcium is one of important minerals involving in cellmetabolism process needed in the process of growth and development. One ofsources of animal calcium is anchovy, besides its cheap price, anchovies may beconsumed wholy together with their bones. The purpose of this study was toobserve whether the supply of anchovies as additional diet may increase thegrowth of male wistars. Methods: A number of 12 male wistars divided into twogroups, control and experimental groups. The control group was only suppliedwith standard diet and sterile aquades, while the other group was supplied withanchovies as additional diet through oral sondage of 0,00062 gr/day x BW (BodyWeigth) for 40 days. Every wistar in each group was subsequently measured forits body length and weigth once a week to observe its growth and development.The data obtained were analized using anova test and LSD orderly. Results: Theresult demostrated the increase in the body length and weigth of the male wistarsof both groups in each week. Anova statistical test that was continued with LSDtest showed that there was significant increase (p<0,05) in the experimental groupin each week compared to the control group. Conclusion: The supply ofanchovies(Stolephorus sp) as additional diet may increase the growth of malewistars body length and weigth.]]>

<![CDATA[Estrogen is a steroid compound that has many benefits for the bodys physiology.Hypoestrogenic women could have periodontitis in their mouth. Hormonereplacement therapy (HRT) is a therapy that used to reduce the disturbance causedby estrogen deficiency. However, HRT has many side effects. Theoretical studyshows that isoflavones in tofu liquid waste has an element of a steroid compound.The purpose of this study was to prove the effectiveness of isoflavones in the tofuliquid waste by examining the microscopic structure, estrogen receptor expressionand MDA levels in rat mandibular bone post-ovariectomy. This research methoduse a true experimental laboratory with randomized post test control group design.Twenty-four female wistar rats were divided randomly into six groups, consistedof a group of normal rat that doesânt ovariectomized (C1), 4 weeksovariectomized rats (C2), 8 weeks ovariectomized rats (C3) but no tofu liquidwaste was given, and 8 weeks ovariectomized rats that given tofu liquid waste atthe end of the 4th week of ovariectomy with three different doses (C4 = 1.2, C5 =6; C6 = 12 ml / kg). Histopathological slide used to see the changes resulted in anumber of osteoclasts, osteocytes, periodontal ligament width, alveolar boneheight, the amount of estrogen receptor expression and MDA levels. The resultsof statistical tests show that there is a difference in the rats between six differentgroups (ANOVA, p <0.05) and there is a close relationship between the dose ofthe tofu liquid waste with all parameter. The conclusion of this study is tofuliquid waste could improve the microscopic structure, estrogen receptorexpression and MDA levels in rat mandibular bone post-ovariectomy.]]>

<![CDATA[The process of tooth extraction can lead to injury. One of the factors that influencethe process of wound healing after tooth extraction is the number of fibroblastcells. The content of saponins can increase the number of fibroblasts cells aftertooth extraction. Asian ginseng plants known to contain saponins (ginsenoside).The purpose of this study was to determine the effect of Asian ginseng extract(Panax ginseng extract) for the increased number of fibroblasts cells after toothextraction. The research method used is in vivo experimental design with thedesign methods Randomized Post Test Only Control Group Design. In this studyused twentty male rattus novergicus and divided into four group, consisting ofcontrol group (K1) were not given Asian ginseng extract, treatment groupsnumber one (K2) were given 25mg/Rattus novergicus/day doses of Asianginseng, treatment groups number two (K3) were given 50mg/ Rattusnovergicus/day doses of Asian ginseng, and treatment groups number three (K4)were given 75mg/Rattus novergicus/day doses of Asian ginseng. Histopathologicpreparations used for counting the number of fibroblasts cells. The results ofstatistical tests indicate there are differences in the number of fibroblast cells inRattus novergicus between the four different groups (ANOVA, p <0.05) and thereis a very strong correlation between increasing doses of ginseng extract with anumber of fibroblast cells in Rattus novergicus tooth socket (Pearson, R = 0.915 p<0.05). The conclusion of this study is Asian ginseng extract can increase thenumber of fibroblasts in the tooth socket after tooth extraction, it is recommendedthat research about the amount of saponin in Asian Ginseng extract]]>

<![CDATA[The main microbial culprit in dental caries is Streptococcus mutans (S.mutans),virulence of which can be observed by its differential protein expression betweencaries and caries-free subjects.The success of Immunoglobulin-Y (IgY) antiS.mutans as a passive immunization agent in eliminating S.mutans has beenreported. The aim of this study is to analyze the effect of IgY anti S.mutans on theprotein expression of S.mutans isolated from caries and caries-free subjects. Eachdental plaque was collected by swabbing the buccal surface of the first lowerpermanent molar of caries and caries-free subjects. The plaques were thencultured on agar medium TYS20B. After 72 hours, the colonies from each of themwere cultured in liquid medium TYS Broth for 72 hour. Each collected bacteria(whether from caries or caries-free subjects) were grouped into control andexposure group. In exposure group, S.mutans was exposed by pre-incubated (forone hour at 37°C) IgY anti S.mutans for one hour at 37°C. Protein expression ofS.mutans was analyzed with SDS PAGE after the preparation of its antigen andBradford protein assay. Our result shows that S.mutans 41.3 kilodalton proteinexpression of caries subjects, are up-regulated in comparison to the control group.Meanwhile, the S.mutans 41.3 kilodalton protein expression of caries-freesubjects, are down-regulated in comparison to the control group. This studysuggests that IgY anti S.mutans up-regulates 41.3 kilodalton protein expression ofS.mutans in the caries subjects. However IgY anti S.mutans down-regulates 4.13kilodalton protein expression of S.mutans in the caries-free subjects.]]>

<![CDATA[Specificity Protein (SP) family members are tissue specific transcription factors.They regulate a wide range of cellular function including cells growth, apoptosis,differentiation and tumor formation. This family composed of more than 25member proteins, which contain a DNA-binding domain very well conservebetween all members with three tandem zinc fingers of the C2H2 type in theirCterminal region. Recently, it has reported in mammalian genome, there are nineSp genes (Sp1-Sp9). Some previous study reported Sp3 knockout mice haveenamel/dentin layer defect. Sp4 mRNA express in E13- E16 of WT mouse incisor.Sp7 mRNA express in at 15, 17 days of post coitum and P1 (postnatal day 1). Sp6has another name epiprofin, I also worked with this genes. Sp6 mRNA expressedin early stage of tooth development to the secretory stage of ameloblast. It alsoreported Sp6 weakly expressed in mesenchymal odontoblast of the incisor. Sp6deficient mice reported delay tooth development. SP family members play animportant role in tooth development.]]>
