"Orthodontic medical treatment is performed to move a tooth to the optimal position to obtain optimal occlusion. Orthodontic treatment is accompanied by mechanical stress due to orthodontic force and by psychological stress that is experienced as pain or displeasure. The purpose of this study was to identify stress marker proteins during orthodontic treatment. Levels of receptor activator of NFκB (RANKL) and heat shock protein 70 (HSP70) in the gingival crevicular fluid (GCF) were analyzed as markers of mechanical stress, and levels of chromogranin A (CgA) and amylase in whole saliva were analyzed as markers of psychological stress. GCF was collected from control and experimental teeth at initiation of treatment and 24 h after treatment. Whole saliva was collected before treatment, at initiation of treatment and 24 h after treatment. RANKL was expressed at 24 h after treatment in the experimental GCF, but not in the control GCF. HSP70 appeared to be constitutively expressed in GCF, and its levels showed no major change between the control and experimental groups from initiation of treatment to 24 h after treatment. Amylase activity in whole saliva was enhanced at 24 h after treatment compared to control, but CgA levels showed little change between the groups. These results indicated that RANKL and amylase may be the candidate markers for mechanical and psychological stress, respectively, during orthodontic treatment, even though the total protein concentration and amylase activity displayed a large standard deviation among subjects. Further studies are therefore required to establish these markers for clinical use."

"Objectives: (1) To assess the masticatory muscles activity in patients with Temporomandibular Disorder (TMD) before orthodontic treatment, (2) to determine the correlation between TMD and the masticatory muscles activity (masseter muscles and anterior temporalis muscles). Methods: Twenty-two patients with malocclusion before undergoing orthodontic treatment (8 males, 14 females; mean age of 26,78 ± 4.34 years) were enrolled in the study and were divided into two groups: 11 patients with TMD and 11 patients without TMD (Non- TMD). The masticatory muscles were evaluated using standardized electromyography during 5 seconds of maximum voluntary contraction (MVC) through cotton-roll biting. For statistical analysis, the root mean square (RMS) valueof masticatory muscles was calculated and compared between the two groups. Results: The TMD groups showed alower electromyographic activity than the non- TMD group during MVC, with no significant differences in the right and left masticatory muscles between these groups. A weak negative correlation and no statistically significant differences were found between TMD and the electromyography activity of masseter muscles. Conclusions: Patients with TMD had a lower electromyographic activity in the masticatory muscles than those without TMD. Thus, electromyography can be an objective parameter to assess muscles activity for TMDdiagnosis.

Background: The etiology of orthodontically induced inflammatory root resorption OIIRR is considered to be multifactorial, one of them is bracket system. Passive self ligating SL and preadjusted edgewise appliance PEA bracket systems are most frequently used in recent time. Dentin sialoprotein DSP in gingival crevicular fluid GCF could be suitable for monitoring OIIRR at initial stage.

Aim: Analyzing differences of DSP concentration related to OIIRR after initial orthodontic treatment using passive SL and PEA bracket system.

Methods: Two experimental orthodontic groups passive SL or PEA and one control group, with six patients on each group, were participated in this study. The inclusion criteria Little's irregularity index on maxillary anterior teeth ranging from 4 9 mm, no active dental caries and periodontitis. GCF collection was done at baseline, also at 3 and 12 weeks of orthodontic treatment. DSP concentration in GCF was assessed by enzyme linked immunoabsorbent assay.

Results: Both bracket systems showed insignificant increase of DSP concentration p 0.060 during 3 and 12 weeks of orthodontic treatment. There is no significant difference of DSP concentration between both bracket systems during experimental period p 0.211.

Conclusion: Three and twelve weeks of orthodontic treatment using passive SL and PEA bracket system showed insignificant increase in DSP concentration."

"Fase awal pergerakan gigi ortodontik diawali dengan respon inflamasi akut. Proses ini menimbulkan respon dari sel paradental dan sel pertahanan tubuh dengan mensintesis dan melepaskan berbagai biomolekul seperti sitokin. Tumor necrosis factor-a TNF-? merupakan sitokin pro-inflamasi penting yang meregulasi respon awal inflamasi pada pergerakan gigi ortodontik. Tujuan dari penelitian ini adalah untuk menganalisis ekspresi TNF-? dengan membandingkan konsentrasinya pada gingival crevicular fluid GCF antara sistem self-ligating SL dan preadjusted edgewise appliance PEA pada tahap awal perawatan. Metode: Delapan belas pasien usia 15-35 tahun yang berpartisipasi dalam penelitian ini dibagi menjadi dua kelompok eksperimental PEA dan SL dan satu kelompok kontrol tanpa perawatan ortodontik. Pasien dipilih berdasarkan kriteria inklusi: indeks iregularitas Little sebesar 4-9 mm pada anterior maksila dengan indikasi perawatan non-ekstrakasi serta tanpa karies aktif, penyakit periodontal, dan penyakit sistemik terkait kerusakan tulang. Cairan krevikular gingiva subjek diambil pada lima titik di anterior maksila sebelum perawatan dan pada: 1, 24, dan 168 jam setelah aplikasi gaya ortodontik. Konsentrasi TNF-? pada sampel GCF diperiksa menggunakan metode enzyme-linked immunoabsorbent assay ELISA. Hasil: Konsentrasi TNF-? meningkat pada 1 jam dan 24 jam setelah aplikasi gaya ortodontik pada kedua sistem baik pada kelompok SL dan PEA. Konsentrasi TNF-? menurun signifikan pada 168 jam setelah aplikasi gaya ortodontik pada kelompok PEA. Sementara itu, pada kelompok SL konsentrasi TNF-? pada 168 jam tetap meningkat walaupun secara statistik tidak signifikan. Kesimpulan: Konsentrasi TNF-? meningkat pada 1 jam dan 24 jam setelah aplikasi gaya ortodontik pada kelompok PEA dan SL. Pada kelopok PEA, konsentrasi TNF-? menurun signifikaan pada 168 jam, sedangkan pada kelompok SL konsentrasi TNF-? tetap meningkat. Perbedaan konsentrasi TNF-? antara kelompok PEA dan SL mungkin disebabkan oleh perbedaan braket, kawat, dan sistem ligasi yang digunakan antara kedua sistem tersebut.

The early phase of orthodontic tooth movement begins with acute inflammation response. This processes engender a response on the part of paradental cells and migrating inflammatory cells from periodontal ligament capillaries via the synthesis and release of various biomolecules such as cytokines. Tumor necrosis factor a TNF is an important pro inflammatory cytokine that regulates the early phase of inflammation reaction during orthodontic tooth movement. The aim of the present study was to analyze TNF expression by comparing its concentrations in the gingival crevicular fluid GCF between self ligating SL and preadjusted edgewise appliance PEA systems during the early levelling stage of orthodontic treatment.

Methods: Eighteen patients aged 15 35 years who participated in this study were divided into two experimental groups PEA and SL and control group without orthodontic treatment. Patients were selected according to the inclusion criteria Little irregularity index on maxillary anterior teeth ranging from 4 9 mm non extraction orthodontic treatment for the experimental group no active dental caries, periodontitis, and medical history of bone disorder. The GCF was taken at five sites in the maxilla anterior teeth from each subject just before bracket bonding and at 1, 24, and 168 hours after orthodontic force application. TNF levels in GCF were determined by enzyme linked immunoabsorbent assay ELISA.

Results: The concentration of TNF was significantly higher in the experimental groups than in the control group at 24 hours after force application. TNF levels were significantly decreased at 168 hours after force application in the PEA group. Meanwhile, in the SL group, the level of TNF at 168 hours was still increased, although there was no statistically significant difference.

Conclusion: TNF concentration was increased at 1 hour and 24 hours after orthodontic force application in both the PEA and SL groups. In the PEA group, TNF concentration was significantly decreased at 168 hours, meanwhile in the SL group, this value remained increased at this time point. The differences in TNF concentration between the PEA and SL groups may be caused by their different types of brackets, wires, and ligation methods."
