"Tujuan: Penelitian ini bertujuan menganalisis perbedaan besar friksi kinetik antara kombinasi braket Stainless Steel (SS) Edgewise slot .018 dan kawatSS .017X.025, dengan kombinasi braket slot .022 dan kawat SS.019X.025 pada saat pergerakan sliding gigi kaninus. Metode: Penelitian laboratoris ini terdiri dari 96 sampel yang terbagi atas dua kelompok slot braket, dan setiap kelompok slot braket terbagi atas empat kelompok beban tahanan. Besar friksi kinetik diukur dengan Universal Testing Machine merk ChatillonTM pada kedua kelompok slot braket saat pergerakan sliding gigi kaninus yang diberi beban tahanan 0, 50 gr, 100 gr, dan 150 gr. Hasil: Friksi kinetik pada kelompok braket slot .018 lebih besar daripada slot .022 secara bermakna pada kelompok beban tahanan 0, 50 gr, dan 100 gr, namun tidak bermakna pada kelompok beban tahanan 150 gr. Besar friksi kinetik meningkat secara bermakna seiring peningkatan besar beban tahanan 50 gr, 100 gr, dan 150 gr pada kedua kelompok slot braket. Kesimpulan: Friksi kinetik pada kombinasi braket SS Edgewise slot .018 dan kawat SS .017X.025 terjadi lebih besar daripada kombinasi braket slot .022 dan kawat SS .019X.025.

Objectives: The objective of this study was to compare kinetic frictional force of Stainless Steel (SS) Edgewise bracket between .018 slot coupled with .017X.025 SS wire and .022 slot coupled with .019X.025 SS wire in simulated sliding canine movement.

Methods: This in-vitro study was done to measure kinetic frictional force of 96 samples, divided into two bracket slot groups and each of bracket slot groups was divided into four retarding force groups. Kinetic frictional force was measured byChatillonTM UniversalTesting Machine for both bracket slot groups, in simulated sliding canine movement using 0, 50 gr, 100 gr, and 150 gr retarding forces.

Results: Kinetic frictional force was significantly greater for the .018 than .022 bracket slot in the 0, 50 gr, and 100 gr retarding force groups, but it was not significant in the 150 gr retarding force group. Frictional force increased with the increasing of the 50 gr, 100 gr, and 150 gr retarding forces for both bracket slot groups.

Conclusions: Kinetic frictional force of the .018 SS Edgewise bracket slot coupled with .017X.025 SS wire is greater than the .022 bracket slot coupled with .019X.025 SS wire."

"[Tujuan: Penelitian ini bertujuan untuk mengetahui perbedaan persepsi ortodontis dan orang awam Indonesia terhadap posisi bibir pada profil wajah orang Indonesia ras Deutero-Malayid. Metode: Posisi bibir pada foto profil wanita ras Deutero-Malayid dimodifikasi secara digital dalam arah anteroposterior terhadap garis E Ricketts sehingga diperoleh tujuh posisi bibir. Ketujuh foto ini kemudian dinilai oleh 24 ortodontis dan 24 orang awam wanita ras Deutero-Malayid berusia 25-55 tahun. Penilaian dilakukan dengan metode Visual Analogue Scale (VAS) dan pemilihan satu posisi bibir yang paling disukai. Hasil: Perbedaan persepsi ortodontis dan orang awam yang bermakna dapat ditemukan pada penilaian VAS posisi bibir atas -2 mm dan posisi bibir bawah 0 mm; posisi bibir atas +4 mm dan posisi bibir bawah +6 mm; sertaposisi bibir atas +6 mm dan posisi bibir bawah +8 mm. Baik ortodontis maupun orang awam memilih posisi bibir atas -2 mm dan posisi bibir bawah 0 mm sebagai posisi bibir yang paling disukai. Kesimpulan: Terdapat perbedaan persepsi ortodontis dan orang awam terhadap posisi bibir pada profil wajah dalam hal kekritisan penilaian namun terdapat kesamaan pemilihan posisi bibir., Aim: The aim of this study was to compare the perception of Indonesian orthodontists and laypersons to various lip positions in Indonesian Deutero-Malayid facial profile. Method: The lip position in a female Deutero-Malayid profile photo was digitally adjusted in anteroposterior direction from Ricketts' E-line to obtain seven lip positions. These seven photos were then assessed by 24 female orthodontists and 24 female laypersons (25-55 years). Assessment were done with Visual Analogue Scale (VAS) and selection of the most preferred lip position. Result: Significant differences between perception of orthodontists and laypersons were found for upper lip -2 mm and lower lip 0 mm; upper lip +4mm and lower lip +6 mm; upper lip +6 mm and lower lip +8 mm. Orthodontists and laypersons selected upper lips -2 mm and lower lips 0 mm as the most preferred lip position. Conclusion: There were significant differences between orthodontists' and laypersons' perception regarding evaluation criticality toward lip positions in facial profile. However, both groups show same preference for lip position.]"

"[ABSTRAKPendahuluan: Pengukuran indeks PAR umumnya dilakukan secara manual. Seiring dengan perkembangan teknologi, maka dikembangkan piranti lunak indeks PAR untuk membantu ortodontis dalam mengukur indeks PAR secara digital. Tujuan: Penelitian ini bertujuan membandingkan hasil pengukuran skor indeks PAR (komponen 1-6) secara manual dan digital. Material dan Metode:Enam puluh subyek penelitian yang sesuai kriteria inklusi dilakukan pemindaian dengan menggunakan alat pindai datar/scanner HP Scanjet G4050 sehingga didapatkan model studi digital dua dimensi (2D). Dilakukan pengukuran skor indeks PAR (komponen 1-6) secara manual pada model studi konvensional dengan menggunakan penggaris plastik PAR dan pengukuran secara digital pada model studi digital 2D dengan menggunakan piranti lunak indeks PAR.Hasil: Tidak terdapat perbedaan bermakna antara pengukuran skor indeks PAR (komponen 1-6) pada model studi konvensional dengan model studi digital 2D (p>0,05).Kesimpulan: Pengukuran pada model studi digital 2D sama akurat dengan model studi konvensional.

ABSTRACTIntroduction: Over the years, PAR index measurement is usually recorded using manual assessment. Along with the technology improvements, PAR index software are being developed to help orthodontists in measuring the PAR index digitally.Objectives: The aim of this study is to compare the result of PAR score index (component 1-6)between the manual and digital measurement.Materials and Methods: Sixty samples that match the inclusion criteria were scanned using HP Scanjet G4050 scanner device to obtain 2D digital study models. Manual measurements of the PAR score index (component 1-6) was assessed using PAR plastic ruler, while the 2D digital study models were measured using PAR index software.Results:There were no significant differences between the measurement of PAR score index (component 1-6) in conventional and 2D digital study models (p>0,05).Conclusions: The measurements on 2D digital study models are as accurate as conventional study models., Introduction: Over the years, PAR index measurement is usually recorded using manual assessment.
