Abstract

Background: Fixed orthodontic treatment needs several types of wire to produce biomechanical force to move teeth. The use orthodontic wire within the mouth interacts with saliva, causing the release of nickel and chromium ions. Purpose: The study was aimed to examine the effect of immersion time in artificial saliva between special type of Australian wire and stainless steel on the release of nickel and chromium ions. Methods: Thirty special type Australian wires and 30 stainless steel wires were used in this study, each of which weighed 0.12 grams. The wires were immersed for 1, 7, 28, 35, 42, and 49 days in artificial saliva with a normal pH. The release of ions in saliva was examined using Atomic Absorption spectrophotometry. Results: The result indicated that the release of nickel ions on special type of Australian wire was larger than that on stainless steel wire (p<0.005), there were differences in the release of the amount of nickel ions on special type of Australia in different immersion time, and there was a correlation between the types of wire and immersion time. Nickel ions released from the special type of Australian wire detected on the 7th day of immersion and reached its peak on the 35th day, while from stainless steel wire were detected on the 49th day of immersion. The released of chromium ions from the special type of Australian wire and stainless steel wire were not detected until the 49th day of immersion. Conclusion: The release of nickel ions were highest on the 35th day of immersion in special type of Australian wire and they were detected on the 49th day in stainless steel wire. The release of chromium ions were not detected until 49th day of immersion in special type of Australian and stainless steel wire.Latar belakang: Perawatan ortodonti cekat memerlukan beberapa macam kawat untuk menghasilkan kekuatan biomekanika yang sesuai dalam menggerakkan gigi. Pemakaian kawat ortodonti di dalam mulut dapat bereaksi dengan saliva sehingga menyebabkan terjadinya pelepasan ion nikel dan kromium.

Abstract

The growth and development of bone play an important role in orthodontics, where bone calcification can be used the estimate bone maturity for diagnosis and treatment planning. Nutritional status during pregnancy and infant period will influence the growth and development of bone. Calcium diet is an important factor determining optimal calcification during bone growth and development stages. The purpose of this study was to investigate the possibility to restore calcium and phosphorus in bone after pre- and postnatal calcium deficiency. Three groups of Rattusnorvegicus rats were used in the experiments. The first group was the control group with standard diet, the second was infant group with pre- and postnatal calcium deficiency, and the third group consisted of young rats at weaning age with pre- and postnatal calcium deficiency but supplemented with enough calcium in the diet. Bone calcification stages were analyzed 1) histologically by measuring epiphyseal width on right femur, 2) by measuring calcium and phosphorus concentration on left femur with spectrophotomethry, atomic absorbtion and UV spectroscopy. The data were analyzed by one way Anova and t testing. The results showed that there were significant differences in the epiphyseal width and in calcium and phophorus concentrations between all three groups (p&lt;0.01). It was concluded that bone calcification damage because of pre- and postnatal calcium deficiency was an irreversible process. Calcium supplement after bone calcification could not restore the condition.

Abstract

The knowledge of the growth and development factors in orthodontics is needed because skeletal manipulations are often done in orthodontic treatment. Because of that, knowledge and understanding of the concept of physiological growth by age especially in the face is needed, apart from growth and development of the teeth. The purpose of this study was to investigate the influence of pre and postnatal calcium deficiency on the density of teeth. Density of teeth was measured by calcium and phosphorus concentration and right incisivus maxilla weight. The study was carried on 30 Rattus norvegicus rats, divided in 3 groups. The first group was fed by a diet without calcium postnatal, the second group was fed by a diet without pre and postnatal calcium, and the third group was fed by standard diet. The concentration of calcium was measured by AAS (Atomic absorption spectrophotometric analysis), the right incisivus maxilla was measured in milligrams, and phosphorus concentration by ultraviolet spectrophotometry. The results of the study showed a significant difference (p&lt;0,01), in calcium and phosphorus concentration and right incisivus maxilla weight between the non calcium fed postnatal, pre-postnatal and the standard groups.

Abstract

Penentuan rencana perawatan ortodontik dengan pencabutan atau tanpa pencabutan masih menjadi perdebatan, terutama pada kasus borderline.Perawatan ortodontik dengan atau tanpa pencabutan dapat mempengaruhi profil wajah.Perubahan pada penampilan wajah terjadi akibat adanya perubahan posisi gigi anterior yang dapat mempengaruhi perubahan profil jaringan lunak wajah terutama pada daerah bibir.Penelitian ini bertujuan mengetahui perbandingan perubahan profil bibir dan posisi gigi insisivus pada kasus borderline klas I antara perawatan dengan pencabutan 4 premolar kedua dan tanpa pencabutan. Penelitian dilakukan pada 28 sefalogram lateral kasus borderline klas I  yang dirawat dengan teknik straight wire, terdiri dari 2 kelompok (13 kasus dengan pencabutan dan 15 kasus tanpa pencabutan).Masing-masing sefalogram dilakukan pengukuran profil bibir,yaitu jarak bibir atas dan bawah terhadapVertical Reference Plane (VRP) dan sudut interlabial; serta posisi gigi insisivus, yaitu jarak gigi insisivus atas dan bawah terhadap Vertical Reference Plane (VRP), sebelum dan sesudah perawatan. Hasil penelitian menunjukkan pada tahap awal perawatan kedua kelompok memiliki karakteristik profil bibir dan posisi gigi insisivus yang sama (p&gt;0,05). Terdapat perbedaan bermakna (p&lt;0,05) pada perubahan posisi bibir, sudut interlabial, dan posisi gigi insisivus antara kelompok yang dirawat dengan pencabutan dan tanpa pencabutan setelah perawatan ortodontik. Kesimpulan penelitian ini adalah profil bibir dan posisi gigi insisivus pada kasus borderline klas I yang dirawat dengan pencabutan 4 premolar kedua menjadi lebih retrusif daripada profil bibir dan posisi gigi insisivus kasus borderline klas I yang dirawat tanpa pencabutan.ABSTRACT, Lips Profile And Incisivus Position In Class Iborder Line Cases With Or Wthout Extraction. Determining whether an orthodontic treatment plan should be with or without extraction is still debatable, particularly for borderline cases. In fact, such a treatment could affect the facial profile. The change in facial appearance is caused by the reposition of anterior teeth which could cause facial soft tissue profile changes, particularly at the lips area. The aim of this study is to compare the changes of lips profile and incisors position in class I borderline cases which have been treated with extraction of 4 second premolars and non-extraction.The study was conducted on 28 lateral cephalograms of class I borderline cases which have been treated with straight wire technique, as divided into two groups (13 extraction and 15 non-extraction cases). Each cephalograms had measured on lips profile, which was the distance of upper and lower lips to Vertical Reference Plane (VRP) and interlabial angle; and the position of incisors, which was the distance of upper and lower incisors to Vertical Reference Plane (VRP), at pre and post-treatment. The results of this study have shown that at the initial treatment, lips profile and incisors position for both groups have similar characteristics (p&gt;0,05). There are significant differences (p&lt;0.05) on lips position, interlabial angle, and incisors position changes between the extraction and non- extractiion cases after orthodontic treatment. From this study, it can be concluded that lips profile and incisors position in class I borderline cases treated with the extraction of second bicuspid are more retruded than that of non-extraction cases

Abstract

Background: Determination of orthodontic treatment plan with or without teeth extraction remains controversial, especially in borderline cases, so it requires more data and information to establish appropriate treatment plans in order to obtain optimal treatment results. Purpose: The study was aimed to determine the facial soft tissue changes in the borderline class I cases treated with and without tooth extraction on post-orthodontic treatment. Methods: The study was conducted on 28 lateral cephalograms, divided into two groups; 13 cases with tooth extraction, and 15 cases without tooth extraction. The subject criterias were as follows; class I malocclusion treated with straightwire technique, skeletal class I, in range of age between 18 to 30 years old, normal overjet 2-4 mm, arch length discrepancy between 2.5 to 5 mm, Index of Fossa Canine (IFC) between 37% to 44%, did not using extraoral devices, and treated with teeth extraction of 4 second premolars or without tooth extraction. The measurement of nasolabial angle, labiomental angle, and linear position of the upper and lower lip to E-Ricketts line were done on each cephalogram before and after orthodontic treatment. Results: In teeth extraction cases, there was a change on upper and lower lips positions (p<0.05), but there were no changes on nasolabial angle and labiomental angle (p>0.05). In non teeth extraction cases, there were no changes in nasolabial angle, labiomental angle, and lips positions (p>0.05). Both of groups also have indicated that there were no changes on linear position of the upper and lower lip (p>0.05). Post-orthodontic treatment indicated a significant differences between extraction and nonextraction cases on nasolabial and labiomental angle, and lips position (p<0.05). Conclusion: The facial soft tissue profile changes on teeth extraction case was more retruded than non- teeth extraction case.Latar belakang: Penentuan rencana perawatan ortodonti dengan pencabutan atau tanpa pencabutan masih menjadi kontroversi, terutama pada kasus borderline, sehingga diperlukan lebih banyak data dan informasi untuk menetapkan rencana perawatan yang tepat agar didapatkan hasil perawatan optimal. Tujuan: Studi ini bertujuan meneliti perubahan profil jaringan lunak wajah sesudah perawatan ortodonti dengan pencabutan dan tanpa pencabutan. Metode: Pengukuran dilakukan pada 28 sefalogram lateral yang terdiri dari 2 kelompok, yaitu 13 sefalogram lateral untuk kasus dengan pencabutan gigi dan 15 sefalogram lateral untuk kasus tanpa pencabutan gigi. Kriteria subjek penelitian adalah maloklusi klas I yang dirawat dengan teknik straightwire, hubungan skeletal klas I, berusia 18–30 tahun, overjet normal antara 2–4 mm, diskrepansi panjang lengkung antara 2,5–5 mm, Indeks Fossa Canina (IFC) antara 37%-44%, tidak menggunakan alat ekstraoral, dan perawatan dengan pencabutan 4 premolar kedua atau tanpa pencabutan. Pada tiap sefalogram dilakukan pengukuran sudut nasolabial, sudut labiomental, dan pengukuran linier posisi bibir atas dan bawah terhadap garis E Ricketts sebelum dan sesudah perawatan ortodonti. Hasil: Pada kelompok pencabutan terdapat perubahan posisi bibir atas dan bawah terhadap garis E Ricketts (p<0,05), namun tidak terdapat perubahan sudut nasolabial dan sudut labiomental (p>0,05). Pada kelompok tanpa pencabutan tidak terdapat perubahan pada sudut nasolabial, sudut labiomental, dan posisi bibir (p>0,05). Terdapat perbedaan sudut nasolabial, sudut labiomental, dan posisi bibir antara kelompok dengan pencabutan dan tanpa pencabutan sesudah perawatan ortodonti (p<0,05). Simpulan: Profil jaringan lunak wajah kelompok yang dirawat dengan pencabutan gigi menjadi lebih retrusi daripada profil jaringan lunak wajah kelompok yang dirawat tanpa pencabutan.
