Ukuran dan bentuk lengkung gigi rahang bawah pada orang Papua

Abstract: Mandibular size and shape are important information especially in terms to figure out the right diagnosis and the type of treatment a patient should have. Human mandible is a key factor for occlusion adjustment, meanwhile maxilla is following the mandible’s position. Several studies show that the stability of mandibular shape and size determines the success of one’s treatment. Each ethnic group has a particular skeletal pattern as well as shape and size of mandible. This study was aimed to obtain the average size and shape of mandibles among local Papuans. This was a descriptive observational study with a cross-sectional design. Samples were obtained by using purposive sampling method. There were 35 local Papuans aged 18-25 years as subjects. Data were obtained by molding the subject’s mandible, therefore, each subject produced a study model. The study model was measured in sagittal (length) and transversal (width) views based on Raberin method. The results showed that the average lengths of local Papuans’ mandibular size in sagittal view (L31, L61, and L71 in a row) were 6.143; 26.463; and 43.743 mm meanwhile the average widths of local Papuans’ mandibular size (L33, L66, and L77 in a row) were 30.857; 50.971; and 60.971 mm. The mandibular shape of most local Papuans was mid shape (45.8%) meanwhile the least shape of them was pointed (5.7%)Keywords: dental arch size, dental arch shape, mandibular, local Papuan Abstrak: Ukuran dan bentuk lengkung gigi rahang bawah sangat diperlukan dalam menentukan diagnosis dan rencana perawatan yang tepat dalam bidang ortodontik karena rahang bawah merupakan faktor stabilitas oklusi, sedangkan rahang atas menyesuaikan pada rahang bawah. Beberapa peneliti menyatakan bahwa kestabilan bentuk dan ukuran lengkung gigi rahang bawah merupakan faktor stabilitas dari hasil perawatan. Setiap kelompok etnik cenderung memiliki pola skeletal dan ukuran lengkung gigi rahang bawah yang berbeda. Penelitian ini bertujuan untuk mengetahui rerata ukuran dan bentuk lengkung gigi rahang bawah pada orang Papua. Jenis penelitian yaitu deskriptif observasional dengan desain potong lintang. Subjek penelitian ini sebanyak 35 orang Papua berusia 18-25 tahun diperoleh dengan menggunakan teknik purposive sampling. Pengambilan data dalam penelitian dilakukan dengan mencetak rahang bawah setiap subjek penelitian dan didapatkan hasil cetakan berupa model studi. Model studi yang diperoleh diukur dalam arah sagital (panjang) dan transversal (lebar) berdasarkan metode Raberin. Hasil pengukurun diperoleh rerata panjang lengkung gigi rahang bawah pada orang Papua dalam arah sagital (yaitu L31, L61, L71) berturut-turut 6,143; 26,463; dan 43,743 mm, sedangkan rerata lebar lengkung gigi dalam arah transversal (yaitu L33, L66, L77) berturut-turut 30,857; 50,971; dan 60,971 mm.

Abstrak Latar Belakang: Dalam proses Bounding Attachment ada beberapa faktor yang mempengaruhi, diantaranya Sibling Rivalry atau Perilaku anak ataupun bayi dengan keluarga yang dapat tumbuh dari diri anak itu sendiri dan orang tua dalam mendidik. perlakuan orang tua terhadap anak merupakan faktor kunci yang menentukan seberapa besar persaingan yang terjadi antara saudara kandung. Respon anak pertama terhadap adik bayinya dapat mempengaruhi proses bounding attachment, bayi akan merasa terganggu dengan cara menangis. Jika terjadi berulang-ulang, maka tujuan bounding attachment yang mengharapkan bayi dapat mengadakan eksplorasi menjadi terbatas, sehingga menumbuhkan sikap sosial berkurang, dan menumbuhkan perilaku meniru sikap kakaknya. Faktor yang paling dominan terjadinya sibling rivalry pada anak yaitu sikap orang tua. Orang tua membagi perhatian dengan orang lain, mengidolakan anak tertentu, perasaan kesal, dan membanding-bandingkan anak dapat memicu terjadinya sibling rivalry. perlakuan orang tua yang adil dapat menjalin Kedekatan emosi orang tua dengan anak sehingga akan slalu memiliki ikatan batin (kasih sayang) yang kuat. Tujuan: Diketahuinya Hubungan Sibling Rivalry dengan Bounding Attachment pada Ibu Nifas di Desa Bae Kudus. Metode: Jenis penelitian analitik korelasi dengan pendekatan cross sectional, dengan popuasi 52 responden. Dengan accidental sampling sebesar 46 responden. Pengambilan sampel dengan cara purposive sampling menggunakan kriterian inklusi dan eksklusi dengan alat uji menggunakan chi square (X2) dengan menggunakan dan 95% confidence intervel (CI). Hasil: Hasil uji chi square Sibling Rivalry Dengan Bounding, Sibling Rivalry Dengan Bounding Attachment diperoleh nilai p value sebesar= 0,027. Kesimpulan: Ada Hubungan Sibling Rivalry Dengan Bounding Attachment Pada Ibu nifas di Desa Bae Kudus. Kata kunci : Sibling Rivalry, bounding attachment Abstract Background: In the Bounding Attachment process, there are several factors influencing the process including Rivalry Sibling or the behavior of child or baby with family that can grow from the child himself and the parents in giving education. Parental treatment to children is a key factor that determines the competition occuredamong the siblings. The first child's response to youger sister (baby) can affect the process of bounding attachment in the way that the baby will be disturbed by crying. If it happens repeatedly, the goal of bounding attachments that the baby will carry out exploration becomes limited, therefore it will reduce social attitudes and imitate his brother's attitude.The most dominant factor in sibling rivalry is the attitude of parents. This means that parents share attention with others, idolize certain children, feel upset with certain children, and compare children so that it may trigger sibling rivalry. Fair parental treatment will create close emotional betweenparents and children so that they will always have a strong inner bond (love). Objective: this study is to know the relationship between Sibling Rivalry and Bounding Attachment in Postpartum Mothers in Bae of Kudus. Method: This study used analytical correlation research with cross sectional approach. The population were 52 respondents. Taken accidental sampling, the samples were 46 respondents. Sampling was done by purposive sampling using inclusion and exclusion criteria of chi square (X2) test using 95% confidence intervals (CI). Results: The results of chi square test of Sibling Rivalry With Bounding, Sibling Rivalry with Bounding Attachment obtained p value of = 0.027. Conclusion: There is relationship between Sibling Rivalry and Postpartum Bounding Attachment in Bae Kudus Keywords: Sibling Rivalry, bounding attachment

Dental Arch Length

Background: Dental arch form and dimension are fundamental factors in orthodontic diagnosis and treatment planning. Its dimension will increase, due to the eruption of teeth, and is also affected by ethnicity, nutrition, systemic disease, hormonal factors, and gender. Many teeth are erupting in 8–10-year-old children. Purpose: This study aimed to assess the correlation between age and dental arch dimension of Javanese children in good nutritional status for consideration of orthodontic treatment. Methods: This was a cross-sectional study with 66 children aged 8–10 years in a normal dentoskeletal relationship, grouped based on age as the subject. Each group consisted of 22 pairs of dental study models, male and female. Anterior and posterior size of dental arch length were measured by digital sliding calipers from the midpoint between the right and left permanent central incisors perpendicular to the inter-canines and inter-molars. The width was measured at the inter-canines and inter-molars. Results: Pearson’s correlation test showed that there were significant correlations between age and maxillary dental arch lengths (p = 0.01, r = 0.31 for anterior, and p = 0.043, r = 0.249 for posterior). Conclusion: Based on this study, it can be concluded that there was a positive correlation between age and dental arch length of 8–10-year-old Javanese children in good nutritional status, especially in maxillary dental arch length.

Pendahuluan: Gigi berjejal adalah salah satu kasus maloklusi yang sering dikeluhkan oleh pasien dalam perawatan ortodonti, khususnya pada regio anterior. Sekrup ekspansi adalah salah satu komponen aktif dalam alat ortodonti lepasan yang digunakan untuk melebarkan lengkung gigi dalam kasus gigi berjejal. Keberhasilan perawatan dengan sekrup ekspansi dapat dievaluasi dengan mengukur lebar interkaninus. Evaluasi ini dapat dilihat dalam satu sampai tiga minggu setelah aktivasi. Penelitian ini bertujuan untuk menganalisis perubahan lebar interkaninus rahang bawah setelah aktivasi sekrup ekspansi pada perawatan ortodonti lepasan dengan membandingkan waktu aktivasi dua dan tiga minggu sekali. Metode: Jenis penelitian ini adalah analitik cross-sectional dengan teknik pengambilan sampel secara purposive sampling. Pengumpulan data dilakukan dengan cara mengukur lebar interkaninus pada 18 model studi rahang bawah pasien sebelum dan setelah sepuluh kali aktivasi sekrup ekspansi pada kelompok waktu aktivasi dua dan tiga minggu sekali di Klinik Ortodonti RSGM Unpad. Data dianalisis dengan uji t menggunakan aplikasi SPSS 23. Hasil: Lebar interkaninus rahang bawah mengalami perubahan secara bermakna pada kelompok waktu aktivasi tiga minggu sekali, yaitu sebesar 1,38 mm, yang dua kali lebih besar daripada kelompok waktu aktivasi dua minggu sekali, yaitu sebesar 0,6 mm, dengan p<0,05. Nilai standar deviasi dari seluruh data terbilang kecil, menunjukkan bahwa data bersifat homogen. Simpulan: Perawatan ortodonti menggunakan sekrup ekspansi rahang bawah menunjukkan tidak terdapat perubahan yang bermakna pada kelompok waktu aktivasi dua dan tiga minggu sekali, namun secara klinis aktivasi lebih efektif apabila dilakukan lebih dari dua minggu sekali.Kata kunci: Sekrup ekspansi, lebar interkaninus, rahang bawah. ABSTRACTIntroduction: Tooth crowding is a malocclusion case often complained in orthodontic treatment, especially in the anterior region. The expansion screw is one of the active components in a removable orthodontic appliance used to enlarge the dental arch in cases of tooth crowding. The success of treatment with expansion screws can be evaluated through intercanine width measurement. This evaluation can be seen within one to three weeks after activation. This study was aimed to analyse changes in mandibular intercanine width after expansion screw activation in removable orthodontic treatment by comparing the activation times in the second and third weeks. Methods: This research was cross-sectional analytic with a purposive sampling technique. The data was collected by measuring the intercanine width in 18 study models of the patient’s mandible before and after ten expansion screw activation in the second and third-week activation time group at the Orthodontics Clinic of Universitas Padjadjaran Dental Hospital. Data were analysed by t-test using SPSS 23 software. Results: The mandibular intercanine width experienced a significant change in the third-week activation time group, which was 1.38 mm, twice larger than the second-week activation time group, which was 0.6 mm, with p<0.05. The standard deviation value of all data was relatively small, indicating that the data was homogeneous. Conclusion: Orthodontic treatment using mandibular expansion screw showed no significant changes in the second and third week activation time groups. However, clinical activation is more effective if performed more than once every two weeks.Keywords: Expansion screw, intercanine width, mandible.

Background: Using erupted components of a dental arch to estimate the width of the unerupted dental components are the basis of mixed dentition analysis. Non-radiographic mixed dentition analysis employs a regression equation to assess the width of the unerupted canines and premolars. In this study, we assessed the applicability of two non-radiographic methods of mixed dentition analysis in orthodontic patients. Methods: This cross-sectional research was carried out from the records of Ziauddin College of Dentistry, Department of Orthodontics, from November 2019 to March 2020. Pre-treatment dental casts of 120 subjects (60 males and 60 females) aged between 12-30 years undergoing orthodontic treatment were selected. The mesiodistal widths from the left first molar to the right first molar were measured using a digital Vernier caliper on pretreatment dental casts of both arches. Bachman’s and Tanaka-Johnston methods were applied to estimate the widths of canine and premolars. Gender dimorphism for actual and estimated values was assessed using an independent t-test and a paired t-test was applied for the comparison between the actual and estimated mesiodistal widths of canine and premolar. Results: The actual and estimated widths of canine and premolars reported 14.3±1.4 years for males and 13.4±1.2 years for females. In addition, the Bachman’s and Tanaka-Johnston method overestimated the actual widths of unerupted canine and premolar but the difference was statistically insignificant (p≥ 0.05) in both the genders. Conclusion: The two non-radiographic methods were reliable for mixed dentition analysis with minor overestimation between actual and estimated widths (ICC=0.79). This makes both the methods applicable interchangeably in regular clinical practice.

Saliva merupakan salah satu komponen penting yang berperan dalam melindungi jaringan di dalam rongga mulut. Namun, setiap individu memiliki laju aliran dan pH saliva yang berbeda-beda karena dipengaruhi oleh berbagai faktor salah satunya terhadap stimulus mekanis seperti pada pemakaian pesawat ortodonti cekat. Penelitian ini bertujuan untuk membandingkan laju aliran dan pH saliva pasien dengan piranti ortodonti cekat dan tanpa piranti ortodonti pada mahasiswa FKG USU. Jenis penelitian ini adalah cross sectional. Pemilihan sampel dilakukan dengan cara purposive sampling dan sampel yang diambil sebesar 44 orang yang terdiri dari 22 orang pemakai piranti ortodonti cekat dan 22 orang bukan pemakai piranti ortodonti. Pengumpulan saliva dilakukan dengan metode passive drool. Perbandingan laju aliran saliva antara kedua kelompok dianalisis menggunakan uji Mann – Whitney U dan perbandingan pH saliva dengan menggunakan uji-t independent. Hasil penelitian menunjukkan bahwa laju aliran saliva tertinggi sebesar 1,16 ml/menit dan pH saliva tertinggi sebesar 7,60 terdapat pada pasien pemakai piranti ortodonti cekat dan laju aliran terendah 0,08 ml/menit dan pH saliva terendah 6,40 pada pasien tanpa piranti ortodonti cekat. Sebagai kesimpulan, terdapat perbedaan yang signifikan untuk laju aliran dan pH saliva antara pasien dengan piranti ortodonti cekat dengan pasien tanpa piranti ortodonti (p<0,05), dimana laju aliran dan pH saliva pada pasien dengan piranti ortodonti cekat lebih tinggi dibandingkan dengan pasien tanpa piranti ortodonti.
