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.

Dental Arch Width

Aim: Objectives: To analyze variations in dental arch width in relation to oral habits.   Materials and Methods : Cross sectional  study was carried out Department of Orthodontics & Dentofacial Orthopedics of Dhaka Dental College & Hospital, Dhaka with a total number of 600 primary school children of 3-6 years ages of Bangladeshi population. Results: This study was a cross sectional study conducted among the 600 children with 3-6 years old prima- ry school children of Bangladeshi population. According to present study, bottle feeding causes significant reduction in maxillary intercanine width and mouth breathers show significant reduction of both arches. Conclusion: It was observed that the children who had used a bottle had a significant reduction in maxillary intercanine width. Breathing through mouth appeared to be associated with a reduction in the size of both arches. This was more significant in the maxillary intercanine , mandibular  intercanine and mandibular molar widths. Therefore to prevent malocclusions, the public should be informed of the harm caused by certain oral habits, the benefits of breast-feeding, and the need to correct bad habits at early life.

The implementation of e-filling is a step that the DGT expects to be able to improve individual taxpayer compliance. Many factors that can affect taxpayers are still not compliant in paying or reporting annual tax returns, which is perhaps one of them is understanding taxation. This research is quantitative with the sampling technique used is purposive sampling. The criteria set for taking samples in this study are individual taxpayers who have used e-filling and registered with the South Batam KPP and collected data using questionnaires distributed online and directly to respondents the number of questionnaires distributed was 110 respondents and those who returned and can be processed as many as 105 respondents. The results obtained from this study are (1) the application of e-filling has a significant effect on individual taxpayer compliance with a sig value of 0.038 (2) understanding of taxation has a significant effect on individual taxpayer compliance with a sig value of 0.002 (3) simultaneously the application of e-filling and understanding of taxation have a significant effect on individual taxpayer compliance with a value of sig 0,000. Keywords: Compliance of Individual Taxpayers, Implementation of E-filling, Understanding of Taxation.

Summary Objectives: The diagnostic procedure commences with the initial examination, during which a number of individual findings of the occlusion or malocclusion are clarified [1]. The objective is to describe the morphological and functional characteristics on each patient using specific guidelines, and then to provide a prognosis of the therapy. Upper and lower arch compression in first premolars and molars area was visible before treatment. Methods: A special device (Czech technical university research prototype) was prepared for this purpose. The optical head contains a digital color camera. The front of the optical head consists of a removable prism which is put into the mouth. The findings can display live images from the camera, which can be archived on a PC. The device captured and geometrically calibrated images permitting comparison of several different dental casts. Results: In the first part of this study 792 sets of study plaster casts were screened. Measurements of dental arch width between reference points of canines, first premolars and first molars were made: upper jaw: men: 3-3 – 35.1 mm (SE 0.13); 4-4 – 37.5 mm (SE 0.13); 6-6 – 48.1 mm (SE 0.19); women: 3-3 – 33.4 mm (SE 0.13); 4-4 – 35.6 mm (SE 0.15); 6-6 – 46.7 mm (SE 0.19). The second part concerns the group of 36 patients which is different from the 792 controls. There were studied changes between initial, post-treatment and post-retention alignment of upper and lower dental arch. Conclusions: Geometrically calibrated images help compare several different steps of the treatment and show a significant difference between patients before and after treatment.

Objective: To assess the dental arch forms of Yemeni adult sample. Materials & Method: The Eucledian clustering method of analysis was utilized for the determination of dental arch form. A total of 398 study models were constructed and evaluated to do measurements for both arches using a modified sliding caliper gauge. Six dental cast measurements divided into three sagittal and three transverse measurements were utilized to represent the dental arch width and length measurements. Result: Narrow form is the most prevalent arch form (30.9%) followed by wide form (23.9%), their prominence appear more in females and the least prevalent arch form was the mid form (9.3%), while flat and pointed forms were in between 18.3% and 17.6% respectively. Conclusion: Five arch forms: narrow, wide, mid, pointed and flat were distinguished as unique forms for the dental arches, with the predominance of the narrow arch form were found among Yemeni adults.
