Background Transversal maxillary deficiency corrected with Rapid Maxillary Expander RME may result with some unfavorable side effects and limitations. Maxillary Skeletal Expander MSE , combined with miniscrews, was developed to overcome these drawbacks. This research was conducted to analyze the differences of stress distribution of maxillary expansion using RME and MSE in the Region of Interests ROIs first molars M1 , palatal alveolar bones of M1, palatine sutures, zygomatic sutures, miniscrews and their surrounding bones. Methods A dry skull was scanned using Cone Beam Computed Tomography, and rendered into a three dimensional 3D model of craniomaxillary structure. The data analysis was done visually and numerically. Result The stress distributions in RME group are located in palatal side of M1, mesial side of palatal alveolar of M1, and inferior cortex of palatine sutures. The stress distributions in MSE group are located in distopalatal cusp of M1, palatal side of palatal alveolar of M1, and inferior and superior cortex of palatine sutures. The stress distributions in zygomatic sutures on both groups are concentrated in zygomaticotemporal sutures, whereas in the miniscrews, the stress is concentrated on anterior miniscrews and palatal side of surrounding bones. Conclusion There are significant differences of stress distribution of maxillary expansion measured in the ROIs in craniomaxillary 3D model using RME and MSE."

In addition, corresponding measure meats were also mode is the mesio-distal and bucco palatal teeth. The scores of the carabelli's cups were based on the Dalberg's classification. The results showed that the number of the teeth which had score I with grooves were high (48; 40%), then followed by score 0 (the average of mesio palatal cups) Which comprised of 44 teeth (20%), score 3 (there were depressions shaped as a small "Y" alphabet) were 19 teeth (15,83%), score 5 (there were small cups), score 6 (three were medium cups), score 2 (there were pits) and score 4 (there were depression shaped as big "Y" alphabet which each comprised of the 12 teeth (10%); 7 teeth (5,83%); 6 teeth (5%) and 4 teeth (3,33%). None of the teeth had carabelli's cup with score 7 (there were cups with big size). The results of the measurements on mesio-distal and bucco palatal teeth were variable. The smallest mesio-distal and bucco-palatal teeth were 0,20 mm and the largest were 12,80 mm. In size showed that there was a significant relationship between the teeth size and carabelli's cups which the size of carabelli's cups was always in line the teeth size."

"ABSTRAKMaxillary permanent canines are impacted in about 2% of orthodontic patients, second only in frequency of impaction to third molars. Bringing an impacted canine into the arch creates a set of problems primarily because it is usually a long way from the line of occlusion. Four cases of impacted maxillary canines are presented to show some of the problems encountered during orthodontic traction of these teeth. The cases were treated using a preadjusted edgewise appliances. Careful judgement are needed to treat impacted maxillary canines successfully and to minimize discouraging side effects that often occurs during the procedure."

"This case study reviewed conventional root canal treatment of a maxillary first premolar which unexpectedly had a single canal with two foramens. this tooth was recognized as the least frequent tooth appeared neither with additional canal nor unusual root anatomy. Retreatment for this casewas successfull through widening of the access cavity and the root canal. While trying the master cone, it revealed that the canal splitted and had two foramens. A thorough knowledge of the root canal anatomy as well as careful radiograph interpretations were essential in enhancing the root-cleaning procedure."

Background: Cleft lip and palate is a common congenital disorder that formed during fetal development due to failure of the developmental processes of the face. Three-dimensional (3D) maxillary growth deficiency is often found in patients with cleft lip and palate, particularly in unilateral cases. Patients who had undergone surgical procedures show a decrease on cranial base height, shorter maxilla, severe maxillary retrograntic and more lingual inclination of upper and lower incisor teeth. Multistage treatment is neccessary for patients with the lips and palate such as alveolar bone repair, prosthodontic restoration, and definitive dental correction. Objective: To analyze the effect of labioplasty and palatoplasty to maxillary height, maxillary sinus volume and sella turcica size in patients with unilateral cleft lip and palate. Materials and Methods: Observational analytic study with cross-sectional design. The subjects of this study were children ³13-years-old with unilateral cleft lip and palate, had undergone labioplasty and palatoplasty, and did not undergo fixed orthodontic treatment procedures at RSAB Harapan Kita, Jakarta in the period of 2011-2013. Based on the inclusion and exclusion criteria, a total of 12 subjects were obtained. Each subject took a CBCT radiographic to assess the maxillary height, maxillary sinus volume and sella turcica size. Comparison of maxillary height and maxillary sinus volume was performed on the cleft and normal sides, while the comparison of the size of the sella turcica was performed descriptively using secondary data. Results: There are significant differences in the maxilla height and maxillary sinus volume between the cleft side and the normal side (p = 0.00 and p = 0.01). There is a difference in width and height of the sella turcica between the subject and the control group. Conclusion: Labioplasty and palatoplasty affect maxillary height, maxillary sinus volume and sella turcica size in patients with unilateral cleft lip and palate."

The prevalence of vertical distortion in the periapical radiograph of the anterior maxillary teeth is quite significant and cingulum is commonly used as the reference of vertical distortion in anterior radiograph.

Objective: To evaluate the limit of vertical angulation error that still can be tolerated.

Methods: Periapical radiograph with vertical angle 0° was obtained from 30 maxillary incisors as reference, then the vertical angulation was changed into -10°, +10°, -15°, +15°, -20° and +20°. Long axis of the teeth was adjusted parallel to the film. Tooth length and cingulum width with vertical angulation alteration was measured and compared to the actual length. All of the measurement was tested using T test.

Results: There were no significant differences between all the measurements of tooth length with the alteration in vertical angulation (p>0.05), whereas cingulum width had a significant difference at +15° and -10°, p<0.05.

Conclusion: Tooth length in periapical radiograph of maxillary incisor with parallel position is still tolerable until 20º vertical angle errors. Cingulum width on radiograph with +15º vertical angle alteration is significantly narrowed and on radiograph with -10° vertical angle alteration is significantly widened."

"ABSTRAKLatar Belakang:Teknik conventional two flap palatoplasty akan menimbulkan defek lateral tanpa adanya pelindung periosteum. Defek lateral yang terbuka ini akan menyebabkan rentannya terkena kontaminasi dan infeksi. Hal inilah yang akan menimbulkan kontraksi luka, pembentukan skar dan mengganggu pertumbuhan maxilla.Tahun 2011, terdapat studi mengenai teknik ldquo;The Non Denuded Palatoplasty rdquo;. Teknik ini meninggalkan sebagian periosteum yang diharapkan dapat mempercepat proses epitelisasi pada defek lateral. Epitelisasi yang lebih cepat diharapkan mengurangi terjadinya kontraksi luka dan kedepannya dapat tercapai pertumbuhan maksila yang baik.Metode:Merupakan studi kasus kontrol yang terdiri atas 2 grup membandingkan pertumbuhan maksila pasien dengan celah bibir dan langit-langit unilateral komplit yang dikerjakan dengan teknik conventional ldquo;Two Flap Palatoplasty rdquo; dan teknik ldquo;The Non Denuded Palatoplasty rdquo;. Hasil pengukuran cephalometri dicatat serta dibuat cetakan gigi untuk tiap pasien kemudian dikategorisasi menggunakan metode GOSLON YARDSTICK. Data yang diperoleh dianalisis dengan SPSS versi 20.Hasil:Terdapat 4 pasien di kelompok ldquo;The Non Denuded Palatoplasty rdquo; dan 10 pasien pada teknik conventional ldquo;Two Flap Palatoplasty rdquo;. Hasil pengukuran cephalometri SNA, SNB dan ANB menunjukkan bahwa kedua grup tersebut masuk dalam golongan maloklusi tipe III defisiensi maksila . Sementara hasil GOSLON Yardstick memperlihatkan GOSLON tipe III sebagai kelompok yang sering ditemukan bagi kedua grup dengan reliabilitas inter-rater baik p=0.839 . Pada penelitian ini tidak ditemukan korelasi antara variabel cephalometri dengan skor GOSLON.Kesimpulan:Hasil studi kami menunjukkan bahwa teknik modifikasi ldquo;The Non Denuded Palatoplasty rdquo; tidak berhubungan secara signifikan terhadap pertumbuhan maksila.

ABSTRACTBackground Conventional Two Flap Palatoplasty technique will made lateral defects without any periosteal coverage. These denuded lateral defects are prone to contamination and infection. These will result in wound contraction, scar formation and maxillary growth impairment.In 2011, we studied ldquo The Non Denuded Palatoplasty rdquo technique. This technique precipitated the epithelialization process of the lateral defects. Faster epithelialization is expected to decrease wound contraction and in the long run will result in good maxillary growth.Methods This is a case control study to compare the maxillary growth of 2 groups consists of unilateral cleft lip and palate patients repaired with ldquo The Non Denuded Palatoplasty rdquo technique and Conventional Two Flap Palatoplasty. The outcome will be evaluated from cephalometry and the dental cast for each patient areevaluated using GOSLON YARDSTICK method. Data will be analyzed using SPSS version 20.Results A total of 4 patients in The Non Denuded Palatoplasty group and 10 in the Conventional Two Flap Palatoplasty. The cephalometric SNA, SNB and ANB point showed Class III skeletal jaw relationship or deficient maxilla. While the GOSLON yardstick type III are the frequent GOSLON on both group with good inter ratter reliability p 0.839 based on Mann Whitney test. In these study there were no correlation between cephalometric variables with GOSLON score.Conclusion Our results showed that modification The Non Denuded Palatoplasty technique made no statistically significant difference to the maxillary growth. However this study has several limitations, which are the sample size was small due to family, social and other factors that are beyond the control of the investigating team. Also the age of evaluation 7 9 years , means that the result is not the final outcome. "
