Determination of Orthodontic Treatment Need for Individuals in Pubertal Growth Period and Effects of Different Variables on the Treatment Needs with Using the ICON Index

Aim:To evaluation of orthodontic treatment need for individuals who are in pubertal growth period with using the ICON index and whether treatment need change according to gender, dental, sagittal and vertical skeletal malocclusions.Subjects and Method:In this study, pretreatment orthodontic casts and panoramic films of 138 patients (75 females, 63 males and mean age 13.8 ± 1,2) were investigated by using ICON index.Results:91 of 138 patients (%65,9) were found to be need for orthodontic treatment. Although it is not statistically significant, females in genders (%69,3), Class III patients in dental malocclusions % 71,4), and Class I and Class III anomalies in sagittal skeletal malocclusions were found higher than the others. Also, in vertical skeletal malocclusions, orthodontic treatment needs of hyper-diverjant patients % 79,3) were found statistically higher than the others.Conclusion:The majority of individuals who were in pubertal growth period were female (% 54,3), dental Class II (% 70,3), skeletal Class I malocclusion (%55,8) and normo-diverjant (%47,8). It was seen that when the vertical direction growth increased, the need for orthodontic treatment increased. As a result, studies about indexes should be done for comparison, sharing and proliferation of new information, and patients determination for orthodontic treatment should be done according to treatment needs rather than Angle classifications

Araştırmanın Somalililere Türkçe öğretimine ve yabancı dil olarak Türkçe öğretimi alanına katkı sağlayacağı düşünülmektedir.The aim of this research is to detect and classify the presence of verbs in the oral narratives of Somali students learning Turkish, to detect errors in the use of morphological claims that verbs have taken, and to suggest solutions. In the research, 25 Somali students studying at Bursa Uludağ University were asked to make oral expressions on various subjects. The existence of verbs in these expressions has been determined and classified. In addition, it was determined what kind of mistakes were made regarding the use of verbs and suggestions were made about what should be done in order to prevent and correct mistakes in order to ensure permanent learning. According to the results of the research, it was determined that Somali students used 546 different verbs in their oral narratives, and in the classification of these verbs as content, 46% were verbs expressing occurrence, 39% were verbs expressing behavior, and 15% were verbs expressing status. In addition, in the classification of verbs, 40.48% of the verbs used by Somali students in their oral narratives are compound, 37.55% are derived and 21.97% are root verbs. In the findings of the use of the verbs used by the Somali students, it was determined that while 54% of the verbs used, errors were not made, while 46% were wrong. In addition, it was determined that all the students participating in the research made morphological prompt errors in their oral narratives. 54.65% of the mistakes made are subtraction, 39.75% of them are changing and 5.60% are additions. The most frequently mistaken status suffixes are the state of specifying with 37.42%, orientation with 31.39%, presence with 11.53%, vehicle status with 8.88%, separation with 5.18%, 4%, It has been determined that there is a plain condition with 02 and a condition without appendix with 1.59%. In addition, these findings are detailed and exemplified under various sub-headings. It is thought that the research will contribute to the teaching of Turkish to Somalis and to the field of teaching Turkish as a foreign language

Dens evaginatus on maxillary first premolar: Report of a rare clinical case

Dens evaginatus (DE) is an odontogenic developmental anomaly that can be defined as a tubercle or protuberance from the involved surface of the affected tooth consisting of an outer layer of enamel, a core of dentin, and may contain a slender extension of pulp tissue. Early diagnosis and management of DE is important in order to prevent occlusal interference, compromised esthetics, carious developmental grooves, periodontal problems due to excessive occlusal forces, or irritation of the tongue during speech and mastication. DE usually affects the mandibular second premolars as an accessory cusp or a protuberance between the buccal and lingual cusps. Reports of DE on maxillary premolar are rare in the literature. We report one such extremely rare case of DE on maxillary first premolar

The Effect of Changes in Lower Incisor Inclination on Gingival Recession

Aim. Orthodontic treatment may promote development of recessions. The mechanism by which orthodontic treatment influences occurrence of recessions remains unclear. The aim of this study was to test the hypothesis that a change of mandibular incisor inclination promotes development of labial gingival recessions. Materials and Methods. The study sample comprised dental casts and lateral cephalograms obtained from 109 subjects before orthodontic treatment (Tb) and after orthodontic treatment (Ta). Depending on the change of lower incisor inclination during treatment, the subjects were divided into three groups: Retroclination (R), Stable Position (S), and Proclination (P). The presence of gingival recessions of mandibular incisors and clinical crown heights were assessed on plaster models. Results and Conclusions. From Tb to Ta, Inc_Incl showed a statistically significant change in the R, P, and S groups (p<0.05). Increase of clinical crown heights of the lower incisors (42, 4, and 31) was not statistically significant in any group. The only statistically significant intergroup difference was the greater increase of the clinical crown height of tooth number 32 in the P group in comparison with the R group (p=0.049). The change of lower incisor inclination during treatment did not lead to development of labial gingival recessions in the study sample

Amaçlar: Bu çalışmanın amacı, İç Anadolu bölgesinde yaşayan bireylerin, ortodontik tedavi ihtiyaçlarını ICON indeksi kullanarak değerlendirmek ve ortodontik tedavi ihtiyaçlarının cinsiyete ve pubertal büyüme dönemlerine göre değişip değişmediğini incelemektir. Yöntem: Mevcut çalışmada yaşları 9-38 arasında değişen 154 hastanın (87 kadın, 67 erkek) ortodontik modelleri ve panoramik filmleri ICON indeksi kullanılarak incelenmiştir. Bulgular: 154 hastanın 90’ında (% 58,4) ortodontik tedavi ihtiyacının olduğu, 87 bayan hastanın 49’unda (% 56,3) ve 67 erkek hastanın ise 41’inde (% 61,2) ortodontik tedavi ihtiyacının olduğu tespit edilmiştir. Ayrıca, prepubertal dönemde olan 37 hastanın 16’sında (% 43,2), pubertal dönemde olan 95 hastanın 62’sinde (% 65,3) ve postpubertal dönemde olan 22 hastanın ise 12’sinde (% 54,5) ortodontik tedavi ihtiyacının olduğu tespit edilmiştir. Estetik kaygılarından dolayı, bayanların ve pubertal dönem içindeki hastaların ortodontik tedavi için daha fazla başvuruya sahip oldukları görülmüştür. Sonuç: Sonuç olarak, cinsiyetlerin ve pubertal büyüme dönem gruplarının tedavi ihtiyaçları arasında önemli farklılık bulunmamıştır.Aims: The aim of the present study is to evaluate the treatment needs of persons lived in Middle Anatolian area using by ICON index. Additionally, it is aimed to examine orthodontic treatment needs according to gender and pubertal period. Methods: In current study, orthodontic models and panoramic films of 154 patients (87 women, 67 men) with the age range of 9-38 years were investigated using by ICON index. Results: 90 (58,4%) of 154 patients had orthodontic treatment need, 49 patients (56,3%) of 87 female patients and 41 patients (61,2%) of 67 male patients had orthodontic treatment need. In addition, the numbers of patients had orthodontic treatment need were; 16 (43,2%) of 37 patients in prepubertal period, 62 (65,3%) of 95 patients in pubertal period and 12 (54,5%) of 22 patients in postpubertal period. Due to the aesthetic anxieties, female and patients in pubertal period had more appeal for orthodontic treatment than the other groups. Conclusion: As a result, there was no significant difference in the treatment needs between the groups of gender and pubertal period

Comparison of arch forms between Turkish and North American

ABSTRACT Objective: The aim of this study was to clarify the morphological differences in the mandibular arches of Turkish and North American white subjects. Methods: The sample included 132 Turkish (34 Class I, 58 Class II, and 40 Class III) and 160 North American (60 Class I, 50 Class II, and 50 Class III) subjects. The most facial portion of 13 proximal contact areas was digitized from photocopied images of patients' mandibular dental arches. Clinical bracket points were calculated for each tooth based on mandibular tooth thickness data. Four linear and two proportional measurements were taken. The subjects were grouped according to arch form types (tapered, ovoid and square) in order to have frequency distribution compared between ethnic groups in each Angle classification. Results: The Turkish group showed significantly lower molar depth and more significant molar width-depth (W/D) ratio in all three Angle classifications. On the other hand, the Turkish group also showed a significantly larger intercanine width in Class III malocclusion and intermolar width in Class II malocclusion. The most frequent arch forms seen were the ovoid arch form in the Turkish group and the tapered form in the white group. Conclusions: Our results demonstrate that when treating Turkish patients, one should expect to use preformed ovoid arch form orthodontic wires in a significant percentage of patients

Evaluation of black spaces between maxillary central incisors by dentistry students and laypeople

WOS: 000411046800002PubMed: 28904309This study aimed to compare the perception of smile esthetics and alterations among dentistry degree students and laypeople to identify differences in the esthetic perception of black spaces between the maxillary central incisors among Turkish laypeople and students in different study years. Photographs altered to include black spaces of various sizes at the midline were evaluated by 208 dentistry students in years 1-5 and 45 Turkish laypeople. Perceptional differences in different photographs were statistically significant. The students in years 2-5 were more aware of differences between photographs than year 1 students and laypeople. The proportion of participants who decided the most attractive photograph as A was highest among 3rd year students, followed by 5th year students. However, the proportion of students agreeing on the least attractive image was highest among 4th year students, followed by 3rd year students. Photographs A and H were selected as the most and least attractive, respectively, by all participants. The esthetic perception of 1st and 2nd year dentistry students was very different from that of laypeople. To increase esthetic perception among dentistry students, specific lessons with clinical photography should be included in dental education
