“…4 The results of this study were different from those of Leung et al 8 on 12-year-old children in southern China that showed no significant differences between genders for the nasolabial and nasofrontal angle. According to the Graber and Singh method, previous research conducted by Hartanto and Lubis 11 on Chinese students at W.R. Supratman 1 and 2 high schools in Medan showed the students had straight facial profiles. There were no differences between genders.…”

Background: Soft tissue analysis is essential in treatment planning to ensure proportional, balanced, and harmonious soft tissue at the end of treatment. Several factors influence the variations, such as age and gender. Soft tissue profile analysis is usually studied from a lateral view. Purpose: The study aimed to determine whether there were differences in the average values of linear and angular measurement of the soft tissue profiles of the middle and lower third of the face between Chinese males and females high school students using lateral photometry. Methods: The samples were 100 lateral photographs (50 male and 50 female) of Chinese high school students at W.R. Supratman 1 and 2 in Medan. All samples were collected based on the inclusion and exclusion criteria obtained from secondary data. The linear and angular measurements were measured using Software Corel Draw 2019 and analysed statistically using an independent t-test and the Mann-Whitney test. Results: The inferior facial third, length of the lower lip, and prominence of the upper lip were, on average, greater in males, whereas in the prominence of pogonion, nasolabial angles, and nasofrontal angles were greater, on average, for females. Conclusion: There were significant gender differences in Chinese high school students in the inferior facial third, length of the lower lip, prominence of the upper lip, nasolabial angle, and nasofrontal angle, whereas there is no significant difference between genders in the prominence of the pogonion.

“…Perawatan ortodonti terkait erat dengan wajah seseorang karena mulut (terutama bagian jaringan lunak seperti bibir dan jaringan keras seperti gigi dan tulang rahang) merupakan salah satu faktor yang berperan membentuk karakteristik wajah seseorang. 1 Hasil estetika wajah yang seimbang serta oklusi fungsional yang baik didapatkan dengan penegakan diagnosis dan rencana perawatan yang tepat. Terdapat beberapa faktor fundamental yang perlu diperhatikan dalam menegakan diagnosis dan rencana perawatan yang tepat beberapa diantaranya adalah kondisi ruang, ukuran dan bentuk gigi serta rahang, gigi berjejal, jarak gigit serta diskrepansi lengkung gigi.…”

Pendahuluan: Diskrepansi ukuran gigi dan profil wajah merupakan dua faktor yang membantu dalam proses penegakan diagnosis dan penentuan rencana perawatan ortodonti. Pengukuran diskrepansi ukuran gigi dapat dilakukan dengan analisis Bolton, analisis ini dapat menunjukkan rasio lebar mesiodistal antara gigi pada maksila dan gigi pada mandibula. Profil wajah dapat digunakan sebagai guideline dalam menentukan estetik wajah yang ingin dicapai setelah perawatan. Tipe profil wajah dapat diinterpretasi dari hasil fotografi ekstraoral, pada penelitian ini analisis Bolton yang dilakukan hanya meliputi rasio anterior saja. Penelitian ini bertujuan untuk menganalisis hubungan antara diskrepansi ukuran gigi rahang atas dengan ukuran gigi rahang bawah berdasarkan analisis Bolton terhadap profil jaringan lunak wajah pada mahasiswa Fakultas Kedokteran Gigi Universitas Padjadjaran. Metode: Penelitian analitik observasional diawali dengan pengambilan sampel dengan teknik purposive sampling dan didapatkan 50 orang sampel mahasiswa Fakultas Kedokteran Gigi angkatan 2016 kemudian dilakukan analisis rasio anterior Bolton pada model studi dan interpretasi hasil foto profil ekstraoral. Uji korelasi Pearson dilakukan untuk mengetahui korelasi dari kedua variabel tersebut. Hasil: Rata-rata anterior ratio dari 50 orang sampel sebesar 79,53% ±2,61 dengan profil wajah lurus sebanyak 33 orang (66%) dan profil wajah cembung sebanyak 17 orang (34%) dengan rata-rata derajat konveksitas 172,11°. Uji korelasi Pearson menghasilkan nilai p-value (0,896) yang lebih besar dari α=0,05. Tidak ada korelasi yang signifikan antara diskrepansi ukuran gigi dan profil wajah. Simpulan: Tidak terdapat hubungan antara diskrepansi ukuran gigi dan profil wajah.Kata kunci: Analisis Bolton, diskrepansi ukuran gigi, profil wajah. ABSTRACTIntroduction: Tooth size discrepancy and facial profile are two crucial factors for helping diagnosis and treatment planning of orthodontic treatment. Bolton analysis could measure tooth size discrepancy; and the analysis result shows the ratio of mesiodistal width between maxillary and mandibular teeth. The facial profile could be used as a guideline for aesthetic result in orthodontic treatment. The facial profile can be analysed from an extraoral profile photograph. In this research, we only calculate the anterior ratio of the sample. The purpose of this study was to determine the correlation between maxillary and mandibular anterior size discrepancy and soft tissue facial profile of the students of the Faculty of Dentistry Universitas Padjadjaran based on Bolton analysis. Methods: The research was conducted with observational analytic methods. The sampling method was conducted using the purposive sampling method, which resulted in 50 samples taken from students of the Faculty of Dentistry Universitas Padjadjaran batch 2016. Analysis of the sample’s anterior ratio was measured on the study cast with Bolton analysis and interpretation of the extraoral profile photograph. Both variables (tooth size discrepancy and facial profile type) were then analysed with Pearson’s correlation test to determine the correlation between the two variables. Results: The average anterior ratio from 50 samples was 79.53% ± 2.61, and the most common facial profile type was straight/orthognathic, which was found in 33 samples (66%) followed by convex in 17 samples (34%) with average facial convexity was 172.11°. The result of Pearson’s correlation test showed that the p-value was 0.896, which was higher than α = 0.05. There was no significant correlation between tooth size discrepancy and soft tissue facial profile. Conclusion: There is no correlation between tooth size discrepancy and soft tissue facial profile.Keywords: Bolton analysis, tooth size discrepancy, facial profile.

Background: Tooth size discrepancy is defined as an imbalance in size between each tooth. To obtain good occlusion with overbite and overjet, the maxillary and mandibular teeth must be of the appropriate size. One of the causes of malocclusion is the mismatch of the mesiodistal size of the teeth to the arch of the jaw. The relation of teeth with a large maxillary mesiodistal size while the mandibular mesiodistal size is small, it is impossible to get an ideal occlusion. This condition is known as tooth size discrepancy and can be a problem when determining the orthodontic treatment plan and when achieving the final orthodontic treatment outcome. Purpose: this study aimed to describe Bolton's analysis in cases of Class I, II, and III malocclusions. Review(s): The literature sources used in preparing the review were through databases PubMed and Google Scholar with the keywords tooth size discrepancy, Bolton analysis, and Class I, II, and III malocclusions. From the results of the researchers' measurements on malocclusions in the Angle Classification Class I and II, The anterior ratio was different in several cases, while in Class III the results were greater than the Bolton ratio, where the size of the lower jaw teeth was larger than the maxillary teeth, especially in the anterior ratio. Conclusion: Bolton's analysis can be applied to all cases regardless of the type of malocclusion, gender, or race, and remains an important investigation before starting treatment for post-treatment arch stability.
