ABSTRACT Objectives: To investigate the retromolar space available for molar distalization in patients with mandibular prognathism. Materials and Methods: Using cone-beam computed tomography, the posterior mandibular dimensions in 110 consecutive patients with Class I or Class III malocclusion were measured (mean age, 27.0 ± 7.1 years). The shortest linear distances from the distal root of the right mandibular second molar to the inner border of the mandibular cortex were measured at the level of root furcation and 2, 4, and 6 mm apical to the furcation along the sagittal line and the posterior line of occlusion. The retromolar distances were compared between the Class I and Class III malocclusion groups using general linear mixed models. Results: The retromolar space measured through the sagittal line showed no significant intergroup difference. Among the distances measured through the posterior line of occlusion, the space measured at depths 0 and 2 mm to the furcation were significantly greater in the Class III group than in the Class I group. Conclusions: Patients with Class III malocclusion have greater retromolar space for mandibular molar distalization along the posterior line of occlusion only at the level of the second molar furcation.

Abstract: The first molars of mandibulae are the first permanent teeth which erupt around 6-7 years old; therefore, they have the highest risk of dental caries. When the dental caries occurs in a tooth, it can lead to tooth extraction which results in new problems such as changing of teeth position, influence on occlusion, jaw joints, and mastication process. This study aimed to describe the extraction profile of the first mandibular molar based on age and gender at Balai Pengobatan Rumah Sakit Gigi dan Mulut Manado in 2012. This was a descriptive retrospective study. Samples were obtained by using total sampling method. In 2012, there were 765 patients with extracted teeth. Of the 1130 permanent teeth extracted, the highest number belonged to the first mandibular molar which was 167 teeth out of 164 patients. Extraction of the first mandibular molars among adults (19-55 years old) was 73%; teenagers (13-18 years old) 21%; children (6-12 years old) 4%; and elderies (>56 years) %. Of the 164 patients, there were 99 females and 65 males. Conclusion: Adults were the most frequent age group with extracted first mandibular molar, followed by teenagers, children, and elderly. Female cases were more frequent than male cases.Keywords: tooth extraction, mandibular first molarAbstrak: Gigi molar satu mandibula merupakan gigi tetap yang pertama erupsi pada umur sekitar 6-7 tahun, sehingga menjadi gigi yang paling berisiko terkena karies. Bila gigi tersebut terkena karies, dapat berakibat pencabutan, yang menimbulkan resiko baru seperti perubahan posisi gigi, memengaruhi oklusi, sendi rahang, dan proses mastikasi yang berdampak pada penyerapan nutrisi makanan. Penelitian ini bertujuan untuk mengetahui gambaran pencabutan gigi molar satu mandibula di Balai Pengobatan Rumah Sakit Gigi dan Mulut Manado berdasarkan umur dan jenis kelamin tahun 2012. Penelitian ini bersifat deskriptif dengan jenis penelitian retrospektif. Pengambilan sampel menggunakan teknik total sampling. Hasil penelitian menunjukkan bahwa pada tahun 2012 dari 765 pasien yang melakukan pencabutan gigi, sebanyak 1130 gigi dewasa yang dicabut dan gigi molar satu mandibula yang tersering (167 gigi pada 164 pasien). Kasus pencabutan gigi molar satu mandibula pada kelompok usia dewasa dengan rentang umur 19-55 tahun sebesar 73%; pasien remaja (13-18 tahun) 21%; pasien anak-anak (6-12 tahun) 4%; dan pasien lansia dengan rentang umur mulai dari 56 tahun ke atas 2%. Dari 164 pasien yang dilakukan pencabutan gigi molar satu mandibula, jenis kelamin perempuan sebanyak 99 pasien sedangkan laki-laki 65 pasien. Simpulan: Pasien dewasa merupakan kategori umur yang tersering dilakukan pencabutan gigi molar satu mandibula, diikuti oleh pasien remaja, anak, dan lansia. Kasus pencabutan gigi molar satu mandibula berdasarkan jenis kelamin lebih sering terjadi pada perempuan dibandingkan laki-laki.Kata kunci: pencabutan gigi, molar satu mandibula
