Background: Molar band as anchoring device may be contaminated during the fitting process. Thus, decontamination process is essential to prevent cross-infection between patients. Purpose: The objective of this research was to determine the amount of bacteria in molar band post-fitted on the patient teeth, after previously undergone pre-sterilization using alcohol and ultrasonic cleaning bath followed by sterilization using dry heat oven and steam autoclave, in order to find the best method in decontamination of post-fitted molar band. Methods: Four molar bands which already fitted on one patient then divided evenly into two groups. The first group was pre-sterilized using alcohol. One of the bands then sterilized using dry heat oven, while the other one was sterilized using steam autoclave. The second group was pre-sterilized using ultrasonic cleaning bath. One band from this group then sterilized using dry heat oven and the other was sterilized using steam autoclave. The next step was to immerse all the bands in a phosphate-buffered saline solution. Using micropipette, the solution was retrieved and dropped upon a petri dish containing Brain Heart Infusion broth. The dish was then stored in an incubator for 24 hours, prior to counting the number of bacteria existed. The same methods were used to the rest of the patients, with total 128 molar bands from 32 patients. Results: There was a profound difference in numbers of bacteria found between those methods of sterilization. However, there was a non significant difference between the two groups which were at the alcohol-steam autoclave group and at the ultrasonic cleaning bath-steam autoclave group. Conclusion: This study showed that steam autoclave is better than for sterilizing molar band, as it left the minimal amount of bacteria in post-fitted molar band.Latar belakang: Molar band merupakan suatu alat penjangkaran yang dapat mengalami kontaminasi selama proses fitting band, sehingga perlu dilakukan suatu proses dekontaminasi untuk menghindari terjadinya cross-infection pada pasien. Tujuan: Penelitian ini bertujuan untuk mengetahui perbedaan jumlah bakteri pada molar band pasca fitting band setelah sterilisasi dry heat oven dan steam autoclave yang sebelumnya telah dilakukan pre-sterilisasi alcohol dan ultrasonic cleaning bath, sehingga dapat ditentukan metode sterilisasi yang terbaik dalam dekontaminasi molar band. Metode: Empat molar band yang telah melalui proses fitting band pada seorang pasien dibagi dalam dua kelompok. Pada kelompok pertama, dua molar band dilakukan pre-sterilisasi dengan alkohol, kemudian satu band dilakukan sterilisasi dengan dry heat oven dan satu band lainnya dengan steam autoclave. Kelompok kedua, dua molar band dilakukan pre-sterilisasi dengan ultrasonic cleaning bath, kemudian satu band dilakukan sterilisasi dengan dry heat oven dan satu band lainnya dengan steam autoclave. Molar band tersebut masing-masing kemudian dimasukkan ke dalam cairan phosphate-buffered saline, dengan micropipette cairan diambil dan dituangkan ke cawan petri yang berisi Brain Heart Infusion. Kemudian dimasukkan ke dalam inkubator selama 24 jam dan dihitung jumlah bakterinya. Metode yang sama dilakukan terhadap molar band lainnya, dengan total 128 molar band dari 32 pasien. Hasil: Terdapat perbedaan jumlah bakteri yang bermakna antara beberapa kelompok metode sterilisasi dan terdapat satu kelompok dengan perbedaan tidak bermakna, yaitu kelompok alcohol-steam autoclave dengan ultrasonic cleaning bath-steam autoclave. Simpulan: Hasil penelitian menunjukkan bahwa steam autoclave merupakan metode sterilisasi yang terbaik pada molar band yang telah melalui proses fitting band karena menunjukkan jumlah bakteri yang paling minimal.

Background: A complete unilateral cleft lip and palate generally results in asymmetry of the midface. The lack of continuity in the perilabial musculature through the midline contributes to a malpositioning of the underlying osseus structures which are often underdeveloped. Purpose: The purpose of this study was to determine whether there are differences in the craniofacial morphology among children with complete unilateral cleft lip and palate following labioplasty and palatoplasty as compared with children without cleft lip and palate at the same pubertal age. Methods: A series of 14 consecutively treated subjects with complete unilateral cleft lip and palate following labioplasty and palatoplasty were compared with 14 pubertal stage-matched controls with normal craniofacial structure. Pubertal stage was determined with cervical vertebral maturation (CVM) method improved by Baccetti et al, 2002. Lateral cephalograms were used for comparison. An unpaired t-test was run for 14 subjects with complete unilateral cleft lip and palate and 14 normal subjects. Results: There were significant cephalometric differences in anterior cranial base length (p = .002), cranial base length (p = .001), maxillary length (p = .000), mandibular length (p = .000), mandibular ramus height (p = .000), mandibular body length (p = .002), and upper anterior face height (p = .004). There was no significant cephalometric difference in posterior cranial base length (p = .051), lower anterior face height (p = .206), posterior face height (p = .865), growth pattern/ facial type (p = .202). Conclusion: There were craniofacial morphology differences between children with complete unilateral cleft lip and palate post labioplasty and palatoplasty and children without cleft lip and palate at the age of pubertal. Children with complete unilateral cleft lip and palate post labioplasty and palatoplasty had shorter length of the anterior cranial base, cranial base, maxilla, mandible, mandibular ramus height, mandibular body, and upper anterior face height as compared with children without cleft lip and palate at the age of pubertal.Latar belakang: Celah bibir dan langit-langit unilateral komplit umumnya menghasilkan asimetri wajah bagian tengah. Berkurangnya kontinuitas otot di sekitar bibir yang melewati garis tengah wajah mengakibatkan malposisi struktur tulang di bawahnya yang seringkali kurang berkembang. Tujuan: Tujuan penelitian ini adalah untuk menentukan apakah terdapat perbedaan morfologi kraniofasial anak dengan celah bibir dan langit-langit unilateral komplit pasca labioplasti dan palatoplasti dibandingkan anak tanpa celah bibir dan langit-langit pada usia pubertal. Metode Penelitian: Sejumlah subyek penelitian berupa 14 orang anak penderita celah bibir dan langit-langit pasca labioplasti dan palatoplasti dibandingkan dengan 14 orang anak yang normal pada masa pubertal yang sama. Masa pubertal ditentukan menggunakan metode cervical vertebral maturation (CVM) yang dikembangkan oleh Baccetti dkk, 2002. Dilakukan perbandingan hasil pengukuran sefalogram lateral dari kedua kelompok. Uji-t tidak berpasangan dilakukan untuk mengetahui perbedaan gambaran kraniofasial antara kelompok anak dengan celah bibir dan langit-langit unilateral komplit pasca labioplasti dan palatoplasti dan kelompok anak normal. Hasil: Terdapat perbedaan bermakna pada panjang basis kranium anterior (p = .002), panjang keseluruhan basis kranium (p = .001), panjang maksila (p = .000), panjang mandibula (p = .000), tinggi ramus mandibula (p = .000), panjang badan mandibula (p = .002), tinggi wajah anterior atas (p = .004). Tidak terdapat perbedaan bermakna pada panjang basis kranium posterior (p = .051), tinggi wajah anterior bawah (p = .206), tinggi wajah posterior (p = .865), pola pertumbuhan/tipe wajah (p = .202). Kesimpulan: Terdapat perbedaan morfologi kraniofasial antara anak dengan celah bibir dan langit-langit unilateral komplit pasca labioplasti dan palatoplasti dibandingkan anak tanpa celah bibir dan langit-langit pada masa pubertal. Anak dengan celah bibir dan langit-langit unilateral komplit pasca labioplasti dan palatoplasti memiliki panjang basis kranium anterior, panjang keseluruhan basis kranium, panjang maksila, panjang mandibula, tinggi ramus mandibula, panjang badan mandibula, dan tinggi wajah anterior atas yang lebih pendek dibandingkan anak tanpa celah bibir dan langit-langit pada masa pubertal.

Background: Enamel demineralization is a common and undesirable side effect of fixed appliance orthodontic treatment. Many sudies showed that the prevalence varied between 2–96%. There are many ways to prevent demineralization and increased remineralization such as oral hygiene instruction and by topical application such as acidulated phosphate fluor (APF) casein phospo peptide-amorphous calcium phosphate (CPP-ACP), casein phospo peptide-amorphous calcium phosphate plus (CPP-ACPF). Purpose: The purpose of this in-vitro study was to evaluate the efficacy of various topical agents to prevent enamel demineralization. Methods: Fourty extracted human premolars were allocated to 1 of 4 groups: 1.23% APF gel; 10% CPP-ACP paste; 10% CPP-ACPF paste; and untreated control. All samples were subjected to pH cycling treatment for 12 days through a daily procedure of demineralization solution with pH 4 for 6 hours and remineralization solution with pH 7 for 18 hours. Microhardness testing were done before and after pH cycling and the delta hardness values were determined. Results: APF, CPP-ACP and CPP-ACPF application significantly prevent lowering of enamel microhardness value compared with untreated control group. Kruskal-Wallis, ANOVA, Mann-Whitney U, Tukey and Bonferroni Post-Hoc multiple comparison test showed significant difference between mean delta microhardness value of CPP-ACPF and CPP-ACP group with APF group, but there is no significant difference between mean delta microhardness value of CPP-ACPF and CPP-ACP group. Conclusion: APF, CPP-ACP and CPP-ACPF prevent enamel demineralization. CPP-ACP and CPP-ACPF prevent demineralization more than APF.Latar belakang: Demineralisasi email merupakan efek samping negatif yang sering dijumpai pada perawatan ortodontik cekat. Beberapa penelitian menyatakan bahwa prevalensinya bervariasi 2–96 persen. Ada beberapa cara untuk mencegah demineralisasi dan meningkatkan remineralisasi, misalnya dengan instruksi kebersihan mulut dan menggunakan bahan topical aplikasi seperti acidulated phosphate fluor (APF) casein phospo peptide-amorphous calcium phosphate (CPP-ACP), casein phospo peptide-amorphous calcium phosphate plus (CPP-ACPF). Tujuan: Tujuan penelitian in vitro ini adalah untuk mengevaluasi efektivitas berbagai agen topikal untuk mencegah demineralisi email yang dilihat dengan uji kekerasan mikro permukaan email. Metode: emapat puluh gigi premolar yang sudah di ekstraksi dibagi dalam 4 kelompok: aplikasi gel 1,23% APF; aplikasi psta 10% CPP-ACP; aplikasi pasta 10% CPP-ACPF dan kelompok Kontrol. Semua sampel diberikan perlakuan siklus pH selama 12 hari yang terdiri dari perendaman dalam larutan demineralisasi dengan pH 4 selama 6 jan dilanjutkan dengan perendaman dalam larutan remineralisasi dengan pH 7 selama 18 jam. Uji kekerasan dilaku kan sebelum dan sesudah perlakuan serta diperoleh juga data delta kekerasan. Hasil: Semua aplikasi agen topikal tersebut dapat mencegah demineralisasi email secara signifikan dibandingkan kelompok kontrol. Kesimpulan: APF, CPP, ACP, dan CPD-ACPF mencegah demineralisasi enamel. CPP-ACP dan CPD-ACPF mencegah demineralisasi lebih baik dibanding APF.

ABSTRAKPendahuluan: Impaksi gigi premolar kedua bawah sering dijumpai, prevalensi di peringkat ketiga setelah gigi molar ketiga dan kaninus atas. Beberapa cara penatalaksanaan gigi impaksi dapat dilakukan. Pemilihan rencana perawatan tergantung pada posisi, jarak dengan bidang oklusal, tahap perkembangan, dan hubungan gigi impaksi dengan gigi-gigi di dekatnya, kebutuhan perawatan ortodonti, usia pasien, serta respons penyembuhan jaringan keras dan lunak setelah tindakan bedah. Pasien dirawat tanpa tindakan exposure bedah, dilakukan pencabutan gigi 34 yang menghalangi jalur erupsi gigi 35, dilanjutkan perawatan ortodonti cekat guna membuka ruang bagi gigi 35 dan menarik gigi 35 masuk ke dalam bidang oklusal. Tujuan laporan kasus menyampaikan penatalaksanaan perawatan ortodonti impaksi gigi premolar kedua bawah kiri tanpa exposure bedah. Laporan kasus: Pasien wanita usia 20 tahun dengan maloklusi skeletal kelas II divisi 1 disertai bimaksilaris dentoalveolar protrusion, tipe wajah brachyfacial, profil cembung dan terdapat impaksi gigi 35. Pemasangan breket MBT slot 0,22” dilakukan setelah gigi 14, 24 dan 34 dicabut. Ruangan untuk erupsi gigi 35 dijaga dengan memasang open coil spring di antara gigi 33 dan 36. Setelah terdapat ruang yang cukup bagi gigi 35, dilakukan penarikan gigi 35 ke dalam lengkung gigi. Total waktu perawatan adalah 21 bulan. Gigi 35 yang impaksi sudah masuk ke dalam bidang oklusal, profil jaringan lunak pasien membaik, bibir atas menjadi lebih kompeten dan tercipta lip seal karena overjet berkurang. Simpulan: Penatalaksanaan pasien perawatan gigi impaksi premolar kedua bawah tanpa exposure bedah efektif dan senyum pasien lebih estetik dengan posisi gigi anterior terhadap profil yang terkoreksi dengan baik.Kata kunci: gigi impaksi; gigi premolar; exposure bedah ABSTRACTIntroduction: Impacted lower second premolars are typical cases in the third rank after third molars and upper canines. There are several ways to treat impacted teeth. The choice of treatment plan depends on the position, distance to the occlusal plane, developmental stage, relationship of the impacted tooth to adjacent teeth, orthodontic treatment needs, patient age, and the healing response of hard and soft tissues after surgery. The patient was treated without surgical exposure. Tooth 34 was extracted, which blocked the eruption path of tooth 35, followed by fixed orthodontic treatment to open space for tooth 35 and pull tooth 35 into the occlusal plane. This case report aims to present the management of impacted orthodontic treatment of the left lower second premolar without surgical exposure. Case report: A 20-year-old female patient with skeletal class II division 1 malocclusion, bimaxillary dentoalveolar protrusion, brachyfacial facial type, convex profile, and impacted tooth 35. MBT bracket insertion of 0.22" slot was performed after teeth 14, 24 and 34 were extracted. The space for the eruption of tooth 35 was maintained by placing an open coil spring between teeth 33 and 36. Once there was sufficient space for tooth 35, tooth 35 was pulled into the dental arch. The total treatment time was 21 months. The impacted tooth 35 had entered the occlusal plane, the patient's soft tissue profile improved, the upper lip became more competent, and a lip seal was created due to reduced overjet. Conclusion: Management of patients with impacted lower second premolars without adequate surgical exposure and the patient's smile is more aesthetically pleasing with the position of the anterior teeth in a well-corrected profile.Keywords: impacted tooth; premolars; surgical exposure

Gigitan silang anterior dapat dibedakan menjadi gigitan silang skeletal dan dental. Kasus maloklusi gigitan terbuka anterior yang disebabkan oleh faktor skeletal berhubungan dengan pola pertumbuhan mandibula ke bawah dan ke belakang. Pola skeletal vertikal hiperdivergen pada pasien gigitan terbuka anterior menuntut operator untuk menjaga dimensi vertikal agar tidak memperparah kondisi yang ada. Penggunaan peranti cekat sistem ligasi pasif memberikan keuntungan pada perawatan pasien dengan maloklusi kelas III dan gigitan terbuka anterior. Pasien perempuan berusia 17 tahun datang ke Klinik Ortodonti RSKGM FKG UI dengan keluhan lidah sering tergigit sewaktu tidur dan menyebabkan sariawan. Pasien memiliki wajah dolikofasial, simetris, dan tidak seimbang. Hasil analisismenunjukkan bahwa pasien memiliki pola skeletal kelas III dengan maksila dan mandibula retrognati terhadap basis kranii (SNA 77°, SNA 76°, ANB 1°) dengan pola vertikal wajah hiperdivergen yang disertai gigitan terbuka anterior. Pasien dirawat menggunakan peranti cekat passive self ligating. Perawatan ortodonti selesai dalam waktu 15 bulan dan keluhan utama, crowding, serta gigitan terbuka pada regio anterior telah terkoreksi. Perawatan gigitan terbuka anterior dengan kombinasi ekstrusi anterior dan intrusi posterior baik dilakukan pada pasien dengan pola skeletal vertikal hiperdivergen.

Introduction: Based on Indonesia Basic Health Research in 2018, it is known that 47% of Lampung people experience tooth decay and only 51% of them regularly go to the dentist. The need for orthodontic treatment is quite high among students. Epidemiological studies in Japan show that around 40% of teenagers aged 15-18 years need orthodontic treatment, 27%-36% in England aged 10-15 years, while in South Jakarta (2004) is 48.5%. Brook and Shaw introduced the Index of Orthodontic Treatment Need (IOTN), to assess the need for orthodontic treatment in England. IOTN has been applied by Agusni, T to measure the treatment needs of urban and rural children in Surabaya. Objective: Aims to determine the perceptions of elementary school students in Lampung regarding Malocclusion and the need for Orthodontic treatment. Method: A cross-sectional study was conducted in May 2023, carried out on students at public Elementary School Bumi Agung who met the inclusion criteria, namely aged 9-13 years, had never and were not currently undergoing orthodontic treatment, and were willing to take part in the research. 130 people were selected using a purposive sampling technique. Questionnaires were used to obtain sociodemographic data and general knowledge about Dental and Oral Health and Malocclusion. Assessment of the need for orthodontic treatment was carried out using the AC IOTN by the subject and operator. Results: 90% of students answered the questionnaire correctly, and 42% of students needed orthodontic treatment. A Pearson Chi-Square analysis test was carried out and found that there was a statistical difference in the perception of the need for orthodontic treatment by students and operators (p-value <0.05). Conclusion: Students at SDN Bumi Agung, Kalianda, Lampung, have very good general knowledge about Dental and Oral Health and Malocclusion. However, this is unsubstantiated by the perception of the need for orthodontic treatment.

Class II malocclusion exhibits a significant correlation with diverse vertical skeletal patterns. Various vertical analyses have been widely used to see the height of face, but their reference points produce different interpretations. Therefore, it is necessary to use more than one vertical parameter as a reference in establishing orthodontic diagnosis and treatment plans. In addition, facial proportions can also be used to assess vertical components. Moving on from this, it will be known whether there is a correlation of vertical parameters with facial proportions in cases of class II malocclusion in non-growing individuals ages > 19 years. Discover the correlation between vertical parameters and facial proportions in skeletal class II malocclusion. A total of 65 cephalometric class II malocclusions that met the inclusion and exclusion criteria were obtained from the Orthodontic Clinic of Faculty of Dentistry, Universitas Indonesia. The cephalogram was measured to determine the angles of A point to B point (ANB), maxillary mandibular plane angle (MMPA), lower anterior facial height (LAFH) and facial axis. The correlation between MMPA and LAFH was analyzed using the Spearman correlation test, while the facial axis and LAFH were analyzed using the Pearson correlation test. Average class II malocclusion patients have a mean ANB value of 7.03º with an MMPA angle of 30.78º. The average portion of LAFH is 55.05% with a facial axis of 84.11º. The findings of this study indicate that there is a correlation between MMPA and LAFH, but there is no correlation between facial axis and LAFH. This study indicates that greater MMPA angle values of class II malocclusion in non-growing patients ages > 19 years will result in a high lower proportion, and vice versa.
