Abstract

In orthodontics, it is important to assess the skeletal maturity in order to make accurate diagnosis and to plan for appropriate treatment. The objectives of this study were to identify (1) MP3 maturation stages, (2) CV maturation stages, and (3) agreement between MP3 and CV of 10-16 year-old orthodontic patients. Skeletal maturity of 72 subjects from the Orthodontic Clinic at the Dental Faculty of University of Indonesia was assessed by classifying developmental stages of MP3 as seen in a periapical film and CV as seen on a lateral cephalometric film. MP3 was classified into six stages according to Rajagopal and Kansal method. CV was also classified into six stages as described by Cervical Vertebrae Maturation Index (CVMI). The results showed that (1) at the same chronological age, MP3 and CV maturation stages could vary and the stages follow a gradual chronologic progression; (2) large variation of MP3 maturation stages was found in 12 year-old females (MP3-FG to MP3-I) and in 13-14 year-old males (MP3-FG to MP3-HI), (3) large variation of CV maturation stages was found in 12 year-old females (CVMI 2 to 5) and in 12-13 year-old males (CVMI 1, 2, 3 and 5), and (4) an agreement of 70.8% between MP3 and CV maturation stages was found in 10-16 year-old orthodontic patients. This study concluded that besides CVMI, the maturation stages of MP3 could be used as an alternative method to assess the skeletal maturity in orthodontics.DOI: 10.14693/jdi.v15i1.85

Abstract

In the mutilated case in adults, generally malocclusion is often accompanied by less support of periodontal tissues, such as alveolar bone resorption and gingival recession. The treatment of orthodontic is to arrange the teeth into good position and good occlusion, but is widely known to increase the alveolar bone resorption. In handling such case, orthodontist needs to look at factors which do not increase existing alveolar bone resorption and gingival recession. In this case report, it will be reported orthodontic treatment on mutilated case which are accompanied by alveolar bone resorption and gingival recession on a patient of 45 years and 4 months of age.

Abstract

Kasus gigitan silang depan sering dijumpai pada gigi teatap anak-anak pada periode geligi bercampur. Ada beberapa macam alat yang dapat dipergunakan untuk merawat kasus ini. Pada pasien anak-anak yang cukup kooperatif, salah satu alternatif adalah penggunaan alat lepasan dengan sekrup ekspansi. Alat ini terbuat dari basis akrilik yang terbagi dua di anterior dan posterior, diantaranya terdapat sekrup ekspansi. Pemakaian alat ini adalah dengan memutar sekrup 1/4 (seperempat)putaran, sehingga sisi basis di anterior akan mendorong atau memprotraksi gigi anterior yang mengalami gigitan silang ke arah labial. Laporan kasus ini menggambarkan penggunaan alat lepasan dengan sekrup ekspansi pada kasus gigitan silang dengan tipe dental.

Abstract

In orthodontic practice, orthodontist frequently face the patients with congenitally missing maxillary lateral incisors and mandibular second premolar. There are some treatment options for patients with congenitally missing second premolar such as keeping the deciduous second molar, extracting the molars and allowing space to close spontaneously, prosthetic replacement, autotransplantation and orthodontic space closure. Instead of treatment option for congenitally maxillary lateral incisor are orthodontic space opening for future restoration or orthodontic space closure using canines to replace missing maxillary lateral incisors. There are some factors must be consider before making a decision, such as the facial profile, dentoalveolar protrusion, the tooth size-arch length discrepancy, inclination and position of canine, dental esthetic of canines, occlusion, the dental relationship, patient’s age, the stage of development of the adjacent teeth and the condition of the deciduous predecessors with regard to root resorption and infracclusion. In this paper it will be discussed about the indications, advantages and disadvantages of both treatment modalities to help clinicians to cope with the malocclusion cases with congenital missing teeth. In this regard it needed teamwork among the orthodontist, prosthodontist, dental surgeon and restorative dentist to analyzing some factors related to individual patients and establishing overall treatment plans.DOI: 10.14693/jdi.v16i1.18

Abstract

Background: Several researches reported that Prostaglandin E2 (PGE2) injection on buccal mucosa combined with orthodontic pressure can faster tooth movement but has disadvantages such as high alveolar bone and root resorption furthermore pain from injection needle. PGE2 gel was made to better replace the lacks of injectable PGE2. Purpose: This research was aimed to prove that PGE 2 gel can penetrate rat’s oral mucosa effecting the appearance of PMN cells. Methods: This research was an in vivo laboratory experiment using 36 Sprague Dawley rats which were divided into 3 groups: normal group, topical PGE2 gel group after 1, 2, 4, 8 hours (4 subgroups), and topical gel without PGE2 group after 1, 2, 4, 8 hours (4 subgroups). Each group consists of 4 rats, therefore the total sample for all research groups were 36 rats. Gel with 25 µg/mL of PGE2 and gel without PGE2 were applied on oral mucosa for 2 minutes. Then, the rats were sacrificed after 1 hour, 2 hours, 4 hours, and 8 hours application. After that, the samples were prepared for histological examination with Hematoxyllin and Eosin. The picture were taken with OptiLab View and PMN cells amount were counted with light microscope, set 400 times of magnification. Results: Penetration effect of PGE2 gel on rat’s oral mucosa result in PMN inflammation cells distribution. One-way ANOVA showed no significant difference on PMN cells count in rats’ lower jaws between groups of normal and gel without PGE2. There was significant difference between groups of PGE2 gel and gel without PGE2 (p=0,001). PGE2 gel application showed PGE2 as inflammatory media, even though administered topically. Conclusion: PGE2 gel can penetrate rat’s oral mucosa, effecting PMN cells 1, 2, 4 and 8 hours after application of PGE2 gel.Latar belakang: Beberapa penelitian melaporkan bahwa injeksi (Prostaglandin E2) PGE2pada mukosa bukal yang dikombinasikan dengan tekanan ortodonti dapat mempercepat pergerakan gigi, tapi mempunyai kekurangan berupa resorpsi yang besar pada tulang alveolar dan akar gigi, serta adanya rasa sakit akibat penggunaan jarum suntik. Gel PGE2 dibuat untuk mengatasi kekurangan pemberian PGE2 secara injeksi. Tujuan: Untuk membuktikan bahwa gel PGE2 dapat berpenetrasi pada mukosa mulut tikus dengan efek munculnya sel PMN. Metode: Jenis penelitian adalah eksperimental laboratorik in vivo, menggunakan 36 tikus Sprague Dawley yang dibagi menjadi 3 kelompok, yaitu kelompok normal; kelompok pengolesan gel PGE2 setelah 1 jam, 2 jam, 4 jam, 8 jam (4 sub kelompok); kelompok pengolesan gel tanpa PGE2 setelah 1 jam, 2 jam, 4 jam, 8 jam (4 sub kelompok). Masing-masing kelompok terdiri 4 sampel, sehingga total sampel seluruh kelompok penelitian 36 tikus. Gel PGE2 dosis 25 µg/mL dan gel tanpa PGE2 dioleskan pada mukosa mulut rahang bawah selama 2 menit. Tikus di sacrifice setelah 1 jam, 2 jam, 4 jam dan 8 jam pengolesan. Kemudian dibuat sediaan histologi dengan pewarnaan Hematoxylin dan Eosin. Foto preparat diambil menggunakan OptiLab View. Hitung jumlah sel-sel PMN menggunakan mikroskop cahaya dengan pembesaran 400x. Hasil: Efek penetrasi gel PGE2 pada mukosa mulut terlihat distribusi sel-sel inflamasi PMN. Uji one-way ANOVA menunjukkan tidak ada perbedaan jumlah sel PMN yang bermakna pada mukosa rahang bawah tikus antara kelompok gel tanpa PGE2 dan normal. Ada perbedaan bermakna antara jumlah sel PMN kelompok pengolesan gel PGE2 dengan gel tanpa PGE2. (p = 0,001). Hasil aplikasi gel PGE2 menunjukkan gel PGE2 sebagai media inflamasi, meskipun zat aktif diberikan secara topikal. Kesimpulan: PGE2 gel dapat berpenetrasi ke mukosa mulut tikus, dengan efek adanya sel-sel PMN pada 1 jam, 2 jam, 4 jam dan 8 jam setelah pengolesan gel PGE2.

Abstract

Mistletoes are used traditionally in Indonesiaas medicinal plant, one of this as anticancer. Cancer isone of degenerative diseases could be triggered by toomuch free radicals in the body, whereas antioxidantcould reduced the risk of degenerative diseases.Mistletoes reposted content flavonoids which known have antioxidant activity. Mistletoe potency as drugmaterial should be studied sa the utilization ofmistletoe could be developed. Antioxidant activitytest using "DPPH free radical scavenger" methodand toxicity test using BSLT (Brine Shrimp LethalityTest) method had been conducted on water andethanol extracts of mistletoe Dendropthoe pentandra(L.) Miq.) that grown on various trees (star fruit,mango, cananga, duku, sour-sop, kepel, mahkotadewa, and tea). The result showed that ethanol andwater extracte-ofD, petandra on all host plants haveantioxidant activity (IC50 value between 6.4 - 51.8ug/mL). The result of toxicity test showed that ethanolextract of mistletoe on cananga, starfruit, kepel andmahkota dewa host plants have toxicity effect againstA. salina larvae with LCso value below 1000 ug/mL,nevertheless ethanol extract on others host plants andwater extract didn It give toxicity effect against A.salina larvae (LC50 > 1000 ug/mL).Key words: mistletoe, D. petandra, DPPH, antioxidant,toxicity, degenerative disea.
