Abstract

Background: The masticatory system as a biologic system is subjected to harmful influences of varying severity. Almost half of routine patients requesting prosthodontic treatment indicated at least one sign or symptom of temporomandibular disorders. Analysis of the masticatory system often neglected by dentist. Untreated temporomandibular disorders may significantly implicated in the perpetuation of the disorder and may interfere with routine prosthodontic clinical procedures. It would be resulted unsuccessful long term goal of prosthodontic rehabilitation because of the uncompleted diagnoses and treatment plan. Purpose: The purpose of this case report was to give the information of the importance of masticatory functional analysis in the diagnostic finding for treatment planning in the prosthodontic rehabilitation. Case: A 45 year - old male patient, partial dentate with reduced chewing efficiency, mild pain in right preauricular region in function, left click in opening mouth, severe attrition on all anterior lower teeth with vertical dimension of occlusion decreased due to loss of posterior support. He wanted to make a new denture. Case management: Record and analyze of active and passive mandibular movement, opening pathway, muscle and temporomandibular joints palpation, load testing, and vertical dimension of occlusion with manual functional analysis (MFA), occlusal condition and radiographic examination. Treatment plan was formulated into 3 phases: stabilization of the masticatory system, definitive treatment and periodical control. The result of this treatment excellent for 1 year evaluation after permanent cementation. Conclusion: Masticatory functional analysis is very important and must be done in the diagnosis finding for treatment planning in every case of prosthodontic rehabilitation.Latar belakang: Sistem pengunyahan sebagai sistem biologis sewaktu-waktu dapat terjadi gangguan dengan berbagai derajat keparahan. Hampir setengah dari jumlah pasien yang memerlukan perawatan prostodontik minimal menunjukkan satu tanda atau keluhan dari gangguan temporomandibular. Analisis fungsional sistem pengunyahan masih sering dilupakan oleh dokter gigi. Gangguan temporomandibular yang tidak dirawat akan terus ada dan mungkin dapat mengganggu prosedur klinis perawatan prostodonsia. Hal tersebut akan menyebabkan keberhasilan klinis jangka panjang perawatan prostodonsia tidak dapat tercapai karena diagnosis dan rencana perawatan yang kurang lengkap. Tujuan: Tujuan dari laporan kasus ini adalah untuk memberikan informasi tentang pentingnya analisis fungsional sistem pengunyahan untuk menegakkan diagnosis dan rencana perawatan pada perawatan prostodonsia. Kasus: Pasien laki-laki usia 45 tahun, bergigi sebagian merasa sulit untuk mengunyah makanan, nyeri ringan di daerah depan telinga kanan saat fungsi, keletuk sendi kiri saat membuka mulut, atrisi pada seluruh gigi depan rahang bawah disertai penurunan dimensi vertikal oklusi akibat kehilangan dukungan gigi belakang. Dia ingin membuat gigi tiruan yang baru. Tatalaksana kasus: Mencatat dan menganalisis pergerakan aktif dan pasif rahang bawah, arah pergerakan rahang bawah saat membuka mulut, palpasi otot-otot pengunyahan dan sendi temporomandibula, uji beban, dimensi vertikal oklusi dengan metode analisis fungsional secara manual, keadaan oklusal dan radiologis. Rencana perawatan dibagi menjadi 3 tahap berupa stabilisasi sistem pengunyahan, perawatan tetap dan kontrol secara periodik. Hasil perawatan menunjukkan keberhasilan klinis yang baik setelah dilakukan evaluasi selama 1 tahun setelah penyemenan tetap. Kesimpulan: Analisis fungsional sistem pengunyahan sangat penting dan harus dilakukan untuk menegakkan diagnosis dan rencana perawatan pada setiap perawatan prostodonsia.

Abstract

Background: Patient suffering from occlusal abnormality is usually detected months or even years when the acute patient visits a dentist, and generally the patient does not receive direct treatment upon his complaints since minimum information is available on this type of treatment. In general, the dentist provides medication only or conducts incorrect selective grinding where in fact, the patient does not feel better from the previous conditions. Purpose: The objective of this study is to discuss the treatment on the dysfunctional temporomandibular joint followed by orofacial pain caused by occlusal disorder using occlusal splint. Case: In this case, a forty three years old male having trouble with the joint on the left jaw followed by orofacial pain caused by occlusal disorder. Case Management: Initial treatment with occlusal splint makes the patient comfortable and recovers from his complaints since the patient could restructure the chewing muscles. This treatment will be more successful if the dentist has the knowledge to use and choose occlusal splint method properly. Occlusal Splint could be used as a supporting therapy and consideration as one of the therapies to avoid the unwanted side effects. The use of occlusal splint is meant as an alternative of the main therapy in overcoming the problem of occlusal splint. Conclusion: Finally, therapy with occlusal splint is very effective as an alternative treatment to handle the dysfunction of temporomandibular joint caused by occlusion.

Abstract

Background: Preservation of sockets is a procedure aimed to reduce bone resorption after tooth extraction. One of the most commonly used xenograft materials is demineralized freeze-dried bone bovine xenograft (DFDBBX). Meanwhile, one of the key regulations in osteoclast genesis process is RANKL bond. A decrease in the number of RANKL expressions can suppress the osteoclast genesis process so that bone resorption can be prevented. The combination of Moringa leaf extract and DFDBBX, as a result, is expected to decrease the number of RANKL. Purpose: This study aimed to measure RANKL expressions in tooth extraction socket treated with Moringa leaf extract combined with DFDBBX. Methods: Fifty six Cavia cobaya rats were divided into eight groups. The first group was a control group with PEG administration onto their extraction sockets. The second group was a treatment group with DFDBBX administration. The third group was a treatment group with Moringa leaf extract administration. The fourth group was a treatment group induced with a combination of DFDBBX and Moringa leaf extract. Examination then was performed on days 7 and 30. After 7 and 30 days, those Cavia cobaya rats were executed and tested with immunohistochemical techniques. Further research data collected then were tested with one-way ANOVA. Results: There were significant differences between the control group and the groups induced with the combination of Moringa leaf extract and DFDBBX. On days 7 and 30, the groups induced with the combination of Moringa leaf extract and DFDBBX had the lowest number of RANKL expressions. Conclusion: The combination of Moringa leaf extract and DFDBBX can decrease the number of RANKL expressions in Cavia cobaya rats on the day 7 and day 30 after tooth extraction.

Abstract

Background: After tooth extraction, the socket leaves a defect on the alveolar bone. The administration of shell crab-derived hydroxyapatite maintains bone dimensions that are important for achieving successful prosthodontic treatment. Purpose: The aim of the study was to determine the osteogenic properties, such as the number of osteoclasts, osteoblasts and osteocytes, after the application of hydroxyapatite-based shell crab in the post-extraction sockets of Wistar rats. Methods: There were two groups: the control group (K) and the treatment group (T). Wistar rats were randomly divided into control and treatment groups. After tooth extraction, hydroxyapatite gel derived from Portunus pelagicus shells was applied to the tooth sockets of Wistar rats. Observations and calculations of osteoclasts, osteoblasts and osteocytes were carried out on the 14th and 28th days under a light microscope with 400 times magnification. Statistical analysis was performed using one-way ANOVA. Results: There was a significant difference (p<0.05) between the K14 and P14 groups, K28 and P28 groups, K14 and K28 groups, and P14 and P28 groups. The results indicated that there were significant differences between groups of variables. Conclusion: The application of shell crab-derived hydroxyapatite (Portunus pelagicus) was able to decrease the number of osteoclasts and increase the number of osteoblasts and osteocytes.

Abstract

Background: Socket preservation using bone graft is one way to minimise resorption and maximise the bone formation process. Tumor necrosis factor-α (TNF-α) is an inflammatory cytokine that affects bone regenerating osteoblast activity, while osterix (Osx) is an osteoblast-specific transcription factor that activates gene receptors during pre-osteoblast differentiation. The hydroxyapatite (HA) scaffold from crab shells (Portunus pelagicus) has osteoconduction properties. Purpose: To analyse the decrease of TNF-α expression and the increase of Osx expression and the correlation between these two in the post-extraction socket after the transplantation of a crab shell HA scaffold. Methods: The lower left incisors of Cavia cobaya (n = 24) were extracted and divided into four groups: the first and second groups were control groups on Day 7 and Day 14 (K7 and K14), the third and fourth groups were treatment groups (P7 and P14). The statistical analysis used was a multivariate analysis of variance (MANOVA) with a significance level of 0.05. Results: A MANOVA test showed that the use of crab shell HA scaffolds led to a significant difference (p < 0.05) in TNF-α expression (p = 0.01) and Osx expression (p = 0.01). A Pearson correlation test result showed a strong inverse correlation between TNF-α and Osx expressions (p = 0.00 and r = -0.78). Conclusion: The transplantation of HA scaffolds from crab shells can decrease TNF-α expression but increase Osx expression in the post-extraction socket of C. cobayas. Furthermore, an inverse correlation was found between TNF-α and Osx.
