"Complete diagnosis in dentistry needs more detail and accurate quantitative as well as qualitative jawbone trabeculation evaluation. This requires modern diagnostic radiography that in Indonesia are still very limited. One form of the periodontitis that demands more attention and detailed information due to the great efforts to overcome, is Rapidly Progressive Periodontitis, and thus this disease has chosen as a model in this study. The objective of this study to get more detail and accurate radiometric of Direct Digital Intraoral value from grading Conventional value. This methode expected to be a model of studies on jawbone quality in dentistry. The healting RPP patients as a subjects of this study. The methods trabeculation density from mandibular DDIR and conventional periapical radiographs of 116 healthy subjects and 41 RPP patients were evaluated and correlated to obtain transformation formula in the form of regression function. This study was performed Clinic of Dental Radiology and Periodontology, Faculty of Dentistry, University of Indonesia function were then used as a methode to obtain quantitative data from conventional radiographs available. The results were indicated a significant independent variables were included in the regression function (p<0.05). Therefore even no DDIR equipment available, this transformation enable dentists all over Indonesia with only conventional radiographs available, to obtain more detail quantitative trabeculation density data. The conclusion is apart from getting a methode to transform conventional radiographic data into radiometric data equal to data obtained from DDR that more detail and accurate, this study also provides the normal radiographic trabeculation density value of peron 20-40 years as data base for further studies."

"Impacted third mandibular molar seems as a common and easy case but actually a difficult one when the odontectomy proceeds. besides, another unpredicted problems ofte appear such as fractured lip, traumatized and damaged of the mandibular canal. To decide the odontectomy procedure, a dentist has to do the examination systematically. In this case, radiographic examination is very important to perceive the location as well as shape of the third molar, especially its position to the adjacent anatomic structure that has to be considered during operation. This whole view will help dentist to decide appropriate approach.A special radiographic examination enables dentist to predict the treatment result more accurately, since the location and shape of the tooth correctly perceived. With this more complete diagnostic information, an appropriate treatment plan could be arranged and unfavorable risk could be limited, therefore complication and failure could be avoided."

"Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 210-214One of the impacts of traffic accident that is often seen by a dentist is mandible fracture. To prevent deformation of mandible because of a slow management, it is better to treat the fracture as soon as possible. The treatment can be done with an open/close reduction, depending on case. An immediate management of mandible fracture is very important to prevent malunion, malocclusion, and stomatoganathic dysfunction."

"Tujuan: Mengetahui perbedaan hasil interpretasi superimposisi maksila dan mandibula antara tiga metode superimposisi pada kelompok usia non-growing ≥ 20 tahun. Metode superimposisi maksila yang diteliti adalah pada area best fit, Björk dan Skieller, serta Springate. Sementara metode superimposisi mandibula yang diteliti adalah pada tepi bawah mandibula, Björk dan Skieller, serta Springate. Metode: Tracing dilakukan pada foto sebelum perawatan (T0) dengan membuat garis panduan sella-nasion (SN) dan garis N yang tegak lurus terhadap SN serta struktur anatomis pada regio maksila atau mandibula. Sedangkan pada foto setelah perawatan (T1), tracing dilakukan hanya pada struktur anatomis pada regio maksila dan mandibula saja. Kemudian hasil tracing setelah perawatan (T1) disuperimposisikan di atas hasiltracing sebelum perawatan (T0) berdasarkan berbagai metode superimposisi maksila atau mandibula. Setelah itu garis SN dan N pada tracing sebelum perawatan dipindahkan ke atas hasil tracing setelah perawatan. Terakhir, posisi titik referensi pada maksila (titik ANS, A, dan U1) atau mandibula (titik Pog, B, dan L1) diukur jarak koordinatnya secara vertikal dan horizontal ke garis SN dan N yang berperan sebagai sumbu x dan y. Hasil: Tidak terdapat perbedaan, baik dalam dimensi vertikal maupun horizontal, mengenai hasil interpretasi superimposisi maksila dan mandibula dengan tiga metode superimposisi yang diujikan pada kelompok usia non-growing ≥ 20 tahun. Kesimpulan: Evaluasi perawatan ortodontik pada pasien usia non-growing ≥ 20 tahun menggunakan berbagai metode superimposisi maksila dan mandibula menghasilkan hasil interpretasi yang sama, baik diukur dalam dimensi vertikal maupun horizontal. Sehingga pemilihan metode superimposisi maksila dan mandibula apapun pada pasiennon-growing tidak akan mempengaruhi hasil interpretasi evaluasi perawatan, selama metode superimposisi yang digunakan tetap memperhatikan struktur anatomis yang ada.

Objectives: To compare the interpretation of maxillary and mandibular superimposition between three methods on ≥ 20-year-old non-growing patients. Three maxillary superimposition methods used during the study were best fit, Björk-Skieller, and Springate. Meanwhile for mandibular superimposition, the methods used during the study were inferior border of mandible, Björk-Skieller, and Springate. Method: Tracing was executed on pre-treatment cephalogram (T0) to construct sella-nasion (SN) line and N line which was perpendicular to SN, and also to construct anatomical structures on maxilla or mandible. Tracing at post-treatment cephalogram (T1) was executed on maxillary or mandibular anatomical structures only. Then cephalogram tracing at T1 was superimposed on T0 based on three different superimposition methods on maxilla or mandible. SN line and N line at T0 were then transferred into T1 tracing as a reference line of x and y axis. Hence, the position of maxillary reference points (ANS, A, and U1) or mandibular reference points (Pog, B, and L1) could be accounted vertically and horizontally to the x and y axis. Results: No statistical difference in vertical or horizontal dimention, regarding the interpretation of maxillary and mandibular superimposition between three methods on ≥20-year-old non-growing patients. Conclusion: Post orthodontic treatment evaluation on ≥ 20-year-old non-growing patients using varied maxillary and mandibular superimposition methods may result the same interpretation in vertical or horizontal dimention. Any maxillary or mandibular superimposition methods could be used on non-growing patients and may not affect interpretation on post treatment evaluation, as long as the used methods account any existing anatomical structures."

"multipotent mesenchymal stem cells from bone marrow are expected to be a somatic stem cell source for the development of new cell-based therapy in regenerative medicines. however, dental clinicians are unlikely to carry out autologous cell/tissue collection from patients (i.e. marrow aspiration) as a routine procedure i their clinics; hence, the utilization of bone marrow stem cells seems impractical in the dental field. dental tissues harvested from extracted human teeth are well known to contain highly proliferative and multipotent stem cell compartments and are considered to be an alternative autologous cell source in cell-based medicine. this article provides a short overview of the ongoing studies for the potential application of dental stem cells and suggests the utilization of 2 concepts in future regenerative medicine: (1) dental stem cell-based therapy for hepatic and other systematic disease and (2) tooth replacement therapy using the bio engineered human whole tooth, called the "test-tube dental implant." regenerative therapies will bring new insight and benefits to the fields of clinical medicine and dentistry"
