PurposeThis study was performed to evaluate the changes of jaw bone density around the dental implant after placement using computed tomography scan (CT-Scan).Materials and MethodsThis retrospective study consisted of 30 patients who had lost 1 posterior tooth in maxilla or mandible and installed dental implant. The patients took CT-Scan before and after implant placement. Hounsfield Unit (HU) was measured around the implants and evaluated the difference of HU before and after implant installation.ResultsThe mean HU of jaw bone was 542.436 HU and 764.9 HU before and after implant placement, respectively (p<0.05). The means HUs for male were 632.3 HU and 932.2 HU and those for female 478.2 HU and 645.5 HU before and after implant placement, respectively (p<0.05). Also, the jaw bone with lower density needed longer period for implant procedure and the increased change of HU of jaw bone was less in the cases which needed longer period for osseointegration.ConclusionCT-Scan could be used to assess the change of bone density around dental implants. Bone density around dental implant was increased after placement. The increased rate of bone density could be determined by the quality of jaw bone before implant placement.

The aim of this literature review was to study the underlying mechanisms of the association between periodontal disease and prostate cancer. Methods: This study was literature review study, pubmed searching was used to find scientific article about association of periodontal disease and prostate cancer. Results: Direct correlation between periodontal disease and prostrate cancer is still unclear. It was hyphotesized that microorganisms involved in chronic periodontitis may directly induce mutations in the tumor-suppresor genes and proto-oncogenes or alter the signalling pathways that in turn stimulates cancer growth. Conclusion: Periodontal disease may associate to prostate cancer by mutation induction in tumor-suppresor genes.

Panoramic radiography is a technique to yield face structure photo including bone ofmaxilla, mandible and supporting structures like maxilla antrum, nasal fossa, TMJ,procesus styloideus, and os. hyoid. Panoramic radiography is also used to evaluateasymmetrical of face. Growth and development of head is similar to the growth anddevelopment of body in general. The skeletal morphology can be disturbed by internaldisorder of TMJ and degenerative joint disease as short ramus, a sharp angle of mandible,and also cranial base that cause asymmetrical face. By taking accurate panoramicradiography, the mandible asymmetrical can be measured.

Background.Choronological age is assessed by the date, month, and year of birth. Several researches suggested that Chronological age may not be able to provide sufficient information regarding on human growth precisely. Chronological age, on the other hand, could not be used to assess  Maturity development rate of a patient, so it is necessary to assess the dental age. Dental age is age assessment method  by measuring human growth and development. Age estimation has important role in health field, Particularly  in dentistry as it will be beneficial in making appropriate diagnosis, Treatment plan, and prognosis. Tooth eruption estimation according to Demirjian Method conducted by assessing growth and development process of tooth using panoramic  radiography. Purpose. Determine the difference between Chronological Age and Dental Age Using Demirjian Method Based on Radiology Analysis of Panoramic Radiography. Method. This study was an observational analytic using Cross-sectional study, all data are observed once at the time. In this study,  the amount of sample reviewed were 30 samples, consisted of 4 – 9 years old children. Panoramic radiography were collected based on target population which fulfill Sample Criteria from reconciled patient of radiology department RSGM Unhas. The results were obtained by estimating the score of  dental age using Demirjian Method. After that, the Dental age and chronological age were analayzed to obtain the mean difference. Result. Based on wilcoxon test, mean value was obtain p:0.011 (p<0.05), this result shows that there is significant difference between chronological age and dental age. Conclusion.Chronological age and dental age can be assessed by reviewing the panoramic radiography using Demirjian Method

Nasopharyngeal cancer has different malignancy types, based on its location. Themost frequent type of nasopharyngeal cancer is carcinoma of squamous cell whichhappens on cells inside nose, mouth, and throat. The rare types happened such assalivary gland tumor, lymphoma, and sarcoma. There are three main therapies totreat nasopharyngeal cancer; they are radiation therapy, surgery, and chemotherapy.The main treatment is radiation therapy or surgery and chemotherapy or combinationboth of them. Chemotherapy is often conducted as an additional treatment.Combination treatment between those three treatments optimally can be used fornasopharyngeal cancer patient based on the location and disease stadium. Radiationtherapy on nasopharyngeal cancer can caused some side effects, such as mucositis,salivary gland dysfunction, taste sense dysfunction and malnutrition, tooth disorders,bone transforming, cutaneous transforming, nerve disorders, decreasing ofintellectual, lost of hearing sense, complication of malignant cancer caused byradiation, and intracranial bleeding.
