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.

In the past, dental implant (DI)treatment is still an exclusive treatment can only beachieved by high class people due to unaffordable cost. However, nowadays thedemand of DI become increasing. The success of DI insertion is determined by thecondition of alveolar bone itself. Although there is no studies of DI treatment failurein Indonesia, there are some reports studied failure of DI treatment assessment whichcould be caused by the lack of quality and quantity of the alveolar bone radiographyimage. The purpose of this article was to introduce the benefit of hounsfield unit at theCT-Scan in supporting assessment of alveolar bone compactness for DI insertion. Itcan be concluded that the use of hounsfield unit at the CT-Scan can provide theclinician in determining the alveolar bone compactness prior to the DI treatment thatcan decrease the failure to occur.

Objectives: The most commonly encountered impacted tooth is the third molar, and potential problems include oral cysts and tumors as well as caries, periapical lesions, periodontal disease, TMJ disorders, and root resorption of adjacent teeth. The aim of this investigation was to determine the third molar impaction prevalence and pattern. Materials and Methods: 530 panoramic radiographs of patients who visited Hasanuddin University Dental Hospital from January to December 2020 were collected. Data were recorded based on third molars region, eruption level, angulation, and impaction class from radiographs that met the criteria on Excel sheets and analyzed using SPSS 26. Chi square test was performed to assess relationship between impaction patterns with age and gender. The level of significance was fixed at p<0.05. Results: 115 radiographs were included and analyzed (45.2% male and 54.8% female). Third molar impaction prevalence was higher in females, in the age group 21-30 years, with level A eruption and vertical angulation. Most #38 and #48 demonstrated class 2 impaction. Apart from angulation and impaction class on #38, there was no significant difference between impaction patterns by age and gender group (p>0.05). Conclusion: Third molar impaction was more common in women aged 21-30 years with a dominant impaction pattern at level A with vertical angulation. In the mandible, class 2 of the Pell and Gregory classification are known to be dominant in third molar impaction.

The development of radiological technology has provided many contributions not only in widening the science ofradiology and diagnostic capabilities, but also in radiation protection to the patient as low as possible in accordancewith the clinical need. This is an important aspect in diagnostic radiology services that need continuous attention. Thisstudy aims to determine the knowledge level of Dental Health Polytechnic Makassar on radiation protection in x-rays.With cross sectional method, the sample was students of Makassar Dental Health Polytechnic, semester II and IV. Theresults showed that the number of respondents who have a very good knowledge as much as 2.343%, good as much as22.656% category, quite good as much as 40.625 %, the poor as much as 18.75%, and the category not good as muchas 15.625%. It was concluded that knowledge about x-ray radiation protection of Dental Health Polytechnic Makassar student is still lacking.
