Abstract

Background: Dentigerous cyst is a cyst that forms around the crown of an unerupted tooth. It begins when fluid accumulates in the layers of reduced enamel epithelium or between the epithelium and the crown of the unerupted tooth. Dentigerous cysts attach to the cementoenamel junction. Some dentigerous cysts are eccentric, developing from the lateral aspect of the follicle so that they occupy an area beside the crown instead of above the crown. In the case of dentigerous cysts with supernumerary, lesions appear to develop in the lateral aspect, so proper imaging is needed to see the expansion of the lesion. A modality that can be used to see the location and expansion of dentigerous cysts is by using a CBCT radiograph. Objective: Identification and interpretation of dentigerous cysts with supernumerary using CBCT radiography. Case Report: 12-year-old male came to the RSGM FKG Unpad bring a referral letter for CBCT photos. From the history it is known that the patient has a complaint of teeth that have not grown with swelling in the right maxilla. Case Management: Using CBCT, there were supernumerary and dentigerous cysts at 14,13. Sagittal, coronal and axial CBCT features show the position and condition of supernumerary, and give information about the location and expansion of dentigerous cyst at 14,13. Conclusion: CBCT provides a description of dentigerous cysts about location, lesion expansion, and involvement with surrounding tissue. CBCT provides an overview of lesions in sagittal, coronal and axial

Abstract

The condition of oral cavity greatly influences the patient's dental care and treatment. In prosthodontic treatments, the anatomy and arrangement of the teeth is one of the factors that must be considered in order to be able to plan a treatment design. Deep bite with larger overlap of the maxillary and mandibular incisors make the lateral load borne by the teeth become greater. This can cause damage to the tooth and periodontal tissues, as well as failure of the denture. This article reports on the treatment of edentulous of the tooth 21 with deep bite with convetional brigde PFM. Clinical examination showed that there was an overlap between the upper central incisors and the lower incisors by 5 mm and there was a toothwear defect in the form of attrition on teeth 31 and 41. The patient was planned to have a 3 unit conventional bridge made with porcelain fused to metal with a metal backing design to reduce the thickness of the preparation in palatal area and minimize contact with opposing teeth. At the insertion, the patient's occlusion is checked and evaluated so that there are no premature contacts and occlusal interference during centric and eccentric movements. The patient is satisfied with the results of the treatment. Treatment with fixed partial denture in deepbite must be well designed and planned to achieve successful treatment.

Abstract

Objectives: The aim of this case report is to describe radiographically the specific features of bifid mandibular condyle that frequently found incidentally on panoramic radiographs. Case Report: A 24-year-old man came to the Installation of Dental Radiology RSGM UNPAD brought a referral letter for a panoramic photograph. From anamnesis is known patient have complaints of pain in the jaw joints left and right at the time of open mouth. Panoramic radiographs show mesioangular dental impaction of 48, and edentulous tooth 36 and presence of bifid condyle on the right and left condyle. Bifid condyle usually becomes incidental finding on routine panoramic radiographic examination. Bifid condyle features can be shown by depression or notch on the superior surface of condyle. Bifid condyle can provide a "heart-shaped" from the frontal view. For a definite feature can be seen with other modality such as CBCT. Sometimes there is also a change in the mandibular fossa to compensate the morphological changes of the condyle. Conclusion: Bifid condyle mandible is a variation in the shape of the condyle whose cause is not known with certainty. The bifid condyle gives the "heart-like" appearance that is often found on accidental panoramic radiographs. Generally, cases of BMC do not require treatment unless they cause symptoms.

Abstract

The number of elderly people in the world continues to increase annually, including in Indonesia. Over more than a decade(2010–2021), the percentage of the elderly has climbed by at least 3%, reaching 10.82 %. Age-related conditions that negatively affect the physical and mental well-being of the elderly, such as xerostomia and hyposalivation, can lead to a decline in oral function Purpose:This study aims to determine the condition of xerostomia and hyposalivation in elderly patients at the Andalas University Dental and Oral Hospital (RSGM UNAND). Methods:This study usedcross-sectional design, using a total sampling technique involving 35 elderly patients with full edentulous conditions who came to UNAND General Hospital within 3 months. Xerostomiais carried out using a questionnaire that has been tested for its validity and rehabilitation, then salivary flow rate are carried out using the unstimulated saliva collection method to determine the condition of hyposalivation The data was analyzed by computerized by usingspearman test to analyze the relationship between the condition of xerostomiaand hyposalivationang sociodemographic aspects.Results:41.4%of patients had hyposalivation, thus xerostomia affected all patients (62.9% exhibiting low and 37.1% highcomplaint). Theaverage saliva flow rate was 0.51±0.303, and there was no correlation between saliva flow rate and sociodemographic aspects. (p>0.05).Conclusion:Some elderly patients with full edentulous conditions experience hyposalivation and xerostomia conditions caused by lack of salivary production due to aging factors

Abstract

Image quality enhancement of panoramic radiographs using the Laplacian filter method has been carried out. This study aims to improve the quality of panoramic radiography images (Acteon X-Mind Prime 3D) in the radiology installation of RSGM Andalas University. This study used secondary data from 46 panoramic images in .BMP format, which were performed by applying Laplacian filter and evaluating image quality by Structural Similarity Index (SSI), Contrast-to-Noise Ratio (CNR), Contrast Improvement Ratio (CIR) and Spatial Frequency (SF). The results showed that the SSI value was 0.636 ± 0.0732, CNR 5.36 ± 0.412, CIR 0.740 ± 0.124, SF 0.605 ± 0.0983. These results mean that CNR shows good image contrast, SSI shows dissimilarity between the original image and the image after Laplacian filter processing, CIR shows good contrast improvement, while the SF value of 0.749 indicates that the image's ability to display structural details is still lacking. Skewness and Shapiro-Wilk tests indicate that SSI and SF are abnormally distributed, while CIR and CNR are normally distributed. T-test analysis was performed on the CIR and CNR metrics data, which showed that the significance of this study indicated that the Laplacian filter method was significant p < 0.001. Thus, the use of the Laplacian filter method significantly improves the image quality of panoramic radiographs.

Abstract

Objectives: The purpose of this article was to provide an overview and examination guide in identifying odontogenic sinusitis due to radix perforation into the maxillary sinus by dental action or iatrogenic in dentistry using the CBCT modality. Case Report: A 33-year-old female patient presented to the Radiology Installation of RSGM Andalas University with a referral for CBCT, following a diagnosis of odontogenic sinusitis. According to the patient’s medical history, she had been experiencing headache and dizziness for five months after a tooth extraction. The CBCT scan revealed remnants of a tooth root (radix) perforating into the right maxillary sinus, surrounded by a radiopaque intermediate area. Sinus perforation is a known occurrence in dentistry, and it requires thorough diagnostic imaging for proper evaluation. The tooth root remnants are typically located in the premolar and molar regions, near the base or medial wall of the sinus. The size of the tooth fragments within the sinus can be precisely measured, and the relationship of the remaining fragments to the maxillary sinus anatomy can be clearly defined. This detailed information enables clinicians to assess the extent of the lesion and its impact on surrounding structures, allowing for the development of an appropriate treatment plan for the patient. Conclusion: CBCT is a very adequate modality for supporting the examination of cases of residual tooth roots perforated to the sinuses because it can provide detailed information about the position, size, and relationship with the surrounding anatomy.
