Antibacterial Activity of Chitosan from Haruan Fish (Channa striata) Scales against the Bacteria Actinomyces spp.
Pendahuluan: Salah satu bahan alami yang sering dimanfaatkan oleh masyarakat Kalimantan Selatan adalah ikan Haruan yang mengandung kitin dan digunakan sebagai bahan antibakteri dengan cara diolah menjadi kitosan. Kitosan mengandung gugus amino polisakarida yang dapat menghambat pertumbuhan Actinomyces spp. Saluran akar gigi yang nekrosis banyak ditemukan bakteri anaerob seperti Actinomyces spp. Salah satu bahan irigasi perawatan saluran akar yang menjadi gold standard adalah sodium hipoklorit 5,25%. Namun, masih memiliki kekurangan sehingga perlu bahan alami sebagai alternatif. Tujuan: Menganalisis aktivitas antibakteri kitosan dari sisik ikan Haruan (Channa striata) terhadap bakteri Actinomyces spp berdasarkan nilai KHM dan KBM. Metode: Penelitian ini adalah true experimental dengan posttest only with control group design menggunakan empat perlakuan dengan lima kali pengulangan. Nilai KHM diukur menggunakan Spektrofotometer 722 UV-Vis dan nilai KBM dihitung menggunakan colony counter. Hasil: Nilai KHM kitosan sisik ikan Haruan didapatkan pada konsentrasi 1,25% dan nilai KBM pada penelitian ini masih belum ditemukan. Hasil uji One Way ANOVA untuk KHM dan Kruskal Wallis untuk KBM menunjukkan perbedaan bermakna (p<0,05). Kesimpulan: Terdapat aktivitas antibakteri kitosan sisik ikan Haruan terhadap Actinomyces spp berdasarkan KHM pada konsentrasi 1,25%, namun belum setara dengan sodium hipoklorit 5,25% dan tidak terdapat aktivitas antibakteri kitosan sisik ikan Haruan terhadap Actinomyces spp berdasarkan KBM
Lay Person's Esthetic Perception of Black Triangles Using Q -Sort Assessment and Visual Analog Scale
Objective: To evaluate the perception of laypersons regarding black triangles between the maxillary central incisors on the esthetics of smile. In addition, we also evaluated the difference between the two grading systems used i.e., Visual analog scale and Q sort assessment. Methods: A picture at smile was manipulated using Photoshop (CC 2019; Adobe Systems) computer program. Black triangles of different sizes were then created between the maxillary central incisors in the embrasure areas. Multiple photographs were generated, and they were evaluated via Visual analog scale and Q sort assessment method by 161 laypersons. Result: The results showed that the larger the black triangle the less attractive the images were rated, regardless of the assessment method used. The presence of no black triangle or a small black triangle (0.5 mm) resulted in the highest scores in both methods. Conclusions: The most attractive image with both assessment methods was the one without any black triangles. Q- sort assessment method is comparable to VAS method in assessing smile esthetics with Laypersons showing consistent agreement in identifying unattractive and attractive smiles. Both assessment methods (VAS scale and Q-sort) showed correlation value=0.9
Radiographic finding of sunray appearance as a sign of malignant mandibular lesion: a case report
Objectives: To report the “sunray†appearance on panoramic radiography as a sign of malignancy lesions of the mandible.
Case Report: A 40 year old female patient came to the Hasanuddin University Dental Hospital with the main complaint of facial swelling which causes an asymmetrical appearance and hard consistency on palpation. Mucosa around the second right premolar to the third right molar is reddish with an irregular border. The patient was referred to the radiology department for panoramic radiography and MRI. The panoramic radiograph revealed a mixed radiolucent-radiopaque lesion in tooth 35 involving ramus to the coronoid process. PDL space was irregular widening at 36, 37, and 38. The "sunray†appearance was seen from the ramus extending to the coronoid process. On the MRI, a mass on the submandibular gland pushed and narrowed the sublingual, parapharyngeal, and masticator space, destroying the mandible on the left side. These radiologic findings strongly suggest a malignancy involving the jawbone.
Conclusion: The findings of a mandibular malignancy in the form of a “sunray†appearance on panoramic radiography need to be confirmed with an MRI examination to determine the consistency and extent of the lesion to the surrounding tissue. A comprehensive examination is necessary to properly diagnose mandibular malignant lesions so that the most suitable treatment plan can be determined
Quality assurance of oral and maxillofacial teleradiology: a literature review
Objectives: This article aims to inform dentists and dental specialists about quality assurance in oral and maxillofacial teleradiology as a communication tool between radiologists and colleagues using a teleradiology system.
Review: Teleradiology is a radiological practice that allows the transmission and interpretation of diagnostic images, such as intraoral, extraoral, and CT scans, from different geographic locations. In dentistry, oral and maxillofacial radiologists often interpret these images remotely. To be effective diagnostically, teleradiology must maintain high-quality imaging standards and follow radiological care principles. Quality assurance (QA) plays a vital role in ensuring image clarity, diagnostic accuracy, and patient safety. QA involves implementing standard protocols for image acquisition and transmission using systems such as DICOM (Digital Imaging and Communication in Medicine) and PACS (Picture Archiving and Communication System), under radiologist supervision and with professional collaboration. Compression formats like JPEG and wavelet, whether lossy or lossless, must be managed properly to avoid image degradation. In clinical dental practice, teleradiology is utilized through teleconsultation, tele-consultancy, and telemanagement, relying on secure communication networks and professional interaction to protect data integrity and confidentiality.
Conclusion: Teleradiology improves access to radiologic interpretation and secondary consultations while offering flexibility in image review. Images can be simultaneously accessed from multiple locations. Successful implementation requires proper compression, stable internet, patient privacy, authentication, and data integrity. With adequate QA measures, teleradiology significantly enhances diagnostic services and patient care outcomes.

Pengaruh Suhu Ruangan Terhadap Distorsi Perubahan Dimensi Wax Selama 24 Jam: The Effect of Room Temperature on Wax Dimensional Change Distortion for 24 Hours
Wax is a soft and flexible material obtained from plants and insects or made synthetically and composed of high molecular weight organic molecules. One of the properties of dental wax or wax is the property of distortion, namely the return of the modified form of dental wax or wax to its original shape. Wax patterns or wax models are used as wax patterns in the manufacture of orthodontic appliances, complete dentures, and other prostheses that use plastic construction. Base plate wax is a dental wax for denture patterns based on acrylic resin. To evaluate wax distortion that occurs at room temperature for 24 hours. Testing of 141 wax samples placed at room temperature 25°C for 24 hours. One-way ANOVA test revealed a significant difference (p<0.05) in storage of wax at room temperature for 24 hours. There is an effect of temperature and storage time on the amount of wax distortion that occurs.
 
Mandibular osteomyelitis on panoramic radiographs: a case series
Objectives: This series of cases aims to see an extension of a lesion using panoramic radiographs to help establish a diagnosis in three cases in the mandible. Osteomyelitis occurs more often in the mandible than in the maxilla because the maxilla has a better blood supply than the mandible, with relatively thinner cortical and fewer medullary cavities.
Case Report: Three female patients presented with nearly identical complaints, including frequent pus discharge, unpleasant odor, and swelling. Only two of the patients had a history of tooth extraction. All three were referred to the university dental hospital (RSGM) for further management. Panoramic radiographs revealed similar findings among the three cases, including mixed radiopaque-radiolucent images with irregular shapes and diffuse borders. In two patients, sequestra were visible in the right and left corpus regions of the mandible. In contrast, the third patient showed a slightly different presentation: a well-defined, irregular radiopaque mass protruding from the top of the alveolar bone, localized at the crest of the ridge. One of the patients had a history of systemic diseases, specifically hypertension which was under control.
Conclusion: In these three cases, a panoramic X-ray examination was the only support for identifying the characteristics of lesion expansion and was considered sufficient as a reference for patient management. However, a definitive diagnosis still requires a histopathological examination
Indications for CBCT examination in pediatric patients: a cross-sectional study
Objectives: This study aims to portray the characteristic of cone beam computed tomography (CBCT) indication on pediatric patients based on age, gender, specialist field, clinical indications, and radiation doses.
Materials and Methods: CBCT images of 55 pediatric patients were investigated retrospectively. CBCT images were obtained with three categories field of view (FOV). CBCT indications were categorized as dental anomalies, impacted teeth, orofacial cleft, orthodontic needs, endodontics, osseous pathological lesion, dentoalveolar trauma, and temporo mandibular disorder. The effect of age, sex, and FOV were evaluated.
Results: The most common indication for using CBCT is impacted teeth (45%), osseous pathological lesion (17%), and dentoalveolar trauma (11%). There were not significant association between sex, age group, and FOV to CBCT indication.
Conclusion: CBCT examination at Dental Hospital of Hasanuddin University is needed in pediatric patients mainly to diagnose oral pathology, impacted teeth, and dentoalveolar trauma. Determining CBCT for pediatric patients should be indicative-oriented suitably with as low as diagnotically achievable being indication-oriented and patient-specific (ALADAIP) principles
Evaluation of unilateral condyle head fracture on panoramic and CBCT imaging: a case report
Objectives: This case report aimed to describe the radiographic characteristics of the fracture of the condyle’s head and its impact on surrounding tissues in a young adult patient using panoramic and CBCT radiographs.
Case Report: A 19-year-old female patient presented to the Dental Radiology Unit of Dental Hospital Universitas Padjadjaran with a panoramic and periapical referral letter, diagnosed clinically with a dental fracture of the upper left central incisor, and planning to have orthodontic treatment. The patient had a history of a motorcycle accident in early January 2024 and was hit on the left side of her face. Extraoral examination revealed an asymmetrical facial appearance with mandible deviation, mouth opening limitation, and crepitation on palpation test. Intraoral examination showed a traumatic ulcer in the upper left lip region (tooth 22) and a dental fracture on tooth 21. Oral hygiene was in good condition. The first panoramic radiograph (January 19th, 2024) showed a fracture on the right condyle’s head. It referred to taking the CBCT examination (May 28th, 2024) to know the exact position and the destruction of the condyle’s head. The CBCT examination showed a radiolucent line crossing horizontally on the left condyle’s head; the joint space was larger than on the other side.
Conclusion: Based on the CBCT results in terms of location and radiographic feature, this radiolucent line led to a suspect radiodiagnosis of unilateral fracture on the left condyle’s head that causes pain and limited mouth opening.

Odontogenic sinusitis due to radix perforation into the maxillary sinus on CBCT radiograph: a case report
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
Kekuatan Fleksural Dentin setelah Eksposur Semen Bioaktif: Dentine Flexural Strength after Bioactive Cement Exposure
Bioactive cements are used widely in dentistry, especially in restorative and endodontic field. Bioactive cement can induce response from living tissue, organism, or cells by hydroxyapatite layers formation when in contact with tissue fluid. Despite of its benefit, bioactive cements use as root canal medicament can caused dentinal collagen damage that can lead to tooth fracture. This literature study objective is to analyse dentinal flexural strength after bioactive cements exposure by literature study. Literature study results show that every bioactive cement exposure can decrease dentin flexural strength that can lead to root canal treatment failure. Bioactive cement composition that effect dentin flexural strength in long term use is Calcium Hydroxide. Long term clinical test of bioactive cement from different generation need to be evaluated on next study
