Objectives: This research is aimed do find out the differences of interprocessus distances between males and females using panoramic radiographs. Materials and Methods: This research is using observational analytic with cross sectional study design. Secondary data was taken from 96 panoramic radiographs consisting of 48 males and 48 females, from RSKGM-P Universitas Airlangga. Measurements were carried out using ImageJ Software by 3 observers. The measurement results were then analyzed by independent t-test and the inter-measuring reliability was tested using the Intraclass Correlation Coefficient (ICC) on IBM SPSS software. Results: The result showed that the significance value (2-tailed) of interprocessus distances measurement on males and females was <0.05 in both regions. Reliability test of inter-observer using ICC obtained the overall measurement results was more than 0.75 which means excellent reliability. Conclusion: There was a significant difference between the interprocessus distances on males and females as measured by panoramic radiographs.

Objectives: This study is aimed to find out the distribution of DBI in the jaw based on the classification of radiopaque areas and their location using panoramic radiographs at RSKGMP Universitas Airlangga Surabaya. Materials and Methods: This research was a descriptive observational study with total sampling method. The study used secondary data from panoramic radiographs at the RSKGMP Airlangga University Surabaya during 2018–2021, which had a DBI appearance, and analyzed them based on the classification of radiopaque areas and locations. The results of the analysis are then presented in the form of tables and pie charts. Results: Classification of DBI based on radiopaque areas was found in type 5 separate (47.81%), type 4 apical (29.82%), type 3 apical and interradicular (17.54%), type 1 interradicular (3.07%), and the least in type 2 interradicular and separate (1.75%). The most common locations of the lesions were in the premolar region (42.54%), the molar region (27.63%), the canine region (12.28%), the canine-premolar region (8.33%), the premolar-molar region (6.58%), and the least common location in the incisor and incisor-canine regions (1,32%). Conclusion: Classification of DBI based on the most common radiopaque area was found to be type 5 separate, with the most lesion locations in the premolar region. While the least classification was found in type 2 interradicular and separate, the incisive and incisive-canine regions had the fewest lesion locations.

Age estimation is an important aspect in forensics because it plays a role in determining individual identity. In cases of forensic identification of bodies that are difficult to identify visually or in poor condition, radiography is the choice of non-invasive method that can be used for age estimation, one of which is panoramic radiography. The Tooth Coronal Index (TCI) method is one method that can be used to identify a person's biological age through panoramic radiography. The purpose of this study was to compare the chronological age with the biological age obtained from the measurement of the TCI method on the mandibular premolars using panoramic radiography in the Malang City population. TCI measurement was done by measuring the height of the pulp chamber (Coronal Height) and the height of the crown of the tooth (Coronal Pulp Cavity Height) vertically from the Cemento Enamel Junction (CEJ) on the mandibular premolars. Then the value is entered in the regression equation that has been determined to obtain an estimate of biological age. Then, the results of the estimated biological age are compared with their chronological age. At last, the difference between biological and chronological age is calculated to determine the approximate age. The mean difference between chronological age and biological age was ± 1.32 years and there is no significant difference between the biological age and the chronological age (p value 0.11). TCI method on the mandibular premolars using panoramic radiography can be used to estimate age in Malang City Population.

Bite marks as evidence of a crime cases are commonly found in cases such as sexual assault, struggle, homicide and child abuse. Bite marks are thought to help uncover the biter because human teeth are individualistic and have different shapes, sizes and patterns for each individual, even identical twins. This report is to explain how to analyze bite marks using a "stamping" method in child abuse cases. In this case report, we present a case of 17-month-old toddler who was found dead in his house with head trauma and two scars resembling human bite marks on the right chest and abdomen. Those scars appeared not as a new bite and that implies these bites happened before the death of the toddler. Investigators assumed that he was a victim of child abuse which led to the murder. Although the autopsy results showed the cause of death was not from the bite but from the blunt object trauma to his head, by analyzing the evidence of bite marks found on the victim's body it can be expected to provide information about the motives and background of the murder and help find the perpetrator of the bite-related injury. Analysis was done by using a "stamping" method of the suspect's bite marks who was asked to bite a wax that had been flexed with heat and then superimposed with a photo of bite marks on the victim's body with a size close to the actual size. The result showed that the bite marks matched the bite of the victim's father who was also suspected of being the murderer. The bite pattern of the toddler's father had similarity with the bite marks found on the victim's body, so he has possibility to be included as the suspected biter.

Objectives: This study aims to find out the distribution of CBCT-3D examination referrals at Dental Hospital Universitas Airlangga based on the origin of referral, specialist field, age and gender. Materials and Methods: This descriptive research is using the total sampling method. Secondary data from the medical records of any referral patients for CBCT-3D examination at Dental Hospital Universitas Airlangga from July 2015 to March 2020 were included in this study. Furthermore, data references were tabulated and presented in the form of a pie chart. Results: The distribution of CBCT-3D examination referrals at Dental Hospital Universitas Airlangga was as high as 323 (77.64%) coming from within the hospital and as much as 93 (22.36%) from outside of the hospital. Based on the dental specialties who made the referral, six of seven departments have referred their patients for CBCT examination with varying proportions and indications. The distribution of referrals was also divided into gender (male or female) and several age categories based on the Indonesian Ministry of Health, such as toddlers (ages 0-5 years), children (ages 5-11 years), adolescents (ages 12-25 years), adults (ages 26-45 years), elderly (ages 46-65 years) and seniors (over 65 years). Conclusion: Referrals for CBCT-3D radiography examinations at Dental Hospital Universitas Airlangga are mostly from within the hospital, from the Department of Oral and Maxillofacial Surgery. Female patients and the elderly (46 years and older) were found to be the most frequently referred.
