Introduction: Age estimation has an important role in the process of human identification and needs to be performed in an efficient, fast, and accurate ways. Age estimation based on the pulp cavity volume of canines was referring to the theory stated that the apposition of secondary dentine during human life could be determined as an age indicator. This study was aimed to estimate the human age based on the pulp volume of canines for chronological estimation. Methods: Forty-one canine teeth from Cone Beam Computed Tomography (CBCT) 3D image sample from Dental Hospital of the Faculty of Dentistry Universitas Padjadjaran segmented into dental pulp and enamel were prepared for measurement of pulp volume using the ITK SNAP volumetric software. Descriptive analysis of pulp volume and regression equations were generated from regression analysis of pulp volume and tested for age estimation. Result: Dentine thickness was found to be increased from adolescence age range until adulthood age range. Logarithmic regression between pulp volume was statistically significant (p < 0,001). The coefficient of determination (R2) was 0.753 with a standard deviation of 8.421. Mathematics model for estimating age was: Age = 79.523 – (18.194 x ln(Pulp Volume)). The pulp cavity and dentine thickness were decreasing along the age. The same equation was also used in the same sample. There were several differences between chronological age and estimated age approximately 8.4 years following the regression result of R2 (75.3%). The rest of the sample (24.7%) have a big difference, and this could be affected by modifying variables such as occlusal force and human error measurement procedures. Conclusion: The human age can be estimated by the pulp volume of canines.Keywords: Age estimation, pulp volume, canine, ITK-SNAP, CBCT.

Introduction: Abnormalities of the dental pulp can have several different diagnoses. Therefore, the dental pulp characteristics must be known in more detail and clear so that diagnosis be established more precisely and accurately. One characteristic of the pulp can be seen from the density value through the 3D Cone Beam Computed Tomography (3D CBCT). Methods: The study was conducted with a simple descriptive method. The population is all the data 3D CBCT of patients who visited the Universitas Padjadjaran Dental Hospital (RSGM Unpad) in 2012. Samples of the research were 75 pulps with normal, inflammation, and necrosis conditions and calculate the average density value. Results: Density values for dental pulps in the normal teeth between 465 - 775 HU, the inflammation teeth between 243.5 - 396 HU, and necrosis teeth between - 461.5 - -170 HU. Conclusion: There are differences in dental pulp density between the normal pulp, inflammation and necrosis through 3D CBCT.

Introduction: One part of the most important individual identification procedure is approximate age can be done on an individual living or dead. Judging from some of the methods that have been there, have not found a method forecasts age through the frontal sinuses, particularly research conducted in Indonesia. The frontal sinus can be used for identification because the frontal sinuses began to evolve and look at radiographs at the age of 7 years and did not change after the age of 20 years, it reveals the existence of differences in the size of the frontal sinuses with age. Objective: To asses of the frontal sinus anteroposterior size based on against lateral cephalometric radiographs chronological age as forensic identification. Methods: A number of samples are 502 lateral cephalometric patient data from secondary data of patients aged 7-20 years, 335 pieces of lateral cephalometric. Purpose of of the study was to asses the frontal sinus anteroposterior size chronological age as forensic identification. Radiograph female patients and 167 pieces in male patients. Data anteroposterior size of the frontal sinus is obtained by pulling the longest line perpendicular to the line of Sh-Sl. Results: The results showed that at the age of 7 years the average size of the frontal sinus anteroposterior 4.20 mm and 5.05 mm which is the smallest size, while the average size of the biggest, by 8.46 mm in women and men at the age of 11.37 mm 20 years. Conclusions: In women, the fastest increase occurred at the age of 7-8 years, males at the age of 16-18 years. The frontal sinuses anteroposterior size increases with age, both men and women.

Introduction: Ameloglyphics is the study of enamel print patterns on the tooth surface. Enamel print patterns are unique to each individual as they differ on each tooth. The similarity of tooth prints on buccal and lingual surfaces remains questionable as no research has been conducted thus far. The premolar was chosen in this experiment due to its low risk of damage because it is protected by cheek and rarely used compared to other teeth. Thus, the results obtained will be more precise and have higher accuracy than using other teeth. This research was aimed to investigate the differences between enamel print patterns on buccal and lingual surfaces of maxillary right first premolar. Methods: An analytic study was conducted by observing and analysing a total of 34 teeth samples using the purposive sampling method. The middle third of the buccal and lingual tooth surfaces was captured directly after magnified with a stereomicroscope. Photomicrographs of samples were then analysed using SourceAFIS biometric software. This software will process the image and shows patterns of enamel print. Afterwards, the enamel print patterns were observed and classified according to Manjunath Classification. Results: The results suggested that all 34 samples show a similarity of enamel print patterns on both the buccal and lingual surfaces. The interpretations of photomicrographs were statistically analysed using the Statistical Package of Social Science (SPSS) software. The similarity may be due to the same placement of developing tooth bud, temperature, environmental factor, genetics, pressure and nutrition to the ameloblasts cells in a tooth. Conclusion: Both buccal and lingual in the samples show high similarity due to the very high frequencies of similar sub-patterns occur on both surfaces. Tooth print can be used as a valuable tool in forensic science for personal identification with good prospects in the field of forensic dentistry.
