Medical records, samples, and photographs taken BEFORE/PRIOR TO DEATH. Include fingerprints, dental xrays, body tissue samples, photographs of tattoos or other identifying the victim | ANTEMORTEM RECORD |
Records before death | ANTEMORTEM RECORD |
The objective is to recreate what the individual’s dentition and oral structures were at the time of his last dental visit | ANTEMORTEM RECORD |
Locating Antemortem Dental Records | local VA hospital, asking a family member for the name of the deceasedindividual’s treating dentist , local dental schools, individual’s personal phone book or in their household financial records, dental records from any prior incarceration, Job-related insurance companies, Public Health Department Dental Clinics (LALIDJP) |
essence of all postmortem examinations | Accurate documentation |
By means of _____, ______, and _____, the forensic odontologist can precisely document the dental conditions that may lead to a positive identification | clinical charting, photographs, postmortem radiographs |
Records after death | POSTMORTEM RECORD |
Examination of dead body to determine the cause of death | POSTMORTEM RECORD |
A_____ of a disease individual is a core task in forensic odontology along with determining the manner and cause of death the medical examiner or the coroner as statutory responsibility and authority to identify the disease and issue a death certificate | FORENSIC DENTAL IDENTIFICATION |
Methods of Human Identification:Not a footprints but more of the body itself | Visual |
Methods of Human Identification:Is a non-specific method but is often used by the medical examiner when there is no significant question as to who the individual is, the remains are intact, nondecomposed, and viewable, and/or the death was witnessed | Visual |
Methods of Human Identification:Tattoo, skin etc. | Visual |
Methods of Human Identification:Is an excellent biometric method of human identification when the soft tissue of the fingers is intact, | Fingerprints (Ridgeology) |
Methods of Human Identification:has the advantage of a large known national and international database and it does not require a presumptive identification to obtain antemortem information | Fingerprints (Ridgeology) |
Methods of Human Identification:another biometric method of identification that relies on the unique characteristics of the skeleton, comparing post-mortem radiographic imaging with antemortem imaging and written records | Anthropology/ Radiology |
Methods of Human Identification:biometric methods of identification | DNA |
Methods of Human Identification: comparison relies on accessible antemortem data | DNA |
Methods of Human Identification:most common biometric method for identifying burned, decomposed, skeletonized, and fragmented remains for multiple reasons | Dental |
Methods of Human Identification:In mass fatality incidents, it is often the most expedient method for identifying burned, fragmented, and decomposed human remains. | Dental |
Is made most often by the investigating agencies this is often based on the circumstantial evidence and can assist in the accumulation of medical and dental records to be used in the scientific identification process. | Presumptive Identification |
What Antemortem Dental Records Should Be Requested? | All dental records of the decedent should be requested, both written and radiographic. |
Classification of remains: Class I | fresh |
Classification of remains: Class II | decomposed/ incinerated |
Classification of remains: Class III | skeletal |
Examination Procedures:Visually identifiable body | Photographs; Radiographs; Dental charting; Dental impressions, if applicable; Resection, if needed |
Examination Procedures:Decomposed/incinerated body | Photographs, Radiographs, Dental charting, Resection and preservation of jaw specimens if indicated |
Examination Procedures:Skeletonized remains | Photographs; Radiographs; Dental charting |
Images take should include: | Full face, Full-face lips retracted, Close-up of anterior teeth in occlusion, Lateral views with teeth and in occlusion, Occlusal views of maxillary and mandibular teeth, Any other photographs should be taken of unique findings |
If the remains are fragmented, skeletonized, or burned, the odontologist should capture sufficient photos to document __________and any areas of special interest. | all surfaces of teeth |
TRUE OR FALSE: Taking photographs both before and after cleaning of the specimens may help to document the process of identification and may record evidence, which may become useful later in an investigation | TRUE |
TRUE OR FALSE: A robust photographic documentation should ideally be obtained using a suffiient quality camera and lens. | FALSE |
TRUE OR FALSE:A full mouth series of radiographs should ideally be taken on all remains | TRUE |
TRUE OR FALSE:dental fragments, dissociated teeth, bone, and restorations do not need to be documented | FALSE |
TRUE OR FALSE:Resection of the soft and hard tissue is often necessary to gain proper access to the jaws | TRUE |
TRUE OR FALSE:panoramic contains more details than periapical | FALSE |
a postmortem change resulting in the stiffening of the body muscles due to chemical changes in their miobrils | Rigor mortis |
Restricted access to the oral cavity in order to perform an examination with radiographs may often be difficult due to ____ | rigor mortis |
helps in estimating the time since death as well to ascertain if the body had been moved after death | rigor mortis (viewable remains) |
Rigor Mortis Stage:destruction of a cell/ tissues by their own enzyme | Stage 1 (Autolysis) |
Rigor Mortis Stage:skin shade starts blurring because of the sulfur-containing mixes discharged by the bacteria in the body. | Stage 2 (Bloat) |
Rigor Mortis Stage:As a result, a foul odor is produced by the microorganism during the process of putrefaction, which is the formation of pus. | Stage 2 (Bloat) |
Rigor Mortis Stage:fluids release through the orifice indicate the beginning of the active decay. Such as organs, muscles, skin. | Stage 3 (Active Decay) |
Rigor Mortis Stage:Liquefaction stage. | Stage 3 (Active Decay) |
Remains that are not visually identifiable such as decomposed or burned remains, it may be advantageous to surgically reflect the overlying soft tissues in a manner that gains an ease of access that allows for a complete examination. | Nonviewable Remains |
Prior to any soft-tissue exposure or excision of the jaws, permission is necessary from the ___________even if the remains are considered nonviewable | coroner or medical examiner |
Methods (surgical for nonvieable remains): In cases where the remains are badly decomposed, burned, or fragmented | Jaw Resection |
the blade of the saw move back and forth to cut a linear line through hard cast material without cutting the soft human tissue | Stryker Saw Method |
Methods (surgical for nonvieable remains): An alternative technique for the resection of the jaws involves the use of large pruning shears. | Pruning Shears Method |
can be used to induce a “Le Fort” Type I fracture of the maxilla | Mallet and Chisel Method |
