Inevitably, the opinion 379 380 Forensic dentistry expressed in a forensic dental case is likely to lead to testimony. Tis chapter will guide the reader through the legal and court systems of the American justice system, explain the need for, and the use of, the expert witness in legal proceedings, and conclude with a review of several case law examples in which forensic dental testimony played an important role. First and foremost, it is an adversarial system in which opposing parties enjoy representation by attorneys who advocate for their client’s position. Te heart of the advocate’s representation is his or her duty to investigate fully the cir- cumstances and events surrounding the legal action coupled with the ability to subject the opposing side’s witnesses to a vigorous cross-examination, allowing the testimony of the witness to be thoroughly tested in front of the trier of fact—judge—or jury. A second principle is known as stare decisis, Latin for “to stand by that which is decided,” or the principle to adhere to prior precedential court decisions furthering the maxim “rule of law, not by man. Constitution estab- lishes the rights of citizens, which neither courts nor legislators can reduce or intrude upon. One can consider the division between criminal cases and civil cases, focus on the diferences between federal courts and state courts, or study the pro- cesses of the courts and how a legal case proceeds through the legal system. In a criminal case the govern- ment (commonly referred to as the State or the People) brings an action to impose sanctions for violations of the criminal code. Te prosecution team is usually led by an elected individual, ofen known as the district or state’s attorney, who is empowered through the ofce to pursue charges against individuals who have been arrested or cited for alleged violations of the law. Te prosecutor’s ofce and those who represent him or her in court are not duty bound to secure convictions but rather to present the state’s case fairly and demonstrate before the judge and jury that the accused has, by pre- sentation of evidence, performed the elements of the crime. For instance, in a homicide, ofen defned as the killing of one human being by another, the prosecutor may require testimony from many sources to prove who was killed, how that individual was killed, when the killing occurred, that the Jurisprudence and legal issues 381 accused had the opportunity to kill, and that the accused did in fact wield the instrumentality that resulted in death. Te prosecution must prove each of the elements to the trier of fact, in most cases a jury, beyond a reasonable doubt. While any dentist might be sued by a patient with an allegation of malpractice, forensic dentists are ofen involved in these types of cases as an expert witness for either the defense or plaintif. In order to prevail in a malpractice case, the plaintif must demonstrate by expert testimony that the defendant dentist performed substandard treatment, that is, rendered care that failed to equal or exceed the standard of care. Te defendant dentist’s attorney must counter the allegations by providing the testimony of a dentist stating that the care was at least equal to or exceeded the prevailing standard. A mere prepon- derance of the evidence, 50% plus a little bit, is all that is required for the prevailing side. Either side can appeal the verdict—a successful plaintif can complain that the damage award is insufcient, or an unsuccessful defendant dentist can argue the fnding of liability itself or complain to the appeals court that the damage award is too high. Most dental expert testimony will be given in cases that arise through state courts. A case arising and decided in one state system has no legal impact on how a similar case may be decided in any other state; however, there are similarities. Te district or trial court (local or regional) that enjoys original jurisdiction over civil and criminal cases that arise within a defned geographical boundary is the court in which the case is frst heard, with evidence and testimony being presented. Cases in these venues are usually argued in front of a jury, although a defen- dant or the parties can sometimes agree to forgo a jury and allow the judge to act as the trier of fact and rule on the law. In cases such as divorce and child custody, a jury trial is not allowed in most jurisdictions. Sitting in review of the decisions rendered at this frst level are the intermediate appellate courts, ofentimes known as the circuit court of appeal, although other names may 382 Forensic dentistry be used. Tese courts, comprised of multiple judges, hear the initial appeal sought by parties dissatisfed with decisions from the district courts. No testimony is heard in these courts; rather, an appointed panel of some of the appellate judges receives written arguments from each party citing the errors and mistakes that are alleged to have occurred in the original trial. Tis panel may request oral arguments from the attorneys, but testimony from witnesses is not heard. Te judges meet to discuss the case and render a written decision, which may uphold the original verdict, partially uphold the verdict, reverse the verdict, or order a new lower court trial in the case along with instructions to the district court on how or from whom testimony may be given. A party to the case at this level may, if desired, request that a larger panel of appeals judges rehear the case (ofen referred to as an en banc hearing), or may appeal the case to the fnal state court level—ofen known as the state supreme court. Similar to the original appeal, no testimony is heard, the justices receive only the written briefs (arguments) of the attorneys, and once again an oral argument may be scheduled. Afer discussion, the justices issue a written opinion on the case that constitutes the fnal state action. Te opinion may uphold the original verdict, partially uphold the verdict, reverse the verdict, or order a new trial in the case along with instructions to the district court on how or from whom testimony may be given. A party, as a fnal appeal, can request a rehearing by the state supreme court, an occurrence rarely granted. In some criminal cases, afer a defendant has exhausted his or her appeals in the state courts, he or she may appeal certain matters to the federal court system. Tese federal appeals can take years to conclude, as evidenced by some capital or death penalty cases. District Courts retain original jurisdiction for questions of federal law that arise within their respective district, of which there are currently ninety-four, including locations within the District of Columbia, Puerto Rico, and the territories of Guam, the Virgin Islands, and the Northern Mariana Islands. District Courts of Appeal, of which there are twelve, each usually encompassing all of the district courts in several states.

The temperature coefficient describes the influence of temperature on the effectiveness of chemical agents. The coefficient of temperature must be determined experimentally for each combination of antimicrobial agent and pathogen species. Mechanisms of Action When microorganisms are killed by heat, their proteins (enzymes) are irre- versibly denatured. This damage can be repaired to a certain extent Kayser, Medical Microbiology © 2005 Thieme All rights reserved. Most chemical agents (alcohols, phenols, alde- hydes, heavy metals, oxidants) denature proteins irreversibly. Physical Methods of Sterilization and Disinfection Heat The application of heat is a simple, cheap and effective method of killing pathogens. This is the antimicrobial treatment used for foods in li- quid form (milk): — Low-temperature pasteurization: 61. The guideline values for hot-air sterilizers are as follows: 180 8C for 30 minutes,160 8C for 120 minutes, whereby the objects to be sterilized must themselves reach these temperatures for the entire pre- scribed period. Autoclaves charged with saturated, pressurized steam are used for this purpose: — 121 8C, 15 minutes, one atmosphere of pressure (total: 202 kPa). In practical operation, the heating and equalibriating heatup and equalizing times must be added to these, i. When sterilizing liquids, a cooling time is also required to avoid boiling point retardation. In addition, the proteins of microorgan- isms are much more readily denatured in a moist environment than under dry conditions. Two types are used: — Gamma radiation consists of electromagnetic waves produced by nuclear disintegration (e. On a large scale, such systems are used only to sterilize bandages, suture material, plastic medical items, and heat-sensitive pharmaceuticals. The required dose depends on the level of product contamination (bioburden) and on how sensitive the contaminating microbes are to the radiation. Most of the available filters catch only bacteria and fungi, but with ultrafine filters viruses and even large molecules can be filtered out as well. These materials can be processed to produce thin filter layers with gauged and calibrated pore sizes. In conventional depth filters, liquids are put through a layer of fibrous material (e. The effectiveness of this type of filter is due largely to the principle of adsorption. Principles of Sterilization and Disinfection 39 Chemical Methods of Sterilization and Disinfection 1 Ethylene oxide. This highly reactive gas (C2H4O) is flammable, toxic, and a strong mucosal irritant. The gas has a high penetration capacity and can even get through some plastic foils. One drawback is that this gas cannot kill dried microorganisms and requires a relative humidity level of 40– 90% in the sterilizing chamber. Ethylene oxide goes into solution in plastics, rubber, and similar materials, therefore sterilized items must be allowed to stand for a longer period to ensure complete desorption. Formaldehyde irritates mucosa; skin contact may result in inflammations or allergic eczemas. In the past, it was commonly used in gaseous form to disinfect the air inside rooms (5 g/m3). The types of alcohol used in disinfection are ethanol (80%), propanol (60%), and isopropanol (70%). Due to their rapid action and good skin penetration, the main areas of application of al- cohols are surgical and hygienic disinfection of the skin and hands. Today, phenol derivatives substituted with organic groups and/or halo- gens (alkylated, arylated, and halogenated phenols), are widely used. One common feature of phenolic substances is their weak performance against spores and viruses. They bind to organic materials to a moderate degree only, making them suitable for disinfection of excreted materials. Chlorine, iodine, and derivatives of these halogens are suitable for use as disinfectants. Chlorine and iodine show a generalized microbicidal ef- fect and also kill spores. Calcium hypochlorite (chlorinated lime) can be used in nonspecific disinfec- tion of excretions. Chloramines are organic chlorine compounds that split off chlorine in aqueous solutions. The most important iodine preparations arethe solutions of iodine and potassium iodide in alcohol (tinc- ture of iodine) used to disinfect skin and small wounds. While iodo- phores are less irritant to the skin than pure iodine, they are also less effective as germicides. This group includes ozone, hydrogenperoxide, potassium perman- ganate, and peracetic acid. These substances (also known as surface-active agents, tensides, or detergents) include anionic, cationic, amphoteric, and nonionic detergent compounds, of which the cationic and amphoteric types are the most effec- tive (Fig. They have no effect at all on tuberculosis bacteria (with the exception of amphotensides), spores, or nonencapsulated viruses.
