Conventional wisdom advises that when a tooth needs to be extracted, the whole tooth should be removed, usually with as little surrounding bone as possible. However, the evidence to support this is not compelling, and every dentist has experienced cases where the apices of teeth are not removed for a variety of reasons and, in most cases, the patient seems to suffer no ill effects. If one extrapolates from this, it is evident that there might be instances where it is actually preferable to leave the apical part of the root rather than remove it, and this can be carried out deliberately. The usual time that one would consider this is when the inferior alveolar nerve is intimately related to the roots of the lower molar teeth, and this occurs most often in relation to the third molar. This concept of deliberately removing only the crown and part of the root of the tooth is known variously as coronectomy, partial root removal, deliberate vital root retention, or partial odontectomy.

ABSTRACT: Rational use of methane, the major portion of natural gas, has been the subject of investigation for many research groups throughout the world. Some studies have been devoted to the plasma-chemical conversion of methane-oxygen mixtures into methanol, however, the degree of conversion achieved was not over a few percent. At the same time, an increase in the degree of conversion is accompanied by a fast rise in the fraction of profound oxidation products carbon oxides. This course of events could be avoided if intermediate incomplete oxidation products could be removed from the reaction zone. It is known that radiolysis of gaseous hydrocarbons is accompanied, under certain conditions, by the formation of an aerosol consisting of condensing reaction products. This process can be used for removal the desired conversion products from the active zone of the reactor. The present study has been devoted to the conversion of light hydrocarbons mixed with oxygen in a plasma-chemical reactor where condensation of intermediate products stimulated by an electrical discharge has been accomplished

ABSTRACT: Removal of mandibular third molars is a common oral surgery procedure which is associated with a significant risk of injury to the inferior dental nerve (IDN). In an era of conservative dentistry the technique of coronectomy, which is conservative in terms of surgery and successful in minimising the incidence of IDN injury, has been met with some resistance and has been deemed non-ideal and controversial by many oral surgeons. This article outlines the benefits of coronectomy and highlights some examples from other dental specialities that have embraced conservative principles, despite their detractors.
