The principle of straight-line access is discussed with particular reference to endodontic access of either maxillary or mandibular molar teeth. Modifications to the traditional triangular access opening are described that will make it easier for a p

The introduction of alternative electronic principles and circuitry has produced the next generation of electronic apex locators, which have fewer clinical limitations and greater ease of use, on a routine basis, than their predecessors. The history

The relationships between endodontics and periodontics are explored. Diagnosis, prognosis, and treatment planning are discussed for the primary endodontic lesion and the primary endodontic lesion with secondary periodontal involvement. These endodont

Secondary ion mass spectrometry (SIMS) has been used for the rapid, accurate analysis of B and Li in various nuclear materials. The problem of sample charging observed in the analysis of insulator materials has been overcome by distributing the sampl

Progress in the development of polycrystalline solar cells is hampered by the present poor state of knowledge about electronic and ionic processes at grain boundaries. A major difficulty in studying these processes is that conventional growth and the

In-situ formed oxide coatings have been proposed as hydrogen permeation barriers for candidate materials in heat exchangers and for hydrogen containment. In this regard oxides formed by oxidation of Incoloy 800 in 243 and 532 torr (1 torr = 133.3 Pa)

Q-switched lasers can serve as energy sources to replace conventional high-temperature furnaces in p-n junction formation in solar cells. They have been used to anneal ion-implantation damage, to produce laser-assisted dopant diffusion, and to regrow

We show that an extremely shallow (≲800 A) melt depth can be easily obtained by irradiating a thin (∼200 A) heavily doped silicon layer with a CO2 laser pulse. Since the absorption of the CO2 laser pulse is dominated by free‐carrier transitions
