“…La caries dental es una condición crónica multifactorial que afecta el tejido calcificado de los dientes 9 , desmineralizándolo progresiva e intermitentemente. Tres factores influyen en su formación: la placa bacteriana (bajo acción de la bacteria acidogénica Streptococcus mutans), la dieta (rica en carbohidratos), y la propia propensión cariogénica del individuo (Houte, 1994;Legler & Menaker, 1980;Silverstone, Johnson, Hardie, & Williams, 1981). Se suele subestimar su rol en procesos infecciosos, aun cuando en sociedades preantibióticas pasadas una severa lesión cariogénica 8.…”

Marcadores biológicos considerados indicadores de estrés no específico se usaron para evaluar el estatus de salud y nutricional de dos asentamientos andinos del Horizonte Tardío (1430-1532 DC.) procedentes de la costa y sierra de Lima, Pueblo Viejo-Pucará y Huamanmarca respectivamente. Un total de nueve indicadores dentales y óseos fueron medidos: hipoplasia de esmalte (LEH), caries dental, desgaste oclusodental, sarro dental, hipercementosis, criba orbitalia, hiperostosis porótica, periostitis y trauma óseo. Los resultados sugieren que en ambas comunidades la propensión a padecer enfermedades vinculadas a los marcadores biológicos tales como periostitis, anemia o infecciosas fue baja, gozando gran parte de sus pobladores de un buen estado de salud. Sin embargo, en ambas poblaciones arqueológicas la diferencia en el porcentaje de casos afectados varió significativamente entre un sector residencial y otro, observándose una estrecha relación entre la frecuencia de un indicador de estrés óseo y dental, y (a) el estatus social, (b) el sector de procedencia, y (c) la actividad ocupacional de sus habitantes.

“…All carious lesions involve both demineralisation and remineralisation phases [4]. A lesion increases in size only when the calcium and phosphate ion exchange between the tooth and the saliva, mediated by bacterial plaque, favours net mineral loss over long time periods.…”

Restorative and scaling treatments have not generally provided an effective method for managing dental caries and periodontal diseases. Rather, restorative treatment has often covered up the disease processes in the short term and created a new problem: that of maintenance and re-restoration of restored teeth. Thus, standard invasive dental treatments that are commonly provided fail to address the fundamental bacterial nature of the diseases. Indeed, these treatments rather readily generate and perpetuate a totally unacceptable chain of events. This chain embraces many shortcomings, which themselves nurture what may be described as the repeat restorative cycle. The time has come to correct this iniquity. Dental caries and periodontal diseases are dynamic conditions which need ‘managing’ with a focused cocktail of preventive and refined restoration care. Much more emphasis should be placed upon the assessment of each and every caries or periodontal lesion, with a view to implementing specific preventive measures and allowing the natural arrest of disease processes to occur. The universal adoption of a preventive (evidence-based) approach to making dental treatment decisions could be by far the most powerful factor in reducing the restorative burden of dental services. It is clear that dental education and practice need to rise proactively to the challenge, or changes will be forced upon them while they are in a defensive position. There is a need to move wholeheartedly and contentedly into the preventive era.

“…In the case of a N-electron system, where this problem is best controlled, the only rigorous information about the electron density p ( r ) of the ground state which one encounters in the literature (Parr and Yang 1989, Kryachko and Ludefla 1989, Dreizler and Gross 1990 is its behaviour near the origin (Kato 1957, Steiner 1%3, Smith 1971 and at large distances (Morrell et 01 1975, Ahlrichs 1976, Hoffmann-Ostenhof e! 01 1978, Alhrichs ef a1 1981, Silverstone 1981). In addition, from a numerical point of view, one knows that the spherically-averaged electron density p ( r ) defined as is (i) monotonically decreasing from the origin (Sperber 1971, Weinstein ef al 1975, Simas ef 01 1988, Angulo 1989) for all ground-state neutral atoms, from hydrogen to uranium, (U) convex (Angulo ef a1 1990) for the atoms with Z = 1,2,7-15 and 33-44 while for the rest of the atoms up to Z = 54 it presenls a very small non-convex region.…”

Let us denole by p (r) the spherically averaged electron density of an atomic system. First, it is found that there always exbe a parameter mo 3 0 such that the function p(r)/r IS lo arithmically convex for any 01 2 00. Furthermore, 00 3 max{p,O) with to obtain rigorous and wmpact inequalities involving three radial expectation values, which substantially generalize all the similar ones known up to now. n e s e inequalities allow us lo correlate sweral fundamental andlor measurable physical quantities such as the nuclear elslron attraction energy, the Langmin-Pauli diamagnetic susceptibiliry and so on. Thirdly. the logconvexity properly is investigated in a Hanree-Fack framework for all ground-state neutral atoms with Z < 54. In parlicular, it is found that ail the atoms have a lagconvex function p(r)/r6 and only H and He have a logconvex electron density p (r). Finally, the accuracy of the abwe-mentioned inequalities is studied in the same numerical framework.
