Guindo Santo and Quillay are fundamental for the honey production of Biobío and the Ñuble region in Chile. Furthermore, Guindo Santo only exists in this area of the world.

Three-dimensional point spread function estimation method for mid-wave infrared microscope imaging.

A three-dimensional point spread function experimental estimation method based on the system's focal plane array spatial local impulse response of a mid-wave infrared microscope is presented. The method uses several out-of-focus two-dimensional point spread function planes to achieve a single three-dimensional point spread function of the whole microscope's optical spreading, expanding the limits of infrared optical technology by one dimension. This technique includes stages of image acquisition, nonuniformity correction, filtering, and multi-planar reconstruction steps, and its effectiveness is demonstrated on biological sample image restoration by means of a multi-planar refocusing application.

Oral Manifestations of Wolf-Hirschhorn Syndrome: Genotype-Phenotype Correlation Analysis.

Background: Wolf-Hirschhorn syndrome (WHS) is a rare disease caused by deletion in the distal moiety of the short arm of chromosome 4. The objectives of this study were to report the most representative oral findings of WHS, relate them with other clinical characteristics of the disease, and establish possible phenotype-genotype correlation.

Methods: The study was conducted at 6 reference centers distributed throughout Spain during 2018-2019.

Multiplanar full-field blur correction method for infrared microscopy imaging.

We propose a 3D full-field focusing method for microscopic mid-wave infrared (MWIR) imagery. The method is based on the experimental estimation of a confined volumetric vision microscope point spread function. The technique employs our well-known constant-range-based nonuniformity correction algorithm as a preprocessing step and then an iteration in the -axis Fourier-based deconvolution.

Simultaneous digital super-resolution and nonuniformity correction for infrared imaging systems.

In this article, we present a novel algorithm to achieve simultaneous digital super-resolution and nonuniformity correction from a sequence of infrared images. We propose to use spatial regularization terms that exploit nonlocal means and the absence of spatial correlation between the scene and the nonuniformity noise sources. We derive an iterative optimization algorithm based on a gradient descent minimization strategy.

Panoramic radiomorphometry and vertebral fractures in Spanish postmenopausal women.

Objective: To evaluate the relationship between panoramic radiomorphometric indexes, and the presence of osteoporotic fractures in a Spanish postmenopausal women.

Methods: A sample of 120 women (60 with fragility spine fractures and 60 healthy), aged 55-70 years, with fragility spine fractures, were included in this cross-sectional study that was conducted from 2008 to 2011. All the women were referred to undergo a radiological spine examination, spinal densitometry and a panoramic radiograph for assessing osteoporosis using 3 radiomorphometric indexes: Panoramic Mandibular Index (PMI), Mental Index (MI) and Mandibular Cortical Index (MCI).

Osteoporosis, fragility fracture, and periodontal disease: a cross-sectional study in Spanish postmenopausal women.

Objective: Osteoporosis and periodontitis are common disorders that affect aging populations. It has been hypothesized that both conditions may be related. The aim of this study was to evaluate the relationship between osteoporosis and periodontitis using vertebral fragility fracture as a real marker of osteoporosis and periodontal clinical examination to define periodontitis.

Clinical indicators of periodontal disease in patients with coronary heart disease: a 10 years longitudinal study.

Objectives: There is evidence about a possible relationship existing between periodontal diseases and coronary heart disease. The aim of the present longitudinal study was to investigate the changes in periodontal evolution after etiological periodontal treatment, comparing a healthy control group with another having coronary heart disease.

Study Design: The study included initially 55 patients of which 44 finished it.

Diabetes mellitus, periapical inflammation and endodontic treatment outcome.

The possible connection between chronic oral inflammatory processes, such as apical periodontitis and periodontal disease (PD), and systemic health is one of the most interesting aspects faced by the medical and dental scientific community. Chronic apical periodontitis shares important characteristics with PD: 1) both are chronic infections of the oral cavity, 2) the Gram-negative anaerobic microbiota found in both diseases is comparable, and 3) in both infectious processes increased local levels of inflammatory mediators may have an impact on systemic levels. One of the systemic disorders linked to PD is diabetes mellitus (DM); is therefore plausible to assume that chronic apical periodontitis and endodontic treatment are also associated with DM.

Relationship between smoking and endodontic variables in hypertensive patients.

Introduction: The aim of this study was to investigate the relationship between smoking and the prevalence of apical periodontitis and root canal treatment in hypertensive patients.

Methods: In a cross-sectional study, the records of 100 hypertensive patients, 50 smokers and 50 nonsmokers, were examined. Periapical status of all teeth was assessed by using the periapical index score.

Periodontitis and osteoporosis: a systematic review.

Background: Osteoporosis and periodontitis are frequent disorders that affect aging populations. It has been hypothesized that both conditions may be related.

Objective: To determine whether dental osteoporosis is a local manifestation of systemic bone loss having similar etiology and risk factors, or whether it is an independent process depending primarily on factors that cause periodontitis.

Predecessors of the giant 1960 Chile earthquake.

It is commonly thought that the longer the time since last earthquake, the larger the next earthquake's slip will be. But this logical predictor of earthquake size, unsuccessful for large earthquakes on a strike-slip fault, fails also with the giant 1960 Chile earthquake of magnitude 9.5 (ref.

A combination of orthodontic, periodontal, and prosthodontic treatment in a case of advanced malocclusion.

Some of the most difficult problems to resolve in daily clinical practice are those where there is interaction of various pathogenic factors, with consequent complication of the therapeutic solutions. Combined treatments based on sound diagnosis of the case and appropriate decision making to organize the therapeutic procedures in sequence are the best way of dealing with such situations. This article describes the case of a woman who was pregnant at the beginning of the treatment and had active periodontitis and angle Class II molar malocclusion because of loss of maxillary and mandibular teeth.

Ultrastructure of the gingiva in cardiac patients treated with or without calcium channel blockers.

Objectives: In the last few years, several studies have suggested that periodontal diseases are related to the development of atherosclerosis and its complications. Our objective was to study the ultrastructural morphology of the gingiva from cardiac patients, some of whom were treated and some not with calcium channel blockers compared to a control group.

Material And Methods: Fifty-five patients were studied and grouped in the following way: (a) healthy group (HG) (n=12) healthy patients with at least two pockets between 3 and 5 mm; (b) cardiac group (CG) (n=12) patients with cardiac disease untreated with calcium channel blockers; (c) diltiazem group (DG) (n=13) cardiac patients treated with diltiazem; (d) nifedipine group (NG) (n=18) cardiac patients treated with nifedipine.

Oral manifestations and dental treatment in menopause.

Menopause is a physiological process typically occurring in the fifth decade of life in women, and involving permanent cessation of menstruation. Menopause is the consequence of hormonal changes that produce a series of general manifestations that have become increasingly important as a result of the increased female life expectancy in the industrialized world; indeed, such manifestations are observed throughout the last third of the female lifetime. However, oral symptoms are also found in addition to the more general manifestations of menopause (i.

The gingival inflammatory infiltrate in cardiac patients treated with calcium antagonists.

Objectives: To analyse the periodontal inflammatory infiltrates in patients with cardiac disease, some of these patients were treated with calcium antagonists (nifedipine and diltiazem) and some were not, to compare them with a healthy control group, and to evaluate the changes in the inflammatory infiltrate after periodontal treatment.

Material And Methods: A "healthy group" (HG, n=12), a "cardiac group" (CG, n=12) without treatment with calcium antagonists, a "nifedipine group" (NG, n=18) and a "diltiazem group" (DG, n=13) were analysed. Biopsies were taken from a zone 2-3 mm below the upper part of the interproximal papillae 12-13 and 33-32 before causal periodontal treatment and after 1 year.

Effect of cigarette smoking on periodontal status of healthy young adults.

Background: It has been shown that tobacco is a significant risk factor for periodontal disease; however, there have been few studies on young populations where problems of general health can be discounted. The purpose of this study was to examine the influence of tobacco consumption on the periodontal condition of a young, healthy population.

Methods: The study population consisted of 304 young Caucasian males (average age 19.

The influence of general health and socio-cultural variables on the periodontal condition of pregnant women.

Background: There has been speculation as to whether hormonal changes during pregnancy or pre-existing conditions of general, oral, and dental health and socio-cultural background have a greater impact on the development of periodontal disease during pregnancy.

Methods: This study evaluates the periodontal status of 130 pregnant women (plaque index, bleeding index, probing depth, and clinical attachment level) and its relationship to demographic (age, professional level, education, and urban or rural residence) and clinical variables (gestation period, previous pregnancy, health status, previous live births, previous periodontal maintenance). The hospital in which the study was conducted was selected during a prior pilot study.

One hundred and fourteen mentally retarded (MR) and non-mentally retarded (NMR) patients were divided into two groups and categorized according to the condition presented. Age, sex, and type of procedure performed were recorded for each patient. On the MR group 32% were over 17 years of age.

Evaluation of gingival and periodontal conditions following causal periodontal treatment in patients treated with nifedipine and diltiazem.

It is established that phenytoin, cyclosporin and some calcium antagonists produce gingival overgrowth, but it is not known how this condition may respond to causal periodontal treatment. In order to find out, a longitudinal study was carried out, over a year, comparing a group of patients who were given nifedipine (NG, n = 18) and another group who were given diltiazem (DG, n = 13) with 2 others: one comprised cardiopathic patients who took no calcium antagonists (CG, n = 12) and the other contained patients who were medically healthy, with moderate periodontitis (HG, n = 12). On their basal visit, they were examined and instructed in oral hygiene, and then given causal periodontal treatment, being seen again at 4 and 8 months, when hygiene instructions were reinforced.

[The current status in obtaining a license for the practice of dentistry in the European Union and the United States of America].

Present regulations on the issuance of dental licenses are very different between the United States of America and the European Community. Two different mechanisms attempt to arrive at the fairest possible solution: licenses controlled by either national and/or local examinations in the United States, and licensing by credentials in the European Community. Both are compared and discussed.
