New ways of combating demineralization: link between classic and allopathic medicine
No full textPrevention and allopathic medicine gained attention, since it is possible for dentists to prevent demineralization, using plants and natural substances with well-known efficacy. The purpose of this study was to present new methods for teeth remineralization. It was made a selection of 10 extracted teeth, maintained in physiological serum, with no color fading, decay or demineralization. It was induced demineralization, with ortho-phosphoric acid (concentration 45 %), for one minute. The probes were visually and with optical coherence tomography (OCT) inspected. The natural product and the bonding with additional nanoparticles of argent were created and applied on the demineralization zone of the both groups of teeth. Each tooth in the first group had one plain surface demineralized. The second group of teeth had a cavity prepared on one of each tooth’s side. The pastes were applied on the demineralized surfaces and in the demineralized cavities for two minutes. After time expired, the pasta applied on the first group of teeth was washed away; the bonding above the second group of teeth was light cured. The probes were again visually and with OCT inspected. It was observed an improvement in remineralizing the white marks on plain surfaces and in the created cavities, the OCT being able to detect different levels of remineralization. The efficacy of natural pasta depends on the time it is applied and the concentration of the different main substances. Also, the type of surface, plain or occlusal facets, may influence the substances’ penetration ability. The non-invasive specific feature of these products, low costs and safety are strong positive aspects of this method of remineralization. However, the natural process of remineralization is a long-lasting one; perfecting the main substances in order to accelerate the process, in addition to several in vivo studies would be necessary to be fulfilled
Characterisation of drug and placebo effects on water by NIR and Opto – magnetic spectroscopy
No full textIn conventional medicine, homeopathy has always aroused a great deal of skepticism, just as a placebo effect. In homeopathy, substances are diluted way beyond the point at which no trace of the original substances could remain and could be detected. It is as though the water has retained memory of the departed molecules.
In the recent years, as the technology and science has progressed, some new extraordinary findings about water has emerged: that it forms massive exclusion zones of highly structured water [2], that it is quantum coherent [3], and that it can be used as a mirror to explore what is dissolved in it [4].
Furthermore HIV discoverer and Nobel Prize winner Luc Montagnier has given support to Benveniste’s findings [4] and published results of his experiments in which the DNA sequence was recreated from its electromagnetic signature in pure water [5].
Giving this new evidences in support of existing memory of water, we performed a study on placebo effect and homeopathic solutions using novel methods of Opto-magnetic spectroscopy [6], which studies water electromagnetic and magnetic properties, and NIR spectroscopy with the new approach Aquaphotomics to explore the water structure [4].
Our preliminary findings are in support of existence of water memory

We present a very rare case of herpes zoster involving S1 dermatome in a 35-year-old healthy man who presented aching pain and typical herpes zoster eruption on the lateral aspect of the calcaneus, lateral plantar area and dorsal aspect of digits III and IV.Keywords: herpes zoster, S1, pain, sacral zoste
Dental Impression Technique Using Optoelectronic Devices
No full textThe use of Optical Coherence Tomography (OCT) as a non-invasive and high precision quantitative information providing tool has been well established by researches within the last decade. The marginal discrepancy values can be scrutinized in optical biopsy made in three dimensional (3D) micro millimetre scale and reveal detailed qualitative and quantitative information of soft and hard tissues. OCT-based high resolution 3D images can provide a significant impact on finding recurrent caries, restorative failure, analysing the precision of crown preparation, and prosthetic elements marginal adaptation error with the gingiva and dental hard tissues. During the CAD/CAM process of prosthodontic restorations, the circumvent of any error is important for the practitioner and the technician to reduce waste of time and material. Additionally, OCT images help to achieve a new or semi-skilled practitioner to analyse their crown preparation works and help to develop their skills faster than in a conventional way. The aim of this study is to highlight the advantages of OCT in high precision prosthodontic restorations
Superficial basal cell carcinoma treated with 70% trichloroacetic acid applied topically: a case study

The treatment concept for BCCs is the surgical one, but it is costly, as such, searching for alternative medical therapeutics is justified. Aim: To highlight the efficacy of high concentration (70%) trichloroacetic acid (TCA) as a choice therapy for low-risk BCC. Method and patient: Authors present, for the first time, the use of a high concentration TCA applied once a week for 2 consecutive weeks with a toothpick, on a patient with BCC on the right preauricular area. Results: On examination 4 weeks later, the lesion was not clinically and dermatoscopically evidenced. Conclusion: High concentration TCA could be an effective and safe, non-invasive choice of therapy for low-risk BCC, easy to perform, not expensive, with good cosmetic results, especially for patients who are not likely to undergo invasive or expensive treatments. Keywords: basal cell carcinoma, therapy, trichloroacetic acid, dermatolog
Nail Damage (Severe Onychodystrophy) Induced by Acrylate Glue: Scanning Electron Microscopy and Energy Dispersive X-Ray Investigations
No full textScanning electron microscopy (SEM) and energy dispersive X-ray (EDX) techniques have been used in various fields of medical research, including different pathologies of the nails; however, no studies have focused on obtaining high-resolution microscopic images and elemental analysis of disorders caused by synthetic nails and acrylic adhesives.
METHODS:
Damaged/injured fingernails caused by the use of acrylate glue and synthetic nails were investigated using SEM and EDX methods.
RESULTS:
SEM and EDX proved that synthetic nails, acrylic glue, and nails damaged by contact with acrylate glue have a different morphology and different composition compared to healthy human nails.
CONCLUSIONS:
SEM and EDX analysis can give useful information about the aspects of topography (surface sample), morphology (shape and size), hardness or reflectivity, and the elemental composition of nail
Alopecia Areata and Suicide Ideation
No full textAlopecia areata represents an autoimmune process against an unidentified autoantigen in the follicle of the hair, which affects all ages, from young children (a few months old) to elderly patients. Alopecia areata has an important impact on the quality of life, leading to a predisposition towards anxiety and depression, especially if the patients are treated with corticoid therapy that heightens the risk for such psychiatric disorders. We present the case of a patient with alopecia areata who was diagnosed at the age of 18 months, and had been followed-up until the age of 27 years
