The use of physiotherapy in the regeneration of periapical bone structures of the teeth, prepared to load the prosthetic.

The aim of this work was to investigate whether the use of magnetoledotherapy will accelerate the elimination of osteolytic lesions of the dental periapical area, and provide for prosthetic treatment. What impact on time of healing does the inflammatory change location, type of treatment or patient's age have? 69 patients underwent the examination. The problem of osteolytic lesions in the course of protracted or protracted acute dental periapical tissue inflammation was determined. Patients were divided into two research groups: group L - treated with magnetoledotherapy and group K - treated without the support of magnetoledotherapy. In the first group we applied the electromagnetic field, generated using the Viofor JPS Clinic apparatus. Our studies have confirmed the effectiveness of magnetoledotherapy in the accelerated decommissioning of the osteolytic lesion. This provides evidence of the appropriateness of this method in the treatment of protracted dental periapical tissue inflammation, in teeth qualified for prosthetic load. Magnetostimulation combined with LED energy is an adjunctive procedure, adopted in order to eliminate osteolytic inflammatory changes of dental periapical tissues. It can be used in all age groups with the same good result. After applying magnetoledotherapy, in the course of the dental periapical tissue repair process of tooth treated endodontically for the first time as well as reendodontically, no differences were found. This shows the opportunity of using magnetoledotherapy in all cases of protracted periapical tissue inflammation.

From ophthalmologist to dentist via radiology.

BACKGROUND: The aim of this paper was to analyze the causes of orbital cellulitis in connection with covert dental changes as well as to establish the role of radiological procedures in the final diagnosis and further treatment of such cases. MATERIAL/METHODS: Thirty-two patients, aged 25-56, 22 women and 10 men were diagnosed and treated between January 2007 and April 2011 at the Pomeranian Medical University in Szczecin. The patients were examined in the infirmary of the ophthalmological department due to unilateral blepharo-oedema, abrupt pain and vision disturbances; in 5 cases, body temperature increased up to 37.8°C was observed. Next, the patients underwent conventional X-ray examinations of the orbit to exclude any foreign bodies in the eyeball, as well as pantomographies to evaluate the dental status. Visible periapical or periodontal changes in dentition were analyzed with intraoral X-rays with the use of DIGORA System 2.1. Changes found in 3 patients on pantomograms and connected with iatrogenic procedures were further evaluated with CT (64 lines and 128 layers) in frontal, sagittal and axial projections. Orbital disorders were also diagnosed by an ophthalmologist and radiologist with Doppler ultrasound (US) examinations. A linear transducer of 7.5-10 MHz to observe the morphology and vascularity of the eyeball was applied. RESULTS: IATROGENIC TREATMENT WAS THE CAUSE OF SINUSITIS AND CELLULITIS IN THREE CASES: incorrectly implanted dental implant in one case, root of the 3(rd) molar pushed into the sinus in the second case, and communication between the maxillary alveolar process and the sinus after extraction in case of the third patient. Asymptomatic periapical osteolysis, periodontal disease or dead teeth were found in all cases. Diagnosis of orbital cellulitis of dental origin was determined on the basis of clinical, radiographic and ultrasound findings. Ophthalmologic and dental treatment was applied simultaneously. CONCLUSIONS: Co-operation between ophthalmologists, radiologists and dentists is necessary during the treatment of such orbital diseases.

The change of electric potentials in the oral cavity after application of extremely low frequency pulsed magnetic field.

Electric potentials occurring in the oral cavity deserve attention as they may cause various diseases and subjective feelings, which are very difficult to treat. The aim of this study was to evaluate the electric potentials within the oral cavity in patients with metal fillings and metal prosthetic restorations, after using a pulsed electromagnetic field. The study was carried out on 84 patients. The Viofor JPS Classic device was used in the treatment. It generates a pulsed electromagnetic field with low induction of the extremely low frequency (ELF) range. Average values of electric potentials in the preliminary test were about the same in both groups; they were 148.8 mV and 145.5 mV. After another appliance of ELF fields there was found a steady decline in the average value of electric potentials in the study group. This decrease was statistically highly significant, while mean values of electric potentials in the control group were characterized by a slightly upward tendency. The obtained statistically significant reduction of electric potentials in the oral cavity of patients having metal fillings and metal prosthetic restorations, after application of the Viofor JPS Classic device, implies a huge impact of ELF pulsed electromagnetic field on inhibition of electrochemical processes, as well as on inhibition of dental alloy corrosion. 

Effect of pathological tooth wear on the content of calcium, magnesium, zinc and phosphate in human dentin.

AIM: To compare the mineral content of the dentin of worn versus unworn teeth. MATERIAL AND METHODS: Coronal dentin samples were collected from twenty one premolar teeth extracted for prosthetic or periodontal indications, including 11 intact teeth and 10 teeth with a significant occlusal wear. Samples were placed in concentrated nitric acid and diluted 500 times for the analysis of calcium and magnesium content and 11 times for the analysis of zinc. Contents of calcium, magnesium and zinc ions were established by means of atomic absorption spectrometry in an oxygen acetylene flame. The content of phosphorus was established by means of spectrophotometry using a test basing on a reaction of colour phosphoric-molybdenic complex formation. Data normality was assessed with Shapiro-Wilk test. Student's t-test was used for all comparisons. RESULTS: A statistically significantly higher content of magnesium and a lower Ca/Mg ratio were found in worn teeth at the 5% level. The concentrations of the other minerals analysed were not significantly different between the worn and intact teeth at the 5% level. CONCLUSION: Higher magnesium content in the dentin of human worn teeth may constitute a defence reaction to dentin exposure.

Limited effect of low frequency magnetic fields on the concentrations of calcium, magnesium and fluoride in saliva.

AIM: To assess the influence of low frequency magnetic fields on the contents of calcium, magnesium and fluoride in saliva. SUBJECTS AND METHODS: Sixty two patients were subjected to magnetic stimulation with low frequency magnetic fields of mean induction 3 microT at the first intervention and 4 microT at the following fourteen ones. Saliva was sampled before magnetic stimulation and after the 5th, 10th and 15th interventions. The contents of calcium and magnesium ions were measured by means of atomic absorption spectrometry. The content of fluoride was determined using an ion-selective electrode. RESULTS: No statistically significant differences were found between the calcium concentrations before magnetic stimulation and after 5, 10 and 15 interventions. Statistically significant differences in the magnesium concentrations were observed only between 10th and 15th interventions. No statistically significant differences in fluoride concentrations were found. CONCLUSION: Low frequency magnetic fields have no or weak influences on the content of calcium, magnesium and fluoride in saliva.

Microscopic evaluation of the tooth-bond-composite interface. Images from SEM. Preliminary report.

INTRODUCTION: Systems that bond composite material to enamel are constantly modernized (application is simplified and the number of system components is reduced). The latest products are one-coat systems combining etchant, primer, and bond. Use of such systems is easier for the dentist and adds to patient's comfort. The aim of this work was to evaluate microscopically the composite material--bond-enamel interface in a tooth processed with an abrasive technique. MATERIAL AND METHODS: The material comprised premolar human teeth extracted for orthodontic reasons. Cavities reaching the enamel-dentin border were created on the buccal surface of the teeth with the dental-prosthetic micropreparator (MSP). A self-etching Adper Prompt L-Pop system was applied (separate use of etchant was unnecessary). Bond application was according to manufacturer's recommendations. The cavities were filled with Point composite material from Kerr. Tooth samples were placed in the chamber of JEOL JSM 5500 LV scanning electron microscope and images were obtained at 15 kV. Strong bonding at the composite material-bond interface was observed as evidenced by the melting of composite particles into the self-etching bonding system.

[The impact of treatment by extremely low frequency magnetic fields on the electropotentials in an oral cavity and some chemical elements content in saliva]. / Wplyw zabiegów magnetostymulacji na elektropotencjaly w jamie ustnej i zawartosc niektórych pierwiastków w slinie.

INTRODUCTION: Introducing new methods of treatment in dentistry cause various alloys to appear in oral cavities. These alloys present in the oral cavity may generate an electrolytic cell, while saliva serves as a fine electrolytic conductor. Hence, the electropotentials that occur may initiate different illnesses. MATERIAL AND METHODS: The study was conducted among 25 patients. All of them have undergone treatment with the Viofor JPS system. The electropotentials in the oral cavity have been checked, as saliva's pH and selected levels of chemical elements have been estimated. RESULTS: After having applied a series of treatments with the JPS system it was found that the electropotentials decreased, pH level of saliva increased, the content of copper in the non stimulated saliva fell, no alterations in the remaining elements before and after the treatments were observed.

PURPOSE: OzonyTron is one of the newest devices for the generation of ozone. The aim of this study was to assess the benefits of ozone in some pathologies. MATERIAL AND METHODS: Ozone therapy was used in 20 patients, including eight with lip herpes, five after dental surgery and chiseling of third molars, six with seborrheal inflammation of facial skin and one with mycosis of the toes. RESULTS: Treatment with OzonyTron is noninvasive and painless. The oxidative properties of ozone are exploited to combat microbial infection. Thus, the device is valuable primarily for its antiseptic action. Following ozone therapy, a very good effect was observed in each case.

[Content of fluoride and magnesium in permanent teeth of children and adolescents with constitutional delay of growth and development]. / Zawartosc fluorków i magnezu w zebach stalych u dzieci i mlodziezy z konstytucjonalnie wolnym przebiegiem wzrastania i rozwoju.

INTRODUCTION: The objective of this study was to determine the content of fluorides and magnesium in permanent teeth of children and adolescents with constitutional delay of growth and development (CDGD) and to correlate the findings with susceptibility to caries. MATERIAL AND METHODS: Our study group consisting of 20 patients with CDGD, aged 11 to 20 years, was compared with an age-matched control group of 20 normal subjects. Dentition status was assessed according to the average DMFs score. Acid biopsy of enamel on the labial surface of incisors was done to measure the content of calcium, magnesium, and fluorides. CDGD patients demonstrated a higher average DFs value and less permanent teeth than their normal counterparts. RESULTS: Microanalyses of enamel showed that the depth of the acid biopsy was similar in all subjects. The content of fluorides and magnesium in enamel was lower in patients with CDGD.

[Scanning electron microscopic examination of the shape and surface of enamel fissures prepared with the MSP air abrasion method of art-dent]. / Ocena w skaningowym mikroskopie elektronowym ksztaltu i struktury sciany bruzdy w zakresie szkliwa po zastosowaniu abrazji powietrznej MSP (firmy art-dent).

INTRODUCTION: The specific structure of enamel fissures of molar teeth requires pre-treatment before a sealant can be effectively applied. MATERIAL AND METHODS: The air abrasion technique is gaining acceptance for this purpose. This study was undertaken to examine the effect of air abrasion on the shape and surface of fissures at three levels (entry, middle part and fundus). RESULTS: Compressed air mixed with aluminum oxide particles resulted in enlargement of the fissure. Microretention sites in the form of pits and hollows were discovered at all levels studied.

[Content of fluoride, calcium and magnesium in superficial layer of enamel from teeth with vital and necrotic pulp]. / Porównanie zawartosci fluorków, wapnia i magnezu w powierzchniowej warstwie szkliwa zebów z zywa i martwa miazga.

This work was designed to determine the content of fluorides, calcium, and magnesium in the superficial layer of enamel of adult teeth. The study group consisted of 25 patients, aged 18 to 35 years, appearing for dental treatment. Two microsamples of the superficial layer of enamel were collected from each patient with the acid biopsy technique. Samples were obtained from pulpectomized teeth treated endodontically and from teeth with necrotic pulp qualifying for endodontic treatment. Control samples were obtained from homonymous, caries-free teeth with vital pulp. The results of biochemical tests in the study group were compared with control teeth.

Fluoride concentration in superficial enamel layers of permanent teeth in children residing in areas with different levels of environmental pollution with fluorine compounds.

The concentration of fluoride in superficial layers of enamel of permanent teeth was studied in 14-year-old children residing in Szczecin and Bialystok-two cities differing regarding the level of environmental fluorine pollution. It was found that higher environmental pollution with fluorine favors the accumulation of this element in superficial layers of enamel in the form of structural fluoride. Total and structural fluoride concentration decreased with layer depth.
