Opis:: The aim of this study was to estimate the influence of liming effect on leachability of heavy metals from sewage sludge. Samples were taken from the Wastewater Treatment Plant in Strzelce Opolskie. The research material were sewage sludge collected before and after liming process. Dry matter, pH, heavy metals content and their forms were analysed in sludge samples. It was found that the studied sewage sludge can be used for agricultural purposes, because the heavy metal content does not exceed the limit values. The average content of metals in limed sewage sludge was slightly lower than in the raw ones, except for cadmium. Leaching of heavy metals from sewage sludge samples was depended on the ionic strength of the extractant. It was found that liming of the sludge did not affected the reduction of leaching of metals.
Celem pracy było określenie wpływu wapnowania osadów ściekowych na wymywalność metali ciężkich. Próbki do badań pobrano z Oczyszczalni Ścieków w Strzelcach Opolskich. Materiał badawczy stanowiły osady ściekowe przed i po procesie wapnowania. W próbkach osadów oznaczono zawartość suchej masy, odczyn pH, zawartość metali ciężkich oraz ich form chemicznych. Stwierdzono, że badane osady mogą być wykorzystane rolniczo, gdyż udział metali ciężkich nie przekroczył dopuszczalnych norm. Średni udział metali w osadach wapnowanych był nieco niższy niż w osadach surowych, za wyjątkiem kadmu. Wymywalność metali ciężkich zależała od siły jonowej zastosowanego ekstrahentu. Stwierdzono, że wapnowanie osadów ściekowych nie zmniejszyło wymywalności metali.

Opis:: W prezentowanych badaniach użyto nanocząstek hydroksyapatytu (nanoHAP) do przygotowania nanowłóknistego kompozytu poli-L-kwasu mlekowego/hydroksyapatytu za pomocą elektroprzędzenia. Zbadano średni rozmiar i strukturę nanoHAP, średnią średnicę nanowłókien i ich strukturę. Dodatkowo, zbadano skład chemiczny wszystkich przygotowanych materiałów. Wytworzono nanowłókna PLLA/nanoHAP o średniej średnicy włókna 202 ± 6 nm z jednorodnie rozproszonymi cząstkami nanoHAP w strukturze włóknistej.
In present study, nanoparticles of hydroxyapatite (nanoHAP) were used to prepare nanofibrous composite of poly-L-lactic acid/hydroxyapatite by electrospinning. An average size and structure of nanoHAP, nanofibers average diameter and structure of nanofibrous materials were investigated. Additionally, the chemical composition of all materials was investigated. Nanofibers of PLLA/nanoHAP having the average diameter of 202 ± 6 nm with uniformly dispersed nanoHAP in the fibrous structure were produced.

Opis:: Introduction. There are reports in literature which indicate the connection between impacted third molars and occurrence of symptoms of craniomandibular dysfunctions and headaches. Objectives. The aim of this study was evaluation of the outcome of patients who reported specific symptoms of craniomandibular dysfunction and had impacted mandibular third molars. Materials and method. The research material consisted of 10 women who reported to the Department of Craniomandibular Disfunctions of the Medical University in Lublin, Poland, with pain and acoustic symptoms in the Temporomandibular joint (TMJ) area. During preliminary therapy, the patients used a silicone occlusal device; ionotherapy was ordered and the patients were recommended to eliminate parafunctions. Results. Clicks before treatments were present in 6 patients, after treatment with silicone occlusal device and ionotherapy with Profenid gel in 5 patients, while two years after extraction of the impacted teeth the clicks were no longer present, and differences in the presence of clicks analyses by means of the Q-Cochran test were statistically significant between examinations 1m vs.3 (Q=10.33; p<0.01) and examinations 2 vs.3 (Q=8.40; p<0.05). Conclusions. The study showed that extraction of the mandibular third molars can cause regression of some symptoms of craniomandibular disorders.

Opis:: Introduction and objective. A hectic lifestyle and everyday stress are direct causes of parafunctions. The objective of the presented study was to examine the relation of sleep disorders, distant pain symptoms, symptoms of pathological tooth wear in rural and urban patients with parafunctions. Materials and methods. The patient group consisted of 836 women and 274 men aged 9-82, and divided into groups taking into account the following criteria: number of patients in certain age groups, number of women and men, place of residence, presence of missing teeth problem, presence of occlusal and non-occlusal parafunctions, symptoms of tooth wear, distant pain symptoms, and sleep disorders. Results. 354 (31.89%) of the patients came from the rural environment. Distant pain symptoms were more frequent in patients performing parafunctions than in those who did not perform parafunctions (n = 1110, RR = 1.10, CI = from 1.04 to 1.16). Sleep disorders were more frequent in patients performing parafunctions than in those who do not perform parafunctions (n = 1110, RR = 1.06, CI = from 1.00 to 1.12). Symptoms of pathological tooth wear were more frequent in patients performing parafunctions than in those who did not perform parafunctions (n = 1110, RR = 1.08, CI = from 1.02 to 1.13). Conclusions. It is extremely important (as it is international problem) to introduce prophylactic care to prevent the occurrence of parafunctional activity in patients from the rural environment. Parafunctions, therefore, should be taken into account in the diagnosing procedure of such disorders and pathological symptoms as pathological tooth wear, sleep disorders, cervicalgia, neck myalgia, shoulder girdle myalgia, and dorsalgia.

Opis:: Hygiene plays an important role in patients who use removable dentures. The proper way of cleaning and storage also provides better health of oral cavity tissues as well as for the remaining teeth. The research involved 162 patients, 133 women and 29 men, aged 60–90, with different levels of education, the majority with secondary education. All patients were using removable dentures. 85.8% declared earlier use of dentures, and a half of the patients had used dentures for no more than 7.5 years. A considerable percentage (33.95%) used dentures for the whole day. Storing in a container with fluid was used by 25.93% of the respondents. Over 70% used toothpaste to clean their dentures and about 14% immersed them in special preparations, e.g. CoregaTabs, while over 8% used soap. Among patients who cleaned their dentures, the majority cleaned them once a week (75%) and the minority – twice a week (25%). The greatest percentage of patients cleaned their dentures with a toothbrush and toothpaste, which is not recommended due to occurring microabrasions. It is recommended that patients should be educated regarding prosthesis hygiene and regular follow-ups.
