Background: Diastema is a space between teeth. The most often is maxillary midline diastema between upper central incisors. One of the main causes of diastema is enlarged upper lip frenulum attachment. The aim of the study was to assess frenulum attachment in patients with diastema and investigate if type of upper lip frenulum attachment has an impact on the width of diastema. Materials and methods: Upper lip frenulum attachment was assessed clinically in two groups of adult patients: study group with diastema and control group without diastema. Moreover the width of diastema was measured on plaster models of dentition. The results were statistically analysed. Results: In study material the most often was diastema in range more than 2 mm. There were statistically significant differences between study and control group in upper lip frenulum attachment (p < 0.05). Normal frenulum attachment (mucosal or gingival) was typical for group without diastema, but enlarged frenulum (papillary or papilla penetrating) was characteristic for diastema group. Type of frenulum had significant (p < 0.05) impact to the width of diastema. Small diastema (≤ 2 mm) more often coexisted with normal frenulum. Oversized frenulum was observed in the big diastema (> 2 mm). Conclusions: Patients with diastema have more often oversized upper lip frenulum attachment then patients without diastema. The most often type of frenulum in patients with diastema is papillary and papilla penetrating type. Type of upper lip frenulum attachment has an impact to the size of diastema.

Oceniono zdolność wytwarzania śluzu przez 32 szczepy Staphylococcus aureus і 32 szczepy Staphylococcus epidermidis wykorzystując metody: ocenę morfologii kolonii na podłożu z czerwienią Kongo (CRA), z zastosowaniem roztworu safraniny (CT) i z użyciem metody spektrofotometrycznej z zastosowaniem czerwienieni Kongo (SC). Nie wykazano istotnych różnic w ocenie wytwarzania śluzu przez S. aureus i S. epidermidis przy wykorzystaniu metody CT i SC (p > 0,05), w przeciwieństwie do metody CRA (p < 0,0004 i p < 0,00001).

In this article, slime production of Staphylococcus aureus and Staphylococcus epidermidis strains from infective skin lesions was evaluated by three different methods: Congo red agar method (CRA), Christensen tube method (CT) and spectrophotometric method (SC). All strains by CT method interpreted as negative (dark-claret or red colonies of the surface). 12 (37,5%) strains of S. aureus, 16 (50,0%) strains of S. epidermidis produced slime as shown by CT method, 6 (18,7%) strains of S. aureus, 8 ( 25,0%) strains of S. epidermidis by SC method. They also found a correlation of slime production by CT and SC method (p > 0,05).

Background: The aims of the study were as follows: (1) to examine the width of the dental arches of patients with maxillary midline diastema and compare it with control group; (2) to investigate the impact of the width of upper dental arch on the width of diastema. Materials and methods: Diagnostic orthodontic plaster models of 102 patients with permanent dentition were studied. Patients were divided into two groups: study group with diastema and control group without diastema. Patients with severe malocclusion, craniofacial diseases, hypodontia and microdontia and patients with periodontal disease were excluded. The transpalatal width of palate, premolar and molar arch widths in Pont’s points of upper and lower jaw were measured using digital calliper. The results were statistically analysed. Results: Analysis showed a significant correlation between presence of diastema and premolar and molar width of the dental arches for both upper and lower jaw. Studied widths were larger in patients with diastema compared to the group without diastema. Analysis of the transpalatal width showed statistically significant differences between the study group and the control group. Analysis of widths of diastema and transpalatal widths showed that there was not statistically significant correlation. Conclusions: Patients with diastema had increased in size in both the premolar and molar width of the dental arches. Increase the width affect to both upper and lower dental arch. Patients with diastema also were characterised by often occurrence of normal or increased of the transpalatal width but the width of the diastema did not correlate with the width of the palate.

Background: The aim of this study was to assess the size of upper incisors and canines in patients with gaps in the upper dental arch, especially medium gap between upper central incisors. Materials and methods: Diagnostic orthodontic models of 30 adult patients with full permanent dentition with diastema in the upper arch were studied. Patients with severe malocclusion, missing teeth and periodontal disease were excluded. Width-to-length (W/L) ratio of the clinical crown of the central, lateral incisors and canines for both sides was measured. Together 180 teeth were tested. The results were compared with the values indicated by Sterrett et al. Results: In all patients, the clinical crowns of central incisors were symmetrical. In most cases, a higher W/L ratio was found, which indicates that the clinical crowns of medial incisors were too broad in relation to the length. Lateral incisors: In most cases, the ratio was the same for the right and the left side; however, a few patients had asymmetry of lateral incisors. Most of the lateral incisors had higher W/L ratios, which means that the teeth were wider than they were long; some had reduced ratios and only in one case the ratio was proper. Canines were also asymmetrical, and none of the canine exhibited perfect proportions. The vast majority showed increased W/L ratio of the clinical crown. In several cases, the W/L ratio was decreased. Conclusions: Patients with gaps between the teeth have abnormal W/L ratio of the clinical crowns of the upper front teeth. The values were increased in the majority of cases, which indicates that the front teeth were wider than they were long in patients with gaps. Moreover, despite the disturbed W/L proportions, central incisors remained symmetrical. In contrast, lateral incisors and canines more often exhibited asymmetries.

Thirty three isolates of K. pneumoniae were studied. The strains were cultured from different clinical specimens received from patients hospitalised at a Neurosurgery Unit at the Dr Jurasz University Hospital in Bydgoszcz. Production of ESBL was assessed using double disk synergy test. The genomic DNA was extracted from the strains separated by PFGE after digesting with XbaI endonuclease. Production of ESBL was detected in 81.8% of K. pneumoniae isolates. Molecular typing results revealed a great genetic diversity among K. pneumoniae isolates. All repeated PFGE patterns were detected in 12 (36.3%) K. pneumoniae isolates.
