To investigate the subgingival microbiological profiles of patients with periodontitis, to determine their stage and grade scores and to evaluate the differences in the microbiota among different stages and grades. Materials and Methods Sixty-seven (n = 67) periodontitis patients were selected. Periodontitis staging and grading, following the 2018 classification system, were defined. Following a clinical examination, subgingival samples were taken from the deepest periodontal pocket of each quadrant for cultivation, identification and quantification. The prevalence, proportion and counts of nine selected periodontal pathogens were determined, and differences between periodontitis stages III and IV and grades B and C were assessed. Results All nine cultivable periodontal bacteria were detected, of which the most prevalent was P. intermedia (91.0%) and the least prevalent were E. corrodens (9.0%) and C. ochracea (9.0%). The frequency of detection of the two main target pathogens, A. actinomycetemcomitans and itis patients, whereas the counts of P. gingivalis and A. actinomycetemcomitans were similar between grades and stages. Conclusion Our study suggests that relevant differences between the various grades of periodontitis exist only in the numbers of F. nucleatum. Prevalence and quantities of other cultivable species between different stages and grades of periodontitis seem to be similar.<br /><br /> The aim of the present research was to analyse the effects of two bleaching agents, on the enamel crystallography by means of X-ray diffraction.<br /><br /> Twelve human sound posterior teeth, were collected for the present study (n = 12) and from each tooth two enamel slabs were obtained and randomly assigned to one of two different bleaching protocols. The first protocol involved an in-office bleaching agent (hydrogen peroxide 37.5%/ SDI Polaoffice+), and the second an at-home whitening product (carbamide peroxide 16%/ PHILIPS Zoom! NiteWhite). X-ray diffraction readings were made before and after applying the treatments in order to analyse the peak intensity and crystal domain size. Additionally, scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) were carried out to identify the composition correctly. Statistical analysis included repeated measures analysis of variance (p ≤ 0.05). Results Peak intensity in spectra obtained by X-ray diffraction had a tendency to diminish, mostly in thy-dispersive X-ray spectroscopy (EDX) were carried out to identify the composition correctly. Statistical analysis included repeated measures analysis of variance (p ≤ 0.05). Results Peak intensity in spectra obtained by X-ray diffraction had a tendency to diminish, mostly in the at-home bleaching group. The analysed data approximate a decrease in the crystal domain size among the samples treated for longer periods of time. Statistical analysis depicted no statistically significant differences among the experimental groups (p ≥ 0.05). Conclusions Crystal domain size had a tendency to decrease, mostly when the enamel was treated by bleaching gels that had to be applied by prolonged periods of time.<br /><br /> Purpose To assess the association of various factors including education level and oral health with type 2 diabetics' awareness of periodontitis and periodontitis/diabetes relationship, and to evaluate the importance of integrated healthcare in this association. Materials and Methods 288 type 2 diabetics were evaluated through a validated structured questionnaire about oral hygiene habits, access and attendance to dental treatment, the presence of periodontitis and previously received information of periodontitis and periodontitis/diabetes relationship. Descriptive data were explored and both simple and multiple logistic regressions were performed. Results The average age of participants was 62.24 (±10.93) years, 81.6% were previously treated for periodontitis and approximately 70% have never received information on periodontitis and its relationship with diabetes. A higher chance of participants having previously received information regarding periodontitis was associated with more than 8 years of schoolinally significant associations were observed for more than 12 years of schooling and diabetes diagnosed more than 8 years ago (p  less then  0.05). Conclusion The vast majority of participants were previously treated for periodontitis without receiving proper oral health education, which means that access to costly dental treatment is provided while patient education is neglected. It was shown the influence of habits and living conditions on the previously received information about diseases, and therefore, particular attention to the population characteristics is important to make the information accessible to everyone.......Ideally, orthognathic surgery is indicated to treat skeletal Class III malocclusion with severe open bite in adults. In this borderline case, however, camouflage treatment without any skeletal anchorage was chosen. This report describes the orthodontic treatment of a 23-year-old man who presented with multiple orthodontic problems including severe open bite of the anterior and posterior teeth up to the first molars, bilateral posterior crossbite, bilateral Class III molar relationship, severe crowding, increased vertical dimension, and dental and facial midline deviation. The treatment included the extraction of four wisdom teeth, uprighting and distalisation of the mandibular arch with molar intrusion using curved NiTi wires with intermaxillary elastics. After 36 months of treatment, satisfactory improvements in the vertical overlap, horizontal overlap and sagittal malocclusion were achieved. The design of the mechanical system used in this case confirmed stable results at the 4-year follow-up.Objective To evaluate and analyse granulomatous reaction caused by intradermal injections with hyaluronic acid (HA) fillers in the orofacial region. Methods A retrospective review of 11 cases of foreign body granulomas caused by HA fillers was performed. Demographic data, clinical symptoms, imaging features, treatments, pathology results, history of facial cosmetic procedures and prognosis were reviewed. [https://www.selleckchem.com/products/cerdulatinib-prt062070-prt2070.html PRT062070] Results Most of the cases appeared as painless palpable nodules with no significant growth, located in the cheeks, chin, lips or temples. The nodules were excised, and pathological examination revealed amorphous basophilic material surrounded by foreign body giant cells and macrophages. No patient’s clinical and pathological diagnosis was linked to HA during the first appointment. During follow-up, all patients admitted that they had received dermal filler injections from 3 to 10 years previously. Most of the patients had a favourable prognosis; one patient complained of facial asymmetry and another reported mild pain in the upper lip after surgery.
