Periodontal Disease in Patient with Type 2 Diabetes Mellitus

Type 2 diabetes is one of the most important growing health problems worldwide causing several complications in different parts of the organism, including the oral cavity. Aim: The purpose of this study is to assess the periodontal disease of type 2 diabetes patients which came randomly and voluntarily for evaluation of their oral health. Materials and methods: 112 patients with marginal inflammatory pathology were selected and evaluated. The followed parameters were: age, gender, environment, status of diabetes, oral non-odontogenic lesions, local aspects of marginal tissue inflammation. Data were centralized in electronic format using Microsoft Excel software. Results: The average age of patients was 57.3, 56.25% of all patients had uncompensated diabetes with HbA1c levels over 7.5%. Most of them were males (52%) and lived in an urban community (83.93%). 52.27% had severe forms of periodontitis, requiring radical treatment, while the most common oral non-odontogenic pathology was candidosis (40.98%). Conclusion: By modifying local metabolism, diabetes increases the risk of inflammatory lesions, especially periodontitis

Treatment Options of Periodontal Disease and its Complications in Patient with Type 2 Diabetes Mellitus

Diabetes mellitus type 2 is the most commonly diagnosed metabolic disorder, and its prevalence is expected to increase so much, that by 2030 approximately 10% of the population will have diabetes (especially type 2). The aim of this study: is to assess the treatment methods used for oral odontogenic infections in patients with type 2 diabetes, as well as postoperative complications depending on the applied treatment method. Materials and methods: a group of 112 patients with marginal inflammatory pathology was selected and evaluated. The followed parameters were: age, gender, inflammatory lesions, treatment type, one week, three and six months postoperative evolution. Data were centralized in electronic format using Microsoft Excel software. Results: The average age of patients was 57.3, and gender distribution was almost equal (51.78% males vs. 48.21% females). The majority of patients (47.32%) underwent a conservative treatment, while almost 68% had a very good postoperative healing at the 7 day postoperative recall. There was also a significant improvement of the values of glycated hemoglobin at both the three and the six months recall, with almost 2/3 of the patients presenting a normal gingival status. Conclusion : Periodontal disease has a negatively impact on diabetes control, and can worsen its complications, but periodical periodontal treatment improves glycemic status, the latter contributing further to better oral status and lower the incidence of complications

Ground state hyperfine structures of 43K and 44K measured by atomic beam magnetic resonance coupled with laser optical pumping

The ground state hyperfine structures of 43 K and 44K have been measured by an atomic beam magnetic resonance method in which the atoms are spin-polarized by laser optical pumping. The spectroscopic results are : Δv43( 2S1/2) = 192.648 4 (30) MHz and Δν44( 2S1/2) = - 946.718 (3) MHz. The sensitivity of our method is compared to the one achieved in classical ABMR apparatus

Stabilization and pumping of giant vortices in dilute Bose-Einstein condensates

Recently, it was shown that giant vortices with arbitrarily large quantum numbers can possibly be created in dilute Bose-Einstein condensates by cyclically pumping vorticity into the condensate. However, multiply quantized vortices are typically dynamically unstable in harmonically trapped nonrotated condensates, which poses a serious challenge to the vortex pump procedure. In this theoretical study, we investigate how the giant vortices can be stabilized by the application of a Gaussian potential peak along the vortex core. We find that achieving dynamical stability is feasible up to high quantum numbers. To demonstrate the efficiency of the stabilization method, we simulate the adiabatic creation of an unsplit 20-quantum vortex with the vortex pump.Comment: 8 pages, 6 figures; to be published in J.

Proposal for new experimental schemes to realize the Avogadro constant

We propose two experimental schemes to determine and so to realize the Avogadro constant $N\_{A}$ at the level of 10$^{-7}$ or better with a watt balance experiment and a cold atom experiment measuring $h/m(X)$ (where $h$ is the Planck constant and $m(X)$ the mass of the atom $X$). We give some prospects about achievable uncertainties and we discuss the opportunity to test the existence of possible unknown correction factors for the Josephson effect and quantum Hall effect

Atomic transition frequencies, isotope shifts, and sensitivity to variation of the fine structure constant for studies of quasar absorption spectra

Theories unifying gravity with other interactions suggest spatial and temporal variation of fundamental "constants" in the Universe. A change in the fine structure constant, alpha, could be detected via shifts in the frequencies of atomic transitions in quasar absorption systems. Recent studies using 140 absorption systems from the Keck telescope and 153 from the Very Large Telescope, suggest that alpha varies spatially. That is, in one direction on the sky alpha seems to have been smaller at the time of absorption, while in the opposite direction it seems to have been larger. To continue this study we need accurate laboratory measurements of atomic transition frequencies. The aim of this paper is to provide a compilation of transitions of importance to the search for alpha variation. They are E1 transitions to the ground state in several different atoms and ions, with wavelengths ranging from around 900 - 6000 A, and require an accuracy of better than 10^{-4} A. We discuss isotope shift measurements that are needed in order to resolve systematic effects in the study. The coefficients of sensitivity to alpha-variation (q) are also presented.Comment: Includes updated version of the "alpha line" lis

Polarimetric interferometer for nanoscale positioning applications

International audienceWe propose and demonstrate a displacement control method at the subnanometric scale based on a Michelson interferometer combined with a polarimeter and a phase-locked loop electronic board. Step by step displacements with a step value of 5 nm are presented. A repeatability of 0.47 nm is obtained from back and forth displacements over 1 m range. We show that a residual ellipticity of less than 10° on the polarization state leads to a positioning error of less than 1 nm. Such system could be used over millimeter range displacements in a controlled surrounding environment leading to numerous applications in nanometrology

Midfacial fractures: A retrospective etiological study over a 10-year period in Western Romanian population

Introduction: Midfacial fractures are extremely important oral and maxillofacial problems because they take varied forms and are frequently accompanied by major long‑term esthetic or functional complications. Their etiology and epidemiology vary significantly in the literature, and the main causes are varied by population. The aim of this study is to identify the main traumatic etiology of midfacial fractures, along with the main categories of affected patients in our geographical area, in order to establish the need for measures that can prevent fractures in the future.Materials and Methods: We conducted a retrospective study over a 10‑year period in 379 patients. Data were extracted from the patients’ charts, and the following variables were taken into consideration: sex, age, environment of origin, education level, and traumatic etiology.Results: Midfacial fractures most frequently affected the 20–29 years age group (31.93%), male sex (n = 333, 87.86%, M:F = 7.23:1), patients from urban areas (n = 206, 54.35%), and patients without education (46.70%). The most frequent etiology was interpersonal violence (44.85%), followed by fall trauma (16.62%) and road traffic accidents (15.30%). Statistical correlations evidenced that urban environment favors midfacial fractures caused by interpersonal violence and road traffic accidents or sports injuries, while in rural areas, domestic accidents and animal attacks are predominant (P = 0.000).Conclusions: The overwhelming incidence of interpersonal violence in our population is currently a major public health problem. Implementing laws and initiating national programs for the prevention of interpersonal violence would lead to a considerable reduction of midfacial fractures in the Western Romanian population.Keywords: Etiology, fracture, interpersonal violence, midface, traum
