Background and Objectives: There is evidence that melatonin could improve the periodontal status also glycemic control of patients with diabetes mellitus. Therefore, aim this study was to assess effects scaling root planing plus adjunctive systemic treatment on parameters in type 2 chronic periodontitis. Materials Methods: The conducted 54 subjects periodontitis mellitus randomly assigned group (n = 27, + melatonin) or placebo). Periodontal (probing depth—PD; clinical attachment loss—CAL;...
Type 1 diabetes is one of the most common chronic childhood diseases, which can be diagnosed at any age, with implications on general development, but also craniofacial structure. It widely speculated that occurs when inherited genetic characteristics are triggered by environmental factors. Oral pathology complex and it includes a series clinical entities: dental caries, periodontal disease, dento-maxillary anomalies, diseases oral mucosa, implies significant responsibility for doctor,...
Fixed orthodontic retainers can promote biofilm accumulation, increasing periodontal risks in patients with type 2 diabetes. This study examines the relationship between glycated hemoglobin (HbA1c) levels and bacterial load before after oral hygiene intervention. Forty diabetic (HbA1c: 6.5%-9%) were divided into Group I (18-30 years, n=18) II (>30 n=22). Periodontal samples analyzed using micro-IDent® PCR tests. Pearson's correlation linear regression assessed associations HbA1c load....
In this paper several aspects of profound modifications caused by high energy exposures are presented as possible candidates for the efficient adjusting processing polymer materials. The class hybrid composites receives special attention due to large spectrum formulations, where interphase interaction decisively influences material properties. They represent potential start points intimate uniformity morphologies. Their radiation turns onto morphology with expected features, because...
The purpose of this study was to assess the microbial composition and density subgingival plaque samples for periodontal pathogens while correlating values with glycemic control levels via glycated hemoglobin (HbA1c), a type that has chemically linked glucose, in I diabetes individuals who will undergo complex oral rehabilitation through orthodontic treatment implant surgery.
The aim of this study was to evaluate shear bond strength and adhesive remnant index between two different brands systems brackets. were represented by Opal Bond MV Composite Seal (Ultradent), respectively the fluoride releasing Transbond light cure paste XT (3M). utilised brackets Avex metal bracket system Unitek Miniature Twin Metal Brackets realized on 4 groups extracted teeth: first second using products manufacturer Ultradent, 3M, third fourth one other manufacturer. revealed that use...
According to titanium s much higher hardness and strength compared with the bone, if correctly applied, mini-screws will suffer no damage. Reusing orthodontic would reduce treatment cost lead more use of improvement treatments. In this study, scanning electron microscopy (SEM) was used assess structural variations retrieved implants evaluate mechanical properties that may adversely affect stability implants. For analisys 10 self-drilling mini-implants after treatment, made from commercially...
The present paper proposes a reliable alternative for the increasing stability of polypropylene (PP) by modified polyhedral oligomeric silsesquioxanes (POSS). chemiluminescence measurements and FTIR records point complementarily out determinant influence substituents on progress oxidation during accelerated degradation caused γ-irradiation. main kinetic approach acting in radiation-induced aging recommends some studied structures POSS as appropriate compounds improving at low additive...
This study assessed the impact of orthodontic fixed retainers on periodontal health in 40 patients with type 2 diabetes, divided into two age groups: 18-30 years (n = 18) and over 30 22). Bacterial loads were measured before after a 10-14 day oral hygiene regimen using micro-IDent test. In younger group, positive bacterial load decreased from 66.6% to 33.3% treatment, while older showed less improvement. Pathogens like Treponema denticola Prevotella intermedia more resistant especially...
This study examined the presence of periodontal pathogens in 29 patients with type 2 diabetes, categorized into three age groups: Group I (18–30 years), II (31–50 and III (51+ years). Porphyromonas gingivalis was detected various degrees across all groups, no significant correlation between pathogen patient age. The also highlighted prevalence Aggregatibacter actinomycetemcomitans, Bacteroides forsythus/Tannerella forsythia, Fuzobacterium nucleatum, which were present patients, indicating a...
The study of the mechanical behavior materials intended for dental restorations is crucial importance in production a finished product. In present work, two resins were used material matrix, Bisphenol A diglycidyl methacrylate (Bis-GMA), hydroxyethylmethacrylate (HEMA) and nanofiller (SiO2). This focuses on influence nanoparticle size (30, 50, 100 150 nm) properties (flexural strenght modulus, compression modulus work fracture) manufactured composite materials. results showed improvements...
The harmonious psycho-somatic development of the human body, implicitly sanogenesis dento-maxillary apparatus, is subject major concerns highlighted by numerous socio-economic actions and prophylactic curative medicine, planned directed. In this context, problems regarding etiopathogenic, clinical therapeutic particularities dento-alveolar disharmony through incongruity during growth period, are greatly actual, precisely because increasing frequency anomaly, especially due to...
The aim of this study is to characterize (wettability, surface roughness and gloss) test (microhardness diametral compression) four types light-cured composite resins, one which commercial. first lab-made the reference, obtained by mechanical mixing three monomers, in equal concentrations. following two materials can be considered nanocomposites because they were mechanically mixed base solution (Bis-GMA/TEGDMA/Bis-EMA) with α-Al2O3 nanopowders, a concentration 5 wt.% for 10 other. benchmark...
Background and Objectives: Corticotomy-facilitated orthodontics is an approach that can be useful in treating complex orthodontic cases could enhance the rate of tooth movement. The aim this study was to evaluate changes occurred buccal cortical bone at root level after treatment when corticotomy used, Romanian patients. Materials Methods: After dividing subjects into two groups (maxillary mandibular corticotomy), based on CBCT, measurements were made thickness cervical, median apical level,...
In this paper, the stability improvement of poly(lactic acid) (PLA)/styrene-isoprene block copolymer (SIS) loaded with silica nanoparticles is characterized. The protection efficiency in material thermal mainly studied by means high accurate isothermal and nonisothermal chemiluminescence procedures. oxidation induction times obtained CL determinations increase from 45 min to 312 as polymer free or filler loading about 10%, respectively. measurements reveal values onset temperatures 15% when...
The stability of polymer materials is essentially determined by the molecular structure and presence additives impurities. When a substrate subjected to vigorous damage an energetic treatment, scission generates fragments, which may be oxidized diffused oxygen. traces oxide catalysts that accidentally incorporated into initiate faster oxidation influences material durability. This study presents behavior poly (ε-caprolactone) (PCL) loaded with 2 wt% PbZrO3 previously doped foreign atoms (Cr,...
Amelogenine protein is the major component of continuously secreted enamel extracellular matrix that controls mineralization crystals. EmdogainTM an extract porcine fetal tooth material, a product based on high degree homology between and human proteins, composed primarily amelogenine protein. It was created to promote regeneration periodontal tissues such as cementum, ligament alveolar bone by stimulating normal development these tissues, it used treat deep intraosseus defects.
