Abstract Background Conventional brackets are often used during orthodontic therapy patients with malocclusion. Nevertheless, their complicated construction greatly inhibits oral hygiene, which predisposes to the increased carriage of the microbiota. It seems that orthodontic brackets could be a reservoir of yeast and predisposing to develop oral candidosis. Objectives The aim of this study was to assess changes in Candida species prevalence and periodontal parameters after orthodontic brackets placement in patients who received oral hygiene instruction; to determine role of elastic ligatures in those changes; to characterize isolated yeasts according to their ability to biofilm formation. Patients/Methods 17 participants (average age 17±7 years) have been monitored by taking oral rinses, elastomeric ligatures samples and evaluation of API and GBI Indexes before and after placement of orthodontic conventional brackets for 12 weeks. Isolated yeasts was counted and used to the biofilm formation assay. Results 116 samples (67 oral rinses and 49 orthodontic elastomers) were collected. 51% of patients were carriers of Candida in which C. albicans was the most common species. The average number of colonies (CFU/ml) obtained from oral rinses showed an upward trend depending on duration of the study and some correlation with periodontal indexes (API, GBI) was found. One third of the analysed strains have shown ability to form greater biofilm than control strain. Conclusions Orthodontic ligatures surface permit biofilms creation and orthodontic brackets change dynamic oral microbiota. Maintaining proper oral hygiene is crucial for every orthodontic patient.

Abstract Background: Conventional brackets are often used during orthodontic therapy of patients with malocclusion. T heir complicated construction greatly inhibits oral hygiene, which predisposes to increased carriage of microbiota. Orthodontic brackets could be a reservoir of yeast and predispose to oral candidosis.Objectives: The aim of this study was to assess Candida prevalence and role of oral hygiene during fixed appliance therapy. Further aim was to characterize isolated yeasts according to their ability to biofilm formation.Methods: Seventeen participants (average age 17 ± 7 years) were monitored by taking oral rinses, elastomeric ligatures samples and evaluation of Approximal Plaque Index (API) and Gingival Bleeding Index (GBI) before and after placement of orthodontic conventional brackets for 12 weeks. Isolated yeasts w ere counted and biofilm formation was evaluated.Results: One hundred and sixteen samples (67 oral rinses and 49 orthodontic elastomers) were collected. Ten patients (58.8% subjects) were Candida-carriers (2 were colonized after bracket placement) and C. albicans was the most common species. The average number of yeasts in the oral cavity showed some fluctuation during the study but in general with an upward trend (adj. R2 = 0.7967, p = 0.07025). The correlation of median number of yeasts with periodontal indexes (API, GBI) was found. I n Candida-carries average API values decreased (adj. R 2 = 0.95; p = 0.01709), while in non- Candida -carriers average GBI values increased (adj. R 2 = 0.92; p = 0.0256).Conclusions: Treatment with orthodontic appliances promotes Candida yeast colonization which is variable over time in terms of strain and species, with domination of C. albicans, without an increased biofilm-forming activity. In carriers, the API value decreases over time, and in non-colonized patients the GBI value increases – which may have a predictive significance for the development of oral candidiasis during orthodontic treatment.

ABSTRACT Objective:  To compare the degree of debris and friction of conventional and self-ligating orthodontic brackets before and after clinical use. Materials and Methods:  Two sets of three conventional and self-ligating brackets were bonded from the first molar to the first premolar in eight individuals, for a total of 16 sets per type of brackets. A passive segment of 0.019 × 0.025-inch stainless steel archwire was inserted into each group of brackets. Frictional force and debris level were evaluated as received and after 8 weeks of intraoral exposure. Two-way analysis of variance and Wilcoxon signed-rank test were applied at P < .05. Results:  After the intraoral exposure, there was a significant increase of debris accumulation in both systems of brackets (P < .05). However, the self-ligating brackets showed a higher amount of debris compared with the conventional brackets. The frictional force in conventional brackets was significantly higher when compared with self-ligating brackets before clinical use (P < .001). Clinical exposure for 8 weeks provided a significant increase of friction (P < .001) on both systems. In the self-ligating system, the mean of friction increase was 0.21 N (191%), while 0.52 N (47.2%) was observed for the conventional system. Conclusion:  Self-ligating and conventional brackets, when exposed to the intraoral environment, showed a significant increase in frictional force during the sliding mechanics. Debris accumulation was higher for the self-ligating system.

ABSTRACT Objectives To evaluate and compare the biofilm formation between labial and lingual orthodontic brackets. Materials and Methods Twenty patients with a mean age of 24 ± 8.8 who had received labial or lingual orthodontic treatment were enrolled in the study. Biofilm formation on 80 brackets was analyzed quantitatively with the Rutherford backscattering detection method. Five micrographs were obtained per bracket with views from the vestibule/lingual, mesial, distal, gingival, and occlusal aspects. Quantitative analysis was carried out with surface analysis software (ImageJ 1.48). Data were analyzed by Mann-Whitney U and Kruskal-Wallis tests (α = 0.05). Results Total biofilm formation was 41.56% (min 29.43% to max 48.76%) on lingual brackets and 26.52% (min 21.61% to max 32.71%) on labial brackets. Differences between the two groups were found to be significant. No difference was observed in intraoral location. The biofilm accumulation was mostly located on gingival, mesial, and distal surfaces for both groups. Conclusions The biofilm accumulation on lingual orthodontic therapy was found to be more than labial orthodontic therapy.

Patients with Parkinson’s disease (PD) are at increased risk of aspiration pneumonia, their primary cause of death. Their oral microbiota differs from healthy controls, exacerbating this risk. Our goal was to explore if poor oral health, poor oral hygiene, and dysphagia status affect the oral microbiota composition of these patients. In this cross-sectional case-control study, the oral microbiota from hard and soft tissues of patients with PD (n = 30) and age-, gender-, and education-matched healthy controls (n = 30) was compared using 16S rRNA gene sequencing for bacterial identification. Study participants completed dietary, oral hygiene, drooling, and dysphagia questionnaires, and an oral health screening. Significant differences in soft tissue beta-diversity (p < 0.005) were found, and a higher abundance of opportunistic oral pathogens was detected in patients with PD. Factors that significantly influenced soft tissue beta-diversity and microbiota composition include dysphagia, drooling (both p < 0.05), and salivary pH (p < 0.005). Thus, patients with PD show significant differences in their oral microbiota compared to the controls, which may be due, in part, to dysphagia, drooling, and salivary pH. Understanding factors that alter their oral microbiota could lead to the development of diagnostic and treatment strategies that improve the quality of life and survivability of these patients.

The aim of this study was to evaluate the effect of toothpaste containing natural tea tree essential oil (TTO) and ethanolic extract of propolis (EEP), on microflora and selected indicators of oral health in patients using removable acrylic partial dentures. Fifty patients with varying conditions of hygiene were divided into two groups. The study group received the toothpaste with TTO and EEP, while the control group received the same toothpaste but without TTO and EEP. At the first visit, oral hygiene and hygiene of the prostheses were carried out. Control visits took place 7 and 28 days later and compared to baseline. Indexes like API (Approximal Plaque Index), mSBI (modified Sulcus Bleeding Index), OHI-s (simplified Oral Hygiene Index), and DPI (Denture Plaque Index) were assessed in three subsequent stages, and swabs were collected from floor of the mouth area to assess the microbiota. After 7 and 28 days of using the toothpaste with TTO and EEP, a statistically significant decrease of the examined indicator values were observed in the study group as compared to the values upon the initial visit. The number of isolated strains of microorganisms in the study group was decreased or maintained at the same level, whereas in the control group an increase in the number of isolated strains was observed. The observed stabilization of oral microbiota in patients from the study group confirms the beneficial activity of toothpaste containing EEP and TTO compared to the control group.

Objective: In recent years, advances in technique as well as a growing public interest in developing and maintaining a healthy and attractive smile, has resulted in a greater understanding of the interrelationships between periodontics and orthodontics. The primary objective of periodontal therapy is to restore and maintain the health and integrity of the attachment apparatus of teeth. In adults, the loss of teeth or periodontal support can result in pathological teeth migration involving either a single tooth or a group of teeth. This may result in the development of a diastema, incisal proclination, rotation with collapse of the posterior occlusion.Materials and methods: This case report is of a 32 year old female patient who reported with swollen gums, generalized spacing between the teeth and extruded upper anterior tooth. Periodontal therapy followed by fixed orthodontic therapy was planned.Results: At the end of 2 years a stable healthy periodontium was established that was both functional and esthetic.Conclusion: Adjunctive orthodontic therapy is often necessary for successful restoration of periodontal health. On the other hand, successful orthodontic treatment will depend on the periodontal preparation before and after treatment and the maintenance of periodontal health throughout all phases of mechano-therapy.

AbstractThe effects on carabids of natural, fescue, and rye sod types and of tillage were investigated in a pest management apple orchard. Carabids were sampled before and after the treatments by pitfall trapping and by two types of soil sampling. There were no significant effects of sod type on pitfall trap catches; however the abundance of all common species in soil samples was significantly affected by sod types. Usually in soil samples carabids were most abundant in natural sod and least abundant in tilled plots; numbers were intermediate in fescue and rye. Sod type did not affect structure or diversity of the carabid fauna.
