Candida sp in the oral cavity with and without lesions: maximal inhibitory dilution of Propolis and Periogard

Fifty individuals of both sexes aged on average 45.2 years were evaluated at the Semiology Clinic of FORP-USP in order to isolate and identify yeasts from the oral cavity, with and without lesions, and to determine the maximal inhibitory dilution (MID) of the commercial products Propolis (Apis-Flora) and Periogard (Colgate) against the strains isolated. Yeasts of the genus Candida were detected in the saliva of 9/19 (47.4%) individuals with a clinically healthy mouth, 18/22 (81.8%) of individuals with oral lesions, and in 4/9 (44.4%) of patients with deviation from normality, and were detected in 19/22 (86.4%) of the lesions. In the group with oral candidiasis, we isolated in tongue and lesion, respectively for each specie: C.tropicalis (8% and 10.7%), C.glabrata (4% and 3.6%) and C.parapsilosis (2% and 3.6%), in addition to C.albicans (71.4% and 67.8%) as the only species and the prevalent. The total cfu counts/ml saliva showed a higher mean value in the group with oral candidiasis (171.5% x 10(3)) than in the control group (72.6 x 10(3)) or the group with abnormalities (8.3 x 10(3)). Most of the test strains 67/70 (95.71%) were sensitive to the antiseptics, with Propolis presenting a MID of 1:20 for 54/70/77.1%), and Periogard a MID of 1:160 for 42/70 (60%) strains from healthy sites, results similar to those obtained with strains from oral lesions. Different results were mainly observed among different species. The results indicate the possibility of using the antiseptics Propolis and Periogard (chlorhexidine) for the prevention and treatment of oral candidiasis.

Objectives: The goal of the present study correlates dental hard tissue mineralization, mucosal pathologies in the oral cavity and different degrees of intestinal dysbiosis. Study Design: the study examined two groups: the study group (Group I) included 229 children and adolescents aged 1–17 (mean age 5±1years) with oral pathologies (caries, acute or chronic candidiasis) and confirmed dysbiosis of varying severity and stages as well. Group II (the Control Group) was composed of 50 patients aged 1 – 16 (mean age 5±1years) with oral pathologies but with no detected changes in gastrointestinal (GI) flora. Dental caries were examined by DMFT-index; the extent of dental hard tissue mineralization by vital staining (2% methylene blue) and cases of oral candidiasis was investigated by taking cultures from mucosal plaques. Results: on the basis of the research outcomes the correlation between the different degrees of GI dysbiosis and dental hard tissue mineralization with pathologic expressions in the oral cavity was found. Group I was divided into two subgroups: in the first subgroup that suffered from mild dysbiosis (I and II degree) moderate dental caries was revealed, whereas in the second subgroup with III and IV degree of dysbiosis–high levels of dental caries was detected. In Group II (no GI flora disturbances), the dental hard tissue demineralization indicator was minimal; in children aged 1–3 years the incidence and prevalence of caries were low and increased with age, reaching higher values during puberty (11–16 years). Conclusion: It may be concluded that dysbiosis of GI microflora influences on a degree of dental hard tissue demineralization, which in turn may predispose to the formation of dental caries.

Coronavirus disease 2019 (COVID-19) is a threat to the global health caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The lungs are the primary site of infection in COVID-19 patient and the symptoms ranges from mild flu like manifestations to fulminant pneumonia and respiratory failure. COVID-19 infection also significantly affects the oral cavity and salivary glands with oral mucosal manifestations. Other than airway manifestations, COVID-19 patients are presenting with oral cavity lesions such as aphthous like ulcers, glossitis, oral mucositis or stomatitis, oral candidiasis and herpetic recurrences. These oral lesions are often associated with immunocompromised patients and elderly age. Direct involvement of the SARS-CoV-2 virus for development of oral ulcers remains uncertain. The salivary gland related symptoms and taste disturbances are highly common in COVID-19 patients. In COVID-19 patient, certain presentations like ulcers or blisters or diffuse reddish lesions affect both keratinized and non-keratinized tissues of the oral cavity. These lesions are found in palate, lip mucosa, buccal mucosa and tongue. The ulceration and blisters of the oral cavity are more often seen. There is still a gap of knowledge related to the oral manifestations of the COVID-19 infections and its impact on the oral cavity. This review article discussed the details of the oral cavity lesions in COVID-19 patients.

ABSTRACT Probiotics might provide an alternative approach for the control of oral candidiasis. However, studies on the antifungal activity of probiotics in the oral cavity are based on the consumption of yogurt or other dietary products, and it is necessary to use appropriate biomaterials and specific strains to obtain probiotic formulations targeted for local oral administration. In this study, we impregnated gellan gum, a natural biopolymer used as a food additive, with a probiotic and investigated its antifungal activity against Candida albicans. Lactobacillus paracasei 28.4, a strain recently isolated from the oral cavity of a caries-free individual, was incorporated in several concentrations of gellan gum (0.6% to 1% [wt/vol]). All tested concentrations could incorporate L. paracasei cells while maintaining bacterial viability. Probiotic-gellan gum formulations were stable for 7 days when stored at room temperature or 4°C. Long-term storage of bacterium-impregnated gellan gum was achieved when L. paracasei 28.4 was lyophilized. The probiotic-gellan gum formulations provided a release of L. paracasei cells over 24 h that was sufficient to inhibit the growth of C. albicans, with effects dependent on the cell concentrations incorporated into gellan gum. The probiotic-gellan gum formulations also had inhibitory activity against Candida sp. biofilms by reducing the number of Candida sp. cells (P < 0.0001), decreasing the total biomass (P = 0.0003), and impairing hyphae formation (P = 0.0002), compared to the control group which received no treatment. Interestingly, a probiotic formulation of 1% (wt/vol) gellan gum provided an oral colonization of L. paracasei in mice with approximately 6 log CFU/ml after 10 days. This formulation inhibited C. albicans growth (P < 0.0001), prevented the development of candidiasis lesions (P = 0.0013), and suppressed inflammation (P = 0.0006) compared to the mice not treated in the microscopic analysis of the tongue dorsum. These results indicate that gellan gum is a promising biomaterial and can be used as a carrier system to promote oral colonization for probiotics that prevent oral candidiasis.

Mucosal Lesions

Background: Oral mucosa reflects the general health of an individual. In certain systemic diseases oral cavity may be affected first or it could the only clue to diagnosis. Hence skin examination is never complete without the examination of mucosae. Aims and objectives were to find out the frequency and diversity of oral mucosal lesions in patients attending Dermatology, Venereology and Leprosy (DVL) outpatient department (OPD).Methods: This was a hospital based observational study. All patients with oral mucosal lesions fulfilling the inclusion &exclusion criteria were enrolled in the study. Detailed history, physical examination and clinical photographs were recorded for all the patients.Results: The prevalence oral mucosal lesions among dermatological patients is 1.04% with a female predilection and the mean age was 38.44±17.30. Majority of the patients belonged to the age group of 31-60 years. Established risk factors for developing oral lesions like tobacco and beetle nut use was found in only 24% and 16% of the patients respectively. Twenty% (21%) of the patients were diabetic and the commonest oral lesions in them was oral candidiasis. Eighteen% (18%) of the patients presented with only oral complaints, while 82% of patients came with skin complaints and their oral lesions were incidental findings. Out of 82 patients with dermatological diseases specific mucocutaneous diseases were seen in 44% of patients. Most common dermatological diseases seen were vitiligo, lichen planus and pemphigus vulgaris.Conclusions: Knowing the prevalence of oral lesions as a part of mucocutaneous disorders would help sensitise other specialities the need to examine oral cavity in order to attain appropriate and early diagnosis.

Introduction The oral cavity and pharynx have a rich sensory system composed of specialized receptors. The integrity of oropharyngeal sensation is thought to be fundamental for safe and efficient swallowing. Chronic obstructive pulmonary disease (COPD) patients are at risk for oropharyngeal sensory impairment due to frequent use of inhaled medications and comorbidities including gastroesophageal reflux disease. Objective This study aimed to describe and compare oral and oropharyngeal sensory function measured using noninstrumental clinical methods in adults with COPD and healthy controls. Method Participants included 27 adults (18 men, nine women) with a diagnosis of COPD and a mean age of 66.56 years ( SD = 8.68). The control group comprised 11 healthy adults (five men, six women) with a mean age of 60.09 years ( SD = 11.57). Spirometry measures confirmed reduced functional expiratory volumes (% predicted) in the COPD patients compared to the control participants. All participants completed a case history interview and underwent clinical evaluation of oral and oropharyngeal sensation by a speech-language pathologist. The sensory evaluation explored the detection of tactile and temperature stimuli delivered by cotton swab to six locations in the oral cavity and two in the oropharynx as well as identification of the taste of stimuli administered in 5-ml boluses to the mouth. Analyses explored the frequencies of accurate responses regarding stimulus location, temperature and taste between groups, and between age groups (“≤ 65 years” and “> 65 years”) within the COPD cohort. Results We found significantly higher frequencies of reported use of inhaled medications ( p < .001) and xerostomia ( p = .003) in the COPD cohort. Oral cavity thermal sensation ( p = .009) was reduced in the COPD participants, and a significant age-related decline in gustatory sensation was found in the COPD group ( p = .018). Conclusion This study found that most of the measures of oral and oropharyngeal sensation remained intact in the COPD group. Oral thermal sensation was impaired in individuals with COPD, and reduced gustatory sensation was observed in the older COPD participants. Possible links between these results and the use of inhaled medication by individuals with COPD are discussed.

The aim of this study was to evaluate the effect of implant surface treatment with carboxyethylphosphonic acid and fibroblast growth factor 2 on the bone–implant interface during the osseointegration period in vivo using an animal model. The present research was carried out in six minipigs, in whose left tibia implants were inserted as follows: eight implants with a standard surface treatment, for the control group, and eight implants with a surface treatment of carboxyethylphosphonic acid and immobilization of FGF-2, for the test group. At 4 weeks after the insertion of the implants, the animals were sacrificed for the histomorphometric analysis of the samples. The means of the results for the implant–bone contact variable (BIC) were 46.39 ± 17.49% for the test group and 34.00 ± 9.92% for the control group; the difference was not statistically significant. For the corrected implant–bone contact variable (BICc), the mean value of the test group was 60.48 ± 18.11%, and that for the control group, 43.08 ± 10.77%; the difference was statistically significant (p-value = 0.035). The new bone formation (BV/TV) showed average results of 27.28 ± 3.88% for the test group and 26.63 ± 7.90% for the control group, meaning that the differences were not statistically significant (p-value = 0.839). Regarding the bone density at the interthread level (BAI/TA), the mean value of the test group was 32.27 ± 6.70%, and that of the control group was 32.91 ± 7.76%, with a p-value of 0.863, while for the peri-implant density (BAP/TA), the mean value of the test group was 44.96 ± 7.55%, and that for the control group was 44.80 ± 8.68%, without a significant difference between the groups. The current research only found a significant difference for the bone–implant contact at the cortical level; therefore, it could be considered that FGF-2 acts on the mineralization of bone tissue. The application of carboxyethylphosphonic acid on the surface of implants can be considered a promising alternative as a biomimetic coating for the immobilization of FGF-2. Despite no differences in the new bone formation around the implants or in the interthread or peri-implant bone density being detected, the biofunctionalization of the implant surface with FGF-2 accelerates the mineralization of the bone–implant interface at the cortical level, thereby reducing the osseointegration period.

AbstractSerum immunoglobulin (IgG, IgA and IgM) levels were determined in patients with chronic tonsillitis before and one month after tonsillectomy. The preoperative levels of serum IgG, IgA and IgM were significantly higher when compared with the controls. The increase may be due to repeated antigenic stimulation. The post-operative levels for the three immunoglobulins were decreased; however, a significant reduction was observed for IgG only where the mean value was comparable with the control group. The data confirm that tonsillectomy does not disturb the humoral immune system of the body.
