AI Article Synopsis
- The study aimed to investigate the relationship between oral yeasts carriage (OYC) and the effects of habitual smoking and prediabetes among cigarette smokers and nonsmokers.
- Four groups were examined: prediabetic smokers, smokers without prediabetes, prediabetic nonsmokers, and nonsmokers without prediabetes, with various oral health metrics assessed.
- Results indicated that prediabetic smokers had the highest OYC, and dental health indicators such as plaque and attachment loss were poorer in smokers, with significant differences between the smoking and nonsmoking groups related to OYC levels.
Article Abstract
Background: Habitual smoking and prediabetes are independent risk factors for increased oral yeasts carriage (OYC); however, no studies have compared OYC amongst cigarette smokers and nonsmokers with and without prediabetes. The aim was to fill this research gap.
Methods: Ninety-two participants were included and categorised into 4 groups: group 1, prediabetic (haemoglobin A1c [HbA1c] levels, 5.7%-6.4%) cigarette smokers; group 2, cigarette smokers without prediabetes; group 3, prediabetic nonsmokers; and group 4, nonsmokers without prediabetes. Patient demographics and HbA1c levels were recorded. Data on duration of smoking habit (pack-years) and family history of smoking were collected. Information on daily toothbrushing and flossing and most recent visit to a dentist/dental hygienist was gathered. Clinical and radiographic periodontal examination was performed and unstimulated whole salivary flow rate (UWSFR) was determined. OYC was assessed using the oral rinse sampling method. Power analysis was done, and group comparisons were performed. Logistic regression analysis was performed and P values <5% reflected statistical significance.
Results: Respectively, 23, 24, 22, and 23 individuals with comparable mean ages were included in groups 1, 2, 3, and 4. In groups 1 and 2, participants had a smoking history of (mean ± SD) 24.7 ± 3.2 and 10.6 ± 2.5 pack-years. Plaque index, clinical attachment loss, and probing depth were higher in groups 1 (P < .05), 2 (P < .05), and 3 (P < .05) than in group 4. Number of missing teeth was significantly higher in group 1 compared with groups 2 (P < .05), 3 (P < .05), and 4 (P < .05). There was no difference in UWSFR amongst the groups. OYC was greater in group 1 than in groups 2 (P < .05), 3 (P < .05), and 4 (P < .05). OYC was greater in groups 2 (P < .05) and 3 (P < .05) than in group 4.
Conclusions: In prediabetic cigarette smokers, OYC appears to be influenced by hyperglycaemia, whilst in nondiabetic smokers, the severity of periodontal inflammation appears to be the determining factor in OYC.

Objective: To compare the salivary profiles of smokers (e-cigarette smokers, e-cigarette and former conventional cigarette smokers, dual users, and conventional cigarette smokers) and non-smokers in adolescents, focusing on acidity level, flow rate, viscosity, as well as the quantity of Streptococcus mutans, Porphyromonas gingivalis, and Candida albicans.
Methods: This analytical observational study, with a cross-sectional design, involves collecting saliva samples from five groups through the draining method. Saliva viscosity was assessed visually, while saliva flow rate was monitored over a ten-minute period.

Objectives: The use of electronic cigarettes "e-cigarettes," or vaping is growing in popularity, especially among adolescents and young adults. While the effects of cigarette smoking on oral health are well-established, the exact impact that e-cigarettes may have on dental tissues is still uncertain. The aim of the current review was to summarize evidence related to the effect of vaping on the periodontal health status of e-cigarette users.
