[PMID: 38692958 DOI: 10.1016/j.oooo.2024.03.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 12/05/2023] [Accepted: 03/17/2024] [Indexed: 05/03/2024]
Abstract
OBJECTIVE To analyze the effect of hookah and cigarettes on the oral mucosa of smokers through the use of exfoliative cytology. STUDY DESIGN Smear samples were collected by exfoliative cytology from the tongue of 33 hookah smokers, 22 cigarette smokers, and 30 non-smokers. The selected analyses include micronuclei (MN), metanuclear anomalies, epithelial maturation, and cytomorphology (nuclear area [NA], cytoplasmic area [CA], and NA/CA ratio). RESULTS The largest differences observed for MN and metanuclear anomalies were between cigarette smokers and the control group (notably 1 MN P = .04; total cells with MN P = .039; total MN P = .042; karyorrhexis and binucleation, P = .0001). The hookah group, compared with the control group, showed the greatest differences for karyolysis (P = .0023), binucleation (P = .0003), and broken egg (P = .008). Significant differences were found between the smokers and the control groups regarding changes in the superficial cell without nucleus, perinuclear halo, vacuolization, color change, mucus, and keratohyalin granules. There was a significant increase in the NA and NA/CA ratio in the smoker groups. CONCLUSION This study showed that a combined analysis of exfoliative cytology associated with other diagnostic methods is a useful tool for studying oral carcinogenesis. Hookah and cigarettes showed similar effects in terms of displaying substantial cytogenetic and cytotoxic damage.

Ali D, Al-Yahya QM, Baskaradoss JK. Peri-Implant Inflammation in Waterpipe Users and Cigarette Smokers: An Observational Study. Int Dent J 2023; 73:717-723. [PMID: 37037698 PMCID: PMC10509447 DOI: 10.1016/j.identj.2023.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Revised: 03/12/2023] [Accepted: 03/14/2023] [Indexed: 04/12/2023] Open
Abstract
OBJECTIVE The aim of this study was to compare peri-implant clinical and radiographic status and levels of advanced glycation endproducts (AGEs) in peri-implant sulcular fluid (PISF) in waterpipe users and cigarette smokers. METHODS Waterpipe users, cigarette smokers, and never smokers were included. Demographic details were collected using a questionnaire. Characteristics of implants (dimensions, jaw location, depth of placement, insertion torque, and duration in function) were recorded. Peri-implant modified plaque and gingival indices (mPI and mGI), probing depth (PD), and crestal bone loss (CBL) were recorded in all groups. Volume of PISF and levels of AGEs were determined using standard techniques. Sample-size estimation was done on data from a pilot investigation, and correlation between clinicoradiographic and immunoinflammatory parameters was assessed using logistic regression models. Probability values <.05 were considered statistically significant. RESULTS In all, 25, 25, and 24 cigarette smokers, never smokers, and waterpipe users, respectively, were examined. All participants were male and had comparable mean ages. Cigarette smokers and waterpipe users had a smoking history of 20.2 ± 3.5 years and 18.8 ± 0.6 years, respectively. The mPI (P < .01), CBL (P < .01), PD (P < 0.01), and mGI (P < .01) were significantly higher in cigarette smokers and waterpipe users than never smokers. There was no significant difference in clinicoradiographic status and AGE concentrations in waterpipe users and cigarette smokers. A statistically significant correlation was recorded between AGEs and PD in cigarette smokers (P < .01) and waterpipe users (P < .01). CONCLUSIONS Waterpipe usage is not less hazardous to peri-implant tissue health than conventional cigarette smoking. It is imperative to caution patients with dental implants about the detrimental effects of tobacco products on oral health.

Abstract
PURPOSE The purpose of this paper is to present evidence regarding the associations between smoking and the following urologic cancers: prostate, bladder, renal, and upper tract urothelial cancer (UTUC). METHODS This is a narrative review. PubMed was queried for evidence-based analyses and trials regarding the associations between smoking and prostate, bladder, renal, and UTUC tumors from inception to September 1, 2022. Emphasis was placed on articles referenced in national guidelines and protocols. RESULTS Prostate-multiple studies associate smoking with higher Gleason score, higher tumor stage, and extracapsular invasion. Though smoking has not yet been linked to tumorigenesis, there is evidence that it plays a role in biochemical recurrence and cancer-specific mortality. Bladder-smoking is strongly associated with bladder cancer, likely due to DNA damage from the release of carcinogenic compounds. Additionally, smoking has been linked to increased cancer-specific mortality and higher risk of tumor recurrence. Renal-smoking tobacco has been associated with tumorigenesis, higher tumor grade and stage, poorer mortality rates, and a greater risk of tumor recurrence. UTUC-tumorigenesis has been associated with smoking tobacco. Additionally, more advanced disease, higher stage, lymph node metastases, poorer survival outcomes, and tumor recurrence have been linked to smoking. CONCLUSION Smoking has been shown to significantly affect most urologic cancers and has been associated with more aggressive disease, poorer outcomes, and tumor recurrence. The role of smoking cessation is still unclear, but appears to provide some protective effect. Urologists have an opportunity to engage in primary prevention by encouraging cessation practices.

Genotoxicity of waterpipe smoking in young adults from Sarajevo, Bosnia & Herzegovina. Heliyon 2023; 9:e17073. [PMID: 37332975 PMCID: PMC10276226 DOI: 10.1016/j.heliyon.2023.e17073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 06/05/2023] [Accepted: 06/06/2023] [Indexed: 06/20/2023] Open
Abstract
Background Waterpipe, also known as a hookah or narghile, is a type of tobacco products consumption device. Recently it has been increasingly popular in Bosnia and Herzegovina and the region. Waterpipe consumers are predominantly adolescents and young adults. Many of them believe in slighter harmful effects of waterpipes, compared to cigarettes. We aimed to determine the DNA damage in oral leukocytes and buccal cells of young individuals who have smoked a waterpipe for more than one year. Methods The study group consisted of 40 cigarette non-smokers who regularly smoked a waterpipe on average of once per week. As a control, 40 non-smoking individuals were selected to match smokers for age. All participants in the study were healthy male and female adults from Bosnia and Herzegovina, 18-30 years of age. Before sampling, detailed survey and informed consent have been provided by each participant. Comet assay in oral leukocytes and buccal micronucleus cytome (BMCyt) assay in exfoliated buccal cells were applied. Results Almost half of waterpipe smokers (WPS) tasted waterpipe at 15-16 years of age. Comet assay analysis showed increased tail intensity, tail length, and tail moment values among WPS compared to non-smokers (NS) (p = 0.0001, p = 0.0067, and p = 0.0001, respectively). Frequencies of the micronucleated (p = 0.0004), binucleated (p = 0.01), karyorrhectic, (p = 0.0036), and pycnotic cells (p = 0.03) were significantly higher in WPS compared to NS group. Conclusions Genotoxicity and DNA damage biomarkers were increased in oral leukocytes and exfoliated buccal cells of young waterpipe smokers from Bosnia and Herzegovina, compared to NS group.

Abstract
Food habits and oral hygiene are critical attributes for physiochemical environment of the oral cavity. Consumption of intoxicating substances such as betel nut ('Tamul'), alcohol, smoking and chewing tobacco may strongly influence the oral ecosystem including commensal microbes. Therefore, a comparative assessment of microbes in the oral cavity between individuals consuming intoxicating substances and non-consumers may indicate the influence of these substances. Oral swabs were collected from consumers of intoxicating substances and non- consumers of Assam, India, microbes were isolated by culturing on Nutrient agar and identified by phylogenetic analysis of their 16S rRNA gene sequences. The risks of consumption of intoxicating substance on occurrence of microbes and health conditions were estimated using binary logistic regression. Mostly pathogens and opportunistic pathogens were found in the oral cavity of consumers and oral cancer patients which included Pseudomonas aeruginosa, Serratia marcescens, Rhodococcus antrifimi, Paenibacillus dendritiformis, Bacillus cereus, Staphylococcus carnosus, Klebsiella michiganensis and Pseudomonas cedrina. Enterobacter hormaechei was found in the oral cavity of cancer patients but not in other cases. Pseudomonas sp. were found to be widely distributed. The risk of occurrence of these organisms were found in between 0.01 and 2.963 odds and health conditions between 0.088 and 10.148 odds on exposure to different intoxicating substances. When exposed to microbes, the risk of varying health conditions ranged between 0.108 and 2.306 odds. Chewing tobacco showed a higher risk for oral cancer (10.148 odds). Prolonged exposure to intoxicating substances conduce a favorable environment for the pathogens and opportunistic pathogens to colonize in the oral cavity of individuals consuming intoxicating substances.

Abstract
Smoking increases the risk of a number of diseases, including cardiovascular, oral and lung diseases. E-cigarettes are gaining popularity among young people as an alternative to cigarettes, but there is debate over whether they are less harmful to the mouth than e-cigarettes. In this study, human gingival epithelial cells (HGECs) were treated with four commercially available e-cigarette aerosol condensates (ECAC) or commercially available generic cigarette smoke condensates (CSC) with different nicotine concentrations. Cell viability was determined by MTT assay. Cell apoptosis was observed by acridine orange (AO) and Hoechst33258 staining. The levels of type I collagen, matrix metalloproteinase (MMP-1, MMP-3), cyclooxygenase 2 and inflammatory factors were detected by ELISA and RT-PCR. Finally, ROS levels were analyzed by ROS staining. The different effects of CSC and ECAC on HGECs were compared. The results showed that higher nicotine concentration of CS significantly reduced the activity of HGECs. By contrast, all ECAC had no significant effect. The levels of matrix metalloproteinase, COX-2, and inflammatory factors were higher in HGECs treated with CSC than those treated with ECAC. In contrast, the level of type I collagen was higher in HGECs treated with ECAC than those treated with CSC. In conclusion, all four flavors of e-cigarettes were less toxic to HGE cells than tobacco, but further clinical studies are needed to determine whether e-cigarettes are less harmful to oral health than conventional cigarettes.

Abstract
Electronic cigarette (EC) usage or vaping has seen a significant rise in recent years across various parts of the world. They have been publicized as a safe alternative to smoking; however, this is not supported strongly by robust research evidence. Toxicological analysis of EC liquid and aerosol has revealed presence of several toxicants with known carcinogenicity. Oral cavity is the primary site of exposure of both cigarette smoke and EC aerosol. Role of EC in oral cancer is not as well-researched as that of traditional smoking. However, several recent studies have shown that it can lead to a wide range of potentially carcinogenic molecular events in oral cells. This review delineates the oral carcinogenesis potential of ECs at the molecular level, providing a summary of the effects of EC usage on cancer therapy resistance, cancer stem cells (CSCs), immune evasion, and microbiome dysbiosis, all of which may lead to increased tumor malignancy and poorer patient prognosis. This review of literature indicates that ECs may not be as safe as they are perceived to be, however further research is needed to definitively determine their oncogenic potential.

Abstract
Oral nicotine pouches are emerging as a new "modern oral" nicotine product. These prefilled pouches contain nicotine, flavorings, and filling agents that dissolve in the mouth. Nicotine can be derived from tobacco leaf or chemical synthesis. Traces of TSNAs and toxic chromium were detected in the pouch products. This raises the concern about general and periodontal health. This review aims to update the current oral nicotine products research relating to periodontal disease and its relevance in periodontal inflammation. Nicotine interacts with host cells and affects inflammatory responses to microbial challenges. It may directly or indirectly deteriorate periodontal tissues by activating nicotinic acetylcholine receptors, repressing PDL fibroblasts cells, increasing cellular ROS and cytokines/chemokines, growth factors, breaking microbiota balance, and dysregulating miRNAs expression. Studies show that appealing flavorings contained in nicotine pouches pose harm to periodontal innate immune responses and increase penetration of nitrosamines. In addition, flavored ONPs increase the risk of dual or poly-tobacco products among young adults, stacking up detrimental effects on the periodontium. Given the recent growth of users, further studies are needed to elucidate the impact of ONPs, even poly-tobacco use, on systemic and periodontal health. Moreover, policymakers should ensure to avoid generating a new wave of nicotine addiction among youths in the U.S.

Abstract
Introduction To describe the recent prevalence of, and trends in, waterpipe smoking and to examine its associated factors among adolescents aged 12-16 years in 73 countries/territories (hereafter "countries"). Methods Data from 72 countries that had conducted a Global Youth Tobacco Survey (GYTS) in 2010-2019 and from the National Youth Tobacco Survey in the United States in 2019 were used to assess the recent prevalence of waterpipe smoking and to examine its associated factors among adolescents aged 12-16 years. Data from 38 countries that had carried out at least 2 surveys from 2000 to 2019 were used to determine trends in the prevalence of waterpipe smoking among adolescents. Results The recent prevalence of current waterpipe smoking (on 1 day during the past 30 days) among adolescents was 6.9% (95%CI 6.4-7.5). The prevalence was highest in the European region (10.9%, 9.9-11.8) and Eastern Mediterranean region (10.7%, 9.5-11.9), but lowest in the Western Pacific region (1.9%, 1.4-2.4). The prevalence of current waterpipe smoking increased or remained unchanged in 19 (50%) of 38 countries, but decreased in the remaining 19 countries (50%). Parental smoking, closest friends' smoking, secondhand smoke exposure, tobacco advertisement exposure, not being taught the dangers of smoking, particularly cigarette smoking, were positively associated with adolescent waterpipe smoking. Discussion Waterpipe smoking among adolescents remains a major public health issue worldwide, especially in the regions of Europe and the Eastern Mediterranean. Effective prevention and control strategies and measures are needed to curb the epidemic of adolescent waterpipe smoking.

Population attributable fraction of lung cancer due to genetic variants, modifiable risk factors, and their interactions: a nationwide prospective cohort study. CHEMOSPHERE 2022; 301:134773. [PMID: 35500626 DOI: 10.1016/j.chemosphere.2022.134773] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 04/01/2022] [Accepted: 04/26/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Genetic variants and modifiable risk factors (including environmental exposure and lifestyle) greatly contribute to the development of lung cancer. The population attributable fraction (PAF) of these risk factors, especially their interactive effects, has not been well quantified. METHODS A total of 398,577 participants were included in this analysis. There were 2504 incident lung cancer cases identified over an average 10.4-year follow-up. We applied Cox proportional hazards models to examine the associations between risk factors and incident lung cancer. We further developed a polygenic risk score and evaluated whether environmental factors modified the effect of genetic risk on incident lung cancer. Furthermore, we calculated the PAF for each risk factor, as well as their gene-environment additive interaction, and then combined them to create a weighted PAF that takes into consideration participants with overlapping risk factors. RESULTS Our analysis showed that smoking was the leading risk factor for lung cancer with a PAF of 63.73%. We observed additive interactions between smoking, PM2.5, NOx, and genetic risk, with PAFs of 17.85% (smoking-high genetic risk interaction), 10.79% (smoking-intermediate genetic risk interaction), 5.30% (NOx-high genetic risk interaction), 6.55% (PM2.5-high genetic risk interaction), and 4.99% (PM2.5-intermediate genetic risk interaction). We estimated that 73.46% of lung cancer cases could be attributable to potentially modifiable risk factors after adjusting for the correlation between them. CONCLUSION High genetic risk and several modifiable factors may increase the risk of incident lung cancer. Participants with a high genetic risk may be more vulnerable to developing lung cancer if exposed to smoking and/or high air pollution. Our findings provide evidence that the majority of incident lung cancer cases could be prevented by eliminating modifiable risk factors.

Abstract
INTRODUCTION There is an established link between tobacco use and adverse oral health outcomes. However, there is a paucity of research exploring the effect of various tobacco products on clinically diagnosed adverse oral health outcomes. METHODS Data were pooled from three cycles of the National Health and Nutrition Examination Survey: 2009-2010; 2011-2012; and 2013-2014 (n = 11,453). Multivariable logistic regressions examined the associations between periodontitis and dental caries with the type of tobacco product used (combustible, non-combustible or both). RESULTS Overall, 42.3% of the study sample had any periodontitis, 7.8% had severe periodontitis and 21.7% had dental caries. There was a higher prevalence of periodontitis and caries among combustible tobacco users than non-combustible tobacco use; 62.1% of combustible tobacco smokers had any periodontitis, 17.1% had severe periodontitis, while 39.4% of adults with dental caries were dual users. Compared to non-smokers, combustible tobacco use increased the odds of any periodontitis (adjusted odds ratio [aOR] 2.81, 95% confidence interval [CI] 2.28, 3.45) and severe periodontitis (aOR 2.62, 95% CI 1.90, 3.61). Compared to non-smokers, both combustible tobacco (aOR 2.11, 95% CI 1.61, 2.76) and non-combustible tobacco use (aOR 2.09, 95% CI 1.19, 3.66) increased the odds of dental caries. DISCUSSION AND CONCLUSIONS In this study of US adults, combustible tobacco use was associated with periodontitis and dental caries, while non-combustible tobacco use was associated with dental caries. In addition to conducting extensive oral health screening among all smokers, oral health-care providers should counsel smokers on the need for smoking cessation.

Abstract
ObjectivesWe conducted a 6-month randomized clinical study to evaluate the impact of exposure to the aerosol of the Tobacco Heating System (THS), a smoke-free alternative to cigarettes, on changes in periodontal parameters after scaling and root planing (SRP) for periodontitis in subjects who were either continuing to smoke cigarettes or had switched to THS.Material and methodsSmokers with generalized periodontitis were randomized to continue smoking cigarettes or switch to THS use. They underwent SRP for up to 8 weeks, with dental assessments conducted at baseline and at 3 and 6 months after the first treatment.ResultsAfter SRP treatment, all groups showed improvements in the mean full-mouth probing depth (PD), full-mouth clinical attachment level (CAL), gingival inflammation score, plaque control record (PCR), and bleeding on probing (BoP). There were no statistically significant intergroup differences. However, as compared to smokers, THS users showed a trend toward more favorable outcomes in BoP, PCR, and PD improvement at sites with higher initial PD (≥7 mm).ConclusionsOur results indicate that SRP improves the course of periodontitis similarly in cigarette smokers and THS users. The beneficial effects of this treatment might mask the favorable changes that may occur upon modifying one of the several periodontitis risk factors, such as cigarette smoking.Clinical trial registrationClinicalTrials.gov, identifer: NCT03364751.

Abstract
Dry socket is one of the postoperative complications of tooth extraction. It is the partial or total loss of the post-extraction blood clot, resulting in severe pain that usually starts one to five days postoperatively, with clinical evidence of exposed alveolar bone, necrotic debris, halitosis, and tenderness on examination. The purpose of our systematic review was to answer the question "Is there a relationship between smoking and dry socket?". After meeting the inclusion and exclusion criteria, eleven studies were included in this systematic review (according to the PRISMA statement guidelines). Based on a meta-analysis, tobacco smokers had a more than three-fold increase in the odds of dry socket after tooth extraction. Overall, the combined incidence of dry socket in smokers was found to be about 13.2% and in non-smokers about 3.8%. Despite the heterogeneity of the included studies (different types of teeth extracted, different age groups), cigarette smoking was related to an increased risk of dry socket after tooth extraction.

Periodontal and Peri-Implant Health Status in Traditional vs. Heat-Not-Burn Tobacco and Electronic Cigarettes Smokers: A Systematic Review. Dent J (Basel) 2022; 10:103.

Abstract
The aim of the present systematic review was to evaluate and possibly differentiate the effects of traditional cigarettes, heat-not-burn tobacco, and electronic cigarettes on periodontal and peri-implant health status. Electronic cigarettes and heat-not-burn tobacco have become very popular in recent years and have been proposed to consumers as a safer alternative to conventional tobacco smoke, although their effect on periodontal and peri-implant health remains unclear. The study protocol was developed according to PRISMA guidelines, and the focus question was formulated according to the PICO strategy. A literature search was conducted across PubMed/MEDLINE and the COCHRANE library from 2003 to April 2022. From the 1935 titles initially identified, 18 articles were finally included in the study and extracted data were qualitatively synthesized. It may be carefully concluded that e-cigarettes may cause attenuated clinical inflammatory signs of periodontitis and, hypothetically, of peri-implantitis when compared to conventional tobacco smoke. Both alternative smoking products, containing nicotine, may likewise exert negative effects on periodontal and peri-implant health, as demonstrated by in vitro studies. Further investigations are needed to assess the impact of electronic cigarettes and heat-not-burn tobacco products on periodontal and peri-implant health status.

Abstract
OBJECTIVES There is a lack of evidence exploring experiences of using e-cigarettes for smoking cessation. The study's main aim was to explore participant experiences of e-cigarettes compared to nicotine replacement therapy (NRT) delivered through stop smoking services. METHODS Semi-structured, face-to-face, and telephone interviews at 3-month post-quit follow-up in a randomized controlled trial comparing nicotine-containing e-cigarettes, nicotine-free e-cigarettes, and NRT for smoking cessation. N = 17 participants, 9 were male, mean age 44 years, 5 using nicotine-containing e-cigarettes, 7 nicotine-free e-cigarettes, and 5 NRT. Interviews were transcribed and analyzed using thematic analysis. RESULTS Two global themes and 5 organizing themes were identified. Global themes included: (1) experiences of e-cigarette and NRT quit aids (e-cigarette positive impact and dilemmas, NRT perceptions and experiences), and (2) key mechanisms to support quit attempt (physical aids, advice and support, feedback and structure). E-cigarettes were viewed with caution, however, generally evaluated positively alongside NRT methods, finding e-cigarettes useful during a quit attempt due to their versatility in application. Nicotinecontaining e-cigarettes were favored due to their support with nicotine cravings. Participants were, however, wary of replacing smoking addiction with vaping habit. CONCLUSIONS Participant e-cigarette experience were generally positive; however, concerns over long-term application were noted. There was a noticeable preference for nicotine-containing e-cigarettes, but further research is required to better understand how nicotine is used in conjunction with e-cigarettes long-term as a quit aid alongside other NRT.

Abstract
Introduction: Shisha, a form of smoking tobacco is known to be detrimental to oral health. Yet, the effects of shisha on oral health is not well documented. Hence, this study was undertaken to compare the clinical and cytological findings in oral cavity of young shisha smokers as compared to non-smokers. Materials and methods: A cross-sectional analytical study was undertaken among 60 subjects including 30 young shisha smokers and 30 non-smokers. Clinical examination was carried out to record gingival status, periodontal status, oral hygiene and dental caries experience. Exfoliative cytology was used to study the cytological changes of buccal mucosal cells. Data was analysed using SPSS version 22. Student’s t-test, Fisher’s exact test and odd’s ration was used for comparison. p < 0.05 was considered statistically significant. Results: No significant differences were found between the groups with respect to proportion of subjects with gingivitis (p = 0.071), erosion (p = 0.085) and dental caries experience (p = 0.329). However, shisha smokers had poorer oral hygiene and more severe gingival inflammation as compared to non-smokers with p = 0.026 and p = 0.007 respectively. The odds of having atypical cells in oral mucosa among shisha smokers was 3.76 times higher than the non-smokers. Conclusion: The findings of our study showed that young shisha smokers had more atypical cells in oral mucosa as compared to their non-smoking counterparts. However, longitudinal studies are needed to affirm the findings of this study.

Abstract
Oral cancer is one of the leading causes of death worldwide, with a reported 5-year survival rate of around 50% after treatment. Epigenetic modifications are considered to have a key role in oral carcinogenesis due to histone modifications, aberrant DNA methylation, and altered expression of miRNAs. MicroRNAs (miRNAs) are small non-coding RNAs that have a key role in cancer development by regulating signaling pathways involved in carcinogenesis. MiRNA deregulation identified in oral cancer has led to the idea of using them as potential biomarkers for early diagnosis, prognosis, and the development of novel therapeutic strategies. In recent years, a key role has been observed for risk factors in preventing and treating this malignancy. The purpose of this review is to summarize the recent knowledge about the altered mechanisms of oral cancer due to risk factors and the role of miRNAs in these mechanisms.

Abstract
A wealth of research has comprehensively documented the harmful effects of traditional cigarette smoking and nicotine on human health. The lower rate of exposure to harmful chemicals and toxic substances offered by alternative electronic smoking devices (e-cigarettes, vaping, etc.) has made these methods of smoking popular, especially among adolescents and young adults, and they are regarded frequently as safer than regular cigarettes. During vaporization of these so-called e-liquids, toxins, carcinogens and various other chemical substances may be released and inhaled by the user. Data on the potential human health effect attendant on exposure to e-vapor are based mainly on animal and in vitro studies. The oral tissues are the first locus of direct interaction with the components of the inhaled vapor. However, the short-term as well as long-term effects of the exposure are not known. The aim of the review is to briefly present data on the effects of the chemical components and toxins of e-cigarette vapor on oral cavity cells and tissues of oral health.

Abstract
OBJECTIVES E-cigarette use has become popular, particularly among the youth. Its use is associated with harmful general and oral health consequences. This survey aimed to assess self-reported oral hygiene practices, oral and general health events, and changes in physiological functions (including physical status, smell, taste, breathing, appetite, etc.) due to E-cigarette use among dental students. METHODS This online, multicounty survey involved undergraduate dental students from 20 dental schools across 11 different countries. The questionnaire included demographic characteristics, E-cigarette practices, self-reported complaints, and associated physiological changes due to E-cigarette smoking. Data were descriptively presented as frequencies and percentages. A Chi-square test was used to assess the potential associations between the study group and sub-groups with the different factors. Statistical analysis was performed using SPSS at P < 0.05. RESULTS Most respondents reported regular brushing of their teeth, whereas only 70% used additional oral hygiene aids. Reported frequencies of complaints ranged from as low as 3.3% for tongue inflammation to as high as 53.3% for headache, with significant differences between E-cigarette users and non-users. Compared to non-smokers, E-cigarette users reported significantly higher prevalence of dry mouth (33.1% vs. 23.4%; P < 0.001), black tongue (5.9% vs. 2.8%; P = 0.002), and heart palpitation (26.3%% vs. 22.8%; P = 0.001). Although two-thirds of the sample reported no change in their physiological functions, E-cigarette users reported significant improvement in their physiological functions compared to never smokers or tobacco users. CONCLUSION Dental students showed good oral hygiene practices, but E-cigarette users showed a higher prevalence of health complications.

In vitro evaluation of the effect of the electronic cigarette aerosol, Cannabis smoke, and conventional cigarette smoke on the properties of gingival fibroblasts/gingival mesenchymal stem cells. J Periodontal Res 2021; 57:104-114. [PMID: 34748642 DOI: 10.1111/jre.12943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 09/25/2021] [Accepted: 10/12/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVE The current study aimed to evaluate the effect of electronic cigarette (EC) aerosol, Cannabis, and conventional cigarettes smoke on gingival fibroblast/gingival mesenchymal stem cells' (GF/G-MSCs) of never smokers. MATERIAL AND METHODS Human GF/G-MSCs (n = 32) were isolated and characterized using light microscopy, flow cytometry, and multilineage differentiation ability. Following the application of aerosol/smoke extracts, GF/G-MSCs were evaluated for cellular proliferation; colony-forming units (CFU-F) ability; cellular viability (using the MTT assay); mitochondrial depolarization using JC-1 dye; and genes' expression of ATM, p21, Oct4, and Nanog. RESULTS Colony-forming units and viability (OD 450 nm) were significantly reduced upon exposure to Cannabis (mean ± SD; 5.5 ± 1.5; p < .00001, 0.47 ± 0.21; p < .05) and cigarettes smoke (2.3 ± 1.2 p < .00001, 0.59 ± 0.13, p < .05), while EC aerosol showed no significant reduction (10.8 ± 2.5; p = .05, 1.27 ± 0.47; p > .05) compared to the control group (14.3 ± 3, 1.33 ± 0.12). Significantly upregulated expression of ATM, Oct4, and Nanog (gene copies/GADPH) was noticed with Cannabis (1.5 ± 0.42, 0.82 ± 0.44, and 1.54 ± 0.52, respectively) and cigarettes smoke (1.52 ± 0.75, 0.7 ± 0.14, and 1.48 ± 0.79, respectively; p < .05), whereas EC aerosol caused no statistically significant upregulation of these genes compared to the control group (0.63 ± 0.1, 0.31 ± 0.12, and 0.64 ± 0.46, respectively; p > .05). The p21 gene was not significantly downregulated in EC aerosol (1.22 ± 0.46), Cannabis (0.71 ± 0.24), and cigarettes smokes (0.83 ± 0.54) compared to the control group (p = .053, analysis of variance). CONCLUSION Cannabis and cigarettes smoke induce DNA damage and cellular dedifferentiation and negatively affect the cellular proliferation and viability of GF/G-MSCs of never smokers, whereas EC aerosol showed a significantly lower impact on these properties.

Abstract
INTRODUCTION Universities are increasingly considering tobacco-free campus policies to help promote a healthy learning and working environment. We assessed attitudes of students, faculty, and staff, before and after the implementation of a tobacco-free campus policy at a large, urban university. We also examined individual factors associated with these attitudes. METHODS An independent panel design method was used to assess students, faculty and staff about their tobacco product use, attitudes towards tobacco policies, and support for cigarette and e-cigarette bans 3 months before and 7 months after a university-wide policy change to ban tobacco and e-cigarettes on campus. Survey participants before the policy change included 636 students and 1356 faculty/ staff. Survey participants after the policy change included 1000 students and 574 faculty/staff. We conducted separate multiple linear and logistic regression models for students and faculty/staff. RESULTS Attitudes towards tobacco-free campus policies did not improve for students, but did for faculty/staff. Support for bans of cigarettes and e-cigarettes on campus increased following the policy change among both students and faculty/staff. Students were more willing to ask their friends to stop vaping post-policy, but did not differ in their willingness to ask friends to stop smoking. Among the individual factors considered, gender and use of cigarettes and e-cigarettes were predictive of attitudes among both students and faculty/staff. Women were more likely to support and have more positive attitudes towards bans, while current tobacco product users were less likely to support tobacco product bans and have less positive attitudes towards tobacco policies. CONCLUSIONS Attitudes towards tobacco-free campus policies changed pre- to postpolicy among faculty/staff, but not among students. However, both students and faculty/staff were more supportive of tobacco product bans following the policy change. Individual factors associated with support and attitudes were identified.

Abstract
Methylenetetrahydrofolate reductase (MTHFR) polymorphism plays a fundamental role in susceptibility to various diseases, including cancers and autoimmune diseases. In the current study, we aimed to compare genotype and allele frequency variations of rs1801131, one of the most common variants found in the MTHFR gene, among Saudi smokers and non-smokers. We hypothesized that genetic variations of this gene are responsible for many diseases, particularly those caused by cigarette smoking (CS) such as pulmonary diseases, oral cancer and lung cancer. We performed a case-control study on a sample of 235 healthy smokers and 239 healthy non-smokers in Saudi Arabia. The rs1801131 SNP genotypes were determined using a genotyping assay and multiple in silico algorithmic software programs were used to identify the effects and structural functions of the rs1801131 (Glu429Ala) mutation. Using chi-squared tests, we found that, among smokers, TG and GG genotype carriers had 0.209-fold (OR = 0.209, P < 0.005) and 0.427-fold (OR = 0.427, P = 0.003) lower risks of CS-related disease compared to TT reference genotypes. In addition, this protective effect was observed in Saudi smokers independent of age, gender, types of smoking, duration, and average daily smoking consumption. Filling a research gap by exploring this topic in the Saudi population, the current findings indicate that genotype and allele distributions of MTHFR rs1801131 polymorphism present fundamental protective effects against the risk of CS-related disease. These findings should be verified in future studies with larger sample sizes, different ethnicities, and patients suffering from CS-related diseases, such as oral cancer and lung cancer.

Abstract
BACKGROUND The popularity and prevalence of electronic cigarette (EC) usage has continued to surge to 35 million worldwide, with one-half of users younger than 34 years. Despite emerging research suggesting deleterious oral health effects, the perceptions of EC users concerning oral health effects remain unknown. The purpose of this study was to explore knowledge, attitudes, and practices of young adults regarding the impact of EC use on oral health. METHODS A cross-sectional survey used a validated tool to investigate vaping and oral health knowledge, attitudes, and practices among a convenience sample of EC users (N = 220). Outcomes were analyzed using descriptive and inferential statistics. RESULTS People 18 through 24 years (N =168) indicated a lack of knowledge (mean [standard deviation {SD}], 2.9 [1.7]) and familiarity with oral health effects of vaping (mean [SD], 2.7 [1.7]). Participants expressed willingness to discuss oral health effects of vaping with dental care professionals (n = 111 [66%]), and most (n = 109 [65%]) would potentially reduce (30%) or quit (24%) if they believed it was harmful to their oral health. Participants 18 through 24 years were more likely to agree they would quit (n = 54 [68%]) than those 25 through 34 years (n = 36 [42%]; χ2 = 11.03; P = .004; φ = 0.26). Those who visit their dental care professional every 6 months (n = 82 [57%]) agreed they would quit vaping versus those who do not (n = 26 [37%]; χ2 = 9.84; P = .007; φ, 0.22). CONCLUSIONS Respondents reported low knowledge regarding the implications of vaping on oral health but expressed a willingness to discuss vaping with their dental care professionals. PRACTICAL IMPLICATIONS Most EC users are willing to accept guidance from dental care professionals regarding quitting use.

Abstract
BACKGROUND Smoking is a significant risk factor for periodontal disease and tooth loss, as shown in several clinical studies comparing smokers and nonsmokers. Although only a few longitudinal studies have assessed the outcome of periodontal disease after smoking cessation, they indicated that recovery after nonsurgical treatment was more successful in those who had quit smoking. As part of tobacco harm reduction strategies, substituting cigarettes with alternative, less harmful tobacco products is an approach complementary to cessation for smokers who would otherwise continue to smoke. The Tobacco Heating System (THS), developed by Philip Morris International (commercialized as IQOS), is part of the heat-not-burn product category. The IQOS device electrically heats tobacco instead of burning it, at much lower temperatures than cigarettes, thereby producing substantially lower levels of harmful and potentially harmful constituents, while providing the nicotine, taste, ritual, and a sensory experience that closely parallel those of cigarettes. Phillip Morris International has published the results from a broad clinical assessment program, which was established to scientifically substantiate the harm reduction potential of the THS among adult healthy smokers switching to the THS. The program is now progressing toward including adult smokers with smoking-related diseases. OBJECTIVE The goal of this study is to demonstrate favorable changes of periodontal endpoints in response to mechanical periodontal therapy in patients with generalized chronic periodontitis who completely switched to THS use compared with continued cigarette smoking. METHODS This is a randomized controlled two-arm parallel-group multicenter Japanese study conducted in patients with chronic generalized periodontitis who switch from cigarettes to THS compared with smokers continuing to smoke cigarettes for 6 months. The patients were treated with mechanical periodontal therapy as per standard of care in Japan. The primary objective of the study is to demonstrate the beneficial effect of switching to THS use compared with continued cigarette smoking on pocket depth (PD) reduction in all sites with an initial PD≥4 mm. The secondary objectives include evaluation of other periodontal parameters (eg, clinical attachment level or gingival inflammation) and overall oral health status upon switching to THS. Safety was monitored throughout the study. RESULTS In total, 172 subjects were randomized to the cigarette (n=86) or THS (n=86) groups, and all 172 completed the study. The conduct phase of the study is completed, while data cleaning and analyses are ongoing. CONCLUSIONS This study is the first to test a heat-not-burn tobacco product in smokers with an already established disease. The results should further strengthen the evidence that switching to THS can significantly reduce the risk of smoking-related diseases if favorable changes in the evolution of chronic generalized periodontitis after mechanical therapy are found when compared with continued cigarette smoking.

Abstract
INTRODUCTION The water pipe is a form of tobacco smoking that recently become very popular among youth in many countries all over the globe. AIM To highlight recent data collected through Global Youth Tobacco Survey (GYTS) in the Federation of Bosnia and Herzegovina (FBiH) 2019, related to knowledge, attitudes and behavior of school children and youth to water pipe consumption. METHODS The GYTS questionnaire for the Federation of BiH 2019 contained 60 multiple-choice questions. The GYTS 2019 in the Federation of BiH was conducted in a total of 73 of the 75 sampled primary and secondary schools with a school response rate of 97.3%. From the 6,972 sampled students a total of 6,415 participated as eligible students in grades 8-9 of primary and 1st grade of secondary school, with a response rate for students of 92.0%. RESULTS Survey findings show that almost half (44.1%) of the school children confirm ever smoking the water pipe, while Current smoking of water pipe is confirmed by 16.1% school children. CONCLUSION There is a substantial need for implementing of systematic and inter sectorial tobacco control measures that involves a water pipe as new public health challenge among youth.

Abstract
Use of electronic nicotine delivery systems (ENDS), such as electronic cigarettes (e-cigs), is increasing across the US population and is particularly troubling due to their adoption by adolescents, teens, and young adults. The industry’s marketing approach for these instruments of addiction has been to promote them as a safer alternative to tobacco, a behavioral choice supporting smoking cessation, and as the ‘cool’ appearance of vaping with flavored products (e.g. tutti frutti, bubble gum, and buttered popcorn etc.). Thus, there is a clear need to better document the health outcomes of e-cig use in the oral cavity of the addicted chronic user. There appears to be an array of environmental toxins in the vapors, including reactive aldehydes and carbonyls resulting from the heating elements action on fluid components, as well as from the composition of chemical flavoring agents. The chemistry of these systems shows that the released vapors from the e-cigs frequently contain levels of environmental toxins that considerably exceed federal occupational exposure limits. Additionally, the toxicants in the vapors appear to be retained in the host fluids/tissues at levels often approximating 90% of the levels in the e-cig vapors. These water-soluble reactive toxins can challenge the oral cavity constituents, potentially contributing to alterations in the autochthonous microbiome and host cells critical for maintaining oral homeostasis. This review updates the existing chemistry/environmental aspects of e-cigs, as well as providing an overview of the somewhat limited data on potential oral health effects that could occur across the lifetime of daily e-cig users.

Abstract
Objective: Cigarette tobacco smoking has been shown to cause cancer through different mechanisms that include epigenetic modulation of tumor-suppressor genes. In the present study, the association between global and MLH1 gene promoter methylation and waterpipe tobacco smoking was investigated. Materials and Methods: Blood lymphocytes and oral epithelium were sampled from 150 pure waterpipe smokers and 150 never-smokers from Jordan. Methylation assessment was performed using the methylation-specific PCR technique for MLH1 gene and ELISA for global DNA methylation. Results: Significant increases were shown in global DNA methylation as measured in blood lymphocytes (p < 0.01). In addition, increases in MLH1 gene promoter methylation among waterpipe smokers compared to nonsmokers (p < 0.001) in both oral epithelium and blood lymphocytes was also observed. In addition, strong correlation was found between LWDS-10J dependence score and magnitude of promoter specific methylation of MLH1 (r2 = 0.74-0.78, p < 0.001). Moreover, the percentage of methylated MLH1 promoter was not affected by age or gender (p > 0.05). Discussion and Conclusion: Collectively, the results indicate that waterpipe tobacco use is associated with epigenetic changes that might predispose users to lung and blood cancers. The results highlight the need for actions to discourage waterpipe smoking and can be used in cessation interventions that target this type of smoking.

Abstract
BACKGROUND While cigarette smoking has been considered the most relevant tobacco product worldwide, waterpipe tobacco smoking (WTS) has increased in prevalence globally and calls for more considerable attention now. However, little is known about WTS cessation knowledge and clinical practices among physicians, particularly in Lebanon. This study aims to examine the knowledge, barriers, and cessation practices of primary care practitioners towards WTS. METHODS A cross-sectional study where an anonymous self-reported questionnaire was completed by physicians attending the Annual Conference of the Lebanese Society of Family Medicine for family medicine physicians, general practitioners, and internists in Lebanon. RESULTS Out of 180 attendees, 105 primary care practitioners (PCPs) responded to the questionnaire. Only 38.1% of the physicians think similar techniques are used for the cessation of smoking of both cigarette and waterpipe. Similarly, 30.5% of the physicians believe that nicotine replacement therapy works in the cessation of waterpipe smoking. There was a statistically significant difference between the percentage of physicians who counsel for cigarette smoking and those who counsel for waterpipe smoking cessation (p = 0.005) where 30% of the physicians tend to counsel against cigarette smoking more than waterpipe smoking. CONCLUSIONS This study shows a difference in the attitude and behavior of PCPs towards cigarette and waterpipe smoking cessation. Moreover, there is a lack of knowledge about water pipe smoking cessation techniques. There is a great room for continued medical education to PCPs in their private practice to improve their knowledge.

Abstract
This paper is the second in a four-part series outlining treatment planning at periodontal reassessment. The first article focussed on the information that should be gathered at the reassessment appointment. Treatment can involve a range of non-surgical and surgical approaches. A variety of general, practical and local site factors can affect the choice of one option over another in choosing the most predictable treatment option. Residual periodontal probing depths can be associated with both systemic and local factors. This article (part 2) outlines systemic factors that need to be assessed when faced with residual periodontal probing depths.

Abstract
Studies evaluating the effects of narghile use on the periodontium present conflicting conclusions. This study aimed to compare the periodontal status of exclusive narghile smokers (ENSs, n = 74) to that of exclusive cigarette smokers (ECSs, n = 74). Males aged 20-40 years were recruited to participate in this comparative study. Information concerning oral health habits (number of yearly visits to the dentist, daily toothbrushing frequency) and tobacco exposure were obtained. Clinical measurements were performed on all the existing teeth, except the third molars. The number of remaining teeth and decayed/missing/filled teeth (DMFT) were noted. The plaque levels were recorded using the plaque index of Löe and Silness. The gingival index modified by Löe was used to evaluate gingival inflammation. Teeth mobility was measured using bidigital mobility. The probing pocket depth was measured using a periodontal probe. Periodontal disease was defined as the presence of at least 10 sites with a probing depth ≥5 mm. Student's t and chi-square tests were used to compare, respectively, the two groups' quantitative and qualitative data. The two groups were matched for quantities of used tobacco, age, daily toothbrushing frequency, teeth mobility, number of remaining teeth, plaque index, and DMFT. Compared to the ECS group, the ENS group had a significantly lower number of yearly visits to the dentist (mean ± SD: 0.2 ± 0.5 vs. 0.1 ± 0.2), lower probing pocket depth (mean ± SD: 2.33 ± 0.63 vs. 2.02 ± 0.80 mm), and gingival index (median [interquartile]: 0.46 [0.10-0.89] vs. 0.00 [0.00-0.50]), and it included significantly lower percentages of smokers with periodontal disease (24.3% vs. 9.5%). In conclusion, chronic exclusive narghile smoking has fewer adverse effects on the periodontium than chronic exclusive cigarette smoking.

Abstract
Cigarette smoke is widely regarded as a carcinogenic agent; thus, the incidence of relative neoplasms correlates to cigarette smoking (CS) on a global level. While CS is most commonly associated with carcinomas of the upper and lower respiratory tracts, studies have also associated CS with the pathogenesis of a variety of non-respiratory related neoplasms. The tobacco smoke emitted from cigarettes contains carcinogenic substances that can be harmful to the normal physiology of the human body. This study will elaborate on the incidence and etiology of carcinomas, as well as discuss, in detail, the role of tobacco in the pathogenesis of oral, esophageal, lung, gastric, pancreatic, renal, and bladder carcinomas.

Abstract
Hookah smoking is becoming a popular trend globally. Waterpipe smoking is the second most prevalent form of alternate tobacco products. The rapid increase in hookah use is because of the misconception prevalent in society that hookah smoking is less harmful than cigarette smoking. Smoking ban policies had given impetus of switching from cigarette smoking to alternate tobacco products like waterpipe. Hookah users regard hookah to be more socially acceptable, less stigmatizing with flavors and to alleviate cigarette craving symptoms. Newer basic science research on animal models and human cells has shown consistently mutagenic, oxidative, and inflammatory changes that could cause possible health effects of premalignant oral lesion and chronic diseases like atherosclerosis and chronic obstructive pulmonary disease. Studies on the chemistry of waterpipe smoke had shown alarming results with the smoke containing seven carcinogens, 39 central nervous system depressants, and 31 respiratory irritants. Enormous data exist showing waterpipe smoking causing various health effects. Hookah smoking effects on cardiovascular disease is additive with hookah containing a significant amount of nicotine, tar, and heavy metals causing both acute and chronic effects on the cardiovascular system. These effects include increased heart rate, blood pressure, prevalence of coronary heart disease, heart failure, ST-segment elevation myocardial ischemia, recurrent ischemia, and worse outcomes including mortality related to these diseases. The objectives of the review are to assess the factor associated with the increasing use of hookah, its health effects, options for hookah smoking cessation, and public health policy initiatives to mitigate waterpipe use.

Abstract
There is a paucity of evidence surrounding the potential detrimental effects of electronic nicotine delivery systems (ENDS) for both systemic and oral health. The effects of conventional cigarettes on the development of oral cancer are well known; however, the role of ENDS in oral carcinogenesis is yet to be elucidated. Furthermore, the exponential rise of the use of ENDS by the general public means that dental healthcare providers are more likely to encounter questions on their safety in the oral cavity, and on their effectiveness as a smoking cessation aid. Herein, we review the most up to date literature on the systemic and oral health complications of ENDS. Moreover, evidence-based recommendations on the use of ENDS as a smoking cessation tool within the dental setting are discussed.

Abstract
Flavors profiling in flavored hookah tobacco is an issue of increasing scrutiny for the health sector owing to its adverse effects on humans, especially being heated to produce smoke. This study aims at tackling the components involved in the flavored hookah tobacco from a chemical and biological point of view. Detecting individual flavor compounds, within a complex hookah tobacco matrix was accomplished using headspace solid phase microextraction (SPME). A total of 114 volatiles were identified in 13 flavored hookah tobacco products, with esters amounting for the major component up to 40%. Whereas oxygenated monoterpenes presented another major volatile class, contributing up to 23%, including (E)-anethole. Superheating flavored hookah tobacco at 190 °C resulted in the release of a mixture of phenol derivatives and polycyclic aromatic compounds that are indicative of coal tar, a major component produced during hookah tobacco usage with potential health hazards. This study provides the first comprehensive volatile profile of hookah tobacco products from different origins identifying chemical components involved in flavors. It is expected to serve as informative grounds for the better understanding of hookah tobacco production and usage. The information presented is also expected to raise awareness on the health risks of hookah tobacco smoking.

Abstract
OBJECTIVE The use of electronic cigarettes (ECIGs) has recently increased as an alternative to conventional smoking tobacco products. The literature is scarce on the effects of ECIGs on dental and oral structures. Therefore, the objective of this study was to observe whether ECIG aerosol could alter the color of dental enamel. MATERIALS AND METHODS Sixty-three bovine enamel specimens were randomly separated into groups (n = 7) and treated with aerosols with different e-liquid flavors (neutral, menthol, and tobacco) and nicotine content (0, 12, and 18 mg). The initial color assessment was performed using a spectrophotometer (Easy Shade-Vita). Dental enamel was exposed to 20 cycles of ECIG aerosol in a smoking machine, and the final color was measured. The color change was evaluated using ΔEab, ΔE00, and Whiteness Index (WID ) formulae. Differences in L* a* b* coordinates were calculated, and data were analyzed (two-way ANOVA, uncorrected Fisher's LSD post hoc test, α = 0.05). RESULTS Luminosity (ΔL) was reduced by aerosols with almost all levels of nicotine content and neutral and menthol flavors. Flavored e-liquids caused more color change (P < .05) according to ΔEab and ΔE00. ΔE values from both formulae exceeded the thresholds for perceptible visual alterations of color. WID increased after ECIGs exposure for menthol and tobacco and decreased for neutral flavors. CONCLUSIONS ECIG aerosol from e-liquids with different nicotine contents and flavors altered enamel color. Menthol and tobacco e-liquids may alter the enamel color decreasing the yellowness of the enamel compared to neutral e-liquid. CLINICAL SIGNIFICANCE Electronic cigarettes can cause perceptible changes in tooth color, altering dental esthetics.

Abstract
Cigarette smoking has been shown to be associated with changes in coagulation factors in the circulation and the subsequent thrombosis development. In this study, the impact of waterpipe smoking on the levels of fibrinogen, factor VII (FVII), and factor VIII (FVIII) was investigated. In addition, the effects of waterpipe smoking were compared to those of cigarette smoking and never smokers. A total of 80 male smokers (40 cigarette smokers and 40 waterpipe smokers) and 40 apparently healthy never smokers were recruited in the study. Both waterpipe smoking and cigarette smoking induced significant increases in the plasma levels of fibrinogen, factor VII, and factor VIII (p < 0.01). The magnitude of the increase in fibrinogen levels induced by waterpipe smoking was higher than that induced by cigarette smoking (p < 0.01), while similar increases were observed in other factors (p > 0.05). In addition, in the waterpipe group, the magnitude of the increase in fibrinogen and factor VIII was higher in the smokers with more than 3 years of use (p < 0.05). In conclusion, similar to cigarette smoking, waterpipe smoking modulates the levels of coagulation factors, suggesting its thrombotic potential.

Abstract
This retrospective convenient sample case-control study investigated the peri-implant soft-tissue inflammatory parameters and crestal bone loss (CBL) among narghile smokers (NS) (Group I) and nonsmoking controls (Group II). Demographic data were collected using a questionnaire. Peri-implant plaque index (PI), bleeding-on-probing (BOP) and pocket-depth (PD) were assessed; and peri-implant CBL was measured on standardized digital bite-wing radiographs. Sample-size was estimated and statistical analysis were done using Mann-Whitney U-test. Level of significance was set at p < .05. Seventy-two male individuals (35 in Group I and 37 in Group II) were included. The mean age of individuals in Groups I and II were 45.3 ± 5.2 and 42.6 ± 3.3 years, correspondingly. In Group 1, the duration and daily frequency of narghile smoking was 17.5 ± 1.6 years and 6.3 ± 0.5 times per day, respectively. The mean duration of each narghile smoking session was 28.5 ± 0.6 min. The mean peri-implant PI (p < .05), PD (p < .05) and mesial (p < .05) and distal (p < .05) CBL were statistically significantly higher among individuals in Group I compared with Group II. BOP was significantly higher in Group II than Group I (p < .05). Narghile smoking increases peri-implant soft-tissue inflammation and CBL.

Abstract
The main purpose of this study was to perform a meta-analysis to assess the interaction between smoking and nine genes (GSTM1, GSTT1, GSTP1, CYP1A1, NAT2, SULT1A1, hOGG1, XRCC1 and p53) on colorectal cancer, gastric cancer, liver cancer and oesophageal cancer. Published articles from the PubMed, ISI and EMBASE databases were retrieved. A total of 67 case-control studies or nested case-control studies were identified for the analysis. The pooled jodds ratio (OR) with 95% confidence interval (CI) was calculated using the random effect model. The overall study showed that the GSTM1 polymorphism was associated with the risk of the four digestive cancers among Asian population (OR 1.284, 95% CI: 1.122-1.470, p: 0). Subgroup analyses by cancer site showed that GSTM1 null genotype increased the gastric cancer risk in total population (OR 1.335, 95% CI: 1.145-1.556, p: 0). However, the association of GSTM1 null genotype with the oesophageal cancer risk was found in smokers (OR 1.382, 95% CI: 1.009-1.894, p:0.044), but not in non-smokers (OR 1.250, 95% CI: 0.826-1.891, p:0.290). Moreover, smokers with the CYP1A1 IIe462Val polymorphism were at an increased cancer risk in Asian population (OR=1.585, 95% CI 1.029-2.442, p: 0.037). None of the other gene-smoking interactions was observed in the above cancers. This meta-analysis reveals two potential gene-smoking interactions, one is between smoking and GSTM1 on oesophageal cancer, and the other is between smoking and CYP1A1 IIe462Val on the four cancers in Asian population. Future studies need to be conducted to verify the conclusions.

Abstract
Waterpipe smoking (WS), an emerging trend has major health concerns. It is prevalent worldwide as a recreational activity both indoors and outdoors. The aim of this review was to assess the impact of waterpipe smoke on the oral and respiratory system (oral cavity and pulmonary tissues). A number of studies have shown that periodontal health status is compromised in waterpipe smokers when compared with nonsmokers. Some studies have associated WS with oral premalignant and malignant lesions; however, due to the poor quality of these studies, the presented outcomes should be interpreted with caution. Although cigarette smoking has been considered as a potential risk factor for dental caries; there are no studies in indexed literature that have shown an association to exist between dental caries and WS. Inhaled waterpipe smoke imposes oxidative stress and inflammatory responses and compromises the ventilatory capacity of the lungs and may lead to an increased risk of decline in lung function. WS may cause oral and pulmonary diseases, such as periodontal disease and chronic obstructive airway disease, respectively. The association between WS and development of dental caries and oral pre-cancer and their relationships with chronic airways disease requires investigations. This review discusses the current evidence of waterpipe smoke effects on the oral health and respiratory system based on basic and clinical science and provides future directions for research and regulatory science on how WS can affect the oral cavity and the respiratory/pulmonary system.
