The effect of tobacco and marijuana use on dental health status in Nevada adolescents: a trend analysis

Cannabis Uses in Dentistry: A Bibliometric Analysis

Background: This bibliometric review seeks to understand metrics of papers, authors, journals, and universities, about the benefits of the therapeutic application of Cannabis sativa (CS), as well as the most harmful effects associated to its use. Methods: The main search strategy applied to the topic was conducted in Web Of Science Core Collection on February 2024. A crossmatch of the number of citations was performed in Scopus and Google Scholar. The analyses were carried out in VOSviewer and Altmetric for PubMed and Google Scholar. Results: Of a total of 196 records, 53 articles were included for analysis. There were 25 publications on either therapeutic or harmful effects. In the ranking of subjects, those of greatest interest were general oral health and periodontics, with 53% of the total. The most cited paper was authored by Thomson et al. (2008) with 85 citations, allowing the University of Otago to be the most cited. Although JAMA was the most cited journal, in the dental field this corresponded to the Journal of Clinical Periodontology. In relation to the distribution by country, the United States received the largest number of citations and New Zealand second. Related to dentistry, in the cluster analysis, keywords more occurrent were "periodontal disease" and "periodontitis". Conclusions: In the past 4 years, there has been a superlative growth in CS papers related to oral health effects. This growth follows the social and political events related to CS legalization in some countries and reveals that the use of CS in dentistry is an emerging research field.

The Effect of Marijuana-Smoking on Dental Caries Experience

OBJECTIVE

This cross-sectional study aims to examine the effect of marijuana-smoking on dental caries experience and to explore the potential combined effects of tobacco and marijuana cigarette-smoking.

METHODS

We used data from the 2011-2014 National Health and Nutrition Examination Survey (NHANES). We examined demographics, tobacco- and marijuana-smoking, dental examination, and dietary intake. Caries was measured as decayed, missing, filled teeth (DMFT). Data analysis included univariate, bivariate analyses, and linear regression model (LRM) to examine the association between marijuana-smoking and DMFT.

RESULTS

Mean DMFT score was lowest for nonsmokers (8.72) and highest for current marijuana smokers (9.87) (P < .0001); however, LRM results revealed that marijuana-smoking was not associated with caries. Adjusted DMFT was the highest for current tobacco and former marijuana smokers (β estimate = 1.18; 95% CI, -0.27 to 2.62), but the relationship was not statistically significant.

CONCLUSIONS

After controlling for potential confounders, there was no significant association between marijuana-smoking and dental caries experience. However, when marijuana and tobacco were smoked concurrently, there was a notable increase in DMFT, although the difference was not statistically significant. Future research should be directed towards exploring the effects of different forms of marijuana consumption, such as edibles and drinkables, on caries development. Health promotion programmes should be aimed at educating the public regarding the combined health impacts of smoking both marijuana and tobacco, considering the potential heightened caries risk.

Oral health status among recreational cannabis (marijuana and hashish) users in the USA: A NHANES-based cross-sectional study

Background

As of November 2023, twenty-four states, two territories, and DC have legalized marijuana for non-medical use, leading to concerns about its potential oral health effects. This study investigated the association between marijuana use and clinical dental outcomes among adults in the US.

Methods

We analyzed data from the National Health and Nutrition Examination Survey (NHANES) from 2015 to 2018 using a cross-sectional survey of non-institutionalized US civilians. Marijuana use was assessed among 18-59-year-old adults and categorized as never, former, or current frequent use. The dental outcomes included the prevalence of untreated coronal caries, root caries, and missing teeth. We employed logistic and negative binomial regressions to assess the crude and adjusted associations between marijuana use, dental caries, and tooth loss.

Results

Of the 6,424 participants, 13.85% of US adults aged 18-59 years were current frequent marijuana users (21.67 million), with the highest prevalence among 18-29-year-olds (21.31%), males (17.54%), and non-Hispanic Black individuals (21.31%). Frequent marijuana users showed the highest prevalence of untreated coronal caries (33.4%). Before adjusting for socioeconomic confounders, current frequent marijuana users had 1.76 times higher odds of having teeth with coronal caries, whereas former frequent users had 1.47 times higher odds. However, the associations between marijuana use and all dental outcomes were attenuated after adjusting for socioeconomic confounders, tobacco use, and access to dental care.

Conclusion

Although marijuana use was associated with worse dental health, socioeconomic factors, tobacco use, and access to dental care were more significant contributors to the prevalence of untreated dental caries and missing teeth than marijuana use alone.

Associations between Oral Health and Cannabis Use among Adolescents and Young Adults: Implications for Orthodontists

Cannabis use is prevalent among adolescents and young adults in the US. Virtually all modes of cannabis consumption involve the oral cavity, and previous studies have linked cannabis use with poorer oral health. We sought to identify associations between cannabis use and various oral health outcomes and behaviors among individuals 12-25 years of age, and to discuss implications for orthodontists who largely interact with this age group over an extended period of treatment time. We examined data from patient electronic health records (N = 14,657) obtained between 2015 and 2021. Associations between lifetime and current self-reported cannabis use and several oral health outcomes or related behaviors that reflect periodontal health, caries status, oral lesions, and physical integrity of tooth structure and restorations were examined in a bivariable and multivariable manner, controlling for patient age, sex, and self-reported tobacco and alcohol use. Reporting lifetime cannabis use was associated with higher risk for having oral lesions (aPR = 1.41, 95% CI: 1.07-1.85), bruxism (aPR = 1.31, 95% CI: 1.09-1.58), and frequent consumption of sugary beverages and snacks (aPR = 1.27, 95% CI: 1.12-1.41). Reporting current cannabis use was associated with higher risk for oral lesions (aPR = 1.45, 95% CI: 1.03-2.06) and frequent consumption of sugary beverages and snacks (aPR = 1.26, 95% CI: 1.07-1.48). Cannabis users aged 12-25 are at increased risk for bruxism, oral lesions, and frequent consumption of sugary beverages and snacks. Orthodontists and other dental professionals should probe for drug use and be cognizant of increased risk for oral health problems in patients that report actively using cannabis.

Cannabinoids Drugs and Oral Health-From Recreational Side-Effects to Medicinal Purposes: A Systematic Review

Background: marijuana, the common name for cannabis sativa preparations, is one of the most consumed drug all over the world, both at therapeutical and recreational levels. With the legalization of medical uses of cannabis in many countries, and even its recreational use in most of these, the prevalence of marijuana use has markedly risen over the last decade. At the same time, there is also a higher prevalence in the health concerns related to cannabis use and abuse. Thus, it is mandatory for oral healthcare operators to know and deal with the consequences and effects of cannabis use on oral cavity health. This review will briefly summarize the components of cannabis and the endocannabinoid system, as well as the cellular and molecular mechanisms of biological cannabis action in human cells and biologic activities on tissues. We will also look into oropharyngeal tissue expression of cannabinoid receptors, together with a putative association of cannabis to several oral diseases. Therefore, this review will elaborate the basic biology and physiology of cannabinoids in human oral tissues with the aim of providing a better comprehension of the effects of its use and abuse on oral health, in order to include cannabinoid usage into dental patient health records as well as good medicinal practice. Methods: the paper selection was performed by PubMed/Medline and EMBASE electronic databases, and reported according to the PRISMA guidelines. The scientific products were included for qualitative analysis. Results: the paper search screened a total of 276 papers. After the initial screening and the eligibility assessment, a total of 32 articles were considered for the qualitative analysis. Conclusions: today, cannabis consumption has been correlated to a higher risk of gingival and periodontal disease, oral infection and cancer of the oral cavity, while the physico-chemical activity has not been completely clarified. Further investigations are necessary to evaluate a therapeutic efficacy of this class of drugs for the promising treatment of several different diseases of the salivary glands and oral diseases.

Association of marijuana use with oral HPV infection and periodontitis among Hispanic adults: Implications for oral cancer prevention

BACKGROUND

Despite limited data, research suggests that marijuana use is associated with oral HPV infection and periodontitis, two potential oropharyngeal cancer risk factors. We assessed these associations in a Hispanic adult population in Puerto Rico.

METHODS

A cross-sectional study of 735 adults assessed marijuana use, determined through an audio computer-assisted self-interview, and periodontitis and self-collection of oral HPV samples following the National Health and Nutrition Examination Survey methodology. The Centers of Disease Control and Prevention/American Academy of Periodontology definition was used for periodontitis. HPV typing was performed using polymerase chain reaction with modified L1 consensus primers (MY09/MY11).

RESULTS

26.5% of adults reported lifetime use of marijuana, 2.7% were frequent users (lifetime use ≥ 26 times, past year use ≥ 6 times, and past 30-day use ≥2 times), 5.7% had oral HPV infection, and 20.1% had severe periodontitis. The multivariate logistic regression analysis showed that frequent marijuana users were more likely to have severe periodontitis (OR = (2.93, 95%: 1.08-7.96)) than never/once lifetime users after adjusting for age, sex, healthcare coverage, smoking, binge drinking, number of oral sex partners, and oral HPV infection. However, frequent marijuana use was not associated with oral HPV infection.

CONCLUSION

Marijuana use was associated with periodontitis, but not with oral HPV infection. Further evaluation of the role of marijuana use in oral HPV infection and periodontitis may inform novel preventive public health strategies, as marijuana users could be at increased risk of oral cancer.

Oral health in transition: The Hadza foragers of Tanzania

Conventional wisdom holds that a decline in oral health accompanies the transition from hunting and gathering to agriculture, given increased consumption of carbohydrates. This widely touted example of the mismatch between our biology and modern lifestyle has been intuited largely from the bioarchaeological record of the Neolithic Revolution in the New World. Recent studies of other populations have, however, challenged the universality of this assertion. Here, we present the first comprehensive study of oral health among a living population in transition from the bush to village life, the Hadza hunter-gatherers of Tanzania, to test the hypothesis that the shift from foraging to farming, or agricultural intensification, inevitably leads to increased periodontal disease, caries, and orthodontic disorders. Our results showed that women living in villages consuming a mostly agricultural diet exhibited more caries and periodontal disease than those living in the bush consuming a mostly wild-food diet. Furthermore, men living in the bush consuming mostly a wild-food diet had more than those living in the village consuming a mostly agricultural diet. These findings are explained by the high incidence of maize consumption in village settings, along with previously recognized variation in rate of caries between men and women. The unexpected discovery of high caries incidences for men in the bush is likely explained by heavy reliance on honey, and perhaps differential access to tobacco and marijuana. These data support the notions that mechanisms of cariogenesis are multifactorial and that the relationships between oral health and the shift from a predominantly wild-food diet to one dominated by cultigens are nuanced.

Management of cannabis-induced periodontitis via resective surgical therapy: A clinical report

BACKGROUND AND OVERVIEW

There is a lack of clinical research on the potential effect of cannabis use on the periodontium as well as its effect on treatment outcomes. The aim of this case report is to illustrate the clinical presentation of periodontal disease in a young woman who was a chronic cannabis user, as well as successful treatment involving motivating the patient to quit cannabis use and undergo nonsurgical and surgical therapy.

CASE DESCRIPTION

A 23-year-old woman sought care at the dental clinic for periodontal treatment. During a review of her medical history, the patient reported using cannabis frequently during a 3-year period, which coincided with the occurrence of gingival inflammation. She used cannabis in the form of cigarettes that were placed at the mandibular anterior region of her mouth for prolonged periods. Localized prominent papillary and marginal gingival enlargement of the anterior mandible were present. The mandibular anterior teeth showed localized severe chronic periodontitis. The clinicians informed the patient about the potentially detrimental consequences of continued cannabis use; she was encouraged to quit, which she did. The clinicians performed nonsurgical therapy (scaling and root planing) and osseous surgery. The treatment outcome was evaluated over 6 months; improved radiographic and clinical results were observed throughout the follow-up period.

CONCLUSIONS AND PRACTICAL IMPLICATIONS

Substantial availability and usage of cannabis, specifically among young adults, requires dentists to be vigilant about clinical indications of cannabis use and to provide appropriate treatments. Behavioral modification, nonsurgical therapy, and surgical therapy offer the potential for successful management of cannabis-related periodontitis.

Dental clearance prior to elective arthroplasty may not be needed for everyone

We investigated the prevalence and risk factors for preoperative dental clearance failure in joint arthroplasty patients. Over a 5-month period, all patients scheduling total joint arthroplasty completed a dental questionnaire. Data collected included demographics, medical and dental history, dental hygiene practices, frequency of dental care, and results of dental clearance. Of the 300 patients, 35 (12%) failed dental clearance. Risk factors included tobacco use, poor flossing habits, history of tooth extraction, age, narcotic use, and lack of a dentist visit within 12 months. Of 189 patients who lacked the 3 least prevalent risk factors (tobacco use, narcotic use, no dental visit within 12 months), 11 (6%) failed dental clearance. Selective dental clearance based on patient risk stratification may be a reasonable approach.
