Dental treatment planning considerations for patients using cannabis: A case report

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.

Assessing dental student knowledge on cannabis and demonstrating the need for cannabis education

PURPOSE

The American Dental Association advocates for dentists' education on therapeutic and legal issues related to medical cannabis. It is important to understand current knowledge of cannabis and cannabinoids and to have a practical knowledge assessment instrument. This exploratory study is the first of its kind to assess dental students' knowledge of cannabis and aims to determine if there is a need for more instruction regarding cannabis in a dental school's curriculum.

METHODS

Predoctoral dental students at the University at Buffalo School of Dental Medicine were recruited to participate. A validated, anonymous 22-item online survey was adapted and administered to students in all 4 years of the dental program. There was a total of 56 knowledge points.

RESULTS

The average knowledge score was 21.6 points (SD = 5.2, range: 7-34), corresponding to 38.5% (SD = 9.2) of the answers correct. There were no overall differences in knowledge by gender, years in dental school, or by any reported source of formal education on cannabis. Those who reported doing their own research had higher knowledge scores. Most participants knew that there is an endogenous cannabinoid system (72.3%) and that Tetrahydrocannabinol (THC) is responsible for the "high" experienced with cannabis (76.6%). Most participants reported that they did not know the effective doses of THC (58.2%) and Cannabidiol (CBD) (66.7%); few provided an answer for THC (34%) or CBD (17%) in the acceptable range of 2-10 mg.

CONCLUSION

Dental students did not have adequate knowledge on cannabis and cannabinoids. Given the rapid expansion of cannabis legalization, additional efforts are needed to integrate cannabis topics into coursework and learning experiences.

Dental students' knowledge, attitudes, and perceptions about marijuana and its effects on patients' oral health

PURPOSE/OBJECTIVES

This article seeks to determine dental students' knowledge, attitudes, and perceptions toward patients' marijuana use and whether dental students would like additional marijuana education.

METHODS

Predoctoral dental students were invited in 2021 to complete a questionnaire regarding marijuana's oral health effects, their comfort discussing marijuana with patients and their interest in additional training.

RESULTS

Among participants (n = 206, 32.7% response rate), most were familiar with smoked, smokeless and edible methods, but only 39.3% were familiar with topical applications. Only 29.6% of preclinical and 32.2% of clinical Doctor of Dental Medicine students agreed that smoking marijuana was detrimental to one's health, compared to 64.6% of internationally trained Advanced Standing students. Significantly more clinical students (70.6%) could identify how often they treat patients having used marijuana compared to the estimates of preclinical students (36.7%), although 44.2% of all students indicated they were unsure. Not surprisingly, more preclinical students were uncomfortable treating patients during routine dental procedures (45.6% preclinical vs. 32.8% clinical) and when administering local anesthesia (45.6% preclinical vs. 38.8% clinical) due to not yet providing direct patient care. A majority of both preclinical (92.2%) and clinical (89.7%) students agreed they would benefit from more marijuana education. Clinical students preferred adding a brief introductory seminar while preclinical students preferred multiple lectures throughout the curriculum.

CONCLUSION

As states legalize medical and recreational marijuana use, dental schools need to evaluate marijuana education in their curriculum and develop resources so students can feel comfortable and confident in their ability to identify and safely treat patients who use marijuana.

Illegal drugs and periodontal conditions

In recent years, the practice of dentistry and periodontology has become complicated by several risk factors, including the treatment of an increasing number of patients with substance use disorder. This review presents an update in the current literature of the impact of illegal drug use on periodontal conditions and their possible effect as risk factors or indicators. The main illegal drugs that may have an impact on periodontal health and conditions are described, including their effect, medical manifestations, risks, and the overall effect on oral health and on the periodontium. Where available, data from epidemiologic studies are analyzed and summarized. The clinical management of periodontal patients using illegal drugs is reported in a comprehensive approach inclusive of the detection of illicit drug users, screening, interviewing and counseling, the referral to treatment, and the dental and periodontal management. With regard to the impact of illegal substance use on periodontal conditions, there is moderate evidence that regular long-term use of cannabis is a risk factor for periodontal disease, manifesting as a loss of periodontal attachment, deep pockets, recessions, and gingival enlargements. Limited evidence also shows that the use of cocaine can cause a series of gingival conditions that mostly presents as chemical induced-traumatic lesions (application of cocaine on the gingiva) or necrotizing ulcerative lesions. There is a scarcity of data regarding the impact of other drug use on periodontal health. There is evidence to suggest that regular long-term use of cannabis is a risk factor for periodontal disease and that the use of cocaine can cause a series of periodontal conditions. The dental treatment of subjects that use illegal substances is becoming more common in the daily clinical practice of periodontists and other dental clinicians. When the clinicians encounter such patients, it is essential to manage their addiction properly taking into consideration the impact of it on comprehensive dental treatment. Further studies and clinical observations are required to obtain sound and definitive information.

Oral Health Implications of Risky Behaviors in Adolescence

Adolescence is a time for new discoveries, which may lead teens to engage in impulsive behaviors. Although social media and the Internet have brought great benefits to the world, they can also have a negative influence on adolescents, facilitating their engagement in risky behaviors. Positive parenting and healthy friendships in adolescence have a protective effect against sensation-seeking behaviors. Dental practitioners also have a significant role in steering young patients toward healthy behaviors. They play an essential role in the early recognition, initiation of appropriate interventions, and referrals for treatment of youth at risk.

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.

Cannabis Use and Oral Health in a National Cohort of Adults

BACKGROUND

Cannabis use is common and increasing among adults. Evidence connects cannabis use to poor periodontal health, but few prospective studies exist of adults in the United States.

METHODS

This investigation examined associations between cannabis use and self-reported adverse oral health conditions among participants (N = 18,872) in the Population Assessment of Tobacco and Health (PATH) Study, a nationally representative cohort. Survey-weighted regression modeling estimated associations between cannabis use and seven self-reported measures of oral health status, adjusted for tobacco use and other disease risk factors.

RESULTS

Reporting past-30-days cannabis use in any of PATH Waves 1-3 was positively and statistically significantly associated at Wave 4 with multiple periodontal disease sequalae and with self-rated fair or poor overall oral health (adjusted odds ratio versus never-users: 1.75; 95% confidence interval: 1.52, 2.01).

CONCLUSIONS

These findings provide further evidence that cannabis use is an independent risk factor for poor oral health, although study limitations (self-reported outcomes, limited information on cannabis use frequency and modality) must be considered.

PRACTICAL IMPLICATIONS

Dental professionals should engage patients in clear, nonjudgmental dialogue about cannabis use to address oral health risks and avoid potential patient safety issues in care delivery. General recommendations for addressing cannabis use in dental practice are presented.
