A review and guide to drug‐associated oral adverse effects—Dental,salivary and neurosensory reactions. Part 1

Numerous adverse drug reactions (ADR) manifest in the oral cavity and orofacial region. Dentists and other health professionals commonly encounter and manage these adverse effects however, due to lack of awareness and training, they are not always recognised as being drug‐induced nor reported to pharmacovigilance agencies. The broad diversity and increasing number of medications for which dental pharmacovigilance is needed can be overwhelming for all health professionals. Thus, the aim of this review and guide was to outline the common medications associated with orofacial side effects so as to improve recognition, management and reporting of ADR. Adverse effects discussed in Part 1 include drug‐induced bruxism, tardive dyskinesia, hairy tongue, gingival enlargement, hypersalivation, xerostomia, tooth discolouration and taste disturbance.     

Interactions between sleep disorders and oral diseases

Dental sleep medicine is a rapidly growing field that is in close and direct interaction with sleep medicine and comprises many aspects of human health. As a result, dentists who encounter sleep health and sleep disorders may work with clinicians from many other disciplines and specialties. The main sleep and oral health issues that are covered in this review are obstructive sleep apnea, chronic mouth breathing, sleep‐related gastroesophageal reflux, and sleep bruxism. In addition, edentulism and its impact on sleep disorders are discussed. Improving sleep quality and sleep characteristics, oral health, and oral function involves both pathophysiology and disease management. The multiple interactions between oral health and sleep underscore the need for an interdisciplinary clinical team to manage oral health‐related sleep disorders that are commonly seen in dental practice.     

Oral manifestations of illicit drug use

The use of illicit and misuse of licit drugs is a global public health problem, with illicit drug use being responsible for 1.8% of the total disease burden in Australia in 2011. Oral adverse effects associated with illicit drug use are well‐established, with aggressive caries, periodontitis, bruxism, poor oral hygiene and general neglect documented. Other factors such as a high cariogenic diet and lifestyle, social and psychological factors compound the poorer oral health in illicit drug users. Literature has shown that the oral health‐related quality of life among injecting drug users is poorer compared with the Australian general population and the overall quality of life of addicted people correlates with caries experience. Thus, the role of the dentist is imperative in managing the oral health of these individuals. Given their widespread recreational use, it is likely that dental practitioners will encounter patients who are regular or past users of illicit drugs. The aim of this article is to describe the prevalence and mechanism of action of commonly used illicit drugs in Australia, including cannabis, methamphetamine, cocaine and heroin and to inform dentists about the common orofacial presentations of their side effects to help with patient management.     

A review of drug-induced oral reactions

Every drug can produce untoward consequences, even when used according to standard or recommended methods of administration. Adverse drug reactions can involve every organ and system of the body and are frequently mistaken for signs of underlying disease. Similarly, the mouth and associated structures can be affected by many drugs or chemicals. Good oral health, including salivary function, is very important in maintaining whole body health. Regarding different parts of the oral system, these reactions can be categorized to oral mucosa and tongue, periodontal tissues, dental structures, salivary glands, cleft lip and palate, muscular and neurological disorders, taste disturbances, drug-induced oral infection, and facial edema. In this article, the drugs that may cause adverse effects in the mouth and related structures are reviewed. The knowledge about drug-induced oral adverse effects helps health professionals to better diagnose oral disease, administer drugs, improve patient compliance during drug therapy, and may influence a more rational use of drugs.     

General and oral health implications of cannabis use

Cannabis, commonly known as marijuana, is the most frequently used illicit drug in Australia. Therefore, oral health care providers are likely to encounter patients who are regular users. An upward trend in cannabis use is occurring in Australia, with 40 per cent of the population aged 14 and above having used the drug. There are three main forms of cannabis: marijuana, hash and hash oil, all of which contain the main psychoactive constituent delta-9-tetrahydrocannabinol (THC). Cannabis is most commonly smoked, however it can be added to foods. THC from cannabis enters the bloodstream and exerts its effects on the body via interaction with endogenous receptors. Cannabis affects almost every system of the body, particularly the cardiovascular, respiratory and immune systems. It also has acute and chronic effects on the mental health of some users. Therefore, chronic abuse is a concern because of its negative effects on general physical and mental health. Cannabis abusers generally have poorer oral health than non-users, with an increased risk of dental caries and periodontal diseases. Cannabis smoke acts as a carcinogen and is associated with dysplastic changes and pre-malignant lesions within the oral mucosa. Users are also prone to oral infections, possibly due to the immunosuppressive effects. Dental treatment on patients intoxicated on cannabis can result in the patient experiencing acute anxiety, dysphoria and psychotic-like paranoiac thoughts. The use of local anaesthetic containing epinephrine may seriously prolong tachycardia already induced by an acute dose of cannabis. Oral health care providers should be aware of the diverse adverse effects of cannabis on general and oral health and incorporate questions about patients' patterns of use in the medical history.     

Consensus Report: 2nd European Workshop on Tobacco Use Prevention and Cessation for Oral Health Professionals

Tobacco use has been identified as a major risk factor for oral disorders such as cancer and periodontal disease. Tobacco use cessation (TUC) is associated with the potential for reversal of precancer, enhanced outcomes following periodontal treatment, and better periodontal status compared to patients who continue to smoke. Consequently, helping tobacco users to quit has become a part of both the responsibility of oral health professionals and the general practice of dentistry. TUC should consist of behavioural support, and if accompanied by pharmacotherapy, is more likely to be successful. It is widely accepted that appropriate compensation of TUC counselling would give oral health professionals greater incentives to provide these measures. Therefore, TUC‐related compensation should be made accessible to all dental professionals and be in appropriate relation to other therapeutic interventions. International and national associations for oral health professionals are urged to act as advocates to promote population, community and individual initiatives in support of tobacco use prevention and cessation (TUPAC) counselling, including integration in undergraduate and graduate dental curricula. In order to facilitate the adoption of TUPAC strategies by oral health professionals, we propose a level of care model which includes 1) basic care: brief interventions for all patients in the dental practice to identify tobacco users, assess readiness to quit, and request permission to re‐address at a subsequent visit, 2) intermediate care: interventions consisting of (brief) motivational interviewing sessions to build on readiness to quit, enlist resources to support change, and to include cessation medications, and 3) advanced care: intensive interventions to develop a detailed quit plan including the use of suitable pharmacotherapy. To ensure that the delivery of effective TUC becomes part of standard care, continuing education courses and updates should be implemented and offered to all oral health professionals on a regular basis.     

Stimulating the discussion on saliva substitutes: a clinical perspective

Xerostomia is a significant problem commonly faced by patients and oral health practitioners. There is no cure for this condition, which commonly manifests as a side effect of medications, head and neck irradiation and other systemic conditions, such as Sjögren's syndrome and type 2 diabetes. It may also arise idiopathically. Therefore, treatment is palliative and takes the form of oral lubricants and saliva substitutes which aim to reduce symptoms associated with xerostomia as well as prevent oral disease secondary to it. Recently there has been an expansion of the number and range of products available in Australia for the palliative management of xerostomia. It is imperative then that oral health professionals have a sound understanding of the advantages and disadvantages of using such products as patients tend to be well informed about new products which are commercially available. This article discusses some of the most commonly available products used for the symptomatic relief and preventive management of xerostomia. Amongst the plethora of products available to the patient suffering from xerostomia, no single product or product range adequately reproduces the properties of natural saliva and therefore consideration of patients' concerns, needs and oral health state should be taken into account when formulating a home care regime. With Australia's ageing population and its heavier reliance on medications and treatments which may induce xerostomia, oral health professionals are likely to encounter this condition more than ever before and therefore an understanding of xerostomia and its management is essential to patient care.     

Oral piercings and their dental implications: a mini review

Oral piercing has become common in young adults in recent years. Adolescents are characterized by a compulsive tendency to distinguish themselves from the rest; differences in clothes, hairstyle, or "decorative" details are used to this effect, based on highly-diverse criteria. Dental health-care professionals need to be aware of the procedures and risks involved with oral piercings and the social and psychological reasons that lead people to engage in this practice, regardless of the risks. The present article addresses oral mutilation practices, specifically from the oral health perspective, as it is of concern to dental professionals due to the health risks and oral complications associated with such practices. The various oral ornaments, piercing sites, and their implications, orally, as well as systemically, have been discussed.     

Systemic use of non‐biologics in orofacial diseases: 2. Purine synthesis inhibitors

Systemic non‐biological agents (NBAs) have been extensively used for immunosuppression in clinical medicine, often with considerable efficacy, although sometimes accompanied with adverse effects as with all medicines. With the advent of biological agents, all of which currently are restricted to systemic use, there is a rising need to identify which agents have the better therapeutic ratio. The NBAs include a range of agents, most especially the corticosteroids (corticosteroids). This article reviews the purine synthesis inhibitors (azathioprine and mycophenolate), which are currently the most commonly used systemically immunosuppressive agents in the management of orofacial mucocutaneous diseases. Subsequent articles discuss other corticosteroid‐sparing agents used in the management of orofacial disease, such as calcineurin inhibitors, and the cytotoxic and other immunomodulatory agents.     

Role and models for compensation of tobacco use prevention and cessation by oral health professionals

Appropriate compensation of tobacco use prevention and cessation (TUPAC) would give oral health professionals better incentives to provide TUPAC, which is considered part of their professional and ethical responsibility and improves quality of care. Barriers for compensation are that tobacco addiction is not recognised as a chronic disease but rather as a behavioural disorder or merely as a risk factor for other diseases. TUPAC‐related compensation should be available to oral health professionals, be in appropriate relation to other dental therapeutic interventions and should not be funded from existing oral health care budgets alone. We recommend modifying existing treatment and billing codes or creating new codes for TUPAC. Furthermore, we suggest a four‐staged model for TUPAC compensation. Stages 1 and 2 are basic care, stage 3 is intermediate care and stage 4 is advanced care. Proceeding from stage 1 to other stages may happen immediately or over many years. Stage 1: Identification and documentation of tobacco use is part of each patient's medical history and included into oral examination with no extra compensation. Stage 2: Brief intervention consists of a motivational interview and providing information about existing support. This stage should be coded/reimbursed as a short preventive intervention similar to other advice for oral care. Stage 3: Intermediate care consists of a motivational interview, assessment of tobacco dependency, informing about possible support and pharmacotherapy, if appropriate. This stage should be coded as preventive intervention similar to an oral hygiene instruction. Stage 4: Advanced care. Treatment codes should be created for advanced interventions by oral health professionals with adequate qualification. Interventions should follow established guidelines and use the most cost‐effective approaches.     

Sensory and motor deficits in the elderly: impact on oral health

Hearing, vision, orthopedic, and speech disorders are the most common impairments in the elderly. Older adults experience other sensory impairments such as olfactory and gustatory dysfunction, as well as oral motor problems including difficulty with mastication, speech, and swallowing. These disorders can directly affect oral health and can impair dental treatment. Therefore, it is imperative that dental health practitioners be cognizant of these conditions and aware of the impact these conditions and their treatments can have on oral health and function. Dental professionals may need to use different communication techniques for patients with vision or hearing losses. Accommodations in the dental office and by dental professionals will help older patients who have sensory and/or motor impairments to preserve their oral health and function and receive dental treatments in a safe and efficacious manner. This paper reviews the most common causes of sensory and motor impairments and their implications for oral health care with treatment modification guidelines for the older patient.

Hennequin‐Hoenderdos NL, Slot DE, Van der Weijden GA. Complications of oral and peri‐oral piercings: a summary of case reports. Abstract: Objective: To systemically search the literature for case reports concerning adverse effects associated with oral and peri‐oral piercings on oral health and/or general health. Material and methods: MEDLINE and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched up through 1 April 2010 to identify appropriate studies. Results: Independent screening of the titles and abstracts identified 1169 papers from MEDLINE and 73 papers from CENTRAL. Subsequently, 67 papers describing 83 cases were processed for data extraction. The case reports described complications in oral and general health. In this review, 96 complications were described for 83 cases. Of the 96 reported complications, 81% (n = 84) occurred in cases of tongue piercings, 20% (n = 21) in cases of lip piercings and 1% (n = 1) in cases of other oral piercings. In eight cases, subjects had two oral and/or peri‐oral piercings. Gingival recession was the most frequently described complication. Periodontitis and gingival recession were seen at the central mandibular incisors. Tooth fracture is mostly reported in subjects with tongue piercings. Conclusion: Among the case reports, there were complications like normal post‐operative swelling and localized inflammation but also more serious complication that may even have been life threatening. Also in the long term, piercing may be associated with gingival recession and tooth fracture. Therefore, oral and/or peri‐oral piercings are not without risks. Patients considering a piercing should be made aware of this. Those patients wearing a piercing should be screened by a dental professional for possible complications on a regular basis.     

Oral innate immunity in HIV infection in HAART era

Oral innate immunity, an important component in host defense and immune surveillance in the oral cavity, plays a crucial role in the regulation of oral health. As part of the innate immune system, epithelial cells lining oral mucosal surfaces not only provide a physical barrier but also produce different antimicrobial peptides, including human β‐defensins (hBDs), secretory leukocyte protease inhibitor (SLPI), and various cytokines. These innate immune mediators help in maintaining oral homeostasis. When they are impaired either by local or systemic causes, various oral infections and malignancies may be developed. Human immunodeficiency virus (HIV) infection and other co‐infections appear to have both direct and indirect effects on systemic and local innate immunity leading to the development of oral opportunistic infections and malignancies. Highly active antiretroviral therapy (HAART), the standard treatment of HIV infection, contributed to a global reduction of HIV‐associated oral lesions. However, prolonged use of HAART may lead to adverse effects on the oral innate immunity resulting in the relapse of oral lesions. This review article focused on the roles of oral innate immunity in HIV infection in HAART era. The following five key questions were addressed: (i) What are the roles of oral innate immunity in health and disease?, (ii) What are the effects of HIV infection on oral innate immunity?, (iii) What are the roles of oral innate immunity against other co‐infections?, (iv) What are the effects of HAART on oral innate immunity?, and (v) Is oral innate immunity enhanced by HAART?     

Increasing popularity of waterpipe tobacco smoking and electronic cigarette use: Implications for oral healthcare

Cigarette smoking increases the risk of developing several systemic conditions including cancer, cardiovascular and pulmonary diseases. Cigarette smoking is also detrimental to oral health as it increases the incidence and severity of oral cancer, periodontal diseases and peri‐implantitis, as well as impacting negatively on the dental patients' response to therapy. Therefore, consideration of smoking behavior and recommendation of smoking cessation are important parts of dental treatment planning. However, cigarettes are no longer the most popular form of tobacco use among adolescents in the United States and globally. In recent years, tobacco smoking using a waterpipe (“hookah,” “shisha”) and use of electronic cigarettes (ECIGs) has increased significantly. Thus, dental clinicians likely will treat more patients who are waterpipe and/or ECIG users. Yet, the literature on the health effects of waterpipe and ECIGs use is sparse. Both waterpipe and ECIGs deliver the dependence‐producing drug nicotine. Waterpipe tobacco smoking has been associated with periodontitis, dry socket, premalignant lesions, and oral and esophageal cancer. The health effects of long‐term ECIG use are unknown. The purpose of this review is to inform healthcare professionals about waterpipes and ECIGs, highlight emerging evidence on the biological effects of these increasingly popular tobacco products, and introduce perspectives for dental patient management and future research.     

A literature review of aesthetic perceptions of dental fluorosis and relationships with psychosocial aspects/oral health‐related quality of life

Chankanka O, Levy SM, Warren JJ, Chalmers JM. A literature review of aesthetic perceptions of dental fluorosis and relationships with psychosocial aspects/oral health‐related quality of life. Community Dent Oral Epidemiol 2010. © 2009 John Wiley & Sons A/S Abstract – Aesthetic perceptions and oral health‐related quality of life concerning dental fluorosis have been assessed in several studies during the past two decades. However, no comprehensive review article summarizing the studies investigating this issue has been published. Objective: To assess the relationships between perceptions of dental appearance/oral health‐related quality of life (OHRQoL) and dental fluorosis. Methods: The PubMed database was searched using the Medical Subject Headings (MeSH) for English‐language studies from 1985 to March 2009. Thirty‐five articles qualified for inclusion and then were classified into three categories based on the type of study approach: (i) respondent review of photographs and assessment concerning satisfaction/acceptance, (ii) respondent assessment of study subject’s teeth concerning satisfaction/acceptance, and (iii) respondent assessments of the psychosocial/OHRQoL impact. Results: There were varied results from earlier studies focused on satisfaction/acceptance of very mild to mild fluorosis. More recent studies with methodological improvements to assess impact on quality of life clearly showed that mild fluorosis was not a concern. Furthermore, mild fluorosis was sometimes associated with improved OHRQoL. Severe fluorosis was consistently reported to have negative effects on OHRQoL. Conclusion: Because dental fluorosis in the United States and other nations without high levels of naturally‐occurring fluoride is mild or very mild, with little impact on OHRQoL, dental professionals should emphasize the appropriate use of fluorides for caries prevention and preventing moderate/severe fluorosis.     

Risk factors for impaired oral health among 18‐ to 34‐year‐old Australians

Objectives: The objective of this study was to determine risk factors for a summary measure of oral health impairment among 18‐ to 34‐year‐olds in Australia. Methods: Data were from Australia's National Survey of Adult Oral Health, a representative survey that utilized a three‐stage, stratified, clustered sampling design. Oral health impairment was defined as reported experience of toothache, poor dental appearance, or food avoidance in the last 12 months. Multivariate Poisson regression models were used to evaluate effects of sociodemographic characteristics, self‐perceived oral health, dental service utilization, and clinical oral disease indicators on oral health impairments. Effects were quantified as prevalence ratios (PR). Results: The estimated percent of 18‐ to 34‐year‐olds with oral health impairment was 42.4 [95 percent confidence interval (CI) 37.7‐47.2]. In the multivariate model, oral health impairment was associated with untreated dental decay (PR 1.38, 95 percent CI 1.13‐1.68) and presence of periodontal pockets 4 mm+ (PR 1.29, 95 percent CI 1.03‐1.61). In addition to those clinical indicators, greater prevalence of oral health impairment was associated with trouble paying a $100 dental bill (PR 1.37, 95 percent CI 1.12‐1.68), usually visiting a dentist because of a dental problem (PR 1.46, 95 percent CI 1.15‐1.86), reported cost barriers to dental care (PR 1.46, 95 percent CI 1.16‐1.85), and dental fear (PR 1.43, 95 percent CI 1.18‐1.73). Conclusions: Oral health impairment was highly prevalent in this population. The findings suggest that treatment of dental disease, reduction of financial barriers to dental care, and control of dental fear are needed to reduce oral health impairment among Australian young adults.     

A functional natural dentition for all – and for life? The oral healthcare system needs revision

The cost of dental care adds to the costs of the already overburdened health sector. Do we – as patients and as society –receive oral health care that is both aligned with the actual disease experience and also, critically based on up‐to‐date scientific knowledge about the major oral diseases? In many places, the practice of dentistry reflects a response to disease patterns that once existed and is based on diagnostic and therapeutic approaches that are no longer valid. Instead, a new cadre of dental professionals is needed, one that is capable of meeting the actual health needs of our populations. This cadre should ensure that patients maintain a functioning dentition from cradle to grave based on cost‐effective disease control principles. There is an urgent need to: (i) reconsider the roles of the different oral health cadres involved in the provision of oral health care; (ii) integrate oral health into general healthcare services; and (iii) restructure the training of oral health personnel. We advocate a radical reform of the oral healthcare system involving the training of two new types of professionals integrated with the general healthcare system: The oral healthcare provider – a highly skilled professional specialised in the diagnosis and control of oral diseases and with a profound understanding of oral health as part of general health – and the oral clinical specialist – whose role is the provision of advanced oral rehabilitation, able also to treat people with complex chronic diseases and multiple medications.     

Eating Disorders: Screening in the Dental Office

BackgroundEating disorders are serious illnesses that often are not detected by health care professionals. The author presents techniques that the oral health care professional (OHCP) can use to screen at-risk patients for eating disorders during routine preventive care appointments.ConclusionsOHCPs often are the first health care professionals to encounter patients with undiagnosed eating disorders. Because early detection of eating disorders is challenging, screening tools can be helpful. Early detection of eating disorders, with appropriate referral, is associated with fewer dental and systemic adverse effects and a more favorable prognosis.Clinical ImplicationsOHCPs are in an ideal position to screen patients for eating disorders. They can accomplish this via a valid, reliable, brief questionnaire and careful patient assessment.     

Oral health care patterns and the history of miscarriage

Objective: Oral infections can trigger the production of pro‐inflammatory mediators that may be risk factors for miscarriage. We investigated whether oral health care patterns that may promote or alleviate oral inflammation were associated with the history of miscarriage in 328 all‐Caucasian women. Materials and methods: Of 328 women in this cross‐sectional cohort, 74 had history of miscarriage (HMC). Medical, dental and sociodemographic data were collected through clinical examinations, medical record searches and structured questionnaires. Results: The multivariate regression analyses indicated that urgency‐based dental treatment demonstrated a significant association [odds ratio (OR) = 2.54; 95% confidence interval (CI): 1.21–5.37; P = 0.01] and preventive dental treatment demonstrated a marginally significant inverse association (OR = 0.53; CI: 0.26–1.06; P = 0.07) with HMC. Self‐rated poor oral health had a non‐significant positive association with HMC (OR 1.60; CI: 0.88–2.90). Conclusion: Our results provide sufficient evidence for hypothesis generation to test whether other precise measures of oral inflammation are associated with adverse birth outcomes.
