As shown by the growing numbers of users attending the public drug addiction services, drug abuse is a phenomenon that is constantly spreading. It is important that dentists are aware of the oral problems linked to drug abuse. This study examines the general effects and oral implications of the illegal substances used by the majority of drug addicts. The main dental complications of cannabinoids are the increased incidence of squamous cell carcinomas of the oral cavity, the presence of xerostomia and severe gingivitis. Depending on how it is taken, cocaine may cause ischemic necrosis of the palate, inflammation, ulceration and gingival retraction, as well as an increased incidence of bruxism. Hallucinogens have few direct oral effects, but among these it is worth recalling xerostomia, increased bruxism and oral problems linked to malnutrition caused by ecstasy. Turning to the opioids, heroin is the drug primarily used by the majority of drug addicts. Its oral effects mainly take the form of dental decay, showing a particular form and extent linked either directly or indirectly to heroin use. This results in "typical" or "atypical" caries pathologies directly linked to the effects of heroin. Given the extent of this phenomenon, it is important that dentists are aware of the problems linked to drug abuse that they may have to treat.

Rampant caries is one of the hallmarks of chronic methamphetamine abuse. "Meth" is a potent central nervous system stimulant with physical and psychological effects similar to cocaine. It is the author's opinion that the caries associated with methamphetamine abuse is related to three risk factors: 1) xerostomia caused by the drug; 2) a subsequent increase in sugared soft drink consumption; and 3) lack of oral hygiene during extended periods of abuse. Patients in this risk group usually present for treatment due to severe pain. However, they may be reluctant to discuss their illegal drug habit. Anorexia may also be present. Treatment includes cessation of drug abuse, oral hygiene, restrictions on sugar intake, and daily fluoride supplementation. Such patients tend to exhibit poor compliance with treatment recommendations or fail to show for appointments.

Methadone is a synthetic opiate used in the treatment of opiate addiction. Various side-effects have been associated with the use of methadone. These include xerostomia, which can contribute to a high caries rate. The UK Regional Drug Misuse Database reported that around 118,500 drug users were receiving treatment from drug misuse agencies and GPs. The vast majority (87%) were receiving treatment from community specialist services. As many drug abusers have poor oral health, general dental practitioners are likely to encounter such individuals. It is essential therefore that dentists are aware of the potential difficulties that may be encountered when treating subjects receiving methadone. These problems may relate to previous drug abuse and to the effects of methadone therapy.

Tramadol, a centrally acting analgesic, consists of two enantiomers, both of which contribute to analgesic activity via different mechanisms. (+) Tramadol and the metabolite (+) -O- desmethyl-tramadol (M1) are agonists of the mu opioid receptor. (+) Tramadol also stimulates presinaptic release of serotonin and inhibits serotonin reuptake whereas (-) tramadol inhibits norepinephrine reuptake. Thus tramadol enhances inhibitory effects on pain transmission both by opioid and monoaminergic mechanisms. The complementary and synergistic actions of the two enantiomers improve the analgesic efficacy and tolerability profile of the racemate. Following oral administration the bioavailability of tramadol is high and with new slow release preparations twice daily administration enables effective pain control. The recommended maximum daily dose of tramadol is 400 mg/day. Tramadol is characterised by low plasma protein binding and quite extensive tissue distribution. Elimination is primarily by the hepatic route (metabolism by CYP2D6) and partly by the renal route. It is effective in different types of moderate-to-severe acute and chronic pain, including neuropathic pain, low back pain, osteoarthritis pain and breakthrough pain. It also causes fewer opioid-type adverse effects, e.g. nausea, drowsiness, vomiting, dry mouth and constipation. Although trials in literature demonstrate immune-stimulating effects of tramadol, there are also trials suggesting immunesuppressive effects that are lesser than morphine. Owing to its pharmacological properties, tramadol is more appropriate than NSAIDs for patients suffering from gastrointestinal and renal problems. Besides its proven clinical efficacy tramadol is a safe drug as respiratory depression, cardiovascular side effects, drug abuse and dependence are of minor clinical relevance, unlike some other opioids.

Oral health problems, among the most prevalent comorbidities related to addiction, require more attention by both clinicians and policy-makers. Our aims were to review oral complications associated with drugs, oral health care in addiction rehabilitation, health services available, and barriers against oral health promotion among addicts. Drug abuse is associated with serious oral health problems including generalized dental caries, periodontal diseases, mucosal dysplasia, xerostomia, bruxism, tooth wear, and tooth loss. Oral health care has positive effects in recovery from drug abuse: patients' need for pain control, destigmatization, and HIV transmission. Health care systems worldwide deliver services for addicts, but most lack oral health care programs. Barriers against oral health promotion among addicts include difficulty in accessing addicts as a target population, lack of appropriate settings and of valid assessment protocols for conducting oral health studies, and poor collaboration between dental and general health care sectors serving addicts. These interfere with an accurate picture of the situation. Moreover, lack of appropriate policies to improve access to dental services, lack of comprehensive knowledge of and interest among dental professionals in treating addicts, and low demand for non-emergency dental care affect provision of effective interventions. Management of drug addiction as a multi-organ disease requires a multidisciplinary approach. Health care programs usually lack oral health care elements. Published evidence on oral complications related to addiction emphasizes that regardless of these barriers, oral health care at various levels including education, prevention, and treatment should be integrated into general care services for addicts.
