Oral implications and dental management
It established that smoking marijuana is associated with xerostomia and because of the increased risk caries, 23 with a higher user has decayed, missingand filled teeth score compared with non-users.10 A study aimed to determine the effects of marijuana Smoking in the soft tissues of the mouth showed that 69.6% of xerostomia user experience soon after the administration cannabis.24 A further study assess the oral health of cannabis users in Switzerland show that cannabis users had significantly a higher amount of decay, more smooth surface caries, a lower frequency of daily oral hygiene, higher consumption of beverages cariogenic and less frequent regular dental attendance compared with controlstest group. 25 Interestingly, the clinical purified CBD products 'Epidolex' showed that saliva and salivary hypersecretion common adverse oral effects. 26 Oral soft tissue changes have been documented, with an increased incidence in marijuana and tobacco leukoedema smokers.25 same study reported the increasing prevalence of candidosis in users compared with non-users and postulated that it was a possibility the combination of poor denture hygiene, unsatisfactory nutritional factors and the use of marijuana contribute for the observed manifestations of candidosis. 25 A a review of the effects of oral cannabis users concluded that the increased prevalence of recreational marijuana use was associated with xerostomia, leukoedema and the increased prevalence and density of Candida albicans. 24 Smoking marijuana is also associated with increased risk of cancer of the mouth, such as hashish and marijuana smoke contains many carcinogens, including phenol, vinyl chloride and aromatic hydrocarbons and others.
Methamphetamine
Amphetamines classified as a psychostimulant drug, with the mode of action is thought to involve increased dopaminergic and noradrenergic neurotransmission in Amphetamines were registered for treatment CNS. 25 used in Australia including methylphenidate, dexamphetamine and lisdexamphetamine, used to treat narcolepsy and attention deficit hyperactivity disorder. 25 Methamphetamine ('crystal', 'speed' or 'ice') is amphetamines illegally produced and most abused and widely distributed illegally form of amphetamine, 27 because it is relatively cheap to produce and acquire 26 and have a relatively long duration action compared with other illicit drugs such as cocaine. 28, 29
Oral implications and dental management
people have articulated the appearance of their teeth as "blackened, stained, rotting, crumbling or falling apart27 with Hamamoto et al. 25 describe a typical location caries in chronic users generally involve the buccal cervical and smooth surfaces of teeth and interproximal surfaces of anterior teeth. Caries development tends to undergo a period of arrest and progression.
There are several reasons for the increase damage. Especially methamphetamine cause xerostomia as the direct action of the drug because of sympathetic stimulation of adrenergic receptors causes reduction and reduced salivary flow 30, 31, 32, 33 buffer ability. other factors contributing to rampant caries development including long duration of action MA equate with negative effects long-lasting drug, oral hygiene is not enough and dehydration because hyperactivity. Furthermore, two Prospective studies have shown that the Supreme Court has significantly increase the intake of soft drinks containing sugars and poor oral hygiene compared with the general population. 34, 35
Cocaine
Cocaine is a natural alkaloid with local anesthetic and psychoactive properties derived from the leaves of the coca bush Erythroxylon, a plant native to several countries in the South America 36, 37, 38 In the 1880s, cocaine was used as a local anesthetic for the eyes and otolaryngological surgeries 37, 38 and cocaine drops are still used today for topical anesthetic in eye, ear, nose and throat procedures.
Usually given intranasally by the 'grunt', pure cocaine is usually diluted by drug dealers with other substances such as mannitol, lactose, talc, caffeine, quinidine to increase their profits and chemical irritants make the product more dangerous for the cocaine user 38 can also be smoked , by converting cocaine 'Cracks', where it turns into a free base with mix it with ingredients such as sodium bicarbonate,free form the basis of highly addictive then heated and smoked, in which the 'crack' name comes from the popping sound made at heating.39 When cocaine snorting, time to peak effect is a few minutes after inhalation, taking place between 20-90 min and has a relatively short half-life of 1.5 hours compared to MA.
Cocaine is readily absorbed across the mucous membranes and have both local anesthetic properties by binding to the sodium channel, as well as a sympathomimetic properties by enhancing dopaminergic and noradrenergic neurotransmission in CNS.46 Securities cocaine euphoria is due to blocking the re-uptake and therefore subsequently increase dopamine levels. 40 Other effects from increased levels of neurotransmitters including dizziness, blurred vision, delirium, aggressive behavior and increased respiration rate. 37 Neurological degeneration has also been noted by chronic cocaine abuse, including deficits in cognition, attention deficits, emotional instability and depression 41 due to an increase in the sympathetic nervous system stimulation, other complications because it included hypertension and cardiac arrhythmias but also narrowing coronary arteries, thereby putting patients at risk of angina, hypertension and acute myocardial infarction. 37
Oral implications and dental management
Bruxism and temporomandibular joint discomfort and pain in the muscles around it are well-documented orofacial manifestations of cocaine use, the possibility of due to changes in dopaminergic neurotransmission. 42, 43, 44 attrition and erosion of tooth enamel and dentin is also a common finding, due to both grinding increase and a decrease in salivary pH caused by cocaine 45 pure cocaine (cocaine hydrochloride) has a pH of 4.5 is capable of the disintegration of the enamel and dentin when ingested either by direct placement in the oral cavity or with Cocaine is often placed nose administration 46 directly into the gingiva by the user to test the quality and the purity cocaine. 47
Oronasal perforations are again attributable to the vasoconstrictive actions of cocaine, resulting in reduced blood flow and subsequent ischaemia and necrosis of the orofacial tissues. 45 Dental treatment should be postponed for a minimum of 6-24 hours after the last administration Users cocaine. 48 Governance such as hypnotics often diazepam and zolpidem for the transition from euphoria. The influence of cocaine. It is well established that drugs also cause xerostomia, further compounding the risk of caries, oral infections and noncarious wear.
OPIOIDS
Heroin, also known as diethylmorphine, is a semi-synthetic opioid derived from morphine and together with pharmaceutical opioid abuse, contributing to the largest proportion of the global burden of disease of all drugs. 49, 50 This forbidden due to the high morbidity and mortality correlated with the injected use of heroin including endocarditis and hepatitis, but also another danger associated include overdose, spread of blood borne viruses and brand-related crime.Heroin use a serious public health problem. 51 Heroin is the most common opioid use among people injecting drugs,52 with a heroin addiction that affects nearly seven in 1000 adults in Australia.
Oral implications and dental management
heroin addiction is associated with xerostomia accompanied with hypoglycemia, 53 and the use of opioids chronically cause altered taste preferences of modulation of kappa and mu receptors which may be the reason why the cariogenic foods high user preference and beverages. 54, 55 Location caries the lesion has been described to be prevalent in the buccal, cervical and smooth surface and is often present prior to the start of methadone use 56, 57 given daily methadone syrup under the supervision of a pharmacist, which often sweetened with friendly for palatability, the latter of which may potentially contribute to the development of a study caries. oral health in patients on methadone program shows the user have worse oral health than non-users, the increased presence of residues roots, less often present teeth, xerostomia and increased prevalence of psychological problems accompanied by anxiety and other reports fear. 58, 59 have documented the rapid tooth decay with aggressive activity, extensive caries in patients with methadone maintenance therapy.
Conclusion
Illicit drug used is a significant public health problem, with dentists likely to encounter current and past users of various illicit drugs, underscoring the need for dentists to be aware of the oral implications associated with substance use disorder. Concomitant factors such as poly-drug use, including the use of alcohol and tobacco, as well as psychological, behavioural and social issues, compound the oral health of addicted persons and complicate dental management. The dentist is an indispensable member of the multidisciplinary team, since oral adverse effects are commonly associated with illicit drug use and are associated with a poorer quality of life for these individuals. Dentists should be aware of the rising misuse and diversion of pharmaceutical drugs and prescribe judiciously for a true therapeutic need with minimal quantities.
