Abstract
Background Brazil has a larger number of adolescent offenders, but studies evaluating their oral health are still limited. Objective Assess the association between salivary flow and caries experience in youngsters deprived of liberty. Methodology Sixty-eight male adolescents in conflict with the law, aged between 15 and 19 years, from a Socio-Educational Assistance Center in Brazil participated in the present study. They answered a structured questionnaire, and oral examination was performed by the Decayed, Missing, and Filled Teeth (DMFT) index. The salivary flow rate was obtained using the mechanically stimulated total saliva method. Adjusted Poisson regression was used for the association with total DMFT and its decayed component, using the salivary flow (continuous fashion) or the hyposalivation (≤1 ml/min) as independent variables. Results Participants were divided into two groups, those who did not have any decayed teeth at the moment of the examination (n = 39) and those who had at least one decayed tooth (n = 29). Moreover, two groups were formed based on the DMFT: those who had DMFT = 0 (n = 20) and those who had DMFT≥1 (n = 48). In the multivariate analysis, hyposalivation was associated with DMFT≥1 (p = 0.048), but when the salivary flow was included, no significant association with DMFT index was identified (p = 0.178). Conversely, the presence of at least one decayed tooth was significantly associated with the salivary flow (p = 0.004), but not with hyposalivation (p = 0.091). Conclusions Institutionalized adolescents who present hyposalivation or low salivary flow are associated with DMFT≥1 index or presence of at least one decayed tooth, respectively.

Abstract
OBJECTIVE To assess the prevalence and associated factors of self-reported halitosis in institutionalized adolescents in a city in southern Brazil. METHODS This cross-sectional study involved male institutionalized adolescents, aged 15-19 years old, at the Socio-Educational Assistance Center in the city of Passo Fundo, Brazil. Data collection was performed by a research team composed of two interviewers, two clinical examiners of oral health and two examiners of salivary flow. A structured questionnaire was applied, which included demographical, socioeconomical, general health behaviour, presence of health problems and oral health self-perception variables. Decayed, Missing, Filled Index was used for the clinical examination. The salivary flow collection was performed using the mechanically stimulated total saliva method, in which only the liquid component was measured. RESULTS The prevalence of self-reported halitosis in this sample was 51.5% (n = 35). In the final multivariate analysis, halitosis was significantly associated with the non-white racial group (prevalence ratio [RP]:1.703; 95% confidence interval [95%CI]:1.101-2.634), use of crack (RP:1.857; 95%CI:1.270-2.714) and number of decayed teeth (PR: 1.123; 95%CI:1.008-1.252). The use of alcohol and access to dental care in the last 12 months were not significantly associated with self-reported halitosis. CONCLUSION It was concluded that non-white and crack-user youngsters had a high occurrence of self-reported halitosis. Higher rates of dental caries are also associated with halitosis.

Oral Enrichment of Streptococcus and its Role in Systemic Inflammation Related to Monocyte Activation in Humans with Cocaine Use Disorder. J Neuroimmune Pharmacol 2022; 17:305-317. [PMID: 34448131 PMCID: PMC8881519 DOI: 10.1007/s11481-021-10007-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Accepted: 07/29/2021] [Indexed: 12/29/2022]
Abstract
Cocaine use is commonly associated with increased chronic systemic inflammation. However, the drivers for cocaine use-mediated systemic inflammation are not fully understood. In the current study, we recruited individuals with cocaine use disorder and healthy individuals who did not use cocaine and collected paired saliva and blood samples. The saliva samples were used to assess the oral microbiome, and the plasma samples were evaluated for 33 cytokines and chemokines. Cocaine users exhibited decreased saliva microbial diversities compared to non-users. Streptococcus was the only increased genus in the saliva from cocaine users, whereas several genera were decreased in cocaine users compared to non-users. Notably, cocaine users exhibited increased plasma levels of several monocyte activation markers, including monocyte chemoattractant protein (MCP)-4, macrophage inflammatory protein (MIP)-3α, macrophage-derived chemokine (MDC), and thymus and activation-regulated chemokine (TARC), all of which were correlated with increased saliva levels of three Streptococcus species. Furthermore, treatment with Streptococcus or its lipoteichoic acid preferentially activated primary human monocytes to produce proinflammatory cytokines and chemokines, such as MIP-3α and TARC, in vitro compared to controls. However, monocytes failed to produce these chemokines after exposure to cocaine or cocaine plus bacteria compared to medium or bacteria alone. This study revealed that chronic cocaine use-associated inflammation in the blood may result from increased oral Streptococcus and its effects on myeloid cell activation, but does not result from cocaine directly.

How Do Drugs Affect the Skeleton? Implications for Forensic Anthropology. BIOLOGY 2022; 11:biology11040524. [PMID: 35453723 PMCID: PMC9030599 DOI: 10.3390/biology11040524] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 02/21/2022] [Accepted: 03/18/2022] [Indexed: 01/10/2023]
Abstract
Simple Summary Forensic anthropologists analyze human remains to assist in the identification of the deceased, predominantly by assessing age-at-death, sex, stature, ancestry and any unique identifying features. Whilst methods have been established to create this biological profile of the skeleton, these may be influenced by a number of factors. This paper, for the first time, provides an overview from a reading of the clinical and pharmacological literature to explore whether the intake of drugs can affect the skeleton and whether these may have implications for forensic anthropology casework. In effect, drugs such as tobacco, heroin, and prescription medications can alter bone mineral density, can increase the risk of fractures, destroy bone and changes to the dentition. By considering how drugs can affect the skeleton, forensic anthropologists can be aware of this when attempting to identify the deceased. Abstract Forensic anthropologists rely on a number of parameters when analyzing human skeletal remains to assist in the identification of the deceased, predominantly age-at-death, sex, stature, ancestry or population affinity, and any unique identifying features. During the examination of human remains, it is important to be aware that the skeletal features considered when applying anthropological methods may be influenced and modified by a number of factors, and particular to this article, prescription drugs (including medical and non-medical use) and other commonly used drugs. In view of this, this paper aims to review the medical, clinical and pharmacological literature to enable an assessment of those drug groups that as side effects have the potential to have an adverse effect on the skeleton, and explore whether or not they can influence the estimation of age-at-death, sex and other indicators of the biological profile. Moreover, it may be that the observation of certain alterations or inconsistencies in the skeleton may relate to the use of drugs or medication, and this in turn may help narrow down the list of missing persons to which a set of human remains could belong. The information gathered from the clinical and medical literature has been extracted with a forensic anthropological perspective and provides an awareness on how several drugs, such as opioids, cocaine, corticosteroids, non-steroidal anti-inflammatory drugs, alcohol, tobacco and others have notable effects on bone. Through different mechanisms, drugs can alter bone mineral density, causing osteopenia, osteoporosis, increase the risk of fractures, osteonecrosis, and oral changes. Not much has been written on the influence of drugs on the skeleton from the forensic anthropological practitioner perspective; and this review, in spite of its limitations and the requirement of further research, aims to investigate the current knowledge of the possible effects of both prescription and recreational drugs on bones, contributing to providing a better awareness in forensic anthropological practice and assisting in the identification process of the deceased.

Abstract
The aim of the present study was to compare the prevalence of dental caries between crack cocaine users and a control group. The study included 106 participants in each group matched for age, sex, and exposure to tobacco. Crack cocaine users were selected from institutions for the treatment of chemical dependency, and the control group was recruited from a public school and among patients who sought dental care. A calibrated examiner determined dental caries experience [Decayed, Missing and Filled Teeth (DMFT) index]. The severity of tooth decay was determined using the Significant Caries Index (SiC). The prevalence of dental caries (DMFT ≥ 1) was 96.2 and 81.1% among the crack cocaine users and nonusers, respectively. Crack users had higher mean DMFT values (7.16 versus 4.92) for the decayed and missing components as well as a higher percentage of individuals with highly severe caries compared to nonusers. After the adjustments in the multivariate model, the prevalence of caries was 18% higher among the crack users (prevalence ratio: 1.18; 95% confidence interval: 1.08-1.30). Age, family income, crack cocaine use, and dental calculus were associated with the occurrence of dental caries. In conclusion, the prevalence of caries was higher among the crack users compared with the control group and remained associated with dental caries in the multivariate analysis.

Abstract
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.

Abstract
Integrative review aiming to detect oral changes in cocaine abusers. The main oral changes, methods of diagnosis and treatment were identified. Good anamnesis and qualified health professionals are necessary.
Introduction Cocaine is one of the most often used psychoactive drugs worldwide, being extracted from the leaves of Erytroxylus coca plant. Its abusive use can trigger several consequences for the human body, including the oral cavity. Objective To identify the oral disorders that are most commonly found in individuals who abuse cocaine, in addition to the main diagnostic and treatment methods. Methods An integrative review was carried out on the databases: LILACS, BBO, LIS, MEDLINE, SciELO, Science Direct and PubMed. The following keywords were used: “Cocaína”, “Boca”, “Palato” and “Odontologia”, together with their synonyms and variations in English, obtained from DeCS and MeSH. The inclusion criteria were original articles, articles in Portuguese, English and Spanish, studies involving individuals, without restriction related to the year of publication. Animal studies, literature reviews, book chapters, theses and dissertations were excluded. Results In total, 1373 records were identified. Of these, 22 articles were selected to comprise the review. Several oral alterations caused by cocaine abuse were found, primarily perforation of the palate, predisposition to periodontal diseases, temporomandibular disorders, bruxism, damage to oral tissues, dental caries, destructive lesions of the facial midline, xerostomia and ageusia. Among the diagnostic methods used by the professionals, anamnesis, intraoral examinations and head and neck computed tomography were the most frequently mentioned. As for treatment, in patients with palatal perforation, the reconstruction of the affected area or the use of prosthetic obturators is carried out. Conclusion The management of these patients is not an easy task, as many of the users do not even seek professional help. The health professionals must be able to recognize these manifestations and alterations to establish timely and accurate diagnosis and treatment planning.

Salivary flow rates and buffer capacity and its relationship with oral health status: a cross-sectional study on crack-cocaine-addicted males. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2020; 27:41876-41884.

Abstract
This cross-sectional study evaluated the saliva profile in crack-cocaine-addicted males and its relationship with dental caries, periodontal disease, and oral mucosal lesion (OML) using 148 adult male volunteers (37 addicted; 111 non-addicted) at the School of Dentistry, Federal University of Bahia. Data on decayed, missing and filled teeth (DMFT), periodontal disease and OML were collected from the clinical examination of the participants. Samples were analysed for the salivary flow rate (SFR) of unstimulated and wax-stimulated whole saliva and the saliva buffer capacity. Bivariate and regression analyses were conducted to assess the salivary profile and its association with the oral status of addicted participants (α = 0.05). The mean buffer capacity of stimulated saliva was significantly lower in the addicted participants (pH 5.2 ± 1.7) than in the non-addicted group (pH 5.8 ± 1.3, p = 0.03). In the addicted group, OML was associated with a stimulated SFR < 1.0 mL/min (OR = 11.98, 95% CI = 1.30-27.10, p = 0.04). The DMFT index and periodontal disease were not associated with the salivary profile, but with older age (OR = 7.20, 95% CI = 1.51-31.14, p = 0.01) and lower education levels (OR = 24.00, 95% CI = 1.68-341.00, p = 0.02), respectively. In conclusion, addiction was associated with the lower buffer capacity of stimulated saliva, and OML was associated with lower-stimulated salivary flow rate. Periodontal disease or DMFT was not associated with salivary factors in addicted males. Therapy approaches dealing with saliva status may be important for use with addicted males to reduce OMLs.

Abstract
OBJECTIVE Salivary proteomic analysis may help to understand physiopathological changes in crack cocaine dependents. This study aimed to compare the salivary protein profile between crack cocaine dependents and non-drug users. DESIGN Nine heavy smokers and alcohol consumers men admitted to rehab due to crack cocaine abuse and nine non-drug users age-matched men were evaluated. Unstimulated whole saliva was collected. Proteomic analysis was performed by mass spectrometer. Data were processed using ProteinLynx GlobalServer software. Results were obtained by searching the Homo sapiens database from the UniProt catalog. The search tool IBI-IMIM was used to identify proteins candidates for biomarkers. RESULTS The mean age of crack cocaine and control groups was 36.89 ± 7.78 and 35.78 ± 6.68 years, respectively. 458 salivary proteins were identified in both groups; 305 proteins in the crack cocaine group. Among the 68 proteins presented in both groups, 29 were down-regulated (i.e. "Statherin" and "Transforming growth factor-beta-induced protein ig-h3" were down-regulated at least 10-fold) and 27 up-regulated (i.e. "Negative elongation factor" was up-regulated 19-fold) in the crack cocaine group compared to controls. 90 out of the 458 proteins found in the proteomic analysis were identified as candidates for biomarkers of diseases. Among these, 65 (72.22 %) were detected in the crack cocaine group. CONCLUSION Crack cocaine dependents with chronic alcohol and tobacco use have a higher number of proteins in saliva compared to non-drug users. 22.3 % of salivary proteins present in crack cocaine dependents were present in controls; 3.9 % of them were expressed in similar quantity.

Abstract
Background In the dental environment there is not much talk about the oral manifestations resulting from the use of drugs, because in general the issue of drugs is a very difficult subject to deal with.
Therefore, the objective of this work is to understand what are the most obvious manifestations in the oral cavity and as the dentist can detect them.
Material and Methods In order to carry out this bibliographical review, a scientific article search was made by consulting the PubMed database. The abstracts were read to recruit only what was consistent with the chosen topic.
Results The 23 sources of information affirmed the relationship between a bad state of general health, and more in the specific, bad state of oral cavity.
Conclusions The most relevant manifestations were: decay, loss of teeth and precancerous lesions. These manifestations were present in most of the cases studied. All this is a consequence of the drug and the lifestyle acquired by the drug users studied. Key words:Drug, caries, meth mouth, periodontitis, xerostomia.

Abstract
The aim of this cross-sectional study was to evaluate the prevalence of oral mucosal lesions (OMLs) and their association with crack/cocaine addiction in men. Clinical oral examination was performed in 161 adult male patients at the School of Dentistry of the Federal University of Bahia, Brazil. Crack/cocaine addiction was determined from the medical records, and all drug-addicted individuals used both crack and cocaine. All participants (40 crack/cocaine-addicted men and 121 non-addicted men) underwent a systematic evaluation of the lips, labial mucosa, commissures, buccal mucosa and sulcus, gingiva and alveolar ridge, tongue, floor of the mouth, and soft and hard palate by a single examiner. Bivariate and regression analyses were conducted to assess for the presence of OMLs and the association of OMLs with crack/cocaine addiction. OMLs were found in 22 participants with a significantly greater prevalence in the crack/cocaine-addicted group (25 vs. 9.9%; p = 0.01). The most prevalent types of lesions in the addicted group were traumatic ulcer and actinic cheilitis (7.5% for each) followed by fistulae associated with a retained dental root (5%). After adjusting for covariates, crack/cocaine addiction was significantly associated with OMLs (OR = 2.87; 95% CI = 1.08-7.67; p = 0.03). The prevalence of OMLs was higher in crack/cocaine-addicted individuals, and crack/cocaine addiction was significantly associated with OMLs. A public health program aimed at the early diagnosis and treatment of OMLs is vital to improving the oral health status of individuals addicted to crack/cocaine.

The Affective and Neural Correlates of Heroin versus Cocaine Use in Addiction Are Influenced by Environmental Setting But in Opposite Directions. J Neurosci 2018; 38:5182-5195. [PMID: 29760180 DOI: 10.1523/jneurosci.0019-18.2018] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2018] [Revised: 04/18/2018] [Accepted: 04/25/2018] [Indexed: 01/13/2023] Open
Abstract
Previous studies have shown that individuals with heroin and cocaine addiction prefer to use these drugs in distinct settings: mostly at home in the case of heroin and mostly outside the home in the case of cocaine. Here we investigated whether the context would modulate the affective and neural responses to these drugs in a similar way. First, we used a novel emotional task to assess the affective state produced by heroin or cocaine in different settings, based on the recollections of male and female drug users. Then we used fMRI to monitor neural activity during drug imagery (re-creating the setting of drug use) in male drug users. Consistent with our working hypothesis, the majority of participants reported a shift in the affective valence of heroin from mostly pleasant at home to mostly unpleasant outside the home (p < 0.0001). The opposite shift was observed for cocaine; that is, most participants who found cocaine pleasant outside the home found it unpleasant when taken at home (p < 0.0014). Furthermore, we found a double dissociation, as a function of drug and setting imagery, in BOLD signal changes in the left PFC and caudate, and bilaterally in the cerebellum (all p values <0.01), suggesting that the fronto-striatal-cerebellar network is implicated in the contextualization of drug-induced affect. In summary, we report that the same setting can influence in opposite directions the affective and neural response to psychostimulants versus opiates in humans, adding to growing evidence of distinct substrates for the rewarding effects of these two drug classes.SIGNIFICANCE STATEMENT The rewarding effects of addictive drugs are often thought to depend on shared substrates. Yet, environmental influences can unmask striking differences between psychostimulants and opiates. Here we used emotional tasks and fMRI to explore the influence of setting on the response to heroin versus cocaine in individuals with addiction. Simply moving from one setting to another significantly decreased heroin pleasure but increased cocaine pleasure, and vice versa. Similar double dissociation was observed in the activity of the fronto-striatal-cerebellar network. These findings suggest that the effects of opiates and psychostimulants depend on dissociable psychological and neural substrates and that therapeutic approaches to addiction should take into account the peculiarities of different drug classes and the settings of drug use.
