Osteonecrosis of the maxilla related to long-standing methamphetamine abuse: a possible new aspect in the etiology of osteonecrosis of the jaw

Case Report: Unusual oral cavity changes associated with methamphetamine abuse

Methamphetamine abuse is a growing global health concern, recognized for its highly addictive properties and severe effects on the human body. Commonly referred to as crystal, chalk, or ice, methamphetamine is a synthetic stimulant that can be administered in various ways. Methamphetamine abuse is associated with a spectrum of oral health issues known as "meth mouth," including rampant teeth caries, extensive occlusal tooth wear, periodontal diseases, xerostomia, bruxism, and poor oral hygiene. Despite the significant oral health impact, the exact pathogenesis remains unclear due to the limited number of reported cases and comprehensive studies performed. This case series details changes in oral and general health of different severity associated with methamphetamine abuse, highlighting unusual presentations such as the generalized decrease in teeth sensitivity, which can be associated with aseptic tooth pulp necrosis, hairy black tongue, rampant arrested caries, decreased periodontal inflammation, specific sunflower seed abrasions on antagonistic central incisors, pityriasis rosea skin lesion and palmar erythema. The clinical management was presented in detail and justified, which entails conservative dental, periodontal and oral mucosae treatments and highlighted the need for a comprehensive complex examination of these patients and financial consideration in treatment planning. This case series underscores the need to recognize the diverse oral and general health effects of methamphetamine abuse, which vary with duration and individual symptoms. Patients often withhold substance use, leading to delayed diagnosis until severe manifestations arise. Enhanced awareness among healthcare providers can improve diagnosis and management, offering valuable insights into underlying mechanisms and enabling better care for this high-risk population.

Crystal methamphetamine and its effects on mental and oral health: A narrative review

The purpose of this comprehensive literature review is to present the available evidence on the effects of methamphetamine on mental and oral health, as well as provide an overview of the most widely used medical and dental care strategies in the management of meth mouth. For this purpose, PubMed and Google Scholar electronic databases were searched for relevant articles, yielding 115 search results, which were further scrutinized for their relevance, leaving 55 for a detailed review. The analysis of the gathered data indicates that a comprehensive patient-centered approach that takes into consideration the physical, mental, and social aspects is crucial for mitigating the detrimental effects of increasing methamphetamine use.

Surgical Treatment in Patients with Toxic Phosphorus Osteonecrosis of Facial Skull Middle Zone

During the last few years, in the territory of the Russian Federation, the number of cases of toxic phosphoric osteonecrosis of the jaws has increased against the background of taking drugs of "artisanal" production (pervitin, desomorphin). The aim of our study was to increase the effectiveness of surgical treatment of patients with a diagnosis of toxic phosphorus necrosis of the maxilla. We performed a comprehensive treatment of patients with a history of drug addiction and the above diagnosis. Surgical intervention in the volume of complete resection of pathologically altered tissues and reconstructive techniques using local tissues and a replaced flap made it possible to achieve good aesthetic and functional results in the early and late postoperative period. Thus, our proposed method of surgical treatment can be used in similar clinical situations.

How Do Drugs Affect the Skeleton? Implications for Forensic Anthropology

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.

Is mandibular osteomyelitis a sequela of SSRI-induced dental implant failure? A systematic review & case report

BACKGROUND

To determine if the utilization of selective serotonin reuptake inhibitors (SSRIs) increases the risk of osteomyelitis as a sequela of dental implant failure. We also report the case of a patient on long-term SSRIs who presented with dental implant failure and subsequently developed mandibular osteomyelitis.

METHODS

We performed a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) in PubMed, Google Scholar and Embase, for all records pertaining to SSRIs, dental implants, and mandibular osteomyelitis.

RESULTS

SSRIs are associated with increased risk of dental implant failure, and our results suggest that they may be independently associated with mandibular osteomyelitis in the setting of implant failure. Though there was no evidence of mandibular osteomyelitis specifically following SSRI-related dental implant failure, there were a few case reports on osteomyelitis resulting from failed dental implant osseointegration.

CONCLUSIONS

In the context of long-term SSRI utilization, our findings suggest that osteomyelitis should be considered in the differential diagnosis of patients with recent dental implant placement or failure.

[Morphological features of jaw osteonecroses in injectable drug abuse]

OBJECTIVE

To determine the characteristic features in the structure of jaw bone sections in patients with jaw osteonecrosis caused by the use of homemade methamphetamine (HM) synthesized by the Nagai method.

MATERIAL AND METHODS

The investigation material was jaw sequesters and resected sections in 60 patients, which had been taken during sanitizing surgery for chronic odontogenic osteomyelitis (Group 1, n=30, a comparison group) and jaw osteonecrosis (Group 2, n=30). All the patients in Group 2 confirmed that they had been using HM for at least 2 years. The investigation material was selected only from the patients who had not been found to have congenital or acquired immunodeficiencies or multiple organ failure phenomena. The material was fixed according to the standard procedure; the sections obtained were stained with hematoxylin and eosin and Masson-Goldner. Morphometry used the indicators proposed by the American Society of Bone and Mineral Research Histomorphometry Nomenclature Committee, as well as 6 author parameters. The findings of the investigation were statistically processed using the Statistica 10.0 program (StatSoft, USA) by the nonparametric Mann-Whitney test.

RESULTS

The histoarchitectonics of the mandible bone matrix represented a destructured devitalized tissue complex on the mandibular microspecimens taken from a group of patients with chronic odontogenic osteomyelitis of the jaws. The state of the bone matrix was characterized by the atypical rearrangement with the phenomena of sclerosis, the signs of primary aseptic inflammation with toxic vasculopathy and fibrinoid necrosis, as well as those of secondary pyonecrotic inflammation on the mandibular microspecimens taken in the HM group.

CONCLUSION

The characteristic morphological pattern of jaw osteonecrotic injuries in persons with HM-induced drug abuse is the simultaneous identification of two types of lesions: a primary lesion as aseptic ossifying osteitis and a secondary lesion as pyonecrotic inflammation. The phenomena of toxic vasculopathy and fibrinoid osteonecrosis can serve as one of the criteria confirming the active regular intake of HM.

A case series of uncommon causes of maxillary osteomyelitis: Understanding the pathology and recognizing the risks

Maxillary osteomyelitis is a rare event. With emergence of bisphosphonates, the incidence of jaw osteomyelitis has increased. We report five uncommon cases, with a comprehensive review of etiology and pathology. The correlation between osteonecrosis and osteomyelitis is discussed.

Effect of morphological findings in computed tomography on the quantitative values in single-photon emission computed tomography for patients with antiresorptive agent-related osteonecrosis of the jaw: a cross-sectional study

OBJECTIVE

Quantitative analyses of gamma-ray accumulation in single-photon emission computed tomography (SPECT), and the evaluation of antiresorptive agent-related osteonecrosis of the jaw (ARONJ) have been reported recently. However, the relationship between the quantitative parameters calculated from SPECT and the detailed morphological changes observed in computed tomography (CT) remains unclear. This study aimed to investigate patients' characteristics and morphological changes observed on CT, and their effects on the quantitative values in SPECT.

METHODS

From April 2017 to March 2019, patients diagnosed with ARONJ at our hospital were enrolled. The data obtained before September 2017 were reviewed retrospectively, and other data were collected prospectively. CT scans were evaluated for internal texture, sequestrum formation, periosteal reaction, cortical perforation, bone expansion, and pathological fracture. For quantitative assessment, the ratio of the maximum standardized uptake value (SUV) to the mean SUV in the temporal bone (rSUVmax) was calculated from SPECT images. The factors affecting rSUVmax were investigated by multiple regression analysis. The statistical significance level was set at α = 0.05.

RESULTS

Overall, 55 lesions of 42 patients (median age and interquartile range, 75 [67-80 years], 27 female) were evaluated. Male sex (p = 0.007) and bilateral location (p < 0.0001) were selected as variables in the multivariate analysis. Adjusted coefficient of determination R2 was 0.59 (p < 0.0001).

CONCLUSION

Sex and horizontal progression of the disease may affect individually calibrated SUVs in SPECT for patients with ARONJ.

The role of illicit drugs in developing medication-related osteonecrosis (MRONJ): a systematic review

Medication-related osteonecrosis of the jaw (MRONJ) is a challenging condition to treat. It has primarily been associated with anti-resorptive and anti-angiogenic drugs, which are increasingly being used to prevent adverse skeletally-related complications in patients with cancer and bone pathologies. Although these medications have been proven to cause osteonecrosis of the jaws (ONJ) there are also a number of other drugs that could potentially cause this condition. The aim of this systematic review is to ascertain whether there is an associated risk of osteonecrosis of the jaw (ONJ) in recreational drug users (RDU). Three authors independently searched PubMed, MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials for published reports of osteonecrosis of the jaw (ONJ) in recreational drug users (RDU) or illicit drug users (IDU) who had no history of treatment with anti-angiogenic or anti-resorptive agents. Only 30 studies were eligible for analysis, and all were independently assessed for risk of bias. There was a total of 101 patients with ONJ attributed solely to illicit drug consumption. The most common site of ONJ was the maxilla (n=54). The most common illicit drug related to ONJ was desmorphine, known as 'Krokodil', this was followed by cocaine, methamphetamine, anabolic steroids, and hydrocodone/acetaminophen. In 52 of the cases, the ONJ resolved following treatment, however, eight showed a recurrence. Although all the studies were judged to be at a high risk of bias, the limited data suggest that some patients are at risk of developing ONJ as a result of illicit drug usage. Studies of higher quality are needed to establish the relative risk of ONJ in this patient group.

Dental management of patients with substance use disorder

Substance use disorder (SUD) is a relapsing brain disorder characterized by compulsion and chronicity. SUD has detrimental effects on oral health. Drugs and alcohol negatively impact oral health by inducing a myriad of orofacial conditions including xerostomia, dental caries, periodontal disease, bruxism, pre-cancer and cancer, to name a few. Limited recommendations are available for dental professionals on how best to manage patients afflicted with SUD. The aim of this article is to review the oral health consequences of alcohol and commonly abused drugs to provide guidelines for the public health community and dental professionals. The United Nations estimates that a quarter billion people, representing five per cent of the global adult population, used drugs at least once in 2015. Developing public health interventions that include the participation of dental professionals and access to dental services for persons afflicted with SUD could play a critical role in improving their quality of life, their recovery, and their reintroduction into society.

Novel insight into the management of bisphosphonate-related osteonecrosis of the jaw (BRONJ)

Bisphosphonate-related osteonecrosis of the jaw (BRONJ), characterized by refractory bone exposure, has recently emerged as a serious side effect of bisphosphonate (BPs) treatment. We discuss novel insights that may help to improve the efficacy of BRONJ treatment and prevention. Our report highlights the following: (1) The presence of exposed bone in patients taking BPs does not necessarily reflect BRONJ, and diagnoses of oral ulceration with bone sequestration and malignancy must be excluded. (2) Osteonecrosis type of BRONJ is difficult to avoid using preventive dental measures alone. However, as with osteomyelitis type of BRONJ, preventive dental measures are indispensable for reducing the risk of secondary infection and disease progression. (3) The importance of tooth extraction as a risk factor for BRONJ among patients taking BPs has been overstated, particularly when they are administered at low doses. Delaying tooth extraction may increase the risk for the onset and progression of osteomyelitic BRONJ. (4) In patients taking low doses of BPs, dental implant surgery is not necessarily contraindicated if there are no other risk factors, such as combined use of corticosteroids or concomitant diabetes. However, the risk of BRONJ due to peri-implantitis must be explained when obtaining patient consent.

[Current situation and future issues of antiresorptive agent-related osteonecrosis of the jaw]

Bisphosphonate-related osteonecrosis of the jaw (BRONJ), which is characterized by refractory bone exposure, has recently emerged as a serious side effect of bisphosphonate (BP) treatment. BRONJ was first thought to be due to administration of high doses of intravenous BP to treat metastatic bone lesions or multiple myeloma. However, more recent studies have indicated that BRONJ also frequently occurs in patients receiving low doses of BP for the treatment of osteoporosis. In addition, patients treated with denosumab, a human monoclonal antibody against receptor activator of nuclear factor-kappa B ligand (RANKL) whose antiresorptive effects differ from those of BP, may develop osteonecrosis of the jaw. Since both BP and denosumab are associated with osteonecrosis of the jaw (ONJ), antiresorptive agent-related ONJ (ARONJ) has been suggested as a comprehensive term. Although the pathophysiology of BRONJ remains unclear and the number of affected patients is increasing in Japan, significant improvements have been made with respect to risk reduction strategies and treatment. Despite the publication of the first position paper on BRONJ in Japan in 2010, an increase of the number of patients of BRONJ is hypothesized to result from an increase in the long-term use of BP. Previous findings have suggested that inadequate preventive measures including restriction of tooth extraction may be responsible for increases in BRONJ incidence.

Meth Mouth-A Growing Epidemic in Dentistry?

In the past two decades, the synthetic style and fashion drug “crystal meth” (“crystal”, “meth”), chemically representing the crystalline form of the methamphetamine hydrochloride, has become more and more popular in the United States, in Eastern Europe, and just recently in Central and Western Europe. “Meth” is cheap, easy to synthesize and to market, and has an extremely high potential for abuse and dependence. As a strong sympathomimetic, “meth” has the potency to switch off hunger, fatigue and, pain while simultaneously increasing physical and mental performance. The most relevant side effects are heart and circulatory complaints, severe psychotic attacks, personality changes, and progressive neurodegeneration. Another effect is “meth mouth”, defined as serious tooth and oral health damage after long-standing “meth” abuse; this condition may become increasingly relevant in dentistry and oral- and maxillofacial surgery. There might be an association between general methamphetamine abuse and the development of osteonecrosis, similar to the medication-related osteonecrosis of the jaws (MRONJ). Several case reports concerning “meth” patients after tooth extractions or oral surgery have presented clinical pictures similar to MRONJ. This overview summarizes the most relevant aspect concerning “crystal meth” abuse and “meth mouth”.

Chemical and Radiation-Associated Jaw Lesions

Osteonecrosis of the jaw is a major public health concern throughout the world. Use of radiotherapy for head and neck cancer and bone antiresorptives and antiangiogenic agents have increased its incidence. Medication-related osteonecrosis of the jaw is more common relative to other types of osteonecrosis. Osteoradionecrosis occurs despite better treatment planning and shielding to minimize collateral damage to bone. Other related necrotic lesions are secondary to usage of recreational drugs and steroids. This article provides comprehensive information about these different types of bone necrosis; provides the readers with radiographic diagnostic criteria and updates on current theories on pathophysiology of osteonecrosis.
