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

Impact of licit and illicit substances on the oral health-related quality of life in adolescents

OBJECTIVE

To assess the impact of the consumption of licit and illicit substances on the oral health-related quality of life (OHRQoL) of adolescents from public schools in the south of Brazil.

METHODS

This cross-sectional study was carried out with a random sample of adolescents aged between 17 and 18 years old from Santa Maria, Brazil. The consumption of licit and illicit substances was measured through a self-administered questionnaire with questions from the National Survey of Scholar Health. The OHRQoL was collected using the Brazilian short version of Child Perceptions Questionnaire 11-14 (CPQ11-14). Multilevel Poisson regression models were used to estimate the association between the outcome and the explanatory variables where the adolescents (first level) were nested in their schools (second level).

RESULTS

A total of 768 adolescents were evaluated. Of these, about 15.6% have already used illegal substances. Adolescents who reported the use of illicit substances had 28% higher CPQ11-14 scores when compared to their counterparts. Alcohol use was also related to worse levels of OHRQoL, while the consumption of cigarettes acted as a protective factor.

CONCLUSIONS

This study found an association between the use of alcohol and illicit drugs with worse levels of OHRQoL.

Bisphosphonates and osteonecrosis of the jaws: Clinical and forensic aspects

OBJECTIVE

This manuscript aims to provide a comprehensive review of the current knowledge in the pathophysiology, diagnosis, prevention, and other relevant clinical and forensic aspects of a potentially severe complication known as medication-related osteonecrosis of the jaw (MRONJ) while synthesizing state-of-the-art information on bisphosphonates and introducing a possible differential diagnosis.

DESIGN

An extensive search was conducted in PubMed (U.S. National Library of Medicine) without a time or language constraint, focusing on the epidemiology, pathophysiology, risk factors, site specificity, signs and symptoms, differential diagnosis, prevention, and forensic aspects of MRONJ. All types of original articles, reviews, case reports, short communications, opinion articles, guidelines, and letters to editors were considered to produce a complete review on this subject.

RESULTS

MRONJ prevention relies on a multidisciplinary approach and is critical since truly effective treatments are lacking. This therapeutic challenge is partly due to uncertainty regarding this condition's pathophysiology. Differential diagnosis of osteonecrosis of the jaws associated with krokodil abuse, one of the most dangerous and homemade psychoactive illicit substances, should be considered.

CONCLUSIONS

Further research into the etiology and site specificity of MRONJ is encouraged, aiming to develop novel treatment prospects. Indeed, comprehending this would allow for increased efficacy and therapeutic options while emphasizing the importance of prevention. In addition, we advocate for greater consensus among the various societies regarding MRONJ's treatment and management.
