In the UK almost one million individuals use cocaine on a regular basis, implying that dentists are likely to encounter individuals that use cocaine. Regular use of this drug may have several orofacial effects, such as perforation of the nasal septum and palate, gingival lesions and erosion of tooth surfaces. In addition, recent use of cocaine increases the risk of a medical emergency during dental treatment, especially when epinephrine-containing local anaesthetics or retraction cords are used. Therefore, dental treatment should be postponed for 6 to 24 hours after the use of cocaine. [ABSTRACT FROM AUTHOR]

Objective To assess the severity of xerostomia (subjective dry mouth) in haematopoietic stem cell transplantation (HSCT) patients and to investigate the association of xerostomia with other chronic oral complications.Design Cross-sectional study.Study participants and methods Participants were 48 patients with a history of HSCT recruited among members of the Dutch Stem Cell Transplantation Contact Group, and a comparison group of 41 age- and sex-matched individuals. Data were collected using the Xerostomia Inventory (XI score) and a seven-item oral health questionnaire.Results HSCT patients had a higher XI score than the comparison group, and a greater severity of several oral complaints: painful oral mucosa, altered taste, limited opening of the mouth and problems with tooth brushing. HSCT patients did not report greater pain during cold stimulation of teeth, chipped and cracked teeth or bleeding gums. In HSCT patients, the XI score correlated significantly with the severity of oral mucosal pain, altered taste, limited opening of the mouth, painful teeth following cold stimuli, chipped or cracked teeth, problems with tooth brushing and bleeding gums. In the comparison group, no correlations were observed between XI score and these oral problems.Conclusion HSCT patients have more severe xerostomia, which is associated with other oral complaints. Dental professionals should monitor these patients post-transplant for oral complications. Symptoms of dry mouth should be relieved and secondary complications should be prevented.
