Halitosis and oral health-related quality of life: a case report

Objectives: This is a clinical case of a 36-year-old Dutch male, patient in the Dr. S. van Mesdag Forensic Psychiatric Centre in Groningen. It demonstrates a short-time effect of a tailored oral hygiene self-care intervention in three sessions over a period of 3 months on halitosis and a patient's oral health-related quality of life (OH-QoL). Methods: In addition to a dental screening and professional oral hygiene care, a semi-structured interview was conducted by the dental hygienist, and questionnaires were administered. The questionnaires included were; the Dutch version of the Oral Health Impact Profile-14 (OHIP-14-NL; used as a measurement of OH-QoL), scales for expected social outcomes for having healthy teeth, attitudes towards oral hygiene behaviour (OHB) and dental anxiety. Results: Clinical observations showed an improvement in patient's OHB, while the extreme foetor-ex-ore was reduced to an acceptable level. A retrospective assessment showed that patient's attitude towards the recommended OHB together with his self-perceived OH-QoL had positively increased. Conclusions: This case highlights the value of professional individual oral hygiene instructions performed by a dental hygienist. It also illustrates that a patient's effective OHB may play an important role in the reduction in halitosis and self-perceived OH-QoL. Finally, the retrospective version of the OHIP-14-NL may be an adequate method to assess self-perceived OH-QoL within a relative short period of time.
