Distinguishing Subjective Halitosis.

Halitosis is chronic, endogenous malodor that is etiologically classified. Subjective halitosis, which may appear in clinically neurologic (neurogenic) or psychologic (psychogenic) forms, cannot be confirmed by using tests or performing visual inspection despite insistent complaints of malodor by the patient. Neurogenic forms mainly consist of chemosensory dysfunctions (dysguisa, dysosmia) and self-halitosis (retronasal olfaction, bloodborne olfactory receptor responses, phantosmia); whereas psychogenic forms are olfactory hallucinations, halitophobia, olfactory obsession, and delusional halitosis. This article reports clinically important properties of subjective halitosis that may be difficult to manage and provides a tool to aid dental pracitioners. Practitioners can identify suspected subjective halitosis cases by asking patients simple questions to distinguish between subjective and objective forms.

Interdisciplinary approach to treating a patient with amelogenesis imperfecta: a clinical report.

Treatment of a patient with amelogenesis imperfecta (AI) presents a real problem from both functional and esthetic points of view. An esthetic result also will result in an improvement in the patient's quality of life. This clinical report illustrates the oral rehabilitation of a 24-year-old man diagnosed with hypomature type of AI. The aim of treatment was to both restore esthetics and improve masticatory function. Esthetic expectations of the patient were successfully attained by placing all-porcelain crowns from canine to canine in each arch, 12 crowns total. Moreover, metal-ceramic three-unit fixed partial dentures for the missing mandibular right first molars were fabricated for the patient's masticatory function. Resin composite restorations were applied to the maxillary premolars, the maxillary right first molar, the mandibular left premolars, and the right first premolar to modify the occlusion. No deterioration in the restorations and no pathology associated with the rehabilitation were found at the 1-year recall, and the patient's esthetic and functional expectations were satisfied. CLINICAL SIGNIFICANCE This article provides an overview of an interdisciplinary approach to treating the difficult condition of AI using a combination of treatments to achieve optimal esthetics and function.
