Therapeutic efficacy of a probiotic preparation on idiopathic halitosis: a retrospective observational study.

Idiopathic halitosis is an unusual condition of unclear causes, which has never been thoroughly investigated. We aimed to explore the role of small intestinal bacterial overgrowth (SIBO) in the pathogenesis of idiopathic halitosis, and to evaluate the therapeutic efficacy of a probiotic preparation on this condition. This retrospective observational study included 162 idiopathic halitosis patients and 198 healthy controls (HCs).

Features of Idiopathic Halitosis and Its Association With Low-Grade Systemic Inflammation.

Objectives: Idiopathic halitosis is occasionally encountered in clinical practice, yet with scarce reports. This work aimed to investigate its features and potential association with low-grade systemic inflammation (LGSI).

Methods: This retrospective study reviewed idiopathic halitosis from 2469 halitosis patients and compared them with 63 healthy controls (HCs).

[Application of the pin-hole marker measurement of the irregular silicone impression accuracy].

Purpose: To investigate the feasibility of the pin-hole marker measurement of the irregular silicone dental impression accuracy.

Methods: The metal model simulating abutment preparations had triangle-formed circular needles on the surface. Two silicone impressions were made by the metal model with the corresponding pin-hole markers.
