Difficulty in Closing Mouth in Patient with Disc Displacement: A Case Report

Abstract

Clinicians are familiar with limitation of opening mouth caused by temporomandibular disorders. Sometimes, patients also complain of difficulty in closing mouth. Difficulty in closing mouth can be caused by anterior, posterior disc displacement, and subluxation of temporomandibular joint (TMJ). In this report, we presented a patient who had a difficulty in both opening and closing mouth. The patient complained of TMJ noises and intermittent limitation of opening mouth, and inability to get teeth back into maximal intercuspal position. Magnetic resonance images revealed that the left TMJ had an anterior disc displacement with relative posterior disc displacement. We reviewed the possible causes, signs and symptoms, and treatment for difficulty in closing mouth with related literatures.

Fabrication and Characterization of Cu Doped CeO₂ by Hydrothermal Process for Antimicrobial Activity

“…Generally, antibacterial agents are classified into natural antibacterial agents, artificial antibacterial agents, and metal antibacterial agents. [1] Among them, silver (Ag) is harmless to the human body, and resistance is not generated, so many applications are possible from clothes to household appliances. [2,3] However, when silver (Ag) is used as an antimicrobial agent, the cost increases from the economic point of view, Research is actively underway to replace silver (Ag) with metal such as copper (Cu), Zn and Al, also with metal oxides such as CeO2 and TiO2, which have a sterilizing effect through the formation of hole pairs during ultraviolet irradiation, as antimicrobial agents.…”
