Oral Health and Caries Prevention: How Tongue Hygiene Helps Maintain Balance of Microbiota and Overall Health in Pediatric Patients.

Background/objectives: The tongue harbors about two-thirds of the microorganisms present in the mouth; the stable bacterial population consists mainly of aerobic and facultative anaerobic streptococci. These bacterial colonies, found more frequently on the tongue than on the outside of the hard part of the dental enamel in children younger than 18 months, suggest that the tongue is a potential bacterial reservoir. The aim of this review is to examine the scientific literature to clarify whether the mechanical removal of bacterial biofilm on the tongue can have a positive effect on caries prevention, with the reduction in colony-forming unit (CFU) of salivary streptococcus and the whole-mouth plaque index (FMPS).

Potential of photodynamic therapy in the management of infectious oral diseases.

Photodynamic therapy (PDT) can take place in the presence of three elements: Light with an appropriate wavelength; a photosensitizer; and the presence of oxygen. This type of treatment is very effective overall against bacterial, viral and mycotic cells. In the last 10 years many papers have been published on PDT with different types of photosensitizers (, methylene blue, toluidine blue, indocyanine green, curcumin-based photosensitizers), different wavelengths (, 460 nm, 630 nm, 660 nm, 810 nm) and various parameters (, power of the light, time of illumination, number of sessions).

Melkersson-Rosenthal syndrome: A case report.

Key Clinical Message: Melkersson-Rosenthal syndrome (MRS) remains an enigmatic pathology due to an unknown etiology. Our report, of a 69-year-old man with MRS misdiagnosed for about 40 years, underlines the diagnostic difficulty of this condition. A holistic view of the patient, with a correct medical history investigation, are often decisive in the diagnosis of MRS.

Epidemiological evaluation of patient compliance regarding oral health and hygiene during the COVID-19 period.

Unlabelled: This work aimed to report values on oral hygiene habits at home during the pandemic and compare the differences between previous oral hygiene habits. A total of 1,136 questionnaires were filled in via a link sent through email to the patients. The answers show that although they had more time during the pandemic, they spent less time on dental and tongue hygiene.
