Prevalence of Dental Caries in Persons With or Without Long‐Term Experience of Positive Airway Pressure‐Treated Obstructive Sleep Apnoea

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Oral dryness is common in persons with untreated obstructive sleep apnoea (OSA) as well as in those using positive airway pressure (PAP). OSA with or without PAP treatment could therefore be a risk factor of dental caries. Objectives To describe and compare the prevalence of dental caries among persons with or without PAP‐treated OSA.

Transillumination‐Aided Infiltration of MIH‐Affected Molars: Evaluation of the Clinical Workflow

International Journal of Paediatric Dentistry, EarlyView.
ABSTRACT Background Enamel affected by molar incisor hypomineralisation (MIH) exhibits reduced mechanical properties due to its disorganised prismatic structure, lower mineral density and higher protein content. These alterations increase porosity and susceptibility to posteruptive enamel breakdown.
