Comparative Evaluation of Fluoride Release from Four Commercially Available Pediatric Dental Restorative Materials.

Objectives: The aim of this study was to evaluate the fluoride-releasing abilities of commercially available restorative materials such as-Activa™ BioActive-restorative™ material, Zirconomer (Shofu Inc), Beautifil® II (Shofu Inc), GC Gold Label 9 high strength posterior restorative glass ionomer cement (GIC Corp). Materials and methods: A total of 40 disk specimens (10 of each material) were placed into distilled/deionized (DI) water and the fluoride release was measured for 30 days. Fluoride ion measurement was performed at the end of the 1st, 3rd, 7th, 15th, and 30th day under normal atmospheric conditions by fluoride ion selective electrode (F-ISE) (Orion 9609 BNWP, Ionplus SureFlow fluoride electrode, Thermo Scientific, United States of America) coupled to a benchtop analyzer (Hachsen Ion+). Results: All the materials included in the study exhibited fluoride release. Although there were differences in the amounts of fluoride released between Activa™, Zirconomer, and GC Gold Label 9 the mean difference between these three groups was not found to be statistically significant. Beautifil® II showed low amounts of fluoride released at all time intervals. Conclusion: Among the above-compared materials Activa™ and Zirconomer exhibit both improved mechanical properties as well as they have fluoride-releasing ability so can be preferred over conventional glass ionomer restorations.

Orofacial Myofunctional Therapy in Tongue Thrust Habit: A Narrative Review.

AIM AND OBJECTIVE: The respective review article is to provide an overview of the various exercises in orofacial myofunctional therapy (OMT) as a treatment modality for tongue thrust habit. Tongue thrust is the persistence of an infantile swallow pattern during late childhood. This leads to breathing and speech difficulties, open bite, and protruded teeth. During formative years, most children successfully transition from an infantile to a mature swallowing pattern. However, a few develop a retained infantile swallow and tongue thrust habit which could be due to abnormal habit like thumb sucking or an underlying cause like enlarged adenoids. Adverse effects of these habits can be avoided by early detection and intervention in a growing child. Tongue thrust can be treated in different ways with early diagnosis, removal of underlying causes, correcting tongue posture, and breaking of habit with the use of orthodontic appliances. This review article is focused on the various OMT techniques employed for the correction of tongue thrust. There are several exercises in OMT which can help a child with tongue thrust. These can be performed at home under the supervision of the child's parents. Orofacial myofunctional therapy has provided a dramatic and positive influence on patients treated for tongue thrust. The joy of eating, speaking, and correct breathing can be regained along with confidence, self-esteem, and improved quality of life. Clinically, OMT plays a positive role by not only improving swallow but also the posture of tongue, improper muscle function, and reduces relapse of previous orthodontic treatments.
