“…Since permanent teeth were harder than primary teeth, it was expected that they would be more resistant to dental erosion however, we noticed that primary teeth had a greater percent decrease of microhardness but without significance after 28 days of incubation in the different medications. That was in agreement with other studies that observed no statistically significant differences between the rate of erosion progress in primary and permanent teeth (15,25) . Whereas other studies observed that dental erosion proceeds more rapidly in primary than in permanent enamel (16,24) .…”

Purpose: To evaluate the erosive effect of pediatric liquid medicinal syrups on primary and permanent enamel. Materials and methods: Eighty primary and permanent teeth were equally divided into eight subgroups (n=10), according to the immersion solutions: Depakine, Ventolin, Sansovit, and Artificial saliva. The immersion cycles of the drugs were conducted under a 1-min agitation three times daily for 28 days. Enamel microhardness measurements were taken place at 0,7,14,21, and 28 days. The pH, titratable acidity, buffering capacity, and viscosity of the solutions were evaluated. A Scanning electron microscopy and statistical analysis of enamel microhardness measurements were assessed. Results: All the tested groups of the drugs had proven to produce significant demineralization of enamel after 28 days of exposure. At baseline, the permanent enamel showed higher mean enamel microhardness values than primary teeth. Generally with all the tested drugs, the primary teeth showed more decrease in enamel microhardness than permanent but without significance. The primary group (0-28days), the highest decrease of enamel microhardness was recorded in Sansovit group, then Ventolin, followed by Depakine group without significant change between the tested drugs, while in the permanent group, the highest decrease of enamel microhardness was recorded in Sansovit, then Depakine, followed by Ventolin group without significant change between the tested drugs. Kruskall Wallis test revealed a significant difference between tested drugs and control groups in both substrates. Conclusion: This study revealed that medicines used in the study could erode teeth even though the pH was above critical pH if it had high sugar content and viscosity. Sugar-free formulations have the ability to produce an erosive effect if they have low pH, high titratable acidity, high buffering capacity, and viscosity. This study showed that permanent teeth had higher mean enamel microhardness values than primary teeth, however no significant difference in the erosive potential of both types of teeth.

“…Deciduous tooth enamel has lower inorganic content than permanent tooth; thus, it has a lower microhardness. The mean baseline micro-hardness values of deciduous enamel samples ranged from 340.45 ± 15.62 to 345.84 ± 6.97 VHN in our study, which was in accordance with that of Molla Asadollah et al [ 24 ] Surface hardness increased after pH-cycling in all groups indicating mineral gain happened. BAG exhibited superior recovery capacity in accordance with other studies [ 25 ] since the lowest concentration of it successfully restored the surface hardness, and showed significantly higher % REMH than the DDW.…”

Background Early childhood caries has been designated as a serious public health problem. The traditional restoration method is very challenging, especially in uncooperative patients. Non-invasive therapy, like remineralization agents, which have been developed to reverse the demineralization progress at the early stage of caries, may be a better choice. This study aimed to evaluate the remineralization efficacy of different concentrations of 45S5 bioactive glass (BAG) on artifical carious lesions of deciduous enamel. Methods 65 caries-like enamel lesions of the deciduous teeth were assigned to 5 groups (n = 13) and transported to a 14 days pH-cycling: Group A: 2%BAG, Group B: 4%BAG, Group C: 6%BAG, Group D: 8%BAG, and Group E: deionized water (DDW, negative control). 8 sound (Group F) and 8 demineralized teeth (Group G) were prepared for contrast. The recovery power of mechanical property was evaluated by Vickers hardness test through the recovery of enamel microhardness (%REMH). Surface morphology, mass fraction of Ca and P ions, and Ca/P atomic ratio were analyzed by scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (EDX). Moreover, Fourier transform infrared spectroscopy equipped with attenuated total reflectance was used to identify the chemical structure of newly formed compounds. Results % REMH were (42.65 ± 1.35), (52.59 ± 2.96), (57.40 ± 1.72), (52.91 ± 2.55), (12.46 ± 2.81) in 2%BAG, 4%BAG, 6%BAG, 8%BAG, and DDW groups respectively. Micro-spherical particles were deposited in all BAG groups and 6% BAG showed the densest and most uniform surface. EDX analysis identified significantly higher Ca(wt%) and P(wt%) in four BAG groups than in the demineralized group (p < 0.005), while 6% BAG showed the highest mineral gain efficacy. The infrared spectrum demonstrated that newly mineralized crystals were consisted of type-B hydroxycarbonate apatite. Conclusion BAG possessed a promising remineralization effect on artificial lesions in deciduous enamel by recovering enamel surface mechanical property, morphology and chemical elements. Among them, 6% BAG performed the greatest overall efficacy. Acting as a new caries-arresting biomaterial, 45S5 BAG has the potential to facilitate the adaptation of better carious prevention strategies in children.

“…Applications of lasers in medicine have been encouraged in various fields such as dermatology, ophthalmology, dentistry, and several surgical procedures. [1][2][3] Several studies have been conducted in the field of skin treatment using the new applications of laser and selective photothermolysis over the past two decades. 4,5 The selection of laser is dependable on the heat attained in the thermophore, the depth of wavelengths that permit deeper penetration into the skin with less scattering, [6][7][8] the absorption peaks, and the localization of heat in the target that should be shorter in time than the thermal relaxation time.…”

There are several types of medical settings which use lasers. Dermatologists use lasers as it is non-invasive with preferential cosmetic outcomes and finer wound healing. The types of lasers are relying on their wavelengths and delivery systems.Over time, by using several distinct devices and strategies, new lasers have been generated; as a consequence, they are manipulated in a wide range of dermatological settings. In this review, laser applications in various vascular, infectious, and hyperpigmented cutaneous lesions were framed. We aimed to represent the fitness of phototherapy for each condition as well as the overall challenges that face laser. In addition, low-level laser therapy, and laser resurfacing were noted as the marketable line of lasers in the current time for cosmetic purposes.
