Evaluating Three Different Gels in Treating and Protecting the Primary Teeth Enamel Surface Erosion
2022 Journal of Research in Medical and Dental Science
ABSTRACT Aim: To compare the effect of NHA gel, HA gel and NaF gel in treating the eroded enamel surface of the primary teeth. Objectives: Detecting the structure changes of primary enamel surface (surface roughness analysis and surface nanostructure) following erosive exposure to Pepsi, after treatment with NHA gel, HA gel and NaF gel and for the treated. Material and methods: NHA, HA gels will be prepared and FTIR test to evaluate it. Thirty sound buccal segment of primary ϔ‹rst or second molar will be exposed to Pepsi for 60 minutes with shaking 3 times daily for 10 days. Then, the erosive effect of the acid beverage on the primary tooth surface enamel will be studied. After that, different treating gels will be applied to study the remineralization effects on the primary surface enamel. In order to evaluate the preventive effect of the NHA-gel, HA-gel and NaF gel on the treated teeth, a second acid beverage exposure will be conducted. At the end, the primary surface enamel of the sample will be studied again to evaluate the protective effect of applied gel. Spectroscopic morphology (2D, 3D picture) will be studied in the three phases. Results: Ra, Rq, Rz decrease in remineralization phase and at least in (NHA, NAF, HA) respectively, with p<0.05 between (NHH, HA) but p>0.05 between (NHA, NAF) also (HA, NAF). Ra, Rq, Rz slightly increase in preventive phase p<0.05 between (NHA, NA) also (NHA, NAF) but p>0.05 between (HA, NAF). Conclusion: 10% NHA gel better than HA, NAF gels in treatment and prevention the effect of erosion cause by Pepsi cola.
Evaluating the effective of three different gels on the color change of primary teeth enamel surface erosion
2025 International Journal of Applied Dental Sciences
Abstract Introduction: The main cause of erosive primary tooth is the routinely consumption of carbonated drinking which induced color change of the enamel especially in child. For that reason, variant of antidemineralization agents has been utilized such as nanohydroxyaptite, hydroxyapatite and sodium fluoride gels both of which (nanohydroxyaptite, hydroxyapatite) have been added to the oral care gels to evaluate the effect of gels on shade. The aim of this study was compared of color change on the treating and prevention the eroded enamel surface of the primary teeth from thee different gels by analysis the vita easy shade. Materials and Methods: Nanohydroxyaptite, hydroxyapatite gels was prepared and Fourier Transform Infrared Spectroscopy test to evaluate them. Thirty sound buccal segment of primary first or second molar was prepared and color was measured then they were exposed to coca cola for 60 minutes with shaking 3 times daily for 10 days. The erosive and color effect of the carbonated drinking on the primary tooth surface enamel was studied by Vita easy shade advance 4 device respectively. They were distributed into three groups according to the different treating gels applied to study the color effects on the primary tooth enamel. In order to evaluate color of the primary tooth enamel of the sample in two different condition. Spectroscopic morphology (two dimension, three dimension picture) was studied in the three phases. Results: In the first phase, shade change was higher in hydroxyapatite followed by nanohydroxyapatite while least in sodium fluoride but with no significant difference. Following multiple pairwise comparisons, all results found to be significant when compare each agent with each other, except when compare nanohydroxyapatite with hydroxyapatite in shade change from 1st to 2nd exposure and in shade from remineralization to 2nd exposure when compare each agent with sodium fluoride, all these results are not significant. Conclusion: Nanohydroxyaptite gel better than hydroxyapatite gel in whiting effect but sodium fluoride gel more effective than others in the treatment phase, nanohydroxyapatite gel better than sodium flouride and hydroxyapatite gels in preventive color change.
Estimation of Serum Level of Neurokinin A in Patients with Periodontitis in Association with Chronic Migraine Disease (Observational Case Control Study)
2025 CENTRAL ASIAN JOURNAL OF MEDICAL AND NATURAL SCIENCES
Abstract: Recently, a relationship was found between periodontitis and chronic migraine. However, there is no evidence of the association between periodontitis and Neurokinin A (NKA) level in chronic migraine patients. As a result, we aimed to measure and compare serum levels of NKA in study and control groups in order to determine whether periodontitis is associated with chronic migraine disease activation. Eightytwo (82) males and females above the age of 18 were recruited. Subjects were divided into four groups: 27 patients with chronic migraine and periodontitis, 27 patients with chronic migraine and clinically healthy periodontium, 20 patients systemically healthy with periodontitis and eight subjects with clinically healthy periodontium and without any systemic disease. Assessment of periodontal status was carried out for all participants. Socio demographic data and comorbidities were assessed by means of a standard questionnaire then blood samples were collected and serum concentrations were separated for NKA. The serum level of NKA were higher in the control group (38±40) and there was a significant difference between the other groups when compared to the control group (P=0.003) and there was a weak negative significant correlation between neurokinin A and clinical periodontal parameters (BOP, Cal, and PPD) between all study groups. According to the findings of this study, the control group had a higher level of serum NKA. As a result, this peptide could be considered an indicator of disease severity and activity for both periodontitis and chronic migraine diseases. So far, no research has backed up our findings. Longitudinal studies are required to validate our findings.
