    The effect of a single application of different fluoride varnishes on enamel subsurface lesions in vitro

    This in vitro study aimed to evaluate the therapeutic effect of different fluoride ion (F) varnish formulations for controlling the carious development of enamel subsurface lesions and the F release into artificial saliva for 2 hr, 24 hr, 48 hr, and 7 days. Artificial enamel carious lesions were created and divided into 6 groups (5 varnish groups and a control group). Varnishes were applied to enamel specimens and then the specimens were incubated in artificial saliva, with the artificial saliva replenished daily. Varnish was removed and lesions were remineralized in artificial saliva for 24 hr. Surface microhardness was measured three times: (i) initially, (ii) after creating the artificial enamel lesions, and (iii) after applying the varnishes. The F release was analyzed after 2 hr, 24 hr, 48 hr, and 7 days of exposure using an ion-selective electrode. Data were analyzed using a One-way Analysis of Variance with the Tukey-Kramer Multiple Comparisons test and the Kruskal-Wallis test with the Dunns Multiple Comparisons test. The highest percentage surface microhardness recovery was found for the treatment with the MI Varnish. According to the percentage surface microhardness recovery results, a statistically significant difference was found between the varnishes and the control group (p < 0.05 and < 0.001). All varnishes released measurable levels of fluoride ions. However, the release of F was the highest in the MI Varnish group (p < 0.01). Duraphat, Enamel Pro Varnish, and MI Varnish released the most F into artificial saliva. Calcium phosphate-based F varnishes improve the capacity of the enamel surface re -hardening. CPP containing F varnish had the highest release of F as compared to the other F releasing varnishes. Further in vivo investigations are also required to prove the clinical applications of the different ingredients containing varnishes.

    Retrospective evaluation of traction time for impacted dilacerated maxillary central incisors in mixed dentition
    (2023-04-01) ŞEN YAVUZ, BETÜL; YILMAZ, MÜESSER AHU; HAZNEDAROĞLU, EDA; UĞURLU, FAYSAL; MENTEŞ, ALİ RECAİ; Şen Yavuz B., Yılmaz M. A., Haznedaroğlu E., Sezer B., Okutan A. E., Sezgin B. I., Özçelik M., Sezgin G. İ., Uğurlu F., Menteş A. R.
    PurposesThis study aimed to contribute to understanding the factors affecting the time of traction treatment of impacted dilacerated maxillary central incisors.MethodsThis retrospective study included children aged 8 – 11 years with a history of trauma, who applied to the pediatric dentistry clinics of Marmara University, School of Dentistry, between December 2013 and December 2019, and were treated for unilateral impacted dilacerated maxillary upper central incisors. Children\"s age, sex, digital panoramic radiographs, cone-beam computed tomography, and intraoral photographs were retrieved from electronic dental health records. The effects of children\"s age, sex, the direction of impacted teeth, distance of the teeth to the top of the alveolar crest, and root dilaceration level on traction time were analyzed by Mann-Whitney U test and Spearman\"s rank correlation coefficient test.ResultsThe inverse position of the incisors significantly increased the traction time (P = 0.012). However, the traction time did not differ according to the sex of the children (P = 0.707) or the level of root dilaceration (P = 0.429). No correlation was observed between the traction time and the age of children (P = 0.644) or the distance of the incisors from the top of the alveolar crest (P = 0.397).ConclusionsIn cases of the forced eruption of for the impacted dilacerated maxillary central incisors, the direction of the teeth should be evaluated when deciding on the treatment plan, as it may affect the treatment time.
