    Comparison of Er:YAG Modalities (PIPS-SWEEPS) onEliminating of Enterococcus Faecalis Populations
    (2021) Hatipoğlu, Fatma Pertek; Arıcıoğlu, Banu; Hatipoğlu, Ömer; Bahçeci, İlkay
    Background: To determine the effectiveness of novel two Er:YAGlasers modalities, photon-initiated photoacoustic streaming(PIPS\\SSP) and shock wave-enhanced emission photoacousticstreaming (SWEEPS\\AutoSWEEPS) in terms of removalEnterococcus faecalis (E. faecalis) with or without antimicrobialagents [Sodium hypochlorite (NaOCl) and chlorhexidine gluconate(CHX)]. Methods: Forty-two extracted single-rooted mandibular premolarswere prepared, sterilized, and then inoculated with E. faecalis for 4weeks, and randomly divided into to two main and three subgroups(n= 7). Group Ia ( PIPS + distilled water), Group Ib (PIPS + 5%NaOCl), Group Ic (PIPS + CHX), and Group IIa (SWEEPS + distilledwater), Group IIb (SWEEPS + 5% NaOCl), and Group IIc (SWEEPS+ CHX). Following incubation for 48 hours at 37°C, the colonyforming units (CFU) were counted. Results: NaOCl and CHX activated with PIPS\\SSP orSWEEPS\\AutoSWEEPS modalities showed significantly higherreduction rates than distilled water activated with both laser activated methods (p<0.05), but no significant differences weredetected between the NaOCl and CHX groups. Besides, in allgroups, no significant difference was detected between PIPS\\SSPand SWEEPS\\AutoSWEEPS performances in the reduction of CFUcounts (p>0.05). Conclusion: Even novel laser activation methods or modalities arenot sufficient alone to adequately reduce bacterial load and usingantimicrobial agents with laser activation is necessary for the bestreduction for microbial elimination. Novel SWEEPS\\AutoSWEEPSmodalıty with the conical 600?m tip showed no increased efficacycompared with PIPS\\SSP mode. Besides, smaller fiber tip mayincrease the success of applications for minimally invasive accesscavities and preparation.

    RADIOLOGICAL ASSESSMENT OF THE PREVALENCE AND LOCATION OF ROOT RESORPTION IN EPILEPTIC PATIENTS: AN OBSERVATIONAL STUDY
    (2024) Temur, Katibe Tuğçe; Hatipoğlu, Fatma Pertek; Magat, Güldane
    Objective Antiepileptic drugs used in the treatment of epilepsy patients have a negative effect on bone tissue, but as far as we know, tooth root resorption has not been investigated in these patients. The aim of this study was to evaluate the prevalence of external and internal root resorption and its distribution according to resorption sites in epilepsy patients using antiepileptic drugs. Material and Method Panoramic radiographs obtained before dental treatment were evaluated. While the case group consisted of only those with epilepsy, the control group included healthy subjects. The presence/absence of external and internal resorption of all teeth (except the third molars), region of resorption (cervical, middle, and apical region of the root), age, and sex were recorded in an excel file. Independent sample t-test or Mann- Whitney U test according to normality of distribution and a chi-square test to compare categorical variables were used. Results The resorption in 93 (21.9%) of 424 patients (236 healthy subjects and 188 epileptic patients), the groups did not significantly differ by the presence of external and internal resorption (p = 0.089 and 0.746). It was more common in those over 30 years and males (p = 0.018 and 0.013). Conclusion We concluded that the presence of resorption in epilepsy patients was not different from healthy subjects. However, in patients with epilepsy, resorption was mostly seen in the lower molars and middle 1/3 regions. Clinicians should consider our results when treating these patients.
