    The Effect of Dental Pulp Stem Cells and L-PRF When Placed into The Extraction Sockets of Impacted Mandibular Third Molars on The Periodontal Status of Adjacent Second Molars: A Split-Mouth, Randomized, Controlled Clinical Trial
    (2023) Cubuk, Secil; Oduncuoglu, Bahar Fusun; Alaaddinoglu, Emine Elif; https://orcid.org/0000-0001-6718-3882; 35141806; AAH-5405-2020; F-3529-2010
    Purpose To compare the clinical and radiographic effectiveness of dental pulp stem cells (DPSCs) seeded onto L-PRF and L-PRF alone in the extraction socket of mandibular third molars. Methods This study analyzed 13 patients who required surgical removal of impacted bilateral mandibular third molars. The main outcome measures were the probing pocket depth (PPD) and clinical attachment levels (CAL) that were recorded for the adjacent second molars (LM2) at the baseline and 6 months after surgery. The secondary outcomes were radiographic vertical bone loss (VD) and relative bone density (rBD) distal to the LM2. Results Twenty-six LM2s were evaluated. After 6 months, the L-PRF and L-PRF + DPSC groups showed a significant reduction in PPD (1.65 +/- 1.01 mm and 1.54 +/- 0.78 mm) and CAL (2.23 +/- 1.45 mm and 2.12 +/- 0.74 mm), respectively. There was no difference between the groups for any periodontal parameters. No significant differences were found between the groups regarding the VD or rBD at the sixth month. Conclusions This study found that there was a significant improvement regarding the PPD, CAL, and VD measurements with the application of L-PRF, both alone and with the addition of DPSC, at the extraction socket. DPSC did not significantly contribute to the results compared to L-PRF therapy alone.

    Comparative Evaluation of Simultaneous Maxillary Sinus Floor Elevation and Implant Placement with Residual Bone Heights Greater or Less than 5 mm
    (2015) Soydan, Sidika Sinem; Cubuk, Secil; Bayrak, Burcu; Uckan, Sina; 25265126
    Purpose: Implants can be inserted simultaneously during sinus floor elevation (SFE), or 6 months later, for posterior maxillary rehabilitation. The residual bone height (RBH) is a major factor that affects the type of surgical procedure that will be performed. The aim of this study was to compare the survival rates of implants inserted during one-stage SFE with two different RBHs (< 5 mm and >= 5 mm). Materials and Methods: This study consisted of implants inserted into an RBH of either < 5 mm or >= 5 mm, and the survival of the implants was assessed according to the clinical symptoms of the patients: pain or tenderness during function (or spontaneously), mobility, depth of probing, exudation history, and radiographic bone loss at the final follow-up appointment. The survival rates of the two groups were statistically compared using the Fisher exact test. Results: Fifty-nine consecutive patients (29 women and 30 men) undergoing a onestage sinus elevation procedure simultaneously with implant insertion were included in this study. Fifty-one implants were placed in the study group (RBH: 1 to 4.9 mm), and 31 implants were placed in the control group (RBH: 5 to 8 mm). The survival rate of the implants in the study group was 94.2% at the 5.4-year follow-up and 95.8% in the control group at the 7.9-year follow-up. There was no statistically significant difference between the groups in terms of the implant survival rate (P = .785). Conclusion: The results of this study suggest that SFE with simultaneous implant placement in patients with an RBH < 5 mm can be accomplished, and that the survival rate is similar to that of the one-stage SFE protocol with an RBH of > 5 mm.

    A Retrospective Analysis Of Benign Paediatric Jaw Lesions According To New World Health Organization Classification
    (2022) Cubuk, Secil; Colak, Meric Yavuz; 35599042
    The aim of this study was to evaluate the benign paediatric jaw lesions based on the 2017 World Health Organization (WHO) classification. Demographic data, symptoms, radiographic findings, location, size, histopathologic diagnosis, treatment modalities, and outcomes were analysed retrospectively. Recurrence incidence, time to recur, and follow-up time were also evaluated. One hundred seven lesions were diagnosed in 100 patients (44 female, 56 male). The mean follow-up time was 56.6 ?? 45.7 months. The mean age was 12.9 ?? 3.9 years and the majority of lesions were found in the permanent dentition group (p = 0.045). There were 73 patients with odontogenic cysts, followed by 16 patients with odontogenic tumors, and 11 patients with non-odontogenic tumors. Eighty seven lesions (81%) were radiolucent and 93 lesions (86%) were well-circumscribed. The majority of the patients (n = 96) were treated by enucleation. Recurrence was seen in 3 patients. The most notable difference between the results of the present study and the results of the study conducted in medical institutions was the distributions of jaw lesions. Within the limitations of the study it seems that a conservative treatment of benign jaw lesions should be preferred in the paediatric population because this treatment yields acceptable results. ?? 2022 European Association for Cranio-Maxillo-Facial Surgery.

    Incidence of root canal treatment of second molars following adjacent impacted third molar extraction
    (2016) Oguz, Yener; Soydan, Sidika Sinem; Onay, Emel Olga; Cubuk, Secil; 30894952
    Background/purpose: The aim of this study was to evaluate the incidence of requirement for root canal treatment of adjacent second molars following the surgical extraction of an impacted third molar. Materials and methods: The dental records of 6323 consecutive patients who had impacted third molars removed surgically were evaluated and the incidence of postoperative root canal treatment requirement of adjacent second molars was determined. Patients who required root canal treatment of neighboring second molars were accepted as the study group, while the remaining patients were accepted as a control group. Sex, age at the time of the operation, localization of third molar, the depth of impaction, angulation of the tooth, and the professional experience of the surgeon performing the operation were evaluated from patient records. Results: The incidence of requirement of root canal treatment for second molars following a neighboring impacted third molar extraction was 0.17% (11/6323) and invariably occurred in the mandible. The mean age of the study group was found to be significantly higher than the control group (31 years vs. 23 years). The years of professional experience of the surgeons was significantly lower in the study group than in the control group. Conclusion: Although the incidence is minimal, iatrogenic subluxation injuries occurring during the surgical removal of impacted third molars can lead to pulpal complications and a requirement for root canal treatment of adjacent second molars.
