    Effect of sonic irrigation activation at different frequencies in smear layer removal; An in vitro ‎experimental study
    (2022) Aalmohamed, Eiman; Ahmed, Fatemeh; Alfardan, Layal; El Abed, Rashid; Hassan Khamis, Amar; Jamal, Mohamed
    Introduction: The aim of this study was to compare the vibration/oscillation frequencies of WaterPik and ‎EndoActivator devices and their effectiveness in smear layer (SL) removal.‎ Materials and Methods: The root canal of 60 single‑rooted extracted human premolars were prepared until ProTaper Universal F2 ‎file, and randomly grouped according to the irrigation activation technique used: EndoActivator group; ‎WaterPik group; manual dynamic agitation (MDA) group; and control group (conventional irrigation with ‎no activation). The vibration/oscillation frequencies of EndoActivator and WaterPik devices were ‎measured using a digital tachometer. Electron microscopy images of all specimens were evaluated for ‎SL removal according to a modified Hülsmann scoring system. Data were statistically analyzed.‎ Results: The mean vibration frequency of the EndoActivator was significantly higher than that of WaterPik (200.6 ‎‎± 2.1 and 185.2 ± 2.744 Hz, respectively). A significant difference was detected in the SL removal along ‎the full length of the canal between the experimental and control groups (P ˂ 0.001). EndoActivator and ‎MDA groups had significantly more samples with no to minimum SL at the coronal and middle thirds ‎compared to the apical third, whereas there was no significant difference among the thirds in the ‎WaterPik group. At the apical third, the WaterPik group had significantly more samples with no to ‎minimum SL (60%) than WaterPik and MDA groups (20% and 26.7%, respectively).‎ Conclusion: WaterPik was as effective as MDA and EndoActivator in SL removal, with better performance at the ‎apical third, probably attributed to the lower vibration/oscillation frequency of WaterPik.‎

    Flapped versus flapless alveolar ridge preservation: a systematic review and meta-analysis
    (2021) Atieh, Momen; Alfardan, Layal
    Abstract: Alveolar ridge preservation (ARP) procedures can limit bone changes following tooth extraction. Flapped and flapless surgical approaches have been used for ARP; however, there is a lack of strong scientific evidence regarding their specific influences on the clinical outcomes of ARP. The aim of this systematic review and meta-analysis was to evaluate the effects of flapped and flapless surgical approaches on the dimensional changes of hard and soft tissues and patient-reported outcomes following ARP. Electronic databases were searched to identify randomized controlled trials (RCTs) that compared flapped ARP by means of a coronally advanced flap to flapless ARP where barrier membranes were left exposed. The risk of bias was assessed using the Cochrane Collaboration Risk of Bias tool. Data were analysed using a statistical software program. A total of 754 studies were identified, of which five studies with 149 extraction sockets in 128 participants were included. Overall, meta-analysis did not show any significant differences in the changes in ridge width or height between flapped and flapless ARP. The use of flapless ARP was associated with significantly less postoperative pain, thicker labial soft tissues, and marginally more favourable changes in width of the keratinized tissues compared to the flapped approach. The short-term hard tissue changes following ARP with a flapped or flapless approach are comparable. Postoperative pain and labial soft tissue changes are more favourable following ARP using a flapless approach. Further evidence from long-term RCTs is still required to substantiate the current findings.
