A case study evaluating the effect of clustering, publication bias, and heterogeneity on the meta analysis estimates in implant dentistry
(2023) Atieh, Momen A.
Abstract: Meta-analyses may provide imprecise estimates when important meta-analysis parameters are not considered during the synthesis. The aim of this case study was to highlight the influence of meta-analysis parameters that can affect reported estimates using as an example pre-existing meta-analyses on the association between implant survival and sinus membrane perforation. PubMed was searched on 7 July 2021 for meta-analyses comparing implant failure in perforated and non-perforated sinus membranes. Primary studies identified in these meta-analyses were combined in a new random-effects model with odds ratios (ORs), confidence intervals (CIs), and prediction intervals reported. Using this new meta-analysis, further meta-analyses were then undertaken considering the clinical, methodological, and statistical heterogeneity of the primary studies, publication bias, and clustering effects. The meta-analyses with the greatest number and more homogeneous studies provided lower odds of implant failure in non-perforated sites (OR 0.49, 95 % CI = [0.26, 0.92]). However, when considering heterogeneity, publication bias, and clustering (number of implants), the confidence in these results was reduced. Interpretation of estimates reported in systematic reviews can vary depending on the assumptions made in the meta-analysis. Users of these analyses need to carefully consider the impact of heterogeneity, publication bias, and clustering, which can affect the size, direction, and interpretation of the reported estimates.
Changes in oral home care and smoking habits during COVID‐19 pandemic: A cross‐sectional study
(2024) Atieh, Momen A.; Aldhanhani, Afrah; Shah, Maanas
Objectives: The coronavirus disease‐19 (COVID‐19) pandemic has caused disruption in the health behavior in many aspects of life. While hand hygiene was promoted as one of the precautionary measures to mitigate and contain COVID‐19, oral health and smoking might have received less attention in the media campaigns. The aim of this study was to examine health behavioral changes in terms of oral home care habits, smoking, and perception of dental care during the COVID‐19 pandemic. Material and Methods: An online survey was designed to assess oral home care, smoking habits, and attitude toward dental services of participants aged 18 years and older. The data were collected between September and November 2021. The strength of association between changes in oral home care habits, smoking, and attitude toward invasive/long dental procedures and each variable was measured by χ 2 analysis. Estimates of relative risk were also calculated for all variables. Predictors of avoiding dental procedures were estimated by a binary logistic regression. Results: A total of 532 participants, based in the United Arab Emirates, took part in this online survey with a response rate of 88.7%. The age of the participants ranged between 18 and 67 with mean age of 34.9 ± 9.0 years. The majority of the participants have adopted changes in their routine oral home care habits, with 82.1% of them changing the toothbrush more frequently. Participants who changed their oral home care habits were more likely to have received sufficient information on the importance of maintaining oral health. Likewise, the changes in smoking habits were significantly associated with receiving information on the relationship between smoking and the severity of the COVID‐19 (p < 0.001). Conclusions: The findings showed that positive behavior toward oral home care and smoking was noticed during the pandemic particularly when public receives sufficient and up‐to‐date information.
Enamel matrix derivative for alveolar ridge preservation: A randomized controlled trial
(2023) Atieh, Momen A.; Al-Ali, Bashayer; Shah, Maanas; Amir-Rad, Fatemeh; Baqain, Zaid H.; Al-Suwaidi, Salem
Objective: The aims of this clinical trial were to evaluate the radiographic dimensional changes in alveolar ridge and patient-reported outcomes following tooth extraction and alveolar ridge preservation (ARP) using either deproteinized bovine bone mineral (DBBM) with EMD or DBBM alone. Methods: Participants requiring at least one posterior tooth extraction and ARP were randomly allocated into two treatment groups: ARP using either DBBM with EMD or DBBM alone. Cone-beam computed tomography (CBCT) images were recorded immediately prior to extraction and at 6 months. Changes in alveolar ridge height (ARH) and alveolar ridge width (ARW) at 1, 3, and 5 mm were recorded. Results: A total of 18 participants with 25 preserved sites were evaluated. ARH and ARW changed significantly from baseline to 6 months for both treatment groups but the difference between the groups was not statistically significant over the 6-month follow-up period (ARH: DBBM/EMD 1.26 ± 1.53 mm vs. DBBM 2.26 ± 1.60 mm; ARW-1 DBBM/EMD 1.98 ± 1.80 mm vs. DBBM 2.34 ± 1.89 mm). A significant difference, favoring DBBM with EMD group, was observed in percentage of sites that had less than 1 mm loss in ARH (54.5% sites in DBBM/EMD group vs. 14.3% sites in DBBM alone group). The participants' perception of bruising, bleeding, and pain in the first two postoperative days was significantly in favor of DBBM alone group. Conclusions: There were no significant differences in radiographic mean measurements of ARH and ARW following ARB with DBBM and EMD or DBBM alone.
Peri-implantitis Through the Looking Glass
(2023) Atieh, Momen A.
Introduction: The states of health and disease are inseparable, as the existence of one relies on the presence of the other. The definitions of health and disease in medicine and dentistry have evolved over the years from ones that are patient-centred to a complex set of terminology that has resulted in communication ambiguity. An example of such are “peri-implant diseases,” a lingering topic in the current literature.
Response to letter to the editor: Re: Stability of tapered and parallel-walled dental implants: A systematic review and meta-analysis
(2023) Atieh, Momen A.
Introduction: The primary aim of our systematic review and meta-analysis was to assess the implant stability of tapered dental implants compared to standard parallel-walled dental implants.1 The peri-implant marginal bone level changes were one of the secondary outcomes which was only evaluated in two studies.2,3 The meta-analysis showed that tapered dental implants had less peri-implant marginal bone loss compared to parallel-wall dental implants (mean difference ̶ 0.28; 95% confidence interval ̶ 0.55 to ̵ 0.01; p = 0.04). Heterogeneity was detected (Chi2 = 2.06, df = 1 (p = 0.15); I 2 = 52%).
