Review Meta Analysis
Evaluation of maxillary anterior teeth width: A systematic review.
Estimating the width of the maxillary anterior teeth when creating an esthetic smile can be challenging. Valid metrics to assist in this process are needed. ⋯ By analyzing the data from the literature, only the recurring esthetic dental proportion (70%) with interalar distance could be an accurate method for predicting the combined width of central incisors. Neither interalar distance nor inner canthal distance could directly be used to predict the intercanine distance.

Meta Analysis
Risk of bias assessment of systematic reviews regarding dental implant placement in smokers: An umbrella systematic review.
Although dental implant treatment has a high success rate, patient-related factors may cause implant failure. In this context, smoking is associated with adverse effects on implant osseointegration. In spite of systematic reviews addressing this topic, the risk of bias in these reviews must be assessed to inform readers whether the studies were conducted with methodological rigor and whether their recommendations are viable in daily clinical practice. ⋯ Five of the 6 included meta-analyses had a risk of bias (high or unclear). Therefore, their conclusions and recommendations required careful review. Future meta-analyses must focus especially on study eligibility criteria and identification and selection of studies.
