Psychiatry Investigation 2021;18(7):593-602
Objective:
To evaluate the relationship between grandparenting and the cognitive impairment in older persons.
Methods:
The protocol was submitted to the International Prospective Register of Systematic Reviews (PROSPERO), registration number: CRD42018105849. Authors conducted a systematic review, following “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” (PRISMA) recommendations. Electronic databases were accessed through august 2018: PubMed, ISI Web of Knowledge, Scopus, and EBSCOhost. Selection of records and quality appraisal were made by two reviewers, independently.
Results:
A total of 178 records was found, after removing duplicates. From those, 17 were considered eligible for integral text reading and eight were included: five original studies, one classic review and two editorials. From the five original studies included, four suggested a positive effect on cognition resulting from grandparenting and one suggested that there was no evidence for a causal effect. Though the boundary was not consensual, some studies suggested that a higher frequency of grandparenting has a negative impact on cognition.
Conclusion
Overall, studies suggested a trend towards a positive effect of grandchild care on grandparents’ cognition. However, there was a significant heterogeneity between methodologies and a significant risk of bias which can hamper conclusions, indicating the need for further and more robust research.

OBJECTIVE:
This study aimed to identify possible risk factors for external apical root resorption (EARR) in the maxillary incisors after orthodontic treatment.
METHODS:
The root length of 2,173 maxillary incisors was measured on periapical radiographs of 564 patients who received orthodontic treatment. The Kappa test was performed to evaluate intraexaminer and interexaminer reproducibility. Multiple binary logistic regression was used to determine the association between EARR and various factors. Odds ratios and 95% confidence intervals were reported.
RESULTS:
The risk of developing EARR was 70% higher in orthodontic treatment with maxillary premolar extraction (p = 0.004), 58% higher in patients with increased overjet (p = 0.012), 41% lower in two-phase orthodontic treatment (p = 0.037), and 33% lower in patients with deep bite (p = 0.039). The lateral incisors were 54% more likely to develop EARR (p < 0.001), dilacerated roots were 2.26 times more likely to develop EARR (p < 0.001), and for each additional millimeter of root length, the risk of EARR increased by 29% (p < 0.001).
CONCLUSIONS
The potential risk factors for EARR after orthodontic treatment included treatment with maxillary premolar extraction, increased overjet at the beginning of treatment, and dilacerated roots.
