Introduction:
The aim of this systematic review was to evaluate the pooled estimate and relative risk of periapical lesions in natural teeth adjacent to implants.
Methods:
MEDLINE (PubMed), Embase, Cochrane Library, and gray literature were searched (inception-November 2023) to identify studies. Eligible studies were selected and data extracted. Studies were critically assessed for risk of bias and quality of evidence. Quantitative analysis was performed to determine the pooled estimate of periapical radiolucent lesions (PARLs) in teeth adjacent to implants and to assess the relative risk of developing such lesions in these teeth compared to teeth adjacent to nonimplants.
Results:
A total of 6 studies were included. The pooled estimate of PARL in implant adjacent teeth was 2.55%. The risk ratio for PARL in a tooth adjacent to an implant in comparison to a tooth adjacent to a nonimplant was 2.12. Analyses presented low certainty of evidence.
Conclusions:
A natural tooth adjacent to an implant has 2.12 times higher probability of developing a PARL compared to a tooth adjacent to a nonimplant. The overall quality of evidence was low.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
