Correlation between newly formed bone and the progression of experimental peri-implantitis with or without alveolar ridge preservation in infected and non-infected teeth: a secondary analysis of a preclinical study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeWe examined the progression of experimental peri-implantitis in sites that underwent either alveolar ridge preservation (ARP) or spontaneous healing (SH), comparing infected teeth (IT) and non-infected teeth (NIT). This investigation is a secondary analysis of a preclinical study aimed at exploring the correlation between newly formed bone and implant stability quotient (ISQ), as well as the association between newly formed bone and the progression of experimental peri-implantitis.
methodsThe bilateral mandibular third or fourth premolars of 6 beagle dogs were randomly assigned to 4 groups: IT/SH, IT/ARP, NIT/SH, and NIT/ARP. Following implant placement, core biopsies were retrieved from each site, and the ISQ value was measured. A 3-month period was allowed for peri-implantitis induction, followed by an additional 3 months for the spontaneous progression of peri-implantitis, with radiographs taken at each time point.
resultsDuring the spontaneous progression of peri-implantitis, no statistically significant differences were observed among the groups in terms of mean ISQ values and radiographic marginal bone loss. Similarly, the percentages of bone substitute, newly formed bone, and fibrovascular connective tissue in core biopsies did not differ significantly among the groups. Linear regression analysis revealed no significant linear correlation between newly formed bone and ISQ in any group (
conclusionsWithin the limitations of this study, we were unable to demonstrate that ARP could improve newly formed bone or primary implant stability. Furthermore, neither ARP nor SH significantly influenced the spontaneous progression of experimental peri-implantitis.
