This paper is a systematic review of low-level laser therapy used as an adjunct for orthodontic retention, incorporating both human and animal studies and focusing on outcomes related to orthodontically induced inflammatory root resorption. The key reported contribution is that the authors synthesized evidence on low-level laser therapy’s effects in this retention context, but the preprint itself is withdrawn due to author disagreement, limiting confidence in its conclusions. A major caveat is the withdrawn status and the limited extractable methodological/results details provided in the available text. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.
