Class III KMs have been reported previously; however, reports on class III KMs in young people (&lt;\u200918\u00a0years of age) are limited.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>Here, we present the case of KMs class III confirmed at an early age, supported by a review of the literature. The patient was a 16-year-old female and experienced discomfort in the left molar of the lower jaw and visited in our department. We diagnosed KMs based on an impacted teeth on the buccal side, near the lower jaw wisdom teeth, and a cyst-like low-density area observed around the crown of both teeth, as revealed by computed tomography. We decide to extract the tooth and enucleate the cyst under local anesthesia as the patient experienced discomfort due to occlusion. Furthermore, the cyst-like structure removal and tooth extraction including tooth root were necessary as the patient had KM class III, possibly inducing complicated malocclusion. Although no previous reports recommended timing for KMs tooth extraction, we propose that extraction at an early stage is important regardless of age especially in class III cases.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>We report a case of KM class III detected at an early age.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40902-023-00388-4","type":"journal-article","created":{"date-parts":[[2023,5,23]],"date-time":"2023-05-23T04:03:20Z","timestamp":1684814600000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Kissing molars class III detected at a young age"],"prefix":"10.1186","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4511-6010","authenticated-orcid":false,"given":"Teruhide","family":"Hoshino","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Koyama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akira","family":"Katakura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,5,23]]},"reference":[{"key":"388_CR1","first-page":"118","volume-title":"Difficult tooth extraction; clinical of tooth extraction","author":"N Hiroyasu","year":"1991","unstructured":"Hiroyasu N, Yuzuru K (1991) Difficult tooth extraction; clinical of tooth extraction, 1st edn.
