The purpose of this study is to assess the relationship between twin pairs\u2019 birth weight, gestational age, and gender, which are indicators of prenatal factors; breast-feeding duration, which is an indicator of postnatal factors; type of delivery, which is an indicator of maternal as well as genetic factors; and age of the primary tooth. Twin children aged from 3 to 15 years who applied to the clinic for the first dental examination constituted the sample group. In this twin study, 59 monozygotic (MZ) twin pairs and 143 dizygotic (DZ) twin pairs were included. Genetic (MZ vs. DZ), maternal (type of delivery, gestational age), perinatal (birth weight, gender), and postnatal (duration of breastfeeding) information was obtained, and effects on the children\u2019s Eruption Timing of the First Primary Tooth (ETFPT) were examined. Statistical analysis was performed using the consistent partial least squares structural equation model (robust PLSc) technique. As birth weight increased, the age at first eruption became younger, but this change was different between MZ and DZ twins (p &lt; 0.05). While the age at first tooth eruption was older in identical twins who were breastfed for the first 6 months, this increase was not observed in DZ twins. The mean of ETFPT was calculated as 7.31 months in MZ twins and 6.75 months in DZ twins. The effect of breastfeeding and birth weight on ETFPT may differ according to zygosity in twins. MZ twins may tend to take longer to experience the eruption of their first primary teeth.<\/jats:p>","DOI":"10.3390\/children10040683","type":"journal-article","created":{"date-parts":[[2023,4,4]],"date-time":"2023-04-04T02:30:15Z","timestamp":1680575415000},"page":"683","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Path Analysis of the Relationships between the Eruption Time of the First Primary Teeth and Various Factors in Twins"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3990-7270","authenticated-orcid":false,"given":"Sinem","family":"Birant","sequence":"first","affiliation":[{"name":"Department of Pedodontics, Faculty of Dentistry, Istanbul University-Cerrahpasa, Istanbul 34098, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0713-1313","authenticated-orcid":false,"given":"Mert","family":"Veznikli","sequence":"additional","affiliation":[{"name":"Department of Statistics, Faculty of Science and Arts, Yildiz Technical University, Istanbul 34220, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yelda","family":"Kasimoglu","sequence":"additional","affiliation":[{"name":"Department of Pedodontics, Faculty of Dentistry, Istanbul University, Istanbul 34452, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2077-5095","authenticated-orcid":false,"given":"Mine","family":"Koruyucu","sequence":"additional","affiliation":[{"name":"Department of Pedodontics, Faculty of Dentistry, Istanbul University, Istanbul 34452, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"At\u0131f Ahmet","family":"Evren","sequence":"additional","affiliation":[{"name":"Department of Statistics, Faculty of Science and Arts, Yildiz Technical University, Istanbul 34220, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Figen","family":"Seymen","sequence":"additional","affiliation":[{"name":"Department of Pedodontics, Faculty of Dentistry, Altinbas University, Istanbul 34218, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"28","DOI":"10.24018\/ejdent.2021.2.3.63","article-title":"The impact of maternal, perinatal and early infancy period on the eruption timing of the first primary tooth","volume":"2","author":"Georgiadou","year":"2021","journal-title":"Eur.
