The Planas Functional Masticatory Angle [PFMA] is a functional parameter describing mandibular trajectory during mastication. Its variation across dentition stages may reflect cross-sectional physiological functional adaptation during growth. Methods. A cross-sectional pilot study recruited 30 patients [10 per group: deciduous, mixed, permanent dentition] from a university dental clinic. PFMA was measured using a standardized intraoral photographic protocol, with intra-examiner reliability assessed [ICC &gt; 0.9]. Molar relationships were classified per Angle\u2019s classification. PFMA differences across dentition stages were analyzed using one-way ANOVA, and molar class distributions were evaluated with chi-square tests [p &lt; 0.05]. Results. PFMA values decreased significantly from deciduous [64.7\u00b0 \u00b1 6.9] to mixed [55.5\u00b0 \u00b1 7.8] and permanent dentition [47.2\u00b0 \u00b1 9.8] [ANOVA, p &lt; 0.001]. Post hoc analysis revealed significant differences between deciduous and permanent stages. No significant right\u2013left PFMA differences were observed. Class I molar relationships predominated [70%], and no significant association was found between PFMA and molar class. Conclusions. This pilot study suggests PFMA decreases with dentition progression, reflecting physiological occlusal adaptation. Class I predominance supports functional symmetry, but PFMA-molar class associations require larger samples. Longitudinal studies are needed to further explore the clinical applicability of PFMA as a functional descriptor of masticatory adaptation.<\/jats:p>","DOI":"10.3390\/dj14040213","type":"journal-article","created":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T09:40:31Z","timestamp":1775554831000},"page":"213","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of the Planas Functional Masticatory Angle Across Deciduous, Mixed, and Permanent Dentition Stages: A Cross-Sectional Pilot Study"],"prefix":"10.3390","volume":"14","author":[{"given":"Gema","family":"Torres-Romero","sequence":"first","affiliation":[{"name":"Faculty of Medicine and Health Sciences, Catholic University of Valencia, San Vicente Martir, 46001 Valencia, Spain"},{"name":"Department of Dentistry, Faculty of Medicine and Health Sciences, European University of Valencia, 46010 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8841-7975","authenticated-orcid":false,"given":"Clara","family":"Guinot-Barona","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Sciences, Catholic University of Valencia, San Vicente Martir, 46001 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7360-2609","authenticated-orcid":false,"given":"Lidia","family":"Gal\u00e1n-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Sciences, Catholic University of Valencia, San Vicente Martir, 46001 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5722-0547","authenticated-orcid":false,"given":"Laura","family":"Marqu\u00e9s-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Sciences, Catholic University of Valencia, San Vicente Martir, 46001 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8864-3702","authenticated-orcid":false,"given":"Esther","family":"Garcia-Miralles","sequence":"additional","affiliation":[{"name":"Dentistry Department, Faculty of Medicine and Dentistry, University of Valencia, 46010 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0054-1005","authenticated-orcid":false,"given":"Juan Ignacio","family":"Aura-Tormos","sequence":"additional","affiliation":[{"name":"Dentistry Department, Faculty of Medicine and Dentistry, University of Valencia, 46010 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,7]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2013).
