In the multivariable analysis, financial influence remained the only significant predictor of material choice, whereas gender, clinical experience, postgraduate training and perceived social media influence were not independent determinants. Composite resin was preferred for premolars and aesthetically driven cases, whereas amalgam was favoured for molars and for patients with poor hygiene or inadequate moisture control. HVGICs were selected for mainly children (60%) and elderly patients (39%). Most dentists perceived that social media strongly influenced their patients\u2019 preferences (p<0.0001), with 97% of dentists reporting believing that their patients\u2019 preferences were due to social media.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n Patient-related factors were the main determinants of material selection, whereas practitioner demographics played a minimal role. HVGICs are preferred for paediatric and elderly patients because of their suitability for age-specific clinical needs. The influence of social media, assessed in this study as dentists\u2019\n perceptions<\/jats:italic>\n rather than direct measures of patient behaviour, underscores its growing role in shaping dentists\u2019 impressions of patient expectations and highlights the importance of evidence-based guidance and public education to support patient-centred, clinically appropriate restorative decisions.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1136\/bmjopen-2025-103609","type":"journal-article","created":{"date-parts":[[2026,4,2]],"date-time":"2026-04-02T16:10:22Z","timestamp":1775146222000},"page":"e103609","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Factors influencing dentists\u2019 choice of restorative materials for occlusal cavities: a cross-sectional study from Palestine"],"prefix":"10.1136","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5961-6975","authenticated-orcid":false,"given":"Naji Ziad","family":"Arandi","sequence":"first","affiliation":[{"name":"Faculty of Dentistry, Department of Conservative Dentistry, Arab American University, Jenin, Palestine, State of"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,4,2]]},"reference":[{"key":"2026040209101852000_16.4.e103609.1","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1016\/S1646-2890(10)70005-4","article-title":"A Review of Amalgam and Composite Longevity of Posterior Restorations","volume":"51","author":"Soares","year":"2010","journal-title":"Revista Portuguesa de Estomatologia, Medicina Dent\u00e1ria e Cirurgia Maxilofacial"},{"key":"2026040209101852000_16.4.e103609.2","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1177\/23202068221114979","article-title":"A Systematic Review and Meta-Analysis of the Success of Resin Composite Restorations","volume":"13","author":"K\u00f6l\u00fc\u015f","year":"2022","journal-title":"Journal of Advanced Oral Research"},{"key":"2026040209101852000_16.4.e103609.3","doi-asserted-by":"crossref","unstructured":"Worthington H , Khangura S , Seal K , et al . permanent posterior teeth.
