MATERIAL AND METHODS: An electronic survey was sent to a sample of dentists practicing in Spain. The questionnaire was based on the evaluation of 5 cases involving different gingival biotype assessment methods. Dentists were required to classify the cases as having a 'thin', 'thick' or 'not able to classify' biotype. Each case was assessed using a frontal intraoral photo of the anterior teeth; an enlarged photo of the buccal aspect of the tooth with a periodontal probe inserted inside the sulcus; and the real thickness measured in mm with a calibrated needle. Agreement among the classifications was assessed using Cohen's kappa coefficient. RESULTS: A total of 104 surveys were analyzed. The most commonly used assessment method was visual evaluation of the morphology of the gingiva and the teeth (62.5%). Concordance among the three different methods was weak (kappa = 0.278). Agreement among the classification methods was greater in extreme cases (thinner and thicker gingival thickness). CONCLUSIONS: The most commonly used methods for assessing gingival biotype are not reliable. The three tested methods show poor to weak agreement, which leads to non-reliable estimation of the gingival biotype.1 p.application/pdfeng(c) Medicina Oral SL, 2020Malalties de les genivesOdontologiaGum diseasesDentistryinfo:eu-repo/semantics/article6955962020-11-09info:eu-repo/semantics/openAccess31880279
