Analysis of the gingival biotype based on the measurement of the dentopapillary complex

Abstract

Background:The gingival morphology of the maxillary anterior region plays an important role in determining the final esthetic outcome. Knowledge of the periodontal biotype is of fundamental importance because the anatomical characteristics of the periodontium, such as gingival thickness, gingival width and alveolar bone morphology, will determine periodontium behavior when submitted to physical, chemical, or bacterial injury or during periodontal or implant surgical procedures and orthodontic treatment.Materials and Methods:50 subjects with healthy periodontal tissues with no loss of attachment and (b) presence of all anterior teeth in both upper and lower jaw were selected. On clinical examination gingival thickness was recorded based on the transparency of periodontal probe. Following parameters are recorded from dental cast, i.e., crown length, crown width, papillary length (PL) and papillary width.Results:There was highly significant correlation between gingival biotype and crown length and area of papilla with P value −0.002 and 0.013 respectively. Significant correlation was found between area of crown and PL with P value −0.013 and 0.016. The results of discriminant function analysis showed that average crown length was the best single determinant of biotype and area of papilla was the next best choice.Conclusion:Within the limits of the current investigation, the existence and correlation of different gingival biotypes and dentopapillary complex dimension has been confirmed. These findings can be utilized as objective guidelines for determining the biotype and response of gingiva to many dental operative procedures.

Quantitative Molecular Detection of 19 Major Pathogens in the Interdental Biofilm of Periodontally Healthy Young Adults

“…The anatomical characteristics of the periodontium, such as gingival thickness, gingival width and alveolar bone morphology, will determine periodontium behavior when it is submitted to physical, chemical, or bacterial injury ( Malhotra et al, 2014 ). The periodontium is mainly the interdental spaces between the molars and premolars, which are susceptible to gingival inflammation ( Kassebaum et al, 2014 ; Eke et al, 2015 ).…”

Distribuição das características clínicas do fenótipo gengival em pacientes saudáveis

“…Outros estudos que reproduziram essa metodologia e que também classificaram os fenótipos em fino ou espesso, concluíram que o teste de transparência à sondagem é um método que, quando devidamente padronizado, é suficientemente reprodutível e confiável 10,[13][14][15][16] . Dentre as principais características encontradas após a determinação dos fenótipos nessas pesquisas, foi visto que o fenótipo gengival fino apresenta tecido mole mais delgado com menor faixa de mucosa ceratinizada, papilas interdentais mais longas e estreitas.…”

“…Dentre as principais características encontradas após a determinação dos fenótipos nessas pesquisas, foi visto que o fenótipo gengival fino apresenta tecido mole mais delgado com menor faixa de mucosa ceratinizada, papilas interdentais mais longas e estreitas. Já o fenótipo espesso foi caracterizado por apresentar maior faixa de mucosa ceratinizada com aspecto denso e fibrótico, bem como papilas mais curtas e largas 10,[13][14][15][16] .…”

Comparative evaluation of soft and hard tissue dimensions in the anterior maxilla using radiovisiography and cone beam computed tomography: A pilot study

“…The thickness of the gingiva is also influenced by the papillary height,[ 12 ] crown width and height ratio, and the width of keratinized gingiva. [ 13 ] The gingival thickness in this study was found to increase from G1 to G4.…”
