Gingival Biotype and Morphometric Data Related to Maxillary Central Incisors in a University Student Population
Assaf, Mohammad / Alshalakh, Shayma / Aliwaiwi, Fidaa / Qawasmeh, Samah / Alaraj, Tamara
Aim: To evaluate the distribution of gingival biotype based on transparency of the periodontal probe among a
Palestinian population and correlation with morphometric data related to maxillary central incisors and
surrounding soft tissues.
Material and Methods: Among the senior dental students at Al-Quds University, Palestine; fourty-four volunteers with healthy periodontium
and absence of any restorations or history of orthodontic treatment were evaluated. Clinical parameters related to
both maxillary central incisors included: Crown width/crown length ratio (CW/CL), gingival width (GW), probing
depth (PD), and gingival thickness (GT). A periodontal probe was inserted in the midbuccal sulcus of the incisor to
visually evaluate if it had a thin or thick gingival biotype.
Results: The study involved 32 females and 12 males; all their ages ranged between 22 and 24 years. Although clinical
parameters of CW/Cl, GW, and PD were all smaller in females (0.76, 5.75 mm, and 1.47 mm, respectively); none
of them were significantly different from males (0.80, 5.9 mm, and 1.64 mm, respectively). Three clusters where
determined: cluster A (eight females, four males) for clear thin-scalloped gingiva, cluster B (fifteen females, four
males) for cases where it was unclear to be neither thin-scalloped nor thick-flat, and cluster C (nine females, four
males) for clear thick-flat gingiva. Clinical parameters of CW/Cl, GW, and PD were all statistically significantly
different between clusters A and B.
Conclusion: Nearly one-third of the examined population had clear thin-scalloped gingiva with similar portion for thick-flat
gingiva. Positive correlation is present between thick-flat gingival and greater clinical parameters of CW/CL, GW,
and PD.
