Maxillary posterior gingiva and teeth displayed influence smile attractiveness: study

Results:

• The VAS scores of participants with high PSL were significantly lower than those with average or low PSL (P < .01), especially when they display average or low anterior smile line (P < .05).
• Smiles with the second premolar displayed obtained the highest VAS amongst the 3 subgroups (P < .05).
• No significant differences were found between the VAS scores of BCR and BCS (P > .05).

Thus, maxillary posterior gingiva and teeth displayed influence smile attractiveness evaluated by laypersons, which should be given attention when treating patients with compromised aesthetics, especially those displaying average or low anterior smile lines.
