Conclusions Cord and paste retraction produced comparable clinically acceptable gingival gaps, with the cord producing statistically larger gap size. Clinical significance The cord and paste retraction materials produced comparable clinically acceptable gingival retraction.Class III malocclusion is a common dentofacial deformity. The underlying genetic alteration is largely unclear. In this study, we sought to determine the genetic etiology for class III malocclusion. A 4-generation pedigree of class III malocclusion was recruited for exome sequencing analyses. The likely causative gene was verified via Sanger sequencing in an additional 90 unrelated sporadic class III malocclusion patients. We identified a rare heterozygous variant in ERLEC1 (NM_015701.4(ERLEC1_v001)c.1237C>T, p.(His413Tyr), designated as ERLEC1-m in this article) that co-segregated with the deformity in pedigree members and three additional rare missense heterozygous variants (c.419C>G, p.(Thr140Ser), c.419C>T, p.(Thr140Ile) and c.1448A>G, p.(Asn483Ser)) in 3 of 90 unrelated sporadic subjects. Our results showed that ERLEC1 is highly expressed in mouse jaw osteoblasts and inhibits osteoblast proliferation. ERLEC1-m significantly enhanced this inhibitory effect of osteoblast proliferation. Our results also showed that the proper level of ERLEC1 expression is crucial for proper osteogenic differentiation. The ERLEC1 variant identified in this study is likely a causal mutation of class III malocclusion. Our study reveals the genetic basis of class III malocclusion and provides insights into novel target for clinical management of class III malocclusion in addition to orthodontic treatment and orthodontic surgery.
