In an action to recover damages for dental malpractice, defendant appeals from an order of the Supreme Court, Queens County (Leviss, J.), dated August 5, 1983, which granted plaintiff's motion to restore the case to the Trial Calendar. ¶ Order reversed, on the law, without costs or disbursements, and plaintiff's motion denied, without prejudice to renewal upon proper papers. ¶ It has been held that plaintiffs have the burden, in attempting to restore a case the the Trial Calendar, to establish merit, lack of prejudice to defendants and a reasonable excuse (see Spodek v Lasser Stables, 89 A.D.2d 892; Horn v Schenck Transp. Co., 65 A.D.2d 589; Ruggerio v Elbin Realty, 51 A.D.2d 1011). ¶ With respect to the issue of merit, it was incumbent for the plaintiff herein who is alleging a cause of action based on dental malpractice, to submit an affidavit containing evidentiary facts by a person competent to attest to the meritorious nature of her claim, i.e., a dental expert (see Hatcher v City of New York, 99 A.D.2d 481; Berman v Brunswick Hosp. Center, 94 A.D.2d 736; Ferrigno v St. Charles Hosp., 86 A.D.2d 594; Sussman v Franklin Gen. Hosp., 77 A.D.2d 567; Sortino v Fisher, 20 A.D.2d 25, 32; Keating v Smith, 20 A.D.2d 141). In the absence of such an affidavit, Special Term erred in granting plaintiff's motion to restore the case to the Trial Calendar. Mangano, J.P., Thompson, O'Connor and Boyers, JJ., concur.
