KATHLEEN BLAKE vs. SUZANNE AVEDIKIAN & another. [Note 1]

LYNCH, J. On the plaintiff's complaint, alleging dental malpractice, a malpractice tribunal (G. L. c. 231, Section 60B [1990 ed.]) determined that there was not sufficient evidence to raise a legitimate question of liability appropriate for judicial inquiry. The plaintiff's motion for reconsideration and motion to strike the decision of the tribunal were denied. The Superior Court dismissed her complaint after she failed to post the required bond, and the plaintiff appealed. The Appeals Court affirmed the dismissal in an unpublished memorandum and order pursuant to Appeals Court Rule 1:28. 31 Mass. App. Ct. 1103 (1991). We granted the plaintiff's application for further appellate review, and now reverse the judgment with respect to Dr. Avedikian, but affirm the judgment with respect to Dr. Killilea.

The defendants argue that the tribunal's determination was correct because the plaintiff's offer of proof was insufficient. "A plaintiff's offer of proof as to negligence will prevail before a malpractice tribunal . . . (1) if a doctor-patient relationship is shown, (2) if there is evidence that the doctor's performance did not conform to good medical practice, and (3) if damage resulted therefrom." Kapp v. Ballantine, 380 Mass. 186, 193 (1980). The defendants argue that: the plaintiff failed to establish the qualifications of her proffered expert; the expert's opinion letter failed to identify any standards of dental practice to which the defendants' performance did not conform; and that the plaintiff failed to establish a doctor-patient relationship with Dr. Killilea.

1. Qualification of expert. The standard for admission of expert testimony before a medical malpractice tribunal is

"extremely lenient," Halley v. Birbiglia, 390 Mass. 540, 543 n.4 (1983).

"In our view, the tribunal should give consideration to the proffered opinion of an expert if the offer of proof is sufficient to show that a trial judge in his discretion might properly rule that the qualifications of the witness are sufficient [emphasis in original]. Thus, the opinions of an expert are to be received even if the tribunal (or its presiding judge) might decide that if the exercise of discretion were in its province, it would not accept the expert as qualified" (emphasis added). Kapp v. Ballantine, 380 Mass. 186, 192 (1980). Furthermore, we note that any challenge to the credentials of an expert should not be made for the first time on appeal. Halley v. Birbiglia, supra. [Note 2]

The defendants argue that the plaintiff failed to establish her proffered expert as qualified to give an opinion because no information was supplied as to the expert's education, training, knowledge, or professional experience. We have stated that the "extent of [an expert's] training and experience would bear only on the weight that should be given to his testimony," Commonwealth v. Schulze, 389 Mass. 735, 740 (1983), and not its admissibility. See Letch v. Daniels, 401 Mass. 65, 69 (1987). Appraisal of the weight and credibility of the evidence by the tribunal is impermissible. Kapp v. Ballantine, supra at 191. A judge may disqualify the expert at trial, but a tribunal may not, if minimal evidence exists as to the expert's qualifications. Id. at 192.

The opinion letter supplied by the plaintiff's expert, Dr. Stephen P. Straus, was typed on the letterhead of a professional dental association and the expert's name, followed by the abbreviation, "D.M.D.," was imprinted on the letterhead. The letter was signed by Dr. Straus with the same abbreviation after his signature and in the signature block. Although it would have been preferable for the plaintiff to have submitted an affidavit with supporting documentation as to the

expert's credentials, we conclude that the letter, as submitted, satisfied the plaintiff's burden of showing that Dr. Straus was a practicing dentist and, therefore, met the "extremely lenient" standard of establishing an expert's qualifications before a medical malpractice tribunal.

2. Conformance to good medical practice. The defendants argue that the plaintiff's offer of proof was insufficient to show that the defendants failed to conform to good medical practice. In a proceeding before a medical malpractice tribunal the evidence presented by the offer of proof is viewed by a standard comparable to a motion for a directed verdict, that is, in a light most favorable to the plaintiff. Kopycinski v. Aserkoff, 410 Mass. 410, 415, 417-418 (1991).

The plaintiff's offer of proof included a letter from her expert and pre- and postoperative photographs. The defendants argue that the letter sets forth merely conclusory opinions. The plaintiff argues that the letter identifies a dental standard; that care must be taken to bend back and preserve the gum which is attached to the tooth to be extracted, and that the standard was not met. We agree. [Note 3] Assuming the plaintiff's expert is properly qualified at trial, the letter, supported by the photographs, satisfies the requirements set out in Kapp, supra, with respect to Dr. Avedikian. [Note 4]

3. Doctor-patient relationship. The plaintiff's complaint did not expressly allege a doctor-patient relationship with Dr. Killilea. Even if it had, without more, such allegation would not be enough. We have stated that "Section 60B, albeit imprecise, plainly requires the plaintiff to do more than simply plead facts constituting a legal cause of action. The statute instructs the tribunal to `determine if the evidence presented . . . is sufficient to raise a legitimate question of liability appropriate for judicial inquiry'. . . . Indeed, the statute goes further by expressly delineating possible sources of admissible evidence . . . ." (Emphasis supplied.) Little v. Rosenthal, 376 Mass. 573, 578 (1978). The plaintiff here presented no evidence of a doctor-patient relationship with Dr. Killilea. The plaintiff argues in her brief that her offer of proof asserted that Dr. Killilea assisted Dr. Avedikian in extracting her tooth after it had been broken. [Note 5] Such assertion by the plaintiff's attorney is not evidence of a doctor-patient relationship. The defendants made no admissions as to a doctor-patient relationship with respect to Dr. Killilea. Contrast note 4, supra. Nothing in the opinion letter of the plaintiff's expert can be construed as addressing Dr. Killilea's alleged performance. The plaintiff's offer was defective as to Dr. Killilea.

The judgment of the Superior Court in favor of Dr. Avedikian is reversed; the judgment dismissing the action against Dr. Killilea is affirmed.

So ordered.
