A former restaurant worker who alleged work by two dentists 鈥� including one who practises in South Surrey 鈥� 鈥渄ramatically altered鈥� her life has had her negligence claim dismissed in B.C. Supreme Court.

In the claim, Maria De Sousa alleged Dr. John Rogers 鈥� of White Rock Dental Group 鈥� breached the standard of care when he extracted a lower molar during her first appointment with him in June 2011, 鈥渄espite not being able to find an issue with the tooth that would justify this most aggressive of treatment methods.鈥�

Dr. Michael Racich, she alleged, breached the standard of care when he 鈥渃hose to place three implants鈥� despite 鈥渒nowledge of the possibility of neuropathic pain.鈥� Those treatments occurred between December 2011 and January 2013.

However, in reasons for judgment posted last Friday (Feb. 1), Justice Stephen Kelleher found that evidence presented 鈥渄oes not establish鈥� that either of the dentists breached the standard of care, or that their actions caused the damages suffered.

In his reasons, Kelleher notes 鈥渁 history of treatment鈥� for De Sousa鈥檚 extracted tooth dating back to 2004 and involving at least 11 other dental professionals, as well as a neurosurgeon. Several of those professionals testified in the civil trial, which was heard last year over 13 days in June, July and November.

Kelleher made his ruling on Feb. 1.

According to the reasons for judgment, the court heard that De Sousa was a patient with one South Surrey dentist for just over two years starting in July 2004. In that time, De Sousa did not follow recommendations for regular visits, nor did she proceed with a recommended crown on the tooth in question, which was suggested following a 鈥渇ractured restoration鈥� on the tooth that De Sousa said was 鈥渢rapping food,鈥� the court heard.

Procedures performed or recommended by various dentists over the years following included root canals, crowns and specialist referrals. There were also suggestions the pain could be due to a neurological condition.

De Sousa testified that after Rogers removed her tooth, she was left with a sharp burning pain. While she denied insisting Rogers extract the tooth, she agreed that she had said, in her examination for discovery, that she 鈥渁sked鈥� for the extraction.

De Sousa also testified that implants were the only treatment Racich suggested, that all she was given to prepare for them was a tube of Colgate toothpaste, that she had a lot of pain after the procedures and that Racich told her it was neuropathic pain.

De Sousa鈥檚 husband and daughters testified that De Sousa often complained of 鈥渂urning pain鈥� on the right side of her mouth after the extraction. She stopped dancing and driving, and lost interest in gardening, among other things, the court heard.

A neurologist testified that De Sousa has persistant idiopathic facial pain; described in the court document as 鈥渁 disorder of unknown cause which can be exacerbated by dental procedures.鈥�

Those procedures, the neurologist testified, are commonly an effort to address the initial complaint, but are often futile as the disorder is 鈥渢ypically not of primary dental origin.鈥�

In his reasons, Kelleher said De Sousa鈥檚 recollection of the circumstances or her treatment and her interaction with the dentists who saw her 鈥渨as, to put it kindly, imperfect.鈥�

鈥淢s. De Sousa鈥檚 evidence must be considered in light of her relatively poor memory. Moreover, much of what she told the Court is inconsistent with the 鈥榩robabilities of the case as a whole,鈥欌�� the judgment states.

Kelleher dismissed the evidence of one expert called by the plaintiff, noting 鈥渄eeply flawed鈥� instructions from counsel that included asking the expert to provide an opinion 鈥渞egarding Maria De Sousa鈥檚 general disability arising from her medical malpractice injuries and the extent to which this interferes with her activities鈥︹��

The instructions 鈥渟uggest that (the expert) was instructed to assume that there has been negligence and medical malpractice,鈥� Kelleher found.

鈥淎s such, any conclusion reached by an expert based on these instructions is, as the defendants argue, a self-fulfilling prophecy.鈥�

Kelleher described the defendants鈥� evidence as 鈥渦nshaken in cross-examination.鈥�

Kelleher found that De Sousa has a history of self-diagnosis and of refusing treatment when she disagrees with the professional. While he said that is her right, 鈥渋t does not constitute tortious conduct on the part of the defendants.鈥�
