OPINION
These are consolidated appeals, in which Appellant Eric Fine (“Fine”) sued Appellee Mary Anne Checcio, D.D.S. (“Dr. Checcio”), and Appellee Rosezetta Marie Ward (“Ward”) sued Appellants Jeffrey W. Rice, D.M.D. and Jeffrey W. Rice, *260 D.M.D., P.C. (collectively, “Dr.Rice”), for dental malpractice. Dr. Checcio and Dr. Rice each filed a motion for summary judgment based on the two year statute of limitations in 42 Pa.C.S. § 5524(2). 1 In their respective responses, Fine and Ward raised the discovery rule and the doctrine of fraudulent concealment. At the trial court level, Dr. Checcio’s motion for summary judgment was denied, but Dr. Rice’s motion for summary judgment was granted. The Superior Court reversed the trial court in both cases. We conclude that neither Dr. Checcio nor Dr. Rice was entitled to summary judgment. Accordingly, for the reasons that follow, we reverse the Superior Court’s order in the appeal brought by Fine and affirm the Superior Court’s order in the appeal brought by Dr. Rice.
The record on summary judgment in each of these cases may be summarized as follows:
Fine v. Dr. Checcio
In June of 1998, Dr. Checcio recommended that Fine’s four wisdom teeth, three of which were impacted and one malaposed, be surgically extracted. Fine accepted Dr. Checcio’s recommendation and signed a consent form, which set forth the complications and physical conditions that could follow the surgery. The consent form included: “Lip, tongue, chin, gums, cheeks, and teeth, Parasthesia/Anesthesia (Numbness may be permanent)”. (R.198a). Dr. Checcio and Fine discussed the procedure and what Fine could expect. While Dr. Checcio testified in her deposition that she explained to Fine that the risk in his case. for post-operative numbness was higher than usual because of the position of the inferior alveolar nerve in his mouth, Fine testified in his deposition that Dr. Checcio did not do so.
*261 Dr. Checcio removed Fine’s four wisdom teeth on July 17, 1998, cutting soft tissue and drilling bone. At that point, Fine had pain, bleeding, infection, swelling, and numbness on both sides of his face. As of July 17, 1998, Fine knew he was “hurt”; considered the conditions he was experiencing to be “normal”; believed the facial numbness to be one of several “after-surgery effects”; and found the numbness “significant” in scope. (R. 175a, 343a, 347a). Except for the numbness, these conditions disappeared entirely. From July 20, 1998 to October 9, 1998, Fine saw Dr. Checcio in her office on ten separate occasions. During each of the visits, Fine and Checcio discussed the lack of sensation that Fine continued to experience in his face. According to Fine, Dr. Checcio repeatedly told him that it would take about six months for the numbness to subside. According to Dr. Checcio, she consistently gave Fine a balanced prognosis, informing’ him that in the worst case scenario, she would refer him to an oral maxillofacial surgeon for an evaluation. While sensation returned to most of Fine’s face, the numbness in an area approximately two fingers in width and an inch in length on the left side of his lip and chin persisted. On April 16, 1999, Fine signed an authorization that permitted his attorney to retrieve his medical records from the surgery. About a year after the surgery was performed, Fine came to believe that the persistent numbness was abnormal.
On August 8, 2000, Fine commenced an action in tort against Dr. Checcio. In his amended complaint, Fine alleged, inter alia, that Dr. Checcio was negligent in transecting his inferior alveolar nerve during the surgery and for failing thereafter to refer him to a neurosurgeon. Fine also alleged that the damage to the nerve caused him permanent facial numbness. Dr. Checcio raised the statute of limitations as an affirmative defense in her answer and new matter.
On November 5, 2001, Dr. Checcio filed a motion for summary judgment, asserting that Fine’s action, filed on August 8, 2000, was time-barred under 42 Pa.C.S. § 5524(2), inasmuch as it was not filed within two years of July 17, 1998, the date of Fine’s surgery. In response, Fine asserted that there *262 existed material, disputed facts as to whether the limitations period was tolled under the discovery rule or the doctrine of fraudulent concealment. The trial court denied Dr. Checcio’s motion for summary judgment, without opinion. The case proceeded to trial. On April 26, 2002, a jury returned a $500,000 verdict in Fine’s favor. Dr. Checcio’s post-trial motions were denied. A judgment was entered in Fine’s favor on August 28, 2002. Dr. Checcio filed a timely appeal in the Superior Court.
On appeal, Dr. Checcio asserted, inter alia, that the trial court erred in denying her motion for summary judgment. In an unpublished opinion, the Superior Court agreed and reversed the judgment for Fine. 2 The Superior Court found that on July 17, 1998, when the surgery ended, Fine knew that he was hurt and that he was experiencing significant and unexpected numbness. Based on these facts, the Superior Court concluded that the discovery rule was inapplicable because Fine knew of his injury and its cause at the time the injury was inflicted. Determining that Fine failed to establish that Dr. Checcio either intentionally or unintentionally concealed the true nature of his injury from him, the Superior Court also concluded that the doctrine of fraudulent concealment was not triggered. Thus, the Superior Court ruled that the limitations period in 42 Pa.C.S. § 5524(2) began to run on July 17, 1998, and held that Fine’s action, having been commenced more than two years from that date, was time-barred.
Fine filed a petition for allowance of appeal, which this court granted.
Ward v. Dr. Rice
On February 8, 1995, Dr. Rice recommended to Ward that her four impacted wisdom teeth be surgically removed and explained the surgical procedure he would perform. In Dr. Rice’s experience, temporary paresthesias and anesthesias commonly followed the procedure. It was Dr. Rice’s customary practice to inform patients like Ward that paresthesia and *263 numbness to the lip were complications of wisdom tooth extraction. In his deposition, Dr. Rice testified that because Ward was older, he told her that the risk of numbness increases with age. Ward testified in her deposition that no such conversation with Dr. Rice took place. Dr. Rice’s assistant provided Ward with a consent form, which she signed. In the consent form, Ward acknowledged that Dr. Rice had explained the nature, purpose, and results of the operation to her.
Dr. Rice surgically extracted Ward’s four wisdom teeth on March 28, 1995, cutting tissue and drilling bone. Immediately following the surgery, Ward’s face was sore and numb. When the hospital where the surgery was performed telephoned Ward the next day to inquire about her condition, Ward indicated that she was fine and did not mention the soreness or numbness. The numbness on the left side of Ward’s face continued. Ward had numerous post-operative office visits with Dr. Rice, starting on April 5, 1995, and ending on January 22, 1996. During the visits, Ward and Rice discussed her facial numbness. Ward testified that Dr. Rice repeatedly told her that sensation would return in two months’ time. Dr. Rice testified that he advised Ward that numbness is a complication of the operation he performed; that statistics show that feeling could return in about two months; and that because no one can know what the future holds, there was hope and a chance of recovery. At Ward’s seventh office visit with Dr. Rice on September 20, 1995, Dr. Rice referred her to Steven Kaltman, D.M.D. On October 11, 1995, Ward consulted with Dr. Kaltman, who outlined options for treating the numbness and pain. Ward returned to Dr. Rice for one last office visit on January 22, 1996. In March of 1997, Dr. Rice referred Ward to another oral surgeon for a consultation. At that point, Ward decided to sue Dr. Rice.
On September 26, 1997, Ward commenced an action in tort against Dr. Rice. Ward alleged that Dr. Rice committed a battery in performing the surgery without her informed consent, and was negligent in severing her inferior alveolar nerve and for failing to refer her to a neurosurgeon for repair. *264 Ward also alleged that Dr. Rice’s battery and negligence caused her nerve damage, severe pain, numbness, and discomfort. Dr. Rice raised the statute of limitations as an affirmative defense in his answer and new matter.
On February 15, 2002, Dr. Rice filed a motion for summary judgment, asserting that the limitations period in 42 Pa.C.S. § 5524(2) expired on March 29, 1997, which was two years after the surgery, and that Ward’s action, commenced on September 26, 1997, was barred under the statute. Ward responded that her action was timely insofar as the record showed that the statute of limitations was tolled under the discovery rule and the doctrine of fraudulent concealment.
On June 18, 2002, the trial court granted Dr. Rice’s motion and ordered summary judgment in Dr. Rice’s favor. The trial court determined that the discovery rule did not toll the statute of limitations on Ward’s claims because Ward knew of her injury and its cause immediately following the surgery and knew that her condition was not improving. The trial court also determined that Ward did not sustain her burden of showing that Dr. Rice concealed Ward’s condition from her inasmuch as she experienced pain and numbness as soon as the surgery was completed. Ward filed a timely appeal.
In a published opinion, the Superior Court reversed the judgment entered for Dr. Rice and remanded to the trial court for further proceedings.
Ward v. Rice,
Dr. Rice filed a petition for allowance of appeal, which this court granted. Because Dr. Rice’s and Fine’s respective requests for review covered the same issues; namely, whether the Superior Court erred in its determinations regarding the discovery rule and the doctrine of fraudulent concealment in connection with a motion for summary judgment that is based on the statute of limitations, we consolidated these appeals.
The Pennsylvania Rules of Civil Procedure that govern summary judgment instruct in relevant part, that the court shall enter judgment whenever there is no genuine issue of any material fact as to a necessary element of the cause of action or defense that could be established by additional discovery. Pa.R.C.P.1035.2(l). Under the Rules, a motion for summary judgment is based on an evidentiary record that entitles the moving party to a judgment as a matter of law. Note to Pa.R.C.P.1035.2.

In considering the merits of a motion for summary judgment, a court views the record in the light most favorable to the non-moving party, and all doubts as to the existence of a genuine issue of material fact must be resolved against the moving party.
Jones v. SEPTA,
*266
Our analysis begins with the principles in this area of the law that are settled. The Judicial Code provides in pertinent part that limitations periods are computed from the time the cause of action accrued. 42 Pa.C.S. § 5502(a). In Pennsylvania, a cause of action accrues when the plaintiff could have first maintained the action to a successful conclusion.
Kapil v. Association of Pa. State College and Univ. Faculties,
There are exceptions that act to toll the running of a statute of limitations. The discovery rule and the doctrine of fraudulent concealment are such exceptions. As both are implicated in this appeal, we will discuss them seriatim.
The discovery rule originated in cases in which the injury or its cause was neither known nor reasonably knowable.
See Lewey v. H.C. Frick Coke Co.,
As the discovery rule has developed, the salient point giving rise to its application is the inability of the injured, despite the exercise of reasonable diligence, to know that he is injured and by what cause.
Pocono International,
Therefore, when a court is presented with the assertion of the discovery rules application, it must address the ability of the damaged party, exercising reasonable diligence, to ascertain that he has been injured and by what cause.
Id.
*268
Since this question involves a factual determination as to whether a party was able, in the exercise of reasonable diligence, to know of his injury and its cause, ordinarily, a jury is to decide it.
Hayward,
When the discovery rule applies, the statute of limitations does not commence to run at the instant that the right to institute suit arises, i.e., when the injury occurs.
Id.
at 611;
Ayers,
While these broad parameters of the discovery rales operation are established, there is an aspect of the rule that has remained unsettled. Based on language in one of our cases,
Schaffer v. Larzelere,
Relying on this language in subsequent cases, some Justices have indicated that the discovery rule requires that it first be determined whether the injury and its cause were reasonably ascertainable at any point within the prescribed statutory period. If they were, then the discovery rule does not apply and the statute of limitations is not tolled, even though a party did not know nor could have reasonably known of his injury and its cause at the time the injury occurred.
See Saavedra,
Today, we hold that it is not relevant to the discovery rules application whether or not the prescribed period has expired; the discovery rule applies to toll the statute of limitations in any case where a party neither knows nor reasonably should have known of his injury and its cause at the time his right to institute suit arises.
We have several reasons for our holding. First, the observation made in
Schaffer,
to the extent that it was intended to limit the discovery rules application, constitutes non-binding dicta inasmuch as our holding therein concerned whether the plaintiff was permitted to amend a pleading to assert that defendant had concealed the facts underlying his negligent conduct.
Schaffer,
In addition to the discovery rule, the doctrine of fraudulent concealment serves to toll the running of the statute of limitations. The doctrine is based on a theory of
*271
estoppel, and provides that the defendant may not invoke, the statute of limitations, if through fraud or concealment, he causes the plaintiff to relax his vigilance or deviate from his right of inquiry into the facts.
Deemer,
As of yet, we have not directly considered and ruled upon the circumstances under which a defendant, once estopped under the doctrine of fraudulent concealment, may invoke the statute of limitations and commence its running. Inasmuch as the doctrine is premised on a defendant’s obstructionist conduct, there is an argument that a plaintiffs actual knowledge, of his injury and its cause, as opposed to the knowledge that reasonable diligence would give him, should control.
See e.g., Urland v. Memll-Dow Pharmaceuticals, Inc.,
We are of the view, however, that the standard of reasonable diligence, which is applied to the running of the statute of limitations when tolled under the discovery rule, also should apply when tolling takes place under the doctrine of fraudulent concealment. This is, we believe, the standard that will serve one of the overarching tenets in this area of our jurisprudence—the responsibility of a party who seeks to assert a cause of action against another to be reasonably diligent in informing himself of the facts upon which his recovery may be based.
Pocono International,
We now apply these exceptions to the running of the statute of limitations in each of the cases before us. We begin with Fine’s appeal. With respect to the discovery rule’s application, we must address what the record reveals as to Fine’s ability, exercising reasonable diligence, to know of his injury and its cause.
See Pocono International,
Viewing the summary judgment record as we must, in the light most favorable to the non-moving party, see supra, p. 8, we agree with Fine. It is important to keep in mind that in this case, the record revealed that facial numbness was indicative of two distinct phenomena. Facial numbness was either a temporary physical consequence that resulted from the very nature of the procedure that Dr. Checcio performed on Fine or it was a manifestation of Fine’s injury, a permanent condition that resulted from underlying nerve damage. Until conflicts in the record were resolved, see supra, pp. 2-3, and inferences from relevant facts were drawn, the issue of whether Fine knew, or should have known through the diligence that a reasonable person would have exercised *273 under the circumstances, that the numbness he was experiencing on July 17, 1998, was a manifestation of injury, as, opposed to, or in addition to, the typical condition that dental surgery produces remained disputed. Therefore, to rule against the discovery rule’s application, the Superior Court had to undertake these fact-resolution and inference-drawing functions. In doing so, the court erred. We emphasize that it is not the court’s function upon summary judgment to decide issues of fact, but only to decide whether there is an issue of fact to be tried. See Pa.R.C.P. 1035.2(1).
Turning to the doctrine of fraudulent concealment, while Fine argues that the issue had to be resolved at trial, Dr. Checcio argues that Fine failed to show that he could sustain his burden of proof on the doctrine’s application. Here too, we agree with Fine. We conclude that the Superior Court’s determination that Fine failed to establish that the statute of limitations was tolled by the doctrine disregarded the court’s proper role when presented with a motion for summary judgment and was erroneous. Fine based his assertion for the application of the doctrine on post-surgery statements he attributed to Dr. Checcio. As is reflected in their respective depositions, however, the parties disputed what Dr. Checcio actually said.
See supra,
p. 3. As we have instructed, it is for the jury to determine what remarks a defendant made to a plaintiff, before a court can decide whether they amounted to fraudulent concealment.
See Nesbitt,
Therefore, we hold that Dr. Checcio was not entitled to summary judgment because there were genuine issues of material fact necessary to her statute of limitations defense. See Pa.R.C.P. 1035.2(1). 5
*274 We now turn to Dr. Rice’s appeal. With respect to the discovery rule, the arguments made by Ward and Dr. Rice reflect those made by the parties in Fine’s appeal. Dr. Rice argues against the discovery rule’s application, contending that since Ward knew immediately after the surgery on March 28, 1995, that she was numb, she also knew at the same time that she had suffered an injury. Ward responds that given the nature of the procedure that she underwent and what she understood the procedure to involve, the record does not establish that she knew or reasonably could have known on March 28, 1998 that her numbness was indicative of an injury, and not a temporary post-operative condition.
Ward is correct. For the same reasons we stated in Fine’s appeal, the facts and inferences that are relevant to the discovery rule’s application—whether Ward knew or could have reasonably known that the numbness she admitted to experiencing upon the surgery’s completion was a manifestation of an injury, as opposed to, or in addition to, the typical and temporary conditions that dental surgery produces—are disputed and must be resolved at trial.
See supra,
p. 5. Therefore, as the Superior Court determined, Dr. Rice’s motion for summary judgment should have been denied.
See
Pa.R.C.P. 1035;
Hayward,
At this point, however, we observe that although we affirm the Superior Court’s result, we do not embrace the court’s analysis. The court focused on whether a jury could find Ward’s failure to investigate the causes of her condition until some seven months after the surgery to be reasonable.
See Ward,
Likewise, with regard to the doctrine of fraudulent concealment, while we agree that the Superior Court correctly determined that the doctrine precluded the entry of summary judgment for Dr. Rice, we disagree with the court’s approach. The court was in no position to base its ruling on the conclusion that Dr. Rice’s post-surgery statements were “assurances” of “full recuperation” that amounted to concealment.
Ward,
Therefore, we hold that Dr. Rice was not entitled to summary judgment because there are genuine issues of material fact as to his statute of limitations defense. See Pa.R.C.P. 1035.2(1). 7
*276 For these reasons, in Fine’s appeal, we reverse the order of the Superior Court reversing the order of the trial court denying Dr. Checcio’s motion for summary judgment; we reinstate the order of the trial court; and we remand the case to the Superior Court for the resolution of any properly preserved outstanding issues. For these reasons, in Dr. Rice’s appeal, we affirm the order of the Superior Court and remand the case to the trial court for further proceedings.
Madame Justice Newman did not participate in the consideration or decision of this case.
Notes
. It is undisputed in both appeals that 42 Pa.C.S. § 5524(2) controls. The statute states:
§ 5524. Two year limitation
The following actions and proceedings must be commenced within two years:
* * *
(2) An action to recover damages for injuries to the person or for the death of an individual caused by the wrongful act or neglect or unlawful violence or negligence of another.
42 Pa.C.S. § 5524(2).
. Dr. Checcio raised two other issues on appeal. Given its decision in regard to Dr. Checcio's motion for summary judgment, the Superior Court did not reach these additional issues.
, An appellate court may reverse the granting of a motion for summary judgment if there has been an error of law or an abuse of discretion.
Atcovitz v. Gulph Mills Tennis Club, Inc.,
. The language in
Schaffer
underlying this court’s division as to the discovery rule's application has been repeated in many opinions in boilerplate fashion.
See, e.g., Hayward,
. Given our conclusion, we need not and do not address Fine's additional argument that the Superior Court erred in ignoring his argument concerning the effect of his claim that Dr. Checcio failed to make a *274 timely referral to a neurosurgeon on the running of the statute of limitations.
. Because we conclude that application of the doctrine of fraudulent concealment to toll the statute of limitations is an open question to be resolved at trial, we need not. and do not address the Superior Court's determination that the tolled statute of limitations began to run in October 1995 when Ward consulted with another oral surgeon. See id. at 1125 n. 2.
. Given our conclusion, we need not. and do not address Dr. Rice’s argument that Ward is prohibited from avoiding the statute of limitations by asserting a negligent failure to refer claim.
