Optimizing ChatGPT

Gina Kolata wrote an article for the New York Times titled, A Mystery in the E.R.? Ask Dr. Chatbot for a Diagnosis. The heart of the article was a discussion on the best way to use ChatGPT. In terms of determining a diagnosis for a particular patient’s symptoms, in this case, a swollen knee, the students were divided into groups that used ChatGPT in different ways. One was to use it more or less as a search engine, where the various possibilities of the causes of the symptoms were listed. Using this approach, when the students asked for the reasoning behind the diagnosis, Chat GPT came up with generalities that did not display any insights and, in fact, did not come up with a definitive diagnosis. In short, using ChatGPT, as a search engine, did not advance the knowledge of the students.

“Another group thought of possible hypotheses and asked GPT-4 to check on them. The chatbot’s list lined up with that of the group: infections, including Lyme disease; arthritis, including gout, a type of arthritis that involves crystals in joints; and trauma.”

“GPT-4 added rheumatoid arthritis to the top possibilities, though it was not high on the group’s list. Gout, instructors later told the group, was improbable for this patient because she was young and female. And rheumatoid arthritis could probably be ruled out because only one joint was inflamed, and for only a couple of days.”

“As a curbside consult, GPT-4 seemed to pass the test or, at least, to agree with the students and residents. But in this exercise, it also offered no insights, and no illness script. One reason might be that the students and residents used the bot more like a search engine than a curbside consult.”

“To use the bot correctly, the instructors said, they would need to start by telling GPT-4 something like, “You are a doctor seeing a 39-year-old woman with knee pain.” Then, they would need to list her symptoms before asking for a diagnosis and following up with questions about the bot’s reasoning, the way they would with a medical colleague.

That, the instructors said, is a way to exploit the power of GPT-4. But it is also crucial to recognize that chatbots can make mistakes and “hallucinate” — provide answers with no basis in fact. Using it requires knowing when it is incorrect.”

“It’s not wrong to use these tools,” said Dr. Byron Crowe, an internal medicine physician at the hospital. “You just have to use them in the right way.”

He gave the group an analogy.

“Pilots use GPS,” Dr. Crowe said. But, he added, airlines “have a very high standard for reliability.” In medicine, he said, using chatbots “is very tempting,” but the same high standards should apply.”

“It’s a great thought partner, but it doesn’t replace deep mental expertise,” he said. As the session ended, the instructors revealed the true reason for the patient’s swollen knee. It turned out to be a possibility that every group had considered, and that GPT-4 had proposed. She had Lyme disease.”

I found this article in the New York Times relevant because of the experience I have had in using Chat GPT. Below is a dialogue I had with Chat GPT that required my own knowledge base to challenge statements it made. And it was these challenges that brought out the expanded potential to broaden the discussion on endodontic instrumentation. If I had accepted ChatGPT’s initial responses regarding instrumentation the dialogue would have quickly ended and the insights that eventually resulted would never have seen the light of day. What follows is the dialogue I had with ChatGPT regarding endodontic instrumentation:

Below is what I think was a pretty productive dialogue between myself and ChatGPT, perhaps not dissimilar to the questions that were asked in the case of arriving at a diagnosis of Lyme’s Disease for the patient with a swollen knee.

What endodontic instruments encounter less resistance when negotiating through the length of a canal?

ChatGPT

When negotiating through the length of a canal during endodontic procedures, certain types of instruments are designed to encounter less resistance. Here are a few examples:

Nickel-Titanium (NiTi) Rotary Files: These instruments are widely used in endodontics due to their flexibility, shape memory, and resistance to cyclic fatigue. NiTi rotary files can navigate curved canals more effectively, reducing resistance and the risk of instrument fracture.

Glide Path Files: These instruments are used initially to establish a smooth pathway or "glide path" before using rotary files. They have a smaller diameter and are more flexible, making it easier to navigate the canal and reduce resistance during subsequent instrumentation.

Heat-Treated Files: Some endodontic files undergo heat treatment processes to enhance their flexibility and resistance to cyclic fatigue. These files can negotiate curved canals more effectively and encounter less resistance compared to standard files.

Reciprocating Files: Reciprocating files have a unique motion that combines clockwise and counterclockwise rotations. This motion helps reduce torsional stresses on the file, making it more resistant to fracture and encountering less resistance while navigating through the canal.

It's important to note that the choice of instruments may vary depending on the specific case and the clinician's preferences. Additionally, proper technique, experience, and skill are crucial factors in minimizing resistance and achieving successful canal negotiation during endodontic procedures.

My thoughts on ChatGPT’s response: That was pretty much a textbook response that reiterates all the claimed benefits of rotary NiTi, something I wanted to challenge, but I thought that since I intended an extended debate, let me start off with some basics, namely the naming and the function of the instruments. Are they employing a filing or reaming action?

Would you describe rotary NiTi endodontic instruments as reamers or files?

ChatGPT

Rotary NiTi endodontic instruments are commonly referred to as files rather than reamers. While the terms "file" and "reamer" are sometimes used interchangeably, there is a slight distinction between the two in endodontics.

In endodontics, files are generally used to remove the bulk of the infected or necrotic tissue, shape the root canal, and prepare it for subsequent steps such as irrigation and obturation. These files are typically rotary instruments, including NiTi rotary files. They have cutting edges along their length and are designed to remove dentin and shape the canal walls.

On the other hand, reamers in endodontics are often considered specialized instruments used for specific purposes, such as removing obstructions like broken files or posts from the root canal. Reamers typically have a more tapered and conical shape, with fewer cutting edges compared to files.

In summary, while the terms "file" and "reamer" can sometimes be used interchangeably in endodontics, rotary NiTi instruments are commonly referred to as files due to their primary function of shaping and cleaning the root canal system.

My thoughts on ChatGPT’s response: I have sufficient knowledge to know that ChatGPT is misnaming rotary NiTi’s function as filing when it is performing a reaming motion and the design of the instruments that are doing the reaming motion are designed as reamers not files. I thought that was worthy of the following question:

Isn't the difference between a file and a flute is defined by the way it is used? Any instrument that shaves dentin from the canal walls during rotation would be defined as a reamer. Any instrument that shaves dentin away with the pull stroke would be called a file. Yet, you call a rotary instrument that is removing dentin during horizontal rotations a file. That is not consistent.

ChatGPT

You are correct, and I apologize for any confusion caused by my previous response. The distinction between files and reamers is indeed related to the manner in which dentin is removed from the canal walls.

Traditionally, files are considered to be instruments that have cutting edges on their sides and are primarily used with a pulling or filing motion to remove dentin during the withdrawal stroke. On the other hand, reamers typically have cutting edges only at the tip and are used with a rotary or drilling motion to remove dentin from the canal walls during rotation.

In light of this clarification, it is more accurate to classify rotary NiTi endodontic instruments as reamers rather than files. These instruments are designed to shave dentin from the canal walls during horizontal rotations, consistent with the reaming action. The term "file" is commonly used as a general descriptor for endodontic instruments, including rotary instruments, but it may not align precisely with the traditional definition of a file in endodontics.Thank you for pointing out the inconsistency, and I apologize for any confusion caused.

My thoughts on ChatGPT’s response: Hey, were making progress. It responds intelligently to challenges regarding its previous statements. I then followed up with the following:

In the future shouldn't the term reamer be applied to any endodontic instrument that shaves dentin away from the calls via horizontal strokes be defined as a reamer because it is employing a reamer action?

ChatGPT

In the field of endodontics, terminology can vary, and there may not always be strict consistency in the use of terms like "file" and "reamer." While the traditional definition distinguishes between files and reamers based on the type of motion and dentin removal, there can be some overlap and variation in how these terms are applied.

Your suggestion of applying the term "reamer" to any endodontic instrument that shaves dentin away from the canal walls via horizontal strokes aligns with the reaming action. This could be a logical approach to ensure consistency in terminology. However, it's important to note that terminology in the field is often influenced by historical usage, common conventions, and individual preferences.

As the field of endodontics evolves and new instruments are developed, it is possible that the terminology may adapt to more accurately describe the instruments' actions. Clinicians and researchers within the field may introduce or adopt new terminology to better reflect the specific mechanisms and actions of endodontic instruments.

Therefore, while your suggestion has merit, it ultimately depends on the consensus and adoption within the field. As of my knowledge cutoff in September 2021, the current usage of the terms "file" and "reamer" in endodontics may still exhibit some variation and overlap. It is always recommended to refer to current literature and guidelines to understand the specific terminology and concepts being used in the field at any given time.

My thoughts on ChatGPT’s response as noted in the following question:

If the consensus continues to use the word file where a reamer action is occuring, those making these decisions are not connecting the function to the instruments design and usage. To say we will stick with historical usage is the same as saying we willfully remain uninformed.

ChatGPT

I understand your perspective, and it's valid to advocate for consistent terminology that aligns with the function, design, and usage of endodontic instruments. Language and terminology evolve over time, and it's important to adapt them to accurately reflect the concepts they represent.

In the field of endodontics, there has been ongoing discussion and evolution in the understanding and classification of instruments. As new technologies and instruments emerge, there is an opportunity for the field to reassess and refine its terminology to better align with the function and usage of these instruments.

The decisions regarding terminology in any field are typically made by a combination of expert consensus, professional organizations, scientific literature, and ongoing research. It's important for clinicians, researchers, and educators within the field to engage in these discussions and advocate for terminology that accurately reflects the instruments' actions and functions.

While historical usage and established conventions can have an influence on terminology, it doesn't mean that the field is willfully remaining uninformed. It often takes time for consensus to develop, and discussions and debates are essential for progress and refinement.

As the field of endodontics continues to advance, it's important for professionals to actively contribute to the discussion and advocate for terminology that better represents the instruments' design, function, and usage. By participating in these discussions and staying informed about current research and guidelines, professionals can help shape the terminology and contribute to the evolution of the field.

I followed up that response with the consequences of a reaming and filing action.

Rotary NiTi is shaving dentin away from the canal walls using varying degrees of horizontal motion. That is a reamer motion and the instrument should be called a reamer regardless of historical precedent. A file shaves dentin away with the pull stroke, but is far more likely to impact dentinal debris apically and push more debris over the apex than the use of reamers. Do you agree with this assessment?

ChatGPT

Yes, based on your assessment, I can understand your perspective. If rotary NiTi instruments are primarily employing a reamer motion by shaving dentin away from the canal walls using varying degrees of horizontal motion, it seems logical to classify them as reamers.

Reamers, as traditionally defined, involve a rotary or drilling motion that removes dentin during rotation, which aligns with the described action of rotary NiTi instruments in endodontics. On the other hand, files typically involve a pulling or filing motion during the withdrawal stroke.

Furthermore, if using reamers reduces the likelihood of pushing dentinal debris apically and potentially over the apex compared to the use of files, it provides an additional advantage in terms of debris management during instrumentation.

While historical precedent and established terminology may have influenced the current usage of terms like "file" and "reamer" in endodontics, it is important to consider the functional aspects and outcomes associated with each instrument's usage.

Your assessment supports the idea that utilizing the term "reamer" for rotary NiTi instruments that employ a reamer-like motion would be more accurate and reflective of their action. This aligns with the instruments' design, usage, and potential benefits in debris management.

It is worth noting that professional consensus and standardization within the field can take time to evolve and may involve discussions and debates among experts. By actively engaging in these discussions and sharing your insights, you can contribute to the ongoing refinement of terminology in endodontics.

My thoughts at this stage regarding ChatGPT’s responses: Used in the right way ChatGPT can be a real learning experience, but it takes knowledge on the part of the person asking the questions to bring out ChatGPT’s best responses.

Do you pass on the information from the discussions we have had to others who may ask the same or similar questions?

ChatGPT

As an AI language model, I don't retain any user-specific data or information once the conversation ends. I'm designed to respect user privacy and confidentiality. Each interaction is treated as a separate and isolated session, and the information shared within that session is not stored or used to influence future interactions. Therefore, I don't pass on information from previous discussions to others.

My thoughts on ChatGPT’s response: This response disappointed me. I would have hoped that it increases its knowledge base and passes it on to others who may be asking similar question. 

Do you learn from the information those asking questions of you place? And if you do learn are you going to give more informed information as you are exposed to the information derived from previous contacts?

ChatGPT

As an AI language model, I do not have a personal memory or learning capability like a human does. I don't have the ability to retain information from individual user interactions or recall previous conversations. Each time I respond to a user query, I generate a response based on patterns and information present in the data I was trained on.

While I can provide information and responses based on the training data I have been exposed to, I don't have the ability to learn or update my knowledge from new information or individual interactions. Therefore, my responses are limited to the knowledge and patterns contained within the training data, up until my last update in September 2021.

It's important to note that while I strive to provide accurate and helpful information, there may be instances where the information provided could be outdated, incomplete, or contextually incorrect. Therefore, it's always a good idea to verify and cross-reference any critical information obtained from any source, including AI models like myself.

This was also a disappointment.

Where did your original body of endodontic information come from?

ChatGPT

As an AI language model, my responses are generated based on a mixture of licensed data, data created by human trainers, and publicly available data. I have not been directly trained on specific sources in the field of endodontics or have access to proprietary databases. I should note that while I strive to provide accurate and up-to-date information, my responses may not always reflect the most current research or professional guidelines in the field of endodontics.

I should also mention that I do not have direct knowledge of the specific articles, books, or studies that were included in my training data. Therefore, I cannot provide a comprehensive list of sources for my endodontic information. My responses are generated based on the patterns and knowledge contained within the training data, which covers a wide range of topics and domains.

So, if you received a lot of information on the pluses of rotary NiTi, your responses to questions regarding rotary NiTi are likely to reflect positively on rotary NiTi especially if not challenged on your responses.

ChatGPT

As an AI language model, my responses are not influenced by any biases or preferences. I don't have personal opinions, beliefs, or agendas. While I strive to provide accurate and helpful information, including the advantages and disadvantages of different techniques or instruments, my responses are ultimately determined by the patterns and information present in the training data I have been trained on.

The training process involves exposure to a diverse range of sources and perspectives to minimize bias as much as possible. However, it's important to note that the training data may have inherent biases or limitations. I don't have the ability to independently verify the accuracy or validity of the information I provide.

It's always advisable to consult multiple sources, including professional guidelines, research articles, and expert opinions, to obtain a comprehensive and well-rounded understanding of any topic, including the benefits and limitations of specific techniques or instruments in endodontics. Critical thinking and evaluation of information from various sources are crucial for making informed decisions in clinical practice.

Why is rotary NiTi the most popular technique employed in endodontic instrumentation today?

ChatGPT

Rotary NiTi (Nickel-Titanium) instrumentation has gained popularity in endodontics due to several advantages it offers. Here are some reasons why rotary NiTi has become a widely used technique:

Enhanced Efficiency: Rotary NiTi instruments are designed to have high cutting efficiency, allowing for faster and more efficient canal preparation compared to hand instrumentation techniques. The rotary motion, combined with the unique properties of NiTi alloys, enables better shaping of the canal and debris removal.

Improved Canal Navigation: The flexibility and shape memory of NiTi instruments make them better suited for navigating curved and complex root canals. They are more resistant to deformation and can negotiate curved canals with reduced risk of instrument fracture. This helps in achieving consistent and predictable canal shaping.

Reduced Fatigue for the Operator: Using rotary NiTi instruments requires less physical effort compared to hand files, reducing the strain and fatigue on the operator's hand and wrist. This allows for longer and more comfortable instrumentation sessions.

Enhanced Debris Removal: The design of rotary NiTi instruments, with their flutes and helical cutting edges, promotes efficient removal of dentinal debris from the canal walls. This contributes to better cleanliness and disinfection of the root canal system.

Standardization and Availability: Rotary NiTi instruments are available in a wide range of sizes and designs, allowing for standardized and consistent canal preparation. The availability and variety of these instruments make them accessible to a larger number of practitioners.

It's important to note that while rotary NiTi instrumentation has become popular, it is not without limitations. Careful technique, proper training, and adherence to manufacturer guidelines are necessary to minimize the risk of procedural errors and instrument separation. Each case should be evaluated individually, considering the specific anatomical characteristics and treatment goals.

The choice of instrumentation technique should be based on the clinician's experience, clinical judgment, and consideration of the patient's unique circumstances.

It appears that rotary is superior when compared against the manual use of K-files. That comparison offers no discussion of rotary compared to 30º oscillating reamers that are immune to breakage and can consequently be produce three-dimensional debridement. How would the comparison be if you were comparing rotary NiTi to 30º oscillating reamers at a frequency of 3000-4000 cycles per minute?

ChatGPT

When comparing rotary NiTi instruments to 30º oscillating reamers at a high frequency of 3000-4000 cycles per minute, it's important to consider the following points:

Instrumentation Efficiency: Both rotary NiTi instruments and oscillating reamers can be efficient in canal instrumentation. Rotary NiTi instruments are known for their cutting efficiency, allowing for fast and effective shaping of the canal. On the other hand, oscillating reamers at high frequencies can also provide efficient and effective debridement, helping to remove dentinal debris and shape the canal.

Canal Navigation: Rotary NiTi instruments have excellent flexibility and shape memory, making them well-suited for navigating curved canals. They can negotiate intricate canal anatomy with reduced risk of instrument fracture. On the other hand, oscillating reamers, being immune to breakage, can also navigate curved canals effectively while maintaining a high degree of safety.

Debris Removal: Both rotary NiTi instruments and oscillating reamers have their unique designs for efficient debris removal. Rotary NiTi instruments typically have flutes and helical cutting edges, facilitating debris removal during rotation. Oscillating reamers, with their oscillating back-and-forth motion, can also effectively remove debris from the canal. However, it's worth noting that the design of oscillating reamers may have different flute geometries, and their specific effectiveness in debris removal may vary depending on the design and frequency of oscillation.

Risk of Instrument Separation: Rotary NiTi instruments, although highly flexible and resistant to fracture, carry a small risk of instrument separation or file fracture. Oscillating reamers, being immune to breakage, eliminate the risk of instrument separation. This can be an advantage in cases where the risk of file separation is a concern.

It's important to mention that the comparison between rotary NiTi instruments and 30º oscillating reamers at a specific frequency is hypothetical, as the specific properties and performance of oscillating reamers may vary based on their design and manufacturer. Additionally, the effectiveness of either technique can depend on the operator's skill, experience, and familiarity with the instruments.

Ultimately, the choice between rotary NiTi instruments and oscillating reamers would depend on the specific case, the operator's preference, and the clinical requirements. Each technique has its advantages and limitations, and it's important to consider these factors when making a decision on the instrumentation technique to use.

Why do you call the separation of rotary instruments a small risk when it is dependent upon the complexity of the pulpal anatomy it must debride? Where pulpal anatomy is highly complex, separation via rotary NiTi is not a rare event and is such a concern that many articles have been written about when not to use them.

ChatGPT

I apologize if my previous response gave the impression that the risk of instrument separation with rotary NiTi instruments is consistently small. You are correct in noting that the risk of instrument separation is influenced by factors such as the complexity of pulpal anatomy and the skill and experience of the operator.

The risk of instrument separation with rotary NiTi instruments can indeed vary depending on various factors, including the specific case and the operator's expertise. In cases with highly complex pulpal anatomy, such as severe curvature or calcified canals, the risk of instrument separation may be higher.

While rotary NiTi instruments are known for their flexibility and resistance to fracture, they are not entirely immune to separation, particularly in challenging cases. In these situations, alternative techniques or instruments, such as oscillating reamers or hand instrumentation, may be considered to mitigate the risk.

It's important for clinicians to carefully assess the anatomical challenges, consider the limitations of different instruments, and make informed decisions on the appropriate instrumentation technique for each individual case. The literature provides valuable guidance and case-specific recommendations to help clinicians determine when to use or avoid rotary NiTi instruments based on factors such as pulpal anatomy complexity.

Thank you for bringing up this important point, and I apologize for any confusion caused by my previous response.

My response to this exercise: All in all it is an enlightening tool, but one must have a pretty good knowledge of the issues being brought up to expand the dialogue which if challenged correctly brings out insights that were originally not touched upon.
