In the first article of this series, I began to discuss treatment planning and the importance of knowing how research can and should impact our treatment recommendations and decisions with our patients.
Even with all of the recent advancement in technology, new materials and techniques, periodontal disease still affects nearly 50 percent of the American population over the age of 30 according a study done.(1) As the periodontal disease progresses and bone loss gets worse, the posterior teeth eventually have enough bone loss to impact and involve the furcation areas. Eventually, the teeth become what has been described as questionable or hopeless. In the years prior to dental implants the typical treatment plan for dental professionals tried to maintain and keep teeth as long as possible, even in situations that were less-than-ideal.
Treatment Plan: To Extract or Not to Extract?
Even when they were less-than-ideal, dentists tried to figure out a way to buy a few more years for those patients and their hopeless teeth. Nowadays, with implants being a more predictable restoration in some situations, we will present a treatment plan that involves removing the questionable tooth and replacing it with a more predictable solution, the dental implant, to our patients. So, the question is: when do we do this and how do we know?
Well, for years, when it came to questionable or hopeless furcation involved teeth, the discussions I had with patients often was about the loss of the tooth and replacement options. This was usually limited since the periodontal disease not only impacted the current tooth â but the adjacent teeth and the potential future implant site. Well, after having this discussion more than a few times, I finally decided to set my own convictions aside, do the research and look at the numbers I referred to in my last article; the research that helps me and my patients make better decisions.
In a recently published article in the Journal of Periodontology,(2) a university-based study that monitored 102 patients and over 800 molars, and had post-treatment ranged from 15 to 40 years, with an average of 24 years. They scored each patient based on smoking, age, probing depths, mobility, furcation involvement, and molar type (1st vs. 2nd vs. maxillary vs. mandibular). So, what did they find? Well, the results really opened my eyes and have given me something to share with my patientsâ¦
- 78 percent of the molars survived and of those, 89 percent were classified as healthy status;
- Lower scores (one to three) at 15 years had 96 to 99 percent survival rate;
- Scores of (four to six) at 15 years had 90 to 95 percent survival rate;
- Higher scores at 15 years had 67 to 86 percent survival rate.
They found, as other studies did, smoking impacted the overall survival rate the most, followed by probing depths and mobility. As you can see, diligent periodontal care, as well as surgical intervention, can allow patients to keep and maintain their own dentition for years versus simply removing the questionable or hopeless tooth/teeth.
This long-term study can give you and your patient an evidence-based way to assess their risk and benefits of keeping versus removing teeth, thus allowing you both the opportunity to make the best decisions on treatment planning now and for the future.
