At Norfolk Dental Specialists, we like to stay abreast of the latest developments in our particular dental specialisms of periodontal disease, endodontics and implantology. We also like to share our knowledge of any developments in these fields with our referring GDPs and patients. In this week’s blog post, the latest in our series of clinical study abstracts, we’ll be looking at a study led by Niklaus P Lang. The eminent periodontist and his team examined the academic dental literature to identify and compare different computerised tools that have been used to assess the risk of periodontitis progression.
The Questions
This meta-analysis attempted to answer two questions:
The Meta-Study Approach
Conducting a meta-analysis involves setting inclusion criteria and then conducting a thorough review of all the relevant scientific literature to find studies that meet these criteria. To avoid bias, it is essential that the criteria are set before the search is conducted. Once all the acceptable studies have been found, their combined results can be analysed. In this instance, conducting a meta-study allowed different tools that have been developed for the measurement of risk in periodontitis progression to be compared.
Characteristics of Five Different Tools
Computerised and manual screening of swathes of dental literature revealed 19 studies that fitted the inclusion criteria. Five different tools for assessing patient-based periodontal risk were identified. Each of them had been analysed in at least one study, but never had the five been compared to one another for efficacy in predicting periodontitis progression. Which would be the best?
Each of these analysis tools aims to achieve the same result – prediction of periodontitis progression in adults. Each tool has been studied individually. The studies contain patient data that records the prediction being made and how accurate the prediction proved to be. By combining the studies, the authors of the meta-study hoped to prove which tool worked best.
Results
With the caveat that additional research was needed, the authors concluded that the PRC and PRA models were the most effective at predicting tooth loss. However, Dr Debra M Ferraiolo has questioned the legitimacy of these results. In a commentary for the journal Evidence Based Dentistry, she concluded:
“Despite the authors’ claim that PRC and PRA are the best tools, the evidence does not necessarily indicate which of the tools is ‘best’. Also, there is the potential for a conflict of interests since two of the authors developed the PRA tool.”
Our Approach
At Norfolk Dental Specialists, we pride ourselves on our patient-centred approach. Each of these computer algorithms is a handy tool to call on if necessary, but they can never be a substitute for knowing and understanding patients and their motivations.
