This best-selling review guide consolidates the plethora of study materials and scattered information available into a single comprehensive source designed to prepare students for periodontal examinations as well as clinical practice. The material is presented in a clear question and answer format, with references to both classic and more recent literature on topics such as diagnosis, nonsurgical therapy, surgical therapy, regeneration, and implants, and answers are supplemented with relevant tables, illustrations, and pictures throughout. This revised second edition includes new figures, tables, and treatment planning cases, as well as a comprehensive review of the new classifications of periodontal and peri-implant diseases and conditions, providing the most up to date information for those seeking board certification.

Evidence-based dentistry is the merging of clinically pertinent scientific evidence to the patientās oral and medical condition and history as well as the dentistās experience (Fig 1-1). The dentist uses the evidence to make sound decisions about diagnosis, prognosis, and treatment. Evidence-based decision making consists of formulating patient-centered questions (Population-Intervention-Comparison-Outcome [PICO]); examining and critically evaluating the evidence; and relating the evidence to practice.1
Q: What is the PICO question?
The PICO question is a question that includes a population to be examined, the nature of the intervention to be inspected, a comparison statement, and the type of outcome to be evaluated. It should be problem-focused and concise.
Example: In patients with horizontal alveolar ridge deficiencies (population), what is the effect of horizontal bone augmentation procedures (intervention) compared with controls (comparison) on peri-implant health (outcome)?
Q: What is the step-by-step process for making an evidence-based decision in a dental practice?
The steps involved in evidence-based decision making in a dental practice are shown in Fig 1-2.
Studies
Q: What are the different study types (ranked from highest level of evidence to lowest)?
The different types of studies are shown, ranked in order of highest to lowest level of evidence, in Fig 1-3.
Q: Describe the difference between a cross-sectional study and a longitudinal study.
A cross-sectional study is done at one time point, whereas a longitudinal study ranges over a period, allowing temporal relationships to be investigated.
Q: What is the P value?
The P value is the probability of obtaining a test statistic at least as extreme as the one observed, assuming that the null hypothesis is true. The smaller the P value, the less likely the effect was due to chance. A P value less than or equal to .05 usually indicates statistical significance.
Q: What is the difference between sensitivity and specificity?
Sensitivity is the ability of a test to correctly identify diseased individuals. Specificity is the ability of a test to correctly identify a healthy individual.
For instance, the diagnostic sensitivity of a clinical parameter (suppuration, gingival plaque) in predicting disease was expressed as the proportion of sites showing attachment loss that also exhibited the given parameter. Diagnostic specificity was expressed as the proportion of sites not exhibiting the clinical parameter and not showing attachment loss.4
Q: What is the difference between internal and external validity?
The difference between internal and external validity is shown in Fig 1-4.
Q: Why practice evidence-based dentistry?5
1. There are thousands of articles published monthly in dental magazines. It would take hundreds of hours to read the dental literature. Using evidence-based review databases eases the necessary time spent evaluating dental literature.
2. Practicing evidence-based dentistry keeps dentists current on recent evidence and practice standards.
3. A thorough and analytical literature review should be carried out before proceeding in clinical research.
