You don&#8217;t need to wait until you have reviewed every concept. At this stage, the goal is to identify where your preparation time will have the greatest effect.<\/p>\n<p>Review your results by section and content area:<\/p>\n<ul>\n<li style=\"margin-bottom: 10px\"><strong style=\"font-weight: 600\">Scientific Basis for Dental Hygiene Practice:<\/strong> Do you need more work with anatomy, physiology, biochemistry, nutrition, microbiology, immunology, pathology, pharmacology, or local anesthesia?<\/li>\n<li style=\"margin-bottom: 10px\"><strong style=\"font-weight: 600\">Provision of Clinical Dental Hygiene Services:<\/strong> Can you assess patients, interpret radiographs, plan care, manage periodontal disease, select preventive agents, provide supportive services, and apply professional responsibilities appropriately?<\/li>\n<li><strong style=\"font-weight: 600\">Research Principles and Community Health:<\/strong> Can you interpret scientific literature and statistics, apply research findings, assess community needs, and design or evaluate oral-health programs?<\/li>\n<\/ul>\n<p>Identifying those specific weaknesses will show you where to devote more attention during your study time.<\/p>\n<h3><span id=\"Review_Difficult_Questions\" class=\"m-toc-anchor\"><\/span>Review Difficult Questions<\/h3>\n<p>After each practice session, review every question you answered incorrectly AND every question you guessed on or answered with low confidence. Guessing correctly does not necessarily mean that you have mastered the skill.<\/p>\n<p>For each difficult question, determine which of the following caused the problem:<\/p>\n<ul>\n<li>You didn&#8217;t know the underlying biomedical or dental hygiene concept.<\/li>\n<li>You knew the concept but could not apply it to the patient.<\/li>\n<li>You overlooked an important medical-history finding.<\/li>\n<li>You failed to consider a medication, allergy, vital sign, or systemic condition.<\/li>\n<li>You misinterpreted a radiograph, clinical photograph, or dental chart.<\/li>\n<li>You overlooked an infection-control or emergency-management consideration.<\/li>\n<li>You made a statistical or research-interpretation error.<\/li>\n<li>You answered from memory without using information provided in the patient case.<\/li>\n<li>You changed a sound answer without identifying evidence that it was wrong.<\/li>\n<\/ul>\n<p>Then, outline a specific plan for improvement based on what you discovered. In other words, don&#8217;t just say, \u201cI need to study pharmacology.\u201d Specify that you need to review anticoagulants and determine which findings, lab values, and treatment considerations matter during dental hygiene care.<\/p>\n<p>Similarly, instead of saying &#8220;study periodontics,&#8221; create a precise goal like &#8220;practice interpreting probing depths&#8221; or &#8220;review nonsurgical periodontal therapy.&#8221;<\/p>\n<h3><span id=\"Utilize_Answer_Explanations\" class=\"m-toc-anchor\"><\/span>Utilize Answer Explanations<\/h3>\n<p>Answer explanations are an underutilized studying resource. To take full advantage of them, read the explanation for every question you found difficult, including questions you answered correctly.<\/p>\n<p>For each one, make sure you can confidently explain:<\/p>\n<ol>\n<li>Why the correct answer is correct<\/li>\n<li>Why each incorrect option is wrong<\/li>\n<li>What biomedical or dental hygiene principle is being tested<\/li>\n<li>Which patient information is relevant to the decision<\/li>\n<li>Whether the finding changes assessment, treatment, patient education, or follow-up care<\/li>\n<li>How the same concept could appear in a different NBDHE question<\/li>\n<\/ol>\n<p>For patient-assessment questions, identify exactly which part of the history or examination changes the decision. Does the medical history require treatment modification? Is the vital sign within an acceptable range? Is consultation or referral indicated?<\/p>\n<p>For radiography questions, return to the image and identify the evidence supporting your answer. Don&#8217;t just memorize what one radiograph supposedly showed. Practice locating anatomical landmarks, identifying abnormalities, evaluating bone levels, and integrating radiographic findings with the rest of the patient record.<\/p>\n<h3><span id=\"Study_Clinical_Decisions,_Not_Individual_Questions\" class=\"m-toc-anchor\"><\/span>Study Clinical Decisions, Not Individual Questions<\/h3>\n<p>Memorizing the answer to one NBDHE question won&#8217;t prepare you for another question that tests the same concept using a different medical history, periodontal condition, medication list, radiograph, or treatment need.<\/p>\n<p>Your goal should be to understand how dental hygiene knowledge changes what you assess, plan, perform, recommend, or report.<\/p>\n<p>The exact questions on your test will be different from the ones you encounter during practice. If you can explain a skill without looking at your notes and then apply it correctly to a new question, that is a good indication that you have mastered it.<\/p>\n<h2 class=\"pt-page\"><span id=\"FAQs\" class=\"m-toc-anchor\"><\/span>FAQs<\/h2>\n<div class=\"faq-list\">\n<div class=\"qa_wrap\">\n<div class=\"q_item text_bold\">\n<h4 class=\"letter\">Q<\/h4>\n<p style=\"line-height: unset;\">How many questions are on the NBDHE exam?<\/p>\n<\/p><\/div>\n<div class=\"a_item\">\n<h4 class=\"letter text_bold\">A<\/h4>\n<p>There are 350 multiple-choice questions on the exam.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"qa_wrap\">\n<div class=\"q_item text_bold\">\n<h4 class=\"letter\">Q<\/h4>\n<p style=\"line-height: unset;\">How long is the NBDHE exam?<\/p>\n<\/p><\/div>\n<div class=\"a_item\">\n<h4 class=\"letter text_bold\">A<\/h4>\n<p>The time limit for the exam is 7.5 hours.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"qa_wrap\">\n<div class=\"q_item text_bold\">\n<h4 class=\"letter\">Q<\/h4>\n<p style=\"line-height: unset;\">What is the passing score for the NBDHE exam?<\/p>\n<\/p><\/div>\n<div class=\"a_item\">\n<h4 class=\"letter text_bold\">A<\/h4>\n<p>To pass the exam, you must achieve a scaled score of at least 75.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"qa_wrap\">\n<div class=\"q_item text_bold\">\n<h4 class=\"letter\">Q<\/h4>\n<p style=\"line-height: unset;\">How much does the NBDHE exam cost?<\/p>\n<\/p><\/div>\n<div class=\"a_item\">\n<h4 class=\"letter text_bold\">A<\/h4>\n<p>The examination fee is $600.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n\n<p><div itemscope=\"\" itemprop=\"author\" itemtype=\"http:\/\/schema.org\/Person\" class=\"author-bio\"><img loading=\"lazy\" decoding=\"async\" itemprop=\"image\" class=\"author-image\" height=\"127\" width=\"127\" alt=\"Headshot of Mometrix associate Peter Rench.\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2024\/01\/Peter-Rench-scaled.webp\"><div class=\"author-text\"><p class=\"author-name\">By <span itemprop=\"name\">Peter Rench<\/span><\/p><div class=\"author-desc\"><p>Peter Rench joined Mometrix in 2009 and serves as Vice President of Product Development, responsible for overseeing all new product development and quality improvements.
