Theregisteredcompanyaddressis:Gewerbestrasse11,6330Cham,Switzerland Preface MachineLearninginDentistry Machine learning (ML) is a branch of artificial intelligence (AI), which is growing fast in both the research community and the general public. In contemporary dentistry, digital technologies such as cone beam computer tomography(CBCT),intra-oral3Dscan,3Dprinting,andpersonalizedtreat- mentplanninghavecometoplayalargerroleinbothresearchandpractice. Thesetechnologiesholdpromiseformorepredictable,objective,andeffective treatmentwhilereducingiatrogeniccomplications.Butforchangetooccur, datascientistsanddentalexpertsfromvariouscoherentdomainsmustwork togetherto developbig dataanalyticsthathavetranslationalvaluesandcan bedeployedinoralhealthcareandlifesciences.

Today,thenewtechnologiescanreplacehuman’seyesandhands,andAI canteach humanlearningprocessestothemachinetoclosetheeducational gaps. Many healthcare providers have integrated digital technologies into practice workflows, which reducethe dependenceon handskills andvisual recognitions.Computersoftwareisinitsinfancytointegratethesetechnolo- giestoimproveobjectiveperception,cognition,andactionwithexperience. Nevertheless, ML in dentistry is about developing a personalized precision practice and improving diagnosis and treatment planning from big data, literature, experience, and outcome-dependent learning. These also include the interrogationof large, complex‘omics datasets such as genetic lociand biomarkersforcraniofacialdisorders. Thepurposeofthisbookistoreviewthecurrentclinicalsystemsanddental researchinvolvingmachinelearningtoolsanditsassociationsamongvarious dentalspecialties.Theexamplesshowninthisbookrepresentasampleofthe opportunities and challenges for what is possible with the ML approach in v vi Preface contemporarydentistry.Wehaveinvitedexpertstocontributetheirreviewin thefollowingfourareas. MachineLearningforDentalImaging Dentists often read radiographs to detect craniofacial anomalies for identi- fying potential problems. However, mistakes can be made throughimaging examination and the diagnostic accuracy is dependent on the experience of the dentist. With a 3D image, this process turns out to be a stressful task becauseitisbasedonbigdataanduserexperience.Byusingmachinelearning to augment the image, diagnosis can be more accurate and objective, and treatmentscanbepersonalized. Acomputerdoesnotgettiredfromgruelingtasks,anditcantakeinagreat deal of data and process the information very quickly. First, the computer takes in a set of different radiographs labeled for healthy and unhealthy anatomies. Then, once the computer is given data of experts’ diagnoses, it can classify the patterns that are associated with certain disease or healthy anatomies. Thus, given a new patient’s radiograph, the machine can easily matchitwithpatternsthatwerefoundinthetrainingsetofexpertdiagnostics. There are already machine learning programs that are able to detect 2D panoramic features on the market, like denti.ai or dentistry.ai. In this book, wedelvedeeperintotherolethecomputerdoesfor3Dimagingsegmentation andlandmarkdetectionusingmachinelearninganddeeplearning.Chapters 1–5 describe the algorithms and provide examples for augmentation of craniofacial skeletal structures, facial surface recognition, and applications insimulationoforthognathicsurgery. MachineLearningforOralDiagnosisandTreatmentPlanning When conducting a medical diagnosis, a dentist would take in the patient’s chief complaint, history, conversation,and radiographs. Some of this infor- mation can be descriptive, and because of that, the dentist must be very experienced and in top condition to pay close attention to every word and its nuances from a patient’s narrative. Because it assembles these words to makeagooddiagnosis,dentistsmayeasilymisdiagnosetheirpatient.In2011, dentistswerefoundtohavea43%misdiagnosisrateoforallesions(Kondori etal.).Thisnumberisfrighteninglyhighandindicatesroomforimprovement. In medicine, there are various commercial software for auto-annotations of pathology images. Instead, the book focuses on clinical diagnosis and treatmentplanningusingAI. Natural language algorithm is part of machine/deep learning, which can support searching for key words and identify frequency and patterns of de- scriptivestatements.Chapters6–9providestate-of-the-artAIfororthodontic diagnosisandtreatmentplanning.Thisincludesfacialrecognition,cephalo- metric analysis, chart analysis, automated problem list and treatment plan- ning,characterizationofcraniofacialanomalies,anddecisionoforthodontic Preface vii tooth extraction.The AI couldsave time andstreamline anyprocesseswith improvedaccuracyinthefuture.

The authors also discuss about the shortcomings and potential pitfalls of employingartificialintelligence(AI)toareviewprocessthathasbeenmostly drivenbyhumanexpertsinthepast. Human genomics was one of the first areas of research to use big data. In Chap. 13, the researchers introduce how the machine learning and deep learningalgorithmsareusedindentalomicsstudiesforassociationanalysis between SNPs and complex diseases, CNV and SNV calling, and DNA methylation data.
