tomography (CBCT)is a revolutionary imaging modality that has changed numerous aspects of dentistry and has added great value to its diagnostic phase as well as that of orthodontics.CBCT three-dimensional (3D)imaging has the potential to improve the diagnosis and treatment planning.With the desire to enhance treatment by incorporating the highest technological advancements,CBCT has attracted signi ﬁcant attention.The potential applications in orthodontics have been recognized and appreciated.One of the most common selection criteria of CBCT in ortho-dontics is evaluation of impacted teeth [1e 4].It allows visualization in three dimensions,and the relation to adjacent teeth.For ex-ample,visualization of an external resorption of a maxillary lateral incisor due to impaction of a maxillary canine can be precisely evaluated [5].Additionally,CBCT can reveal the presence or absence of the canine,size of the follicle,inclination of the long axis of the tooth,relative buccal and palatal positions,amount of the bone covering the tooth,local anatomic considerations,and overall stage of dental development [6].Supernumerary teeth can be evaluated as well [7].Additionally,CBCT examination is recommended in patients with dentofacial deformities,including severe facial asymmetry or facial disharmony [8],cleft palate [9],patients withobstructive sleep apnea,and when a patient has an airway study [10e 15].The clear advantage of CBCT in these cases is evaluation of 3D structures through a 3D imaging modality.Additionally,the nasopharyngeal and oropharyngeal airway can be assessed in volume size and shape.Moreover,if temporary anchorage devices are planned,CBCT can assist in initial site assessment [16e 24],or temporary anchorage device site status evaluation [25e 27].Therefore,CBCT applications in orthodontics are plentiful.However,it is easy to be seduced by the sheer beauty of CBCT image reconstructions.Following the ethical principle of nonmale ﬁcence,practitioners in health care are supposed to minimize harm to patients.A cornerstone of radiation protection is to keep radiation “As Low As Reasonably Achievable,”the ALARA principle.There has been some confusion about CBCT and its imple-mentation in orthodontics.This could be due to overmarketing or limited understanding of the imaging technique itself.The purpose of this article is to present 10myths about CBCT in orthodontics and replace them with facts about this imaging technique.The 10myths of CBCT in orthodontics are (1)CBCT exposes orthodontic patients to low radiation;(2)if daily background radiation is 8m Sv,any CBCT acquisition would be justi ﬁed because it has the effect of only few days of background radiation;(3)we must have totally new 3D CBCT cephalometric analyses that replace two-dimensional (2D)standardized analyses;(4)CBCT can replace impressions for orthodontics and be as accurate;(5)volume rendering is suf ﬁcient to display external root resorption;(6)CBCT changes the ﬁnal outcome of orthodontic treatment;(7)Boards of Orthodontics will eventually adopt CBCT for all orthodontic records and superimpositions;(8)CBCT is suf ﬁcient

Federation of Orthodontists 1(2012)e3e e8modality to examine the temporomandibular joints (TMJ);(9)if CBCT is ordered,the orthodontist is at liability risk for any pathology in the scan;and (10)CBCT is an orthodontic practice builder.2.Myth 1CBCT exposes orthodontic patients to low radiation.2.1.FactThe effective dose of an imaging modality is a commonly used term in radiation biology and presents a numeric value in micro-Sieverts (m Sv).It provides a mechanism for assessing the radiation risk from partial body irradiations in terms of data derived from whole body irradiations.It is calculated as the weighted average of the mean absorbed dose to the various body organs and tissues,where the weighting factor is the radiation risk for a given organ (from a whole-body irradiation)as a fraction of the total radiation detriment [28].The effective dose of CBCT is quite ﬂexible and the range is much wider than other imaging techniques used in dentistry.Table 1describes that the effective dose of panoramic radiography is esti-mated to be 2.7to 23m Sv [29e 34].Cephalometric radiography effective dose is approximately 1.7e 3.4m Sv [35].On the other hand,effective dose range of CBCT is very large and can be anywhere from 20to 1000m Sv,depending on the machine,ﬁeld of view,and selected technique factors [29,31,34,36e 40].Only one CBCT machine with large ﬁeld of view exceeded 1000m Sv [36].Each CBCT device uses different settings,which results in a wide range of the effective dose.The latest ﬁndings report that this wide effective dose range of different CBCT devices is strongly related to ﬁeld size [41].Increasing the ﬁeld of view would increase the effective dose [31].Alternatively,reducing the volume size is perhaps the best way to reduce radiation exposure for the patient.For example,an impacted tooth does not require imaging of the whole head.A smaller volume of 40Â40mm,for example,may be appropriate.This has the potential bene ﬁt of increased resolution of the images because most CBCT machines that provide different scan volume options usually use larger voxel size on large ﬁeld of view scans and smaller voxels in smaller ﬁeld of views.Fortunately,CBCT effective dose is comparatively smaller than traditional medical CT imaging technique [42e 48].In other words,CBCT effective dose is higher than conventional panoramic and cephalometric radiography,but less than conventional CT.No approach regarding CBCT radiation risk assessment in chil-dren in particular has been examined yet.However,a CT study found that the smaller mass of children caused the corresponding effective doses to be higher than those in adults undergoing similar CT examinations [49].Generally,thyroid shielding with a leaded thyroid shield or collar is strongly recommended for children and pregnant women d these patients are particularly sensitive to radiation [50].This reduces the risk because lead shielding reduces the effective dose [38].3.Myth 2If daily background radiation is 8m Sv,any CBCT acquisition would be justi ﬁed because it has the effect of only few days of background radiation.3.1.FactThere are certainly other sources of radiation from natural sources and human activities besides diagnostic imaging.Natural background radiation,terrestrial radiation,and long ﬂights at high altitudes constantly expose humans to radiation.The annual global per capita effective dose due to natural background radiation sources alone is estimated to be about 2400m Sv at sea level,and may be of wide range between 1000and 3000m Sv.Consequently,the natural background radiation is estimated to be about 8m Sv per day.It is correct that a certain CBCT effective dose of 50m Sv is equivalent in magnitude to 6or 7days of background radiation;however,the effect is entirely different because the acute nature of CBCT exposure of few a seconds is unlike the very low,continuous,and chronic exposure of background radiation.Radiation hormesis concept suggests that very low doses of continuous and chronic ionizing radiation that are equivalent to natural background levels are,in fact,bene ﬁcial.This is because they stimulate the activation of repair mechanisms that protect against the disease process [51,52].Therefore,it is better to adhere to the radiation protection concept of ALARA [53],than comparing CBCT to background radi-ation,a source that cannot be controlled anyway.Ideally,CBCT should be acquired in orthodontics when a 3D evaluation is required.Otherwise,conventional 2D imaging might be suf ﬁcient.For example,ordering a full head CBCT scan just to build cephalo-metric and panoramic radiographs is not justi ﬁed,because these two radiographs could have been ordered without exposing the patient to the additional radiation.As previously mentioned,a full head CBCT effective dose,in some machines and settings,can be much higher the combined dosage of digital panoramic and ceph-alometric radiographs.Consequently,ordering the higher radiation CBCT just to build panoramic and cephalometric radiographs is not consistent with the ALARA principle,and could not be justi ﬁed if compared with the myth of “few days of background radiation.”Additionally,it is judicious to take advantage of the 3D capability of CBCT after adopting this technology.According to Buttke and Prof ﬁt [54],only 15%of orthodontic patients are adults.Therefore,because most orthodontic patients are children,it is important to emphasize that the ALARA principle applies even more critically in the majority of orthodontic patients who are more sensitive to radiation and who have long years to live whereby radiation risks may manifest in their lives [55,56].4.Myth 3We must have totally new 3D CBCT cephalometric analyses that replace 2D standardized analyses.4.1.FactPanoramic and cephalometric radiographs are standard ortho-dontic records.Introducing new CBCT cephalometric analyses require some new landmarks,planes,and angles [57].CBCT also requires different analyses that may be dif ﬁcult to memorize and apply.Table 1Effective doses of basic radiographic imaging versus CBCT and medical head CT Imaging modalityEstimated range of effective dose (m Sv)Digital panoramic radiography 2.7e 23Digital cephalometric radiography 1.7e 3.4CBCT 20e 1025Head CT2000A.Abdelkarim /Journal of the World Federation of Orthodontists 1(2012)e3e e8e4Realistically,few orthodontists perform tracing and full analyses on all their patients.In fact,the availability of2D analyses of conventional lateral cephalometric radiograph may not make a signiﬁcant difference to the treatment decisions[58].Tracing the sagittal and frontal cephalometrics and analyzing CBCT acquisitions are unquestionably recommended.However, performing CBCT cephalometric analyses in three dimensions (including new numeric and angle values that are not present in conventional analyses such as Downs,Steiner,Ricketts,McNamara, and Tweed)may not be necessary.The3D CBCT should beneﬁt clinicians in many different ways, other than complicated3D cephalometric analyses.This modality offers three orthogonal images of oral and maxillofacial structures (axial,sagittal,and coronal views),and any otherﬂat and curved slices of variable thickness.Therefore,3D superimpositions,asses-sment of treatment outcome,and growth change evaluation in three dimensions can be performed[59e63].Surgical outcomes can be evaluated,and this can be of great value for the orthodontist and the patient[64,65].Lastly,soft tissue change can be visualized and evaluated in the short-and long-term in cases of orthognathic surgery[66,67].Therefore,sophisticated3D analyses may improve the diag-nostic records in some cases,but they are questionable to be valuable as a new standard.5.Myth4CBCT can replace impressions for orthodontics and be as accurate.5.1.FactEven though CBCT digital“models”are sometimes accurate for making linear measurements for overjet,overbite,and crowding measurements[68],they are unlikely to be accurate for clear tray and orthodontic wire fabrications as conventional impressions.It takes only one amalgam restoration to create“beam hard-ening”artifact[69],which creates distortion.Beam hardening occurs around dense objects such as metal brackets and bands[70]. Other CBCT image artifacts include cupping,dark bands,noise,and scatter.Although CBCT acquisition during orthodontic treatment is possible,the images would be distorted due to the beam hardening and scatter around orthodontic appliances.Another signiﬁcant limitation for these tasks is possible patient movement,creating motion artifact during the relatively long scans,especially in young orthodontic patients.All these limitations of CBCT technique should be considered as they may reduce image quality.In reality,image quality itself is not similar among different CBCT machines.This was found in testing different CBCT machines in detection of simulated canine impaction-induced external root resorption in maxillary lateral incisors,a common application of CBCT in orthodontics[71].Those who are not familiar with CBCT images may not be able to differentiate between different machines,in regards to image quality.These artifacts are not noted in digital or conventional impres-sions.One may argue,however,that CBCT will continue to improve to where it will be as accurate and precise as impressions.But the numerous CBCT machines already installed will not be replaced with newer ones to replace these impressions.6.Myth5Volume rendering is sufﬁcient to display external root resorption.6.1.FactLike any other volumetric imaging,CBCT interpretation requires the use of computer software to provide multiplanar reformatted images and supplementary3D visual representations such as volume rendering.The volume rendering,usually provided by the software automatically,is similar to architectural exemplary illustrations that provide the exterior layout but not the interior details.Three-dimensional volume rendering images can only be utilized as an adjunctive aid where it can help the orthodontist,as well as a great visual aid for the patient or parent to understand the treatment plan.However,these attractive illustrations are computer-generated and are created upon software algorithms that may not be reliable.Selecting the volume rendering may obscure normal anatomy or create artifacts that are not present.Unfortunately,numerous presentations of CBCT images include the volume rendering only.This rendering may produce false-negatives or false-positives and is not sufﬁcient to identify presence or absence of mild external root resorption that may be present on a maxillary lateral incisor,for example,due to impaction of a maxillary canine.Evaluation of multiple slices of the scan is necessary.Perhaps some clinicians opt to present the volume rendering because evaluating the axial,coronal,and sagittal views of the scan is more “technically demanding.”Nevertheless,examination of the scan through these views is generally required because this has higher sensitivity and speciﬁcity.7.Myth6CBCT changes theﬁnal outcome of orthodontic treatment.7.1.FactCBCT increases accuracy of orthodontic diagnosis.Increasing diagnostic accuracy eliminates false-positive and false-negative results.Also,the treatment plan becomes more appropriate for speciﬁc cases.This may change theﬁnal outcome in some cases,but not always.Until now,there have not been randomized clinical trials that examine whether there is a favorable difference between orthodontic patients who were imaged by CBCT and those who were not.The effects of information derived from these images in altering diagnosis and treatment decisions have not been estab-lished in several types of cases[72].This certainly does not mean that there is no beneﬁt of CBCT for speciﬁc cases such as impacted and supernumerary teeth,tempo-rary anchorage device site assessment,pharyngeal airway assess-ment,craniofacial deformities,cleft palate,identiﬁcation of root resorption,and orthognathic surgery planning[72].Moreover,retrospective evaluation of existing CBCT data may,in many cases,provide additional understanding of numerous aspects of orthodontics.At this point,it is still arguable whether CBCT in orthodontics always provides more diagnostic information than panoramic and cephalometric radiographs,changing theﬁnal outcome,in order to justify its routine use in all orthodontic patients.In fact,additional information or lack thereof cannot be discovered unless comprehensive CBCT evaluation is performed.It also should be remembered that incorporating CBCT routinely in regular orthodontic practice increases the collective dose to orthodontic patients as a whole,thereby increasing the probability of deleterious effects of radiation in a group that is relatively sensitive to radiation.A.Abdelkarim/Journal of the World Federation of Orthodontists1(2012)e3e e8e58.Myth7Boards of Orthodontics will eventually adopt CBCT for all orthodontic records and superimpositions.8.1.FactAs of today,these boards have not recommended CBCT for all cases.It is,however,likely that3D imaging will be required when it provides useful information that meets the treatment needs.For example,in2000,a position paper by the American Academy of Oral and Maxillofacial Radiology(AAOMR)recom-mended that some form of cross-sectional imaging be used for most patients receiving implants[73].Today,CBCT is the preferred imaging modality for implantology.Fortunately,most elderly patients receiving implants are less sensitive to radiation than most orthodontic patients who are typically young.In another position paper by the AAOMR and the American Association of Endodon-tists,CBCT was recommended for selected,but not all,cases in endodontics[74].It was recommended that CBCT must not be used routinely for endodontic diagnosis or for screening purposes in the absence of clinical signs and symptoms[74].In orthodontics,the frequency of CBCT use is likely to be equal to endodontics,unlike implant imaging,where CBCT is used more frequently.Selection of CBCT in orthodontics is clearly case speciﬁc, and wise clinical judgment should be used.In other words,CBCT is justiﬁed in selected,but not all cases in orthodontics[75].9.Myth8CBCT is sufﬁcient and is the best imaging modality to examine the temporomandibular joints(TMJ).9.1.FactCBCT is excellent for imaging of the bony component of the temporomandibular joints,especially if compared with panoramic radiography.Therefore,it is a valuable diagnostic tool for TMJ evaluation[76e78].However,TMJ complex is composed of bony and soft tissue structures.Unfortunately,CBCT does not map out the muscle structures,and the articular disk cannot be visualized[79].The inability to visualize the articular disk and internal derangements through CBCT imaging is a signiﬁcant disadvantage for TMJ imaging.Although degenerative bone changes(which can be depicted by CBCT)may be correlated with disk displacement without reduction [80],there is actually a poor correlation between condylar changes observed on CBCT images and pain,and with other clinical signs and symptoms of TMJ of osteoarthritic origin[81].Magnetic resonance imaging(MRI)is the imaging technique of choice if an evaluation of the articular disk is required[82,83]. Although CBCT can provide valuable information about TMJ bony changes,it is not the best imaging modality for TMJ evaluation.At least,it is not sufﬁcient to create a comprehensive radiographic evaluation of the TMJ.10.Myth9If CBCT is ordered,the orthodontist is at liability risk for any pathology in the scan.10.1.FactLately,there has been considerable concern among dental practitioners regarding the liability of reporting any pathology or incidentalﬁnding present in the CBCT scan.Dentists are not typi-cally trained on CBCT interpretation in dental schools,so a full evaluation of CBCT scans can be a difﬁcult task.Even though the radiographic anatomy of CBCT is the basic structure of the skull, differentiation between a patient with a normal anatomy and an abnormality can be challenging.Until now,there have been mixed opinions on this issue.No deﬁnitive guidelines have been formed at this time.Turpin [84]and Jerrold[85]advise that orthodontists,if ordering CBCT imaging,are liable for the interpretation of the CBCT volume.But it should be remembered that potential risks for the orthodontist include unidentiﬁed pathology in traditional radiographs and possibly photographs.If examined by an oral and maxillofacial radiologist,liability risks can be avoided.Afterwards,other risks in orthodontics may be avoid as well,because CBCT contributes to accurate diagnosis and, therefore,improved treatment plan[86].Some argue that a legal document can eliminate the risk.The patient can sign an informed consent that no interpretation of the volume would be performed,and only the prescribed diagnostic task would be evaluated.There is less discussion regarding the moral consideration of fully evaluating the CBCT for the patient’s beneﬁt.Another way to reduce the risk is to use a smallerﬁeld of view. This actually has another beneﬁt of reduced effective dose.11.Myth10CBCT is an orthodontic practice builder.11.1.FactThis is probably the most ironic and debatable myth.One may claim that CBCT provides superior images that facilitate treatment plan presentation.As previously said,some believe that CBCT has the potential of replacing conventional impressions and intraoral and extraoral photos,and subsequently,one CBCT scan can be sufﬁcient for initial orthodontic records.Furthermore,some believe that patients are attracted to this technology.However,this expensive technology that involves ionizing radiation is unlikely to replace conventional impressions and be as accurate and sufﬁcient to create comprehensive diagnoses and build wires and clear trays.Additionally,progress andﬁnal photos and radiographs cannot be compared with a single3D radiographic scan.For consistency,an initial CBCT scan would require an addi-tionalﬁnal scan for comparison.In this case,the radiation dose is doubled,assuming no acquisition retakes are performed.Many parents are aware of ionizing radiation risks and are unlikely to be interested in higher radiation for their children if given the choice of whether or not to use CBCT.Three-dimensional evaluations through CBCT should continue to evolve in orthodontics.Unfortunately,this technology is not ubiquitous yet.At this point,it is still signiﬁcantly more expensive than other technologies in standard orthodontic practice.As a result,CBCT may not be an orthodontic practice builder for everybody.12.ConclusionsCBCT is a valuable imaging modality in orthodontics.Its appli-cations in thisﬁeld have been widely recognized.It is time to reevaluate the validity of some erroneous ideas that are based on blind faith and overmarketing,instead of scientiﬁc evidence and common sense.A.Abdelkarim/Journal of the World Federation of Orthodontists1(2012)e3e e8 e6The risk e beneﬁt ratio of CBCT is usually favorable.Due to numerous overlapping carcinogenic factors in human life,it is impossible to assess the long-term stochastic effects of radio-graphic examinations.For that reason,the concept of ALARA,sug-gesting that radiation should be kept“As Low As Reasonably Achievable,”should be adhered to,rather than justifying CBCT acquisitions by comparing their dose exposure to background radiation.Replacing impressions with CBCT,ordering it for every patient,and claiming that it would build the orthodontic practice are tactics that should be debunked.Once acquired,orthodontists are encouraged to evaluate the scan thoroughly,primarily for the patient’s beneﬁt.Because acquisition of CBCT is case speciﬁc,each patient may beneﬁt differently,but some patients may not beneﬁt from the procedure.In addition,CBCT usage will ultimately result in more validated research being performed and will become an advantage of our profession with secondary tangential beneﬁts to those undergoing orthodontic therapy.References[1]Botticelli S,Verna

训练

训练
今天，蒲州育英学校的足球队员来到上陡门球场训练。

练习了一会，便开始比赛了。

我、潘书恒、张恒、朱江浩和俞炯翰组成一队，对方是翁家宝张翔、王政、陈赛驰和上官弘尚。

比赛开始了，对方发球，一发球，我们便冲上去抢球，可没想到陈赛驰用脚后跟将球向后一顶，传给了翁家宝，他带球向前冲，我们集体回防，担心他连过四人再射门，他带着带着，忽然外脚背一拨，传给陈赛池，可是陈赛驰却没接住，我们松了口气，便开始反击了，俞炯翰把球扔给了我，我传给张恒，张恒传给潘书恒，他一脚大力射门，没进，非常可惜。

我们往回跑，只见王政迅速将球扔给翁家宝，翁家宝用最快的速度向前带球，只过了三十秒，便听哨声响起，球进了，这球进的犹如电光火石一般，整个过程不到一分钟，我们都惊讶地合不拢嘴。

后来他们又进了一个，我也进了一个，2:1.我们输了。

看来，我们的球技还不行，得多多练习啊！
