The Bottom Line
Lasershavebeen increasing inpopularity inden-talhygienepractice.Althoughtraditionalscalingandrootplaning(SRP)anddailyself-carebythepatienthavebeenshowntobeeffectiveinreducinginflam-mationandprobingdepthsandincreasingclinicalat-tachment,challengesassociatedwithdeeperpockets,rootmorphologyanddifficultaccessareasdecreasethe likelihood of healing following nonsurgical peri-odontaltherapy(NSPT).Adjunctssuchasantimicro-bials and lasers have been advocated to overcomethese limitations. Lasersmaybe used in the treat-mentofperiodontitisasamonotherapyorasanad-junct toSRPduring initial periodontal therapy, sur-gery,orperiodontalmaintenancetherapy;however,thisarticleaddressestheiruseasanadjuncttoSRPinNSPT.
Severaltypesof lasersareusedinthetreatmentofperiodontalandperi-implantdiseases:diodelasers(DLs)(809to980nm),Nd:YAG(1064nm),Er:YAGand Er,Cr:YSGG (2940 and 2780 nm, respectively)andtheCO2laser(10,600nm).1InNSPT,laserthera-pyisadvocatedforsulculardebridement,alsoknownassoft tissuecurettage,and forbactericidaleffectswithintheperiodontalpocket.Unlikeothertherapeu-ticproceduresusedbydentalhygienistsanddentists,thereisnostandardacceptedprotocolfortheuseoflasers.Asageneralrule,theperformanceofagiv-en laser is governed by its absorption, or depth ofpenetration intothetissues,andtheabsorptionde-pendsonthewavelength.2DiodeandNd:YAGlasersaredeeplypenetratingwhereasEr:YAG,Er,Cr:YSGGandCO2penetratesuperficially.Oneexceptiontothisgeneral rule is thephotodynamic therapy (PDT) di-odelaser(660to810nm),alow-powerlaserusedincombinationwithaphotosensitizingagentforantimi-crobialpurposesonly;therefore,thisarticledoesnotaddressPDT.Also,theresearchfindingspresentedinthisarticledonotapplytothelaser-assistednewat-tachmentprocedure(LANAP)usingtheNd:YAGlaser,asitisaspecificprotocoltrademarkedbyonecom-pany, requiringa fullyearof training,andreservedasmoreofadefinitivesurgicalprocedurefordentists

Based on the findingsof these 2 studies, the ensuing conclusions can bedrawn:
• Although the ND:YAG laser resulted in a0.41 mm gain in attachment, comparedwithSRPalone,theoveralllevelofcertain-tyoftheevidencewaslow.Only3studiescouldbeincludedinthemeta-analysisandtheriskofbiaswasmoderatetohigh.
• Moreover,theresultsofbothofthesesystematicreviews andmeta-analyses, aswell as theADAscientific panel’s systematic review and meta-analysis, support the Statement on the Efficacyof Lasers in the Non-Surgical Treatment of In-flammatory Periodontal Disease published bythe American Academy of Periodontology whichstates,inpart,thatthereisminimalevidencetosupportuseofalaserforthepurposeofsubgingi-valdebridement,asanadjuncttoSRP.4

Abstract:Ameta-analysiswasconductedtoinves-tigatewhethertheuseofNd:YAGlaseradjunctivetoscaling root planing (SRP) could provide additionalbenefitscomparedtoSRPaloneinpatientswithchron-icperiodontitis.Themeta-analysiswasperformedac-cordingtothePRISMA(PreferredReportingItemsforSystematic Reviews and Meta-analysis) statementand the recommendationsof theCochraneCollabo-ration. A literature searchwas performed on seven

Oral Health Concerns
Oral hygiene is imperative in LTCFs, since, nat-ural teeth are more susceptible to dental caries,periodontaldisease,demineralization,andgingivalrecessionduetoage,diet,genetic factors,brush-inghabits,andlifestylefactorsovertime.8,13-18,26-32Morethanhalfofolderadultpatientshaveenamelandrootsurfacecaries,placingthematthehighestriskdue togingival recession,heavyconsumptionof fermentable carbohydrates, poor oral hygieneanddecreasedfluorideexposure.32,33Morerecurrentcaries is evident along the coronal surfaces frommarginalbreakdownorotherfailingrestorativema-terials;fermentablecarbohydratescanalsocollectaround crowns, bridges, and implants, leading tocariouslesions.34
Investigatorshavereportedthatperiodontaldis-ease occurs at a rapid pace for the LTOPs, oftenworsening with age.2,34-37 Twenty-three percent ofthe total older population has severe periodontaldisease,withsymptomsofinflamed,painfulgingi-valtissue,recessionandmobility.38Periodontaldis-easeintheLTOPisaresultofseveralfactorsinclud-
LTOPswith removable prosthetics are at an in-creased risk of oral diseases and lesions, includ-ing oral candidiasis anddenture stomatitis result-ing from Candida albicans.37,40,41 A cross-sectionalstudy,withanaverageageof85,aimedtoinves-tigate fungal infections on 233 denture wearingLTOPs.41Swabswereperformedontheparticipants’buccal mucosa to determine themicro floral sta-tus.41 Results demonstrated that oral candidiasisandhigheroralyeastcountsarecommonlyseenintheLTOPandareattributedtolackofdailydenturecleaning.41

Barriers to Oral Care

NursesarerequiredtocompletesectionsKandLoftheMDSthatpertaindirectlytooralhealth.42Thesesectionsaresupposedtotriggerintervention,care planning, and improvements in oral health.42Still,therearenumerousconcernsaboutthequal-ity of oral care received, since payroll for nursestendstoaccountforthebiggestoverheadandfundsarelimited.7Limitationsandrestraintsarealsoseenas feworalhygieneorhealthconcernsare identi-fied; the MDS simply records what services werecompleted and cannot effectively enforce suitablecare to every patient.42 It has been shown thatnurses canbedishonest aboutdaily routines thathave been carried out with the patient, includingoralcare.24Furthermore,MDSscoresaretakenintoaccount for an LTCFs overall evaluation, andpoormarkscouldjeopardizethefacility’sfundingagen-cies and regulation records.24 Since oral hygienemarksontheMDSscorearenotconsideredvitaltothe scoringprocess, an incomplete recordof careoftenoccurs.24
Multipleinterviewswithnursingstaffhavegiventhemost insight as to why care of the oral cav-ity is not given more emphasis in LTCFs (TableII).27,28,42,50 Many nurses found that oral hygienewasminimally covered in their education; only 1to3%of thenursingworkforce is trained inolderadult oral care.27,28,42,50 The small amount of timespent learningaboutoral care for the LTOPmadeitseemlessinterestingandunimportant,withless

RDHsfacemultiplebarrierswhenitcomestopro-viding increased access to care for the LTOP. Fewstatesareimprovingtheneedtoprovidebetterac-cesstocarefortheLTOP.Only45%ofU.S.statesand territories have legislative policiesworking toprovide increased access to the LTOP.61 Currently,governing legislation allows a RDH to practice inan LTCFwithout direct supervision from a dentistinsomestates;however,whatservicesareprovid-edandrequirementsoftheRDHvary(TableIV).62However, RDHs receive limited specialized educa-tiontowardsworkingwiththeLTOP.63-66Dentalhy-gienecurriculavarybyschoolprograms,andoften,students reportnot receivingenougheducation intreating theLTOP.63,64Most instructive lessonsandclinical education for dental hygiene students arefocusedoncaringfortherelativelyhealthy,mobileolderadultpatient;veryfewcoursesoffersupportfocusedon theLTOP.65Noneof theover500resi-denciesestablishedbytheAmericanDentalEduca-tion Association (ADEA) specialized in older adulttraining.2TheCommissiononDentalAccreditation(CODA) requires dental hygiene students to workwith the older adult population and community-basedprograms;however,it isnotmandatedthatthey work in LTCFs.66 Adapting school curriculumischallengingduetolimitedprogramfundingthatmust be shared among multiple subject mattersandtopics;however, facultywithindentalhygieneschoolsneed todemonstrate increased interest inregardtooralcarefortheLTOP.66

Aprimarygoalofradiographyistorenderadiag-nosticimagewhilekeepingthedosetothepatientaslowasreasonablyachievable.Thisstudycomparedthetechnicaloutcomeof2rectangularcollimators:onewithtechniqueenhancementfeaturesthatret-rofittedtothetubeheadandonethatinsertedintoa circular collimator. In addition, subject feedbackwassolicitedontheuseandpreferenceofthecol-limators.
Whenthedeviceswerecomparedbasedontech-nicalperformancetherewasnotaconsistentpatternseenwhereonedeviceoutperformedtheotherwithrespecttopacketplacement,verticalangulationorhorizontalangulationerrors.However,theenhanceddevice produced significantly fewer overall errorswhencomparedtotheuniversaldevice.Thetypeoferrorthatwasprimarilyreducedwiththeenhanceddevicewascollimatorcutting.Thisfindingisincon-trasttothatreportedbyZhangetal.5Zhang’sstudyreportedanincreaseincollimatorcutsandsuggest-edthatthedevicemaybemodifiedtoincreasetheaperture opening in the device.5 Interestingly, thecurrentstudydiscoveredthattherewasminimaldif-ference between the devices in thenumber of er-rorsrequiringaretaketorenderadiagnosticimage.
Question #2 asked the subjects (n=17) to listwhich enhancement features (audible and visualsignals,magneticring),ifany,werehelpfultothemastheoperator.Eighty-twopercentchosethevisual(lighted)signal,71%listedthemagneticposition-ingring,and35%listedtheaudiblesignalasbeinghelpfultothemduringexposures.
Questions3and4explored thechoicesofsub-jectsregardingimpactonimagequalityandeaseofuse.ResponsestoQuestion3indicatedthatfifteensubjectsfeltthatusingtheenhanceddevicewouldproducebetter quality images.One subject chosetheuniversaldeviceandonesubjectremainedun-decided.Question4askedthesubjects(n=17) tomakeachoiceastowhichofthetwodevicestheyfound easier to use. Sixteen chose the enhanceddevice while 1 remained undecided. No subjectschosetheuniversaldevice.
Question5askedthesubjects(n=17)tochoosea device basedon their overall preference and toelaborateastowhy.Sixteenresponseswereinfa-voroftheenhanceddevicewhileonesubjectpre-ferredtheuniversaldevice.Explanationsthatsub-jectsprovidedforpreferenceoftheenhanceddevicewerethatitprovidedconfidencetotheoperatorre-gardingexposureofaqualityimage,lesstimeandeaseofuse.Theonesubjectthatpreferredtheuni-versaldevicemadethisdecisionbasedonfamiliar-itywiththedevice.
Thus,most of the collimator centering errors thatweremadedidnot influencethediagnosticqualityoftheimage.Incontrasttothecurrentstudy’sre-sults,ParksetalfoundthatuseoftheRinn®Snap-onrectangularcollimatingdeviceresultedinasta-tisticallyhighernumberofretakeswhencomparedto theotherdevices tested(i.e.snap-a-ray/round,XCP®/BAIparalleling/round,snap-a-ray/rectangular,XCP®/BAIparalleling/rectangular,XCP/BAIparallel-ing/Rinn®Snap-on,andPrecision/rectangular).7Al-thoughParksetaldidnotofferanexplanationforthis finding, the greater number of retakesmightbeattributed to theattachmentof the rectangularRinn®Snap-ondevicetothealignmentring.Inad-dition, Parks et al didnot provideadescriptionoftheapertureopeningforthe16inchFFDrectangularcollimatorusedinhisstudy,whichlimitsacompari-sonof his findings to the current study.7 Althoughnot evaluated in this study, use of the XCP-ORA®mayreducethenumberofcollimatorcutsduetothenotchedaimingring.Thiscouldbetestedinfuturestudies.
Additionally, the current study found that moreerrorsoccurredinposteriorprojectionscomparedtoanteriorandbitewingprojectionsregardlessof thedeviceused.Theauthorsofthisstudybelievethatthisphenomenonislikelyduetothepresenceofan-atomicalobstacles(i.e.tongueandcheeks)result-inginthelesseningofvisualconfirmationofproperplacement regardless of the device used. Parks etalreportedthatfilmplacementerrorswerenotaf-fected regardless of collimation technique used oroperatorskill.6
userfeelsthatthedevicehelpsthemtoachievedi-agnosticimageswithgoodimagequality.Thesurveydataindicatedthatthemajorityofsubjectslikedtheenhancement featuresof theenhanceddeviceandfeltthattheenhanceddevicewouldrenderabetterdiagnosticimage.Subjectswereabletoworkfasterwiththeenhanceddeviceandreportedpreferenceforthisdevice.Zhangetalfoundthatstudentsreportedagreatereaseofusewiththeenhancedrectangulardeviceencompassingamagneticalignmentringasopposed to the freely adjustable universal rectan-gular collimator.5However, contrary to this study’sfindings,ZhangetaldidnotseeareductionintimenecessarytocompleteanFMX.5Thisstudyshowedimprovement in time efficiency (approximately 4mins)aswell asa reductionofoverall errorswiththeenhanceddevice regardlessof the fact that inboth study settings, subjects had no previous ex-periencewiththedevice.ThesubjectsinthisstudydidhavepriorexperienceusingtheXCP-ORA®whichmayhavecontributedtoashortlearningcurveforputtingtheinstrumentstogetherandusingthemforradiographic exposures. Thirty-five percent of thestudysubjectsreportedaninaccurateorfalsecon-firmationofthelightandaudibleenhancementfea-turesof theenhanceddevice(Figure9).Similarly,Zhangetalfoundthatfalsesignalingwascommon.5Asaresult,operatorsshouldbecautionedthatfalsesignalsmayinfluencenegativelyaccuratealignmentofthex-raypositionindicatingdevice(PID).
It appears that the enhanced device’s enhance-mentfeaturescouldhaveplayedapartinthereduc-tion of collimator centering errorswhen comparedto the universal device. This study found that thenewly modified enhanced device produced fewercollimator centering errors than the freely adjust-able universal rectangular device. These findingscontradictthefindingsofZhangetalwhousedthe
originallydesigned(unmodified)enhanceddevice.5Zhang reported that use of the original enhanceddevice produced almost four times the number ofcollimatorcenteringerrorsaswiththeuniversalde-vice.5 The 35% larger beam area of themodifiedenhanceddevicecompared to theoriginally testedprototypemaybethereasonforthisfinding.Whenimagequalitywasassessed, thereappeared tobeslightly fewererrorswith theuseof theenhanceddevicebuttheseerrorsdidnotrenderdiagnosticallyunacceptableradiographs.Thus,thelargercollima-torareaoftheenhanceddevicemayhavereducedthenumberof collimator centeringerrors,but thedatashowedthattheenhanceddevicedidnotpro-ducemorediagnostically acceptable imagesand itmayhavebeenattheexpenseofincreasedpatientexposure.
ItisimportanttonotethattheexposureareaoftheRinn®universaldevicecomplieswiththeNCRPstipulationthatrectangularcollimatedbeamsshouldnotexceedthedimensionoftheimagereceptorbymore than twopercentof the source-to-image-re-ceptordistance(SID)andhasbeenmeasuredasonepercentoftheSID.8TheTru-Align™websitesuggeststhattheenhancedcollimator“reducesthebeamsizetoapatternthatisonlytwopercentlargerthantheacquisition device.”9 But according to a previousstudy,themeasureddimensionswerereportedtobe4%largerthantheSID.8Themanufacturer’sclaimofa50%reductioninexposureareacomparedwitha round collimator appears to be overstated com-paredtothestudybyJohnsonetal.8,9Johnsonetaldeterminedthata18%reductioninexposureareaoccurredwhentheenhanceddevicewascomparedtoa6cmroundcollimator.8Similarly,theclaimofa60%reductioninpatientdoseisnotsubstantiat-edwithactualmeasurements.8Thus,theuseofthedesignation“rectangularcollimation”hasanimplicit

When interpreting the results of this study, it isimportant torecognize the limitationsof thestudydesign.First,theimagesfromthetechnicalperfor-mance component of this study were exposed onDXTTR manikins. Tongue movement and patientcooperation, factors thatoften influence imageac-ceptability,werenotabletobefactoredinwhende-terminingthetechnicalperformanceofthecollima-tors.Thus,thenumberandtypesoferrorsseenwithDXTTRsmaybedifferentfromlivepatients.Second,onlyabouthalfofthestudypopulationchosetopar-ticipate in the study. This may have introduced asubjectbias.Thus,acomparisonofnon-participantswithstudyparticipantswouldhavehelpedtodeter-mineifdifferencesingroupsexisted.Althoughcom-parisonsbetweengroupswerenotdone,attemptsweremadetostandardizeaminimumcompetencylevelforallsubjects.Forexample,allsubjectshadpassedtheirpreclinicalcompetencyandparticipatedin2semestersofradiographicclinicalpractice.Third,technicaldifferencesbetweenthe2collimatorswerebasedontheradiographicperformanceskillsofthesubjects. Asmentioned, the subjects hadminimalclinical experienceswith patients. Performance re-sultsofthedevicesmayhavebeendifferentiftheywere used by experienced clinicians. Presumably,experiencedcliniciansaremorelikelytoidentifyandproblemsolve incorrect placement of devices. Theauthors also made the observation that tubeheadinstabilitymay influence the interlockingnatureoftheenhanced rectangulardevicewith itsmagneticring.Enhanceddeviceweight (n=8)and tubeheadinstability(n=4)reportedbythesubjectsmayhaveoccurredduetoweightofthedevices.Weighingofthedevicesrevealedthattheuniversalmethodwas
heavier than the testmethod. Another interpreta-tionmightbethatthesubjectswerereferringtotheweight of themagnetic aiming ring usedwith theenhanceddevicewhichisheavierandbulkier.Inad-dition,thegreatercollimatorlengthoftheuniversalmethodmayhavecontributedtothetubeheaddrift.

Regarding oral health indicator #3, sealant uti-lization needs to increase.

Most importantly, results of this study revealedthe contribution dental hygienists make to thishealthcenter,providingcloseto40%ofallservices.Overall, preventive utilization has increased from39%to47%,andurgentcareutilizationshowedaslightdecline from15%to13%.Dentalhygienistsat this FQHC play a critical role in the success ofpatientoralhealthoutcomes.Thedentalhygienist’sroleinoralhealthpromotioninthisclinicencompassamultitudeofservices:oralcancerscreenings,nu-tritionalguidance,bloodpressurescreenings,smok-ingcessation,thedeliveryofperiodontalcare,andcounseling on the connection between oral healthandgeneralhealthforat-riskpopulations.Evidenceshowsthatdentalhygienistsplayanintegralpartinthesuccessinmeetingtheoralhealthgoalssetforthinthisreport.

Thedescriptivestatisticsofthestudysamplearepresented in Table I. Therewere 140 participants,57.1%ofwhomweremen,46.4%ofwhomwere25to44yearsand96.4%ofwhomwerenon-Hispanicwhite. The racial characteristic of the survey sam-ple is representative of Appalachia-West Virginia.Amajority of the participants (83.6%)had a highschool education or above. There were 42.9% ofparticipantswhoreportedanincomeof$25,000to$50,000.Morethanhalfoftheparticipants(53.6%)reportedcurrentsmoking.Therewere46.4%ofpar-ticipantswhoreportedasomewhatpoororverypoororalhealthstatus,and17.1%whoreportedapainlevelof10ona0to10scale.Intermsofdentalfear,therewere47.1%withmoderatetohighdentalfearscoreson theDental FearSurvey.
