  • INDIAN DENTAL ACADEMYLeader in Continuing Dental Education www.indiandentalacademy.comwww.indiandentalacademy.com
  • PERIODONTAL DISEASES Estimated by signs & symptoms of gingival inflammation and periodontal tissue destruction. www.indiandentalacademy.com
  • CLINICAL www.indiandentalacademy.com
  • Diagnosed by the clinicalevaluation of signs ofinflammation with orwithout periodontal tissuedestruction. www.indiandentalacademy.com
  • PERIODONTITIS – MEASUREDBY:A. Loss of connective tissue attachment.B Loss of radiographic bone loss. www.indiandentalacademy.com
  • Provides info on the pastperiodontal destruction, itsextent and severity www.indiandentalacademy.com
  • BUT DOES NOT PROVIDE INFOON :Patient’s susceptibilityDisease progression/ remissionPositive/ negative -response to therapy www.indiandentalacademy.com
  • GINGIVAL INFLAMMATION –Redness of gingivaSwellingGingival bleeding www.indiandentalacademy.com
  • STUDIES SAY that gingivalbleeding is a sensitive clinicalindicator of early gingivalinflammation !! www.indiandentalacademy.com
  • It is also a good indicator ofthe presence ofinflammatory lesion in theconnective tissue at the baseof the sulcus. www.indiandentalacademy.com
  • SEVERITY OF THE BLEEDINGincreases with an increase inthe size of inflammatoryinfiltrate. www.indiandentalacademy.com
  • RELATION to disease progressionis unclear. healthy sites may also evoke bleeding on probing. Sothe use of gingival bleedingcannot be totally depended upon. www.indiandentalacademy.com
  • INSTRUMENTS to measuregingival temp has beendeveloped.THERMAL PROBES – measureearly inflammatory changes inthe gingival tissues.EG : PERIOTEMP PROBE www.indiandentalacademy.com
  • IN PERIODONTITIS, widely useddiagnostic tool is the“periodontal probe” since increasedprobing depth and loss of clinicalattachment are exclusive for thisdisease. www.indiandentalacademy.com
  • www.indiandentalacademy.com
  • But use of periodontalprobes presents manyproblems in terms ofsensitivity andreproducibility ofmeasurements. www.indiandentalacademy.com
  • THE DISPARITY BETWEENMEASUREMENTSDepends on probing techniqueprobing forcesize of the probeangle of insertionprecision of probe calibration. www.indiandentalacademy.com
  • THE MAIN PROB IN REPRODUCIBILITYvariation in probing force.studies show - forces upto 50g isnecessary for detecting periodontalosseous defects! www.indiandentalacademy.com
  • NIDCR CRITERIA –FLORIDA PROBE SYSTEM –consists of a probe hand piece, digitalread out, foot switch, computerinterface and computer. tip is 0.4mmin diameter.Data is then transferred to thecomputer . www.indiandentalacademy.com
  • FLORIDA PROBE www.indiandentalacademy.com
  • Electronic probing systems-Interprobe system or Peri probesystem available.Other electronic probes -Fostermiller probe, Toronto automatedprobe, but not released yet. www.indiandentalacademy.com
  • RADIOLOGICAL www.indiandentalacademy.com
  • For detecting destruction ofAlveolar bone, Dental x-rays are mostcommonly used since they providevaluable info on interproximal boneloss. www.indiandentalacademy.com
  • More than 30% of the bone massat the alveolar crest should belost for a change in bone heightto be seen in dental radiographs. www.indiandentalacademy.com
  • DIGITAL RADIOGRAPHY – by the use of computerized images, which can be stored, manipulated and corrected for under and over exposures. advantage - diagnostic info can be enhanced. www.indiandentalacademy.com
  • SUBTRACTION RADIOGRAPHY – used in periodontal diagnosis. Relies on the conversion of serial radiographs into digital images. then they are superimposed to view on a video screen. www.indiandentalacademy.com
  • www.indiandentalacademy.com
  • COMPUTER – ASSISTEDDENSITOMETRIC IMAGEANALYSIS SYSTEM – a videocamera measures the lighttransmitted through a radiograph,signals from the cameraconverted into gray scale images.camera is fixed to an imageprocessor and a computer www.indiandentalacademy.com
  • MICROBIAL www.indiandentalacademy.com
  • MICROBIAL TESTS -can also be used to monitorperiodontal therapy directed atthe suppression or eradication ofperiodontopathic microorganisms www.indiandentalacademy.com
  • BACTERIAL CULTURING methods are used to detect the specific pathogens present in plaque, by using selective & non selective media. www.indiandentalacademy.com
  • DISADV Of the above method- strict sampling & transport conditions essential. Putative pathogens like Treponema species & B. forsythes are fastidious & difficult to culture. www.indiandentalacademy.com
  • Also requires sophisticatedequipments, experiencedpersonnel & time consuming,expensive !! www.indiandentalacademy.com
  • DARK FIELD OR PHASE CONTRASTMICROSCOPY – alternative method. Directly and rapidly assesses motility and morphology of bacteria in a plaque sample.NON MOTILE ORGANISMS CANNOT BEIDENTIFIED BY THIS METHOD. www.indiandentalacademy.com
  • PHASE CONTRASTMICROSCOPE www.indiandentalacademy.com
  • www.indiandentalacademy.com
  • IMMUNOLOGIC ASSAY –employs antibodies whichrecognizes specificbacterial antigens todetect target microorganisms. E.g.:Direct/Indirect IFA, ELISA,Membrane Assay, andLatex Agglutination. www.indiandentalacademy.com
  • ENZYMATIC METHODS – B. forsythus, P.gingivalis, Treponema denticola and Capnocytophaga- share a common enzymatic profile. Activity of this enzyme can be measured by using diagnostic kits like Perioscan. www.indiandentalacademy.com
  • OTHER DIAGNOSTIC ADVANCED AIDS ARE Nucleic acid probes, Restriction Endonuclease Analysis and Polymerase Chain Reaction. www.indiandentalacademy.com
  • ASSESSMENT OF THE HOSTRESPONSE –study of mediators, byimmunologic or biochemicalmethods. Mediators are eitherspecifically identified with theinfection or represent a lessspecific reaction www.indiandentalacademy.com
  • SAMPLE SOURCES – Saliva, GCF, Gingival Crevicular cells, blood serum, blood cells & urine. Urine samples show little promise except for its use in the differential diagnosis of tooth loss related to Hypophosphatasia in young children. www.indiandentalacademy.com
  • MORE THAN 40 COMPONENTS OF GCFHAS BEEN STUDIED WHICH CAN BEDIVIDED INTO 3 GROUPS –host derived enzymesinflammatory mediatorstissue breakdown products www.indiandentalacademy.com
  • SAMPLE COLLECTIONGCF-Method commonly used- Paperstrips.Strips are placed in the sulcus fora standard period of time untilthe paper gets saturated www.indiandentalacademy.com
  • Fluid volume collected can bequantified by using Periotron.This device measures the changein capacitance across the stripand this change is converted to adigital read out. www.indiandentalacademy.com
  • www.indiandentalacademy.com
  • SALIVA – EASE OF COLLECTION….contain bothlocally and systemically derivedmarkers of periodontitis..DIAGNOSTIC MARKERS in salivaproteins & enzymes of host origin,phenotypic markers, host cells,hormones, bacteria & bacterialproducts and ions. www.indiandentalacademy.com
