“…These errors originate from human negligence and can be avoided by the use of computers. The first controlled probing force probe that was capable of automated detection of the CEJ for determination of attachment levels and allowed for computerized data recording was presented by Jeffcoat et al (1986). The components of their probe include a pneumatic cylinder that pushes the core of a linear variable differential transducer, the force transducer, the accelerometer, and the probe tip forward until they attain the final position at the bottom of the pocket.…”

For decades, probing clinical pocket depth and attachment level have been recognized as the dentist's most important tools in diagnosing periodontal health and disease. They are physical methods to measure the distance from the bottom of a pocket to a reference line, usually the gingival margin or the cemento-enamel junction. Probing accuracy and precision are affected by factors like the design of the probe, probing force, probe position, pocket depth, or tissue inflammation. Recently, several new electronic periodontal probes have been developed. They feature high instrument precision, allowing for measurements to the nearest tenth of a millimeter. They control for probing force and permit data to be collected and stored electronically. The purpose of this review paper is to summarize various aspects of periodontal probing. First, the history of periodontal probes will be briefly recollected, and interesting and significant inventions of the past and the present emphasized. Then, the importance of the periodontal tissues relative to probe tip penetration will be reviewed, and the probing performance will be discussed. The paper will conclude with notes on selected statistical issues.

“…[10] In contrast, the Florida probe[11] is a third generation, commercially available, periodontal probe that combines controlled force application, automated measurement and computerized data collection and provides a means of recording attachment changes over time. When using the Florida probe, attachment levels are recorded relative to a fixed reference point, for example the occlusal surfaces of the teeth or a pre fabricated stent.…”

“…[1] Thus, the CEJ is a very important landmark for the periodontist, but various problems are faced while measuring CEJ, as difficulty in probing specially when it is subgingival[2] and it is difficult to detect CEJ if obscured by calculus or dental restorations. [3] Also, the three hard tissues found at the CEJ region are unpredictable and irregular on a single tooth and contra lateral teeth. [4]…”

Background:We face various problems while measuring the Clinical attachment level (CAL) from Cemento-enamel junction (CEJ). This study aims to record and compare the CEJ location measurements using a xed reference point (FRP) [Custom made stent] before and after ap elevation.Materials and Methods:A custom made stent and UNC-15 probe were used. Recording of CEJ location was made using a UNC-15 (Hu-Friedy) probe, before (close CEJ) and after (Open CEJ) the reflection of the flap from the lower edge of the stent in those subjects who were indicated for flap surgery, at baseline.Results:We used statistical analysis involving intra-group comparison done by Paired-‘t’ test. The close and the open CEJ measurements demonstrated a, statistically, non-significant difference. The equi-measurements of close and open CEJ numerical data were remarkably lower than the under and overestimation of measurements. Thus, despite certain disadvantages of stent, the FRP provides a simple solution for CAL measurement.Conclusion:The results of this study confirms the objective of the study and strongly suggests that CAL measurements done without FRP is subjected to great variation and the diagnostic and prognostic interpretation of CAL should be viewed seriously in periodontics.

“…The amelocemental junction, although an important clinical and radiographic landmark (19,20), is not always readily recognizable clinically, even with the additional diagnostic aid of tactile change in the contour of the tooth surface. This potential source of error in both clinical and epidemiologic studies is seldom addressed (21,22). In this context, two other assumptions should be queried-namely that when the cervical region is exposed, any change in hard tissue is limited to the root surface and that the enamel at the amelocemental junction is constant over time and therefore an appropriate landmark for measurements of loss of attachment.…”

The buccal surfaces of premolar teeth are common sites of gingival recession, generally attributed to overzealous oral hygiene. Scanning electron microscopy (SEM) of replicas made from dental impressions was applied to document the micromorphology of the buccocervical region of all premolar teeth in 27 dentally healthy, young adults. The SEM observations were correlated with clinical examination. Of the 216 sites, one-third, predominantly the maxillary first premolars, had gingival recession, but fewer than 50% were clinically discernible. The exposed roots were devoid of cementum, and the dentinal surface was smear-like or dotted with tubular apertures from which droplets of fluid extruded. SEM of replicas of gingiva, recorded as clinically healthy, frequently showed signs of inflammation: fluid exudate and distortion of gingival contour by swelling. The cervical enamel of healthy and affected sites showed characteristic periodic fissure-like cracks, probably enamel tufts. The high frequency of subclinical gingival recession, exposed cervical dentin, and gingival inflammation in dentally healthy young adults, in the absence of abrasion of hard or soft tissues, indicates the need to review conventional concepts of initiation of buccal recession and root exposure.
