Figure 5. Where recession is present, the addition of the recession and pocket measurements gives the attachment loss (AL) measurement for that particular tooth surface. Consequently, removing all elements that may provoke inflammation and prevent the re-establishment of periodontal health from the tooth surface remains our primary goal in periodontal therapy.

While the American Academy of Periodontology and the European Federation of Periodontology published an improved classification of periodontal diseasesin 2018, the clinical application of the new classification as a guide to the delivery of care for patients in need of periodontal treatment is often unclear. Research suggests that the amount of residual calculus and subgingival plaque is the same irrespective of whether a procedure has been performed using a hand instrument or an ultrasonic device.19 However, healing response to nonsurgical therapy for molar furcation sites is impaired relative to non-molar sites and molar flat surfaces.20 Molar furcations may also show a higher frequency of continued attachment loss following initial therapy.20, Removal of plaque virulence factors such as bacterial endotoxin is desirable but may be independent of complete calculus removal. J Periodontol. 1990 Jan;61(1):16-20. doi: 10.1902/jop.1990.61.1.16. Of noted importance is the inflammatory status of the tissues. 19. The learning curve to use the DetecTar is quick and easily achieved. While bacterial plaque is the proximate cause of periodontal degeneration, once subgingival calculus has formed, it must be completely removed from the root for SRP to be a successful treatment for periodontal diseases. Many of the modifications in hand instrument design are now being incorporated into ultrasonics. J Clin Periodontol. Bleeding on probing (BOP) can also be noted at this time, as it is often an early sign of active inflammation at that site. Caton JG, Armitage G, Berglundh T, et al. In humans, the severity of periodontitis is based on a number of findings, including tooth mobility, BOP, AL, furcation involvement, purulent discharges from pockets, and tooth pain associated with percussion or thermal sensitivity testing. The .gov means its official. Three experienced clinicians performed blind controlled in vitro evaluations of 150 extracted periodontally involved teeth. The ability to detect subgingival calculus is paramount to the successful treatment of periodontal disease. Overall, both surgical and nonsurgical approaches have been shown to result in similar mean improvements of clinical scores.19 Surgery may be more strongly indicated at deep pockets, where surgical therapy has been associated with greater pocket depth reduction and clinical attachment gain.25 Referral to a periodontist to determine if surgical therapy is necessary may be recommended if pockets >5 mm persist after instrumentation. Perform exploration techniques to detect residual calculus deposits. The trail is open year-round and is beautiful to visit anytime. The effectiveness of subgingival scaling and root planning. I. Clinical 11. 3. Bacteria play a crucial role in disease etiology and their removal represents the focus of much of the strategy for treatment of periodontal diseases. Is the Use of Antimicrobial Photodynamic Therapy or Systemic Antibiotics More Effective in Improving Periodontal Health When Used in Conjunction with Localised Non-Surgical Periodontal Therapy? M3 = Severe mobility > 1 mm or intruded into socket or can be extruded out of socket, 1 = Lesion in enamel, cementum The instrument tip responds by vibrating at a frequency between 2,500 and 16,000 Hz.15 Ultrasonic instruments are more commonly used and work on the principle of conversion of electrical to mechanical energy, resulting in high frequencies of vibration, disrupting plaque and calculus deposits. Comparative effectiveness of ultrasonic and hand scaling for the removal of subgingival plaque and calculus. 5. 1995;66(1):23-29. Useful inclusions: Chair-side developer with rapid developer/fixer, ideally radiographic viewing box. 2nd ed. However, the ability to clinically detect initial and residual subgingival calculus using subjective tactile sense with a probe or explorer has come into question many times. Thus, residual and fractured subgingival calculus remaining after SRP is undoubtedly a major cause of inadequate treatment of periodontitis.5. The effect of plaque control and root debridement in molar teeth. Paris, France: Quintessence International; 2007. 3 = Penetration further into dentine, close to pulp Dental X-ray equipment: non-screen dental films, film clips for handling, and envelopes for radiographic storage or you can digitalise radiographs for storage on computer hard drive. Single versus repeated instrumentation. In fact, the removal of all subgingival plaque and calculus is unlikely to occur when mean probing depths is = 3.73 mm.13. There is an increasing uptake of digital radiography in human dentistry also. Unfortunately, the removal of all calculus from the root surface can be very difficult if the teeth have more than a few millimeters of periodontal pocketing. Grading also allows all of the practice staff to be on the "same page" in recognizing the severity of the disease. The studies demonstrated a direct correlation between increasing probing depth and increasing percentage of root surfaces exhibiting residual calculus after treatment. Unauthorized use of these marks is strictly prohibited. A study conducted at McGill University Dental Research Centre, Montreal, Quebec, by Mervyn Gornitsky, DDS, demonstrated the efficacy of the DetecTar. Some of the key features of these instrument types are addressed in Table 1. Lee N Sheldon, DMD, has provided comprehensive implant, periodontic, and full-mouth rehabilitation dental services for more than 30 years in his private practice in Melbourne, Florida.

Clipboard, Search History, and several other advanced features are temporarily unavailable. 1979;14(3):239-243. The results showed not only that the DetecTar was ~91% efficient at detecting calculus; it also standardized the quality of detection from one operator to the other, which differs from conventional probing where results vary considerably depending on the expertise of the clinician. The first marking visible above the gingival margin is the probing depth measurement. 2022 Oct 20;10(10):195. doi: 10.3390/dj10100195. In daily clinical practice, the DetecTar can be used in several ways: The DetecTar probe was developed to evaluate the surface of roots and to detect differences between the calculus and the tooth surface. Pocket depth and location, access, and visibility are all highly important for reproducibility of probing measurements.4 Large deviations in probing depth are more commonly noted at deep pocket sites and, while infrequent, are clinically significant and may lead to altered decision making in diagnosis and treatment. Association between socioeconomic contextual factor, dental care It is well established that plaque bacteria play a key etiologic role in development of gingivitis5 and in the pathogenesis of periodontitis.6 Subgingival plaque bacteria have been associated with periodontal disease progression, as measured by alveolar bone loss.7. Repeated unsuccessful closed SRP does not represent advanced therapy. Usually record 6 probing depths for large and important teeth such as canine, carnassial teeth, and molar teeth. Performing any level of periodontal therapy and not reevaluating the results and informing the patient of the availability of any necessary additional treatment or maintenance care, when appropriate, constitutes inadequate care.

Vaia E, Bozzini V, Nicol M, Riccitiello F. J Clin Periodontol. The advent of an objective method of detecting calculus provides us with a new dimension in periodontal therapy. PDF Dental Hygiene Diagnosis and Care Planning - LWW I. Periodontal Treatments Defined - Decisions in Dentistry Recent developments in electronic probing have focused on ease of use and ergonomics (eg, Dolphin handpiece, Florida Probe Corporation). Perhaps the most widely used hand instrument is the Gracey curette. One of the goals of periodontal probing is the detection of etiological factors such as calculus, defective margins, root erosion, and pocket dimensions.12 Depending on the type of probe used, the probing forces, and the level of inflammation of the periodontal tissues, the accuracy of probing can be severely affected.

Furcation areas exhibit a complex and varying anatomy, and furcation entrances are often a dimension smaller than traditional curette tips.24 Access is consequently a key issue in providing effective treatment and has led to modifications in instrument design over time, particularly the development of smaller ultrasonic tips which may be favored as instruments of choice for furcation sites.19. . This results in the reduction of root surface damage from nonspecific scaling and root planning and in a predictable end point for treatment. The introduction of minimally invasive surgical techniques combined with high-resolution dental videoscopes, when used to treat periodontitis, resulted in the discovery of root surface features not previously reported, i.e., microgrooves [1,2] and microislands of the calculus [].The microislands are embedded in cementum and represent residual deposits of calculus following . After an initial debridement with ultrasonics to remove maximum plaque and hard deposits, the DetecTar can be used to identify residual subgingival calculus, thus allowing the practitioner to focus treatment on specific areas.

Analysis and interpretation of these studies is complicated by factors including differences in experimental design, treatment protocols, and methods of data collection. Handles may be resin covered for a more comfortable grip (eg, elliptically shaped cushion grips) and may be textured for improved rotational control. A conventional probe and a DetecTar probe. A computer-processed algorithm determines whether the probe is in contact with dental calculus and activates both an auditory and light signal to notify the clinician of the presence of the calculus (Figures 4 and 5). 2 = Moderate calculus covering 1/3 to 2/3 buccal tooth surface with minimal subgingival deposit Probing pressure, a highly undervalued unit of measure in periodontal probing: a systematic review on its effect on probing pocket depth. To facilitate the process, machined sharpening tools have been developed. Lubrication (eg, orange solvent) should be used before sharpening to decrease clogging of the abrasive surface from metal particles. FOIA Severely advanced periodontitis.
