This led Periodontal instruments. six measures, traced three horizontal and . 8, 1984, pp. The maximum mean pocket depth at which evidence could be seen of instrumentation on the root surface (scratches or marks in remaining plaque or calculus) was 6.21mm with a SD of 1.32, with a range of 2 to 10mm. FIGURE 1. The relation-ship between the tip design, applied force, angulations and type of ultrasonic scaler has been studied and all of these variables have been shown to account for the adherent to the root surface and could be removed by much lighter instrumentation which did not damage the root surface to the same extent.3,4,23−26 One in vitro study24 showed that over 99% of the bacterial contaminants could be removed by light instrumentation alone, without the need for cementum removal by root planing. Ultrasonic instruments remove less root structure than hand instruments but leave behind a rougher surface. Based on current evidence in the literature, it is now known that endotoxin is a weakly adherent surface phenomenon and that sonic and ultrasonic (power-driven) instruments can be used to accomplish definitive root detoxification and maximal wound healing without overinstrumentation of root and without extensive cementum removal. This approach provides direct access to the root surface. The goal of instrumentation is to ensure a clean root surface which is biologically acceptable and is the prime requirement for a healthy periodontium. Polson AM, Frederick GT, Ladenheim S, et al. However, it was shown that microbial endotoxins are not strongly attached on the root surface and that periodontal health can be accomplished without the removal of cementum by scaling and root . Various dilutions of resuspended biofilm were . [ 11 ] "The Production of a Root Surface Smear Layer By Instrumentation and Its Removal By Citric Acid." Journal of Periodontology, vol. a type of instrumentation stroke used to remove residual calculus deposits, plaque biofilm, & byproducts from root surfaces exposed due to gingival recession or within deep periodontal pockets -A shaving stroke made w/moderate pressure w/ the cutting edge against the tooth cementum -stroke is slightly longer than a calculus removal stroke The type of instrumentation stroke used to facilitate tissue healing and refine the root surface is: A. The influence of scaler tip design on root surface roughness, tooth substance loss and patients' pain perception is investigated. College of Dental Sciences Rau. The presence and biologic activity of cementum-bound endotoxin. instrumentation from inside the root canal space are greater in the apex and along the canal walls than on the external root surface. 2. Root canal instrumentation includes both enlargement and shaping of the root canal system to allow effective disinfection by irrigants and medicaments. Objective The aim of the current study is to analyze the surface profiles of healthy and periodontal-treated roots. Root planing: instrumentation to remove the microbial flora on the root surface or lying free in the pocket, all flecks of calculus and all contaminated cementum and dentin.
443-6. dentin thickness relative to root surface. Gingivitis. In this in vitro study, root surface roughness was the same after both types of ultrasonic technology were used, though the piezoelectric device produced the least roughness when 200 g of pressure were applied. So the planed root surface area which was to be viewed under microscope was demarcated again by a extra fine-tip marker pen (tip diameter 0.5mm). Comparative evaluation of root surface after manual instrumentation with and without Er:YAG laser as an auxiliary therapy: in-vitro study Lizarelli, Rosane F. Z. Ferreira, Zulene A.

The surface roughness after instrumentation was evaluated with a profilometer and a scanning electron microscope. Conclusion: Roughness produced on the root surface after instrumentation is related to the surface area of ultrasonic tips and is inversely proportional. The surface roughness on root surface was increased in all groups after instrumentation. Debridement = scaling and root-planing plus. A comparison of root surface instrumentation using two piezoelectric ultrasonic scalers and a hand scaler in vivo. The root surface roughness produced by hand scaling and subsequent glycine powder air polishing (GPAP) was compared with that produced by ultrasonic scaling and subsequent GPAP. The greater stress distribution in the apical area could lead to the initiation of cracks and a root fracture can occur due to propagation of apical cracks. Gingivitis.

Results: Periodontal scaling and root planing performed with curettes, ultrasonic or combined instrumentation induced several morphological changes on the root surface. Moreover, the influence of operators' experience on treatment results is unclear. 4. This article was divided into the following parts: Part 1 Surface roughness and substance loss: an in vitro study, which involves intact extracted teeth sectioned and treated using a piezoelectric ultrasonic device (PM200 EMS Piezon, Switzerland) with a . Although a frequently used medical term, it wasn`t until 1994 that the word, debridement, first appeared in dental-hygiene literature in Irene Woodall`s textbook, Comprehensive Dental Hygiene Care. Advanced Techniques for Root Surface Debridement A.ppt. Histologic methods were used to determine the composition of the surfaces following instrumentation. Root Surface during Mechanical Instrumentation and Thermoplasticized Gutta-percha Obturation: An Ex Vivo Study Shivani Chauhan1, Atul Jain2, Abhinay Agarwal3, Rohit Sharma4, Madhurima Sharma5 AbstrAct Aim and objective: The study aimed to compare temperature increase on the external root surface in coronal third, middle third, and apical third Aleo JJ, De Renzis FA, Farber PA, Varboncoeur AP. However, the root surface roughness does not impede the success of mechanical subgingival instrumentation , although it would significantly increase soft and hard deposit accumulations. Choosing Instruments For General Dental Practice If you are going to provide effective periodontal treatment for your patients, then it is worthwhile investing in a suitable range of quality instruments. The goal of instrumentation is to ensure a clean root surface which is biologically acceptable and is the prime requirement for a healthy periodontium. 10 When piezoelectric, magnetostrictive, and curet instrumentation was compared, each removed approximately the same amount of calculus . the root surface got erased. Root specimens were obtained from extracted human teeth and randomly assigned to each group. Instrumentation of the exposed root surface to remove deposits is an integral part of this procedure. The instrumentation of the root surface was done by utilizing an EMS piezoelectric ultrasonic scaling unit as per the manufacturer's guidelines, in a standard mode with a water rate of 30 ml min-1 for 60 seconds for each sample. The production of a root surface smear layer by instrumentation and its removal by citric acid. This time, the boundaries of the instrumented root surface area were delineated coronally by the CEJ, apically by a line which extends 5mm apical to CEJ and proximally by two Surface roughness measurements (Ra and Rz) were taken with a profilometer before and after instrumentation. Instrumentation was continued until the root surface felt hard and smooth to an explorer tip.
I was honored to be part of the team responsible for Chapter 25, "Periodontal Debridement . Before D4346 was implemented, there was no code available to report therapeutic treatment of patients with generalized moderate to severe gingival inflammation with or without pseudo-pockets but exhibiting no bone loss. They are used for particular area of surface of the tooth B. The present study was designed to investigate the effectiveness of different ultrasonic instruments on the root surface. Root surface instrumentation with hand instruments is often difficult and time consuming, besides requiring a substantial amount of physical effort. Subgingival Instrumentation (root surface debridement / PMPR on root) I: Reinforce OH, risk factor control, behaviour change II: Subgingival instrumentation, hand or powered (sonic / ultrasonic), either alone or in combination III: Use of adjunctive systemic antimicrobials determined by Practitioner accredited for Level 2 and 3 care Parth Thakkar. This study measured root surface temperature changes when ultrasonic vibration, with and without irrigation, was applied to cemented endodontic posts. 5. root surface roughness after instrumentation is one of the most described alterations in the literature. Before D4346 was implemented, there was no code available to report therapeutic treatment of patients with generalized moderate to severe gingival inflammation with or without pseudo-pockets but exhibiting no bone loss. The combined manual/ultrasonic instrumentation (Group C) showed a peculiar morphology to the root surface with many differences when compared to the other treatments. Sickle Scalers Clinical Application Guide.
Hu-Friedy Mfg. Through this study, an attempt has been made to compare and evaluate the micro-topography of the root surface under scanning electron microscope, following instrumentation with curettes as well as ultrasonic perio mini-tip. The production of a root surface smear layer by instrumentation and its removal by citric acid. B, Angulation, the relation of the face of the blade to the tooth surface, in this case, is approximately 60 degrees. Average instrumentation time was 39 minutes for a maxillary posterior tooth, and 25 minutes for a mandibular posterior tooth. Sixty-five mandibular premolars were mounted in the acrylic tube with simulated periodontal ligaments and the apex was exposed. CLSM showed that the root surface treated by curette presented a smoother surface compare to those treated using the ultrasonic tip ( Figures 3A, ,B B). At present, root planing is no longer used to emphasize the deliberate removal of cementum, but to contribute to the removal of subgingival plaque. In general, the Universal curettes are . Neither hand nor mechanical instruments are superior in removing subgingival deposits. There is a significant difference between ultrasonic scalers and pumice, polishing paste and air powder, respectively (p < 0.05) ( Table 2 ). They have double cutting edge C. The main purpose of the present study was to evaluate the . Traditional nonsurgical periodontal therapy involves subgingival removal of hard and soft deposits on the root surface, along with maintenance of good oral hygiene. The samples were divided randomly into two groups. Only the lower third or half of the Cracey blade contacts the root surface during instrumentation. The aim of this study was to examine the surface roughness produced by root debridement during periodontal maintenance therapy. Methodology . The portion of tooth where calculus or necrotic cementum is found B. CEJ C. Exposed root surfaces D. Deep periodontal pocket # Gracey curettes have a characteristic feature that: A. The aim of the present study was to compare, histologically, the effects of hand instrumentation, ultrasonic instrumentation, and CO 2 lasers on the root surfaces of teeth treated in situ. Term scaling refers to the instrumentation of the crown and root surfaces of the teeth to remove plaque, calculus, and stains from these surfaces 1.Root planing is defined as a treatment procedure designed to remove cementum or surface dentin that is rough, impregnated with calculus, or contaminated . Root canal instrumentation has the potential to induce dentinal damage and to generate cracks on the apical surface which could ultimately lead to the development of vertical root fractures. One of the most important difficulty in the periodontal disease treatment resides in the impossibility of decontamination of roots just affected by the periodontal disease through mechanical tools. Semantic Scholar extracted view of "Profilometric and histological evaluation of the root surface after instrumentation in vitro with a fluorescence-controlled er: yag laser, hand instruments and an ultrasonic scaling device" by Jonas Alkimavicius et al. ( O Leary, 1977) Ninety teeth were randomly divided into three groups of 30 and subjected to three different root instrumentation: (1) manual instrumentation with a Gracey . Now let's test your periodontal instrumentation knowledge! Curette adapted to root surface. Teeth were assigned to In a recent study, Soros et al.
Introduction .
Periodontal curettes have one face, one or two cutting edges and a rounded back and rounded toe.
Background There is uncertainty regarding the benefits and risks of hand versus powered root surface instrumentation. Scaling is the process by which plaque and calculus are removed from both supragingval and subgingival tooth surfaces . Recommended. Kawashima H, Sato S, Kishida M, Ito K. J Periodontal Res, 42(1):90-95, 01 Feb 2007 Cited by: 41 articles | PMID: 17214645 Both statements are true. Periodontal instrumentation. Complex shank - bent in two planes (front to back and side to side) to facilitate instrumentation of . Fourteen patients with 35 single root teeth designated for extraction were recruited to the present study. Root canal instrumentation was initiated at the cervical third with 40/10 file followed by 35/.08, 25/.06 and 25/.04 files. posterior. The root surface characteristics after instrumentation were examined using scanning electron microscopy, and the amount of remaining calculus, roughness and loss of tooth substance were estimated using the remaining calculus index and roughness loss of . University of Malta.
To avoid the potential damage of the cementum surface done by sonic and US instruments and curettes, and looking after an effective treatment of the root surface, a sonic instrument covered by teflon was introduced in order to compare it with the standard instrumentation and with Per-io-Tor in extracted teeth. Recommended. If all the principles of instrumentation are followed, the chances of leaving deposits over the tooth/root surface are minimized. Surgical access is often necessary to facilitate mechanical instrumentation of the roots. never adapt the point or tip of the ultrasonic insert toward the tooth/root surface. In group1 (hand instrumentation), the mean surface roughness before and after intervention was 2.85±1.37 and 0.95±0.25, respectively which revealed root planning with a manual curette to be the most effective method for reduction of surface roughness. The periodontal curette is a type of hand-activated instrument used in dentistry and dental hygiene for the purpose of scaling and root planing. Dr.Jaffar Raza BDS. In this article. Objectives: To compare and evaluate the root surface roughness after using two polishing instruments for root planing.
Root surface roughness is one of the most described alterations in the literature after instrumentation, particularly in supportive periodontal therapy. Manual dental scaling results in the amorphous material without continuity solution due to the dental cut, denominated smear layer. Instrumentation of the exposed root surface to remove deposits is an integral part of this procedure.
