Improved plaque removal efficacy with a new manual toothbrush.

J Contemp Dent Pract. 2008;9(4):1-8

Authors: Biesbrock AR, Bartizek RD, Walters PA

AIM: To compare the safety and efficacy of two manual toothbrushes, Oral-B Exceed and Asian Colgate 360 masculine, in removing plaque. METHODS AND MATERIALS: The study used an examiner-blind, two-treatment, randomized, four-period (visits) crossover design. At the first visit, subjects received a baseline plaque examination; plaque was scored using the Rustogi et al. Modified Navy Plaque Index (RMNPI) and the Turesky et al. Modified Quigley-Hein Plaque Index (TQHPI). Subjects used their assigned toothbrush for one minute. Post-brushing plaque was assessed. The following three visits were separated by an interval of two to six days. At each visit, subjects were assigned brushes according to their treatment sequence and plaque was scored per the first visit. RESULTS: Forty-eight subjects were enrolled in the study; 47 were included in the analysis. Both brushes were found to be safe and both significantly reduced plaque after a single brushing. The Oral-B Exceed was significantly (p<0.001) better than the Asian Colgate 360 masculine at removing whole mouth plaque (18.1% using TQHPI; 9% using RMNPI). The Oral-B Exceed was also significantly better at removing marginal (p=0.001) and approximal (p=0.022) plaque. CONCLUSION: The Oral-B Exceed brush removed significantly more whole mouth, approximal, and gingival margin plaque than the Asian Colgate 360 masculine in a four-period crossover clinical comparison.

Clinical performance of IPS-Empress 2 ceramic crowns inserted by general dental practitioners.

J Contemp Dent Pract. 2008;9(4):9-16

Authors: Mansour YF, Al-Omiri MK, Khader YS, Al-Wahadni A

AIM: The aim of this study was to evaluate the clinical performance of IPS-Empress 2(R) all-ceramic crowns placed by general dental practitioners. METHODS AND MATERIALS: Eighty-two IPS-Empress 2 crowns placed in 64 patients (27 females and 37 males) were evaluated. These crowns had been in place for 15.2 to 57.2 months (mean 25.3 months, SD=9.3). Survival analysis was conducted using the Kaplan-Meier method. RESULTS: Of the 82 crowns 93.9% were rated satisfactory. In terms of the integrity of the restorations, fracture was observed in three crowns and two showed a crack upon transillumination. Five crowns were rated unsatisfactory for color match; one for marginal adaptation; and none for discoloration, secondary caries, or sensitivity. CONCLUSIONS: IPS-Empress 2(R) is a suitable material to fabricate all-ceramic crowns; when these all-ceramic crowns were inserted by general dental practitioners, they functioned satisfactorily with low failure rates during an observation period ranging between 15.2 to 57.2 months.

A Comparative in vitro study of the load at fracture of all-ceramic crowns with various thicknesses of In-Ceram core.

J Contemp Dent Pract. 2008;9(4):17-25

Authors: Gokce S, Celik-Bagci E, Turkyilmaz I

AIM: The aim of this study was to investigate the influence of three different thicknesses of In-Ceram core on the load at fracture of all-ceramic crowns. METHODS AND MATERIALS: Thirty standardized crown-shaped nickel-chromium alloy dies were fabricated using a milling machine. Twenty dies were prepared with a 1 mm shoulder for Groups A and B. The only difference in the ten dies used for Group C was a smaller 0.5 mm lingual shoulder. The thicknesses of In-Ceram were 0.5 mm, 1.5 mm, and 0.75 mm for Groups A, B, and C. All all-ceramic crowns were fabricated in accordance with the manufacturer's instructions. After cementation of the crowns, their fracture resistance was tested with a universal testing machine. The load was directed to a point located 3 mm from the lingual aspect of the incisal edge at 30 degrees to the long axis of each specimen until catastrophic failure occurred. RESULTS: The mean loads at fracture for Groups A, B, and C were 1117+/-388 N, 2083+/-385 N, and 1439+/-368 N, respectively. No statistically significant difference in load at fracture between Groups A and C was found (p>0.05). However, the differences were statistically significant between Groups A and B (p<0.001) and Groups B and C (p<0.001). CONCLUSION: Under the guidelines of this study, increasing the thickness of the In-Ceram core increased the fracture resistance of the all-ceramic crowns. CLINICAL SIGNIFICANCE: The sufficient thickness of the In-Ceram core of all-ceramic crowns is an important factor in fracture resistance. Therefore, dental practitioners should be careful in patient selection; if the horizontal overlap of a tooth to be restored is too limited, then all-ceramic crowns may not be a feasible option.

One year clinical evaluation of two different types of composite resins in posterior teeth.

J Contemp Dent Pract. 2008;9(4):26-33

Authors: Gianordoli Neto R, Santiago SL, Mendonca JS, Passos VF, Lauris JR, Navarro MF

AIM: The aim of this study was to assess the clinical performance of two adhesive restorative systems (Single Bond/Filtek P-60 and Single Bond/Filtek Z-250) in posterior teeth using a modified United States Public Health Service (USPHS) system. METHODS AND MATERIALS: A total of 70 restorations were placed in molars and premolars in 30 patients (14 females and 16 males; 18-40 years) by one operator. All restorations were directly evaluated by two examiners at baseline, six months, and 12 months using the following modified USPHS rating criteria: marginal integrity, marginal discoloration, surface texture, contour, postoperative sensitivity, and recurrent caries. RESULTS: At six and 12 months all restorations were available for evaluation of marginal discoloration, surface texture, contour, postoperative sensitivity, and recurrent caries that remained with 100% Alpha-ratings at recalls for both restorative systems. Marginal integrity for P-60 was scored as 94.3% and 91.4% Alpha at six and 12 months, respectively, and rates for Z-250 were 100% and 97.1% Alpha at six and 12 months, respectively. Statistical analysis was completed with Fisher's exact and McNemar Chi-square tests at a significance level of 5% (P<0.05). CONCLUSION: All restorations were clinically satisfactory and no significant differences were found among them. CLINICAL SIGNIFICANCE: Posterior resin composite restorations placed under appropriate conditions provide a satisfactory clinical performance.

Resin Bonding to Root Canal Dentin: Effect of the Application of an Experimental Hydrophobic Resin Coating after an All-in-one Adhesive.

J Contemp Dent Pract. 2008;9(4):34-42

Authors: Lombardo GH, Souza RO, Michida SM, de Melo RM, Bottino MA, Valandro LF

AIM: Based on the hypothesis the application of a low-viscosity hydrophobic resin coating improves the bond of all-in-one adhesive, the purpose of the study was to evaluate the bond strength of four adhesive systems to bovine root dentin using the push-out test method. METHODS AND MATERIALS: The root canals of 32 bovine roots (16 mm) were prepared to a length of 12 mm using a FRC Postec Plus preparation drill. The specimens were allocated into four groups according to the adhesive system used: (Group 1) All-in-one Xeno III; (Group 2) All-in-one Xeno III+ScotchBond Multi-Purpose Plus Adhesive; (Group 3) Simplified Etch & Rinse One Step Plus; and (Group 4) Multi-Bottle Etch & Rinse All-Bond 2. A fiber-reinforced composite retention post was reproduced using an additional silicon impression and fabricated with DuoLink resin cement. The root specimens were treated with the selected adhesive systems, and the resin posts were luted in the canals with DuoLink resin cement. Each root specimen was cross sectioned into four samples (+/-1.8 mm in thickness), and the post sections were pushed-out to determine the bond strength to dentin. RESULTS: Group 2 (2.9+/-1.2) was statistically higher than Group 1 (1.1+/-0.5) and Group 3 (1.1+/-0.5). Groups 1 and 3 showed no statistically significant difference while Group 4 (2.0+/-0.7) presented similar values (p>0.05) to Groups 1, 2, and 3 [(one-way analysis of variance (ANOVA)] and Tukey test, a=0.05). CONCLUSION: The hypothesis was accepted since the application of the additional layer of a low-viscosity bonding resin improved the bond of the all-in-one adhesive. Further studies must be conducted to evaluate the long-term bond.

Composite resin microhardness: the influence of light curing method, composite shade, and depth of cure.

J Contemp Dent Pract. 2008;9(4):43-50

Authors: de Araujo CS, Schein MT, Zanchi CH, Rodrigues SA, Demarco FF

AIM: The aim of this study was to investigate the influence of light curing method, composite shade, and depth of cure on composite microhardness. METHODS AND MATERIALS: Forty-eight specimens with 4 mm of depth were prepared with a hybrid composite (Filtek Z-100, 3M ESPE); 24 with shade A1 and the remaining with shade C2. For each shade, two light curing units (LCUs) were used: a quartz-tungsten-halogen (QTH) LCU (Optilight Plus - Gnatus) and a light emitting diode (LED) LCU (LEC 470 II - MM Optics). The LED LCU was tested using two exposure times (LED 40 seconds and LED 60 seconds). After 24-hour storage, three indentations were made at mm depth intervals using a Knoop indenter. Data were submitted to three-way analysis of variance (ANOVA) and Tukey's test (p<0.05). RESULTS: The three factors tested (light curing method, shade, and depth) had a significant influence on the composite microhardness (p<0.05). All groups presented similar hardness values in the first mm, except for composite shade C2 cured with LED for 40 seconds. The hardness decreased with depth, especially for shade C2 for 40 seconds. Increasing light-curing time with LED produced hardness values similar to the QTH. CONCLUSIONS: The light curing method including variations of time, the depth of cure, and the composite shade influence the composite microhardness. CLINICAL SIGNIFICANCE: Clinicians should avoid thicker increments when working with composite restorations. Extended light-curing time might be indicated depending on the composite shade and on the light-curing device.

Relative impact of patient characteristics and radiographic variables on the difficulty of removing impacted mandibular third molars.

J Contemp Dent Pract. 2008;9(4):51-8

Authors: Akadiri OA, Obiechina AE, Arotiba JT, Fasola AO

AIM: The aim of this study was to assess the relative contributions of patient characteristics and radiographic variables to the difficulty of extraction of impacted mandibular third molars in a Nigerian population. METHODS AND MATERIALS: Seventy-nine consecutive patients undergoing mandibular third molar extractions were recruited for this prospective cohort study. Specific patient characteristics and radiographic variables were recorded. All extractions were performed under local anesthesia by the same oral surgeon, and the surgical difficulty was assessed based on the duration of surgery. RESULTS: Body weight (BW) (P=0.009) and body surface area (BSA) (P=0.004) were the significant patient characteristics while tooth impaction depth (P=0.002), number of roots (P=0.035), and tooth angulation (P=0.003) were the significant radiographic variables associated with surgical difficulty using a univariate analysis. A multiple linear regression model was constructed with these variables using surgical difficulty as the dependent variable. Radiographic factors were found to be the more important determinants of surgical difficulty with the depth of impaction (P=0.038) being the singular most important factor. CONCLUSION: Although the difficulty of surgical removal of impacted lower third molars is dependent on BW, BSA, impaction depth, tooth angulation, and the number of roots, radiographic variables were of greater importance with impaction depth being the most important single factor.

Effect of storage time on the accuracy of casts made from different irreversible hydrocolloids.

J Contemp Dent Pract. 2008;9(4):59-66

Authors: Sedda M, Casarotto A, Raustia A, Borracchini A

AIM: Several new irreversible hydrocolloid formulations have recently become available with claims of an improved dimensional stability by the manufacturers. The aim of this study was to evaluate the accuracy of casts made from alginate impression materials poured immediately and after specific storage periods. METHODS AND MATERIALS: Five alginates were tested: CA 37 (Cavex); Jeltrate (Dentsply Caulk); Jeltrate Plus (Dentsply Latin America); Hydrogum 5 (Zhermack); and Alginoplast (Heraeus Kulzer). A master model was mounted on a special device and used to obtain the impressions. These impressions were stored at 23 degrees C and 100% relative humidity, then poured with gypsum immediately, and again after 24, 72 and 120 hours. The casts were measured and the data were analyzed by one way analysis of variance (ANOVA) and Tukey test at p<0.05. RESULTS: The dimensional stability of the alginate impressions was both material and time dependent (p<0.05). After 24 hours of storage, only Alginoplast and Hydrogum 5 comply with the master model (p>0.05). After 72 and 120 hours, only Hydrogum 5 was dimensionally stable (p>0.05). CONCLUSION: The dimensional stability of the alginate impressions is influenced by the selected material and the storage time. CLINICAL SIGNIFICANCE: Alginate impressions should generally be poured immediately. However, some new types of alginate may have the pouring delayed.

Evaluation of Tissue Reaction to Some Denture-base Materials: An Animal Study.

J Contemp Dent Pract. 2008;9(4):67-74

Authors: Ebadian B, Razavi M, Soleimanpour S, Mosharraf R

AIM: Controversy continues regarding the biocompatibility of denture base materials. One method to evaluate the biocompatibility of materials is in an animal study. Using dogs as subjects, the purpose of this study was to evaluate the vestibular tissue reaction to cobalt chromium (Co-Cr), heat cure acrylic resin, and acrylic resin mixed with aluminum oxide (Al2O3) compared with a control group using the histopathologic method. METHODS AND MATERIALS: Twelve disk shape samples (2 mm x 8 mm) in four groups of Co-Cr, acrylic resin, acrylic resin mixed with a 20% weight ratio of Al2O3, and a control group (Teflon) were fabricated. In one stage surgery two samples of each material (8 samples) was implanted in the buccal vestibule of each dog (n=6), subcutaneously. At 45 and 90-day intervals, half of the samples were excised along with peripheral tissue to assess the presence of inflammation by grading on a scale from 0 to 3 and the presence of a fibrotic capsule using histological observations. Data were analyzed using the Kruskal-Wallis, Mann-Whitney, and Tau b Kendal tests. RESULTS: Tissue reaction between Co-Cr and the control group was significant (P=0.02), but it was not significant between other groups. There was no significant difference between the 45 and 90-day post-insertion samples. The formation of fibrotic capsule groups was significant (P=0.01). It was significant between the Co-Cr and acrylic resin groups (P=0.01) and the acrylic resin and control groups (P=0.01). CONCLUSION: The Co-Cr group was more toxic than the other groups. The inflammation increased during time. The inflammation in two acrylic groups was greater than the control and less than the Co-Cr group. The formation of fibrotic capsule, except in the acrylic resin with Al2O3 group, increased over time. CLINICAL SIGNIFICANCE: Co-Cr alloys are toxic and can produce damage to living tissue. Heat cure acrylic resin materials have less toxicity, and their use is safer than Co-Cr alloys.

Ozone therapy in medicine and dentistry.

J Contemp Dent Pract. 2008;9(4):75-84

Authors: Nogales CG, Ferrari PH, Kantorovich EO, Lage-Marques JL

AIM: The purpose of this review is to present the potential for the incorporation of ozone therapy into the practice of dentistry. BACKGROUND: Ozone gas has a high oxidation potential and is 1.5 times greater than chloride when used as an antimicrobial agent against bacteria, viruses, fungi, and protozoa. It also has the capacity to stimulate blood circulation and the immune response. Such features justify the current interest in its application in medicine and dentistry and have been indicated for the treatment of 260 different pathologies. It can be used for the treatment of alveolitis as a replacement for antibiotic therapy, as a mouthwash for reducing the oral microflora, as well as the adherence of microorganisms to tooth surfaces. Ozone has been shown to stimulate remineralization of recent caries-affected teeth after a period of about six to eight weeks. CONCLUSION: The future of ozone therapy must focus on the establishment of safe and well-defined parameters in accordance with randomized, controlled trials to determine the precise indications and guidelines in order to treat various medical and dental pathologies. Scientific support, as suggested by demonstrated studies, for ozone therapy presents a potential for an atraumatic, biologically-based treatment for conditions encountered in dental practice.

Clinical and radiological findings related to tuberous sclerosis complex: a case report.

J Contemp Dent Pract. 2008;9(4):85-91

Authors: Gupta S, Bhowate R, Degwekar SS

AIM: The aim of this report is to present the intraoral and extraoral clinical features of a young female patient with tuberous sclerosis complex (TSC) who exhibited multiple hamartomas of various organ systems including a fibromatous growth on the gingiva. BACKGROUND: TSC is a rare neurocutaneous syndrome exhibiting multiple hamartomatous proliferations that may involve multiple organs such as the brain, kidney, heart, eyes, lungs and skin. Oral manifestations such as enamel pitting and fibromatous growth of the gingiva are commonly seen in patients with TSC. REPORT: A 16-year-old female patient presented with a painless interdental gingival growth in the maxillary left incisor and canine region that bled occasionally. Associated findings were adenoma sebaceum (angiofibromas) on the face, a Shagreen patch on the lumbosacral region, ash leaf spots on the trunk, and subangual fibromas (Koenen's tumor) on the nails of fingers and toes. The final diagnosis of TSC was made on the basis of the clinical findings of the skin, computerized tomography (CT) findings of the brain and kidney, ultrasonographic findings of kidney, and a histopathologic evaluation of the gingival growth which met the major and minor criteria required for a diagnosis of TSC. SUMMARY: This case report is a good example of the complex nature of patients with TSC. The diagnosis and management of these patients varies depending on the specific presentation of the disease. Dentists need to be mindful of the systemic issues as well as oral conditions related to this disease. Dental practitioners are advised to work closely with the patient's physician during treatment.

Authors: Sholapurkar A, Joseph RM, Varghese JM, Neelagiri K, Acharya SR, Hegde V, Pai KM, Bhat M

AIM: This clinical report describes the oral rehabilitation of a young female patient diagnosed with the hypocalcified, autosomal recessive type of Amelogenesis imperfecta (AI). A brief discussion on diagnosis of AI is also included. BACKGROUND: AI has been defined as a group of hereditary enamel defects not associated with evidence of systemic disease. It can be characterized by enamel hypoplasia and/or hypomaturation or hypocalcification of the existing teeth. Restoration for patients with this condition should be oriented toward the functional and esthetic rehabilitation and the protection of these teeth. REPORT: A 31-year-old female patient presented with concerns including extreme sensitivity; dissatisfaction with size, shape, and shade of teeth; and poor masticatory efficiency. She was very conscious about the appearance of her teeth and reported that her primary dentition was affected in the same manner. The specific objectives of this treatment were to eliminate tooth sensitivity, enhance esthetics, and restore masticatory function. Treatment included crown lengthening procedures and placement of anterior and posterior metal-ceramic crowns. A 12-month follow-up with clinical and radiographic examinations revealed no evidence of any untoward effects of the treatment on the restored teeth or their supporting structures. SUMMARY: Management of a patient with AI is a challenge for the clinician. The treatment options vary considerably depending on several factors such as the age of the patient, socio-economic status, periodontal condition, loss of tooth structure, severity of the disorder, and, most importantly, the patient's cooperation. The clinician has to consider the long-term prognosis of the treatment outcome. This clinical report describes the fabrication of metal ceramic and all metal crowns for the restoration of severely worn teeth in a patient with AI which requires meticulous maintenance of oral hygiene and patient co-operation.

Localized Alveolar Ridge Augmentation Using a Two-step Approach with Different Soft Tissue Grafts: A Clinical Report.

J Contemp Dent Pract. 2008;9(4):99-106

Authors: Walter C, Büttel L, Weiger R

AIM: The purpose of this report is to present the use of different soft tissue grafting procedures for surgical ridge augmentation. BACKGROUND: Multiple augmentative procedures may be indicated for the esthetic reconstruction of edentulous alveolar ridge deformities due to unpredictable shrinkage of augmented tissues. REPORT: A 38-year-old woman with a moderate Class III alveolar ridge defect received periodontal plastic surgery treatment using a combined onlay-interpositional graft procedure and a subepithelial connective tissue graft. SUMMARY: This case illustrates the aesthetic reconstruction of a moderate alveolar ridge defect using a two-step approach. CLINICAL SIGNIFICANCE: Using different soft tissue grafting procedures might be helpful in planning and treating moderate alveolar ridge defects. The time for remodelling of the augmented tissues needs to be respected before the final prosthesis is placed.

Endodontic-periodontic Bifurcation Lesions: A Novel Treatment Option.

J Contemp Dent Pract. 2008;9(4):107-14

Authors: Lin S, Tillinger G, Zuckerman O

AIM: The purpose of this preliminary clinical report is to suggest a novel treatment modality for periodontal bifurcation lesions of endodontic origin. METHODS AND MATERIALS: The study consisted of 11 consecutive patients who presented with periodontal bifurcation lesions of endodontic origin (endo-perio lesions). All patients were followed-up for at least 12 months. Treatment included calcium hydroxide with iodine-potassium iodide placed in the root canals for 90 days followed by canal sealing with gutta-percha and cement during a second stage. Dentin bonding was used to seal the furcation floor to prevent the ingress of bacteria and their by-products to the furcation root area through the accessory canals. RESULTS: A radiographic examination showed complete healing of the periradicular lesion in all patients. Probing periodontal pocket depths decreased to 2 to 4 mm (mean 3.5 mm), and resolution of the furcation involvement was observed in post-operative clinical evaluations. CONCLUSIONS: The suggested treatment of endo-perio lesions may result in complete healing. Further studies are warranted. CLINICAL SIGNIFICANCE: This treatment method improves both the disinfection of the bifurcation area and the healing process in endodontically treated teeth considered to be hopeless.

Implementation of a Digital Radiographic Image Acquisition and Retrieval System (DRIARS) Using a Wireless Network in an Orthodontic Department.

J Contemp Dent Pract. 2008;9(4):115-23

Authors: Mupparapu M, Binder RE, Cummins JM, Feldman CA, Cappelli MA, Matheson PB

AIM: The objective of this report is to describe the implementation and pilot-test of an integrated wireless local area network (WLAN) system that incorporated the Planmeca Promax(R) CCD based digital panoramic/cephalometric x-ray system, Dolphin(R) software, and multiple remote user units to increase the efficiency of data management by the residents in the Department of Orthodontics. BACKGROUND: The Department of Orthodontics of the New Jersey Dental School (NJDS) acquired the Dolphin(R) cephalometric analysis software and the Planmeca Promax(R) digital panoramic/cephalometric x-ray units on separate occasions. Dolphin has been in use for many years at this institution, the current version being 10, and the Promax was acquired in the Fall of 2002. The digital panoramic and cephalometric radiographs were acquired and stored separately in the Planmeca's Dimaxis database. REPORT: During the incorporation of the WLAN, there was an opportunity to research and install the best available security system for the WLAN so it could be a network model for the other departments within the dental school and perhaps other dental schools around the nation. SUMMARY: Digital radiographs, once obtained, can be stored locally or transmitted securely to remote locations via a local area network. This article describes the selection criteria and methodology that would optimize the transmission and retrieval of such images instantaneously on demand at chair side locations. This will not only save significant clinical time but will enhance the productivity of the clinic in the long run.

Statin use is associated with fewer periodontal lesions: a retrospective study

BMC Oral Health - Latest articles — Thu, 15 May 2008 04:00:00 +0100

Background Inflammatory processes are considered to participate in the development of cardiovascular disease (CVD). Statins have been used successfully in the prevention and treatment of coronary heart disease. Chronic periodontitis has been suggested to contribute to CVD. The aim of this study was to examine the association of statin use and clinical markers of chronic periodontitis. Methods Periodontal probing pocket depth (PPD) values were collected from dental records of 100 consecutive adult patients referred to a university dental clinic for treatment of advanced chronic periodontitis. A novel index, Periodontal Inflammatory Burden Index (PIBI), was derived from the PPD values to estimate systemic effects of periodontitis. Results Periodontitis patients taking statins had a 37% lower number of pathological periodontal pockets than those without statin medication (P=0.00043). PIBI, which combines and unifies the data on PPD, was 40% smaller in statin using patients than in patients without statin (P=0.00069). PIBI of subjects on simvastatin and atorvastatin both differed significantly from patients without statin and were on the same level. The subjects' number of teeth had no effect on the results Conclusions Patients on statin medication exhibit fewer signs of periodontal inflammatory injury than subjects without the statin regimen. PIBI provides a tool for monitoring inflammatory load of chronic periodontitis. The apparent beneficial effects of statins may in part be mediated by their pleiotropic anti-inflammatory effect on periodontal tissue. (Source: BMC Oral Health - Latest articles)
