an assessment of direct restorative material use in Posterior Teeth by american and canadian pediatric dentists ii rubber dam isolation
Pediatric Dentistry, 2016Co-Authors: Rae E Varughese, Paul Andrews, Michael J Sigal, Amir AzarpazhoohAbstract:PURPOSE The purpose of this study was to assess usage, indications, and contraindications for rubber dam isolation (RDI) by pediatric dentists in Canada and the United States. METHODS A cross-sectional, web-based, self-administered survey was utilized to collect the opinions of all active pediatric dentist members of the Royal College of Dentists of Canada and the American Academy of Pediatric Dentistry on the use of direct restorative materials in Posterior Teeth (n equals 4,648; 19.3 percent response rate). The main survey also included a domain on the RDI utilization and its perceived indications and contraindications. Bivariate and multivariate analyses for RDI usage and its predictor were performed at two-tailed P<0.05. RESULTS A response rate of 19.3 percent was obtained. Most participants (72.5 percent) reported using RDI "all the time." The material with the lowest usage of RDI was composite (82 percent) in the primary dentition and stainless steel crown (80.7 percent) in the permanent dentition. The three top-noted reasons for not using RDI included decreased trauma to the patient (66.2 percent), being able to prevent soft tissue from interfering without using RDI (55.9 percent), and decreased time for appointments (45.6 percent). CONCLUSION Rubber dam isolation was valued by the majority of pediatric dentists when restoring primary and permanent dentition for all materials.

an assessment of direct restorative material use in Posterior Teeth by american and canadian pediatric dentists i material choice
Pediatric Dentistry, 2016Co-Authors: Rae E Varughese, Paul Andrews, Michael J Sigal, Amir AzarpazhoohAbstract:PURPOSE The purpose of this study was to assess the preferences of pediatric dentists in Canada and the United States about clinical decision-making related to the placement of direct restorative materials. METHODS A cross-sectional web-based survey was used to collect the preference of all active pediatric members of the Royal College of Dentists of Canada and the American Academy of Pediatric Dentistry on the use of direct restorative materials in Posterior Teeth in healthy, developmentally delayed (DD), and medically compromised (MC) children. Bivariate and multivariate analyses were performed to determine the association between the predictor variables and all materials at two-tailed P<0.05. RESULTS A response rate of 19.3 percent (n equals 762) was achieved. For DD patients, stainless steel crowns were the most preferred material for primary Teeth, and a similar frequency of amalgam and composite were preferred for permanent Teeth. Amalgam usage was increasingly preferred in the DD population versus healthy and MC patients. CONCLUSIONS Composite resin was the most preferred restoration for Class I, II, and V restorations in primary and permanent Teeth in healthy and medically compromised individuals. In DD individuals, stainless steel crowns and amalgam were preferred more frequently.

an assessment of direct restorative material use in Posterior Teeth by american and canadian pediatric dentists iii preferred level of participation in decision making
Pediatric Dentistry, 2016Co-Authors: Rae E Varughese, Paul Andrews, Michael J Sigal, Amir AzarpazhoohAbstract:PURPOSE The purpose of this study was to assess Canadian and American pediatric dentists' preferred level of participation in clinical decision-making. METHODS A web-based survey was used to collect the opinions of all active Royal College of Dentists of Canada members and American Academy of Pediatric Dentistry members on the use of direct restorative materials in Posterior Teeth (n equals 4,648; 19.3 percent response rate). The main survey also included a domain to elicit participants' preferred role in clinical decision-making, ranging from an active role (the dentist takes the primary role in decision-making while considering patients/caregivers opinions) to a passive role (the dentist prefers to have the patient guide the decision-making). Bivariate and multivariate analyses for the preferred role and its predictor were performed (two-tailed P<0.05). RESULTS Fifty-eight percent of participants preferred an active role. The passive role was chosen three times more by those who worked in a hospital-based setting (odds ratio [OR] equals 3.15, 95 percent confidence interval [CI] equals 1.13 to 8.79) or a university-based setting versus a combined setting (OR equals 3.61, 95 percent CI equals 1.11 to 11.77). CONCLUSION The majority of participants preferred an active role in decision-making, a role that may not be consistent with a patient-centered practice that emphasizes patient autonomy in decision-making.

maxillary sinus and Posterior Teeth accessing close relationship by cone beam computed tomographic scanning in a brazilian population
Journal of Endodontics, 2013Co-Authors: Otavio Pagi, Una Stuchi Centurio, Izabel Regina Fische Rubirabulle, Ana Lucia Alvares CapelozzaAbstract:Abstract Introduction This study aimed to evaluate the close proximity established between the maxillary sinus floor and Posterior Teeth roots apices by using cone-beam computed tomographic scanning. Methods The relationship of maxillary sinuses and Posterior Teeth roots, which were divided into 2 groups, was analyzed using i-CAT Vision software (Imaging Sciences, Hatfield, PA). Group 1 included all root apices found in close contact with the maxillary sinus floor without sinus floor elevation, whereas group 2 included all root apices that were protruded within the sinus producing an elevation of the bony cortical. Results A total of 100 maxillary sinuses and 601 roots apices were evaluated. Group 1 presented 130 of 601 (21.6%) roots and group 2 presented 86 of 601 (14.3%) roots. Conclusions The second molar mesiobuccal root apex is frequently found in close proximity with the sinus floor, and the relation between these anatomic structures should be considered in order to prevent an iatrogenic procedure and minimize the risks from an infectious disease within the sinus.

articaine for supplemental buccal mandibular infiltration anesthesia in patients with irreversible pulpitis when the inferior alveolar nerve block fails
Journal of Endodontics, 2009Co-Authors: Rachel Matthews, Melissa Drum, Al Reader, John Nusstein, Mike BeckAbstract:The purpose of this prospective study was to determine the anesthetic efficacy of the supplemental buccal infiltration injection of a cartridge of 4% articaine with 1:100,000 epinephrine in mandibular Posterior Teeth diagnosed with irreversible pulpitis when the conventional inferior alveolar nerve (IAN) block failed. Fifty-five emergency patients, diagnosed with irreversible pulpitis of a mandibular Posterior tooth, received an IAN block and had moderate to severe pain on endodontic access. An infiltration of a cartridge of 4% articaine with 1:100,000 epinephrine was administered buccal to the tooth requiring endodontic treatment. Success of the infiltration injection was defined as no pain or mild pain on endodontic access or instrumentation. The results showed that anesthetic success was obtained in 58% of the mandibular Posterior Teeth. We can conclude that when the IAN block fails to provide profound pulpal anesthesia, the supplemental buccal infiltration injection of a cartridge of 4% articaine with 1:100,000 epinephrine would be successful 58% of the time for mandibular Posterior Teeth in patients presenting with irreversible pulpitis. Unfortunately, the modest success rate would not provide predictable pulpal anesthesia for all patients requiring profound anesthesia.

anesthetic efficacy of buccal and lingual infiltrations of lidocaine following an inferior alveolar nerve block in mandibular Posterior Teeth
Anesthesia Progress, 2007Co-Authors: William Foster, Melissa Drum, Mike BeckAbstract:The authors, using a crossover design, randomly administered, in a single-blind manner, 3 sets of injections: an inferior alveolar nerve block (IANB) plus a mock buccal and a mock lingual infiltration of the mandibular first molar, an IANB plus a buccal infiltration and a mock lingual infiltration of the mandibular first molar, and an IANB plus a mock buccal infiltration and a lingual infiltration of the mandibular first molar in 3 separate appointments spaced at least 1 week apart. An electric pulp tester was used to test for anesthesia of the premolars and molars in 3-minute cycles for 60 minutes. Anesthesia was considered successful when 2 consecutive 80 readings were obtained within 15 minutes following completion of the injection sets, and the 80 reading was continuously sustained for 60 minutes. For the IANB plus mock buccal infiltration and mock lingual infiltration, successful pulpal anesthesia ranged from 53 to 74% from the second molar to second premolar. For the IANB plus buccal infiltration and mock lingual infiltration, successful pulpal anesthesia ranged from 57 to 69% from the second molar to second premolar. For the IANB plus mock buccal infiltration and lingual infiltration, successful pulpal anesthesia ranged from 54 to 76% from the second molar to second premolar. There was no significant difference (P > .05) in anesthetic success between the IANB plus buccal or lingual infiltrations and the IANB plus mock buccal infiltration and mock lingual infiltration. We conclude that adding a buccal or lingual infiltration of 1.8 mL of 2% lidocaine with 1:100,000 epinephrine to an IANB did not significantly increase anesthetic success in mandibular Posterior Teeth.
