Information was derived from a 124-item questionnaire which included 14 socio-demographic items and 29 items asking about ICT use. ICT items were derived from a University of Birmingham, UK, battery. Data was collected in July and August 2004. A total of 162 of the 249 dental students participated in the study. The average age of students was 21.0 years (SD 2.4 years). The majority of participants (62.1%) were female. All participants had access to a computer, and 96.4% used the Internet. Most students had home Internet connections (73.4%). The most commonly used Internet sites on at least a weekly basis were: email (92.2%); and search engines (88.3%). However, a very few (21.1%) used the Internet to search for dental information for their studies on at least a weekly basis. Furthermore, although the majority (70.4%) found Internet use easy/very easy, 56.2% indicated that any search for information was easy/very easy. The majority (72.2%) indicated that the use of virtual education would not affect their class attendance. The final multivariate model explained 26% of the variance in ICT use, significant predictors for ICT use were gender, year of study, level of difficulty in using Internet, and place of Internet use. However, Internet use was mostly for non-dental purposes.

Partial caries removal in symptomless teeth reduces the risk of pulp exposure

Prolonged effect of a mother-child caries preventive program on dental caries in the permanent 1st molars in 9 to 10-year-old children

MATERIAL AND METHODS The permanent 1st molars of 37 children in the PDP group were evaluated for caries, both clinically and radiographically, and compared with those of a control group of 42 children who had not participated in the PDP. RESULTS Of children in the PDP group, 70\% were caries free compared to 33\% in the control group (p{\textless}0.001). Of permanent 1st molars in the PDP group, 87\% were caries-free compared to 61\% in the control group (p{\textless}0.001). The mean DFS of the PDP children 10 years of age was 0.519+/-0.93 versus 1.57+/-1.38 for the control children (p=0.002). CONCLUSIONS Examination of children 4 years after discontinuation of a caries preventive program reflected a long-term reduction in the DFS score of permanent 1st molars.

These facts create difficulties in transferring research results into practice, thereby delaying the benefits of medical advances to patients. The clinician can be kept up to date by learning how to practice Evidence-Based Orthodontics (EBO). Evidence-based Orthodontics combines clinical experience with the best available patient-centred medical knowledge. It involves finding the best studies (the best "external evidence") to answer the clinical questions we face in everyday clinical practice. This review introduces the concept of EBO, its principles, practice, and methodological steps: 1) formulation of a structured clinical question; 2) search of scientific evidence; 3) critical appraisal of this evidence using explicit methods; and 4) synthesis and practical application of this evidence. An example illustrate this process.

MATERIALS AND METHODS A total of 26 proximal noncavitated caries lesions were sealed in vivo, using a sealant in 13 premolars with orthodontic indication of extraction. Each tooth was randomly assigned to mesial or distal surface application of a sealant in the lesion area and in surrounding sound enamel, with or without a bonding system. Four groups were analyzed: a nonbonding group in the lesion area (NBL); a nonbonding group in sound enamel (NBS); a bonding group in the lesion area (BL) and a bonding group in sound enamel (BS). The premolars were extracted after two weeks. All sealed areas were cut and demineralized with 37\% hydrochloric acid for 24 h. For each group, the resin tags were observed and measured by scanning electron microscopy. RESULTS The lesion areas showed a very irregular resin network with twisted and curved tags in contrast to the sound enamel where a regular etching pattern was observed. The length of resin tags in microns for each group (mean +/-SD) was: NBG-L = 4.19 +/- 1.59; NBG-S = 5.49 +/- 2.49; BG-L = 4.57 +/- 1.99; and BG-S = 4.21 +/- 1.87. The differences between the groups were not statistically significant (p = 0.34). Conclusion: The use of a bonding system prior to the application of a pit and fissure sealant on both lesion and sound enamel areas does not increase the resin penetration length under non-contaminated conditions.

Potential of information technology in dental education

In order to produce a working document for the dental educator, this paper focuses on those methods where IT can assist in the education and competence development of dental students and dentists (e.g. e-learning, distance learning, simulations and computer-based assessment). Web pages and other information-gathering devices have become an essential part of our daily life, as they provide extensive information on all aspects of our society. This is mirrored in dental education where there are many different tools available, as listed in this report. IT offers added value to traditional teaching methods and examples are provided. In spite of the continuing debate on the learning effectiveness of e-learning applications, students request such approaches as an adjunct to the traditional delivery of learning materials. Faculty require support to enable them to effectively use the technology to the benefit of their students. This support should be provided by the institution and it is suggested that, where possible, institutions should appoint an e-learning champion with good interpersonal skills to support and encourage faculty change.From a global prospective, all students and faculty should have access to e-learning tools. This report encourages open access to e-learning material, platforms and programs. The quality of such learning materials must have well defined learning objectives and involve peer review to ensure content validity, accuracy, currency, the use of evidence-based data and the use of best practices. To ensure that the developers’ intellectual rights are protected, the original content needs to be secure from unauthorized changes. Strategies and recommendations on how to improve the quality of e-learning are outlined. In the area of assessment, traditional examination schemes can be enriched by IT, whilst the Internet can provide many innovative approaches. Future trends in IT will evolve around improved uptake and access facilitated by the technology (hardware and software). The use of Web 2.0 shows considerable promise and this may have implications on a global level. For example, the one-laptop-per-child project is the best example of what Web 2.0 can do: minimal use of hardware to maximize use of the Internet structure. In essence, simple technology can overcome many of the barriers to learning. IT will always remain exciting, as it is always changing and the users, whether dental students, educators or patients are like chameleons adapting to the ever-changing landscape.

DATA SOURCES The Cochrane Oral Health Group's specialised trial register (Cochrane Central Regist... more DATA SOURCES The Cochrane Oral Health Group's specialised trial register (Cochrane Central Register of Controlled Trials) was searched along with Medline, Embase and the System for Information on Grey Literature in Europe, along with proceedings from conferences on early childhood caries, restorative materials for paediatric dentistry, and material sciences conferences for dental materials used for children's dentistry. There were no language restrictions. Additionally, the reference lists from articles of eligible papers were searched, and handsearches made of the journals Operative Dentistry, Journal of Restorative Dentistry, Pediatric Dentistry, Journal of Clinical Pediatric Dentistry, and the International Journal of Paediatric Dentistry. Authors and manufacturers of dental materials were individually contacted. STUDY SELECTION Randomised controlled trials (RCT) or quasi-RCT with a minimum period of 6 months' followup were included. Both parallel group and split-mouth study designs were considered. The unit of randomisation could be the individual, group (school, school class, etc), tooth or tooth pair. Included studies had a dropout rate of less than 30\%. The eligible trials consisted of young children (children aged less than 12 years) with tooth decay involving at least one tooth in the primary dentition which was symptomatic or symptom-free at the start of the study. DATA EXTRACTION AND SYNTHESIS Data were independently extracted, in duplicate, by two review authors. Disagreements were resolved by consultation with a third review author. Authors were contacted for missing or unclear information regarding randomisation, allocation sequence, presentation of data, etc. A quality assessment of included trials was undertaken. The Cochrane Collaboration statistical guidelines were followed for data analysis. RESULTS Only three studies were included in this review. One study assessed the clinical performance of aesthetic crowns versus conventional stainless steel crowns in 11 children who had at least two mandibular primary molars that required a crown restoration. The outcomes assessed at 6 months included gingival health restoration failure occlusion, proximal contact and marginal integrity. The second (split-mouth) study compared a resin-modified glass ionomer with amalgam over a 36-month period. Forty pairs of Class II restorations were placed in 40 patients (21 males and 19 females; mean age 8 years +/-1.17 years). Although the study period was 36 months, only the 6- and 12-month results are reported because of the loss to followup of patients being greater than 30\% for the 24- and 36-month data. The third study recruited 30 patients (age range, 4-9 years) with one pair of primary molars that required a Class II restoration. The materials tested were a compomer and amalgam. Loss to followup at 24 and 36 months was 20\% and 43\% respectively. This meant that only the 24-month data were usable. For all of the outcomes compared in all three studies, there were no significant differences in clinical performance between the materials tested. No studies were found that compared restorations with extractions or with no treatment as an intervention in children with childhood caries. CONCLUSIONS It was disappointing that only three trials that compared three different types of materials were suitable for inclusion into this review. There were no significant differences found in all three trials for all of the outcomes assessed. Well-designed RCT comparing the different types of filling materials for similar outcomes are urgently needed in dentistry. There was insufficient evidence from the three included trials to make any recommendations about which filling material to use.

Method: We performed a database search of PubMed, Scielo and Google Scholar, using: cervical vertebrae, hand-wrist and maturation key terms and selected all those articles published between the years 1990 and 2011 that fulfilled the following criteria: a) they were correlational studies of transversal or diagnostic cut; b) radiographs of hand and wrist, as well as lateral teleradiography were used to determine skeletal maturation, and c) they correlated both methods via Spearman’s rho. We compare analysis with the same method (e.g. Bacetti vs Bacetti). Method quality was determined using the QUADAS tool. Result: We found 174 articles, of which 35 were filtered by title and summary, to find that a final 11 fulfilled the inclusion criteria. Most used analysis methods were Lamparski, Bacetti, ...

Methods: In this equivalence clinical trial, 82 patients underwent removal maxillary teeth were randomly assigned to receive low (1.2ml) or traditional (1.8ml) dose of 2% lidocaine-hydrochloride with 1:50,000 epinephrine for troncular maxillary nerve block anesthesia via the greater palatine canal. Visual Analogue Scale (VAS), patient declared pain, additional anesthesia required and any adverse effects were evaluated and significant differences with chi-square test were calculated (p&lt;0.05). Results: The low-dose group (LDG) exhibited 2,9 mean VAS and 2.8 for traditional-group (TDG) (p=.15). Fifty-six percent of patients in LDG perceived no pain meanwhile 59.1% of TDG (p=.21). Five patients in LDG shows collateral effects andone in TDG (p=0.56). The most common collateral effect was transient diplopia. Conclusion: There was no significant differences in anesthesic efficacy and percentage of collateral effects for for troncular maxillary nerve block anesthesia via the greater palatine canal with the use of low or traditional dose of 2% lidocaine withepinephrine. therefore, low dose of troncular anesthesia can be considered as effective as traditional dose for maxillary tooth extractions.

Study selection Articles were selected for inclusion in the review if they were randomised or quasi-randomised controlled trials of at least 12 months in duration and if sealants were used for preventing caries in children and adolescents of under 20 years of age. Both parallel group and split-mouth study designs were included. The primary outcome was the increment in the numbers of carious occlusal surfaces of premolars and molars. Data extraction and synthesis In the first phase, two reviewers independently examined whether a given study was likely to be relevant on the basis of the title, keywords and abstract. In the second phase, four of the reviewers independently classified whether studies would be included in final analyses. Study authors were contacted for additional information. In the split-mouth studies, relative risk (RR) ratios were calculated for the paired differences of tooth surfaces being carious or not. In studies that compared resin-based sealant with no treatment, fixed-effect meta-analyses were used to combine the estimates of RR ratios. In one parallel-group study, the effect-estimate was calculated from data of occlusal surfaces of teeth included in the test and control groups. Results Eight trials were included in this review, of which seven were split-mouth studies and one a parallel-group study. Six studies provided data for comparing sealant with no treatment and three studies compared glass ionomers (GI) with resin-based sealants. The overall effectiveness of resin-based sealants in preventing dental decay on first molars was high. Based on five split-mouth studies with 5-10-year-old children there were significant differences in favour of the secondgeneration resin sealant compared with no treatment. Pooled RR values were 0.14, 0.24, 0.30 and 0.43 at 12, 24, 36 and 48-54 months, respectively. The reductions in caries therefore ranged from 86% at 12 months to 57% at 48-54 months. The 24-month parallel group study that compared second-generation resin sealant with control in 12-13year old children also found significantly more caries in the control group children with a DFS of 0.65 (95% confidence interval, 0.47-0.83). Allocation concealment was classified as adequate in three of these six studies. The information on background levels of caries in the
