Resin infiltration: An effective adjunct strategy for managing high caries risk-A within-person randomized controlled clinical trial.

OBJECTIVES: Micro-invasive resin-infiltration has shown to inhibit lesion progression of proximal non-cavitated carious lesions, suggesting an alternative to early operative treatment. This split-mouth, randomized placebo-controlled clinical trial evaluated the effects of proximal lesion infiltration supplementary to standard-of-care management in high caries risk (HCR)-patients. METHODS: Forty-two HCR-subjects with two similar interproximal posterior lesions received professional HCR-regimen including repeated F-varnish applications. Two affected E2/D1-surfaces were randomized and concurrently treated by resin-infiltration or mock-infiltration (control). Individually standardized digital radiographs provided visual determination of lesion-size distribution at baseline and 2-year follow-up. Data were analyzed by logistic regression and McNemar's test. RESULTS: Thirty-two lesion pairs (76%) were evaluated after 2 years. Categorical lesion depths were not different between groups (P > .5). Comparative pairwise assessment (image sets BL-2 yr) showed significantly more progression in control (7) versus infiltration (1) lesions (P = .035). Cumulative prevented fraction after two years was 97% for infiltrated lesions versus 74% for control lesions. CONCLUSIONS: Two-year follow-up showed resin infiltration to be a highly efficacious (RRR: 86-89%) therapy. Long-term follow-up is needed to strengthen the evidence for efficacy of resin-infiltration as an adjunct to standard-of-care HCR-regimen including F-varnish. CLINICAL SIGNIFICANCE: Showing 24% more stabilized lesions, the resin-infiltrated group performed significantly better than their controls, confirming successful early lesion management. Adjunct resin-infiltration provided an effective micro-invasive approach to inhibit short-term lesion progression.

Efficacy of Articaine versus Lidocaine in Supplemental Infiltration for Mandibular First versus Second Molars with Irreversible Pulpitis: A Prospective, Randomized, Double-blind Clinical Trial.

INTRODUCTION: Profound pulpal anesthesia is difficult to achieve in mandibular molars with irreversible pulpitis (IP). However, there are no published randomized controlled clinical trials comparing the success of supplemental buccal infiltration (BI) in mandibular first versus second molars with IP. The purpose of this prospective, randomized, double-blind study was to compare the efficacy of 4% articaine with 2% lidocaine for supplemental BIs in mandibular first versus second molars with IP after a failed inferior alveolar nerve block (IANB). This study's sample was combined with data from a previous trial. METHODS: One hundred ninety-nine emergency subjects diagnosed with IP of a mandibular molar were selected and received an IANB with 4% articaine. Subjects who failed to achieve profound pulpal anesthesia, determined by a positive response to cold or pain upon access, randomly received 4% articaine or 2% lidocaine as a supplemental BI. Endodontic access was begun 5 minutes after infiltration. Success was defined as less than mild pain during endodontic access and instrumentation on the Heft-Parker visual analog scale. RESULTS: There was a 25% IANB success rate with 4% articaine. The success rate for articaine supplemental BI in first molars was 61% versus 63% for second molars (P > .05). The success of lidocaine in first molars was 66%, but for second molars it was 32% (P = .004). CONCLUSIONS: The success rate for IANB with 4% articaine was 25%. Articaine and lidocaine had similar success rates for supplemental infiltration in first molars, whereas articaine was significantly more successful for second molars. However, because BI often did not provide profound pulpal anesthesia, additional techniques including intraosseous anesthesia may still be required.

Interventions for prevention of herpes simplex labialis (cold sores on the lips).

BACKGROUND: Herpes simplex labialis (HSL), also known as cold sores, is a common disease of the lips caused by the herpes simplex virus, which is found throughout the world. It presents as a painful vesicular eruption, forming unsightly crusts, which cause cosmetic disfigurement and psychosocial distress. There is no cure available, and it recurs periodically. OBJECTIVES: To assess the effects of interventions for the prevention of HSL in people of all ages. SEARCH METHODS: We searched the following databases up to 19 May 2015: the Cochrane Skin Group Specialised Register, the Oral Health Group Specialised Register, CENTRAL in the Cochrane Library (Issue 4, 2015), MEDLINE (from 1946), EMBASE (from 1974), LILACS (from 1982), the China National Knowledge Infrastructure (CNKI) database, Airiti Library, and 5 trial registers. To identify further references to relevant randomised controlled trials, we scanned the bibliographies of included studies and published reviews, and we also contacted the original researchers of our included studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) of interventions for preventing HSL in immunocompetent people. DATA COLLECTION AND ANALYSIS: Two authors independently selected trials, extracted data, and assessed the risk of bias. A third author was available for resolving differences of opinion. MAIN RESULTS: This review included 32 RCTs, with a total of 2640 immunocompetent participants, covering 19 treatments. The quality of the body of evidence was low to moderate for most outcomes, but was very low for a few outcomes. Our primary outcomes were 'Incidence of HSL' and 'Adverse effects during use of the preventative intervention'.The evidence for short-term (≤ 1 month) use of oral aciclovir in preventing recurrent HSL was inconsistent across the doses used in the studies: 2 RCTs showed low quality evidence for a reduced recurrence of HSL with aciclovir 400 mg twice daily (risk ratio (RR) 0.26, 95% confidence interval (CI) 0.13 to 0.51; n = 177), while 1 RCT testing aciclovir 800 mg twice daily and 2 RCTs testing 200 mg 5 times daily found no similar preventive effects (RR 1.08, 95% CI 0.62 to 1.87; n = 237; moderate quality evidence and RR 0.46, 95% CI 0.20 to 1.07; n = 66; low quality evidence, respectively). The direction of intervention effect was unrelated to the risk of bias. The evidence from 1 RCT for the effect of short-term use of valaciclovir in reducing recurrence of HSL by clinical evaluation was uncertain (RR 0.55, 95% CI 0.23 to 1.28; n = 125; moderate quality evidence), as was the evidence from 1 RCT testing short-term use of famciclovir.Long-term (> 1 month) use of oral antiviral agents reduced the recurrence of HSL. There was low quality evidence from 1 RCT that long-term use of oral aciclovir reduced clinical recurrences (1.80 versus 0.85 episodes per participant per a 4-month period, P = 0.009) and virological recurrence (1.40 versus 0.40 episodes per participant per a 4-month period, P = 0.003). One RCT found long-term use of valaciclovir effective in reducing the incidence of HSL (with a decrease of 0.09 episodes per participant per month; n = 95). One RCT found that a long-term suppressive regimen of valaciclovir had a lower incidence of HSL than an episodic regimen of valciclovir (difference in means (MD) -0.10 episodes per participant per month, 95% CI -0.16 to -0.05; n = 120).These trials found no increase in adverse events associated with the use of oral antiviral agents (moderate quality evidence).There was no evidence to show that short-term use of topical antiviral agents prevented recurrent HSL. There was moderate quality evidence from 2 RCTs that topical aciclovir 5% cream probably has little effect on preventing recurrence of HSL (pooled RR 0.91, 95% CI 0.48 to 1.72; n = 271). There was moderate quality evidence from a single RCT that topical foscarnet 3% cream has little effect in preventing HSL (RR 1.08, 95% CI 0.82 to 1.40; n = 295).The efficacy of long-term use of topical aciclovir cream was uncertain. One RCT found significantly fewer research-diagnosed recurrences of HSL when on aciclovir cream treatment than on placebo (P < 0.05), but found no significant differences in the mean number of participant-reported recurrences between the 2 groups (P ≥ 0.05). One RCT found no preventive effect of topical application of 1,5-pentanediol gel for 26 weeks (P > 0.05). Another RCT found that the group who used 2-hydroxypropyl-ß-cyclo dextrin 20% gel for 6 months had significantly more recurrences than the placebo group (P = 0.003).These studies found no increase in adverse events related to the use of topical antiviral agents.Two RCTs found that the application of sunscreen significantly prevented recurrent HSL induced by experimental ultraviolet light (pooled RR 0.07, 95% CI 0.01 to 0.33; n = 111), but another RCT found that sunscreen did not prevent HSL induced by sunlight (RR 1.13, 95% CI 0.25 to 5.06; n = 51). These RCTs did not report adverse events.There were very few data suggesting that thymopentin, low-level laser therapy, and hypnotherapy are effective in preventing recurrent HSL, with one to two RCTs for each intervention. We failed to find any evidence of efficacy for lysine, LongoVital® supplementation, gamma globulin, herpes simplex virus (HSV) type I subunit vaccine, and yellow fever vaccine in preventing HSL. There were no consistent data supporting the efficacy of levamisole and interferon, which were also associated with an increased risk of adverse effects such as fever. AUTHORS' CONCLUSIONS: The current evidence demonstrates that long-term use of oral antiviral agents can prevent HSL, but the clinical benefit is small. We did not find evidence of an increased risk of adverse events. On the other hand, the evidence on topical antiviral agents and other interventions either showed no efficacy or could not confirm their efficacy in preventing HSL.

Efficacy of articaine versus lidocaine as a supplemental buccal infiltration in mandibular molars with irreversible pulpitis: a prospective, randomized, double-blind study.

INTRODUCTION: Profound pulpal anesthesia in mandibular molars with irreversible pulpitis (IP) is often difficult to obtain and often requires supplemental injections after an ineffective inferior alveolar nerve block (IANB). The purpose of this prospective, randomized, double-blind study was to compare the efficacy of 4% articaine with 2% lidocaine for supplemental buccal infiltrations (BIs) after an ineffective IANB in mandibular molars with IP. In addition, the use of articaine for IANB and intraosseous injections was investigated. METHODS: One hundred emergency patients diagnosed with IP of a mandibular molar were selected and received an IANB with 4% articaine. All injections were 1.7 mL with 1:100,000 epinephrine. All patients reported profound lip numbness after IANB. Patients with ineffective IANB (positive pulpal response to cold or pain on access) randomly received 4% articaine or 2% lidocaine as a supplemental BI. Endodontic access was initiated 5 minutes after deposition of the infiltration solution. Success was defined as no pain or no more than mild pain during endodontic access and instrumentation as measured on a visual analogue scale. RESULTS: Seventy-four patients failed to achieve pulpal anesthesia after IANB with 4% articaine, resulting in IANB success rate of 26%. Success rates for supplemental BIs were 62% for articaine and 37% for lidocaine (P < .05). This effect was most pronounced in second molars (P < .05). CONCLUSIONS: Supplemental BI with articaine was significantly more effective than lidocaine. The IANB success rate of 4% articaine confirmed published data.

Students' clinical learning in an emerging dental school: an investigation in international collaboration between Michigan and Ghana.

The dearth of dental faculty members is a widely known problem that is exacerbated in countries that are attempting to begin dental education programs. This collaboration between Kwame Nkrumah University of Science and Technology and the University of Michigan investigated if dental students who have just started their clinical dental education can learn the knowledge and skills required for identifying and restoring cavitated caries lesions through compact course delivery. There were three instructional blocks: 1) didactic seminar; 2) seminar, simulated hands-on skills instruction, and clinical observation/assisting with treatment of schoolchildren; and 3) seminar, simulated skills training, and application to schoolchildren. Each dental student completed a questionnaire measuring knowledge and perceptions of knowledge, experience, and confidence at five points in time. The dental students' knowledge increased significantly as well as their perceived knowledge, experience, and confidence (p<0.0001). In general, the students showed proficiency in delivering simple treatments. The project showed that an integrated compact course delivery model may assist emerging dental schools to cope with the challenging shortage of resident faculty members.

Assessment of restorative treatment of patients with amelogenesis imperfecta.

PURPOSE: The purpose of this study was to assess restorative treatment outcomes in the mixed dentition of amelogenesis imperfecta (AI) patients and determine the postrehabilitation oral health status and satisfaction of the patients. METHODS: Clinical and radiographic examinations were performed on eight AI patients, who had 74 restorations placed in permanent incisors and molars, to allow evaluation of the integrity of the restorations and periodontal status post-treatment. Subjects completed a survey regarding esthetics, function, and sensitivity. RESULTS: Among the 74 restorations evaluated, seven were lost; of the remaining restorations, 31 were posterior, and 36 were anterior. Ten were rated clinically unacceptable. Teeth with stainless steel crowns had a moderate gingival index (mean=2.3) and plaque index (mean=2.0) scores. Widening of the periodontal ligament and pulp canal obliteration were common radiographic findings. Subject's recall of satisfaction regarding esthetics (P=.002) and sensitivity (brushing-P=.03; eating-P=.01) showed a statically significant difference before and after treatment. CONCLUSIONS: During mixed dentition, teeth with amelogenesis imperfecta may be restored with conventional treatment modalities. Direct restorations should be considered "interim" with multiple repairs anticipated. Post-treatment, gingival inflammation and plaque accumulation were observed. Subjects were satisfied with their appearance and reported a decrease of hypersensitivity.

Minimal intervention dentistry for managing dental caries - a review: report of a FDI task group.

This publication describes the history of minimal intervention dentistry (MID) for managing dental caries and presents evidence for various carious lesion detection devices, for preventive measures, for restorative and non-restorative therapies as well as for repairing rather than replacing defective restorations. It is a follow-up to the FDI World Dental Federation publication on MID, of 2000. The dental profession currently is faced with an enormous task of how to manage the high burden of consequences of the caries process amongst the world population. If it is to manage carious lesion development and its progression, it should move away from the 'surgical' care approach and fully embrace the MID approach. The chance for MID to be successful is thought to be increased tremendously if dental caries is not considered an infectious but instead a behavioural disease with a bacterial component. Controlling the two main carious lesion development related behaviours, i.e. intake and frequency of fermentable sugars, to not more than five times daily and removing/disturbing dental plaque from all tooth surfaces using an effective fluoridated toothpaste twice daily, are the ingredients for reducing the burden of dental caries in many communities in the world. FDI's policy of reducing the need for restorative therapy by placing an even greater emphasis on caries prevention than is currently done, is therefore, worth pursuing.

The pulpal anesthetic efficacy of articaine versus lidocaine in dentistry: a meta-analysis.

BACKGROUND: The authors evaluated published evidence from controlled clinical trials regarding the efficacy of two local anesthetic solutions in providing successful pulpal anesthesia. METHODS: The authors searched MEDLINE and Embase databases to identify peer-reviewed randomized controlled trials in which researchers directly compared articaine and lidocaine local anesthetic solutions in adult participants. They extracted study characteristics and outcomes data as a basis for meta-analysis. They completed subgroup analyses for both infiltration and mandibular inferior alveolar block anesthetic techniques. RESULTS: Articaine solutions had a probability of achieving anesthetic success superior to that of lidocaine, with an odds ratio of 2.44 (95 percent confidence interval [CI], 1.59-3.76; P < .0001). The greater odds ratio for articaine increased to 3.81 (95 percent CI, 2.71-5.36; P < .00001) when the authors analyzed only infiltration data. There was weaker, but still significant, evidence of articaine's being superior to lidocaine for mandibular block anesthesia, with an odds ratio of 1.57 (95 percent CI, 1.12-2.21; P = .009), and no difference when the authors considered only symptomatic teeth. CLINICAL IMPLICATIONS: Research evidence supports using articaine versus lidocaine for achieving pulpal anesthesia when the infiltration mode of administration is used. It is premature to recommend articaine for mandibular block anesthesia in cases involving irreversible pulpitis.

Incidence of caries lesions among patients treated with comprehensive orthodontics.

INTRODUCTION: Dental caries, specifically decalcified white-spot lesions (WSL), is a well-known side-effect of orthodontic treatment. The incidence of labial incipient caries lesions and its relationship with various patient and treatment variables was investigated in patients treated with comprehensive orthodontics. METHODS: Randomly selected orthodontic patient records (n = 350) were examined to determine incipient caries lesion development. Labial surfaces on pretreatment and posttreatment photographs were scored with a standardized scoring system. Independent variables were collected by chart abstraction. RESULTS: The incidence of patients who developed at least 1 new WSL during treatment was 72.9%, and this incidence was 2.3% for cavitated lesions. Treatment duration was significantly associated with new WSL development (P = 0.03). Development of WSL and cavitated lesions increased (both, P <0.00) despite increased attention to oral hygiene during treatment. Sex, age, extraction therapy, and various fluoridation sources were not associated with WSL development, but initial oral-hygiene score was moderately associated (P <0.06). CONCLUSIONS: The incidence of WSL in patients treated with comprehensive orthodontics was significantly high, and the preventive therapy provided appeared to be ineffective. This widespread problem is alarming and warrants significant attention from both patients and providers that should result in greatly increased emphasis on effective caries prevention.

A qualitative examination of patient awareness and understanding of type 2 diabetes and oral health care needs.

AIMS: The study examined awareness and understanding of the bidirectional relationship between type 2 diabetes and oral health care in adult patients with type 2 diabetes. METHODS: Focus groups were held with 30 participants with type 2 diabetes. Groups were comprised of African Americans (n=16), Hispanics (n=6), and Caucasians (n=8). A grounded theory approach was used to analyse and interpret findings. RESULTS: Participants were unaware of the relationship between type 2 diabetes and oral health but were concerned about the influence of poor oral health on quality of life. Having diabetes was reported as a potential challenge for the coordination and receipt of dental care. Patient-provider communication of diabetes and oral health needs were perceived to be inadequate. CONCLUSIONS: Patients with type 2 diabetes are at-risk for poor oral health, yet have limited awareness and understanding of the specific oral health care needs and risks associated with type 2 diabetes. This lack of awareness and understanding of the relationship between diabetes and oral health may be an indicator of inadequate oral health literacy. Addressing the relationship between diabetes and oral health with patients may improve dental outcomes, increase quality of life, and promote oral health literacy in at-risk populations.

In-vitro evaluation of various treatments to prevent demineralization next to orthodontic brackets.

INTRODUCTION: One common negative side effect of orthodontic treatment with fixed appliances is the development of incipient caries lesions around brackets, particularly in patients with poor oral hygiene. Bio-available minerals from cement containing amorphous calcium phosphate (ACP) might facilitate remineralization and inhibit lesion development. Our objective was to compare the potential of ACP-containing resin cement, fluoride varnish, resin sealer, and MI Paste (GC America, Alsip, Ill) under similar in-vitro conditions to prevent incipient caries lesions next to brackets on teeth. METHODS: One hundred extracted premolars were randomly allocated to 5 groups (n = 20). Brackets were bonded with ACP cement (Aegis-Ortho, Bosworth, Skokie, Ill), resin (Transbond XT [3M Unitek, Monrovia, Calif], control), or resin followed by application of fluoride varnish (Vanish, 3M, St Paul, Minn), resin sealer (Pro-seal, Reliance Orthodontic Products, Itasca, Ill), or casein phosphopeptide-ACP paste (MI Paste). All groups were cycled for 15 days in demineralization solution for 8 hours a day, rinsed, placed in artificial saliva (30 minutes), brushed, and stored overnight in artificial saliva. The extent of demineralization in each group was assessed by using quantitative light-induced fluorescence and confocal laser scanning microscopy. RESULTS: Only the Pro-seal and Vanish groups showed significantly smaller lesions than the controls (Kruskal-Wallis test, P <0.05) for both quantitative light-induced fluorescence and confocal laser scanning microscopy measurements. Fluorescence loss of Aegis-Ortho was similar to Vanish; Aegis-Ortho, MI Paste, and the controls were not different from each other. CONCLUSIONS: Both light-cured filled resin (Pro-seal) and fluoride varnish (Vanish) might prevent enamel demineralization next to orthodontic brackets exposed to cariogenic conditions, but the observed positive effects of Aegis-Ortho and MI Paste were not significant.

Strategies for noninvasive demineralized tissue repair.

This article provides a state-of-the-art overview of clinically relevant evidence regarding effective, noninvasive management strategies to prevent, arrest, and remineralize caries lesions. With the rapidly increasing knowledge about oral biofilms and the process of caries in itself, the profession is embarking on new strategies. This is an exciting time, with several promising new agents and novel treatment modalities at the horizon to prevent and manage caries lesions. Some are already available in clinical practice. Studies, however, have yet to show conclusive evidence of clinical efficacy. None have shown to be more effective than fluoride and protection by sealant.

Effectiveness of gloves and infection control in dentistry: student and provider perspectives.

The objectives of this study were to explore dental and dental hygiene students', graduate students', and dental professionals' preferences for certain types of gloves and the reasons for these preferences (Aim 1), as well as determining their knowledge, attitudes, and behavior concerning the use of dental gloves as a means of barrier protection (Aim 2). Data were collected from 198 dental and forty-six dental hygiene students, thirty-five graduate students, and seventy-nine dental professionals (twenty-eight dentists and fifty-one dental hygienists in private practice). The subjects responded to a self-administered anonymous survey. Professionals (dentists: 96.4 percent and dental hygienists: 92.2 percent) were found to be more likely to have a preference for certain types of gloves than students (dental students: 79.2 percent and dental hygiene students: 76 percent) and graduate students (77.1 percent; p=.033). "Comfort" was most frequently reported as a reason for glove preference. Large percentages of respondents wrongly believed that gloves provide full protection (students: 50.8 percent; graduate students: 25.7 percent; professionals: 30.4 percent), thought that gloves provide protection as long as there is no visible tear (students: 39.7 percent; graduate students: 28.6 percent; professionals: 18.2 percent), and reported that they would not change gloves during an uninterrupted three-hour long procedure (students: 32.2 percent; graduate students: 23.5 percent; professionals: 22.7 percent). These findings should alert dental educators about the importance of educating their students as well as practicing professionals clearly and comprehensively about infection control and the science and rationale supporting recommended guidelines.

Influence of occlusal access on demineralized dentin removal in the atraumatic restorative treatment (ART) approach.

PURPOSE: To verify the influence of cavity access diameter on demineralized dentin removal in the ART approach. METHODS: 40 non-carious human premolars were randomly divided into four groups. The occlusal surface was ground flat and the teeth were sectioned mesio-distally. The hemi-sections were reassembled and occlusal access preparations were carried out using ball-shaped diamonds. The resulting size of the occlusal opening was 1.0 mm, 1.4 mm, 1.6 mm and 1.8 mm for Groups A, B, C, and D, respectively. Standardized artificial carious lesions were created and demineralized dentin was excavated. After excavation, the cavities were analyzed using: (a) the tactile method, (b) caries-detection dye to stain demineralized dentin, as proposed by Smales & Fang, and (c) Demineralized Tissue Removal index, as proposed in this study. Statistical analysis was performed using Fisher, Spearman correlation coefficient, kappa, Kruskal-Wallis and Miller tests (P < 0.05). RESULTS: The three methods of evaluation showed no significant difference between Groups A vs. B, and C vs. D, while statistically significant differences were observed between Groups A vs. C, A vs. D, B vs. C and B vs. D. Based on the results of this study, the size of occlusal access significantly affected the efficacy of demineralized tissue removal.
