Accuracy of full-arch scans using intraoral scanners

, Volume 18, Issue 6, pp 1687-1694

Abstract

Objectives

This study aimed to evaluate the accuracy of intraoral scanners in full-arch scans.

Materials and methods

A representative model with 14 prepared abutments was digitized using an industrial scanner (reference scanner) as well as four intraoral scanners (iTero, CEREC AC Bluecam, Lava C.O.S., and Zfx IntraScan). Datasets obtained from different scans were loaded into 3D evaluation software, superimposed, and compared for accuracy. One-way analysis of variance (ANOVA) was implemented to compute differences within groups (precision) as well as comparisons with the reference scan (trueness). A level of statistical significance of p < 0.05 was set.

Results

Clinical Oral InvestigationsMean trueness values ranged from 38 to 332.9 μm. Data analysis yielded statistically significant differences between CEREC AC Bluecam and other scanners as well as between Zfx IntraScan and Lava C.O.S. Mean precision values ranged from 37.9 to 99.1 μm. Statistically significant differences were found between CEREC AC Bluecam and Lava C.O.S., CEREC AC Bluecam and iTero, Zfx Intra Scan and Lava C.O.S., and Zfx Intra Scan and iTero (p < 0.05).

Conclusions

Except for one intraoral scanner system, all tested systems showed a comparable level of accuracy for full-arch scans of prepared teeth. Further studies are needed to validate the accuracy of these scanners under clinical conditions.

Clinical relevance

Despite excellent accuracy in single-unit scans having been demonstrated, little is known about the accuracy of intraoral scanners in simultaneous scans of multiple abutments. Although most of the tested scanners showed comparable values, the results suggest that the inaccuracies of the obtained datasets may contribute to inaccuracies in the final restorations.

Nonmedical use of pain medications in dental patients.

Am J Drug Alcohol Abuse. 2014 Jul;40(4):312-316

Abstract

Abstract Background: Substance use is overrepresented in dental clinics that provide affordable care and dental clinics provide potential access to opioid analgesics. Research is needed to better understand prescription opioid misuse in this population. Objective: The purpose of this study was to assess the prevalence and correlates of the misuse of prescription opioids in adults seeking dental care from a low-cost dental training clinic. Methods: Patients were recruited from a university school's dentistry patient emergency and admission services clinic. Patients (n = 369) within the waiting area of the clinic completed a self-report questionnaire about their nonmedical use of prescription pain medications, medication diversion and use of substances. Results: Approximately 37.9% (140/369) of those who completed the study survey reported at least some nonmedical use of pain medications within the past 30 days. Use was associated with diversion of medication, and use of tobacco, marijuana, and sedatives. Conclusions: Within this sample from a dental clinic, nonmedical use of prescription pain medications was more common than in the general population. This suggests that dental clinics may be an appropriate setting for provider education and patient-based intervention strategies to reduce nonmedical use of pain medications.

Dentists should be at the forefront in the fight against sugar


The Lancet, Volume 383, Issue 9934, Page 2046, 14 June 2014
doi:10.1016/S0140-6736(14)60996-X
Sugar is the new tobacco.1 All efforts should be made to reduce sugar consumption. Education and governmental regulations alone cannot reduce consumption. A multisectorial approach is required using all possible routes: whole population, high-risk group, and targeted population approaches.2
Decreases in tobacco consumption have arguably flowed from the introduction of legislation (a whole population approach) and smoking cessation in clinics (a targeted population approach).3 We should consider the use of similar approaches to combat the threat posed by sugar.
Whole population approaches to control sugar consumption such as legislation and partnership with manufacturers have been attempted;4 however, few efforts have been made for a targeted population approach—eg, sugar cessation programmes at the individual level similar to smoking cessation.
Evidence supports the effectiveness of tobacco cessation services delivered via dental health-care practitioners. Tobacco cessation services delivered in public dental clinics have the potential to improve the health and wellbeing of millions of people globally.5 Dentists are well positioned to play an important part in reducing sugar consumption just as they do for smoking cessation.6
Dental caries is one of the earliest consequences of sugar consumption. Dentists have a strategic position to identify risk early in life and take preventive measure. Early detection of high sugar consumption in children is very important; children are the main targets of marketing campaigns for sweet products. Added sugar has found its way into almost all food, and the use of sugar as a means to calm, entertain, or reward children has become normalised, whereas sugar should be an occasional treat.
At the individual level, reducing sugar consumption can be particularly challenging. Estimation of individuals sugar intake can be difficult: food products labelling is often unclear.
Effectiveness, cost-effectiveness, and feasibility of sugar cessation programmes in dental clinics need to be established, and more reasearch is needed. According to the Healthy lives, healthy peoplereport from the Department of Health, if sugar consumption could be reduced by 30% within the next 5 years, the obesity epidemic could be stopped and the benefits for individuals and countries could be enormous. According to the Tackling obesities: future choices projectreport, the obesity epidemic costs the UK £5 billion a year, potentially rising to £50 billion by 2050.8 Therefore, it is crucial to use dentists' strategic position to help controlling sugar consumption as a targeted population approach from early childhood to later in life.

Approximal caries increment in adolescents in a low caries prevalence area in Sweden after a 3.5-year school-based fluoride varnish programme with Bifluorid 12 and Duraphat

Article first published online: 28 MAY 2014
DOI: 10.1111/cdoe.12108

 

Abstract

Objectives

To evaluate approximal caries increment among 12- to 16-year-olds in a low caries prevalence area in Sweden after a 3.5-year school-based fluoride (F) varnish programme with Bifluorid 12 and Duraphat.

Methods

The design was a RCT study with 1365 adolescents, divided into following four groups: Group 1 Bifluorid 12 two applications/year; Group 2 Duraphat two applications/year; Group 3 Bifluorid 12 four applications/year and Group 4 no F varnish at school. 1143 children (84%) completed the study. Approximal caries was registered on bitewing radiographs.

Results

There were no statistically significant differences in caries prevalence among the groups either at baseline or after 3.5 years . The caries increment for Group 1 was 1.34 ± 2.99 (mean ± SD), 1.24 ± 2.84 for Group 2, 1.07 ± 2.66 for Group 3 and 1.25 ± 2.75 for Group 4, with no statically significant differences either between Bifluorid 12 and Duraphat with the same frequency of F varnish applications or between the F groups and the control group.

Conclusions

In an area with low caries prevalence in Sweden, the supplementary caries-preventive effect of school-based F varnish applications, to regular use of F toothpaste at home and to regular caries prevention given at the Public Dental Clinics, appears to be nonsignificant regarding approximal caries increment.

Osteopenic consequences of botulinum toxin injections in the masticatory muscles: a pilot study

Cover image for Vol. 41 Issue 6

Early View (Online Version of Record published before inclusion in an issue)

Summary

Patients with temporomandibular muscle and joint disorder (TMJD) increasingly seek and receive treatment for their pain with botulinum toxin (BoNTA; botulinum toxin A). Used intramuscularly in therapeutic doses, it produces localised paresis. Such paresis creates risk of reduced bone mineral density, or ‘disuse osteopenia’. Animal studies have frequently used BoNTA as a model of paralysis to induce bone changes within short periods. Osteopenic effects can be enduring in animals but have yet to be studied in humans. This is the first study in humans to examine bone-related consequences of BoNTA injections in the masticatory muscles, comparing oral and maxillofacial radiologists’ ratings of trabecular bone patterns in the condyles of patients with TMJD exposed to multiple masticatory muscle injection sessions with BoNTA to a sample of patients with TMJD unexposed to masticatory muscle injections with BoNTA. Cone-beam computed tomography (CBCT)-derived images of bilateral condyles were evaluated in seven patients with TMJD receiving 2+ recent BoNTA treatment sessions for facial pain and nine demographically matched patients with TMJD not receiving BoNTA treatment. Two oral and maxillofacial radiologists evaluated CBCT images for evidence of trabecular changes consistent with osteopenia. Both evaluators noted decreased density in all participants exposed to BoNTA and in none of the unexposed participants (P < 0·001). No other abnormalities associated with reduced loading were detected. These findings need replication in a larger sample and over a longer time period, to ensure safety of patients with TMJD receiving multiple BoNTA injections for their pain.

Sealing versus partial caries removal in primary molars: a randomized clinical trial

BMC Oral Health 2014, 14:58  doi:10.1186/1472-6831-14-58
Published: 28 May 2014

Abstract (provisional)

Background

The resin-based pit and fissure sealant is considered a successful tool in caries prevention, however there is a growing evidence of its use in controlling already established caries in posterior teeth. The aim of this clinical trial is to verify the efficacy of pit and fissure sealants in arresting dentinal caries lesions compared to partial excavation and restorative treatment in primary molar teeth.

Methods

Thirty six patients with occlusal cavitated primary molar reaching outer half of dentin were selected. The patients were randomly allocated into two groups: sealant application (experimental group - n = 17) and restoration with composite resin (control group - n = 19). Clinical and radiograph evaluation were performed after 6, 12 and 18 months. The chi-square test was used to verify the distribution of characteristics variables of the sample among the groups. The survival rate of treatments was evaluated using Kaplan-Meier survival and log-rank test. Fisher's Exact and logistic regression tests were calculated in each evaluation period (alpha = 5%).

Results

The control group showed significantly better clinical survival after 18 months (p = 0.0025). In both groups, no caries progression was registered on the radiographic evaluations.

Conclusions

Sealing had similar efficacy in the arrestment of caries progression of cavitated occlusal lesions compared to partial excavation of the lesions, even though the frequency of re-treatments was significantly higher in sealed lesions.

Oral health conditions and cognitive functioning in middle and later adulthood

BMC Oral Health 2014, 14:70  doi:10.1186/1472-6831-14-70
Published: 13 June 2014

Abstract (provisional)

Background

The purpose of the present study was to examine the impact of oral health conditions on cognitive functioning on basis of data samples from several European countries.

Methods

Secondary analyses were conducted of data from wave 2 of the Survey of Health, Ageing, and Retirement in Europe (SHARE) which includes 14 European countries and is intended to be representative of each country's middle and later adulthood population. Information on word recall, verbal fluency, and numeracy as well as information on chewing ability and denture wearing status was available for a total of 28,693 persons aged 50+. Multivariate regression analysis was used to detect influences of oral health parameters on cognitive functioning (p < 0.05).

Results

Persons with good chewing ability or without dentures had significantly better word recall, verbal fluency, and numeracy skills than persons with chewing impairment or with dentures. The observed patterns of parameter estimates imply differential oral health impacts on numeracy compared to word recall and verbal fluency.

Conclusions

The present study provides novel large-scale epidemiological evidence supportive of an association between oral health and cognitive functioning. Future research should intend to verify the precise causal links between oral health conditions, various cognitive dimensions, and their neural correlates.

Effect of green tea extract and mouthwash without alcohol on Candida albicans biofilm on acrylic resin

Interesting how tea can effect denture acrylic MJ

Gerodontology 2014; doi:10.1111/ger.12132 Effect of green tea extract and mouthwash without alcohol on Candida albicans biofilm on acrylic resin

Objective

To evaluate the effect of aqueous extract of green tea and the oral antiseptic without alcohol, on Candida albicans biofilm formation to heat-curing acrylic resin plates.

Background

Candida is associated with oral candidiasis in poorly cleaned dentures.

Material and methods

Standardised specimens of heat-cured (Conv; n = 30) or microwave-cured acrylic resin (Mw; n = 30) were obtained and divided into six groups (n = 10): G1 = Conv resin and green tea aqueous extract, G2 = Conv resin and mouthwash, G3 = control of Conv resin, G4 = Mw resin and green tea aqueous extract, G5 = Mw resin and mouthwash and G6 = control of Mw-cured resin. The specimens were contaminated with 10 ml of Sabouraud dextrose broth inoculated with 0.1 ml of standard suspension containing 1 × 106 cells/ml of C. albicans and incubated for 24 h at 37°C. After this period, they were immersed in the aqueous extract or in mouthwash for 15 min. The control groups were treated with sterile distilled water. Aliquots of 0.1 ml were plated on Sabouraud dextrose agar and incubated at 37°C for 24 h. The numbers of colony-forming units per test specimen (CFU/TS) were calculated, and the results statistically analysed by two-way anova and Tukey's tests (5%).

Results

Statistically significant difference was observed for the aqueous extract groups (G1; 33.65%) and mouthwash (G2; 17.06%), when compared to control (G3; 100%), for Conv resin. For the Mw resin, there was significant difference between mouthwash (G5; 43.16%) and control (G6; 100%).

Conclusion

The aqueous extract of green tea and mouthwash led to a reduction in the number of viable fungal cells in biofilm formed on acrylic resin.

NYU College of Dentistry and University of California San Francisco Researchers Develop a Framework for Monitoring Oral Cancer Development, Progression and Recurrence




Dr. Brian Schmidt and Dr. Donna Albertson and their team look at shifts in the composition of the oral microbiome, to potentially be promoters or causes of oral cancer

Each year, approximately 22,000 Americans are diagnosed with oral cancer. The five-year survival rate of 40% in the U.S. is one of the lowest of the major cancers, and it has not improved in the past 40 years. More people die each year in the U.S. from oral cancer than from melanoma, cervical, or ovarian cancer. Worldwide, the incidence of oral cancer is increasing, particularly among young people and women, with an estimated 350,000 – 400,000 new cases diagnosed each year.

“The major risk factors, tobacco and alcohol use, alone cannot explain the changes in incidence, because oral cancer also commonly occurs in patients without a history of tobacco or alcohol exposure,” said Dr. Brian Schmidt, professor of oral and maxillofacial surgery and director of the Bluestone Center for Clinical Research at the NYU College of Dentistry (NYUCD).

Changes in the microbial community are commonly associated with dental diseases such as periodontal disease, which is most likely a poly-microbial disease characterized by outgrowth of certain pathologic organisms, and chronic periodontitis has been reported to be a risk factor for oral premalignant lesions and cancers.

“We know that other cancers, including gallbladder, colon, lung and prostate, have been associated with particular bacterial infections, so we hypothesized that shifts in the composition of the normal oral cavity microbiome could be promoters or causes of oral cancer,” said Dr. Albertson.

Drs. Schmidt and Albertson and their team profiled cancers and anatomically matched contralateral normal tissue from the same patient by sequencing 16S rDNA hypervariable region amplicons. The team’s findings, “Changes in abundance of oral microbiota associated with oral cancer,” published on-line in the journal POLS ONE (June 2, 2014), begin to develop a framework for exploiting the oral microbiome for monitoring oral cancer development, progression and recurrence.

In cancer samples from both a discovery (n=5) and a subsequent confirmation cohort (n=10), abundance of Firmicutes (especially Streptococcus) and Actinobacteria (especially Rothia) was significantly decreased relative to contralateral normal samples from the same patient. Significant decreases in abundance of these phyla were observed for pre-cancers, but not when comparing samples from contralateral sites (tongue and floor of mouth) from healthy individuals. Using differences in abundance of the genera Actinomyces, Rothia, Streptococcus and Fusobacterium, the team was able to separate most cancer samples from pre-cancer and normal samples.

“The oral cavity offers a relatively unique opportunity to screen at risk individuals for (oral) cancer, because the lesions can be seen, and as we found, the shift in the microbiome of the cancer and pre‑cancer lesions compared to anatomically matched clinically normal tissue from the same individual can be detected in non‑invasively collected swab samples.” said Dr. Schmidt.

Non-invasively sampling the microbiome of oral lesions and corresponding normal tissue opens the possibility to not only detect cancer‑associated changes at one time point, but the relative stability of the adult oral microbiome also offers the opportunity to monitor shifts in bacterial communities over time.

“Here we observed changes in the microbiome, which, in future larger studies, may be confirmed as a potential biomarker of oral cancers or pre‑cancers, and may even have utility to discriminate patients with lymph node metastases,” notes Dr. Albertson. “In addition, there are other challenges in clinical management of oral cancers that would benefit from better diagnostic tools.”

Oral cancer patients are also at risk of second primary cancers and recurrences. The microbiome may provide signatures that can be used as a biomarker for monitoring field changes associated with the high rate of second primary oral cancers and recurrences. The team also notes the possibility of medically modulating the oral microbiome for treatment of oral pre-cancers and damaged fields (field cancerization).

Effects of root surface debridement using Er:YAG Laser versus ultrasonic scaling – a SEM study

Abstract

Article first published online: 28 MAY 2014
DOI: 10.1111/idh.12074

 

Objective

Despite promising results of Er:YAG laser in periodontal debridement, to date there is no consensus about the ideal settings for clinical use. This experimental clinical trial aimed to determine the effects of debridement using Er:YAG laser and to compare with ultrasonic treatment.

Materials and methods

Sixty-four teeth were divided into two in vivo and in vitro subgroups. Each tooth received ultrasonic treatment on one side and Er:YAG laser debridement at either 60, 100, 160 or 250 mJ pulse−1 and at 10 Hz on the other side on a random basis. All samples were morphologically analyzed afterwards under scanning electron microscope for surface changes and dentinal tubules exposure. Treatment duration (d) was also recorded.

Results

Laser debridement produced an irregular, rough and flaky surface free of carbonization or meltdown while ultrasound produced a relatively smoother surface. The number of exposed dentinal tubules (n) followed an energy-dependent trend. The number of exposed tubules among the in vivo laser groups was n 60 mJ = n 100 mJ < n 160 mJ < n 250 mJ (P < 0.001). Also 160 and 250 mJ lasers led to significantly more dentinal exposure than ultrasound under in vivo condition. Within the in vitro laser groups, dentinal tubules exposure was n 60 mJ < n 100 mJ < n 160 mJ < n 250 mJ (P ≤ 0.0015). Furthermore, in vitro laser treatments at 100, 160 and 250 mJ led to significantly more dentinal denudation than ultrasound. Treatment duration (d) for the in vivo groups was d 60 mJ > d 100 mJ > d Ultrasound = d 160 mJ > d 250 mJ (P ≤ 0.046), while for the in vitro groups it was d 60 mJ > d 100 mJ = d Ultrasound = d 160 mJ >d 250 mJ (P ≤ 0.046).

Conclusions

Due to excessive treatment duration and surface damage, Er:YAG laser debridement at 60 and 250 mJ pulse−1, respectively, is not appropriate for clinical use. Although laser debridement at 100 and 160 mJ pulse−1 seems more suitable for clinical application, compared to ultrasound the former is more time-consuming and the latter is more aggressive. Using a feedback device or lower pulse energies are recommended when using laser in closed field.

An investigation of risk factors associated with tooth surface loss: a pilot study

Article first published online: 30 MAY 2014
DOI: 10.1111/joor.12186

 

Summary

Few prospective studies have investigated risk factors associated with severe tooth surface loss. This case–control study assessed the possible association between medical history, diet, psychological profile and salivary pH and flow [Delongis 1982, Johansson 1993] with the incidence of severe tooth surface loss. A total of 80 subjects (40 cases and 40 age- and gender-matched controls) aged 25–85 years were recruited. Cases were subjects with severe tooth surface loss, and controls with mild tooth surface loss. Conditional logistic regression analysis estimated the odds of severe tooth surface loss to be 15·4 times higher for those with cardiovascular disease and 16 times for gastrointestinal disturbances. Most domains of the psychological profile were associated with elevated risk of severe tooth surface loss, particularly the effects of finance and health. Recreational drug use and prescription medications were also associated with severe tooth surface loss. There was no association between salivary flow and severe tooth surface loss. Although not statistically significant, the pH was slightly lower in the severe tooth surface loss group.

Glass ionomer ART sealant and fluoride-releasing resin sealant in fissure caries prevention - results from a randomized clinical trial

BMC Oral Health 2014, 14:54  doi:10.1186/1472-6831-14-54
Published: 19 May 2014

Abstract (provisional)

Background

The relative performance of ART sealant and fluoride-releasing resin sealant in preventing fissure caries in permanent molars was compared in a randomized clinical trial conducted in southern China (ClinicalTrials.gov NCT01829334).

Methods

After obtaining ethical approval, healthy schoolchildren who had permanent first molars with occlusal fissures which were sound but deep or presented with only incipient caries were recruited for the study. Included molars were randomly allocated into one of four parallel study groups in units of left/right teeth per mouth. Two of the four groups adopted the methods of ART or fluoride-releasing resin sealant placement while the other two groups adopted the topical fluoride application methods. Fissure status of the molars in each group was evaluated every 6 months. Development of dentine caries and sealant retention over 24 months in the molars in the two sealant-using groups was compared in this report. Outcome on cost-effectiveness of all four groups over 36 months will be reported elsewhere.

Results

At baseline, a total of 280 children (383 molars) with mean age 7.8 years were involved for the two sealant groups. After 24 months, 261 children (357 molars) were followed. Proportions of molars with dentine caries were 7.3% and 3.9% in the ART sealant and fluoride-releasing resin sealant groups, respectively (chi-square test, p = 0.171). Life-table survival analysis showed that sealant retention (full and partial) rate over 24 months for the resin sealant (73%) was significantly higher than that (50%) for the ART sealant (p < 0.001). Molar survival (no development of dentine caries) rates in the ART sealant (93%) and fluoride-releasing resin sealant (96%) groups were not significantly different (p = 0.169). Multilevel logistic regression (GEE modeling) accounting for the effects of data clustering and confounding factors confirmed this finding.

Conclusions

Though the retention of fluoride-releasing resin sealant was better than that of the ART sealant, their effectiveness in preventing fissure caries in permanent molars did not differ significantly over 24 months. ART sealants could be a good alternative when and where resources for resin sealant placement are not readily available.

Patti DiGangi, RDH and Christine Taxin Collaborate on Second Installment of DentalCodeology Mini-Book Series

DentalCodeology: Jump Start Diagnostic Coding
Now Available BOGO with both Print and Digital formats

Addison, IL – May 30, 2014 –  Patti DiGangi, RDH, BS, a prominent dental hygiene thought leader, recently collaborated with dental industry insurance coding expert Christine Taxin on the second installment of DiGangi’s continuing DentalCodeology mini-book series.

DentalCodeology: Jump Start Diagnostic Coding, pocket-size book is a follow-up to DentalCodeology: More than Pocket Change, which was introduced at the 2013 RDH Under One Roof Meeting. The DentalCodeology book series is designed to be on the front lines of patient care, whether in its hardcopy, pocket-sized book, or the downloadable digital version for smartphones.

The focus of the latest booklet is determining dental-medical necessity that can profitability be used immediately for cross-coding which will soon become a necessity with the rapid emergence of electronic health records (EHR) and the increased scientific validation of oral-systemic health links.

According to Patti DiGangi, “EHR is not on the distant horizon – it is here today! It’s the technology platform that will enable dentists, physicians and other healthcare professionals to effectively share information and closely collaborate to provide optimal patient care. As dentistry moves from a treatment-centered model to a diagnostic-centered model, consistent and accurate coding will be vital to ensure interoperability with the rest of healthcare industry.”

 “If EHR is the communications network, then insurance coding is the language used between its healthcare provider points,” explained Christine Taxin. “The entire dental team needs to achieve dental and medical cross-coding proficiency in order to communicate and collaborate effectively with their medical colleagues for the benefit of their mutual patients.”

DentalCodeology: Jump Start Diagnostic Coding not only provides the basics of dental-medical cross-coding, it also demonstrates how to use it to develop effective letters for explaining the medical necessity of dental treatment, forging closer working relationships with physicians and expediting insurance reimbursement.

In addition to their book collaboration, DiGangi and Taxin have developed corresponding 1and 2 day workshops and webinars for DentalCodeology: Jump Start Diagnostic Coding. The two thought leaders will also be conducting a book signing at the upcoming Speaking and Consulting Network Meeting on June 5th-7th in Tampa Bay Florida.

DiGangi will continue her DentalCodeology series with What’s the Evidence and How to Say It with Liz Neis, Behind the Coding Curtain with Teresa Duncan and Oral-Systemic Reality Coding. The books will also have a corresponding web seminar component as well.
