The Effect of Disinfection with Chlorhexidine on the Shear Bond Strength of Equia Resin-Modified Glass Ionomer Cement to Dentin in Permanent Teeth after Two Thermocycling Protocols


Abstract


Statement of the Problem: There are some concerns regarding the effect of chlorhexidine (CHX) applied for cavity disinfection on the bond strength of adhesive restorations to dentin.
Purpose: This study sought to assess the effect of CHX on the shear bond strength (SBS) of Equia resin-modified glass ionomer cement (RMGIC) to dentin in permanent teeth.
Materials and Method: In this experimental study, the buccal surface of 84 freshly extracted human premolars was ground to expose the flat dentin. The samples were randomly assigned to four groups (n=21). The steps were as following in the group Ia: conditioning, Equia RMGIC, 500 thermal cycles; group Ib: conditioning, Equia RMGIC, 6000 thermal cycles; group IIa: conditioning, CHX, Equia RMGIC, 500 thermal cycles, and group IIb: conditioning, CHX, Equia RMGIC, and 6000 thermal cycles. Twenty samples from each group were subjected to SBS test and one sample was inspected under a scanning electron microscope. Data were analyzed using two-way ANOVA and t-test.
Results: The SBS was significantly different among the groups (p= 0.007). The groups subjected to 500 thermal cycles showed significantly higher SBS to dentin when they were treated with CHX (p= 0.000). There was no significant difference between samples thermocycled for 6000 cycles with and without application of CHX (p= 0.269). The SBS in the groups that were thermocycled for 6000 cycles (Ib and IIb) was lower than those thermocycled for 500 cycles (Ia and IIa). This difference between IIa and IIb was statistically significant (p= 0.007).
Conclusion: Chlorhexidine can positively affect the short term SBS of Equia RMGIC to dentin.

The Risk Factors in Early Failure of Dental Implants: a Retrospective Study

Abstract


Statement of the Problem: Despite the low failure rate of dental implants, recognition of the risk factors can enhance the predictability of failure.
Purpose: The aim of this study was to evaluate the risk factors for early implant failure.
Materials and Method: This retrospective cohort study was conducted on two groups of patients, the patients with a failed implant before loading and those without a failed implant. Age, gender, implant type, implant surface, implant length, bone type, type of surgery (one- or two-stage) and immediate (fresh socket) or delayed placement of implant were the variables to be assessed in this study.
Results: Out of the 1,093 evaluated implants, 73 cases (6.68%) failed in early stages. The two groups were significantly different in terms of implant surface, fresh socket placement, prophylactic use of antibiotics, and bone density (p< 0.05). Age, gender, implant height, implant type (cylindrical or tapered) and one-stage or two-stage placement were not significantly different between the two groups (p> 0.05).
Conclusion: It seems that prophylactic antibiotic therapy, implant surface, bone density and placement in fresh extraction socket may contribute to dental implant failure.

Effect of Simplifying Drilling Technique on Heat Generation During Osteotomy Preparation for Dental Implant


doi: 10.1097/ID.0000000000000692
Basic and Clinical Research
Objectives: To test the hypothesis that there would be no difference in heat production by reducing the number of drills during the implant site preparation relative to conventional drilling sequence.
Methods: A total of 120 implant site preparations with 3 different diameters (3.6, 4.3, and 4.6 mm) were performed on bovine ribs. Within the same diameter group, half of the preparations were performed by a simplified drilling procedure (pilot drill + final diameter drill) and other half using the conventional drilling protocol (pilot drill followed by graduated series of drills to widen the site). Heat production by different drilling techniques was evaluated by measuring the bone temperature using k-type thermocouple and a sensitive thermometer before and after each drill.
Results: Mean for maximum temperature increase during site preparation of the 3.6, 4.3, and 4.6-mm implants was 2.45, 2.60, and 2.95° when the site was prepared by the simplified procedure, whereas it was 2.85, 3.10, and 3.60° for the sites prepared by the conventional technique, respectively. No significant difference in temperature increase was found when implants of the 3 different diameters were prepared either by the conventional or simplified drilling procedure.
Conclusions: The simplified drilling technique produced similar amount of heat comparable to the conventional technique that proved the initial hypothesis.

doi: 10.1097/ID.0000000000000635
Basic and Clinical Research
Purpose: To compare the long-term clinical and radiographic outcomes between immediate loading (IL) and conventional loading of implants placed immediately in fresh extraction sockets.
Materials and Methods: Demographic data, implant details, and periapical radiographs of patients were collected. The long-term marginal bone level remodeling and implant survival rate were calculated.
Results: Twenty-one patients (mean age 52.55 ± 14.61 years) with 35 implants immediately inserted into postextraction sites (22 immediate loaded and 13 delayed loaded) were analyzed. The mean follow-up duration was 6 years (range 2–11 years). The implant cumulative survival rate was 96.5%. At the longest follow-up, the mean crestal bone level averaged 0.144 ± 0.705 for IL and 0.161 ± 0.877 for delayed loading, respectively. The mean implant aesthetic score was 7.
Conclusions: IL does not negatively influence the long-term prognosis of implants inserted into fresh extraction sockets.

Management of the Maxillary Diastema by Various Dental Specialties

 

Abstract

Purpose

There is considerable controversy in the literature concerning the indications for frenectomy for treating a maxillary diastema, as well as timing of the procedure. The purpose of this study was to survey pediatric dentists, orthodontists and oral and maxillofacial surgeons regarding their opinion about this matter in an attempt to develop a consensus.

Materials and Methods

An anonymous 7-item electronic questionnaire was sent to members of the American Academy of Pediatric Dentists, the American Association of Orthodontists and the American Association of Oral and Maxillofacial Surgeons asking about etiology of the maxillary diastema, its diagnosis, and treatment.

Results

Although there was not agreement among the oral and maxillofacial surgeons regarding timing of frenectomy and when the diastema should be closed, the pediatric dentists and orthodontists generally agreed that frenectomy should not be done before the permanent canines are erupted and that the operation should follow orthodontic closure of the space.

Conclusion

Although there was no complete consensus among the 3 groups, a logical treatment approach for the maxillary diastema is proposed.

Accuracy of extraoral bite-wing radiography in detecting proximal caries and crestal bone loss.

J Am Dent Assoc. 2017 Oct 28. pii: S0002-8177(17)30788-2. doi: 10.1016/j.adaj.2017.08.032. [Epub ahead of print]

Abstract

BACKGROUND:

Extraoral bite-wing (EB) radiography is an imaging technology used in dentistry. The authors conducted an in vivo study comparing the accuracy of intraoral bitewing (IB) radiographs and EB radiographs for proximal caries and bone loss diagnosis.

METHODS:

The authors recruited 116 patients who received IB radiographs to receive EB radiographs. The 5 calibrated authors made a consensus radiographic diagnosis of proximal caries and crestal bone loss. For this study, they assumed IB radiographs as the criterion standard. Next, they obtained EB radiographs for the 116 patients and calculated sensitivity, specificity, and false-positive rates against each patient's IB radiograph.

RESULTS:

The patients' EB radiographs revealed a significantly greater number of caries and crestal bone loss findings compared with their IB radiographs. The EB radiographs had a high to excellent sensitivity and moderate to low specificity of caries and crestal bone loss findings, respectively. Considering IB radiographs to be the criterion standard, the false-positive rate for EB radiographs was moderate for caries and high for bone loss diagnosis.

CONCLUSIONS:

The EB radiographs, which generate fewer images of overlapping proximal surfaces, have the advantage of detecting more carious lesions and bone loss findings than the IB radiographs do, but with the disadvantage of more false-positive diagnoses. Further research is needed to evaluate if the false-positive findings represent true carious lesions and bone loss.

PRACTICAL IMPLICATIONS:

EB radiography is a promising technology, which has several advantages over traditional IB radiography. Clinicians should be aware of false-positive diagnosis of caries and bone loss with EB radiography.

Three-camera setup to record simultaneously standardized high-definition video for smile analysis


Introduction

Our objective was to develop a photographic setup that would simultaneously capture subjects' smiles from 3 views, both statically and dynamically, and develop a software to crop the produced video clip and slice the frames to study the smile at different stages.

Methods

Facial images were made of 96 subjects, aged 18 to 28 years, in natural head position using a standardized setup of 3 digital single lens reflex cameras, with a reference sticker (10 × 10 mm) on the forehead of each subject. To test the reproducibility of the setup, 1 operator took 3 images of all subjects on the same day and on 3 different days in a subset of 26 subjects.

Results

For the same-day observations, correlation coefficients varied between 0.87 and 0.93. For the observations on 3 different days, correlation coefficients were also high. The duplicate measurement error and the mean difference between measurements were small and not significant, pointing to good reliability.

Conclusions

This new technique to capture standardized high-definition video and still images simultaneously from 3 positions is a reliable and practical tool. The technique is easy to learn and implement in the orthodontic office.

Comparison of the effect of endodontic-periodontal combined lesion on the outcome of endodontic microsurgery with that of isolated endodontic lesion: survival analysis using propensity score analysis

Original Article

Abstract

Objectives

The purpose of this retrospective clinical study was to evaluate the effect of lesion types related to endodontic microsurgery on the clinical outcome.

Materials and methods

Patients who underwent endodontic microsurgery between March 2001 and March 2014 with a postoperative follow-up period of at least 1 year were included in the study. Survival analyses were conducted to compare the clinical outcomes between isolated endodontic lesion group (endo group) and endodontic-periodontal combined lesion group (endo-perio group) and to evaluate other clinical variables. To reduce the effect of selection bias in this study, the estimated propensity scores were used to match the cases of the endo group with those of the endo-perio group.

Results

Among the 414 eligible cases, the 83 cases in the endo-perio group were matched to 166 out of the 331 cases in the endo group based on propensity score matching (PSM). The cumulated success rates of the endo and endo-perio groups were 87.3 and 72.3%, respectively. The median success period of the endo-perio group was 12 years (95% CI: 5.507, 18.498). Lesion type was found to be significant according to both Log-rank test (P = 0.002) and Cox proportional hazard regression analysis (P = 0.001). Among the other clinical variables, sex (female or male), age, and tooth type (anterior, premolar, or molar) were determined to be significant in Cox regression analysis (P < 0.05).

Conclusion

Endodontic-periodontal combined lesions had a negative effect on the clinical outcome based on an analysis that utilized PSM, a useful statistical matching method for observational studies.

Clinical relevance

Lesion type is a significant predictor of the outcome of endodontic microsurgery.

Effects of low-level laser irradiation on the rate of orthodontic tooth movement and associated pain with self-ligating brackets



Introduction

The aim of this study was to evaluate the effect of low-level laser irradiation applied at 3-week intervals on orthodontic tooth movement and pain associated with orthodontic tooth movement using self-ligating brackets.

Methods

Twenty-two patients (11 male, 11 female; mean age, 19.8 ± 3.1 years) with Angle Class II Division 1 malocclusion were recruited for this split-mouth clinical trial; they required extraction of maxillary first premolars bilaterally. After leveling and alignment with self-ligating brackets (SmartClip SL3; 3M Unitek, St Paul, Minn), a 150-g force was applied to retract the canines bilaterally using 6-mm nickel-titanium closed-coil springs on 0.019 x 0.025-in stainless steel archwires. A gallium-aluminum-arsenic diode laser (iLas; Biolase, Irvine, Calif) with a wavelength of 940 nm in a continuous mode (energy density, 7.5 J/cm2/point; diameter of optical fiber tip, 0.04 cm2) was applied at 5 points buccally and palatally around the canine roots on the experimental side; the other side was designated as the placebo. Laser irradiation was applied at baseline and then repeated after 3 weeks for 2 more consecutive follow-up visits. Questionnaires based on the numeric rating scale were given to the patients to record their pain intensity for 1 week. Impressions were made at each visit before the application of irradiation at baseline and the 3 visits. Models were scanned with a CAD/CAM scanner (Planmeca, Helsinki, Finland).

Results

Canine retraction was significantly greater (1.60 ± 0.38 mm) on the experimental side compared with the placebo side (0.79 ± 0.35 mm) (P <0 .05="" 1.4="" 2.4="" after="" and="" application="" at="" compared="" day="" experimental="" first="" less="" llli="" nbsp="" of="" on="" only="" p="" pain="" placebo="" second="" side="" sides="" significantly="" the="" visit="" was="" with="">

Conclusions

Low-level laser irradiation applied at 3-week intervals can accelerate orthodontic tooth movement and reduce the pain associated with it.

Clinical survival of chair-side generated monolithic lithium disilicate crowns:10-year results

Original Article

Abstract

Objectives

Nowadays, all-ceramic materials are routinely used within the treatment of patients in dentistry. The objective of this prospective clinical trial was the evaluation of chair-side generated monolithic lithium disilicate crowns after 10 years.

Materials and methods

Forty-one posterior full contour crowns made of lithium disilicate ceramics were inserted with a self-adhesive resin cement in 34 patients (20 university/14 private practice) using a chair-side CAD/CAM technique. One crown per patient was randomly selected for evaluation according to the modified US Public Health Service criteria.

Results

After a mean examination time of 10.1 years, 26 crowns were available for re-examination. Within the observation period, five failures occurred due to one crown fracture after 2.9 years, an abutment fracture after 6.0 years, one severe endodontic problem after 6.1 years, a root fracture after 7.0 years, and a replacement of one crown caused by a carious lesion after 10 years. Complications occurred as retention loss of one crown, two carious lesions, and a change in sensibility perception of two abutment teeth. All events were associated with molars.

MouthWatch, LLC Showcasing Teledentistry for Urban and Suburban Private Practices During the Greater New York Dental Meeting




Metuchen, NJ – November 13, 2017 – MouthWatch, LLC a leader in intraoral imaging, digital case presentation and teledentistry solutions, will be showcasing private practice applications of its TeleDent™ teledentistry platform at booth #3430 during the Greater New York Dental Meeting.

According to MouthWatch CEO Brant Herman, “For the past few years, our TeleDent™ all-in-one teledentistry platform has been proving itself on the front lines of public health and other innovative care delivery models of dentistry.  The Greater New York meeting is an ideal place to introduce TeleDent™ to private practice specialists and GP dentists from both urban and suburban areas. We’re looking forward to demonstrating the benefits of virtual collaboration and secure case data sharing.”

Herman says the cost-effectiveness and ease-of-use his company’s TeleDent™ platform make it well-suited for the following teledentistry applications:

·       Specialist/GP Collaboration – Teledentistry is a catalyst for collaborative care and increased referrals. The results include positive patient outcomes and reduced risk of failure in complex cases.

·       Dentist-Owned Hygiene Clinics –A full service dental office can be linked to remote hygiene clinics that the dentist also owns and operates.

·      DSO Resource Sharing – Teledentistry enables DSOs and groups to offer live or asynchronous consults with a rotating specialist no matter which location they are currently working in.

·       Dentist / Dental Lab Collaboration –  Dentists and dental lab operators can
share CBCT images, digital impression files and patient photos to increase case accuracy and ultimately ensure patient satisfaction. This capability can be especially valuable in treatment planning and completing complex restorative cases.

“Of course, we will continue to serve the public health sector and assist with improving access to and equity of care,” explained Herman. “At the same time, TeleDent™ provides unique business and clinical opportunities for private practices and DSOs in urban and suburban settings. It’s is an ideal way for these practices to implement teledentistry. Our mission is to transform and enhance the delivery of care throughout dentistry.”
