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



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.


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).


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


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.


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).


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="">


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



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.


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. The Kaplan-Meier analysis revealed a survival rate of 83.5% and a complication-free rate of 71.0% after 10 years.


Due to the small amount of technical complications and failures, the clinical performance of monolithic lithium disilicate crowns was completely satisfying.

Clinical relevance

The insertion of chair-side fabricated monolithic lithium disilicate crowns can be recommended for long-term use in the posterior region.

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.”
