The influence of fixed orthodontic appliances on masticatory and swallowing threshold performances

Magalhães, I. B., Pereira, L. J., Andrade, A. S., Gouvea, D. B. and Gameiro, G. H. (2014), The influence of fixed orthodontic appliances on masticatory and swallowing threshold performances. Journal of Oral Rehabilitation. doi: 10.1111/joor.12218


To test the hypothesis that treatment with orthodontic appliances disturbs masticatory and swallowing performances. Twenty-seven subjects with malocclusions requiring orthodontic treatment were included in this prospective study. The masticatory and swallowing performances were evaluated at five different times: before bracket placement (T0), immediately after archwire placement (T1), 48 h after archwire placement (T2), 30 days after archwire placement (T3) and 3 months after the initial appointment (T4). Masticatory performance was determined by the median particle sizes for the Optocal test food after 15 chewing strokes, and the swallowing thresholds were registered for both the test food and a natural food (peanuts). Pain during mastication was evaluated using a 100-mm visual analogue scale. Masticatory performance was significantly reduced at T2, at which time patients reported the highest pain values. The time spent to the first swallow was increased at T2 for the natural food but not for the test food. The values for pain, masticatory and swallowing performances at T3 and T4 were similar to those at T0. Orthodontic patient masticatory function is only reduced during the period of higher pain experience, which could also disrupt the deglutition of harder foods. However, neither mastication nor deglutition processes were disturbed by orthodontic appliances in long-term treatment.

The LED IC100’s optimal resolution ensures crisp, clear images that capture every minute detail.
  • Diagnostic flexibility: The LED IC100 features two LED lights to minimize the reflection of light on tooth surfaces. The aspheric lens prevents image distortion and works hand-in-hand with the intraoral camera’s auto-focus technology to provide sharper images. Plus, the intraoral camera features an automatic on/off system that operates in conjunction with any imaging software, so there are fewer steps required for the LED IC100 to capture an image. 
  • Direct USB plug-in: LED Dental’s first intraoral camera plugs directly into any computer via a USB 2.0 connection, eliminating the need for a dock or hub. The LED IC100 also acts on a “plug-and-play” design, which is ideal for multi-chair practices.
  • Ergonomic design: The LED IC100 is designed with both practitioners and patients in mind. The intraoral camera’s slim head allows for faster, easier and more comfortable movement within patients’ mouths, while its lightweight body prevents user fatigue.
  • Open-architecture workflow: The LED IC100 has an open-architecture design for streamlined integration with third-party software and imaging solutions. The intraoral camera can be implemented into a practice seamlessly, further streamlining workflow. 

“As most clinicians have experienced, visual evidence is a key selling point when informing patients of their diagnosis so they understand why treatment is needed. Having a high-quality, reliable intraoral camera is a lifeline for any practice,” said Lamar Roberts, president of LED Dental. “We’re in the business of providing practitioners with the diagnostic tools they need to succeed – that’s why we’ve added the LED IC100 to our growing portfolio.”

Short implant in limited bone volume

Nisand, D. and Renouard, F. (2014), Short implant in limited bone volume. Periodontology 2000, 66: 72–96. doi: 10.1111/prd.12053


Rehabilitation of severely resorbed jaws with dental implants remains a surgical and prosthetic challenge for clinicians. The purpose of this review was to evaluate the available data on short-length implants and discuss their indications and limitations in daily clinical practice. A structured review of MEDLINE and a manual search were conducted. Thirty-two case series devoted to short-length implants, 14 reviews and 3 randomized controlled trials were identified. Of this group of papers, we can conclude that short-length implants can be successfully used to support single and multiple fixed reconstructions in posterior atrophied jaws, even in those with increased crown-to-implant ratios. The use of short-length implants allows treatment of patients who are unable to undergo complex surgical techniques for medical, anatomic or financial reasons. Moreover, the use of short-length implants in daily clinical practice reduces the need for complex surgeries, thus reducing morbidity, cost and treatment time. The use of short implants promotes the new concept of stress-minimizing surgery, allowing the surgeon to focus more on the correct three-dimensional positioning of the implant.

comparison of four gutta-percha filling techniques in simulated C-shaped canals

DOI: 10.1111/iej.12371



To compare four gutta-percha filling techniques in simulated C-shaped canals based on filling quality at three cross-sectional levels, filling time and the apical extrusion of gutta-percha.


Forty resin simulated C-shaped canals were constructed and filled using one of four techniques; cold lateral compaction (LC), ultrasonic compaction (UC), single cone with injectable gutta-percha (Obtura II) (IT) and core-carrier (Thermafil®) (CC). Cross-sections were made at 1 (L1), 3 (L3), and 6 (L6) mm from the canal terminus. Areas of gutta-percha, sealer and voids in each cross-section were measured using an image analysis system. Data were analysed using a univariate general linear model and post hoc test (Dunnett's T3). Data of obturation time was evaluated using the Bonferroni post-hoc test


CC had more gutta-percha and less sealer compared to IT at L1 (P<0 .05="" at="" cc="" em="" gutta-percha="" had="" lc="" less="" level="" marginally="" significantly="" than="" this="">P

At level 3 mm, significantly more gutta-percha and less sealer were present in IT compared to LC (P <0 .05="" and="" at="" both="" cc="" difference="" em="" for="" four="" in="" it="" l6.="" lc="" longer="" minutes="" no="" quality="" showed="" techniques="" than="" the="" three="" time="" times="" uc="" was="" whereas="">P <0 .001="" apical="" different="" extrusion="" finally="" four="" gutta-percha.="" in="" not="" occurrence="" of="" p="" techniques="" the="" were="">


The core-carrier technique was the most effective technique in the filling of this simulated C-shaped canal.

Dental cone beam computed tomography: justification for use in planning oral implant placement

Jacobs, R. and Quirynen, M. (2014), Dental cone beam computed tomography: justification for use in planning oral implant placement. Periodontology 2000, 66: 203–213. doi: 10.1111/prd.12051


Intra-oral and panoramic radiographs are most frequently used in oral health care. Yet, the inherent nature of jaws and teeth renders three-dimensional diagnosis essential, especially in relation to oral surgery. Nowadays, this can be accomplished by dental cone beam computed tomography, which provides high-quality images at low radiation doses and low costs. Nonetheless, the effective dose ranges of cone beam computed tomography machines may easily vary from 10 to 1000 μSv, this being equivalent to two to 200 panoramic radiographs, even for similar presurgical indications. Moreover, the diagnostic image quality varies massively among available machines and parameter settings. Apart from the radiodiagnostic possibilities, dental cone beam computed tomography may offer a vast therapeutic potential, including opportunities for surgical guidance and further prosthetic rehabilitation via computer-aided design/computer-aided manufacturing solutions. These additional options may definitely explain part of the success of cone beam computed tomography for oral implant placement. In conclusion, dental cone beam computed tomography imaging could be justified for oral implant-related diagnosis, planning and transfer to surgical and further prosthetic treatment, but guidelines for justification and cone beam computed tomography optimization remain mandatory.
