Volume of sealer in the apical region of teeth filled by different techniques: a micro-CT analysis

Mon, 28 Mar 2016 13:22:58 +0100

Abstract The volume of sealer in the apical 1 mm of teeth filled using different techniques was evaluated by micro-commuted tomography (micro-CT). Sixty-four maxillary central incisors were prepared using NiTi rotary instruments. Teeth were randomly distributed into four groups according to root canal sealers (AH Plus, Endofill, Sealapex, and Sealer 26) and subdivided into two subgroups according to the filling techniques (active and passive lateral condensation; n = 8 each). Subsequently, teeth were examined using the 1174 SkyScan micro-CT device. Images were reconstructed using the NRecon software, and the sealer volume (mm3) in the apical region was analyzed using the two-way ANOVA and post-hoc Student–Newman–Keuls test (α = ٠.٠٥). The lowest volume of sealer was observed in tee...

Analysis of Interleukin 17A in periapical abscess and granuloma lesions

Mon, 28 Mar 2016 13:22:58 +0100

In conclusion, IL-17A was intensively expressed in periapical abscesses rich in neutrophils. The high percentage of IL-17A in these cases suggests the participation of this cytokine particularly in the acute stages of the inflammatory process of the periapical lesions.

Influence of different fillers on the properties of an experimental vinyl polysiloxane

Mon, 28 Mar 2016 13:22:58 +0100

Abstract The aim of the study was to evaluate the effect of the incorporation of different fillers on an experimental vinyl polysiloxane (VPS) at two different concentrations, 20% and 40%. Different fillers were added to an experimental VPS. The study was developed in two stages: (i) incorporation of fillers in different concentrations: (a) 20 wt% fillers, and (b) 40 wt%. The fillers were added to experimental VPS and mixed with a speed mixer; (ii) characterization of experimental VPS; after the base paste and catalyst paste were mixed, the experimental VPS was used to make specimens specifically for each test, which were stored at 23°C for 24 hours. The tests were designed according to the specific standardization for the analysis of tensile strength, detail reproduction, Shore A hardnes...



Effect of filling technique on the bond strength of methacrylate and silorane-based composite restorations

Mon, 28 Mar 2016 13:22:58 +0100

Abstract The bond strength of methacrylate (Z350, 3M ESPE) and silorane (P90, 3M ESPE) restorations, using different cavity filling techniques, was investigated. Cavities (6 × 3 × 3) in bovine teeth were filled using bulk, oblique, or horizontal increments. A push-out test was carried out after 24 h. Data were statistically analyzed (α = 5%). Methacrylate-based composites and the horizontal filling technique showed the highest bond strength values (10.2 ± 3.9, p < 0.05). Silorane-based composites showed no statistically significant differences regarding the filling techniques (p > 0.05). (Source: Brazilian Oral Research)



Breastfeeding, bottle feeding and risk of malocclusion in mixed and permanent dentitions: a systematic review

Mon, 28 Mar 2016 13:22:58 +0100

Abstract The aim of the present study was to search for scientific evidence concerning the association between breastfeeding and bottle feeding and risk of malocclusion in mixed and permanent dentitions. An electronic search was performed in eight databases up to February 2015.

The methodology of the included articles was evaluated using the Newcastle Ottawa scale. Out of the 817 identified citations, six studies fulfilled the eligibility criteria and were included in the systematic review. One study showed that children with mixed and permanent dentitions breastfed for more than 6 months presented g...



Fluoride rinse effect on retention of CaF2 formed on enamel/dentine by fluoride application

Mon, 28 Mar 2016 13:22:58 +0100

Abstract Calcium fluoride-like materials (“CaF2”) formed on dental surfaces after professional fluoride application are unstable in the oral environment but can be retained longer with a daily NaF mouthrinse. We tested the effect of twice daily 0.05% NaF rinses on the retention of “CaF2” formed on enamel and dentine after applying acidulated phosphate fluoride (APF). “CaF2” formed on enamel/dentine by APF application significantly decreased after exposure to artificial saliva and the 0.05% NaF rinse was ineffective to avoid this reduction. These findings suggest that the combination of APF and 0.05% NaF is not clinically relevant, either for caries or dental hypersensitivity. (Source: Brazilian Oral Research)

Test–retest reliability of a new technique with pressure algometry applied to teeth in healthy Chinese individuals

Mon, 28 Mar 2016 13:22:43 +0100

Pressure pain thresholds (PPTs) have been shown to be useful measures of mechanical pain sensitivity in deep tissues. However, clinical methods for measuring mechanical allodynia or hyperalgesia in teeth have not been reported. The aim of this study was to assess the reliability of PPTs in periodontal ligament of healthy Chinese participants. Twenty healthy young adults participated. Pressure pain thresholds were measured at six teeth and in two directions. The tests included three consecutive trials, in two separate sessions, which were performed on the first day by one examiner. After 1–3 wk, an identical protocol was carried out by two examiners, also in two separate sessions. There were no significant differences between repeated measures for all teeth. The PPTs had excellent reliabi...

Decreased expression of E‐cadherin by Porphyromonas gingivalis‐lipopolysaccharide attenuates epithelial barrier function

Sun, 27 Mar 2016 00:13:25 +0100

ConclusionThese results suggest that the decrease in E‐cad caused by P. gingivalis‐LPS leads to destruction of the epithelial barrier function in human gingival epithelial cells, and finally accelerates the inflammatory reaction under the barrier. Antioxidants, particularly vitamin E and l‐ascorbic acid 2‐phosphate magnesium salt, may restore the impaired function by scavenging ROS, which are related to the decrease in E‐cad expression by P. gingivalis‐LPS.

Keep the ones you’ve got

Thu, 24 Mar 2016 23:00:00 +0100

Teeth lost to disease, injury, or congenital tooth agenesis are often replaced by dental implants, with this option widely incorporated into everyday dental practice. As a result, patients have enjoyed major improvements in oral health, better function, better esthetics, and improved phonetics compared to previous outcomes. However, gathering research is exposing the adverse outcomes associated with implants. Among these are biological complications and the unpredictability of implant therapy. Is it time to revisit saving teeth as a viable option rather than simply placing implants? (Source: Dental Abstracts)



Taking evidence-based advice

Thu, 24 Mar 2016 23:00:00 +0100

Tension exists today between those who tout autonomy of thought and action as the highest good and those who seek to impose population-wide solutions to problems based on evidence from rigorous scientific investigation. Studies show that older Americans treated aggressively to control blood pressure to 120 mm Hg or less have a diminished risk of stroke and heart attack with no adverse risk of injury from falls caused by medication compared to those whose target blood pressure is 140 mm Hg. As a result, a lower blood pressure goal is appropriate for the majority of the population over age 50 years based on scientific evidence. (Source: Dental Abstracts)



Tricks to Saving Your Teeth and Your Wallet in the End

Thu, 24 Mar 2016 20:39:20 +0100

Dear Nurse Katz, I just graduated and I am trying to stay healthy and avoid going into medical debt. I was thinking about cutting out my dental care, but I have been told that it is just as important than seeing your primary car doctor, but insurance does not seem to cover a lot when it comes to dental care, and every time I go to the dentist, I come out with a huge bill. I want to keep my teeth until I am at least 70. What should I do? Matt Kansas City, MO Good for you for thinking ahead Matt! You should not cut out oral care all together due to the expense. Keep in mind that bad oral care today could potentially lead to expensive dentures when you are 70. In addition, many times, the condition of the mouth mimics the condition of the body as a whole.

Kanzow, Philipp / Wegehaupt, Florian J. / Attin, Thomas / Wiegand, AnnettePage 275 - 278The condition of dental erosion is defined as acid-related loss of tooth structure which does not involve microorganisms. Depending on the origin of the acid, extrinsic (usually caused by acids in food) and intrinsic (caused by endogenous acid) erosion can be distinguished. The presence and severity of erosive defects depend on various parameters such as nutrition, saliva, general diseases, and mechanical stress by abrasion and attrition. As an example, dietary habits which involve frequent intake of acidic food and beverages, occupational acid exposure, as well as certain drugs or diseases that affect saliva flow rate are accompanied by an increased risk of erosive dental hard tissue defects. By a thor...

Topical sulfasalazine for unresponsive oral lichen planus

Thu, 24 Mar 2016 15:15:54 +0100

Conclusion: Topical sulfasalazine should be considered when OLP does not respond to corticosteroid therapy. Furthermore, high concentrations of IL-1β and IL-8 in the saliva are useful indicators for the application of topical sulfasalazine in OLP patients refractory to steroid treatment.

Bisphosphonates and dental implants: A meta-analysis

Thu, 24 Mar 2016 15:15:54 +0100

Conclusion: The results of the present study cannot suggest that the insertion of dental implants in patients taking BPs affects the implant failure rates, due to a limited number of published studies, all characterized by a low level of specificity, and most of them dealing with a limited number of cases without a proper control group. Therefore, the real effect of BPs on the osseointegration and survival of dental implants is still not well established. (Source: Quintessence International)

Non‐antibacterial tetracycline formulations: host‐modulators in the treatment of periodontitis and relevant systemic diseases

Thu, 24 Mar 2016 15:14:55 +0100

Traditionally, the dental profession has primarily treated periodontitis using a mechanical/surgical, rather than a pharmaceutical, approach. However, based on experiments several decades ago which demonstrated that tetracyclines, unexpectedly, inhibit collagen‐ and bone‐destructive mammalian‐derived enzymes (e.g. the collagenases), and through non‐antibiotic mechanisms, the concept of host‐modulation therapy (HMT) was developed. Accordingly, two drug‐development strategies evolved: (i) the development of non‐antimicrobial formulations of doxycycline; and (ii) the chemical modification of tetracyclines to eliminate their antibiotic activity but retain (or even enhance) their anti‐collagenase properties. Regarding the latter, these chemically modified tetracyclines (CMTs) sh...

Effective strategies to motivate nursing home residents in oral healthcare and to prevent or reduce responsive behaviours to oral healthcare: a systematic review protocol

Wed, 23 Mar 2016 23:00:00 +0100

Introduction Oral healthcare in nursing homes is less than optimal, with severe consequences for residents' health and quality of life. To provide the best possible oral healthcare to nursing home residents, care providers need strategies that have been proven to be effective. Strategies can either encourage and motivate residents to perform oral healthcare themselves or can prevent or overcome responsive behaviours from residents when care providers assist with oral healthcare. This systematic review aims to identify studies that evaluate the effectiveness of such strategies and to synthesise their evidence. Methods and analysis We will conduct a comprehensive search in the databases MEDLINE, EMBASE, Evidence Based Reviews—Cochrane Central Register of Controlled Trials, CINAHL and ...



Severe tooth loss after root damage caused by predrilled intermaxillary fixation screw: a case report

Wed, 23 Mar 2016 20:13:42 +0100

Abstract Intermaxillary fixation (IMF) with screws is routinely used as a conservative therapy or to obtain normal occlusion during the surgical procedure of open reduction and internal fixation for treating mandibular fractures. The risk of iatrogenic dental damage caused by interdental drilling is widely known. Several side effects are described, including loss of response to pulp sensibility testing, root fracture, and, loss of the tooth. This is a case report about a young man who had undergone temporary IMF treatment with a single proven root damage. The patient did not appear for follow‐up but he presented 5 years afterward with local purulent osteomyelitis concerning the affected and the adjacent teeth. Osteotomy and extraction of two premolars and one molar were necessary for reh...
