Aims
Obesity is a chronic medical condition associated with various oral health problems. The aim of this study was to assess the knowledge, perceptions, and attitudes of dental students towards obesity.Material and methods
Second-, third-, and fourth-year dental students completed a self-administered questionnaire. An ethics committee approved the study. Participants were asked questions focused on three areas: (i) knowledge, (ii) perceptions, and (iii) attitudes about obesity. Data analyses were carried out using SPSS version 20.Results
Among the dental students, 78.9% received 0–1 h of formal education about obesity. The mean score of the total time allocated for obesity-related education was 1.31 ± 0.23 h. Eighty-nine percent of the dental students agreed that obesity is a chronic medical condition, 30% agreed that they would modify their equipment and office furniture to accommodate obese patients, and 46.8% were interested in learning more about obesity in dental school.Conclusion
Obesity-related education should be implemented as a formal component of dental student training. Oral health practitioners should also provide their patients with information about how weight loss is beneficial to both general and oral health. 相似文献2.

Acetylsalicylic acid (ASA) generically known as aspirin is used clinically as an analgesic, antipyretic, anti-inflammatory and as a medication to prevent platelet aggregation. Many studies have investigated bleeding associated with ASA.
Objective
The aim of this study was to determine if ASA was associated with bleeding after dental extraction.Patients and methods
One hundred and eighty-nine subjects were divided into four groups. Group 1A subjects who received ASA, underwent simple extraction. Group 1B subjects who received ASA, underwent surgical extraction. Group 2A subjects who did not receive ASA, underwent simple extraction which served as control group. Group 2B subjects who did not receive ASA, underwent surgical extraction which also served as control group.Results
The results showed that Group 1B was the only group which showed bleeding after 24 h. All groups had similar results after 48 h and 5 days post-operatively.Conclusion
The study concluded that subjects who received 81 mg ASA daily could undergo dental extraction without bleeding risks. 相似文献3.

Background
The aim of this in study was the evaluation of treatment outcomes after using a hybrid hyrax-facemask combination in growing class III patients.Methods
Treatment of 16 children (mean age 9.5 ± 1.3 years) was investigated clinically and by means of pre- and post-treatment cephalograms. Changes in sagittal and vertical, and dental and skeletal values were evaluated and tested for statistically significant differences.Results
All mini-implants remained stable during treatment. Mean treatment duration was 5.8 ± 1.7 months. There was a significant improvement in skeletal sagittal values: SNA, +2.0°; SNB, -1.2°; ANB, +3.2°; WITS appraisal, +4.1 mm and overjet, +2.7 mm. No significant changes were found concerning vertical skeletal relationships and upper incisor inclination. In relation to A point, the upper first molars moved mesially about 0.4 mm (P = 0.134).Conclusions
The hybrid hyrax-facemask combination seems to be effective for orthopaedic treatment in growing class III patients. Unwanted maxillary dental movements can be avoided due to stable skeletal anchorage. 相似文献4.
Background
Tooth extraction is performed for a wide variety of reasons as we know. Several techniques aiming at enhancing the regeneration process in the extraction socket have been adopted such as filling the socket with autogenous bone grafts or bone substitutes. We know platelets play a central role in hemostasis and healing processes but relative contradictory effect of platelet in bone regenerating capacity have been published in different in vitro and in vivo studies.Method
To explore this we used platelet-rich plasma (PRP) (autogenous) alone in empty extraction socket of bilateral impacted mandibular third molars. For that we selected five patients having bilateral impacted teeth. Out of two sockets one was used as intervention by filling with PRP and the other was allowed to heal without PRP. All patients were followed for clinical and radiological evaluation by using digital OPG view after 1 week, 1, 2 and 4 months period.Result and conclusion
PRP enhanced the osteogenic response in initial bone healing at 1 month duration but there was no added benefit in late bone healing at 4 months period compared in both intervention and control groups. However PRP significantly improved the soft tissue healing in PRP treated sites compared to control group. 相似文献5.

Introduction
Post operative care of sutured wound is important after surgery. Sutured wounds within the oral cavity are kept clean through frequent rinses with either normal saline, chlorhexidine mouth rinses, hydrogen peroxide diluted with saline, or fresh tap water.Patients and Methods
The patients were randomised into 3 groups (A, B and C). The container used had 34 chlorhexidine, 34 warm saline and 32 warm water mouth rinses. The latter served as control. All selected patients had scaling and polishing done preoperatively when needed. All participants in each group did not receive antibiotics but received analgesics (paracetamol 1 g 8 h for 5 days,).Results
There were 49 females and 51 males, in the age range between 18 and 50 years. Microorganisms were found to grow on sutures with streptococcus viridians predominating followed by staphylococcus epidermides. The effects of chlorhexidine, warm saline and warm tap water mouth washes were not statistically significant.Conclusion
Chlorhexidine, warm salt water and warm tap water averagely produced the same number of colony forming units of bacteria, which shows that the three different mouth washes are equally effective as post-operative mouth rinses after oral surgery. 相似文献6.

To evaluate the efficacy of autologous platelet rich fibrin in soft tissue healing and bone regeneration in mandibular third molar extraction sockets.
Method
The study was conducted in 20 patients visiting in outpatient department of Oral and Maxillofacial Surgery, requiring extraction of bilateral mandibular third molar, following extraction platelet rich fibrin (PRF) was placed in one extraction sockets, the other socket was studied as the control sites with no PRF. The patient were assessed for post operative pain, soft tissue healing and trabecular pattern in healing bone. Radiological assessment of the extraction site was done for period of 3 months to evaluate the change in bone density.Results
Pain was less in study side compare to control site soft tissue was healing was better in study site. Evaluation of trabecular bone formation started earlier in PRF site compare to control site. The evaluation of bone density by radiological assessment showed the grey level value calculated after 3 months at the PRF site well comparatively higher than the average baseline value of the bone density at the extraction site in control site.Conclusion
The study showed that autologous PRF is biocompatible and has significantly improved soft tissue healing. Bone regeneration and increase in bone density in extraction sockets. However, a more elaborate study with a large number of clinical cases is essential to be more conclusive regarding its efficacy. 相似文献7.

Background
Pain is a major public health problem and is the most commonly reported symptom of oral and dental disease that has a significant impact on both individual and community. The present study was prevalence of various orofacial pain symptoms and their overall impact on the quality of life in a tertiary care hospital.Materials and Methods
This study was carried out in the outpatient department of the Government Dental College and Research Institute, Bangalore. The severity of the chronic orofacial pain symptoms was assessed using the Chronic Pain Grade Questionnaire by Von Korff.Results
The results showed that toothache (57.6 %) was the most commonly reported symptom and burning mouth sensation (6.4 %) was the least commonly reported. Majority of the patients had grade 3 level of pain-related disability (34.8 %) followed by grade 2 (26.8 %), grade 1 (22.4 %) and grade 4 levels (16 %). The mean pain intensity was reported to be more among females and maximum among patients with facial pain.Conclusion
The present study demonstrated that orofacial pain symptoms have a significant impact on the patients suffering from it. Therefore, proper measures should be taken for the management of the patients with these symptoms and associated conditions. 相似文献8.

Aim
To determine the fits of preformed nickel titanium (NiTi) archwires on dental arches with normal occlusion.Methods
Forty sets of upper and lower plaster models were obtained from men and women with Class I occlusions. Preformed 0.016″ × 0.022″ NiTi archwires from Rocky Mountain Orthodontics (RMO), 3 M Unitek, Ormco, and Dentaurum were evaluated in terms of their fits on dental arches from male, female, and combined cases. Data were analyzed by using fourth- and sixth-order polynomial equations, analysis of variance (ANOVA), and the Duncan post hoc test.Results
In the upper arches, the best fit and least error were obtained with RMO Ovoid and Ormco Orthos Large archwires for male cases, but with 3 M Orthoform LA archwires for female and combined cases. In the lower arches, the best fit and least error were obtained with Ormco Orthos Large for male cases, with 3 M Orthoform LA and RMO Normal for female cases, and with 3 M Orthoform LA, RMO Normal, Ormco Orthos Large, and Ormco Orthos Small for combined cases. When both dental arches were matched, Ormco Orthos Large was the best wire for male cases. 3 M Orthoform LA was the best wire for female and combined cases.Conclusions
Using an archwire form with the best fit to the dental arch should produce minimal changes in the dental arch form when NiTi wires are used and require less customization when stainless-steel wires are used. 相似文献10.
Aim
Smoking is the one of the most preventable causes of death worldwide. Dental professionals may play an important role in anti-smoking campaigns. The aim of this study was to evaluate current knowledge of and attitudes toward smoking and its cessation among dental professionals.Materials and methods
This questionnaire-based study was carried out among general dental practitioners (GDPs) and dental students in Saudi Arabia. The questionnaire was used to collect data on sociodemographic characteristics, knowledge, and attitudes toward tobacco use and cessation. Data were analyzed using SPSS software (version 18.0; IBM) and the Mann–Whitney U-test, with a significance level of p < 0.001.Results
A total of 342 participants (130 GDPs, 212 dental students) with the mean age of 24 (standard deviation, 5) years participated in the study. One-third (33.8%, n = 44) of GDPs and 30.2% (n = 64) of dental students were smokers; small percentages (GDPs, 9.1% [n = 4]; dental students, 7.8% [n = 5]) were heavy smokers. The majority of participants rated both smoking cessation and prevention together as a very important preventive measure. Families were rated as the most important factor responsible for smoking cessation, whereas general practitioners were rated as the most important factor for providing assistance with cessation.Conclusion
More meaningful participation of dental professionals in tobacco cessation is needed, with implications for related curriculum changes. 相似文献11.

Aim
This study aimed to carry out a case-control research study to assess occurrence of clicking of the temporomandibular joint (TMJ) in order to establish the relationship between TMJ clicking and the genotype of “ANKH inorganic pyrophosphate transport regulator” (ANKH) polymorphisms.Materials and Method
A sample of 41 first-year dental residents was selected. Each was examined using standard clinical procedures and genotyping techniques.Results
The participation rate was 91.8 %. The prevalence of TMJ clicking was 51.2 % (95 % CI: 35.7–66.7 %). Occurrence of TMJ clicking was not related to age, gender and genotypes of ANKH-OR as well as ANKH-TR polymorphisms (p ≥ 0.165).Conclusion
A similar distribution of ANKH genotypes in TMJ clicking and asymptomatic individuals has been demonstrated by this study. A high percentage of TMJ clicking has been confirmed. Future investigations are indicated. 相似文献12.

Objective
This paper focused on optimal stress distribution in the mandibular bone surrounding a dental implant and is devoted to the development of a modified Osteoplant® implant type in order to minimize stress concentration in the bone-implant interface.Material and Methods
This study investigated 0.4 mm thick layers of two elastomeric stress barriers incorporated into the dental implant using 3-D finite element analysis.Results
Overall, this proposed implant provoked lower load transfer in bone-implant interface due to the effect of the elastomers as stress absorbers. The stress level in the bone was reduced between 28% and 42% for three load cases: 75 N, 60 N and 27 N in corono-apical, linguo-buccal and disto-mesial direction, respectively.Conclusion
The proposed model provided an acceptable solution for load transfer reduction to the mandible. This investigation also permitted to choose how to incorporate two elastomers into the Osteoplant® implant system. 相似文献13.

Introduction
Ropivacaine belongs to pipecoloxylidide group of local anesthetics. There are reports supporting the use of ropivacaine as a long acting local anesthetic in oral and maxillofacial surgical procedures, with variable data on the concentration that is clinically suitable.Materials and Methods
A prospective randomized double-blind study protocol was undertaken to assess the efficacy of 0.5 and 0.75 % ropivacaine for inferior alveolar nerve block in surgical extraction of impacted mandibular third molars. A total of 60 procedures were performed, of which thirty patients received 0.5 % and thirty received 0.75 % concentration of the study drug.Results
All the patients in both the study groups reported subjective numbness of lip and tongue. The time of onset was longer for 0.5 % ropivacaine when compared to 0.75 % solution. 90 % of the study patients in 0.5 % ropivacaine group reported pain corresponding to VAS ≥3 during bone guttering and 93.3 % patients reported pain corresponding to VAS >4 during tooth elevation. None of the patients in 0.75 % ropivacaine group reported VAS >3 at any stage of the surgical procedure. The duration of soft tissue anesthesia recorded with 0.75 % ropivacaine was average 287.57 ± 42.0 min.Conclusion
0.75 % ropivacaine was found suitable for inferior alveolar nerve blocks in surgical extraction of impacted mandibular third molars. 相似文献14.

Background
This study aims to compare the ‘Nuvola®’ system with ‘Fantasmino®’ system, examine their material properties, and define the indications for use of the aligners.Methods
Two groups of patients were selected and were respectively treated with Nuvola® aligner and Fantasmino® system.Results
The goal of treatment has been achieved with the two systems.Conclusions
The two types of aligners have shown differences during the treatment. Fantasmino® system has elastic properties of high performance, but its size does not encourage compliance throughout the day. Nuvola® system determines good tooth movement and its size facilitates the patient’s collaboration. In both aligner systems, difficulties were found in the correction of torque information and rotations. 相似文献15.

Objective:
The purpose of this study was to compare the accuracy of two working cast fabrication techniques using strain- gauge analysis.Methods:
Two working cast fabrication methods were evaluated. Based on a master model, 20 working casts were fabricated by means of an indirect impression technique using polyether after splinting the square transfer copings with acrylic resin. Specimens were assigned to 2 groups (n=10): Group A (GA): type IV dental stone was poured around the abutment analogs in the conventional way; Group B (GB), the dental stone was poured in two stages. Spacers were used over the abutment analogs (rubber tubes) and type IV dental stone was poured around the abutment analogs in the conventional way. After the stone had hardened completely, the spacers were removed and more stone was inserted in the spaces created. Six strain-gauges (Excel Ltd.), positioned in a cast bar, which was dimensionally accurate (perfect fit) to the master model, recorded the microstrains generated by each specimen. Data were analyzed statistically by the variance analysis (ANOVA) and Tukey''s test (α= 5%).Results:
The microstrain values (με) were (mean±SD): GA: 263.7±109.07με, and GB: 193.73±78.83με.Conclusion:
There was no statistical difference between the two methods studied. 相似文献16.

PURPOSE
The purpose of this preliminary study was to investigate the effects of adding 4,4''-bis(N,N-diethylamino) benzophenone (DEABP) as a co-initiator to a binary photoinitiating system (camphorquinone-amine) to analyze on the degree of conversion (DC) of a light-cured resin for dental 3D printing.MATERIALS AND METHODS
Cylindrical specimens (N=60, n=30 per group, ø5 mm × 1 mm) were fabricated using bisphenol A glycerolate dimethacrylate (BisGMA) both with and without DEABP. The freshly mixed resins were exposed to light in a custom-made closed chamber with nine light-emitting diode lamps (wavelength: 405 nm; power: 840 mW/cm2) for polymerization at each incidence of light-irradiation at 10, 30, 60, 180, and 300 seconds, while five specimens at a time were evaluated at each given irradiation point. Fourier-transform infrared (FTIR) spectroscopy was used to measure the DC values of the resins. Two-way analysis of variance and the Duncan post hoc test were used to analyze statistically significant differences between the groups and given times (α=.05).RESULTS
In the DEABP-containing resin, the DC values were significantly higher at all points in time (P<.001), and also the initial polymerization velocity was faster than in the DEABP-free resin.CONCLUSION
The addition of DEABP significantly enhanced the DC values and, thus, could potentially become an efficient photoinitiator when combined with a camphorquinone-amine system and may be utilized as a more advanced photopolymerization system for dental 3D printing. 相似文献17.

Background
The purpose of this study was to compare the occlusal stability of class II subdivision malocclusion treatment with 3 and 4 first premolar extractions. A sample of 156 dental casts from 52 patients with class II subdivision malocclusion was divided into two groups according to the extraction protocol. Group 1 comprised 24 patients treated with 3 premolar extractions and group 2 included 28 patients treated with 4 premolar extractions.Methods
Peer assessment rating (PAR) indexes were measured on the dental casts obtained before (T1) and after treatment (T2) and at a mean of 6.9 years after the end of treatment (T3). The groups were matching regarding sex distribution, pretreatment, posttreatment and long-term posttreatment ages, and treatment and long-term posttreatment times. They were also comparable concerning the initial malocclusion severity and the occlusal results at the end of treatment. Stability evaluation was calculated by subtracting the posttreatment from the long-term posttreatment index values (T3 − T2). T tests were used to compare the amount and percentage of long-term posttreatment changes.Results
There were no intergroup differences regarding the amount and percentage of long-term posttreatment changes.Conclusion
Treatment of class II subdivision malocclusion with 3 and 4 premolar extractions have a similar long-term posttreatment occlusal stability. 相似文献18.
Background
Alveolar bone grafting in unilateral cleft lip/palate (CLP) patients can improve nasal symmetry and facial esthetic. In some cases lateral piriform hypoplasia cannot be compensated by soft tissue thickness of the face, necessitating onlay bone grafting. This study was designed to estimate the proportion of patients among unilateral CLP patients requiring this procedure.Materials and Methods
In a retrospective study, unilateral CLP patients with severe paranasal deficiency, who were managed by paranasal augmentation with cortico-cancellous bone graft during the alveolar cleft bone grafting, were included.Results
From 85 unilateral CLP patients treated from 2005 to 2011 in the Oral and Maxillofacial Surgery Department, Mashhad University of Medical Sciences, fourteen patients were treated with lateral piriform augmentation technique. Mean age of the patients at the time of operation was 16 ± 4.8 years. Follow-up period was 2–6 years.Conclusion
Concomitant alveolar bone grafting and lateral piriform augmentation is needed at least in 16.5 % of unilateral CLP patients. 相似文献19.

Objectives
This study was conducted to determine factors affecting utilization of dental health services among intermediate female school students in Riyadh. In addition to assessing their satisfaction with the dental care received during the last dental visit.Subjects and methods
Self-administered questionnaires were distributed among students attending eight public and four private schools. These schools were selected randomly to represent the four different administrative zones in Riyadh.Results
Of 600 questionnaires distributed, 531 were complete and suitable for analysis. Nearly three quarters of the students visited the dentist more than once during the last 2 years. A bout 75% had their treatment in private dental clinics and 63% made their visits for routine treatment. The quality of dental care was found to be the most encouraging factor for utilization of dental services, whereas, far geographic location of the dental clinics was the most discouraging factor. For those who received treatment in the government clinics, the most discouraging factor was post operative complications (P < 0.0001), while the most encouraging factor was the availability of friendly staff (P < 0.0001). The high cost of dental care was the most discouraging factor for utilizing the dental services for those who visited private clinics (P < 0.0001), while the high quality of dental care was the most encouraging factor (P < 0.009). Students who made their visits because of pain highly considered modern clinics and those recommended by friends as highly encouraging factors (P < 0.002), while they considered the high cost of dental care as discouraging factor for using dental services (P < 0.038). Students who visited the dentist for routine treatment gave the quality of dental care as encouraging for the use of dental clinics (P < 0.0001). Satisfaction with dental care was found to be significantly associated with high quality of dental care, convenient appointment, friendly staff, modern dental clinics and clinics recommended by friends.Conclusion
Quality of dental care, reasonable fees for dental services and close location of dental clinics to students’ homes are encouraging factors for utilization of dental services. 相似文献20.
