Aim: To analyze the level of knowledge, attitude, and practice among dental practitioners working in dental clinics towards standard infection control protocol.Materials and methods: This pilot study was a cross-sectional survey conducted on 42 dental practitioners working in Jaipur, Rajasthan. A questionnaire with three parts (knowledge, attitude, and practice) was filled by direct interview or by email to the participants. The answers was compiled and subjected to analysis.Results: The survey was completed by 42 (70%) of 60 potential respondents. The mean ± SD scores of knowledge, attitude, and practice towards standard isolation precautions were 8.24 ± 1.39, 39.45 ± 3.76, and 4.19 ± 2.46 from the maximum scores of 10, 50, and 10, respectively.Conclusion: Isolation protocol is loosely followed among dental professionals. Having knowledge and positive attitude towards infection control guidelines did not guarantee that the same were followed.

Gingival recession can cause aesthetic problems, discomfort for cervical dentin hypersensitivity and can be treated by connective tissue grafts. This case report used subepithelial connective tissue graft to treatment class I Miller recession in premolar lower with abrasion. The premolar were treated by scaling and root planing chemical modification with 24% ethylenediaminetetraacetic acid (EDTA), bur shaped reconteur of abrasion lesion and subepithelial connective tissue graft combined with coronal flap. The results provide excellent root coverage, improve the root hypersensitivity and abrasion lesion. Although the longevity of this successful treatment depends on the diagnosis and removal of the causative agent, as well as the patient's cooperation in maintained of oral hygiene.

In recent years, decrease in dentin bond strength of one-step self-etch adhesives after long-term water storage has been reported; however, the flat dentin surface of the extracted tooth has been used to carry out the bond strength tests in the majority of the previous studies. Objectives: The purpose of this study was to compare the micro-tensile-bond-strength (μTBS) of three one-step self-etch adhesives and a two-step self-etch adhesive on the cavity floor dentin after 2.5 years storage in distilled water. Materials and Methods: Adhesives were used in this study: three one-step self-etch adhesives (Primefil, GBOND PLUS and Beauti Bond), and one two-step self-etch adhesive (Clearfil SE Bond), which was used as the control. Bowl-shaped cavities of extracted human incisors were treated with each adhesive and filled with each flowable resin composite from the same manufacturer. The specimens were stored in distilled water at room temperature for two and a half years. The beam samples were made and subjected to μTBS test using the tabletopmaterial- tester. The data were statistically analyzed using one-way ANOVA. Results: The μTBS value of G-BOND PLUS was higher than that of other adhesives; however, the results of ANOVA showed no significant differences in μTBS values among all adhesives. Conclusion: There was no significant difference between one-step and two-step on the bond strength of selfetch adhesives to the cavity dentin floor after a storage period of 2.5 year.
近年来有一步自蚀刻胶粘剂在长期蓄水后牙本质粘结强度下降的报道;然而,在以往的研究中,大多数都是利用拔牙后牙本质的平面来进行粘结强度测试。目的:比较三种一步自蚀胶与两步自蚀胶在蒸馏水中保存2.5年后对牙本质的微拉伸粘结强度(μTBS)。材料与方法:本研究使用胶粘剂:3种一步自蚀胶粘剂(Primefil、GBOND PLUS和Beauti Bond)和1种两步自蚀胶粘剂(Clearfil SE Bond)作为对照。提取的人门牙的碗状腔分别用同一厂家的粘合剂和可流动树脂复合材料进行处理。标本在室温蒸馏水中保存两年半。制作梁样,用台式材料测试仪进行μTBS测试。数据采用单因素方差分析进行统计学分析。结果:G-BOND PLUS的μTBS值高于其他胶粘剂;方差分析结果显示,各胶粘剂的μTBS值差异无统计学意义。结论:一步法与二步法自粘剂在保存2.5年后与牙本质底的结合强度无显著性差异。

Introduction: Cleidocranial dysplasia CCD is a rare genetic disorder connected with mutation in the gene RUNX2. The characteristic feature of this syndrome is a triad of symptoms: hypoplasia or aplasia of clavicles, cranial defects, persistent decidous teeth and multiple supernumerary teeth with consecutive failure in succedaneous teeth eruption. Objective: The aim of the study is to present a CCD patient, in which during orthodontic treatment there was performed a comprehensive hearing test. Case report: The paper presents a 15-year-old patient in whom intraorally there were stated only 4 first permanent molars and 1 lower central incisor while all the remaining teeth were decidous. The CBCT showed 11 impacted supernumerary teeth. Treatment started by surgical exposure and orthodontic traction of the upper incisors into the arch. The introduced fixed appliance seems to be a good solution to pull down impacted anterior teeth. An audiological examination of the patient with CCD revealed normal hearing on the border of norm, however tympanometry may suggest a defect of the auditory ossicles. Conclusion: Active long-term treatment that requires cooperation of many specialists is the correct procedure in CCD cases.
闭锁颅发育不良CCD是一种罕见的遗传性疾病,与RUNX2基因突变有关。该综合征的特征是三联征:锁骨发育不全或发育不全,颅骨缺损,乳牙持续存在,多颗多牙连续出牙失败。目的:本研究的目的是介绍一个CCD患者,在正畸治疗期间进行了全面的听力测试。病例报告:本文报告一名15岁的患者,其口腔内只有4颗第一恒磨牙和1颗下中切牙,其余牙齿均为乳牙。CBCT显示11颗埋伏多生牙。治疗开始于手术暴露和正畸牵引上门牙到弓。所介绍的固定矫治器是一种较好的前牙拔除方法。CCD患者的听力学检查显示听力正常,但鼓室测量可能提示听骨缺损。结论:积极长期治疗是治疗CCD的正确方法。

Introduction: Complex root canal anatomies challenge the limits of our skills, techniques, and abilities to clean the root canal system and achieve a successful endodontic outcome. Background: The following case report depicts a first mandibular molar indicated for root canal treatment after diagnosis of pulpal necrosis and asymptomatic apical periodontitis due to caries. Pre-operative radiographic analysis revealed two distinct periapical lesions and a Periapical Index (PAI) Score of 3. Methods: The tooth was accessed for root canal treatment and instrumented to a final apical size of #20. Additional cleaning and disinfection were performed utilizing the GentleWave® System. After the GentleWave® Procedure, the tooth was obturated with gutta-percha and an epoxy resin based sealer by warm vertical condensation and thermoplasticized gutta-percha backfill. Post-operative radiographs revealed a middle mesial canal not previously visualized during instrumentation or prior to performing the GentleWave Procedure. The newly located, uninstrumented, middle mesial canal was filled with sealer. Results: Recall was performed over a 9-month period. Both clinical and radiographic assessments showed complete healing, no clinical signs or symptoms, and a PAI score of 1 at the 9-month recall. This case illustrates healing after root canal treatment utilizing minimal instrumentation and the GentleWave Procedure, suggesting that GentleWave Procedure can clean and disinfect complex root canal anatomy.
简介:复杂的根管解剖挑战了我们清洁根管系统和实现成功根管治疗结果的技能、技术和能力的极限。背景:下面的病例报告描述了一个下颌第一磨牙在诊断为牙髓坏死和无症状的根尖牙周炎后进行根管治疗。术前放射学分析显示两个明显的根尖周围病变和根尖周围指数(PAI)评分为3。方法:拔牙行根管治疗,最终根尖尺寸为#20。使用绅士波®系统进行额外的清洁和消毒。在GentleWave®手术后,用杜仲胶和环氧树脂为基础的密封剂通过热垂直冷凝和热塑性杜仲胶回填进行牙齿封闭。术后x线片显示中内侧椎管,在器械检查期间或行轻柔波手术前未见。新定位的,没有器械的,中中肛管用密封剂填充。结果:在9个月的时间内进行召回。临床和影像学评估均显示完全愈合,无临床体征或症状,9个月时PAI评分为1。本病例说明了使用最小器械和绅士波浪手术进行根管治疗后的愈合,表明绅士波浪手术可以清洁和消毒复杂的根管解剖结构。

Objective: This study was performed to evaluate the results of carbon dioxide laser in the treatment of trigeminal neuralgia (TN). Methods: Thirty six patients (11 men, 25 women) with refractory TN underwent peripheral nerve ablation with CO2 laser using low power defocused mode. Pain intensity was determined by numerical rating scales at preoperation, 1 week, 1 month, 3 months, 6 months, and 12 months post-operation. One way ANOVA was used to determine statistical significance. Results: There were significant differences in pain between pre-operation and 1 week, 1 month, 3 months, 6 months, and 12 months post-operation (pain score=9.38 ± 0.91, 3.15 ± 3.24, 1.00 ± 1.41, 0.63 ± 1.18, 0.75 ± 1.16 and 1.63 ± 1.99 respectively; p<0.05). Thirty four patients had some degree of prolonged paresthesia of the effected nerves, while two patients had no sensory alteration but the pain was relieved. Conclusions: Neural ablation with CO2 laser can be an alternative treatment for patients with TN who do not respond to the medical treatment or cannot tolerate the side effects of medication or do not want to have intracranial surgery. The only complication was prolonged paresthesia of the effected nerve. However, further study with a larger group of patients and longer observation period are recommended to evaluate the outcome of this treatment.
目的:评价二氧化碳激光治疗三叉神经痛(TN)的效果。方法:36例难治性TN患者(男11例,女25例)采用低功率离焦模式CO2激光消融周围神经。分别于术前、术后1周、1个月、3个月、6个月、12个月采用数值评定量表测定疼痛强度。采用单因素方差分析确定统计显著性。结果:术前与术后1周、1个月、3个月、6个月、12个月疼痛评分差异有统计学意义(疼痛评分分别为9.38±0.91、3.15±3.24、1.00±1.41、0.63±1.18、0.75±1.16、1.63±1.99;p < 0.05)。34例受累神经有不同程度的长时间感觉异常,2例无感觉改变,但疼痛得到缓解。结论:CO2激光神经消融对于治疗无效、不能耐受药物副作用或不愿颅内手术的TN患者可作为一种替代治疗方法。唯一的并发症是受累神经长时间感觉异常。然而,建议进一步研究更大的患者群体和更长的观察期来评估这种治疗的效果。

Pain intensity was determined by numerical rating scales at preoperation, 1 week, 1 month, 3 months, 6 months, and 12 months post-operation. One way ANOVA was used to determine statistical significance. Results: There were significant differences in pain between pre-operation and 1 week, 1 month, 3 months, 6 months, and 12 months post-operation (pain score=9.38 ± 0.91, 3.15 ± 3.24, 1.00 ± 1.41, 0.63 ± 1.18, 0.75 ± 1.16 and 1.63 ± 1.99 respectively; p<0.05). Thirty four patients had some degree of prolonged paresthesia of the effected nerves, while two patients had no sensory alteration but the pain was relieved. Conclusions: Neural ablation with CO2 laser can be an alternative treatment for patients with TN who do not respond to the medical treatment or cannot tolerate the side effects of medication or do not want to have intracranial surgery. The only complication was prolonged paresthesia of the effected nerve. However, further study with a larger group of patients and longer observation period are recommended to evaluate the outcome of this treatment.","PeriodicalId":110010,"journal":{"name":"JBR Journal of Interdisciplinary Medicine and Dental Science","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132591742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bone resorption often prevents elderly patients from wearing complete mandibular over dentures. This has a negative impact on the quality of life of patients, since it affects their speech, chewing ability and social relationships. Implant-supported over dentures have been proven to be superior to conventional dentures, both in terms of retention and stability. We report the case of an 82 year-old woman with a severely resorbed mandible that was rehabilitated with a 2-implant supported mandibular over denture. According to the reviewed literature, 2-implant over dentures is the preferred treatment for elderly patients with bone resorption due to its simplicity and reliability in the long-term.
骨吸收常妨碍老年患者戴全下颌假牙。这对患者的生活质量有负面影响,因为这会影响他们的言语、咀嚼能力和社会关系。种植支撑假牙已被证明优于传统的假牙,无论是在固位和稳定性方面。我们报告的情况下,一个82岁的妇女严重吸收下颌骨,是恢复与2种植体支持下颌骨超过义齿。根据文献综述,2种植体复盖义齿因其简单、长期可靠而成为老年骨吸收患者的首选治疗方法。

Aim: The present study was conducted to access the prevalence of deleterious oral habits among school going children as these practices have a great impact on the dental hard and soft tissues. Methodology: This study was conducted among children aged between 7 to 13 years. The sample was selected from urban and rural schools. A closed-ended questionnaire was used in the survey for collecting the information like age, gender, area of residence and presence of deleterious oral habits. These questions were asked to parents for the habits like bruxism, tongue thrusting, digital sucking, mouth breathing, nail biting and lip biting. Chi-square test compared the frequency of oral habits in relation to age, sex and area. Statistical tests were used at a significance level of p<0.05. Results: It was noticed that bruxism (14.4%) was most common habit followed by mouth breathing (12.6%), digital sucking (9.2%), nail biting (8.3%), lip biting (8.1%) and tongue thrusting (7.2%). Bruxism (4.7%) and tongue thrusting (3.4%) had the highest occurrence in (9 to 11 years) group. Digital sucking (3.6%) and mouth breathing (6.3%) was mostly observed among younger age group (7 to 9 years). However nail biting (4.3%) and lip biting (4.7%) was commonly noticed in older sample. Conclusion: The study observed that bruxism was most frequent habit among children. There was also a variation in the occurrence of oral habits in relation to age.
