Loss of any anatomical structure leads to functional insufficiency and psychological trauma. Malignant neoplasms of mandible are often surgically treated by hemimandibulectomy which greatly affects the function postoperatively. The amount of dysfunction depends upon the size of resected segment, effect on tongue, number of remaining teeth, and the extent of loss of sensory and motor innervations. This clinical report describes the prosthodontic management of a squamous cell carcinoma patient treated with hemimandibulectomy and rehabilitated using balancing ramp-guided flexible prosthesis to accommodate mandibular deviation and limited mouth opening.

Background: There is a high prevalence of work-related musculoskeletal disorders in dentists. The most commonly affected areas are the neck, low back, wrist, and hand. The symptoms of the musculoskeletal disorder occur during the educational and training course in dental students. Aim: The aim of this study was to assess neck pain and the scapular stability in graduate dental students. Study Design: This was an observational, cross-sectional study. Study Setting: This study was conducted at a dental college attached to a tertiary care hospital. Methods: The site of pain over the neck region (in subjects with pain) was assessed using body diagrams. Assessment of intensity of pain (if present) was done using Numerical Rating Scale, scapular posture using the pectoralis minor (PM) length test and resting scapular upward rotation using Baseline Bubble Inclinometer, dynamic scapular positioning using Lateral Scapular Slide Test, and muscle strength of scapular stabilizers using Lafayette Manual Muscle Tester. The outcome measures were compared between 1st-year undergraduate dental students (Group A) and dental interns (Group B). Results: Sixty-three female dental students (Group A, n = 32; Group B, n = 31) were included. There was a significant difference in the PM length test of left side (P = 0.02) and intensity of pain (right side P = 0.008, left side P = 0.003) in Groups A and B. The site of pain was over the lateral aspect of the neck and the character of pain was aching. We found no significant difference in other outcome measures. Conclusion: Dental students suffer from neck pain. Static scapular posture was affected, whereas the dynamic scapular stability was not affected.

Background: Among the postoperative complications following periodontal surgery, the risk of infection stands out the most since infection of the surgical site can lead to poor surgical outcomes in terms of wound healing. Aim: This study aims to evaluate antibiotic-prescribing practices for various periodontal surgeries in vicinity of Nagpur city. Materials and Methods: An anonymous survey was distributed to periodontists through Google forms. The survey questioned prescribing practices for various periodontal surgeries, the demographic data and place of practice of the clinician, rationale for prescribing or not prescribing antibiotics, and acceptability of guidelines. The survey consisted of 12 questions, 7 of which were questioned to the practitioners “In an otherwise healthy patient, would you prescribe antibiotics for a X procedure” where X included various periodontal surgeries. Response choices were limited to “In most cases yes, in most cases no and I do not perform this procedure.” Results were analyzed using statistical software. Results: A total of 50 periodontists responded out of 98 who were contacted to participate in the survey with a response rate of 51%. Nearly 58% of practitioners had a predominant work setting of a dental college and 42% have a predominant work setting of private practice. Practitioners were significantly more likely to prescribe antibiotics all the periodontal surgical procedures. The most common rationale for prescribing antibiotics was to decrease the chances of developing an infection, whereas the most common rationale for not prescribing antibiotics was a healthy patient and based on current and previous literature. Nearly 66% of practitioners reported that they would follow the guidelines for antibiotic prescription if they were developed by American Academy of Periodontology (AAP). Bivariate analysis revealed that there is no significant role of other characteristics on the response of an individual. Even multivariate analysis does not reveal significance of baseline characteristics although it revealed that respondents working in a dental college are 2.15 times more likely to follow AAP guidelines as compared to private practitioners. Females are 1.64 times more likely to follow AAP guidelines as compared to males and respondents practicing inside Nagpur are 1.35 times more likely to follow AAP guidelines as compared to those practicing outside city. Conclusion: Practitioners are more likely to prescribe antibiotics in the majority of the periodontal surgical procedures despite the standard indications for prescription. This misuse can lead to numerous complications in treatment and development of antibiotic resistance. Based on these results, specific guidelines for the use of antibiotics suggesting a particular antibiotic to be used in a particular periodontal surgery and its duration is the need of the hour to prevent the overuse of antibiotics.

Introduction: It is crucial to take care of stability between various implant parts for the general success rate of the reconstruction. Component fit, saliva contamination, machining accuracy, and screw preload influence the steadiness of implant–abutment connection. Loosening of abutment screws has been a well-known technical problem. Aim: The aim of this study was to gauge repeated tightening and loosening torque on two commercially available implant/abutment connection designs. Study Design: This was an in vitro study. Methodology: A total of 32 implant analogs samples using a metal die with, metal ring of 20mm x 20mm x 20mm in size and a hole in the center were prepared. For both the groups, the implant analog was axially threaded within bases. They were clasped at an edge parallel to the standard minimal bone position. A 35 N/cm torque was enforced, each implant and abutment connection in both the groups using toque ratchet. After 20 min, screws were loosened and detorque measurement was recorded up to ten times. Scanning electron microscope micrographs of selected screws also are presented. SPSS (21.0 version) was used for analyzing data. Results: The mean residual torque for Group 1 was − 51.45 and Group 2 was − 43.29. The RTq (%) was found to be significantly less (0.028*) among Group 2: conical connection as compared to Group 1: butt joint connection. Conclusion: The loosening torque was significantly less in conical connection as compared to butt joint connection.
引言：对于重建的总体成功率来说，注意不同植入部位之间的稳定性至关重要。部件配合、唾液污染、加工精度和螺钉预紧力影响种植体-基牙连接的稳定性。桥台螺钉松动一直是一个众所周知的技术问题。目的：本研究的目的是测量两种市售植入物/基牙连接设计的重复拧紧和松动扭矩。研究设计：这是一项体外研究。方法：使用金属模具制备32个植入物类似物样品，金属环尺寸为20mm x 20mm x 20mm，中心有一个孔。对于两组，植入物类似物在基座内轴向螺纹连接。它们被卡在与标准最小骨骼位置平行的边缘。施加35N/cm的扭矩，两组中的每个植入物和基牙连接都使用扭矩棘轮。20分钟后，松开螺钉，并记录多达10次排毒测量。还提供了所选螺钉的扫描电子显微镜显微照片。数据分析采用SPSS（21.0版本）。结果：第1组和第2组的平均残余扭矩分别为−51.45和−43.29。与第1组：对接接头相比，第2组：锥形接头的RTq（%）显著降低（0.028*）。结论：锥形连接的松动力矩明显小于对接连接。

Background: Odontogenic lesions can bring about diagnostic challenges due to overlapping histology among pathologists. Thus, there are few tumor markers that provide accurate diagnosis. Syndecan-1 (CD-138) and podoplanin (PDPN) are proteoglycans that have been described as substantial diagnostic and prognostic markers in various odontogenic lesions. Aim: This study aims to evaluate and compare the immunohistochemical expression of syndecan-1 (CD-138) and podoplanin in keratocystic odontogenic tumor, orthokeratinized odontogenic cyst (OOC), and dentigerous cyst (DC). Materials and Methods: The formalin-fixed paraffin-embedded tissue blocks of KCOT, OOC, and DCs were retrieved form the archives of department. Three sections each of 3 μm thickness were made using a rotary microtome and they were stained with syndecan-1 (CD-138) and podoplanin (PDPN) using immunohistochemical methods and standard hematoxylin and eosin stain. Results: Immunohistochemical expression of syndecan-1in KCOT was found to be weakly to moderately positive in 6 cases with 2 cases exhibiting positive expression. In OOC, 3 cases displayed negative expression-1 whereas 7 cases were weakly to moderately positive. Immunohistochemical expression of podoplanin in KCOT was observed to be weakly to moderately positive in 4 cases with 5 cases exhibiting strongly positive expression. In OOC, 3 cases displayed negative immunohistochemical expression for podoplanin and 4 cases were strongly positive. Immunoreactivity for podoplanin in DC was negative in 3 cases whereas 5 cases were weakly to moderately positive. Conclusion: The absence of significant correlation between expression of syndecan-1 and podoplanin reinforces the exact role of these proteins in the differentiation of odontogenic lesions which need to be elucidated further.

Context: Melanin pigmentation of the gingiva is a physiological process that occurs in all ethnicities. Many treatment modalities are available to treat gingival hyperpigmentation. These are based on the principle of complete removal of the epithelial layer along with a part of subepithelial connective tissue which is then permitted to heal by secondary intention. Aim: This study aims to compare the treatment outcome of laser and its effectiveness in the management of gingival hyperpigmentation over scalpel. Design: A split-mouth study. Methods: Twenty young patients, between the ages of 18–35 with no systemic comorbidities with concerns regarding of dark-colored gums were selected for the study. A split-mouth study involving treatment of melanin pigmentation using scalpel abrasion on one side (left side upper and lower jaws) and Diode laser (980 nm) on other side (right side upper and lower jaws) was carried out. Observations regarding time taken, amount of bleeding during procedure, postoperative pain, healing of wound, and recurrence were made. Statistical Analysis: Data were analyzed using SPSS version 21.0 for Microsoft Windows. Results: Pain and healing were comparable in both the groups, though intraoperative time consumed and bleeding was significantly lower for laser group. Recurrence also was significantly lower on the laser group. Conclusion: Diode lasers can give better results in the management of gingival pigmentation compared to conventional scalpel abrasion technique.

Background: Being healthcare professionals, the dentists should be aware of the basic and practical aspects of basic life support (BLS) and cardiopulmonary resuscitation (CPR). This study helps assess the knowledge and awareness of dental professionals toward it. Aim: The aim of the study is to assess the level of knowledge, awareness, and attitude toward “BLS” among dental students, interns, and dental practitioners. Materials and Methods: This survey-based study enrolled 70 students from 3rd-year BDS, 70 students from final-year BDS, 80 interns, and 45 dental academicians/practitioners of the dental college. A semi-structured, validated, peer-reviewed questionnaire was used with three sections – demographic data, qualification, and experience; knowledge of participants regarding BLS (26 multiple-choice questions); and awareness and attitude toward BLS (7 close-ended questions). Results: Surprisingly, none of the 265 participants had complete knowledge of BLS and CPR. They lacked in basic knowledge of this important lifesaving protocol. The students and interns also were unaware of basic and applied knowledge of BLS, which shows the necessity of its inclusion in BDS curriculum. Conclusion: The understanding of lack of knowledge and awareness about BLS and CPR is alarming. Its inclusion in curriculum, training, and periodic re-training of dental undergraduates, interns, postgraduates, academicians, and practitioners is necessary.

This study helps assess the knowledge and awareness of dental professionals toward it. Aim: The aim of the study is to assess the level of knowledge, awareness, and attitude toward “BLS” among dental students, interns, and dental practitioners. Materials and Methods: This survey-based study enrolled 70 students from 3rd-year BDS, 70 students from final-year BDS, 80 interns, and 45 dental academicians/practitioners of the dental college. A semi-structured, validated, peer-reviewed questionnaire was used with three sections – demographic data, qualification, and experience; knowledge of participants regarding BLS (26 multiple-choice questions); and awareness and attitude toward BLS (7 close-ended questions). Results: Surprisingly, none of the 265 participants had complete knowledge of BLS and CPR. They lacked in basic knowledge of this important lifesaving protocol. The students and interns also were unaware of basic and applied knowledge of BLS, which shows the necessity of its inclusion in BDS curriculum. Conclusion: The understanding of lack of knowledge and awareness about BLS and CPR is alarming. Its inclusion in curriculum, training, and periodic re-training of dental undergraduates, interns, postgraduates, academicians, and practitioners is necessary.","PeriodicalId":56210,"journal":{"name":"Indian Journal of Dental Sciences","volume":"13 1","pages":"241 - 244"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47491653","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}

Background: Ceramic veneers is one of the conservative esthetic treatment modality in dentistry. Success of veneer is very much dependent on the design preparation. Materials and Methods: Thirty selected teeth were categorized within three groups of 10 each with varying design preparations. After mounting the specimens, the incisal reduction was done, and porcelain laminate veneers were fabricated. Then cementation of the veneers was done with resin-cement, and fracture load was applied and recorded. Results: Multiple comparisons were done using post-hoc Tukey's test and modality of failure of veneers among the different designs were done using Chi-square test with the level of significance fixed at 0.05. Conclusion: Ceramic veneers preparation design including1 mm incisal reduction along with 1 mm of palatal-chamfer height revealed greater fracture toughness in contrast to incisal-reduction 1 mm along with butt-joint preparation design.
