Background

Extraction of wisdom tooth is one of the most common surgical interventions, as it is more prone for impaction. Due to the pain and anxiety associated with the procedure, it is common to do this procedure under conscious sedation. However unexpected events do occur during the procedure and one such complication along with the prompt management is discussed here.

Case report

This case report details an unusual occurrence of a third molar tooth slipping during dental extraction and becoming lodged at the base of the vocal cords. The patient, a 52-year-old man with a history of hypertension, underwent the procedure under conscious sedation. The case report highlights the importance of preparedness and multidisciplinary coordination in managing rare complications during dental procedures under conscious sedation. The accidental aspiration of a molar tooth into the airway required prompt and effective intervention, using dexmedetomidine for sedation, fibre-optic bronchoscopy for visualization, and a range of retrieval instruments. Using video-assisted laryngoscopy and fibre-optic laryngoscopy proved indispensable in locating and safely retrieving the foreign body without resorting to more invasive procedures.

Conclusion

This case highlights the importance of anaesthesiologist's role in emergency management and comprehensive preparedness in dental practice.

Background

Previous studies revealed diabetes mellitus subjects tend to have persistent apical periodontitis. Regenerative stem cells therapy through endodontic procedure is hoped to be a solution. This study assessed bone regeneration in diabetic rats with apical periodontitis through histopathological analysis of osteoblasts and immunohistochemical analysis of runt-related transcription factor 2 (Runx2) and Osterix.

Methods

Diabetes mellitus and apical periodontitis was induced on 20 rats. Apical periodontitis was induced on mandibular right first molars under anesthesia. The teeth were left open for 7 days following access cavity and pulp extirpation, then the rats’ teeth were endodontically treated and randomly allocated into 4 groups (5 rats per group). The first and second groups was ended at 30 days (C30) and 60 days (C60) and labelled as control. The third and fourth groups was given umbilical cord mesenchymal stem cells and ended at 30 days (T30) and 60 days (T60). The osteoblasts, Runx2 and Osterix were analyzed. ANOVA and Tukey HSD tests were used for analysis. Differences with p values < 0.05 were considered significant.

Results

The number of osteoblasts in the apical area in control groups (C30 and C60) and treatment groups (T30 and T60) showed a significant increase (p < 0.05). The expressions of Runx2 and Osterix in osteoblasts showed a significant increase among the control (C30 and C60) and treatment groups (T30 and T60) (p < 0.05).

Conclusion

Umbilical cord mesenchymal stem cells improve bone regeneration in diabetic animal model with apical periodontitis, in terms of osteoblasts, Runx2 and Osterix.

Objective

This study aimed to compare a direct conventional 3D digital technique vis a vis a hybrid method in measuring palatal volume.

Materials and methods

Thirty maxillary casts were obtained from the records of patients undergoing orthodontic treatment and pre-conceived boundaries of the palatal vault were marked. Sample was categorised into Group I (Volume estimation using CBCT scan) and Group II (Volume estimation using hybrid method). Estimation of the palatal volume in this study involved filling the volume of interest in the palate with gypsum (Type IV) stone material and carefully carving according to the boundaries and anatomy. This positive reproduction of the palatal space was safely retrieved and then scanned in the NewTom GiANO HR Cone Beam Imaging setup. The obtained scan was analysed in NNT Software Version 3.10 and the volume of the palate was calculated. Two experienced orthodontists carried out the measurements to evaluate the inter and intra-observer reliability. This was compared with the palatal volume calculated by the conventional digital method using CBCT in the NNT Software.

Result

This study showed a consistent and narrow range of the confidence interval for palatal volume. Hence, the sample size was sufficient and had good precision. Considering a 95 % confidence interval, the intra-class correlation coefficient was robust (>0.9) for all measurements calculated by the hybrid method suggesting a high reliability. The mean difference in measurement of palatal volume (Group I vs, Group II) was 1.37 + 0.64 mm3 and the difference was statistically insignificant. Statistical t-test conducted between the two methods showed a p-value of 0.34, implying no statistically significant difference between the two methods.

Conclusion

The hybrid method for evaluating the palatal volume is simple, accurate and comparable to the conventional digital method. A major advantage of this simplified method is that the patient is not exposed to any radiation of CBCT. Also, need for a specific skillset for digitally measuring the palatal volume is not a must.

材料和方法从接受正畸治疗的患者记录中获取 30 个上颌骨铸模，并标记出预先设想的腭穹边界。样本被分为第一组（使用 CBCT 扫描估算体积）和第二组（使用混合方法估算体积）。在这项研究中，腭部容积的估算是用石膏（IV 型）石料填充腭部感兴趣的容积，并根据边界和解剖结构仔细雕刻。腭部空间的正面再现被安全提取出来，然后在 NewTom GiANO HR 锥形束成像装置中进行扫描。扫描结果通过 NNT 软件 3.10 版进行分析，并计算出腭部的体积。由两名经验丰富的正畸医生进行测量，以评估观察者之间和观察者内部的可靠性。结果这项研究显示，腭部体积的置信区间一致且范围较窄。因此，样本量充足且精确度高。考虑到 95% 的置信区间，混合法计算出的所有测量值的类内相关系数都很稳健（0.9），表明可靠性很高。腭部体积测量的平均差异（第一组与第二组）为 1.37 + 0.64 mm3，差异在统计学上不显著。在两种方法之间进行的统计 t 检验显示 p 值为 0.34，这意味着两种方法之间没有显著的统计学差异。这种简化方法的主要优点是患者不会受到 CBCT 的任何辐射。此外，数字化测量腭部容积不需要特定的技能。

Objectives

Intraoral scanners used for the fabrication of milled and 3D-printed complete dentures simplify the procedure. However, its effectiveness in recording the functional peripheral seal area needs to be researched. Therefore, this study aims to assess the retention of conventional, milled and 3D-printed denture bases made from conventional impression technique and digital scans in different types of post palatal seal area.

Material and method

Completely edentulous participants were divided into group A and group B based on type of posterior palatal seal area. Each group received three denture bases fabricated using compression molding, milling and 3D printing. The retention was evaluated using a digital dynamometer at 45° and 90° inclination.

Results

The ANOVA test revealed statistically significant difference in the retention of denture bases fabricated using three different techniques. When compared between the three groups at 45 and 90°, statistically significant difference in the retentive values between the control and other two groups were observed.

Conclusion

All three of the fabrication processes have retention that falls within a clinically acceptable range. 3D printed dentures had better adaptation on the PPS area whereas the milled dentures had a better peripheral seal although the conventional process showed highest retention values.

目的口内扫描仪用于制作铣制和三维打印的全口义齿，简化了制作过程。然而，它在记录功能性周边密封区方面的有效性还有待研究。因此，本研究旨在评估使用传统印模技术和数字扫描技术制作的传统义齿基托、铣制义齿基托和三维打印义齿基托在不同类型的腭后封闭区的固位情况。每组接受三个使用压缩成型、铣削和三维打印技术制作的义齿基托。结果方差分析检验显示，使用三种不同技术制作的义齿基托的固位情况存在显著的统计学差异。三组在 45° 和 90° 倾角下的固位值比较结果显示，对照组和其他两组的固位值在统计学上有显著差异。三维打印义齿对 PPS 区域的适应性更好，而研磨义齿的周边密封性更好，尽管传统工艺显示出最高的固位值。

Background

For the clinician to conveniently perform an extensive oral examination, it is required to have a known normal range of maximum mouth opening (MMO). This study aims to establish a standard for calculating the normal range of mouth opening in the adult population of North India. The results of this research will have clinical implications for the treatment and diagnosis of diseases that affect the mouth opening in adults, either directly or indirectly.

Aim

To evaluate mean mouth opening in North Indian population and establish their correlation with age and gender.

Method

662 adults from North Indian population, 317 males and 345 females in the age range of 18–80 years were evaluated on their consent. Maximum mouth opening was measured using calibrated vernier calliper scale. This study was conducted in the Department of Periodontology, Faculty of Dental Sciences, King George Medical University, Lucknow.

Results

Males exhibited a higher mean MMO of 48.0 mm compared to females, who had a lower mean MMO of 45.1 mm among North Indian population of the country. In the statistical comparison of MMO between males and females within each age group, the results showed no significant differences.

Conclusion

Mouth opening of females is less than males in all age groups and it seems to decrease with age in all age groups in both males and females. The variability of MMO with age appears statistically similar for both genders.

背景为了方便临床医生进行广泛的口腔检查，需要了解最大张口度 (MMO) 的正常范围。本研究旨在为北印度成年人口腔张开的正常范围建立一个计算标准。本研究的结果将对直接或间接影响成人张口的疾病的治疗和诊断产生临床影响。方法在征得本人同意后，对来自北印度的 662 名成人进行评估，其中男性 317 人，女性 345 人，年龄范围在 18-80 岁之间。使用校准过的游标卡尺测量最大张口度。这项研究在勒克瑙乔治国王医科大学牙科学院牙周病学系进行。结果在该国的北印度人口中，男性的平均最大口腔张开度为 48.0 毫米，高于女性的 45.1 毫米。结论在所有年龄组中，女性的张口率都低于男性，而且在所有年龄组中，男性和女性的张口率似乎都随着年龄的增长而下降。从统计学角度看，女性和男性的张口率随年龄的变化相似。

Introduction

The degree of conversion of dentin bonding agents contributes to the success of final restorations in adhesive dentistry. It is clinically relevant, as it is directly related to the overall bond strength that maintains these restorations in place and prevents marginal deterioration. However, Matrix metalloproteinases (MMPs) present within the dentin substrate have been known to have a deleterious effect on the bond stability, due to their collagenolytic activity. Inhibition of the effects of MMPs has been studied, and the use of a pre-treatment protocol that includes MMP inhibiting agents before bonding procedures has been explored, and has been found to increase bond strengths. However, the effect that MMP inhibitors have on dental adhesives has not yet been explored, particularly when being used in caries-affected-dentin (CAD). This study aims to report the degree of conversion of an 8th-generation dentin bonding agent in sound dentin (SD) vs caries-affected dentin after pre-treatment using MMP inhibitors.

Materials & methods

60 dentin discs were divided into groups of sound and affected dentin, and pretreated with either Cranberry extract or mulberry extract was applied to half of the discs in each group, followed by the application of an eight-generation bonding agent to the pre-treated discs, which were then light cured. The degree of conversion of the adhesive was calculated using ATR-FTIR spectroscopy.

Results

The degree of conversion was found to be the highest in the samples of sound dentin which were pre-treated with Mulberry extract.

Conclusion

Pre-treatment of the dentin with MMP inhibitors led to an increase in the degree of conversion in sound dentin but not in CAD.

导言牙本质粘接剂的转化程度有助于粘接牙科中最终修复体的成功。它与临床相关，因为它直接关系到维持这些修复体就位和防止边缘退化的整体粘接强度。然而，存在于牙本质基质中的基质金属蛋白酶（MMPs）由于具有溶解胶原的活性，对粘接稳定性有有害影响。人们已经对抑制 MMPs 的作用进行了研究，并探索了在粘接程序前使用包括 MMP 抑制剂在内的预处理方案，结果发现这种方法可以提高粘接强度。然而，MMP 抑制剂对牙科粘合剂的影响尚未得到探讨，尤其是在受龋齿影响的牙本质（CAD）中使用时。本研究旨在报告使用 MMP 抑制剂进行预处理后，第八代牙本质粘接剂在健全牙本质（SD）与龋坏影响牙本质中的转化程度。使用 ATR-FTIR 光谱计算粘合剂的转化程度。结果发现，使用桑葚提取物预处理的健全牙本质样本的转化程度最高。

Varying proportions of the extract was incorporated into polymethyl methacrylate (PMMA) denture base resin and the anti-adherent effect was investigated.

Methods

An in-vitro study was performed after pure extract was obtained from Lavandula angustifolia (LA) flowers using a solvent based hot extraction process. Chromatographic analysis and computational molecular docking were done to analyze its phytoconstituents with potential target-ligand bond. Tests of antimicrobial susceptibility, minimum inhibitory concentration, minimum bactericidal and fungicidal dosages and in-vitro cytotoxicity were performed. Different proportions of LA extract (0, .5, 1.0, 1.5, and 2.0 %) were added to PMMA resin to assess anti-adherence property. Obtained data were statistically analyzed with One-way ANOVA followed by Tukey post-hoc tests.

Results

The reports revealed significant antimicrobial susceptibility against the test pathogens compared to control drugs (P > 0.05). A minimum concentration of .02 mg of lavender extract inhibited microbial growth with low cytotoxicity (P < 0.05). The highest anti-adherent activity was observed in the .5 % LA-incorporated PMMA resin group (P = 0.0001).

Conclusions

Incorporating lavender extract into denture base resin demonstrated promising antimicrobial properties. This investigation encourages further research to understand its effects on mechanical and physical properties of reinforced dental resins.

研究目的：确定薰衣草（真薰衣草提取物）对白色念珠菌、变异链球菌和金黄色葡萄球菌病原体的抗菌效果。将不同比例的萃取物加入聚甲基丙烯酸甲酯（PMMA）义齿基底树脂中，研究了其抗粘连效果。色谱分析和计算分子对接分析了其植物成分与潜在目标配体的结合。进行了抗菌敏感性、最小抑菌浓度、最小杀菌和杀真菌剂量以及体外细胞毒性测试。将不同比例的 LA 提取物（0、.5、1.0、1.5 和 2.0 %）添加到 PMMA 树脂中，以评估抗粘附性。结果报告显示，与对照组药物相比，LA 提取物对测试病原体具有显著的抗菌敏感性（P > 0.05）。最低浓度为 0.02 毫克的薰衣草提取物可抑制微生物生长，但细胞毒性较低（P< 0.05）。结论在义齿基底树脂中加入薰衣草提取物具有良好的抗菌特性。这项调查鼓励人们进一步研究薰衣草提取物对增强型牙科树脂的机械和物理特性的影响。

Objective

To identify the trends of the top 100 cited articles on economic evaluation in preventive oral health programs.

Methods

Top 100 papers involving economic evaluation or cost analysis of preventive oral health programs were selected by querying Scopus and Web of Science databases. Bibliometric analysis was performed using the Bibliometrix tool in R Studio. Performance analysis and science mapping were performed for these 100 articles. Performance analysis included publication-related metrics, citation-related metrics, and citation-publication-related metrics. Science mapping provided information on citation analysis, co-citation analysis, bibliographic coupling, co-word analysis, and co-authorship details.

Results

The total citation number of the top 100 most cited articles ranged from 4 to 98, with publication dates spanning from 1978 to 2023. The majority of articles (33.70 %) originated from the USA, while Community Dentistry and Oral Epidemiology stood out as the journal with the highest number of articles published in the top 100 (16 out of 100). Griffin PM emerged as the most cited author, based on the frequency measurement of the number of papers. Program data economic evaluation was the most commonly reported study design, and fluoridation programs were the most frequent topic. The most reported type of economic analysis performed in the articles was cost-effectiveness analysis.

Conclusion

The bibliometric analysis of the top 100 most-cited articles on economic evaluation of preventive oral health programs revealed the lacunae in the research literature on this topic. Therefore, preventive oral health programs should be economically evaluated to eliminate the disparity in resource allocation particularly in upper middle income and low-income countries.

Objective

To evaluate the pharyngeal airway width and hyoid bone position in children with class II malocclusion and a positive history of sleep problems.

Methods

60 children aged 8–12 years with skeletal class II malocclusion were segregated into two groups according to the existence of sleep problems: 30 participants with sleep disorders constituted the study group, while 30 participants without sleep disorders formed the control group. Pharyngeal airway space and hyoid bone position were evaluated via a clinical and radiographic examination.

Results

A significantly narrower upper pharyngeal airway width and decreased C3-H hyoid parameter was noted in children with sleep problems (p = 0.035, 0.012).

Conclusion

Both pharyngeal airway parameters and the hyoid bone parameters could be potential risk indicators while screening for sleep-disordered breathing in children.

方法根据存在睡眠问题的情况，将60名8-12岁骨骼Ⅱ类错颌畸形儿童分为两组：30名有睡眠障碍的儿童为研究组，30名无睡眠障碍的儿童为对照组。结果发现，有睡眠问题的儿童咽上气道宽度明显变窄，C3-H舌骨参数下降（p = 0.035，0.012）。结论在筛查儿童睡眠呼吸障碍时，咽气道参数和舌骨参数都可能是潜在的风险指标。

Background

Calcific metamorphosis in root canals is common and presents challenges in gaining access. Guided endodontics offers a solution to overcome these difficulties. The PriciGuide® system is a patented guided endodontic technique claiming superior precision compared to sleeve-based guides. This study aims to compare deviation between the PriciGuide® system and the guide with sleeve.

Methods

A patient with calcified canal underwent CBCT scanning to obtain a DICOM file. Using the DICOM file, 3D models were printed. The patient's cast was scanned to obtain an STL file. Using DICOM and STL files, the guide with sleeve was designed using BlueSkyBio software and 3D printed. The PriciGuide® system was obtained from Roots to Cusps® Private Limited. Access opening was performed using conventional method, guide with sleeve and guide without sleeve (PriciGuide® system).

Samples underwent radiograph scans to measure coronal, apical, and angular deviations, as well as procedural time.

Results

One-Way ANOVA and Post Hoc Bonferroni's test revealed that coronal, apical, and angular deviations were lowest in the guide without sleeve group. However, access opening times were similar in both guided technique groups.

Conclusions

The PriciGuide® system offers precise access cavity preparation for calcified canals, showing minimal deviation compared to the sleeve-based guides. It facilitates accurate root canal access regardless of the dentist's experience level. This study utilized 3D-printed teeth that do not fully replicate the complexities of natural teeth, further research is needed to validate the PriciGuide® system's performance on natural teeth and assess deviation using CBCT for a more comprehensive evaluation.

背景根管变形是一种常见现象，给进入根管带来了挑战。引导根管治疗为克服这些困难提供了一种解决方案。PriciGuide® 系统是一种获得专利的引导式根管治疗技术，与套筒式引导器相比，它具有更高的精确度。本研究旨在比较 PriciGuide® 系统与套筒式引导器之间的偏差。使用 DICOM 文件打印三维模型。扫描患者的石膏以获得 STL 文件。使用 DICOM 和 STL 文件，使用 BlueSkyBio 软件设计了带套筒的导板，并进行了三维打印。PriciGuide® 系统由 Roots to Cusps® 私人有限公司提供。使用传统方法、带套筒导板和不带套筒导板（PriciGuide® 系统）进行通路打开。样本接受放射线扫描，以测量冠状面、根尖和角度偏差以及手术时间。结果单向方差分析和事后Bonferroni检验显示，不带套筒导板组的冠状面、根尖和角度偏差最小。结论PriciGuide®系统可为钙化根管提供精确的通路洞预备，与套筒导向器相比，偏差最小。无论牙医的经验水平如何，它都能促进根管的精确进入。本研究使用的 3D 打印牙齿并不能完全复制天然牙齿的复杂性，因此需要进一步研究来验证 PriciGuide® 系统在天然牙齿上的性能，并使用 CBCT 评估偏差，以进行更全面的评估。
