Traumatic injury to anterior teeth is frequent in children and adolescents owing to an active lifestyle. Proclined maxillary incisors are more prone to fracture due to their location in the oral cavity. Complicated crown root fractures present endodontic, restorative and aesthetic challenge and requires a multidisciplinary treatment approach to achieve predictable success. This case report describes, multidisciplinary management of such complicated crown root fractures following traumatic injury.

Who is an Oral & Maxillofacial Surgeon? 谁是口腔颌面外科医生?
Pub Date : 2022-06-20 DOI: 10.21276/ujds.2022.8.2.24
Prof. Sarwar Hashmi
During World War I, the large number of destructive facial wounds led to an increased demand for facial surgeons. At that time, the specialties of plastic surgery and oral and maxillofacial surgery did not exist and very few general surgeons were prepared to treat these patients. Instead of being surgically reconstructed, deformed faces were covered by masks. To address this demand, the American Society of Oral Surgeons and Exodontists was established in 1921. This name was used until 1946, when it was replaced by the American Society of Oral Surgeons. In 1975, the name was changed to the American Association of Oral and Maxillofacial Surgeons (OMS).
在第一次世界大战期间,大量的破坏性面部伤口导致对面部外科医生的需求增加。当时,整形外科和口腔颌面外科的专科还不存在,准备治疗这些患者的普通外科医生很少。变形的脸不是通过手术重建,而是用口罩遮住。为了满足这一需求,美国口腔外科医生和牙医师协会于1921年成立。这个名字一直使用到1946年,后来被美国口腔外科学会取代。1975年,更名为美国口腔颌面外科医师协会(OMS)。

The keratocystic odontogenic tumor (KCOT) is regarded as the most aggressive and recurrent tumor of all. The lesion does not pose any clinical symptoms until significantly large in size. The different treatment modalities are always a matter of dilemma as to which one would yield good results with less recurrence. A Conservative treatment approach for moderately large lesions such as marsupialization and decompression was carried out in this case with regular follow-up sessions. The aim of this case report is to treat cases of KCOT with a conservative surgical approach.
角化囊性牙源性肿瘤(KCOT)被认为是最具侵袭性和复发性的肿瘤。除非病变明显变大,否则不会引起任何临床症状。不同的治疗方式总是一个进退两难的问题,即哪一种治疗方式会产生良好的效果,减少复发。对于中等大小的病变,采用保守治疗方法,如有袋化和减压,并定期随访。本病例报告的目的是用保守的手术方法治疗KCOT病例。

Aim and objective The study was aimed to comparatively evaluate the effect of different methods of cleaning and preparation of occlusal surfaces on microleakage of pit and fissure sealant. Materials and method: Eighty (80) sound extracted premolars served as samples and were divided into four categories according to the method of cleaning and preparation of occlusal surfaces. Prior to sealant placement. The groups were: A Dry Brush, B Pumice Slurry Air Polishing and D Prophylaxis Paste. In each group, subsequent to cleaning of occlusal surfaces with the method assigned to, pit and fissure sealant was applied. The samples were then kept in an incubator, thermocycled and then immersed in methylene blue dye. Each tooth was sectioned longitudinally into two halves and observed under stereomicroscope for microleakage using a criteria given by Cooley et al. Statistical analysis: Discrete microleakage score of groups is summarized in number (n) and percentage (%).Result: Comparing the microleakage score of four groups, χ2 test showed significantly different microleakage score among the groups (χ2 =33.96, P <0.001). Conclusion: Microleakage score showed both pumice slurry (Group B) and especially air polishing (Group C) to be significantly more superior than prophylaxis paste (Group D) and dry brush (Group A).

Introduction: Examining the tooth is considered as foremost segment in research in the field of oral biology and oral pathology. For studying various structures like enamel, dentin and cementum, ground section of teeth is used, while decalcified sections of tooth are used for studying the soft tissues. Objective: The present study was aimed at exploring the normal structures of hard tissue parts of the teeth where partially decalcified ground sections were stained them with routine hematoxylin and eosin stain. Methodology: For the present study, a total of 30 extracted teeth were collected. The freshly prepared ground sections were partly decalcified by putting ground sections of teeth in 10% nitric acid for a time period of 20- 25 seconds. After this, the ground sections of teeth are washed in tap water. The partly decalcified ground sections of teeth were stained with routine hematoxylin and eosin staining procedure and were mounted on clean glass slides using DPX mounting media. The sections were then analyzed for various histological structures under the microscope. Results: When hematoxylin and eosin stained partially decalcified ground sections of teeth were viewed under light microscope, variety of histological structures appeared as stained, while some structures did not take stain and remain unstained. Conclusion: After preparing and staining the ground section of teeth by our method, we hope that it would be of great help for undergraduate students and to some extent the research scholars to understand the various structures of the teeth in a better and easy way.
口腔生物学和口腔病理学研究的前沿是对牙齿的检查。为了研究牙釉质、牙本质、牙骨质等各种结构,我们使用牙齿的磨碎部分,而牙齿的脱钙部分则用于研究软组织。目的:用常规苏木精和伊红染色法对部分脱钙的牙基底切片进行染色,观察牙硬组织部分的正常结构。方法:本研究共收集30颗拔牙。通过将牙齿磨碎的部分放在10%的硝酸中20- 25秒的时间,新制备的磨碎部分部分脱钙。之后,用自来水清洗牙齿的地面部分。牙齿部分脱钙的地面切片用常规苏木精和伊红染色方法染色,用DPX贴载介质贴载于干净的玻璃载玻片上。然后在显微镜下分析切片的各种组织学结构。结果:苏木精和伊红染色部分脱钙牙基底切片光镜下可见染色后的多种组织结构,部分结构未染色,未染色。结论:通过我们的方法制备和染色牙齿的地面切片,希望对本科生和一定程度上的研究学者更好、更容易地了解牙齿的各种结构有很大的帮助。

Conservative Management of Unicystic Ameloblastoma- A Case Report 单囊性成釉细胞瘤的保守治疗1例
Pub Date : 2022-04-30 DOI: 10.21276//ujds.2022.8.3.12
S. Agarwal
Ameloblastoma is the most common benign odontogenic tumor of the jaws that constitutes about 1% of all cysts and tumors of the jaws1,2. It is generally a painless, slow growing, locally aggressive tumor causing expansion of the cortical bone, perforation of the lingual or the buccal cortical plate and infiltration to the soft tissues. It has peak incidence in third and fourth decade of life but can be found in any age group with equal gender predilection (1:1)1,5. The relative frequency of mandible to maxilla is reported to be varying from 80% -20% to 99–1%. In the mandible majority of Ameloblastoma are found in the molar ramus region1,3. In a conventional radiograph, Ameloblastoma can present as either unilocular or multilocular corticated radiolucency. The bony septae results in a honey comb, soap bubble or tennis racket appearance. In some places, cortical plates are spared and expanded where as in other region they are destroyed; root resorption is a common finding6. Buccal and lingual cortical plate expansion is more common in Ameloblastoma than in other tumour7. Conventional radiograph is sufficient for small mandibular lesions but maxillary lesions and extensive lesions require CBCT, CT and MRI to establish the extent of the lesion7. The challenge in managing Ameloblastoma is by attaining complete excision and reconstruction of the defect when the tumor is large. Ameloblastoma is treated by enucleation, curettage or surgical excision depending on size and type of the lesion and conservative therapy also. This report gives a comprehensive knowledge regarding the conservative therapy using a  Iodoform and paraffin paste which has been a boon in treatment of odontogenic tumor.
成釉细胞瘤是颌骨最常见的良性牙源性肿瘤,约占颌骨所有囊肿和肿瘤的1% 1,2。它通常是一种无痛,生长缓慢,局部侵袭性肿瘤,引起骨皮质扩张,舌或颊皮质板穿孔和软组织浸润。它在生命的第三和第四个十年发病率最高,但可以在任何年龄组中发现,性别偏好相同(1:1)1,5。据报道,下颌骨与上颌骨的相对频率从80% -20%到99-1%不等。在下颌骨,大多数成釉细胞瘤发生在磨牙支区。在常规x线片上,成釉细胞瘤可以表现为单室或多室的皮质透光度。骨性隔形成蜂巢、肥皂泡或网球拍的外观。在某些地方,皮质板块被保留并扩展,而在其他地区,它们被破坏;牙根吸收是一种常见的发现。颊部和舌部皮层板扩张在成釉细胞瘤中比在其他肿瘤中更常见7。常规x线片对下颌小病变就足够了,但上颌病变和广泛病变需要CBCT、CT和MRI来确定病变的范围7。治疗成釉细胞瘤的挑战是当肿瘤很大时,如何实现完全切除和重建缺陷。根据病变的大小和类型,成釉细胞瘤的治疗方法有去核、刮除或手术切除,也有保守治疗。本报告全面介绍了碘仿石蜡膏在牙源性肿瘤治疗中的应用。
{"title":"Conservative Management of Unicystic Ameloblastoma- A Case Report","authors":"S. Agarwal","doi":"10.21276//ujds.2022.8.3.12","DOIUrl":"https://doi.org/10.21276//ujds.2022.8.3.12","url":null,"abstract":"Ameloblastoma is the most common benign odontogenic tumor of the jaws that constitutes about 1% of all cysts and tumors of the jaws1,2. It is generally a painless, slow growing, locally aggressive tumor causing expansion of the cortical bone, perforation of the lingual or the buccal cortical plate and infiltration to the soft tissues. It has peak incidence in third and fourth decade of life but can be found in any age group with equal gender predilection (1:1)1,5. The relative frequency of mandible to maxilla is reported to be varying from 80% -20% to 99–1%. In the mandible majority of Ameloblastoma are found in the molar ramus region1,3. In a conventional radiograph, Ameloblastoma can present as either unilocular or multilocular corticated radiolucency. The bony septae results in a honey comb, soap bubble or tennis racket appearance. In some places, cortical plates are spared and expanded where as in other region they are destroyed; root resorption is a common finding6. Buccal and lingual cortical plate expansion is more common in Ameloblastoma than in other tumour7. Conventional radiograph is sufficient for small mandibular lesions but maxillary lesions and extensive lesions require CBCT, CT and MRI to establish the extent of the lesion7. The challenge in managing Ameloblastoma is by attaining complete excision and reconstruction of the defect when the tumor is large. Ameloblastoma is treated by enucleation, curettage or surgical excision depending on size and type of the lesion and conservative therapy also. \u0000This report gives a comprehensive knowledge regarding the conservative therapy using a  Iodoform and paraffin paste which has been a boon in treatment of odontogenic tumor.","PeriodicalId":100856,"journal":{"name":"King Saud University Journal of Dental Sciences","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81836798","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}
