Observation and identification of porcelain teeth color

Selection of proper porcelain shade and color matching to the natural dentition is continuously one of the most perplexing and frustrating factors in fixed prosthodontics. A total of 4172 porcelain restorations were collected and categorized according to the Vita Lumin shade guide and the author's view point. After calculating and summing up the data, we found the most frequently used color is reddish-brown, and the least frequently used color is grey-brown. The results suggested a reference of porcelain shade for each tooth. The ability of the dentist in shade selection was not as predicted. Only 50% correct answers were obtained and 19.4% gave completely wrong answers. So we suggest that our data of porcelain color could be used as a reference. Another suggestion is that dentists should have color training in school and it should be a core course of prosthetic dentistry.     

Fixed prosthodontics clinical unit completions in an undergraduate curriculum: A 10-year retrospective study

Introduction

Providing undergraduate dental students with a range of clinical experiences in fixed prosthodontics procedures is an important component of dental education. The aim of this retrospective study was to analyse the types of laboratory-fabricated fixed prosthodontics clinical units completed by undergraduate students over 10 consecutive years and determine any significant trends.

Materials and Methods

The fixed prosthodontics treatment registers from 2012 to 2021 were reviewed and the different types of completed fixed prosthodontics units and total number of fixed prosthodontics units were recorded for each year. Completed units were categorised according to the type of restoration and expressed in whole numbers and as a percentage of the total number of units completed in each year. The data were presented in table and graph form. Mann-Kendall tests were performed to statistically analyse for trends in the different restoration types.

Results

Throughout all study years, porcelain bonded to metal (PBM) crowns (48.25%, range 35.70%–59.91%) were the most frequently completed fixed prosthodontics unit followed by full gold crowns (FGC) (20.84%, range 14.89%–27.30%) and all-ceramic crowns (ACC) (12.70%, range 3.67%–24.41%). Collectively, PBM, FGC and ACC comprised 81.80% of all completed fixed prosthodontics units. There were observed trends of increased use of all types of all-ceramic containing restorations, all types of all-gold containing restorations, all types of partial coverage restorations and specifically ceramic onlays and gold onlays. There were observed trends of reduced use of cast gold post-cores and all types of bridges.

Conclusion

PBM crowns were the mainstay laboratory-fabricated fixed prosthodontic unit completed over 10 years of undergraduate student fixed prosthodontics clinical practice.

Impact of prosthetic care on oral health related quality of life

Patients' perception of oral health can be characterized by Oral Health Related Quality of Life (OHRQoL). Therefore, it should be able to be used to measure their perceived benefits of prosthodontic treatment. Oral Health Impact Profile (OHIP) is one of the technically most sophisticated and most widely used instruments measuring OHRQoL. The aim of this study was to measure the impact of prosthodontic treatment on Oral Health Related Quality of Life. The Hungarian version of OHIP (OHIP-H 53) was applied for a sample of 63 prosthodontic patients at baseline, and at 1 as well as at 6 and 12 months following treatment. OHRQoL impairment is characterized by OHIP-H 53 scores. A linear regression model was used to estimate the rate of improvement of OHRQoL in different prosthodontic treatment groups (FPD, RPD and CD) at baseline and at follow-ups. OHRQoL improved rapidly within 1 month after treatment (76% of patients) and it underwent further but moderate improvement within the following 6 to 12 months after treatment in subjects with fixed, removable and complete dentures (90%) as indicated by the reduced OHIP-H scores. The largest improvement was observed in patients treated with fixed prosthodontics. Patients receiving removable or complete dentures had poorer OHRQoL than respondents treated with fixed prosthodontics. It can be concluded that OHRQoL can be improved by prosthodontic treatment, especially by using fixed prosthodontics. Besides considering clinical factors in prosthodontics, subjective conditions should also be involved in treatment planning in order to achieve a higher rate of acceptance of prosthetic care by the patient.     

以剩余牙本质壁状况指导大面积牙体缺损修复方式的选择

大面积牙体缺损患牙的治疗往往涉及多个学科，是临床上常见的难题。口腔修复技术、牙周冠延长术和根管治疗技术的不断发展为大面积牙体缺损患牙的治疗和修复提供了技术支持，使得更多的天然牙得以保留。尽管国内外学者逐渐认可剩余牙体组织状况影响修复方案这一理念，但大面积牙体缺损修复方式的临床选择仍缺乏系统的阐述。笔者作为口腔修复专科医生，通过与牙周科和牙体牙髓科专家共同探讨，提出一种以剩余牙本质壁状况为依据来选择修复方式的具体原则，并展示1例应用此原则完成治疗的临床病例，以期为临床上大面积牙体缺损患牙的诊治提供指导。     

联冠固定松动基牙后可摘义齿修复肯氏Ⅰ类牙列缺损的临床疗效观察

目的:分别用烤瓷联冠固定基牙和连续高位卡环稳定基牙,利用可摘局部义齿(removable partialdenture,RPD)修复双侧磨牙缺失,比较两者间的临床疗效。方法:选取肯氏Ⅰ类牙列缺损近缺失端基牙I-II度松动病例40例,在进行完善的牙周基础治疗后,分别采用烤瓷联冠固定基牙和连续高位卡环稳定基牙,行可摘局部义齿修复。术后复查,随访1-5年,通过比较患者的主观感受和临床检查结果进行疗效评价。结果:烤瓷联冠组5年临床成功率高于连续高位卡环组,两组患者的满意率、牙周菌斑指数、牙周袋探诊深度、临床附着水平、探诊后出血指数、牙槽骨支持指数差异有统计学意义(P<0.05)。结论:对肯氏I类牙列缺损伴前磨牙松动的患牙,经完善的牙周治疗后,烤瓷联冠固定松动基牙后行可摘局部义齿修复可获得较好的疗效。
