“…11 In addition, while Ong et al showed that caries and periodontal disease were of equal importance, the majority of their sample was aged less than 40 years. 13 Thus, comparison of tooth extraction data between different countries is fraught with difficulty.…”

lous at these time points fell from 54% to 33% to 13%. It seems likely, therefore, that the reasons for tooth loss in Scotland might have changed in the 15 years since they were first determined.In order to facilitate planning for dental health services and to develop strategies to continue the reduction in tooth loss it is important to identify the factors which have resulted in such loss.The aim of this study was to determine the current reasons for tooth extractions in Scotland and their relative importance. MethodThe Scottish Dental Practice Board was asked to provide the names and addresses of every fourth dentist on its list, stratified by health board area. The aim was to obtain a sample of 25% of Scottish general dental practitioners. Emergency only clinics were excluded. These dentists were forwarded a covering letter explaining the nature of the study, a record form and a reply paid envelope. They were asked to record permanent tooth extractions for one working week on one single form. For each patient having one or more teeth extracted, the number, type and reason for each extraction were recorded. Records were obtained only for those patients having an extraction.After an interval of 1 month a second wave of forms (with a suitably modified covering letter) was sent out to the non-respondents. After a further month all the remaining non-respondents were telephoned by one of the authors and encouraged to participate.To facilitate comparison with the 1984 study the same extraction criteria were used and are shown in Table 2. The dentists were asked to give only one reason for each tooth removed and to record each patient's age, gender and dental attendance pattern. Regular attendance was defined as attendance at the surgery in the past 2 years for routine examination. Patients attending solely for pain relief and patients attending for the first time were deemed irregular attenders. ResultsA total of 479 forms were issued. It became clear from some of the forms returned that a number of the dentists receiving the form were not eligible to complete it (13 were orthodontists or community dentists). Further, 41 forms could not be completed because the intended recipients had either left the practice or were on maternity leave or were deceased. Thus 425 forms were received by general dental practitioners. A total of 352 forms were completed and returned. This represents 73.5% of the 479 forms originally issued or an 82.8% response rate from the 425 eligible dentists who received a form. This gave a final sample of about 20% of Scotland's general dental practitioners. There are 13 health board areas in Scotland and there were no significant differences in the response rate for each health board area.All targeted dentists were contacted either by letter or telephone in the course of the study and an attempt was made to clarify the reasons for non-participation of eligible dentists. These included lack of time or lack of interest, working part time only and being on holiday.Of the 352 returned forms, 2 were co...

“…Fracture as a sequela of caries has been shown to be one of the main reasons for permanent tooth extractions [19][20][21][22][23] . In the same connection, the number of tooth extractions can be reduced effectively by preventing fractures, especially vertical root fracture.…”

“…Nonetheless, root fracture is one of the major causes leading to tooth extraction. Hence, it is highly desirable to prevent fractures or limit the fracture line to the suprabony area [19][20][21][22][23] . Some researchers have reported methods of reinforcing thin root canal dentin wall with resin composites [24][25][26][27] .…”

This study was aimed at evaluating the fracture resistance of structurally compromised roots restored with four different post and core systems. Thirty-two bovine roots were uniformly shaped to simulate human mandibular premolar roots. The roots were divided into four groups based on the type of restoration: cemented cast post and core (Group MC), resin composite build-up (Group CR), resin composite and prefabricated glass fiber post build-up (Group FRC), and thick-layer dual-cured resin composite-reinforced smalldiameter tapered cast post and core (Group CRM). After a static loading test, the failure mode and fracture resistance were recorded. Group CRM (719.38±196.73 N) exhibited a significantly high fracture resistance compared with the other groups (Group MC: 429.56±82.43 N; Group CR: 349.56±66.21 N; Group FRC: 398.94±112.71 N; p<0.05). In conclusion, Group CRM exhibited better mechanical properties for structurally compromised roots with no ferrules, although all types of restorations showed non-restorable fracture modes.

“…6 The two most common causes of tooth loss in Asian population are dental caries and periodontal disease. 7 Secondary reasons for tooth loss are restricted access to dental services, health systems, and lack of oral health care. 8 Rural India accounts for 83.3% of the total population of India which accounts for majority of the population.…”
