RESUMEN Objetivo: Comparar la cantidad y características de las prótesis dentales removibles parciales y totales, en el servicio de odontología del Hospital Nacional de Geriatría y Gerontología, en el periodo de tiempo comprendido del 1 de enero 2005 al 31 de diciembre 2008, equivalentes a 326 expedientes. Se tomó la base de datos del servicio de odontología de consulta externa especializada de los pacientes atendidos de los años 2005 al 2008, en los cuales se entregaron un total de 2786 prótesis dentales removibles. Materiales y métodos: Con base en el dato anterior se seleccionó la muestra no aleatoria a conveniencia hasta alcanzar el tamaño de 599 prótesis entregadas, examinando 326 expedientes del periodo de enero del 2005 a diciembre del 2008, con un nivel de confianza de 99% y un error de muestreo de 0.0466. La recolección de datos se realizó por medio del programa Microsoft Excel donde se utilizó una tabla en la que se anotó el número de expediente, fecha de inicio y conclusión de prótesis, tipo de prótesis, cantidad y color de prótesis, edad, género y domicilio del paciente por distrito, cantón y provincia. El procesamiento se realizó por medio de estadística descriptiva utilizando cuadros y gráficos. Resultados: Se determinó que el mayor porcentaje de rango de edad de personas que solicitaron prótesis removibles fue de 62 a 65 años, independiente si eran prótesis totales o parciales, los pacientes que requirieron dos prótesis fueron 273 de 326, en su mayoría los pacientes solicitaron prótesis totales para un total de 372 de 599 prótesis entregadas. De la guía de color utilizada en el HRBC los colores más requeridos fueron los tonos claros blanco amarillentos que corresponde al número 62 y 65; de los expedientes analizados la mayoría de los pacientes residían en San José con un total de 200 pacientes. Se concluye que el mayor porcentaje de edentulismo que se presento es el edentulismo total con un 62%, la prótesis más utilizada es la prótesis total superior removible y en su mayoría los pacientes requieren dos prótesis, con respecto al color no es concluyente para este estudio debido a los datos no disponibles en los expedientes analizados.

ABSTRACT Objective: Compare the quantity and characteristics of partial and total removable dental prostheses, in the dentistry service of the National Hospital of Geriatrics and Gerontology, in the period from January 1, 2005 to December 31, 2008. The database of the specialized outpatient dentistry service of the patients treated from 2005 to 2008 was taken, in which a total of 2786 removable dentures were delivered. Materials and methods: Based on the previous data, the non-random sample was selected for convenience until reaching the size of 599 protheses of 326 files, with a confidence level of 99% and a sampling error of 0.0466. Data collection was carried out through the Microsoft Excel program where a table was used in which the file number, date of start and conclusion of the prosthesis, type of prosthesis, amount and color of prosthesis, age, gender and address were used of the patient by district, canton and province. The processing was carried out by means of descriptive statistics using tables and graphs. Results: It was determined that the highest percentage of the age range of people who requested removable prostheses was 62 to 65 years, the patients that required two prostheses were 273 of 326. In their majority, the patients requested total prostheses for a total of 372 of 599 prostheses delivered. Of the color guide used in the HRBC, the most requested colors were the light yellowish-white tones corresponding to the number 62 and 65; of the files analyzed, most of the patients resided in San José with a total of 200 patients. Conclusion: It is concluded that the highest percentage of edentulism that is presented is total edentulism with 62%, the most commonly used prosthesis is the removable upper total prosthesis and for the most part patients require two prostheses, with respect to color it is inconclusive for this study due to data not available in the analyzed files.

Association between Diabetes and the Use of Removable Dental Prostheses among the Korean Population.

BACKGROUND: A balanced nutrient intake is important for patients with diabetes. Even if individuals have the same number of residual natural teeth, there are large differences in the masticatory performance between edentulous sites restored with a fixed dental prosthesis, including dental implants, and those restored with a removable dental prosthesis. This study assessed whether the prevalence and control of diabetes differed based on the use of removable dental prostheses through an analysis of nationally representative data. METHODS: Overall, 8,155 individuals (3,525 men and 4,630 women) aged ≥ 50 years were included in this study and were classified into the following 3 groups: group 1, did not use any removable dental prostheses (NF); group 2, used removable partial dentures (RPD); and group 3, used removable complete dentures on at least 1 jaw (CD). The characterization of diabetic patients and glycemic control were analyzed and compared among groups. To determine the relationship between diabetes and the use of dental prostheses, multivariable logistic regression analysis was performed (P < 0.05). RESULTS: The adjusted odds ratios and 95% confidence intervals for diabetes in men participants in groups NF, RPD, and CD were 1 (reference), 1.165 (0.878-1.544), and 1.491 (1.034-2.151), respectively, after adjusting for confounding factors. Diabetes and glycemic control were significantly associated with the use of removable dental prostheses among men. CONCLUSION: The use of removable dental prostheses is a potential risk indicator for uncontrolled diabetes in Korean men adults, suggesting the need for a comprehensive approach to minimize the complications of diabetes mellitus.

Status of Tooth Loss and Denture Restoration in Chinese Adult Population: Findings from the 4th National Oral Health Survey.

OBJECTIVE: To investigate the status of tooth loss and denture restoration in Chinese adults, analyse the changing trend and provide fundamental data for oral health policy. METHODS: According to the protocol of the 4th National Oral Health Survey, a multistage stratified random cluster-sampling method was used to enrol adult subjects aged 35 to 44, 55 to 64 and 65 to 74 years in all 31 provinces, municipalities and autonomous regions of the mainland of China. The status of tooth loss and denture restoration was investigated. SPSS20.0 software was used for statistics analysis. RESULTS: Among the 13,464 subjects investigated, 13.8% had complete dentition, 84.4% had dentition defects, and 1.8% was edentulous. Urban subjects showed a significantly higher proportion of complete dentition than those in rural (P = 0.02), and males showed the statistically higher proportion of complete dentition than females (P = 0.01). The mean of remaining teeth was 26.1 ± 6.90, which in urban areas was significantly higher than in rural areas (P < 0.01). The means of remaining teeth were 29.6 ± 2.3, 26.3 ± 6.1, and 22.5 ± 8.7 in the 35 to 44, 55 to 64 and 65 to 74 age groups, respectively. The detection rate of fixed partial dentures (FPD) was statistically higher in urban than in rural areas and in males than that in females (P < 0.01). The detection rate of removable partial dentures (RPD) was statistically higher in urban areas than in rural locations (P < 0.01). However, the detection rates of irregular denture and unrepair of tooth loss were both significantly lower in urban than in rural areas (P < 0.01). The rate of restoration of tooth loss was 41.6% in Chinese adults. CONCLUSION: Although the tooth loss and denture restoration status recorded in the survey was improved compared with the results of 10 years ago, more efforts need to be made on strengthening oral health promotion, particularly for elderly people and those living in rural areas.

[Mental health of elderly and old people when using a complete dry dental prosthesis: myth or reality?] / Psikhicheskoe zdorov'e pozhilykh liudei pri pol'zovanii polnymi s''emnymi zubnymi protezami: mif ili real'nost'?

The study studied the ratio of 17 adults with complete loss of teeth and using complete removable acrylic dentures, to the disease, taking into account the degree of stability of dentures during chewing. To determine the type of patient's attitude toward the disease, a clinical test method was used to determine the type of attitude towards the disease, in which the clinical-psychological typology of patients' attitude to 'illness' was realized, which provides the possibility of determining one of the twelve types of response. It was found that when using complete removable dentures, regardless of age and sex, the types of attitude towards the disease were more often noted, with a marked disadaptive behavior with a predominantly intrapsychic orientation of the response to the disease, which was manifested by characteristic reactions such as irritable weakness, anxious, depressed, oppressed state. The use of the cream to fix the removable dental prostheses Corega allowed to improve the stability of complete removable dentures, to eliminate the pronounced phenomena of mental disadaptation, and to create realistic treatment settings for patients, to help restore social ties.

A short report on tooth replacement in an older suburban population in Nigeria.

OBJECTIVES: To determine: the knowledge of the participants about removable dentures, importance of tooth replacement; prevalence of tooth loss and denture use; and factors associated with its non-use among an elderly population in Nigeria. BACKGROUND: Tooth loss without replacement can impact negatively on the quality of life of the elders, thus making use of denture a basic requirement for those with partial or complete edentulous arches in developed countries. It is, however, not known if this is the case among elders in suburban Nigeria. MATERIAL AND METHODS: A cross-section of 392 consenting elderly participants aged ≥65 years residing at Idikan, Ibadan, Nigeria, were interviewed on their biodata, knowledge of removable denture and importance of tooth replacement, history of use of denture and reasons for non-use where applicable. Oral examinations for the presence of missing teeth and denture were conducted by an examiner. Data were analysed with SPSS and P value set at ˂.05. RESULTS: The mean age of the participants was 73 (SD = 9.2) years. About 39% of the participants believed that it was important to replace missing teeth, 56.0% had poor knowledge about tooth replacement options, and 47.7% had at least a missing tooth. Only 7.1% of those with missing teeth had them replaced and all were using removable acrylic partial dentures. Financial constraint was the main reason for non-replacement of missing teeth (80.1%). Age, gender, occupation before retirement, income, level of education and presence of physical impairment were associated with non-use of denture (P Ë‚ .05). CONCLUSION: Many elderly individuals had poor knowledge about removable dentures and the importance of tooth replacement. About half of the participants had full complement of teeth and only 7.1% of those with tooth loss reported denture wear. Major reasons for non-use of dentures were due to economic reasons.

Autopercepción de salud bucal en adultos mayores portadores de prótesis parcial removible acrílica / Self-perception of oral health in elderly with acrylic removable partial acrylic prosthesis

Introducción: el incremento de la población mayor de 60 años influye en que cada día acudan más personas a los servicios de prótesis en busca de rehabilitación, y en la mayoría de los casos no se adaptan a las nuevas condiciones. Objetivo: determinar la asociación entre algunos factores que influyen en la autopercepción de salud bucal en adultos mayores portadores de prótesis parcial removible acrílica. Métodos: investigación observacional descriptiva (enero-diciembre de 2013) en 150 adultos, seleccionados al azar, mayores de 60 años rehabilitados protésicamente. Se evaluaron las variables: edad, sexo, tipo de prótesis, niveles de escolaridad, experiencia anterior y tiempo de uso, en asociación con la autopercepción de salud bucal, medida esta mediante el índice de salud bucal geriátrico. Resultados: el 53 de los pacientes tenía entre 60 y 69 años y fue en los que se obtuvo la mayor frecuencia de autopercepción regular (49,3 por ciento). Los del sexo masculino (16 por ciento) fueron quienes tuvieron una mayor frecuencia de respuestas que coincidió con una autopercepción buena. Las mayores frecuencias de autopercepción mala correspondieron a los de nivel preuniversitario y universitario, quienes en conjunto sumaron el 19 por ciento, a los que tenían prótesis superior (17,3 por ciento) y a los de experiencia previa (25 por ciento). El 24 por ciento tenía cuatro o más años de rehabilitados y con mala autopercepción. Conclusiones: la edad inferior a 80 años, el sexo masculino, la rehabilitación con prótesis en ambas arcadas y las experiencias previas, son los factores que más se asocian con la buena autopercepción de salud bucal de los adultos mayores(AU)

Introduction: the increase of the number of older people leads to an increase in the number of people going to the dental services looking for rehabilitation, and in most of cases, they do not adapt themselves to the new conditions. Objective: to identify the association of some factors that influence in the self-perception of oral health over the older adults with removable acrylic partial denture. Methods: observational and descriptive research study conducted in 150 randomly selected old people aged over 60 years with denture. The evaluation variables were age, sex, type of denture, schooling, previous experience and length of wear, in association with self-perception of oral health measured by the geriatric oral health assessment index. Results: fifty three percent of patients were 60 to 69 years-old and this age group exhibited the most frequent regular self-perception (49.3 percent). Males (16 percent) were the ones with more frequency of responses that agreed with good self-perception. The highest frequency of bad self-perception was found in high school and university students who together accounted for 19 percent, in persons wearing upper denture (17.3 percent) and in those with previous experience of denture (25 percent). Twenty four percent of the group had been orally rehabilitated for 4 years or more with bad self-perception of oral health. Conclusions: less than 80 years of age, masculine sex, denture rehabilitation in both dental arches and previous experiences of wearing dentures are the factors that mostly relate to good self-perception of oral health in older adults(AU)

Self-report of gingival problems and periodontitis in indigenous and non-indigenous populations in Chiapas, Mexico.

OBJECTIVE: To estimate the prevalence of self-reported gingival and periodontal conditions and their association with smoking, oral hygiene, indigenous origin, diabetes and location (urban or rural) in indigenous and non-indigenous adults in Chiapas, Mexico. METHODS: A cross-sectional study of 1,749 persons, ≥20 years of age, living in four rural and four urban marginal localities in Comitán (Chiapas, México). The variables investigated were: age; sex; indigenous origin; oral hygiene; halitosis; chewing ability; gingival conditions; periodontitis; smoking; alcoholism; diabetes; and location. Bivariate analysis and a logistic regression model were used to identify the association of periodontitis with the independent variables. RESULTS: In total, 762 (43.6%) indigenous and 987 (56.4%) non-indigenous persons were interviewed. Their mean age was 41 ± 14 years, 66.7% were women and 43.8% lived in rural locations. Gingival problems were reported by 68.5% and periodontitis by 8.7%. In total, 17.9% had used dental services during the previous year, 28.7% wore a removable partial or a complete dental prosthesis, 63.7% had lost at least one tooth, the prevalence of diabetes was 9.2% and the prevalence of smoking was 12.2%. The logistic regression model showed that age, diabetes and the interaction between rural location and indigenous origin were associated with the presence of periodontitis. CONCLUSIONS: Indigenous people living in rural areas are more likely to have periodontitis. It is necessary to promote oral health practices in indigenous and marginalised populations with a focus on community-oriented primary care.

Sociodemographic determinants of usage of removable partial denture in a tertiary hospital: A retrospective study.

Objective: To determine the influence of sociodemographic characteristics on pattern of removable partial denture use in a tertiary institution over a one-year period. Methods: This was a retrospective study using records of partially dentate patients seeking replacement for their missing teeth within one-year duration. Information retrieved from the patients' records included demographic characteristics such as gender, age, marital status, occupation, arch type, number and reasons for missing teeth and type of removable partial denture. Statistical analysis was performed using statistical package for social science (SPSS) version 17 (Chicago, IL.). The analysis was done using frequency distribution, cross tabulations, t test and test of significance with chi square. P<0.05 was considered statistically significant. Results: A total of 98 patients were seen over the study period with a male/female ratio of 1:1.45. The patients' age ranged from 20 to 89 years with a mean age of 47.19 ± 18.37. The number of teeth replaced ranged from 1 to 17 with a mean of 3.13 ± 3.30 teeth. The mean number of missing teeth was significantly higher among patients aged 50 years and above (p = 0.002). Majority (69.4%) of the patients were married and 59.2% were working class (skilled and unskilled). The Kennedy's Class III saddle was the most prevalent in the maxilla while Class IV was most prevalent in the mandible; a difference that was statistically significant. Conclusion: Socioeconomic status, age and gender influenced the use of removable partial denture.

Three-Year Analysis of Fixed and Removable Telescopic Attachment-Retained Implant-Supported Dental Prostheses: Survival and Need for Maintenance.

PURPOSE: The purpose of this retrospective clinical study was to evaluate the clinical outcomes of fixed implant-supported dental prostheses (FISDPs) and removable ISDPs (RISDPs) retained by telescopic attachments, the factors influencing survival, and the type and number of maintenance treatments required during the observation period. MATERIALS AND METHODS: This retrospective clinical study is based on patients who were provided with ISDPs between 2004 and 2010. Patient sex, type of prosthesis, location, opposing dentition, and the effect of continuous follow-up on the probability of a favorable outcome, as well as the number of maintenance treatments, were analyzed. A statistical analysis was performed using the Kaplan-Meier method. RESULTS: A sample of 233 patients with 157 FISDPs and 76 RISDPs supported by a total of 567 implants was randomized and included in the analysis. The mean observation period was 15.9 ± 15.4 months (maximum, 66.0 months). During the observation period, 3.9% of prostheses (7/157 FISDPs and 2/76 RISDPs) ceased to function and 2.3% of implants (13 implants) were lost. The mean survival time was 59.7 ± 2.3 months, with a survival probability of 90.2% after 3 years. Prostheses in the mandible showed significantly higher survival rates than those in the maxilla. Maintenance treatments had to be performed at an earlier stage for patients with RISDPs than for patients with FISDPs. In patients with a conventional removable prosthesis in the opposing arch, the time until maintenance was needed was significantly shorter. CONCLUSION: Within the limitations of a retrospective study, it can be concluded that the FISDPs and RISDPs show equally good survival rates after 3 years in function. RISDPs showed a greater and earlier need for maintenance treatments during the first years in function.

A field survey of the partially edentate elderly: Investigation of factors related to the usage rate of removable partial dentures.

Although the shortened dental arch (SDA) concept has been known to all over the world, acceptance of the SDA concept as an oral health standard can be questionable from the patients' point of view, even if it is biologically reasonable. Furthermore, because the health insurance system covers removable partial dentures (RPDs) for all citizens in Japan, SDA patients seem to prefer to receive prosthetic treatment to replace the missing teeth. However, there were few field surveys to investigate the usage rate of RPDs in Japan. The purpose of this study was to determine the usage rate of RPDs in older Japanese subjects and to investigate the factors related to the usage of RPDs. Partially edentate participants (n = 390) were included in this study. Oral examinations were conducted to record several indices. The Cochran-Armitage trend test was used to evaluate the relationship between the number of missing teeth and the usage rate of RPDs. Chi-squared tests and logistic regression analysis were conducted to evaluate the factors related to the usage rate of RPDs. Usage of RPDs had a significantly positive association with the number of missing distal extension teeth and bilaterally missing teeth. The usage rate of RPDs increased as the number of missing distal extension teeth increased (P for trend < 0·001). The conclusion of this study was that participants with missing distal extension teeth had higher usage rates of RPDs than other participants, and the usage rate increased as the number of missing distal extension teeth increased.

Survival of teeth treated with cast post and cores: A retrospective analysis over an observation period of up to 19.5 years.

STATEMENT OF PROBLEM: Scientific data about the long-term survival of teeth treated with cast post and cores are scarce. Retrospective studies often use different target events for their analyses. A comparison is therefore complicated. For associated tooth-, jaw-, and patient-related factors little evidence exists as to their effect on survival. PURPOSE: The purpose of this study was to extend the knowledge on the survival of teeth treated with cast post and cores for observation periods of more than 10 years. A decrease or increase in survival times according to the presence or absence of associated parameters needs to be evaluated. MATERIAL AND METHODS: A retrospective evaluation was conducted of all cast post and cores inserted in 1 university clinic between January 1992 and June 2011. A Kaplan-Meier survival analysis was carried out by using extraction as the target event. The survival curves for different tooth types, the presence or absence of adjacent teeth, and the prosthetic restoration of the respective jaws were compared by using the log-rank test (α=.05). A Cox regression model was calculated for multivariate analyses. RESULTS: A total of 717 cast post and cores for 343 patients were recorded. The mean survival time was 13.5 years. A statistically significant decrease in survival times was found for canines (11.9 years) and premolars (13.4 years) versus molars (14.1 years), no adjacent teeth (10.6 years) versus at least 1 adjacent tooth (13.8 years), and the restoration with removable dental prostheses (12.5 years) versus fixed dental prostheses and single crowns (13.9 years). The largest reduction in survival time was found for teeth being used as an abutment for a double crown-retained removable partial dental prosthesis (telescopic denture) (9.8 years). Tooth type and adjacent tooth status remained as significant variables within the multivariate Cox regression model. CONCLUSIONS: Cast post and cores have an acceptable long-term survival time. Because different factors may influence survival, considering these factors in treatment planning may increase the long-term success of these restorations.

Treatment needs and skill mix workforce requirements for prosthodontic care: a comparison of estimates using normative and sociodental approaches.

BACKGROUND: The traditional measure for assessing dental treatment needs and workforce requirements based solely on normative need (NN) has major shortcomings. The sociodental approach (SDA) to assess needs overcomes some of the shortcomings as it combines normative and subjective needs assessments and also incorporates behavioural propensity (Sheiham and Tsakos 2007). The objective of this study was to estimate and compare prosthodontic treatment needs and workforce requirements, using the normative and the sociodental approaches for different skill mix models. METHODS: A cross-sectional study was conducted on 732 university employees aged 30-54 years. Normative prosthodontic need was assessed using the WHO (1997) method. The SDA includes NN and also considers oral impacts, measured through the OIDP index, and behavioural propensity. Estimates of prosthodontic need and dental workforce requirements using the two methods were compared using McNemar and Wilcoxon Signed Rank test respectively. The dental workforce required for prosthodontic treatment based on NN and SDA approaches were then compared using different workforce skill mix models. RESULTS: The proportion of subjects needing prosthodontic treatment was lower by more than 90% when the SDA was used compared to NN. The number of dentists required for prosthodontic treatment per 100,000 people were 98.8 using NN compared to 2.49 using SDA. Using a skill mix approach, the requirements for dentists per 100,000 people decreased slightly when more denture procedures were delegated to dental therapists. CONCLUSION: There were very much lower levels of prosthodontic treatment needs and workforce requirements when using the sociodental approach compared to normative methods.

Dental status and self-assessed chewing ability in 70- and 80-year-old subjects in Sweden.

The objective was to compare two cohorts of elderly people, 70 and 80 years old, with respect to dental status and self-assessed chewing ability. The hypotheses were as follows: (i) dental status is associated with self-assessed chewing ability; (ii) chewing ability is poorer among the 80- than the 70-year-old subjects. Identical questionnaires were in 2012 sent to all subjects born in 1942 and 1932, living in two Swedish counties. The response rate was 70.1% resulting in samples of 5697 70- and 2922 80-year-old subjects. Answers to questions on self-assessed chewing ability, dental status and some other factors have been analysed. Dental status varied but was in general good; 72% of the 70- and 60% of the 80-year-old subjects reported that they had all or only few missing teeth. Rate of edentulism was 3% and 7%, respectively. Removable partial dentures were reported by 6% and 10%, respectively, implant treatment by 13% in both cohorts. Self-assessed chewing ability was mostly good and correlated with the number of teeth (Spearman rho = 0.46). A majority of the edentulous subjects assessed their chewing ability as very or fairly good. Logistic regression showed that self-assessed chewing ability was significantly associated with a number of dental variables but also with general health. In conclusion, dental status was relatively good at both ages but somewhat poorer in the older cohort. Dental status, some other dental variables and being healthy were in both age groups significantly associated with self-assessed chewing ability.

Provision of specific dental procedures by general dentists in the National Dental Practice-Based Research Network: questionnaire findings.

BACKGROUND: Objectives were to: (1) determine whether and how often general dentists (GDs) provide specific dental procedures; and (2) test the hypothesis that provision is associated with key dentist, practice, and patient characteristics. METHODS: GDs (n = 2,367) in the United States National Dental Practice-Based Research Network completed an Enrollment Questionnaire that included: (1) dentist; (2) practice; and (3) patient characteristics, and how commonly they provide each of 10 dental procedures. We determined how commonly procedures were provided and tested the hypothesis that provision was substantively related to the three sets of characteristics. RESULTS: Two procedure categories were classified as "uncommon" (orthodontics, periodontal surgery), three were "common" (molar endodontics; implants; non-surgical periodontics), and five were "very common" (restorative; esthetic procedures; extractions; removable prosthetics; non-molar endodontics). Dentist, practice, and patient characteristics were substantively related to procedure provision; several characteristics seemed to have pervasive effects, such as dentist gender, training after dental school, full-time/part-time status, private practice vs. institutional practice, presence of a specialist in the same practice, and insurance status of patients. CONCLUSIONS: As a group, GDs provide a comprehensive range of procedures. However, provision by individual dentists is substantively related to certain dentist, practice, and patient characteristics. A large number and broad range of factors seem to influence which procedures GDs provide. This may have implications for how GDs respond to the ever-changing landscape of dental care utilization, patient population demography, scope of practice, delivery models and GDs' evolving role in primary care.

Partially Edentulous Arches: A 5-Year Survey of Patients Treated at the Fluminense Federal University Removable Prosthodontics Clinics in Brazil.

PURPOSE: This study investigated the number and Kennedy Classification of the edentulous arches in patients treated at the Removable Partial Denture (RPD) Clinics of the Fluminense Federal University School of Dentistry (FO-UFF) in Rio de Janeiro, Brazil, from 2005 to 2010. MATERIALS AND METHODS: A cross-sectional retrospective survey was conducted on patient record charts to identify gender, age, number, and location of the edentulous arches, and Kennedy Class type. RESULTS: One hundred and forty-six patients were analyzed for this study (96 [65.8%] women and 50 [34.2%] men). Two hundred and ninety-two arches were analyzed: 74 arches (25%) were found with intact dentitions, 18 (6.1%) were edentulous arches, and 200 (68.8%) were partially edentulous arches. Ninety-one patients (62.3%) needed oral rehabilitation with RPDs on one arch and 55 (37.7%) in both arches. One hundred and eight (53.2%) partially edentulous mandibles and 92 (46.8%) partially edentulous maxillae were found. Kennedy Class I was more frequent in the mandibular arch (58 patients; 29%) whereas Kennedy Class III was more frequent in the maxillary arch (40 patients; 20%). Patients aged between 51 and 60 years presented the highest percentage of partially edentulous arches (33.6%). CONCLUSION: Mandibular Kennedy Class I and maxillary Kennedy Class III presented the highest frequency in patients treated at the FO-UFF. These results are in agreement with previous studies that evaluated the different Kennedy classes in partially edentulous arches.

Implant Tooth-Supported Removable Partial Denture with at Least 15-Year Long-Term Follow-Up.

PURPOSE: The aim of the present report is to describe the long-term follow-up of cases treated with implant tooth-supported removable partial denture (ITSRPD) after at least 15 years. MATERIALS AND METHODS: The study sample comprised 20 consecutively partially edentulous patients treated with ITSRPD. Implants were placed in order to improve unfavorable removable partial denture design resulting from unfavorable teeth distribution and biomechanical considerations, esthetic, or periodontal challenges. All patients were followed up every 6 months for the first 2 years and annually thereafter for at least 15 years. Recall visits for professional cleaning and oral hygiene re-enforcement were scheduled every 3 to 6 mounts. RESULTS: A total of 42 implants were placed in 20 patients and restored with ITSRPD. All implants and prosthetic devices functioned successfully throughout the 15 years of follow-up. Three patients had gone through further implant placement several years after ITSRPD was provided, and a fixed implant-supported restoration was provided on the original and new implants. No implant failure was noted during follow-up, resulting in a rate for implant survival of 100% for the study. Marginal bone loss around implants ranged between 0 and 2 mm (mean 0.64 ± 0.6 mm). During the follow-up period, prosthetic complications were minor and included one rest rupture. All patients answered a questionnaire and were satisfied with the prosthesis. They reported good chewing ability and stability of the prosthetic devices. CONCLUSIONS: ITSRPD can be used with predictable long-term results in carefully selected and well-maintained population. Patients should be advised of their role in maintenance, and a comprehensive recall system is mandatory to obtain satisfactory long-term results.

Partial Edentulism based on Kennedy's classifcation: an epidemiological study.

BACKGROUND: The aim of this study was to determine the incidence of different Kennedy's classes of partial edentulism during 18 months period. MATERIALS AND METHODS: Patients were clinically examined for various Kennedy's classes of partial edentulism in the outpatient department (OPD), prosthodontics, GPRDCH, Kurnool (Andhra Pradesh). RESULTS: Of the total 1,420 OPD patients, Kennedy's class III was the most frequent classification encountered (62%) and followed by Kennedy's class I (18%), class II (11%), and class IV (9%) in decreasing order. CONCLUSION: The patients with various Kennedy's classes of partial edentulism can be offered various treatment modalities like removable cast partial dentures, fixed partial dentures, over dentures and implant supported dentures. This study can be crucial for screening the population for incidence of tooth loss as a factor of gender and age. Clinical significance: Tooth loss appears to have an important role in the loss of esthetics and mastication. Study of incidence of various classes of partial edentulism provides clinically useful information for dental training and continuing education.

Partial edentulism and unmet prosthetic needs amongst young adult Nigeria.

INTRODUCTION: Treatment options for missing tooth/teeth which are mostly commonly caused dental caries, periodontitis and trauma include partial dentures, bridge and implant. In developing countries, missing tooth/teeth replacement constitutes a high unmet dental need. The objective of the study was to determine the prevalence of partial edentulism and prosthetic unmet dental needs among young adults in Nigeria. MATERIALS AND METHODS: A total of 244 medical students of college of medicine were recruited and studied using interviewer administered questionnaire which elicited information on sociodemographic, tooth loss and replacement. Data was analyzed with SPSS version 16.0 statistical software for windows. RESULTS: There were 98 males (40.2%) and 146 females (59.8%). A total of 35 participants out of the 244 studied participants had missing tooth/teeth giving a prevalence of 14.3%. The major reason of tooth loss was caries (48.6%). The upper left (16.7%) and right (16.7%) had the highest tooth mortality. Of the 35 participants with missing teeth, 4 (11.4%) of had replacement while 31 (88.6%) did not have any form of replacement. The teeth replaced were upper right, left anterior (75%) and upper right posterior (25%). Reasons for non-replacement were not being bothered--14 (45.2%), ignorance of replacement therapy-- 7 (22.6%), misinformation--1 (3.2%) and lack of money--2 (6.5%). Those that replaced 4/42 (9.5%) did so with removable partial dentures (100%). The majority that replaced were females 3/4 (75%). Half (50%) of those that replaced were satisfied and the reasons for non-satisfaction were pain from denture and unnatural feel of denture. CONCLUSION: Data from this study revealed low prevalence of tooth loss with high unmet tooth replacement needs among the participants. Tooth/teeth replacement options should be incorporated in postoperative instructions after extraction and dental awareness should be improved among medical students.

Dental technology services and industry trends in New Zealand from 2010 to 2012.

OBJECTIVE: To provide a snapshot of the New Zealand dental technology industry and influencing factors. BACKGROUND: Developing an understanding of the commercial dental laboratory environment in New Zealand can provide insight into the entire dental industry. METHODS: A web-based survey was the primary method for data collection, with separate questionnaires used for dental laboratory owners and dental technician employees. RESULTS: The mean net income for dental laboratory owners in New Zealand was similar to that of the United Kingdom, at $40.50 per hour. Clinical dental technicians are the highest paid employees, with a mean of $33.49 per hour. The mean technical charge for complete dentures was $632.59; including clinical services, it was $1907.00. The mean charge for a porcelain-fused-to-metal (PFM) crown was $290.27. Dental laboratory owners expressed fear about the possibility of losing dental clients to overseas laboratories due to the availability and cheap charge of offshore work. Only 25.4% of dental laboratories surveyed had computer-aided design (CAD) facilities, and even fewer (7.9%) had computer-aided manufacturing (CAM) systems. CONCLUSION: Clinical dental technology appears to be prospering. The dental technology industry appears to be adapting and remains viable, despite facing many challenges.

Does dental disease presence equate to treatment need among care home residents?

OBJECTIVES: This study aimed to explore the relationship between dental disease, complexity and dental treatment needs of care home residents. METHODS: Survey of residents in care homes in Wales. Random sample of participants from a random selection of care homes across Wales, UK. Data collection involved questionnaires and dental examinations. RESULTS: Data were collected from 655 care home residents in 213 care homes. Half of all residents reported good or very good oral health but most had dental treatment needs. 73% of dentate residents had active caries, of those, 53% required restorations and 37% needed extractions. All were deemed to require dental examination. 60% of dentate residents and 50% of edentate residents had case complexity, which influenced the delivery of care. CONCLUSIONS: There is significant unmet dental treatment need amongst care home residents. Dental disease presence alone is a poor indicator of the need for care and does not account for case complexity or the shift towards a patient centred rather than disease focussed approach to care. Measures for treatment needs and complexity are required when undertaking assessments of oral health needs in care homes. CLINICAL SIGNIFICANCE: Traditional oral health surveys measuring dental disease do not necessarily equate to treatments required for care home residents and do not reflect the complexity and difficulties involved in delivering dental care. This survey highlights dental needs in care homes, and the difficulties involved in delivering care to address these needs.
