Abstract

Objectives

The aim of this study was to evaluate the bond strength of different direct reliners to acrylic resin for denture base.

Materials and methods

Double-cone specimens were made: HA-heat-cured acrylic resin-(n = 20); U-Ufi Gel Hard C-(n = 10); K: Kooliner-(n = 10); R-Rebase II Fast-(n = 10) and RH-Rebase II Fast + Resin Hardener-(n = 10). Ten HA samples were immediately submitted to cohesive test. The remaining HA samples and others were submitted to thermal aging (HAaged, 1000 cycles, 5.55oC), followed by tensile test. For tensile strength, 50 single cone-shaped samples were made of heat-cured acrylic resin and aged (HAaged, 1000 cycles, 5.55oC). After surface treatment, relining resin cones were build up using silicon molds, and stressed to failure. Values of cohesive and tensile strength were submitted to one-way ANOVA and Tukey's test (α = 5%).

Results

Bond strength were: HA/HAaged: 21.17 (±4.89)a, U/HAaged: 11.56 (±1.98)b, R/HAaged: 9.69 (±2.37)b, RH/ HAaged: 9.38 (±1.78)bc and K/HAaged: 5.98 (±1.90)c. The cohesive strength were: KCoe: 22.29(±4.06)a; RCoe: 23.99 (±3.29)a; RHCoe: 24.84 (±3.88)a; UCoe: 25.62 (±3.03)a; HAaged: 36.06 (±8.65)b and HA:42.29 (±7.68)b. Groups followed by the same letters do not show differences.

Conclusion

Bond strength of acrylic resin to acrylic denture base material is higher than the reliners and Ufi Gel Hard C showed the higher bond strength.

Abstract

Background

Areca nut chewing in different forms is getting more prevalent among the south Asian inhabitants. Its uses are progressing from adults to adolescents and especially its frequent use among the school going children. The aim of this study was to analyze the prevalence of areca nut chewing and its effect on the oral health of school going children.

Materials and methods

A cross-sectional study using a close ended questionnaire was conducted to collect the data from the school going children of Gadap town, Malir, Karachi. A random sample of 285 students (n = 285) were examined. The research instrument was self-structured close ended questionnaire. The questionnaire contained questions regarding the knowledge and consequences of chewing areca nut, its products and its effect on their oral health. The questionnaires were administered to the students in their respective classes and the filled questionnaires were collected on the same day. Chi-square test was used for differences in frequencies among the types of areca nut, practices of using areca nut and gender variables. Stata 11 was used for data analysis. Total number of 285 children were surveyed.

Results

There were 75.09% boys and 24.91% girls, mean age of the students was 6.23 (1.05). The range of the students was 4 to 8 years. The frequency of using areca nut and products containing areca nut in our study was 77.9%. There were 60.35% students both male and female who were identified to gutkha chewing habit. Frequency of consumption of chewing areca nut made products increases as the age's increases. The 74.38% respondents were suffering from oral lesions.

Conclusion

Chewing of areca nut and products containing areca nut is prevailing in rural areas especially among the lower age group of school going children. Both genders are equally and frequently use areca nut as habit.

Abstract

Background

Early childhood caries (ECC) is a common disease affecting very young children in today's era. The prevention of ECC depends upon the vital information parents are available with during the upbringing of the child.

Aim

This survey was undertaken to evaluate the awareness among parents about preventive aspects of ECC in Abha City, Kingdom of Saudi Arabia.

Methodology

A questionnaire study was conducted among young parents about preventive aspects of ECC in Abha City, Kingdom of Saudi Arabia. Descriptive statistics was used to observe the awareness.

Results

A total of 157 parents participated in the study of which 126 were mothers and 31 fathers. The mean age of the parents participating in the study was 34 years, and 55% of the participants had education till the university level. About half (53%) of the parents were unaware that the child should be taken for the first dental visit by 1 year of age. Around 60% of the participants had taken their children to the dentist only when the dental problem was in persistence and 48% of the participants allowed their child to sleep with milk bottle or juice in their mouth.

Conclusion

Hence, it can be concluded that the parents in Abha, KSA, are moderately aware of dental needs of their young children.

A Retrospective Panoramic Radiographic Study on Prevalence of Pulp Stones in South Karnataka Population

[Year:2016] [Month:January-March] [Volume:7] [Number:1] [Pages:4] [Pages No:14 - 17]

   DOI: 10.5005/jp-journals-10015-1356  |  Open Access |  How to cite  | 

Abstract

Background

Pulp stones are calcification in the dental pulp which can be present either in deciduous or permanent teeth. Exact causes of pulp stones are not known and several elements have been associated. It can be seen in healthy, diseased or as a part of various syndromes. Frequency of pulp stones fluctuated from 8 to 95% depending on the population studied. Our study is an attempt to know the prevalence of pulp stones in radiographs of South Karnataka population and to assess probable relations between pulp stones and gender, type of tooth, dental arch and quadrant. Comparison of our results with published documents was done and our study statistics can be considered as an added information in the field of forensic dentistry.

Materials and methods

One thousand panoramic radiographs were retrospectively evaluated which included 576 females 424 males aged between 18 and 70 years. A total of 27,184 teeth were examined for the presence of pulp stones. Associations of pulp stones with sex, tooth type, dental arch and side were noted.

Results

Pulp stones prevalence was 7.5% of subjects. Out of 27,184 teeth examined, 394 teeth revealed pulp stones (1.45%). Occurrences were rare in premolars (2%) but significantly higher in molars (54.6%). Pulp stones were seen more in first molars than second molars and in maxillary first molars than in mandibular first molars. Pulp stones were commonly seen in 26 to 45 years age group.

Conclusion

Pulp stones may provide useful forensic information when examining dental records to identify deceased persons. Dental features vary among different population and thus knowing the prevalence is significant in the forensic aspect.

Influence of Orthodontic Treatment on Smile Attractiveness as perceived by Common People, General Dentists and Orthodontists

[Year:2016] [Month:January-March] [Volume:7] [Number:1] [Pages:5] [Pages No:18 - 22]

   DOI: 10.5005/jp-journals-10015-1357  |  Open Access |  How to cite  | 

Abstract

Objectives

To analyze the influence of orthodontic treatment on smile attractiveness as perceived by common people, general dentists and orthodontists.

Materials and methods

The photographic records of 114 patients were screened and 72 patients who fulfilled the inclusion criteria were selected. The pretreatment and posttreatment smile photographs were rated on a 10-point scale by panels of common people, general dentists and orthodontists. Data were analyzed by one-way analysis of variance (ANOVA) with Tukey's post hoc test.

Results

The mean esthetic scores for pretreatment images as evaluated by the three panels; orthodontists, general dentists and common people were 3.26, 3.20 and 3.31 respectively. The difference in esthetic scores between these three groups was not statistically significant (p > 0.05). For post-treatment images, the mean esthetic scores by the three panels; orthodontists, general dentist and common people were 6.45, 6.50 and 7.32 respectively. Esthetic scores between these three groups differed significantly (p < 0.05) with common people displaying significantly higher score than orthodontists and general dentists, however no difference was seen between orthodontists and general dentists. It was also seen that the percentage change in mean esthetic scores from pre- to posttreatment smile was significantly higher for common people as compared to orthodontist (p < 0.05) and no difference was seen between orthodontists and general dentists or common people and general dentists respectively.

Conclusion

Though there is no difference in perception of smile esthetics between common people, general dentists and orthodontists, the influence of orthodontic treatment on smile attractiveness is appreciated differently by the common people as compared to general dentists and orthodontists.
