Background and Objective: Gingival biotype can be assessed using a variety of invasive and non-invasive procedures, such as direct probing, transgingival probing, ultrasound-guided approaches, and, for the more sophisticated, cone-beam computed tomography. The aim of this study was to evaluate gingival biotype in relation to transgingival probing and cone-beam computed tomography (CBCT). Materials and Methods: This study included a total of two hundred healthy individuals. Gingival thickness was assessed and measured from the right and left maxillary central incisor teeth using CBCT and transgingival probing of the attached gingiva. The measurements were analyzed with regard to tooth type (central incisor). Linear measurements for gingival biotype were measured using both methods. Correlations and differences between measurement methods were assessed. Results: The mean age of study participants was 32.49 ± 8.61 years. The radiographic measurements on CBCT were 1.34 ± 0.17 mm for the...

The aim of the present study was to evaluate the fracture loads of polymethyl methacrylate (PMMA) complete denture bases reinforced with glass-fiber mesh and orthopedic casting tape (OCT) in comparison to conventional PMMA dentures under artificial aging. Dental fiberglass framework (Group 1) and OCT (Group 2 and 3) reinforced PMMA acrylic dentures were fabricated on the edentulous ridge. Ten PMMA dentures without reinforcement (Group 4) were included as controls. All specimens were placed in a chewing simulator chamber, and fatigue load was applied. To assess the fracture loads, static loads with a universal testing machine were applied. Fractured specimens in each group were evaluated under a scanning electron microscope. The data were statistically analyzed employing analysis of variance and Tukey post-hoc test. The association of denture weight and thickness on fracture load was assessed using Pearson and Spearman correlations. Dental fiberglass (Group 1) displayed the highest f...

This in vitro study aimed to compare the fracture resistance between pressed custom-made polyetheretherketone (PEEK) post and core and fibre reinforced post and composite core. A total of 40 single rooted extracted teeth were selected, endodontically treated, and prepared to receive the posts. Specimens were randomly divided into two main groups (n=20/group): group 1, (PEEK); group 2, fibre post. PEEK post was manufactured with a computer-aided design/computer-aided manufacturing system further divided into four sub groups (P7, P12, F7, F12) based on lengths 7 and 12 mm at which the posts were cemented. All posts were cemented with self-adhesive resin cement, and specimens were stored in 0.1% thymol solution during the experiment at all the times except during preparation and testing. A universal testing machine was used to measure the fracture resistance. The fracture resistance values (mean and SD, in newtons) were 1255N (P7), 1562N (P12), 1065N (F7), and 1384N (F12). Only P12 exh...

Background The goal of the current in vitro study was to assess the dimensional accuracy of dental impressions when stored at different times, temperature and humidity. Methods Impressions were poured to an aluminium triangular die and three teeth placed at the three corners of the die. A total of 130 impressions were made, in which 10 were poured immediately following manufacturers' instructions and the remaining 120 specimens were divided into two groups on the basis of relative humidity during storage. Group-1: 100%, Group-2: 50% relative humidity. Impression was poured with type IV gypsum. The below points were chosen to determine the length between in each of the specimens using the traveling microscope with 10x magnifications after 24 hours of model recovery for calculating the effect of changes in storage conditions- relative humidity, temperature and delay in pouring the impressions, on dimensional accuracy. Results Analysis of the results revealed that the casts achieved by pouring alginate impressions without delay were most accurate than the delay pouring. With the increase in temperature and time, the distance between the points increased and the casts obtained were bigger. Conclusion Irreversible hydrocolloids should be poured immediately for optimum dimensional stability.

The oral health-related quality of life determines the quantity to which oral health disrupts the regular life and common functioning of an individual. To evaluate the oral health problems of older adults, Geriatric Oral Health Assessment Index (GOHAI) can be used. GOHAI was developed by Atchinson and Dolan3 before and after complete denture therapy”. Study Design: Cross sectional study. Setting: Department of Prosthodontics, Lahore Medical and Dental College, Lahore. Period: February 18, 2018 to August 17, 2018. Material & Methods: Patients will be selected for the study according to the criteria. Patient history and clinical examination was undertaken. Upper and lower complete dentures was made-up for 30 patients (both male and female) using standardized clinical and laboratory methods. Conventional procedures were applied to complete denture construction. Complete dentures were constructed in the similar dental laboratory within the institution by compression moulding method. Lab...

Objectives: The aim of this study was to assess the knowledge and infection control practices among private dental laboratories in Karachi. Study Design: Cross sectional study. Setting: Private Dental Laboratories of Karachi. Period: 01st September 2017 to 01st February 2018. Materials and Methods: A pre structured questionnaire comprised of 09 questions regarding infection control was used to collect the data. A total 35 questionnaires were given to dental technicians. 29 questionnaires were obtained out of 35 distributed (response rate: 83%). Statistical Package for the Social Sciences (SPSS) version 17.0 was used for data analysis. Results: Gloves were not worn by 76% of respondents while receiving the clinical items. Protective eyeglasses and protective face shield were not worn by 38% and 13% of respondents respectively during laboratory work. Few 13% of respondents were vaccinated against the hepatitis b virus. Clinical items were disinfected by 17% of respondents if not disin...
