Pattern of oral hygiene maintenance among patients seen at two tertiary hospitals

The study was conducted in two tertiary hospitals to observe frequency and duration of tooth brushing and their relation with incidence of caries, gingivitis and sensitivity. In this study total 1200 patients were selected randomly reported to Department of Operative Dentistry of both institutes. The duration of study was one year. Out of these 1200 patients 755 [62.91%] were male and 445 [37.08%] were female with age range from 15- 74 years. All patients were divided into three groups on the basis of their age, in group 1 age range was 15-25 years, in group 2 age range was 26-50 years while group 3 included patients of above 50 years. After taking consent from the patients a self designed questionnaire was used to get necessary details. Data compiling and statistical analysis was done by using SPSS - 20 and results were obtained. Brushing frequency and duration of brushing is better in group 2 followed by group 1 and 3 respectively. The rate of caries and gingivitis is also significantly higher in group 2 [50.8% and 40.4%] followed by group 1 [21.6% and 15%] and group 3 [1.8% and 2.5%] respectively

Quality of life in pediatric patients after providing removable acrylic partial denture

The study was conducted to observe quality of life in pediatric patients provided with acrylic removable partial denture visiting Hamdard University Dental Hospital, Karachi. It was a descriptive type of study. The study was carried out in the Department of Prosthodontics, Hamdard University Dental Hospital, Karachi from January 2012 to December 2013. Non probability purposive sampling technique was used. Total 30 patients visited to Prosthodontics Department of Hamdard University Dental Hospital, Karachi for provision of prosthesis were included in this study. Age range varied from 03-14 years, while sixteen were boys and fourteen were girls. Four of them were already denture wearer. Questionnaire based on OHIP-14 was used to evaluate quality of life in these patients. After collection of data, results were tabulated on SPSS. All patients were provided with acrylic removable partial dentures. Regular follow up was maintained and all patients were satisfied with the performance of their prosthesis. Acrylic removable prosthesis can be very effective for oral rehabilitation of pediatric patients when fixed prosthesis is not feasible due to multiple factors

In vitro comparison of the apical microleakage of mineral trioxide aggregate [MTA] with amalgam as a retrograde filling material

The objective of this study was to compare apical microleakage of MTA with Amalgam following retrograde root filling. Experimental study. This study was conducted at the Department of Operative Dentistry, Fatima Jinnah Dental College and Hospital, Karachi March 2006-March 2007. One hundred twenty extracted human single rooted teeth were randomly assigned into four groups of 30 teeth each. The root canal filling carried out and retropreparations were cut in each root using round bur to a depth of 2-3 mm. Cavity varnish applied prior to retrofillings. Group I retrofilled with amalgam. In group II MTA was used, Group III served as negative control and group IV as a positive control. Roots were suspended in 2% methylene blue and placed into incubator at 37°C for 7 days. Teeth were split and chosen halve evaluated using a dissecting microscope at 10[x] magnification. The roots were evaluated and scored as either acceptable or unacceptable. The results showed that MTA displayed significantly less dye leakage than Amalgam. 24 samples [83%] out of 29 samples of MTA scored as acceptable, where as 4 specimens [16%] out of 28 samples of Amalgam showed acceptable score. MTA was found to be superior to Amalgam in providing apical seal when used as a root-end filling material. Favorable results were obtained with MTA in leakage study and it was concluded that MTA provided a better apical seal than Amalgam

Root canal treatment; Frequency in department of endodontic in dental colleges of Karachi

To determine the frequency of root canal treatment in endodontic department of dental colleges of Karachi. Cross-sectional study. Department of endodontics, Sir Syed Dental College and Hospital, Karachi from 1st May 2011 to 31st August 2011. Of the 400 teeth from 370 individuals [age range 12-50 years] were endodontically treated during four months by faculty members and postgraduate residents enrolled in a specialisation programme in department of Endodontics. All patients were examined clinically and radiographically. For each case, information was collected in specifically designed proforma including location of the affected tooth, age and gender and reasons for endodontic treatment. Of the 400 treated teeth, 225 [56.25%] were mandibular and 175 [43.75%] were maxillary teeth. 236 teeth [59.0%] were from females and 164 [41.0%] from males. Significant differences were found between the maxillary and mandibular arch. Molars and premolars required significantly more frequent endodontic treatment than canines and incisors as revealed in fig.1. The most frequently treated tooth was the mandibular right first molar [9.12%] followed by the mandibular left first molar [7.07%]. The mandibular first molar was the most common tooth to undergo endodontic procedure than maxillary first molar. The most frequently diagnosed pathosis was irreversible pulpitis [44%], pulp necrosis [22%], retreatment endodontic [17%], elective RCTs [10%] traumatic exposures were [7%] as shown in fig. II. Irreversible pulpitis was the most frequent cause of root canal treatment followed by pulp necrosis. Teeth of females required more endodontic treatment than males. The most frequent root canals were carried out in mandibular molars than maxillary molars
