ABSTRACT
Objective: the objective of the study was to compare the frequency and amount of root resorption after 6 months of fixed orthodontic treatment in crowding and non-crowding orthodontic patients
Methods: this cross sectional study conducted at the Department of Orthodontics, Alvi Dental Hospital, Karachi. The six month study was conducted from June - December 2008. Sample consists of 60 patients of two groups. Group A comprises of 30 patients of crowding in maxillary anterior teeth and Group B consisted of 30 patients of non crowding cases of maxillary anterior teeth. The data was collected through non probability purposive sampling. In preorthodontic phase [stage I], the apical root resorption was measured as a difference between length of tooth at pretreatment [T1] as compare to stage II [Postorthodontic stage] i.e. length of root six months after the orthodontic treatment [T2]. Subjective scoring of resorption was done from 0-4 with the help of apical root resorption index. Finally the root resorption was compared in between two groups i.e. crowding and non-crowding and data was recorded in a predesigned questionnaire
Results: in crowding group we found 27 [90%] cases with apical root resorption of less than 2mm as compared to non-crowding group, which had 21 [70%] cases. When compared the length of the tooth in stage II the average length was significantly higher in non-crowding group as compared to crowding [p<0.05]. In crowding group we found statistically significant difference in mean decrease length of tooth [mm] at T2 i.e after 6 months compared to mean tooth length [mm] [p<0.05] at T1. We estimated mean decrease of difference in length of T1 and T2 in crowding group compared with noncrowding group [p< 0.05]
Conclusion: there is significant difference [p<0.05] in mean length of tooth root in crowding and noncrowding patients after six months of orthodontic treatment

ABSTRACT
Objective: The aim of this study was to evaluate the clinical and anatomical application of buccal fat pad as an interpositional material in the surgical treatment of oral submucous fibrosis [OSMF] for improvement of mouth opening and its movements
Methods: OSMF has become a chronic, distressing condition of uncertain aetiology in Pakistan which rapidly involves the oral structures along with other parts of upper gastrointestinal tract
The study was conducted in Department of Oral and Maxillofacial Surgery, Ziauddin College of Dentistry, Ziauddin University, Karachi, from December 2013 till July 2015. We evaluated 50 diagnosed OSMF patients, with history of chewing areca/betal nut or other similar products, with burning sensation on having spicy ingredient, trismus 4-25mm with palpable fibrous bands on the buccal mucosa intraorally with rigidity and blanching were included in the study. Good clinical improvement with minimal morbidity by the use of buccal fat pad was noticed in patients with severe limited mouth opening along with regular and vigorous physiotherapy
Results: In 50 patients, the range of preoperative mouth opening was 4-24mm [14 +/- 4.90], the intra operative mouth opening was 25-38mm [33.25 +/- 4.17]. The patients were discharged after 72 hours at this time mouth opening was 25-36mm [0.63 +/- 3.82]
Comparison of pre-operative with intra and post-operative mouth opening was statistically significant
Conclusion: This study has shown that use of interpositioning buccal fat pad flap improves the mouth opening and movement in OSMF patients

The mean for the year 2013 issues was 1 +/-6.18 for June issue and 13.3 +/-3.0 for December issue, respectively. The number of mistakes identified in the manuscripts in descending order included punctuation marks, use of inappropriate tense and voice, use of articles [a, an, the], use of prepositions, wordiness [excessive words], long sentences, spelling mistakes, flow of thought process, incomplete sentences, and frequent use of abbreviations
Conclusion: a large number of manuscripts revealed inappropriate use of punctuation marks followed by tenses, active and passive voices
ABSTRACT
Objective: The objective of this study was to assess the pattern of bacteraemia after non surgical extraction of teeth. Methods: This prospective descriptive study was conducted at an out-patient setting at Karachi Medical and Dental College, Dental Hospital Karachi, over a period of six months [January 2007 to June 2007] on fifty patients. A pre designed performa was used to collect the relevant information from the patients. All cases of bacteremia [diagnosed on culture media] after non-surgical extraction of tooth/ teeth were included in the study. Total seven culture samples were taken from each patient pre and post extraction. Results: Thirty-four [68%] patients were male and sixteen [32%] were female. Mean age of patients was 32.14 +/- 11 years. The commonest reason for tooth extraction was dental caries. The preextraction intravenous blood culture was negative in all fifty patients. The post extraction intravenous culture after one minute was negative in 60% of patients, after five minutes it was negative in 18% of patients. After fifteen minutes post extraction, 99% of blood cultures were positive for bacterial growth, while 56% of blood cultures were negative for any bacterial growth after thirty minutes. Peptostreptococci and Streptococcus viridians species were the commonest bacterial isolates. Conclusion: Highest level of bacteraemia occurred after fifteen minutes of non-surgical tooth extraction. Peptostreptococci and Streptococcus species were found to be the commonest isolates
ABSTRACT
Odontogenic infections lead to life-threatening complications once they reach potential fascial spaces due to decreased immunity in pregnancy. It may also occur due to patient negligence, delayed diagnosis and mismanagemnet. Infratemporal space infection is a rare but a serious sequel of odontogenic infection. We report the case of a 20 year old, four months pregnant patient with carious left maxillary first molar with fascial space infection. Following extraction of this tooth and despite appropriate antibiotics the patient developed infection in the infratemporal and masticator space, followed by a orbital abscess
ABSTRACT
Objectives: To determine the most effective method of sterilization and disinfection of extracted human teeth foruse in dentalcolleges
Study Design: Case Control study
Place and Duration of Study: This study was conducted at OMFS and Microbiology Department, KMDC, Karachi from June 2013 to December 2013
Materials and Methods: Freshly extracted human teeth [n=50] were obtained and sent for bacteriological processing. Teeth were dividing into 5 groups; samples were taken pre and post treatment. A platinum wire loop was flamed in red heat and cooled; sample was inoculatedinC for 48 hours. Colony count was noted to observe the quantity of microorganism, which determines the efficacy of the sterilizing method

ABSTRACT
Careless high speed driving and increasing violent attacks in the Karachi had increased the burden of maxillofacial trauma proportionally. The objectives of the study were to: Enlist the various causes of Mandibular fractures in patients coming to the Department of Oral and Maxillofacial Surgery, Abbasi Shaheed Hospital and to describe the various sites of Mandibular fracture. The descriptive, cross sectional study on the patients fulfilling the inclusion criteria. They were asked for the parameters which includes age, gender, etiology of fracture, and site of fracture using a questionnaire. Statistical analysis of continuous and categorical variables was conducted using SPSS version 16.00. Male preponderance with male: female ratio of 2.4: 1, 71.1% males and 28.9% females, mean age of the patient was 28.2 years 12.7. The most common cause of injury was recorded as Road traffic accident [RTA] 65.6% and the most common site of fracture was Parasymphysis [24.1%]. This study clearly demonstrates the most common cause of Mandibular fractures was RTA and the most common site was the Parasymphysis in our population
ABSTRACT
Background: Adenomatoid odontogenic tumor [AOT] is relatively an uncommon oral tumour, which accounts for about 3-7% of all odontogenic tumors as reported in the literature, but local reporting in Pakistan is insignificant. AOT is a benign [hamartomatous], noninvasive odontogenic tumour with slow and sustained growth. This report describes the surgical therapy, clinical course and morphological characteristics of an AOT, which developed in the maxilla of 22 years old female patient, initially diagnosed as a Gobulomaxillary Cyst, based on the clinical and radiological features. No local recurrence has been observed so far, as it was successfully completely removed under local anaesthesia
ABSTRACT
A case of twenty years old female is reported, which was treated inappropriately. She complained of a painless lump located on the right cheek at middle half of the face. An early diagnosis of sebaceous cyst was made. Excision was performed and histopathological findings revealed Pilomatrixoma. Pilomatrixoma is an uncommon, harmless, skin lesion derived from hair matrix cells. It is composed of an epithelial component of the most proximal portion of hair follicle. It is most often diagnosed in young children but may also affect adults. Single skincoloured or purplish lesions arise on the head and neck, but they may occur at any site. The key to diagnosis is identification of darkly stained 'basophilic cells' and 'shadow cells'. Calcium deposits are found in most of the lesions. Complete surgical excision is the treatment with rare chances of complications
