Effect of two triangular flap designs for removal of impacted third molar on maximal mouth opening

The aim of this study was to compare the effect of marginal flap and paramarginal flap designs on maximum mouth opening following surgical removal of impacted mandibular third molars. This comparative study consisted of sixty patients which were divided into two groups of thirty each and was carried out at Oral and Maxillofacial Department, Lahore Medical and Dental College, Lahore from June 2012 to October 2013. Maximum mouth opening was recorded preoperatively. A marginal flap was used in one randomly chosen half of the patient's sample, and a paramarginal flap was used in the other half. The effect of these flaps on maximum mouth opening was studied postoperatively. No significant difference was found between marginal and paramarginal flaps on maximum mouth opening at second and seventh days after surgical removal of impacted mandibular third molar [P>0.05]. Therefore, the decision to use a marginal flap or a paramarginal flap may be based on surgeon's preference

Outcome of management of mandibular third molar impaction by comparing two different flap designs

The aim of this study was to compare the outcome of management of mandibular third molar impaction in terms of wound healing and periodontal probing depth of the adjacent second molar in patients treated by marginal flap versus paramarginal flap. This quasi experimental study consisted of sixty patients divided into two groups of thirty each [ages 18 to 30 years], who required surgical removal of impacted mandibular third molars. Periodontal probing depth of the adjacent second molar was recorded preoperatively. A marginal flap was used in one randomly chosen half of the patient's sample, and a paramarginal flap was used in the other half. The influence of these flaps on wound healing and periodontal probing depth of the adjacent second molar was studied postoperatively. No wound dehiscence occurred with the use of marginal flap or the paramarginal flap at 1 and 2 weeks after surgery [P>0.05]. The buccal and distal probing depths of the adjacent second molar showed no significant difference between marginal flap and paramarginal flap before surgery and at 2 weeks and 4 weeks after surgery [P>0.05]. No significant difference was found with the use of paramarginal flap instead of traditional marginal flap in the removal of impacted mandibular third molar

Awareness of needlestick injuries among the dental health professionals at Lahore medical and dental college

Health care associated transmission of blood borne diseases has always been an important public and medical concern worldwide. Objective of this study was to assess the degree of awareness of needle stick injuries among dental health professionals working at LMDC. Dental students during clinical training are at high risk for needle stick injury while administering local anesthesia. This fact has been known for the past few decades to be the founder of several blood borne diseases such as Hepatitis B [HBV], C [HCV] and AIDS [HIV]. Several studies have reported the high incidence of such practice among dental students and graduates. Study was conducted on 139 Dental Health Professionals at the Lahore Medical and Dental College in the year 2010 based upon questionnaire developed by a team of senior faculty members. Exposure to needle stick injury was found among 63[45%] subjects. 118 [85%] of Dental health professional were found to be aware of precautionary measures and first aid management for a needle stick injury respectively. The number of Dental Health Professionals who had been vaccinated for Hepatitis B [HBV] 121 [87%] and those who had never been vaccinated were 18 [13%]. Among nonvaccinated group 90% were Dental assistants. Proper work practices and continued Education seminars and workshops regarding awareness of needle stick injuries have the prime importance of creating awareness. The prevention and management protocol for such injury should be displayed in the clinical departments of all institutions. These steps will assure safe practicing methodology among dental health professionals

range of inter-incisal opening among university students of Ajman, UAE

The aim of this study was to investigate the average maximum mouth opening and range of mouth opening in a representative sample of the adult students of UAE. Maximum mouth opening was studied in 450 adult students age range 19-24 years of Gulf Medical University Ajman, UAE. Those with clinical history of TMJ involvement, trauma, infections, dental prosthesis on the anterior teeth, congenital anomalies in the maxillofacial region were excluded from this study. The measurements were taken twice and mean of the two values were recorded. The average mouth opening of males [59.74 + 5.26 mm] subjects was higher as compared to female [46.50 + 3.32 mm] with significant, p-value 0.000

Pediatric parasymphysis fracture management a case report

Children are uniquely susceptible to craniofacial trauma because of their greater cranial mass to body ratio and their treatment is unique due to the psychological, physiological, developmental and anatomical characteristics of children. Below the age of 5, the incidence of pediatric facial fractures in relation to the total is very low ranging from 0.6-1.2%. This case report includes management of displaced left mandibular parasymphysis fracture, operated at Ghurki Trust Teachin Hospital, Lahore, Pakistan in Sept 2009. Conservative approach was used for fracture reduction and fixation using custom made mandibular splint stabilized through circum mandibular wiring. The procedure is less traumatic with lesser post-operative complications compared to open reduction and internal fixation with restoration of aesthetics and function post operatively and is commonly practiced worldwide. The purpose of presenting this case report is to provide an insight on maxillofacial injuries in pediatric patients for management of this unique and highly specialized area of traumatology

rational management approach to an odontogenic keratocyst [a long term follow-up]

Odontogenic keratocyst [keratocystic odontogenic tumor] is a destructive jaw lesion with the propensity to recurrence. The atypical symphyseal odontogenic keratocyst was managed with a defined protocol which entailed diagnosis, treatment with enucleation along with peripheral ostectomy and rehabilitation. A long term follow-up schedule was provided to the patient to observe the recurrence behavior of this cyst. In post operative phase, no complication was noticed regarding wound healing and recurrence. Therefore, defined treatment protocol and long term follow-up may provide better means to manage cysts with such indistinct recurrence behavior. Future treatment may involve molecular-based modalities which may reduce or eliminate the need for aggressive surgical management

audit of the pathologies associated with impacted wisdom teeth

The purpose of this study was to find out the types of pathologies that can arise in association with impacted wisdom teeth. Two hundred consecutive patients scheduled for extraction of one or more of their impacted wisdom teeth were evaluated clinically and radiographically. Orthopantogram [OPG] was the standard radiograph. 194 [97%] of the teeth were associated with pathologies. Pericoronitis was the most common condition followed by caries, periodontal disease, facial space infections, cyst / tumors and resorption of adjacent second molar. Six [3%] of the teeth were extracted for orthodontic reasons. Younger patients had acute reversible conditions whereas with increasing age chronic destructive lesions became more prevalent. Retaining impacted teeth can lead to recurrent pericoronal infections and damage to adjacent structures

Efficacy of peripheral glycerol injection in the management of trigeminal neuralgia

To evaluate the degree and duration of pain relief obtained with peripheral glycerol injection in patients with idiopathic trigeminal neuralgia. Interventional, Clinical trial. Fifty [50] medically resistant and non-surgically treated patients were selected. In the study group twenty five [25] patients received 1 ml glycerol injections in the involved peripheral nerve, after administration of local anaesthesia. The control group of twenty five [25] patients received 1 ml normal saline injections. All the patients [25] in the control group [normal saline] had no pain relief. Out of the 25 patients who received glycerol injections 24 [96%] patients had pain relief for 3 months. At six months nineteen [76%] patients had pain relief. At one-year follow up eleven patients [44%] continued to have pain relief. Another eleven [44%] patients were pain free with minimal dose of medication. There were no significant complications reported after the glycerol injections. The combination of efficacy and decreased morbidity makes peripheral glycerol injections a useful treatment modality for medically intractable Trigeminal Neuralgia patients

cephalometric study of the effects of screw height on rapid maxillary expansion

This study was undertaken to compare the skeletal expansion effects of rapid maxillary expansion [RME] using either a shallow or deep height of Hyrax expansion screw. The study includes 16 patients with narrow maxilla and mild to moderate crowding of the maxillary arch. Rapid maxillary expansion was performed in half of the patients with the shallow Hyrax expansion screw and other half with the deep screw. The angular and linear changes related to the maxilla were analyzed with Wilcoxon signed ranking test comparing posterior anterior [PA] cephalometric films obtained before and after rapid maxillary expansion. Both appliances were equally effective in skeletal expansion of maxilla. The deep screw appliance was more effective in increasing the nasal width
