Assesment of recurrence of odontogenic keratocysts treated with different surgical modalities -nine years follow up of disease

The purpose of this study was to determine the Recurrence rate of odontogenic keratocysts [OKC] and association of recurrence with various surgical modalities. It was cohort analytical study. Eighty-two odontogenic keratocysts cases treated at Oral and Max illofac ial department Armed Forces Institute of Dentistry, Rawalpindi farmed the study subject, and were followed for a period of 9 years from 2004 to 2013. Recurrence ofOKCs were evaluated from 1-9 years after surgical treatment by clinical and ra-diographic means and correlated with various treatment modalities. The most frequent site affected by OKCs was the posterior mandible including body, angle and ramus. Patients were followed for recurrence. 16 patients were lost to follow up and this journal was 14 cases of recurrence out of 66 were treated with varying modalities [21.2%]. Patients treated conservatively with marsupialization or enucleation alone demonstrated higher recurrence rates [100% and 50% respectively]. Odontogenic keratocyst is an aggressive cyst associated with high recurrence. Surgeons should decide on various modalities as per requirement of the case. Although resection carries least risk of recurrence, it should be limited to recurrent and aggressive OKCs. The outcomes of enucleation combined with peripheral ostectomy and chemical cauterization is reasonably acceptable

Effects of pre-operative submucosal dexamethasone injection on the postoperative swelling and trismus following surgical extraction of mandibular third molar

To determine the effects of pre-operative submucosal dexamethasone injection on postoperative swelling and trismus following surgical extraction of mandibular third molar. Randomized controlled trial. Department of Oral and Maxillofacial Surgery, Armed Forces Institute of Dentistry [AFID], Rawalpindi, from October 2009 to March 2010. A total of 100 patients aged 18 - 40 years with good periodontal health and mesioangular impaction were divided in two treatment groups [50 in each group]. Group-A received prophylactic 4 mg submucosal dexamethasone intraoral injection and Group-B acted as control group. Facial swelling and trismus were assessed at baseline, 2nd and 7th postoperative days. Data was analyzed using SPSS-10. There were 35 [70%] males and 15 [30%] females in group-A and 34 [68%] males and 16 [32%] females in group-B. Surgical time ranged from 30 - 50 minutes [mean = 40.62 +/- 4.886 minutes] for group-A and 33 - 50 minutes [mean = 42.12 +/- 4.543 minutes] for group-B. Administration of dexamethasone had statistically significant effect in reduction of swelling and trismus on second postoperative day [p < 0.05] in group-A. Pre-operative 4 mg submucosal dexamethasone injection was significantly effective in reduction of postoperative swelling and trismus

Accuracy of Pederson and modified Parant scale for predicting difficulty level of mandibular third molars

To determine the accuracy of Pederson and Parant Scale for predicting the difficulty level of mandibular third molar extraction. Prospective cross-sectional, 6 months from January 2012 to June 2012. All consecutive patients who presented for the extraction of impacted third molars were included in the study. Orthopantomograms (OPGs) were advised and on these OPGs third molars were classified as easy, moderate or difficult according to standard Pederson scale. Similarly modified Parant scale was utilized to predict the difficulty of removal of third molars. Root pattern was also noted on the OPG. These parameters were then compared with peri-operative parameters like time taken for extraction and need for crown or root sectioning using Chi Square test. A p value of 0.05) while significant results were obtained in case of Parant Scale (p value<0.05). Statistically significant results were seen for root pattern and level of difficulty (p value<0.05). These scales failed to predict difficulty level of tooth removal accurately especially in cases of distoangular impactions. When combined with root pattern, the accuracy of prediction gets significantly better.

Frequency of xerostomia in patients suffering from hepatitis B and C

The objective of the study was to assess the frequency of xerostomia in patients infected with hepatitis B and C presenting to the oral and maxillofacial surgery department of Rawal Institute of Health Sciences, Islamabad from October 2011 to February 2012. It was carried out as a prospective cross sectional study. All patients who gave the history of being infected with hepatitis B or C were included in the study. They were asked about the sensation of dryness of mouth and then were clinically evaluated for the presence of xerostomia by putting a mirror against the mucosa. Sticking of mirror to the mucosa was taken as a positive result. 38 patients presented to the oral surgery department, out of these, 6 were males and 32 females [1:5.3]. Eight [21.1%] had hepatitis B while 30 [78.9%] were suffering from hepatitis C. Xerostomia was seen in 8 [26.7%] patients with hepatitis C. None of the patients with hepatitis B presented with xerostomia. Chi Square test was used to analyze the association of xerostomia with therapy for hepatitis but no statistically significant association was observed [p>0.05]. Xerostomia may be a finding in patients with chronic liver disease and treating clinicians should be aware of it and should treat it to improve patients' quality of life
