Plaque score and gingival health status among 6-12 years old children in hyderabad division

The objective of this study was to evaluate the plaque score and gingival health status among 6-12 years old school children. This cross sectional study was done from 15th July to 10th August 2014 among the students of Matiari [Rural Area] and Hirabad Hyderabad [Urban Area]. Schools were selected on convenient basis. Age ranged from six to twelve years and only boys were included in the study. All clinical dental examinations were conducted in schools with mouth mirror and explorer in the day light. Plaque index and gingival index developed by Loe and Silness were used for each student to record the plaque score and gingival condition. The plaque disclosing tablet [Eviplac Pastilhas; Biodinamicas TM], was used to identify the plaque score. All the students were asked about routine oral hygiene procedures. Data were analyzed in statistical package for social sciences [SPSS] version 16. Quantitative variables are presented in percentages. Mean and standard deviations were computed for qualitative variables. Chi-square test and independent sample t-test were applied to see the significant association. Total one hundred seventy six school children were included in this study; ninety six were from rural area and eighty from urban area. The mean age was 15.85 +/- 7.773. The gingivitis was seen in 80.7% students. Gingivitis was more in the rural children than from urban areas which was statistically not significant. The mean plaque score was 39.63 +/- 19.15 in present study. The independent sample T-test analysis revealed no significant difference between rural and urban students. Gum bleeding was more common in rural school students which is statistically significant. It is concluded that there was a higher gingival inflammation in present study population. Urban students had good gingival condition and low mean plaque score than rural students. Mild type of gingivitis was more common in rural students

Evaluation of anesthetic efficacy of 4% articaine as buccal infiltration vs 2% lidocaine as IANB in the mandibular 1st molar with irreversible pulpitis

The purpose of this prospective, randomized, study was to compare the anesthetic efficacy of 4% articaine with 1:100,000 epinephrine and 2% lidocaine with 1:200,000 epinephrine for buccal infiltration and inferior alveolar nerve block respectively in patients experiencing irreversible pulpitis in permanent mandibular first molars. Sixty emergency patients diagnosed with irreversible pulpitis of a mandibular first molar ran-domly divided into two groups. Thirty patients received buccal infiltration of 1.7 ml of 4% articaine with 1:100,000 epinephrine and thirty patients received standard inferior alveolar nerve block with 1.8 ml of 2% lidocaine with 1:200,000 epinephrine. Endodontic access was begun 10 minutes after solution deposition, success [anesthetic efficacy] was defined as none or mild pain [Visual Analogue Scale recordings] on endodontic access preparation or pulp extirpation. Twenty-two patients out of 30 did not experience pain with 4% articaine [success = 52.4%] and 20 out of 30 patients did not experience pain in 2% lignocaine group [success = 47.6%]. There was no statistically significant difference between the articaine formulation as buccal infiltration and lidocaine formulation as IANB with regard to anesthetic success [p value =0.220]. Even though buccal infiltration of 4% articaine and IANB of 2% lidocaine were equally effective, buccal infiltration can be considered a viable substitute in IANB for anesthetizing mandibular first molar with irreversible pulpitis

Impacted mandibular third molar surgery; the role of dexamethasone in postoperative swelling and trismus

The objective of this study was to evaluate the therapeutic effect of dexamethasone in post-operative edema and trismus after impacted third molar surgery. It was a prospective randomized control study carried in Department of Oral and Maxillofacial surgery, BADC, Larkana from March 2012 to Feb 2013. Patients age between 20-45 years of either gender; unilateral mandibular impacted third molars [right or left] were included. Patients divided in two groups by using random allocation number. Patients in Group-A were given intramuscular 8 mg dexamethasone 1 hour before surgery and four tablets [2mg] dexamethasone orally immediate postoperatively and 24 hours after surgery. The facial swelling was checked before surgery, after 24 hours [1st day], after 48 hours [2nd day], after 72 hours [3rd day] and on 7th postoperative day Inter-incisor distance was checked on every follow up. Data was analyzed by SPSS version 17. Mean and standard deviation was calculated for age and gender. Mean and SD of facial swelling and mouth opening was calculated before extraction, on 1st, 2nd, 3rd and on 7th post-operative day in both groups. The dexamethasone group showed significant reduction in swellingcompared with control group at all intervals. Dexamethasone resulted in significantly less trismus than controls on day 2 postoperatively, but there was no significant difference among the groups at 7thday. Dexamethasone is effective in minimizing swelling and trismus after removal of impacted lower third molar and improves the social life of individual

Forehead flap for reconstruction of maxillofacial region defects

OBJECTIVES: To assess the efficacy and efficiency of forehead flap in reconstruction of maxillofacial region defects

STUDY DESIGN: Descriptive study

PLACE AND DURATION: Department of Oral and Maxillofacial Surgery King Edward Medical University/Mayo hospital Lahore, from November 2009 to June2012

METHODOLOGY: This study was carried out on 30 [Thirty] consecutive patients, of either sex, who required soft tissue reconstruction of maxillofacial region including oral cavity defects due to trauma, infection or after tumor ablative surgery. Follow up was done for four months and on every follow up visit, patients were questioned about the degree of satisfaction, with mouth opening and donor site aesthetics. Cosmetic deformity judged subjectively

RESULTS: The axial pattern fascio-cutaneous flap, for the reconstruction of maxillofacial region with oral cavity defect, performed in 30 patients. Success rate of the flap was 100%, with only partial necrosis of the flap in 1 case. Subjective assessment of the donor site however showed suboptimal results with 30% [n-9] patients moderately satisfied and 20% patients [n-6] were unsatisfied

CONCLUSION: Forehead flap is a reliable technique for reconstruction of maxillofacial region defects

Etiology and incidence of maxillofacial skeletal injuries at tertiary care hospital, Larkana, Pakistan

The objective of this study was to determine the causes, incidence and distribution of maxillofacial injuries. This was a descriptive study performed at the tertiary care hospital of Larkana [Accident and Emergency Department of Chandka Medical College, Hospital and Outpatient's Department of Bibi Aseefa Dental College Hospital, Larkana] from 1st February 2011 to 30th August 2013. Two hundred and eighty eight patients of maxillofacial injuries were included in this study patients less than 11 years of age, suffering from neurological disorders and patients with isolated cases of dental and nasal injuries or only with facial lacerations were excluded. Information and data were collected from history, clinical examination and surgical preoperative records of each patient. Results showed that the most common etiology was road traffic accident [170] 59%, interpersonal violence [31] 10.76%, gunshot injuries [28] 9.7%, falls [19] 6.5% and others [40] 13.88%. The mandible was the most frequent bone fractured, which accounted for [148] 50.38% followed by zygomatic complex [52] 18% and [24] 8.3% maxillary bone. Fracture in combination form involved [64] 22%. It was concluded that road traffic accident was the most common etiological factor of maxillofacial skeletal trauma, while second most common cause was the interpersonal violence. Mandible was the most commonly fractured bone

Prevalence of dental caries in Bibi Aseefa Dental College, Larkana areas

The study was conducted for the first time in Bibi Aseefa Dental College [BADC], Larkana from April 2012 to March 2013 to evaluate the prevalence of dental caries in Larkana city and its adjoining areas, and to know the effect of age, gender, socioeconomic status, oral hygiene status and attitude towards dental awareness to caries prevalence. It was a Cross-sectional study. Six hundred patients between 13-20 and 21-30 years of age were selected from dental OPD, BADC, Larkana. The dentition was examined using WHO 1997 guidelines. The results were tabulated and statistically analyzed. Chi-square test was used to evaluate results. The overall caries prevalence in 13-20 years and 21-30 years old groups in Larkana city and adjoining areas determined was 100%.The mean DMFT value was higher i.e. 3.42 in age group 13-20 years. Besides age, the gender, socioeconomic status, oral hygiene status and attitude towards dental awareness were significantly related to dental caries prevalence. It was concluded that prevalence of dental caries in Larkana city and its adjoining areas was found considerably higher, and it was significantly related to bad oral hygiene and socioeconomically deprived patients which indicates lack of awareness and motivation. Prevalence of dental caries decreased with increasing age

Validity of different methods for MB-2 canal location in permanent maxillary molars

The purpose of this study was to evaluate the effectiveness of naked eye examination and Dental-operating microscope [DOM] examination for the location of second mesiobuccal canal [MB-2] in extracted maxillary first and second molars, considering the sectioning of the tooth as gold standard for the location of MB-2. This was a cross-sectional comparative study. One hundred extracted permanent maxillary first and second molars [50 of each] were stored in 10% neutral formalin. Using high speed headpiece standard endodontic access cavities were prepared. Initially, the mesiobuccal, distobuccal and palatal canals were located. Subsequently, the location of MB-2 canal was attempted by examining the pulp chamber floor with naked eye using only an endodontic explorer and canal confirmed with 10# K-file. MB-2 canal orifice was either located or not located with this method. Teeth in which MB-2 canal was not located were further explored under DOM. Yet again MB-2 canal orifice was either located or not located. Finally the mesiobuccal roots of each tooth were sectioned. The sections were explored with endodontic explorer and 10# K file with the adjunctive use of DOM at a magnification of 12x to decide the real presence of MB-2 canal. 42% and 60% of MB-2 canals in maxillary first molar, 20% and 38% of MB-2 canals in maxillary second molar were detected with naked eye and with DOM examination respectively. While 66% and 42% of MB-2 canals were actually present in maxillary first and second molar respectively as confirmed by gold standard [sectioning of teeth]. It is concluded that DOM examination may be more effective for location of the MB-2 canal than naked eye examination
