Background:Histological grading is an important diagnostic tool to predict the clinical and biological behaviour of cancer. Cervical lymph node metastasis indicate poor prognosis of oral cancer. Considering economical status of a third world country, Anneroth's grading system is less expensive, more informative than TNM staging and Broder's grading system. Anneroth's grading system also shows co-relationship with lymph node metastasis. So we are trying to evaluate the Anneroth's grading as a standard one among these three system.Objective:To study the grading of histological malignancy according to Anneroth's classification of biopsy specimens in relation to metastasis in the cervical lymph nodes and comparing the Anneroth's with the other two recognized classifications.Materials and Methods:Fifty(50) patients with oral squamous cell carcinoma was included in the study. Specimen of 35 non-metastatic tumors were compared with 15 metastatic cases. All of the patients were graded to TNM, Broder's and Anneroth's system. TNM is clinical assessment and Broder's is based on only differentiation of cells. On the other hand, six parameters of Anneroth's gives a detail about the morphology of the tumor, invasion criteria in the host tissue and show its correlation with lymph node metastasis. Scoring system of Annearoth's grading indicates demarcation points of worseness of tumor and signifies the possibility of lymph node metastasis.Results:Both Anneroth's(P=0.002) and Broder's grading(P=0.012) have been significant but Anneroth's one is more significant then Broder's.Conclusion:Anneroth's classification can be taken as a standerd diagnostic factor and predictive factor of lymph node metastasis.

Occlusal splint plays a great role in the treatment of internal derangement of temporomandibular joint. Temporomandibular disorders affect 25 % of the population of the world. The purpose of the study was to elucidate the effectiveness of occlusal splint in reduction of pain, increase mouth opening, elimination of clicking sound. This randomized controlled clinical trial was done on 26 patients in two groups. Group A received occlusal splint and Group B received medications with supportive care. Monthly follow-up was done for a period of four months. In Group A and Group B, preoperative mean of mouth opening were 36.31 mm; and 39.77 mm. pain score 4.54 cm, clicking in 76.9% and 84.6% patients respectively. After 4 months of follow-up mouth opening 50.69 mm and 43.15 mm, pain score 0.154 cm and 0.69 cm, clicking 30.8% and 76.9% patients in both groups respectively. It may be conclude that the occlusal splint is highly efficient than medication and supportive care for managing of internal derangement of temporomandibular joint.

Pedicled flaps play an important role in cancer treatment centers, particularly in developing and emerging countries. Although different flaps can be used for facial reconstruction but Pectoralis major myocutaneous flap is still considered the workhorse for maxillofacial reconstruction because of simple procedure and high success rate, while other flaps of facial region ranging from pedicled to free flaps require greater surgical skills along with unpredictable results.The aim of this study is to find outcomes of Pectoralis major myocutaneous flap in reconstruction of middle and lower facial regions. Main outcome measures are vitality of the Pectoralis major myocutaneous flap, donor site morbidity and recipient and donor site complications.This study was carried out on 36 patients in BSMMU and Health & Hope Hospital in Dhaka from 1st April 2005 to 30th June 2011 who require soft tissue reconstruction of defects of middle and lower facial regions. The age and sex of the patients and size of defect were analyzed.  Vitality of Pectoralis major myocutaneous flap, donor site morbidity and donor and recipient site complications were studied. In this study, male female ratio was 13:5; mean age 50 the success rate of was 100%. All of the flaps were vital but 13.8% of the flaps had partial loss of flap.Pectoralis major myocutaneous flap is a versatile flap as it can not only provide skin and  mucosal cover simultaneously, but also provide adequate muscle bulk for through and through defects. It doesn't cause any hindrance in mandibular movements. DOI: http://dx.doi.org/10.3329/akmmcj.v3i2.11690 AKMMC J 2012: 3(2): 23-29

Squamous cell carcinoma is the most common oral malignancy. Betel quid, betel quid with tobacco, smoking, alcohol consumption, mechanical irritation, genetic are the most important risk factors for Oral Squamous Cell Carcinoma (OSCC). The aim of the study was to determine the role of habitual risk factors inOral Squamous Cell Carcinoma.  Materials and Methods: This is a cross-sectional study for the determination of the risk factors of OSCC over 2 years period of January 2011 to December 2012. Department of Oral & Maxillofacial Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Department of Oral & Maxillofacial Surgery, Dhaka Dental College Hospital, Dhaka,National Institute of Cancer Research & Hospital (NICRH), Mohakhali, Dhaka and Health and Hope Hospital, Dhaka from January 2011 to December 2012  Results:250 patients, comprising 44% male and 56% female were included in the study. Overall mean age was 55.94±10.93 years. The patients of OSCChavemost common habit of betel quid with tobacco 124(49.6%), then betel quid with tobacco and smoking 49(19.6%), betel quid with tobacco and Gul 19(7.6%), only smoking 13(5.2%), Betel quid without tobacco and smoking 13(5.2%), betel quid without tobacco 12(5.2%), betel quid with tobacco and catechu (Khoir) 4(1.6%), betel quid with tobac- co, smoking and gul 3(1.2%), betel quid without tobacco,smoking and alcohol 2(0.8%), betel quid without tobacco and gul 2(0.8%), betel quid without tobacco, smoking and gul 1(0.4%), betel nut chewing 1(0.4%), mechanical irritation but no habit 5(2.0%) and no habitual history 2(0.8%).  Conclusion: According to this study betel quid, betel quid with tobacco, gul, smoking are the important risk factors in OSCC.Update Dent.
