Abstract:Aim: Oral health problem is one of the major health problems during pregnancy in both developing and developed countries. This cross-sectional study was carried out to assess the oral health status of the pregnant women attended some selected mothers and children welfare centers (MCWCs) in Bangladesh. Methods: Data was collected by face-to-face interview and clinical examination with the help of a structured questionnaire and check list. Results: Half (50.0%) of the pregnant women was of 15 to 20 years old and their mean age was 22.28±4.22 years. Thirty eight percent (38.2%) of the women had primary education and 78.4% did not visit any dentist. Majority (93.1%) used tooth brush before breakfast and most (84.4%) of them had no information about oral hygiene care. Regarding oral health status, 87.3% had caries affected teeth and 94.1% had gingivitis. Presence of gingivitis and calculus were higher among the elder women (21-35 years) than the younger group (15-20 years) which was 92.2% among the housewives. Gingivitis was significantly higher among the women in low income group (95.7%) than the other income groups (X 2 = 5.80, p<0.05). Conclusion:The study findings recommended for provision of essential dental health services to the pregnant women for prevention and control of various dental health problems during pregnancy.

Sterilization of bacteria in root canal system is one of the prominent problems. Some bacteria could remain in root canal even after using conventional medicaments. Evidences suggested that Enterococcus faecalis (E. faecalis) caused substantial root canal infections. So, elimination of such organism is important to achieve treatment success. Research hypothesis: Sterilization of root canal with Lesion Sterilization and Tissue Repair (LSTR)-3mix MP Therapy is thought to be more effective against E. faecalis comparing to single antibiotic. Methods: In-vitro cross-sectional with interventional type of study to observe the zone of inhibitions by E. faecalis culture using LSTR- 3mix (metronidazole, ciprofloxacin and minocycline) and calcium hydroxide (control). Results: The results strongly recommended that LSTR-3mix sufficiently able to inhibit E. faecalis growth. DOI: http://dx.doi.org/10.3329/cdcj.v9i2.12311 City Dental College J.

Purpose: The objective of this study was to evaluate the correlation between maxillary canines and the facial landmarks including interalar width (IAW) and intercommissural width (ICoW) in a group of Bangladeshi people. Materials and methods: One hundred Bangladeshi subjects aged 18~35 years were selected. Irreversible hydrocolloid impression of the upper arch was taken and a cast was poured with dental stone.The interalar width (IAW) and intercommissural width (ICoW) were measured using digital vernier caliper. Intercanine tip (ICTW) and width of the distal surface of the canine (WDC) were measured from the cast using digital caliper. Results: The correlation between ICTW-IAW was 0.246. There was  no correlation between ICTW-ICoW. The correlation between WDCIAW and WDC-ICoW were 0.342 and 0.235 respectively (p< .05). Conclusion: Both interalar width and intercommissural width had a weak correlation with the position of maxillary canine in this Bangladeshi subject group. For the construction of a pleasing and harmonious complete denture esthetic and phonetic outcomes are recommended to be considered in combination with facial landmarks.

Cessation of the root development occurred by traumatic injury and as a sequence of caries prevents obturation of the root canal during endodontic treatment and subsequent treatment like fixed prosthesis. Thus, the goal of apexification was to obtain an apical barrier to prevent the passage of toxins and bacteria into the periapical tissues from the root canal and to induce an apical barrier against which GP points can be condensed. Apexification has been carried out from long time where calcium hydroxide is the widely used material. Calcium hydroxide gained the widest popularity. It is bactericidal in nature with an alkaline pH that may be responsible for stimulating apical calcification. Despite its widest acceptance, it has some disadvantages including variability of treatment time, difficulty in patients follow up, delayed healing, needs multiple visits to the completion to induction of calcific barrier formation and it weakens the dentin of root. Thus, the scientists and clinicians felt urge to introduce new materials and techniques that will help to the quick resolution of the apical radiolucency and to form the apical barrier. MTA (mineral trioxide aggregate), a recently introduced material is successfully used in the treatment of apexification. Many renowned scientists and clinicians worked on this materials and got very good results. Recently a clinical study has been published showing the effects of a combined medicament prepared by mixing calcium hydroxide with cefadroxil on the resolution and formation of apical barrier. Although it was a multi visits treatment compared to the treatment with MTA but showed promising results in the treatment of apexification in presence or absence of radiolucency. Thus, this review article will expose the recently invented materials and techniques which will provide a helpful guide for the clinicians to perform apexification. This review article has been prepared from the internet information and reviewing the recently published papers and texts. DOI: http://dx.doi.org/10.3329/cdcj.v9i2.12320 City Dental College J.
