Current restorative materials with high fluoride release generally have lower mechanical properties. Therefore they may not be as durable clinically as lower fluoride release materials, particularly in load bearing areas. The aim of the present study is to explore the fluoride release and recharging ability as well as its compressive strength of the newly developed material called Giomer. The name Giomer is a hybrid of the words Glass Ionomer and Composite. Giomer contain a revolutionary PRG (Pre Reacted Glass) filler technology. They have properties of both conventional Glass Ionomer (fluoride release and recharge) and resin Composite (excellent esthetics, easy polishability and biocompatibility). MATERIALS & METHODS: Seven disk specimens of Giomer, Compomer and Glass Ionomer restorative materials were prepared for measurement of fluoride release and recharge using Ion Chromatography (IC) anion analyzer machine. Another seven disk specimens of Giomer, Compomer and Composite restorative materials were prepared for measurement of compressive strength using Universal Testing Machine (UTM). RESULTS: The value of compressive strength of Giomer is greater than that of Composite and Compomer but the fluoride release capability of Giomer becomes low in comparison to Glass Ionomer but not significant in comparison to compomer. CONCLUSIONS: Giomer have high compressive strength (271 Mpa) and an initial fluoride (1.41 ppm) release. It also exhibit fluoride recharge capabilities. So, Giomer to be a better restorative material other than any fluoride releasing materials. DOI: http://dx.doi.org/10.3329/updcj.v2i2.15533 Update Dent. Coll. j: 2012; 2 (2): 28-37

Diabetic mellitus is a burning issue in medical ground. If Pulp or periapical pathology develops on diabetic patient, it may need extra attention to manage by root canal treatment. Because very often diabetic patients develop hyperglycemia, leading complex immune response and enhanced virulence of certain microorganism and commonly cause exaggerbration of inter appointment clinical complain like, pain and swelling known as flare-up. The purpose of this study was to clinically examine the development of endodontic flare-up following endodontic intervention in control and in diabetic patient group. In the present study, overall incidence of inter-appointment flare-up in diabetic patients was found to be 19% whereas in non-diabetic group, incidence was 8% that was almost half to the diabetic group. So, this study conclude that root canal treatment can be comfortably done in controlled diabetic patient but need extra care during endodontic treatment if the patient is suffered from uncontrolled diabetes mellitus.

Teeth once designated obsolete for rehabilitation and deemed for extraction should be re-evaluated for salvaging two thirds or even one third component of the individual teeth. Advances in dentistry, as well as the increased desire of patients to maintain their dentition, have lead to treatment of teeth that once would have been removed. In order to carry out this present day mandate, periodontally diseased teeth with severe bone loss and/or mandibular molar teeth exhibiting furcation invasions may well be retained by removal of one or more of their roots. This article describes a simple procedure for root amputation in mandibular molar and its subsequent restorations.

Introduction: The use of Bioceramic sealer in the obduration of the root canal system has been expected by many of the previous studies. However, the clinical outcome has not yet been established. Objective: To compare the effectiveness of bioceramic and calcium hydroxide based root canal sealer in treatment of non-vital permanent teeth with periapical lesion (Periapical periodontitis). Materials and Methods: A total 100 mature permanent anterior teeth were selected after clinical and radiological examination which had non-vital pulp with periapical lesion. Clinically pulp vitality test, palpation and percussion test was performed maintaining standard procedure. Following cavity preparation and biomechanical preparation, each canal was obturated either with bioceramic (Endosequence BC) or calcium hydroxide based sealer  (Sealapex, Kerr). All participants were evaluated immediately after obturation, at  3 and 6 months for the assessment of change in size of periapical lesion, condition of periodontal ligament space, lamina dura and incidence of post-operative pain, swelling. Statistical analysis was performed using Chi- square(X2) test and t-test. A value of p<0.05 was considered as statistically significant. Results: Bioceramic was more effective in reducing the lesion size than that of calcium hydroxide. At 6 months, the mean lesion size was reduced from 3.52±0.7 to 1.30±0.462 mm in Bioceramics and from 3.48±1.07 to 1.58± 0.498 mm in sealapex treated teeth.. Furthermore, 98% of bioceramic treated teeth and 94% of sealapex treated teeth showed absence of swelling. The differences between two groups were statistically significant (p<0.05). Conclusion: In this short period of study, Bioceramics based sealer seems to be more effective than calcium hydroxide based sealer in repair of periapical lesions of the nonvital teeth. Update Dent.

:Mandibular molars often have an additional root located lingually (the radix entomolaris) or buccally (the radix paramolaris). If present, an awareness and understanding of this unusual root and its root canal morphology can contribute to the successful outcome of root canal treatment. This report discusses endodontic treatment of a mandibular molar with a radix entomolaris, which is a rare macrostructure. The prevalence, the external morphological variations and internal anatomy of the radix entomolaris are described. Avoiding procedural errors during endodontic therapy demand an adapted clinical approach to diagnosis and successful non-surgical endodontic treatment. Introduction:The prevention or healing of endodontic pathology depends on a thorough chemo mechanical preparation of the root canals before a dense three-dimentional obturation of the canals. An awareness and understanding of the presence of unusual root canal morphology can thus contribute to the successful outcome of root canal treatment.

A descriptive cross-sectional study was conducted among 96 dental surgeons at selected private dental hospitals in Dhaka city (North). The objective of the study was to find out musculoskeletal disorders within dental surgeons at selected private dental hospitals in Dhaka city during the period between September to November 2012.Convenient sampling technique was used and information was gathered by face to face interview with a pre tested semi structured questionnaires. Among the respondents, 43.8% were of in the age group of 36 -40 years age, 18.8% were in the age group of up to 35 years, and 13.5% were in the age group of 41 -45 years and 19.8% in the age group of over 50 years. The 67.7% were male and 32.3% were female respondents. By professional educational level 36.4% were Bachelor in Dental surgery and 63.5% were post graduated. . Among the respondents 79.2% who had professional experience more than 10 years missing in practice due to MSD more than 29.2%who had professional experience more than 10 years or less. The reduction and prevention of MSDs among dental surgeons should include their education and awareness regarding the importance of work related risk factors.

In appearance related society that we live in , the younger adolescent patient caneasily become self conscious if their teeth are different to others. A common from of microdontia which affect the maxillary lateral incisor is known as "peg lateral". Treatment approach has to be case specific and depends on the condition of primary predecessor, number of missing teeth, status of occlusion and patient preference.This clinical report describes the treatment of both sided peg-shaped lateral incisors that were restored with resin composite laminate veneers. The aim of the treatment is to close the diastema and restore the contours of the tooth. These simple procedures may be a cost -effective treatment alternative to restore the esthetics of these teeth and may prove particularly growing patients before more definitive restorations can be considered.

Aim: To seal with Mineral trioxide aggragate(MTA) and make a sizeable communication between the root canal system and the periradicular tissue and provide a barrier because of lack of apical constriction.Summary: A 9 year old girl who had met with trauma about six years ago, before she visited department of Paediatric Dentistry , Update Dental College,Dhaka,Bangladesh for the treatment of mandibular right lateral incisor. The case was diagnosed as necrosis of pulp with open apex. After proper isolation access opening and biomechanical preparation was performed with 1mm short of the radiographic apex and calcium hydroxideused as intra canal medicament. After 15 days MTA was placed in the canal till a barrier of 4mm was achieved. Later obturation was done using lateral condensation technique.Size of the periapical lesion was almost decreased after one year of follow up. Followup was done after 1 month, 6 months and 1 year later.Update Dent. Coll. j: 2015; 5 (1): 21-25
