Abstract
The high cariogenicity of all black cola drinks is recognized by all oral health care professionals. It has been proven that black cola drinks pose a threat to the integrity of tooth structure. Despite the presence or absence of artificial sweeteners in cola drinks, both regular and diet soft drinks still contain phosphoric and citric acid, which contributes to the total acidic challenge potential on enamel. Fourteen children (8 to 15 years of age) were recruited with DMFT +deft ≤3. Subjects were instructed to stop brushing 48 h prior to the appointment. Plaque samples collected and dissolved in the test beakers having 1 ml of double distilled water and pH was determined immediately inherent pH of the test drinks was measured. Five minutes after the consumption of each drink, the plaque sampling was done. The pH was recorded after 10, 20, 30, 40 and 60 min of the post consumption period. All the test drinks dropped the plaque pH below the critical pH indicating that the entire four carbonated beverage were capable of causing dissolution of enamel. That all carbonated beverages have virtually the same effect on acid production in plaque and thus are equally erosive.
Key words: Diet coke, regular coke, diet pepsi, regular pepsi, pH, saliva.

Abstract
LASER (light amplification by stimulated emission of radiation) devices transform light of various frequencies into chromatic radiation that is capable of mobilizing heat and power when focused at a close range. They are usually named after the active medium employed, which can either be a container of gas, a crystal, or a solid-state semi conductor.
Key words: LASER, light, radiation, semi conductor.

Abstract
The aim of this study was to assess the awareness and prevalence of career-associated medical conditions among Dental Surgeons, Dental Hygienists and Final year students at the University of Ghana Dental School. 55 volunteers were randomly selected for this study. They included 26 Dental Surgeons, Five (5) Dental Hygienists/Therapists and 20 final year dental student. A self-administered questionnaire was used to capture the data which was analyzed using Statistical Package for Social Sciences (SPSS) version 16. The age of the respondents ranged between twenty and sixty-six years. There was a high level of awareness (>90%) of the major career associated medical conditions. Human Immunosuppression Viral infection (HIV) was the commonest occupational medical condition known. Over 40.0% of the total respondents had had needle stick injury before and17.6% within the past 6 months. Sixty-five (65%) percent of the respondents had attended a workshop on the prevention of occupational hazards, while 75% of the respondents had no knowledge on the institutional policy on waste management. Although there was a high level of awareness of career associated medical conditions; the prevalence was still high which is indicative of poor practice and behavior towards preventive measures.
Key words: Career, dentistry, Medical condition, Occupational hazards, Personal protective equipment (PPE), burnout.

Abstract
Poverty, wars, complex disasters and globalization have, for long time, been associated with significant migrations from areas “unsecure” to those assumed to be more secure. Migrants usually bring in host countries their specific problems including health-related. Underutilization of dental health services (DHS) is an example among many others. Most immigrants seek curative than preventive care services. Barriers to dental services utilization, as reported by most immigrants, include low income, lack of dental insurance, older age, male sex and acculturation. Healthcare policymakers of host countries have to urgently and appropriately tackle this unfavourable disparity in healthcare which has a non-negligible burden.
Key words: Dental health services; utilization; migrants.

Abstract
The aim of this study was to assess the effect of various environmental factors on the preservation of pulp tissue in primary teeth as a source of DNA and its use for sex determination using polymerase chain reaction (PCR). 120 samples were grouped into 4 groups of 30 teeth each. Group I samples were kept immersed in a bucket of drainage water, group II, III and IV samples were buried in sand taken from seashore, burial ground and desert, respectively for a period of 2 months. Pulp tissue was collected from each sample and DNA was isolated. PCR amplification was performed and sex determination was done by detection of X and Y chromosome-specific alphoid centromeric repeat sequences. In group I, 86% of the samples exhibited correct gender interpretation by PCR amplification. In groups II, III, and IV, all the samples showed correct results indicating a significant difference in scores between group I and the remaining three groups. Teeth stored in dry conditions can serve as a better source of DNA as compared to the teeth stored in moist conditions and co-amplification of both X and Y specific sequences by PCR is a fast, specific, sensitive and reliable method providing sex determination
Key words: DNA, gender, polymerase chain reaction (PCR), forensics

Abstract
The caries inhibitory effect of extract from tea which is one of the most popular beverages consumed has been studied both in vitro and in vivo. The exact mechanism by which tea can prevent dental caries is yet not known, but certain theories like bactericidal effects of tea against Streptococcus mutans and prevention of bacterial adherence to teeth have been suggested. The present article describes a brief review on some of the research conducted on the caries inhibitory effect of tea.
Key words: Dental caries, tea, anticariogenic.
