Dentigerous cyst is the most commonly occurring odontogenic cyst after radicular cyst and accounts for 15% of all true cysts in the jaws. The cyst is more common in mandible than in maxilla. The dentigerous cyst is commonly associated with impacted mandibular third molars. In maxilla, the incidence is rare. Dentigerous cyst in maxillary sinus in association with an impacted third molar is an uncommon entity. We present a case of dentigerous cyst associated with an impacted third molar, completely obliterating the maxillary sinus in a 28-year-old female.

Purpose -Inventory control models for perishable products have primarily used a FIFO issuing policy with the objective of minimizing the number of outdated units. This paper aims to develop a model to evaluate an issuing policy for a single product with a fixed shelf life in single echelon inventory system. The issuing policy considers the remaining shelf life of the in-stock inventory and the expected time that the product will spend in inventory as the decision driver. Design/methodology/approach -The model developed has an objective of maximizing expected revenue over time with a budget constraint. A heuristic algorithm is proposed to iteratively arrive at the best solution to the formulation. The heuristic is tested by employing a simulation model of the system. Findings -The proposed heuristic is tested against both the FIFO and the random allocation approaches and found to be superior for all the in-stock with remaining shelf life distribution means of above 40 percent. No significant performance differences were found for the three approaches for remaining shelf life distribution.Research limitations/implications -The research is focused on a single product with multiple expiration dates and further research is necessary to determine the best policies for the multi-product multi-expiration date environment where the items are substitutable.. Practical implications -Retailers stock items with multiple expiration dates. The customer, for obvious reasons, is more likely to choose the item with the longer remaining shelf life. Therefore, the supply to the retailer's shelves and issuing policies for making available the particular items to the customers affect product outdating and related costs. Revenues will be affected by the extent to which more can be charged for items with a longer remaining shelf life or by the impact of the remaining shelf life on demand. This paper provides for a practical approach to that end. Originality/value -The proposed issuing policy has not been tested before and thus makes a contribution to the body of knowledge. The flexibility of using different values for acquisition costs, selling prices, salvage value and penalty functions is a particular strength of the proposed model. Moreover, its potential application to inventory control problems for a wide range of perishable products is substantial.

Aim: The aim of the study was the identification of predictors of psychology and beliefs among parents of children affected by cleft lip and cleft palate. Methods: The study included a sample of 157 parents of children having cleft lips and cleft palates. Parents were given a questionnaire related to their beliefs and reasons behind deformity. Results: Out of 157 participants, 90 were fathers, and 67 were mothers. The children with deformities included 105 boys and 52 girls. The majority of parents (43) believed that the eclipse was one of the reasons for the deformity and the other was God’s wrath for the mother’s sins. The time of birth was considered a factor for cleft lip and palate by 27 parents. The study revealed that the self-esteem of fathers was higher than mothers and they were more concerned of being undesirably judged by others due to deformity of their children than the mothers. Conclusion: It can be inferred that the parents of a child with cleft lip and palate differ in their psychosocial adjustments. Also, mothers experience more psychosocial problems than fathers. The superstitious beliefs still prevail in rural areas despite advanced medical facilities and awareness.
