AIM:To investigate the associations between CDH1 gene polymorphisms and gastric cancer(GC) risk ***:We analyzed four CDH1 polymorphisms(+54 T>C,-160 C>A,-616 G>C,-3159 T>C) in an Omani population,by extraction of genomic DNA from the peripheral blood of 192 patients with GC and 170 control participants and performed CDH1 genotyping using DNA ***:CDH1-160-AA genotype was associated with an increased risk of GC(OR = 3.6,95% CI:1.1-11.8)(P = 0.03).There was no significant association between the other polymorphisms and GC *** haplotype analysis of +54 T>C,-160 C>A,-616 G>C,-3159 T>C genotypes revealed that the OR of CCGC and CAGC haplotypes was 1.5(95% CI:0.7-3.5) and 1.5(95% CI:0.2-3.0),but did not reach statistical ***:The current study suggests that the-160 AA genotype was associated with an increased risk of GC in Oman.

Introduction: Amelogenesisimperfecta (AI) is a developmental disturbance, genomic in origin, which interferes with normal enamel formation of both primary and permanent dentitions in the absence of a systemic disorder. Three major categories can be recognized clinically, namely hypoplastic, hypomaturation and hypocalcified. Timely and comprehensive intervention is critical to spare the patient from psychological consequences of these disfiguring conditions. Clinical Report: A 10-year-old boy was presented with dissatisfaction with appearance of his teeth sensitivity and poor masticatory efficiency. His medical history was noncontributory. Composite restorative material was selected as a suitable replacement of the defective structures because of its esthetics and high sustainability. Treatment Objectives: The multidisciplinary approach was oriented toward achieving functional and esthetic rehabilitation of these teeth with minimal chair-side time. Treatment Outcomes: The use of composite restorative material resulted in successful and satisfactory enhancement of the patient’s esthetic appearance, as well as protection against further wear and sensitivity thereby improving his functional demands. The longevity of the treatment outcome required meticulous maintenance of oral hygiene and patient compliance. Conclusion: Management of a patient with AI is a challenge for the clinician. Treatment options vary considerably depending on several factors such as age of the patient, socioeconomic status, severity of the disorder, and most importantly, the patient’s cooperation. Composite restorative material is considered an excellent conservative transitional treatment for protection of AI weakened teeth.
