Wadhawan et al. (2015) suggested that Pica is likely to cause effect on teeth. Chewing on stones and bricks can lead to attrition of teeth. Damage to teeth and gingiva occurs due to chewing from abrasive materials such as twigs or metals. On reviewing literature, many cases reporting ill effects of pica on dentition have been published. An unusual case report was reported by Djemal et al. (1998, case report on tooth wear associated with an unusual habit). Handiso (2015) suggests the prevalence of food aversion( 67% ), food craving ( 43.5%) and pica practicing behaviour ( 30.4%). This study revealed that pica practicing is significantly associated with poor nutritional status of pregnant women. Based on the results of this study, an intervention is needed to decrease the prevalence of food aversion, food craving and pica during pregnancy. Alternative foods should be advised for pregnant mother who are practicing food aversion. Call et al. (2015) describes Pica as a potentially deadly form of self injurious behaviour most frequently exhibited by individuals with developmental and intellectual disabilities. This study quantifies the overall effect size of behavioural treatment of pica by examining treatment data from all patients seen for treatment of pica at an intensive day treatment clinical …show more content…
(2010) defines pica as an unsual condition where patients develop cravings for non nutritive substances that can cause significant health risks. This study reports three patients with pica, two of them showing evolutionary changes associated with pica and that third demonstrating a peculiar nature of pica, which has yet to be reported. All three patients presented with hematological parameters diagnostic for iron deficiency anaemia. These researchers believe pica is an important sign of iron deficiency that should never be ignored, and the craving for any unusual substance should compel clinicians to search for occult blood loss with secondary iron
