However, dried fruits such as raisins and fresh fruit such as apples and bananas disappear from the mouth quickly, and do not appear to be a risk factor. Consumers are not good at guessing which foods stick around in the mouth.For children, the American Dental Association and the European Academy of Paediatric Dentistry recommend limiting the frequency of consumption of drinks with sugar, and not giving baby bottles to infants during sleep (see earlier discussion). Parents are also recommended to avoid sharing utensils and cups with their infants to prevent transferring bacteria from the parents mouth.Xylitol is a naturally occurring sugar alcohol that is used in different products as an alternative to sucrose (table sugar). As of 2015 the evidence concerning the use of xylitol in chewing gum was insufficient to determine if it is effective at preventing caries. Other measures
The use of dental sealants is a means of prevention. A sealant is a thin plastic-like coating applied to the chewing surfaces of the molars to prevent food from being trapped inside pits and fissures. This deprives resident plaque bacteria of carbohydrate, preventing the formation of pit and fissure caries. Sealants are usually applied on the teeth of children, as soon as the teeth erupt but adults are receiving them if not previously performed. Sealants can wear out and fail to prevent access of food and plaque bacteria inside pits and fissures and need to be replaced so they must be checked regularly by dental professionals.
Chronic actinic dermatitis is a condition where a subjects skin becomes inflamed due to a reaction to sunlight or artificial light. Patients often have other related conditions of the skin that cause dermatitis in response to a variety of stimuli (e.g., flowers, sunscreens, cosmetics, etc.). Symptoms
Once affected, the symptoms may not show for several days. The symptoms can be severe burning, itching, swelling and pain in the affected areas. The areas exposed to sunlight may have the appearance of a sunburn - where clothing is worn the skin is protected. There is no known reaction to moonlight, but reflections from windows and mirrors of sunlight can still cause damage. Diagnosis
Diagnosis can occur at any age, ranging from soon after birth to adulthood. A GP may refer a patient to a dermatologist if the condition is not showing clear symptoms, and a variety of tests - usually completed at a hospital - can then determine the exact nature and cause of the patients condition. Reactions, which vary depending on the severity of the case, include rashes, flared bumpy patches, affected areas being extremely hot to touch, and outbreaks shortly (or within 24 hours) after direct or indirect exposure to UVA and/or UVB light. The skin most likely reacts on the upper chest, hands and face, however it is not unlikely for reactions to happen all over the body. The patient may feel burning, stinging or throbbing sensations in these areas, which causes mild, yet uncomfortable pain in some patients.
