Aims To provide information regarding the different types of soft drinks and critically reviewing their risk on the dental and general health of children and adolescents, as well as the cost associated with such drinks. Methods The literature was reviewed using electronic databases, Medline, Embase, Cochrane library, and was complemented by cross-referencing using published references list from reviewed articles. Search words; soft drinks, juices, carbonated drinks, sports and energy drinks, soft drink and dental diseases, soft drink and health, cost of soft drinks, soft drink advertising, sugar tax on soft drinks were used for this review. In total, 104 papers were reviewed by both authors; of these, 62 papers were found to have relevant information. Results The consumption of soft drinks was found to have increased dramatically over the past several decades. The greatest increase in soft drink consumption has been among children and adolescents. Some commercial soft drinks are high in sugar content and acidity. In addition, they supply energy only and are of little nutritional benefit and lack micro-nutrients, vitamins and minerals. Soft drink consumption can contribute to detrimental oral and general health. Efforts have been made by manufacturers and government agencies to reduce the potential harmful effects of sugar-containing soft drinks on teeth and general health. These include banning the sale of soft drinks in schools, restricting soft drinks advertising, modifying the composition of soft drinks and introducing tax on sugar-containing soft drinks. Conclusions The consumption of soft drinks with high sugar content and acidity can contribute to detrimental oral health and may also affect general health. Therefore, it is necessary to educate patients about the harmful effects of different types of soft drinks as it is not always easy for individuals to identify from drink labelling the ingredients which they contain.

Dental caries was associated with negative impacts on children and parents' quality of life. Treatment of caries improved the quality of life of children and families significantly, irrespective of whether the treatment was provided by a conventional or a biological approach.

Despite the higher reported sensitivity and specificity of laser Doppler flowmetry in assessing pulp blood flow, these data are based on studies with a high level of bias and serious shortfalls in study designs. More research is needed to study the effect of different laser Doppler flowmetry's parameters on its diagnostic accuracy and the true cut-off ratios over which a tooth could be diagnosed as having a normal pulp.

Background In the last few years, conventional restorations including complete removal of carious tissue (CT) with or without pulp therapy for the treatment of carious lesions (CL) in primary teeth have been challenged and a more biological approach has been suggested. This approach involves the use of less invasive techniques which alter the environment of the CL isolating it from the cariogenic biofilm and substrate. Two of these treatment approaches that are becoming increasingly widely accepted and used in paediatric dentistry are the Hall Technique and indirect pulp capping (IPC). Aim To investigate the outcome of the conventional versus the biological approaches for the treatment of deep CL in the primary teeth in children, delivered in a specialist paediatric dentistry training environment. Design This was a retrospective cohort study of 246 children aged 4–9 years, treated with either approach, conventional and biological, in two UK specialist hospital settings. Data were extracted from clinical dental records and post‐operative radiographs of patients treated during the period 2006–2012. The outcome of the treatment in this study was categorised into three main categories: clinical, radiographic, and final outcome. Clinical and final outcomes were further described as success, minor, and major failure. Results In total, 836 primary teeth were included. In the conventional approach, 324 teeth had complete CT removal and 104 teeth had a pulpotomy. In the biological approach, 388 teeth had Hall Technique preformed metal crowns (PMC) placed and 20 teeth received indirect pulp capping. PMC were the restoration of choice for most of the cases where a pulpotomy had been carried out, and resin composite was most frequently used restorative material for the complete CT removal group. The majority of the primary teeth treated with either approach remained asymptomatic after a follow‐up period of up to 77 months, 95.3% in the conventional and 95.8% in the biological. No significant association was found between the final outcome and the approach used for treatment, age of the patient, gender and number of carious surfaces or tooth type. Conclusion Both the conventional and biological treatment approaches had similar final outcomes and were equally successful for management of CL in the primary dentition.
