Topic: Impact Of Maternal, Perinatal And Postnatal And Epigenetic Factors On Early Childhood Caries And Eruption Timing Of Primary Teeth In Nigeria


There is a high prevalence of early childhood caries (ECC) among Nigerian children. Occurrence of dental caries in children has been associated with increased missed school time and declines in school performance with reduction in quality of life. Ethnicity, geographical and sex-related differences in the timing of primary tooth eruption and ECC occurrence have been reported, but how factors such as socioeconomic status, nutritional status, maternal education and health are associated with ECC need to be investigated. Little attention has been given to identify maternal, after-birth and epigenetic risk indicators for ECC development in Nigerian children. This study aims to examine the interrelationship of number of teeth at ages one and two years with pregnancy and postnatal factors, determine whether certain maternal, perinatal and postnatal factors could be important risk indicators for the development of early childhood caries in Nigerian children, explore any association between the eruption timing of primary teeth and the development of subsequent dental caries, and identify genetic and epigenetic markers associated with deciduous tooth eruption timing and dental caries. Therefore, novel methods of caries prevention and lifestyle-related policies based on research-based evidence of association of caries markers and groups of risk factors can produce a personalized approach in the control of this disease resulting in poverty reduction and cost savings for our Nation’s health sector.

Current Research

Evaluation of spatter and aerosol reduction effectiveness of four dry-field isolation techniques: A Benchtop Procedure

Research Details

Dentists routinely perform procedures in the oral cavity. Aerosol and spatter production can be generated during dental procedures in the oral cavity such as hard-tissue preparation with a high-speed dental handpiece or use of an ultrasonic scaler. This aerosol and spatter might contain infectious agents originating from the patient or the dental unit waterlines that pose a health threat to the dentist, patient and staff members. This study aims to investigate the aerosol and spatter mitigation quality of 4 dry-field isolation methods in a simulated setup that replicates real-life work scenarios encountered in dental practices. 

Methods: All-ceramic crown preparation on tooth 28 and 30 using a diamond bur with a high-speed air-turbine for 60s and use of 3-in-1 air and water spray to wash mesial-occlusal cavity in tooth 29 was repeated six times for each setup to simulate a patient under care. Environmental, body and operator face shield spatter, aerosol and sound intensity were measured. Analysis of variance was used, and posthoc pairwise comparisons performed to compare least-squares means when appropriate using a Tukey adjustment. 

This study brings to light the most successful techniques that can be incorporated into the dental practice to mitigate spatter and aerosols from aerosol generating procedures. Many different mitigation strategies and devices have been created and advertised to address the concerns of the creation of aerosol and spatter during dental procedures. This paper attempts to demonstrate potential effective mitigation strategies that can be employed while the dentist actually works in the oral cavity.
