RESUMEN
No other factor plays a more significant role in preventive and interceptive dentistry than the preservation of deciduous dentition till its normal time of exfoliation. Premature loss of a deciduous tooth or a group of teeth might lead to wide range of implications. When the deciduous second molar is lost before the eruption of first permanent molar, intra-alveolar type of space maintainer is indicated. But in cases of bilateral loss of these teeth the conventional design generally poses a variety of problems. Thus, the conventional designs are required to be modified according to the needs of the patient. Therefore, this paper describes an entirely new design of the Willet's appliance in cases of bilateral loss of deciduous molars before the eruption of first permanent molar.

An in vivo study comparing the different methods of caries removal was done in children of age group 6-9 years. Among these patients a total number of 150 carious deciduous teeth were selected. Caries removal was done by hand instruments, airotor and carisolv. The efficacy, time taken and pain experienced by the patient during caries removal was evaluated. The results showed that airotor was the most efficient method (mean value 0.38), while carisolv was the least painful (mean value 0.080) and the most time consuming method (534.8 seconds).

Dental caries, a multifactorial disease requires four principle factor: the host, the microflora, the substrate & time for its occurrence and can be prevented or managed by elimination/modification of either of the above factors. The conventional preventive measure being followed for long time for the dental caries are not successful to the desirable extent due to their non avaibailaballity in the rural areas, lack of awareness & inaccessibility of dental services. Therefore, the focus has now been shifted to submicroscopic level to ensure that these measures can be reached to the farthest areas & each & every member of the population is benefitted. Few of the measures taken are. i) Genetically modifying the S. Mutans: ii) Searching The antagonist peptides to work against the specific enzyme system (Glucosyltransferase) of S. Mutans. iii) Changing the oral environment by those Genetically modified organisms that will produce bases (instead of acids) & these bases provides a milieu favoring remineralization. This paper discusses various ways in which genetically modified strains of microogranisms or genetically modified strains of microogranisms of genetically modified foods can help in the prevention of caries.
