Occlusal Standards in Temporary Dentition: A Survey of an Infantile Population in Fez, Morocco

Achabi Najoua*

Objective: Until these days, the occlusal standards characterizing the Moroccan child population have not been evaluated. Only international references are used. The objective of this work is to place the occlusal standards of our population in relation to international references, by comparing the intra and inter arch parameters found in our study (arch perimeter, inter canine distance, inter molar distance) with those found in other similar studies.

Methodology: A sample of 30 children (17 girls, 13 boys), aged from 3 to 5 years, was selected from the nurseries of the city of Fez. Study casts were made. Measurable data were collected and analyzed by SPSS 13.0 software (Chicago, IL, USA).

Results: The majority of the children examined had different types of diastema. Their prevalence was (96.7%) in the maxilla and (66.66%) in the mandible, with a predominance in males. The length, perimeter, and width of the arch in the children of our sample are of an average value that is close to the other populations, but it was difficult to compare all the results; due to the use of different measurement techniques by the investigators. A similar terminal plane and canine ratio were found in most children in our survey. Incisal overlap and overhang had successive average values of 1.10 mm and 1.20 mm.

Conclusion: Our study will be a key for Moroccan investigators in different regions of the country to be able to determine the characteristic occlusal standards of our country and to be able to compare them with those of similar studies.
