Sažetak

Objective: To provide odontometric information in three dimensions; Mesiodistal, Buccolingual and Clinical Crown Height in the primary dentition of Nigerian children. Materials and Method: A sample of healthy 400 nursery school children aged 3-5 years old with fully erupted primary teeth were randomly selected from six public nursery Schools. Dental stone models were made from maxillary and mandibular alginate impressions of the population sample. Mesiodistal (MD), Buccolingual (BL) and Clinical Crown Height (CCH) measurements of teeth were done using electronic digital caliper. The descriptive statistics were obtained for all parameters using SPSS version 13. Result: A total of 8,000 teeth were measured. The mean MD and BL tooth crown dimensions increased progressively from the lateral incisors to the second primary molars in the maxillary arch while the dimensions increased from the central incisors to the second primary molars. The largest mean MD dimension was the mandibular primary second molar with 10.20mm+ 0.56, the maxillary second molar had the largest mean BL dimension of 9.74mm+0.58, while the mandibular canine had the largest mean CCH dimension of 5.83mm+0.61. The males had larger mean tooth dimensions in most tooth types. There were statistically significant differences between the tooth dimensions in both genders (p<0.05) and variations within tooth classes. Conclusion: It can be concluded that Nigerians have larger primary tooth dimensions than Caucasians, Jordanians, Taiwanese and smaller primary tooth dimensions than Australian Aborigines but comparable to those of Indians.
