although the delayed exfoliation of primary teeth among children is a common dental problem, simultaneous presence of primary teeth and corresponding successors is a rare feature in adults. this paper reports an unusual case in which both permanent teeth (molars, premolars, and canines) and primary teeth were present simultaneously. this report describes questions concerning the etiology of ove...

dentinogenesis imperfecta (di) is a hereditary dentin defect caused by an autosomal dominant mutation in dentin sialophosphoprotein gene. defective dentin development results in discolored teeth that are prone to wear and fracture. early diagnosis and proper treatment are necessary to achieve better functional and esthetic results and minimize nutritional deficiencies and psychosocial distress....

The incidence of posterior crossbite in the primary dentition has been reported as 8-22%. The crossbite usually results from bilateral maxillary constriction and is commonly associated with an occlusion guided lateral deviation of the mandible upon closing. Correction of the posteriorcross bite in the primary dentition is indicated to establish a stable occlusion and avoid possible deleterious ...

Odontogenic anomalies can occur as a result of conjoining or twinning defects. These include fusion, gemination and concrescence. This article presents two case reports of double teeth. In the first case reported, a 4 -year-old white boy presented primary double teeth associated to the absence of the right permanent mandibular lateral incisor. In the second case, a 5-year-old white girl had a f...

The periodontal ligament has a rich sensory nerve supply which originates from the trigeminal ganglion and trigeminal mesencephalic nucleus. Although various types of mechanoreceptors have been reported in the periodontal ligament, the Ruffini ending is an essential one. It is unknown whether the distribution of periodontal nerve fibers in deciduous teeth is identical to that in permanent teeth...

The correlation between caries prevalence in the primary dentition at age 7 and the permanent dentition at age 13 was examined in 136 ctu’Idren. The caries increment in the permanent dentition from age 7 to 13 years was also examined. A correlation coefficient of 0.47 in 79 males and 0.61 in 57females (p<O.O01) was found between the deft age 7 and the DMFS at age 13. A significant difference in...

To investigate the commonly affected carious teeth in the early and late mixed dentition period of male and female orthodontic patients. A total of 224 (Male: Female ratio 118: 106) patients were diagnosed in the early mixed and late mixed dentition in 3 age subgroups; 6-7 years, 8-10 years and 11-13 years at the patients were investigated regarding carious lesions in the maxillary and mandibul...
