“…If exposure to irradiation occurs before calcification, the tooth bud may be destroyed. Radiation at a later stage of development may arrest further growth and result in irregularities in enamel and dentin together with shortened roots (Scheibe et al, 1980;Dahllöf et al, 1994b;Kaste et al, 1994). According to Scheibe et al (1980), tooth eruption is mostly delayed but not hindered, but this phenomenon still needs further study.…”

In addition to anti-tumor effects, ionizing radiation causes damage in normal tissues located in the radiation portals. Oral complications of radiotherapy in the head and neck region are the result of the deleterious effects of radiation on, e.g., salivary glands, oral mucosa, bone, dentition, masticatory musculature, and temporomandibular joints. The clinical consequences of radiotherapy include mucositis, hyposalivation, taste loss, osteoradionecrosis, radiation caries, and trismus. Mucositis and taste loss are reversible consequences that usually subside early post-irradiation, while hyposalivation is normally irreversible. Furthermore, the risk of developing radiation caries and osteoradionecrosis is a life-long threat. All these consequences form a heavy burden for the patients and have a tremendous impact on their quality of life during and after radiotherapy. In this review, the radiation-induced changes in healthy oral tissues and the resulting clinical consequences are discussed.

“…It might be the result of either environmental or genetic factors, or a combination of these. [13][14][15][16][17][18][19][20][21][22][23][24][25] One of the determinants of successful orthodontic treatment with perfect occlusion is harmonious tooth size. Tooth size in relation to the mandibular and maxillary arches determines whether the dentition is spaced or crowded, and discrepancies in the sizes of teeth in different arches determine buccal interdigitation, overjet, overbite, and center line discrepancies.…”

Objective: To evaluate and compare the sizes of teeth in mild and severe hypodontia patients with those of healthy controls. Materials and Methods: Dental casts of 154 patients with two or more congenitally missing teeth were obtained. Patients were divided into two groups according to severity of hypodontia. Group I (mild) consisted of 118 patients with two to five missing teeth. Group II (severe) consisted of 36 patients with six or more missing teeth. In addition, a control group was included, which consisted of 50 patients who had an Angle Class I jaw relationship and no missing teeth. Mesiodistal and labiolingual dimensions of the teeth were measured with a digital caliper on dental casts. The independent-samples t-test was used to evaluate the effect of gender on measurements. Intergroup differences for mesiodistal and labiolingual dimensions were evaluated with analysis of variance and post hoc Tukey tests. Results: Statistically significant differences were found between girls and boys with hypodontia in the mesiodistal dimension of the mandibular first premolar and the labiolingual dimension of the mandibular lateral incisor (P , .01). Mesiodistal and labiolingual width measurements of the teeth of hypodontia patients showed statistically significant differences compared with the control group (P , .05). Most teeth showed significant dimensional reductions in severe hypodontia compared with mild hypodontia (P , .05). Conclusions: The mesiodistal and labiolingual dimensions of teeth in both mild and severe hypodontia groups were smaller than those in control subjects. The reduction in size was more excessive in the severe hypodontia group. The teeth showing the greatest difference in tooth dimensions were the maxillary lateral incisor (in mesiodistal dimension) and the mandibular canine (labiolingual dimension).

“…Aggressive treatment regimens may have a dramatic impact on the health and quality of life of long-term survivors of cancer [1][2][3][4][5][6][7][8][9][10]. In addition, late adverse effects of therapy are becoming increasingly prevalent due to improved survival rates among infants and children; these treatment-associated sequelae include dental abnormalities.…”
