“…The prevalence of tooth agenesis among cleft patients is significantly higher (45-77%; 1, 6) than among noncleft patients (3.2-7.6%; 13). One reason for this may lie in specific surgical procedures, such as periosteoplasty or neonatal closure (14).…”

Orofacial clefts are a common oral disorder associated with tooth agenesis. As information on the simultaneous absence of teeth can be an aid in treatment planning, a large sample of orofacial cleft patients was examined. The sample consisted of 910 patients with cleft lip and palate. Tooth agenesis was assessed on the basis of at least two panoramic radiographs and patient records. Third-molar agenesis was determined in 474 patients. Patterns of tooth agenesis were analysed using Tooth Agenesis Code (TAC) values, according to VAN WIJK & TAN. Per quadrant, at least 90% of patients could be described according to three different patterns. In the maxilla, 85% of patients with tooth agenesis had a TAC-value of 2, 16, or 18 on either the left side, right side or bilaterally. In the mandible, 90% of patients with tooth agenesis had a TAC-value of 16, 1 or 2 on either the left side, right side or bilaterally. In patients with tooth agenesis, patterns were symmetrical in the maxilla in 18.8% and in the mandible in 51%. More extended cleft types were associated with a higher prevalence of tooth agenesis. Third-molar agenesis (prevalence = 22.4%) was significantly related to the prevalence of other absent teeth. These results show which patterns of tooth agenesis can be expected to occur in most orofacial cleft patients.

“…Three main factors might contribute to the increased prevalence of tooth agenesis in the BCLP patients. First, it has been hypothesized that specific surgical procedures, such as early periosteoplasty (21) or neonatal closure of the hard palate (22,23), might influence tooth formation because a lower prevalence of tooth agenesis was found in non-operated individuals with clefts (24). However, other studies have reported that surgical interventions do not seem to affect tooth agenesis (17).…”

Individuals with cleft lip and palate present significantly more dental anomalies, even outside the cleft area, than do individuals without clefts. Our aim was to evaluate the prevalence of tooth agenesis and patterns of hypodontia in a large sample of patients with complete bilateral cleft lip and palate (BCLP). Serial panoramic radiographs (the first radiograph was taken at 10.5-13.5 yr of age) of 240 patients with BCLP (172 male patients, 68 female patients) were examined. Third molars were not included in the evaluation. Agenesis of at least one tooth was present in 59.8% of patients. Upper laterals and upper and lower second premolars were missing most frequently. Using the tooth agenesis code (TAC), 52 different agenesis patterns were identified, of which simultaneous agenesis of 12, 22, 15, 25, 35, and 45 was the most frequent pattern. Nine of the 240 patients showed combined BCLP and oligodontia.

Lekkas и соавт., проанализировав состояние зубочелюстной системы у 266 взрослых с неоперированными РГН, обнаружили у них исключительно низкий процент аплазии зубов и высказали предположение о влиянии на формирование зачатков зубов травматичной пластики неба в раннем возрасте [8]. В нашем исследовании из 35 детей с дефектом неба после уранопластики выраженная гипоплазия эмали постоянных резцов была обнаружена у 13 (37,1±7,4%), аплазия боковых резцов -у 18 (51,4±8,4%), аплазия центральных резцов -у 5 детей (14,3±5,9%).…”

The aim of the study was to assess the significance of environmental risk factors for teeth aplasia and hypoplasia in cleft lip and palate children. Two hundred and forty-seven cleft lip and palate (CLP) children were enrolled in the study including 105 (42.5%) with bilateral CLP and 57.5% with unilateral CLP. The mean age was 11.2±4.9 years. Teeth condition was assessed clinically and radiologically. The impact of risk factors for teeth anomalies was analyzed by retrospective data obtained from computer database (absence of preoperative orthopedic treatment, palatal defects after primary palatoplasty and type of primary procedures). Surgical trauma by early periosteoplasty (at the age of 3-4 months), excessive scarring and tissue traction due to absence of early orthopedic treatment and palatal defect were associated with significantly higher incidence of incisors hypoplasia (both developmental enamel defects and microdentia) and aplasia of central incisors not seen in the other study subgroups. Incisors aplasia and hypoplasia in CLP patients do not always have disembryogenic origin but may depend on external environmental factors, including surgical trauma.
