“…Multiple PPT and unerupted permanent teeth are usually associated with syndromes (Cleidocranial dysplasia, Gardner syndrome, Zimmerman Laband syndrome, Noonan's syndrome, Hyper-IgE syndrome) and conditions such as hemifacial atrophy, hypopituitarism, hypothyroidism, cherubism, gingival fibromatosis and cleft palate [27,28]. Case reports of systemically healthy patients with multiple PPT have also been reported [22,29]. In this present study, 80 healthy children with two or more PPT were selected and matched with children without PPT.…”

Background: Persistent primary teeth (PPT) may occur due to various local factors, or it may develop due to general factors such as systemic diseases and syndromes. Since eruption and dental development are two different processes, it is important to investigate both processes to determine the actual cause of delayed tooth eruption. The study aimed to evaluate the dental development of a group of Turkish children with multiple PPT using the Willems dental age estimation method. Study Design: Digital panoramic radiographs of children and adolescents aged between 9 and 15 years were retrieved, assessed and categorized. A total of 80 radiographs of patients with more than one PPT were selected and matched with children without PPT. Dental age was calculated using the method of Willems et al. All analyses were conducted using the SPSS statistical software. The statistical significance was set at 0.05. Results: The permanent tooth development of children with multiple PPT could be delayed by 0.5–4 years compared to healthy ones. A strong positive correlation was found between the number of PPT and deviation for both females and males (p < 0.001). Conclusion: In conclusion, we found that permanent tooth development of children with multiple PPT could be delayed compared to healthy ones. In addition, as the number of PPT increased, the difference between chronological age and dental age also increased, especially in males.

“…Although delayed eruption is commonly associated with PPT, it can also occur in the absence of PPT. The occurrence of PPT is considered a consequence rather than a cause of delayed eruption [9,22]. On the other hand, a strong correlation was reported between eruption time and dental maturity [23].…”

Background: Dental pathologies are noticeable alterations or deviations from normal dental architecture and can be influenced by genetic or environmental factors. This present study aimed to identify and report the dental pathologies in the Nigerian local pig. Materials and methods: The cleaned skulls of 47 local pigs, aged between 3-51 months were assessed for observable dental abnormalities such as missing teeth, fractured teeth, persistent deciduous teeth, dental caries, dental calculus, and tooth rotation. Results: The study revealed that 98% of the skulls had dental attrition while 96% had stained teeth. About 66% had a least a missing tooth while 78% of adult skulls had at least one persistent deciduous tooth. Fractured tooth, dental calculus, dental caries, and tooth rotation were observed in 46.8%, 74.4%, 34% and 21.3%, respectively. The most common persistent deciduous tooth was the second maxillary incisor, whereas the most commonly missed tooth was the first mandibular premolar, which was bilateral in 75% of affected skulls. Dental calculus was not observed on skulls below 6 months, while the incisor tooth was the most affected tooth by dental attrition. Conclusions: The Nigerian local pig, like other breeds, is susceptible to and has dental pathologies. The data obtained from this study will be beneficial to farmers, as early detection of dental abnormalities will promote productivity and reduces economic losses in pig husbandry. It will also be useful to researchers, especially those using pigs in Nigeria as a model for translation research and comparative dental studies.
