The prevalence of dental anomalies in cleft lip and/or palate patients was higher than what had been reported in the normal Jordanian population. This emphasizes the relation of cleft lip and/or palate to all dental anomalies studied. Although our study represents a thorough and complete description of dental anomalies present in a sample of cleft lip and/or palate subjects, larger samples are required to effectively determine the relationship of each dental anomaly with cleft type.

Osteoporosis was significantly associated with severe alveolar crestal bone loss and the prevalence of periodontitis cases in postmenopausal Jordanian women.

Bilateral cleft lip and palate patients appear to be at a higher risk of caries experience and poorer in oral hygiene than those with UCLP patients. These findings not only provide a baseline for oral health parameters in patients with cleft lip and palate but also emphasize the need for intensive preventive measures of oral disease to optimize clinical outcome.

Objective: The aim of this study was to evaluate the topographic relationship between the inferior dental canals (IDCs) and the roots of impacted mandibular third molars. Methods:Preoperative orthopantomograms (OPGs) were examined and the proximity of the IDC to the roots of impacted mandibular third molars was categorized into the following: groups: superimposition, adjacent, perforation, grooving, notching, or none. The categories notching, grooving, and perforation were regrouped together and called the true relationship between the IDC and the root apices. The type of impaction, age, and sex of the patient were also noted. Results:The positional category of 96.1% of the radiographs with bilateral impactions was identical on both sides of the mandible. Out of 2526 impacted mandibular third molars examined, 1146 (45.3%) belonged to the superimposition category, 663 (26.2%) were adjacent, 312 (12.3%) showed grooving, 78 (3.08%) showed notching, and 9 (0.35%) were actually perforating the IDC. The results showed 15.7% of the total cases were in true relationship with the IDC. There was a significant association (p = 0.000) between patient's age and true relationship. Conclusions:Identical positional relationship of the bilateral impacted third molars to the IDC was noted in 96.1% of the radiographs. The position of the IDC in relation to the roots of impacted third molars varied according to the patient's age.

While thalassaemia major may not be associated with the occurrence of either vascular canals or prominent antegonial notch, spiky-shaped and short roots, taurodonts, attenuated lamina dura, enlarged bone marrow spaces, small maxillary sinuses, absence of inferior alveolar canal and thin cortex of the mandible were found to be reliable diagnostic criteria for thalassaemia major.
