Abstract

The rising demand for dental implants necessitates addressing anatomical challenges, particularly the shape of the mandible. Incorrectly angling implants can cause lingual perforations, risking damage to the inferior alveolar artery and nerve. This study analyzed 96 cone-beam computed tomography images from individuals aged 20 to 70 (8 males and 8 females) to evaluate mandibular anatomy in four areas: left and right sides and the first and second molars. Mandibular shapes were classified into U, C, and P types. U-shaped mandibles, with a wider crest width, pose the highest risk of lingual perforation. Measurements for U-shaped types included concavity angle, length, and depth. Statistical analyses (T-tests and ANOVA) with a 95% confidence interval showed no significant differences between the left and right sides. However, significant differences based on gender, age, and tooth type were found. The study found U-shapes in 34.6% of cases, P-shapes in 28.9%, and C-shapes in 36.5%, with U-shapes more common in second molars. Understanding these variations enhances the safety and effectiveness of implant procedures and oral surgeries. [ABSTRACT FROM AUTHOR]

Abstract

The purpose of this study was to evaluate the association between asthma and benign prostatic hyperplasia (BPH) in an adult Korean population and to evaluate this association based on the treatment status of asthmatics. We utilized the Korean genome and epidemiology study health examinee 2004 to 2016 database. A total of 47,186 participants (825 asthmatics and 46,361 controls) were selected and their BPH histories were analyzed. We categorized the participants according to their asthma treatment status: “well controlled”; “being treated”; and “not being treated”. The adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for BPH were analyzed using multiple logistic regression. Subgroup analyses were performed according to age (60 years). The results showed that the prevalence of BPH was higher among asthma patients (17.1%) than among controls (8.7%, P 60 years and 2.24 (95% CI = 1.70–2.96) in those aged ≤60 years. The ORs for BPH were 1.82 (95% CI = 1.16–2.87, P = .009) in the “well-controlled” group, 1.05 (95% CI = 0.74–1.49, P = .794) in the “being treated” group, and 2.24 (95% CI = 1.69–2.97, P
