Radiographic Assessment of Permanent First Molars Among Adults in Riyadh: A Retrospective Study.

Introduction The first permanent molars (FPMs) are the first permanent teeth to emerge in the oral cavity, which have an important role in dentition, dental development, and occlusion. FPMs are the most susceptible teeth to caries due to early eruption. There are many adverse consequences related to losing FPMs. Many of the previous studies focused on younger age groups. To the best of our knowledge, there needs to be more newly updated data reported in the literature regarding the status of FPMs in adults in Saudi Arabia. The study aimed to assess the status of permanent first molars among ad…

The remains of a tomb were discovered below the foundations of the Roman church of “Majka Bozja Gorska” in Lobor in 2002. It was a vaulted t … dard. Dental analysis showed a build-up of tartar on the buccal side, with 5 teeth missing from the dentition post-mortem and a partial lowering and accretion of the alveolar walls of the 2nd molar space secondary to tooth loss. The remains of the person from grave 107 show that the person was approximately 30-35 years of age, confirmed by microscopical ana …

Mesh-assisted regenerated site for alveolar ridge preservation: A case report.

BACKGROUND: The proposed technique utilizes the osteoconductive regenerative properties of bone-substitute materials (BSMs) and the space-maintaining function of titanium mesh to restore the alveolar ridge at extraction sites with lost labial plates in a single procedure. This approach may reduce the need for extensive ridge augmentation procedures, shorten treatment duration, minimize complications, and potentially lower overall costs for patients. METHODS: Both patients presented with hopeless dentition, characterized by chronic infection and loss of the labial plates. To regenerate the alv…

Is periodontal phenotype modification therapy beneficial for patients receiving orthodontic treatment? An American Academy of Periodontology best evidence review.

BACKGROUND: Orthodontic treatment can greatly impact the periodontium, especially in dentitions with a thin periodontal phenotype. Orthodontic tooth movement can result into iatrogenic sequelae to these vulnerable anatomic conditions, such as development and exacerbation of bony dehiscence or fenestration defects, which can manifest loss of periodontal support and gingival recession (GR). This systematic review aimed to investigate whether periodontal phenotype modification therapy (PhMT) involving hard tissue augmentation (PhMT-b) or soft tissue augmentation (PhMT-s) has clinical benefits for…

Evaluation of internal and external hexagon connections in immediately loaded full-arch rehabilitations: A within-person randomised split-mouth controlled trial.

PURPOSE: To evaluate if a different morphology of the implant-abutment connection (internal vs. external hexagon) is able to condition the behaviour of hard and soft peri-implant tissues. MATERIALS AND METHODS: Twenty patients with significantly unfavourable prognoses for their residual maxillary or mandibular dentitions were selected and rehabilitated with immediately loaded fixed full-arch rehabilitations in two different centres. Four to six implants with identical macro- and micro-topography were inserted in each arch: external hexagon implants (EHC) in one randomly selected side of the d…

Tooth loss and cancer risk: a dose-response meta analysis of prospective cohort studies.

Conflicting results to identify the relationship between tooth loss and cancer risk. Therefore, a dose-response meta-analysis was performed to clarify and quantitative assessed the correlation between tooth loss and cancer risk. Up to March 2017, 25 observational epidemiological studies were included in current meta-analysis. Tooth loss was significantly associated with a higher risk of cancer. Additionally, tooth loss was associated with significantly a higher risk of esophageal cancer, gastric cancer, head and neck cancer, colorectal cancer, pancreas cancer, lung cancer, prostate cancer, bla

Qualitative radiographic characteristics of MRONJ-affected bone in oral and parenteral drug administration: comparison of panoramic radiography and cone-beam CT.

BACKGROUND: Our aim was to compare the capacity of panoramic radiography (PR) and cone-beam computed tomography (CBCT) first for the detection of bone affected by medication-related osteonecrosis of the jaw (MRONJ) using qualitative radiographic parameters; and second for the evaluation of the relationship between drug administration route and associated bone changes. METHODS: PR and CBCT images of 24 MRONJ patients using oral or intravenous (IV) bisphosphonates were scored for the detection of osteolysis, osteosclerosis, lamina dura thickening, periodontal ligament widening, persistent extrac

The diagnosis of hypophosphatasia in children as a multidisciplinary effort: an expert opinion.

Hypophosphatasia (HPP) is a rare genetic disorder in which pathogenic variants of the ALPL gene lead to a marked decrease of tissue non-specific alkaline phosphatase (TNSALP) activity. Although HPP is a systemic disorder, its clinical manifestations are more evident on bones, teeth, muscle and central nervous system. The clinical spectrum ranges from severe forms with extreme skeletal deformities, respiratory impairment, seizures, to very mild forms with onset in late adulthood and few clinical signs. The diagnosis can be suspected by measurement of TNSALP activity, but the insufficient awaren

Review of Myeloma Therapies and Their Potential for Oral and Maxillofacial Side Effects.

Myeloma is a common haematological malignancy in which adverse skeletal related events are frequently seen. Over recent years, treatment for myeloma has evolved leading to improved survival. Antiresorptive therapy is an important adjunct therapy to reduce the risk of bone fractures and to improve the quality of life for myeloma patients; however, this has the potential for unwanted side effects in the oral cavity and maxillofacial region. Osteonecrosis of the jaw related to antiresorptive medications and other myeloma therapies is not uncommon. This review serves to highlight the risk of osteo

Bridging the gap - Establishing a dental-oncology service in a cancer centre.

Dental disease remains the most common non-communicable disease worldwide. It predisposes patients to significant morbidities following bone modifying agents or radiation therapy to the head and neck. Preventative dental regimes effectively reduce the risk of both medication-related osteonecrosis of the jaw (MRONJ) and osteoradionecrosis (ORN) in these patients. Co-ordination of routine dental care as a component of mainstream oncology treatment optimises long term outcomes for oncology patients. This case series offers insights into patient, institutional and social difficulties that challeng
