Anatomical Variants of Condylar Process, Coronoid Process, and Sigmoid Notch in a Maharashtrian Population: A Radiographic Study.

Background The cornerstone of an individual's singularity is identification. Digital orthopantomography (OPG) helps to illustrate the varying condylar process, coronoid processes, and sigmoid notch found within a population to facilitate individual recognition. This study aims to assess the various shapes of the condylar process, coronoid process, and sigmoid notch found using OPG in a sample population of an Indian city. Methodology This retrospective, cross-sectional study was conducted using 1,000 good-quality digital OPG scans to evaluate the different shapes. The scans were evaluated by two experienced oral radiologists and tabulated for statistical analysis. Results The current investigation revealed varied morphological forms of the three entities, with the round shape being the most frequently observed condylar process, coronoid process, and sigmoid notch. Comparisons across sides and between sexes revealed differences in all three variables which were found to be statistically significant. We discovered a crooked finger condyle (58.56% on the left side and 41.44% on the right side), a beak-shaped coronoid process (50.0% on the left side and 50.0% on the right side), and a V-shaped sigmoid notch (41.35% on the left side and 58.65% on the right side) in this study. This is a unique finding not reported by other studies. Conclusions Analyzing the shape of the condylar process, coronoid process, and sigmoid notch found on an OPG scan can help with gender identification in forensic odontology and anthropology as these anatomical features show strong sexual dimorphism.

Efficacy of Sodium Bicarbonate-Buffered Local Anesthetic Solution in Cases Requiring Bilateral Maxillary Premolar Orthodontic Extraction: A Comparative Split-Mouth Study.

Aims and objectives This study was carried out to evaluate the efficacy of 8.4% sodium bicarbonate-buffered local anesthetic solution and conventional local anesthetic in patients requiring bilateral maxillary orthodontic extractions in terms of pain on injection, onset of action, and duration of action. Methods 102 patients requiring bilateral maxillary orthodontic extractions were included in the study. Buffered local anesthetic was administered on one side while conventional local anesthesia (LA) was administered on the other side. Pain on injection was measured using a visual analogue scale, while onset of action was measured by probing the buccal mucosa after 30 seconds of administration and duration of action was measured by the time after which the patient experienced pain or took a rescue analgesic. The data was statistically analyzed to determine the significance. Results The pain during injection was found to be lesser at sites where buffered local anesthetic was administered (mean visual analogue scale (VAS) score = 2.4) as compared to conventional local anesthetic (mean VAS score = 3.9). The onset of action was faster with buffered local anesthetic (mean value = 62.3 seconds) as compared to conventional local anesthetic (mean value = 157.16 seconds). Lastly, the duration of action was found to be longer for buffered local anesthetic group (mean value = 225.65 minutes) as compared to conventional local anesthetic (mean value = 187 minutes). Conclusion 8.4% sodium bicarbonate-buffered local anesthetic was found to be more efficient than conventional local anesthetic in terms of reduction in pain on injection as well as faster onset and longer duration of action.

Rehabilitation of Post-traumatic Anterior Maxillary Osseous Deficit Using Iliac Onlay Bone Graft Combined With Dental Implants.

Fracture of the anterior maxilla usually causes a scooped-out defect in this region which leads to loss of lip support and a sub-optimal condition for placement of implants. The iliac crest is a frequently used donor location in oral and maxillofacial procedures for bone augmentation in order to restore jaw deformities brought on by trauma or pathological diseases prior to the placement of dental implants. Here we present the case of a patient who had undergone reconstruction of the maxillary osseous defect caused due to trauma by iliac crest grafting, followed by placement of dental implants after six months.

Factors delaying chemotherapy in patients with breast cancer at a safety-net hospital.

BACKGROUND: Despite advances in healthcare and improved chemotherapy, disparities in breast cancer outcomes continue to persist. Our aim was to evaluate socioeconomic factors that may impact timing of treatment for patients receiving chemotherapy in underserved communities. METHODS: A review of patients with breast cancer who received neoadjuvant or adjuvant chemotherapy from 2015-2019 was conducted at a safety-net hospital. The primary outcomes were times from diagnosis to chemotherapy and surgery. Clinicodemographic factors including race, age, clinical stage, primary language, comorbidities, and median income by zip code were collected. Multivariable regression analysis was performed to evaluate for factors associated with the primary outcomes. RESULTS: One hundred patients were identified. For the neoadjuvant group, median time from diagnosis to chemotherapy and surgery was 52 ± 34 days and 256 ± 59 days, respectively. For the adjuvant group, median time from diagnosis to surgery and chemotherapy was 24.5 ± 18 days and 94.5 ± 53 days, respectively. Non-English language and older age were associated with increased time to chemotherapy in the adjuvant group (p < 0.05). Language and age were not associated with increased time to surgery in both groups. Race, age, comorbidities, and income were not associated with delay in treatment in either groups. CONCLUSIONS: Older age and non-English language were associated with prolonged time from surgery to adjuvant chemotherapy. Targeted interventions directed at patient education and decreasing language barriers especially post-operatively may decrease delays in treatment and subsequently reduce disparities seen in the breast cancer population.

High Compliance With Choosing Wisely Breast Surgical Guidelines at a Safety-Net Hospital.

BACKGROUND: Professional organizations recently set guidelines for avoiding surgeries of low utility and overutilization for the Choosing Wisely campaign. These include re-excision for invasive cancer close to margins, double mastectomy in patients with unilateral breast cancer, axillary lymph node dissection in patients with limited nodal disease, and sentinel lymph node biopsy (SLNB) in patients ≥70 years with early-stage breast cancer. Variable adherence to these recommendations led us to evaluate implementation rates of low-value surgical guidelines at a safety-net hospital. METHODS: We retrospectively analyzed breast cancer patients who underwent surgery from 2015 to 2020. Each patient was assessed for eligibility for omission of the listed surgeries. Trends were evaluated by cohorts before and after a fellowship-trained breast surgeon joined the faculty in 2018. Outcomes were compared using Fisher's exact test. RESULTS: Among 195 patients, none underwent re-excision for close margins of invasive cancer. Only 6.7% of patients (3/45) received contralateral mastectomy and 1.8% of eligible patients (3/169) received axillary lymph node dissection. Overall, 60% of patients ≥ 70 years with stage 1 hormone-positive breast cancer (9/15) received SLNB. There was a downward trend from 71% of eligible patients receiving SLNB in 2015-2018 to 50% in 2019-2020. CONCLUSIONS: De-implementation of traditional surgical practices, deemed as low-value care, toward newer guidelines is achievable even at community hospitals serving a low socioeconomic community. By avoiding overtreatment, hospitals can achieve effective resource allocation which allow for social distributive justice among patients with breast cancer and ensure strategic use of scarce health economic resources while preserving patient outcomes.
