Prevalence, length, and patterns of Anterior Loop among the South Indian population: A comparative study between Panoramic Radiography and Cone Beam Computed Tomography.

Purpose: To assess the prevalence, length, and patterns of the anterior loop of the inferior alveolar nerve by panoramic radiography and cone beam computed tomography (CBCT). Materials and Methodology: A prospective study was conducted on 300 mental foramen regions by exposing them to panoramic radiography and CBCT scan. Two individual observers evaluated the images to assess the presence of an anterior loop, the mean length of the loop, and the most frequent pattern of the loop in our population. Result Analysis: The prevalence of the anterior loop for male patients and female patients by panoramic radiography was 34% and 32% on the right side and 30% and 36% on left side, respectively. By CBCT, the corresponding values were 69% and 72% on the right and left side, respectively, for male patients, and 73% and 81% on the right and left side, for female patients, respectively. Conclusion: The results from our study strongly emphasize the need for CBCT imaging before planning for procedures in the mental foramen region because the prevalence, length, and pattern of loop significantly varies with respect to age, sex, and population.

Assessment of the efficacy of digital panoramic radiographs in analyzing changes in bone mineral density in postmenopausal women.

Introduction: Osteoporosis is described by the World Health Organization (WHO) as a 'progressive systemic skeletal disease characterized by low bone mass, microarchitectural deterioration of bone tissue, a consequent increase in bone fragility, and susceptibility to fracture. The maxilla and mandible are also affected by osteoporotic changes and these may be visualized using an Orthopantomogram. Aims and Objectives: To determine the radiomorphometric indices in the digital orthopantomograms, to determine the bone mineral density (BMD) of the lumbar spine and femur using DXA (Dual-Energy X-ray Absorptiometry) scan, to compare the measured indices between the BMD categories and to assess the correlation of these indices with the measured BMD. Materials and Methods: The study population included 30 postmenopausal female patients. The BMD was measured at the lumbar spine and at the femur and the patients were divided into three groups of 10 subjects based on their BMD status (normal, osteopenia, and osteoporosis). The patients were then subjected to panoramic radiography and four panoramic indices were assessed (simple visual estimation, mandibular cortical index, mental index, and antegonial index). The measured indices were compared between the three BMD categories. The correlation between the indices and the BMD was also observed. Results: The measured indices showed significant difference among the BMD categories. The quantitative indices also demonstrated a positive correlation with the measured BMD of the lumbar spine and the femur. Conclusion: Panoramic radiography may be used as a diagnostic tool for screening and identifying subjects who are likely to have osteoporosis.

Xerostomia - A Comprehensive Review with a Focus on Mid-Life Health.

Xerostomia is defined as the subjective complaint of a dry mouth. Xerostomia is common in menopausal women owing to the hormonal changes which take place during midlife. Studies show a higher incidence of oral cancer in the postmenopausal period which substantiates the theory of estrogen deficiency in carcinogenesis. Radiotherapy in the treatment of these cancers can lead to oral dryness. Other etiological factors of xerostomia include systemic diseases commonly occurring in middle-aged individuals and xerogenic drugs. Saliva plays a pivotal role in the maintenance of oropharyngeal health and xerostomia can severely impair the quality of life. The aim of this review was to provide vital information pertaining to the etiology, signs, diagnosis, and treatment of xerostomia with an emphasis on midlife health. The articles for this review were obtained from PubMed Central, Google Scholar, EBSCO, Science Direct, Medknow, Scopus, EMBASE, Web of Science, and authorized textbooks published between 1988 and 2021.

Palliative Psychiatry for Patients With Severe and Persistent Mental Illness: A Survey on the Attitudes of Psychiatrists in India Compared to Psychiatrists in Switzerland.

Objectives: Palliative psychiatry is a new approach for the care of patients with severe and persistent mental illness (SPMI) which systematically considers biological, psychological, social, and existential factors of care. To assess the attitudes of psychiatrists in India toward palliative psychiatry for patients with SPMI and to compare these to the attitudes of psychiatrists in Switzerland. Methods: In an online survey, data from 206 psychiatrists in India were collected and compared with data from a previous survey among 457 psychiatrists in Switzerland. Results: Psychiatrists in India generally considered it very important to prevent suicide in SPMI patients (97.6%). At the same time, they considered it very important to reduce suffering (98.1%) and to ensure functionality in everyday life (95.6%). They agreed that palliative psychiatry is important for providing optimal care to SPMI patients without life-limiting illness (79.6%) and considered palliative psychiatry as indicated for patients with SPMI (78.2%). By contrast, curing the illness was considered very important by only 39.8 % of respondents. Relative to psychiatrists in Switzerland, psychiatrists in India were significantly more concerned about preventing suicide and less willing to accept a reduction in life expectancy, even at the expense of quality of life in patients with severe and persistent schizophrenia and recurrent major depressive disorder. At the same time, they were significantly more likely to advocate palliative psychiatry. Conclusion: Most of the participating psychiatrists in India agreed that palliative psychiatry can be indicated for patients with SPMI. The comparison with psychiatrists in Switzerland highlights the need to take account of cultural differences in future studies of this kind. In summary, this study shows the potential of palliative psychiatry as a genuine biopsychosocio-existential approach which systematically integrates biological, psychological, social, and existential factors of care.

Exploring the Family factors associated with Suicide Attempts among Adolescents and Young Adults: A Qualitative Study.

BACKGROUND: Suicides are among the leading cause of death among adolescents and young adults worldwide, including India. Suicide attempts are about 20 times more common than completed suicides. Teenagers and youth who attempt suicide belong to a heterogeneous group. Various biological and psychosocial factors, including family factors, contribute to such behavior. Quality of family functioning and relationships may act as an important contextual factor in deciding suicidal behavior. Hence, this study was done to explore the family factors contributing to suicide attempts. METHODS: Qualitative exploratory study design and purposive sampling were used. Data were collected from 22 adolescents and young adults using an in-depth interview method. All audio recordings were transcribed in Malayalam, and then translated to English. Codes were developed using the qualitative data analysis software. Thematic analysis was done. Themes and relationships were identified and synthesized to a framework that represents the summary of the data. RESULTS: Most of the participants perceived the home environment as hostile. Problems within the family included parental conflicts and separation, conflict with a sibling or other members of the family, and marital disharmony. Most of them perceived low family support. Socioeconomic factors such as financial issues, superstitious beliefs, disturbing neighborhoods, interpersonal issues, and the stigma of having a mental illness, in a family member, were also noted. CONCLUSION: Hostile family environment, faulty interactions between family members, and lack of perceived family support may contribute to suicidal behavior among adolescents and young adults. Hence, it is imperative to consider these factors while treating them or planning any suicide prevention program for them.

A case report on granular cell ameloblastoma - A rare histological entity.

Granular cell ameloblastoma is a rare condition, accounting for 3.5% of all ameloblastoma cases that shows marked transformation in the cytoplasm of tumor cells, which are usually stellate reticulum-like cells. The transformed cells possess very coarse, granular eosinophilic cytoplasm. Granular cell ameloblastoma is aggressive in nature with a marked propensity for recurrence and can progress to metastasis. This article discusses a case report of a 35-year-old female patient diagnosed with granular cell ameloblastoma of the right mandible.

Ghost teeth: Regional odontodysplasia of maxillary first molar associated with eruption disorders in a 10-year-old girl.

Regional odontodysplasia (RO) is an uncommon, developmental anomaly of the dental hard tissues that affects ectodermal and mesodermal dental components with characteristic clinical and radiographic findings. Clinically, RO affects a particular segment in either or both dentitions in the maxilla or mandible or both jaws. Radiographic features have consistently demonstrated thin and defective layers of enamel and dentine, resulting in a faint, fuzzy outline, creating a ghost-like appearance. The RO etiology is uncertain; numerous factors have been suggested and considered as local trauma, irradiation, hypophosphatasia, hypocalcemia, hyperpyrexia. A case of RO in a 10-year-old girl whose chief complaint were forwardly placed upper front teeth and the absence of eruption of permanent teeth. Clinical and radiographic features are described.

The assessment of sagittal changes with twin block appliance in patients with decelerating growth phase.

INTRODUCTION: The main reason for seeking orthodontic treatment for Class II malocclusions is aesthetic improvement. Growth modification treatment procedures offer better results for a patient with significant potential growth. AIM: The aim of this cephalometric clinical study was to distinguish skeletal and dental corrections on skeletal class II division I growing subjects with Twin Block therapy (TB) and the changes were assessed using SO-analysis by Pancherz. MATERIALS AND METHODS: Strict diagnostic protocol viz. growing individuals with horizontal growth pattern, skeletal class II due to retrognathic mandible with positive VTO, bilateral class II molar relation, minimal crowding in either arch or overjet more than 5mm was used. Out of 28 selected cases,17 patients received TB therapy and 11 patients were maintained as control group. Standard removable TB appliances with lower incisor capping were delivered to treatment group. The horizontal advancement was about 8mm and 2-3mm vertical opening between the upper and lower central incisors were maintained for all the cases. The mean time interval between the initial (T1)and post treatment (T2) cephalograms of Twin-Block group was 11 month,with a range of 8 month to 13 month. In the control group, the mean time interval between the first (C1)and second (C2) cephalometric films was 12 month,with a range of 10 month to 14 month.T1and T2 cephalograms were traced and S-O analysis was used to segregate dental and skeletal effects. STATISTICAL ANALYSIS: SPSS software was used for statistical analysis. RESULTS: Skeletal Changes: In this study, the mean movement of maxilla was 0.67mm which represents significant restriction of forward maxillary growth in contrast to control groups. Dental Changes: In this study the maxillary molars appear to move distally with a mean value of 0.13mm. Comparing this to the movement of maxillary jaw base itself, maxillary distal movement of molar is less. But still it contributes to Class II correction. CONCLUSION: The overjet reduction and molar relation correction are more skeletal in nature.

Acquired acid resistance of human enamel treated with laser (Er:YAG laser and Co2 laser) and acidulated phosphate fluoride treatment: An in vitro atomic emission spectrometry analysis.

BACKGROUND: Dental caries is essentially a process of diffusion and dissolution. If the aspect of dissolution can be curtailed some degree of prevention can be achieved. AIMS: The present study was carried out to evaluate and compare the effect of Er:YAG laser and Co2 laser irradiation combined with acidulated phosphate fluoride treatment on in vitro acid resistance of human enamel. DESIGN: An in vitro study was carried out on 30 human premolars to evaluate the enamel's acid resistance using an atomic emission spectrometry analysis. MATERIALS AND METHODS: A total of 60 enamel specimens were prepared from 30 human premolars and were randomly assigned to 6 groups: (1) Untreated (control); (2) 1.23% acidulated phosphate fluoride (APF) gel application alone for 4 min; (3) Er:YAG laser treatment alone; (4) Co2 laser treatment alone; (5) Er:YAG laser + APF gel application; (6) Co2 laser + APF gel application. The specimens were then individually immersed in 5 ml of acetate buffer solution (0.1 mol/L, pH 4.5) and incubated at 37°C for 24 h, and the acid resistance was evaluated by determining the calcium ion concentration using the atomic emission spectrometry. STATISTICAL ANALYSIS: An ANOVA model was constructed (P value of 0.05), followed by Tukey's test for multiple pair wise comparisons of mean values. RESULTS: Significant differences were found between the control group and the test groups (P < 0.001). CONCLUSIONS: Combining acidulated phosphate fluoride with either Er:YAG or Co2 laser had a synergistic effect in decreasing the enamel demineralization more than either fluoride treatment or laser treatment alone.

Psychosocial stressors and patterns of coping in adolescent suicide attempters.

CONTEXT: Different risk factors associated with adolescent suicide attempts have been identified including those of socio-demographic and clinical variables. Relatively, little research has been done in the area of their stressors and coping patterns. AIMS: To study the recent psychosocial stressors and patterns of coping associated with adolescent suicide attempts. SETTINGS AND DESIGN: Tertiary care hospital, case-control study. MATERIALS AND METHODS: One hundred consecutive cases of adolescent attempted suicide admitted to the hospital and an equal number of controls, matched individually for age and sex, from the relatives and friends of other patients in the ward, were studied. Assessment included details regarding socio-demographic data, psychiatric and physical morbidity, their recent stressors, and patterns of coping. Stressors were assessed using Presumptive Stressful Life Event Scale and coping strategies by Ways of Coping Questionnaire (revised). STATISTICAL ANALYSIS: Chi-square test and multivariate logistic regression analysis. RESULTS: The number of stressful life events and mean stress scores in the preceding 1 month and certain coping strategies such as confronting, distancing, and escape-avoidance were found to be significant risk factors associated with adolescent suicide attempts. Strategies such as self-control, seeking social support, accepting responsibilities, problem solving, and positive appraisal act as protective factors. CONCLUSIONS: Recent stressors and strategies such as confronting, distancing, and escape-avoidance are significant risk factors associated with adolescent suicide attempts, whereas certain coping strategies act as protective factors. Teaching adolescents these protective coping patterns may be a promising strategy for prevention of adolescent suicide attempts.
