Lung cancer metastasizing to salivary glands: Systematic review.

ABSTRACTS: Metastasis to salivary glands from the secondary source outside the head and neck region is extremely rare and Carcinoma Lung is one of the rarest sources of distant spread to salivary glands. Owing to missed diagnosis and misdiagnosis, accurate identification of clinical and pathological aspects of these metastatic lesions remains a challenging task. Many studies regarding metastasis to the oral cavity have been already documented in the literature, but very little research work has been done to analyse the cases of lung cancer metastasis as the sole primary source, particularly to salivary glands. Thus this review was conducted to analyse the published cases of lung cancer metastasizing to salivary glands as the only primary source till date. An electronic search of the published literature was performed without publication year limitation in PubMed/ Medline, Scopus, Google Scholar, Web of Science, Science direct, Embase, and Research gate databases, using Mesh keywords like (Lung cancer', OR 'Lung carcinoma), AND (Metastasis OR Metastases), And (Salivary glands OR Parotid gland OR Submandibular gland OR Sublingual gland). We also searched all related journals manually. The reference list of all articles was also checked. Our research revealed 34 relevant papers between 1965-2022 with a total of 44 patients. The most prevalent diagnosed metastatic Lung cancer was Small cell lung cancer. Parotid was the most common gland involved in metastasis. 48% of patients died of metastasis with a mean survival time of 2.2 years. Salivary gland metastasis from Lung cancer is very rare and has a poor prognosis. More cases need to be published in order to raise awareness of these lesions and gain a better understanding of their characteristics.

Lung cancer metastasis to oral soft tissues; Systematic review of 122 cases.

Background: Lung cancer metastasis to oral region is very rare. Studies have been published analysing the cases of metastatic tumours to the oral cavity by many researchers. But very few research work has been conducted till date to analyse only the oral soft tissue metastasis from Lung cancer as the primary source. The goal of this study was to examine published cases of oral soft tissue metastasis from lung cancer as the only primary source from 1st August 1977 to 31st December 2021. Material and Methods: An electronic search of the published English literature was performed in PubMed/ Medline, Scopus, Google Scholar, and Research gate databases, using keywords like 'Lung cancer', OR/ AND 'Lung carcinoma' OR/ AND 'Oral cavity', OR/AND 'Metastasis', OR/AND 'Primary', OR/AND 'Source', OR/AND 'Initial', OR/AND 'Tongue', OR/AND 'Palate', OR/ AND 'Tonsil', OR/AND 'Lip', OR/AND 'Buccal mucosa', OR/AND 'Floor of mouth', OR/AND 'Salivary glands', OR/ AND 'Parotid', OR/ AND 'Submandibular', OR/ AND 'Sublingual' OR/ AND 'Mandible', OR/AND 'Maxilla. We also searched all related journals manually. Reference list of all articles was also checked. Results: Our research revealed total 122 patients. The most prevalent diagnosed metastatic lung cancer was adenocarcinoma. Gingiva, tongue and tonsils were the most common site of metastasis. 54% patients died of metastasis with a survival time of 1 week to 2.5 years. Conclusions: Oral soft tissue metastasis from lung cancer has a bad prognosis. More cases need to be published in order to raise awareness of these lesions and gain a better understanding of their characteristics. Key words:Lung cancer, metastasis, oral, primary, soft tissues.

Agenesis of permanent canines: Rare case report.

Agenesis of permanent canines is a rare condition, and that of both maxillary and mandibular permanent canines is extremely rare. It may occur either isolated or in association with other dental anomalies. Reports of such cases are very scarce in the literature. Need for early diagnosis of such conditions should be emphasized because of functional, esthetic, and psychological problems which should be evaluated and treated appropriately. The present paper presents a report of bilaterally missing permanent maxillary and mandibular canines. This case might contribute in the future studies of incidence of agenesis of permanent canines.

Intraoral Approaches for Maxillary Molar Distalization: Case Series.

Correction of Class II malocclusion by distalization of maxillary molars with intraoral appliances is a non-extraction treatment approach, which has been described as an alternative to Head Gear. From the past few years, the procedures have undergone rectification to achieve treatment objective more precisely. This has been made possible by a better understanding of bone physiology, tooth movement, biomechanics and newer biomaterials. Nowadays newer distalizing appliances, like the Jones Jig, Lokar distalizer and Carrière distalizer, have been developed which have compact designs and cause minimal discomfort to the patient. Refinement in these appliances is concentrated mainly on achieving bodily movement of the molar rather than simple tipping. These appliances are also operator friendly as these are easy to insert and remove. The present case series presents the efficacy of these appliances in Class II malocclusion patients with a mean age of 16 years (age range of 15-17 years) that reported with the chief complaint of irregular upper front teeth, since non-extraction approach in correcting Class II malocclusion is gaining a lot of attention.

Pain Perception and Personality Trait toward Orthodontic Treatment.

AIM: The study was done to evaluate the pain perception, attitude, and personality trait of the patient toward orthodontic treatment. MATERIALS AND METHODS: In this cross-sectional questionnaire survey, 100 patients were divided into Group 1, 150 (75 males and 75 females) as untreated group and Group 2, 150 as treated group (75 males and 75 females). Evaluation of the patients was done based on pain perception, attitude, and personality trait. Set of questionnaire was used to assess attitude and pain perception on visual analog scale. The data were tabulated, and statistical evaluation was done using statistical software IBM SPSS Statistics for Windows, (Version 21.0. Armonk, NY: IBM Corp.) using t-test and Tukey's test. RESULTS: The mean pain perception for Group 1 was 4.8 ± 1.30 and 4.17 ± 1.58 in Group 2; the difference was not statistically significant (P = 0.26). The mean value for attitude in Group 1 was 3.57 ± 1.21, and in Group 2, it was 3.39 ± 1.60 (P = 0.09). There was statistically significant difference in pain perception between low (L) level to high level (H) neuroticism (P = 0.009). There was significant difference (P = 0.021) in pain for conscientiousness from very low to very high levels which is directly proportional. CONCLUSION: The present study indicated that attitude, personality traits, and pain perception have a definite role in patient cooperation and success of orthodontic treatment.

An Odontometric Approach for Estimation of Stature in Indians: Cross- Sectional Analysis.

INTRODUCTION: Height/stature is one of the useful anthropometric parameter for individual identification. Correlation of stature to long bones, even fragmentary bones is frequently reported among various populations. As teeth have the advantage of being composed largely of hard tissue which is relatively indestructible, the careful study of these can enable reliable determination of stature of the person in life. AIM: The present study was designed to elucidate the anthropometric correlation of tooth dimensions with stature and also devises regression formulae. MATERIALS AND METHODS: This study was carried out on 361 Indian students (151 males and 210 females) in the age range of 21- 45 years to estimate stature using odontometry. Stature and tooth measurements were taken on each partcipant following standard methods and techniques. Karl Pearson's correlation co-efficient and linear regression was used to estimate stature. RESULTS: Regression analysis showed that the canine width can aid in estimation of stature as an adjunct when only teeth are available for identification. CONCLUSION: Tooth dimensions can be used only as a supplementary approach for the estimation of stature but with caution.

Dental and periodontal health status of Beta thalassemia major and sickle cell anemic patients: a comparative study.

BACKGROUND: This study aimed to assess the dental and periodontal health status of beta thalassemia major and sickle cell anemic patients in Bilaspur, Chattishgarh, India. MATERIALS & METHODS: A total of 750 patients were included in the study. The patients were randomly divided into three groups I (n=250), II (n=250) and III (n=250), ranging from 3-15 years. After performing a thourough general examination, including their demographic data, intraoral examination was done using Decayed-Missing-Filled Teeth Index (DMFT Index), Plaque index (PI) and Gingival index (GI). Statistical analysis was done using statistical software SPSS 17.5 version. Chi square test & student t test was used for the comparison of study and control groups. The level of significance was set at P<0.05. RESULTS: In the present study, it was found that, prevalence of dental caries and periodontal diseases was significantly more in beta thalassemic patients followed by sickle cell anemic patients than control group. However, when group I (beta thalassemia) was compared with group II (sickle cell anemia), results were found to highly significant (P<0.001) only for decayed missing filled tooth. CONCLUSION: Appropriate dental and periodontal care improves a patient's quality of life. Preventive dental care is must for thalassemic and Sickle cell disease patients.
