    4.3.1. Standardization culture

    In health care system, the most case of patients is presented with medical pathology 
    of oral cavity and esophagus such dental caries/teeth, oral pharyngeal candida, 
    injuries, esophagitis. The learners have to learn oral diseases and esophagus in 
    order to handle and to manage the patients with oral cavity and esophagus related 
    diseases.

    4.3.2. Inclusive education
    The teacher involves the students in all learning activities concerning the kind of 
    learner or disabilities for example the slow learner should be reinforced in order to 
    catch up others, and the teacher takes into consideration respective disability of 
    learner.

    Grouping students, Students with special educational needs are grouped 
    with others and assigned roles basing on individual student’s abilities.
    Providing earning resources earlier before teaching session so that students get 
    familiar with them. After end lesson assessment, the identified slow learners are 
    exposed to the remedial learning activities.

    Every important point is written and spoken. The written points help students with 
    hearing impairment and speaking aloud helps students with visual impairment.
    Remember to repeat the main points of the lessons.

    1.6 Summary of the unit
    Medical pathology is a branch of medical science primarily concerning the diseases 
    affects different human organs such as respiratory tract organs, cardio-vascular 
    organs, digestive organs, uro-genital organs, sensory organs etc. This unit of 
    medical pathology of the oral and esophagus described the most common oral 
    cavity and esophagus conditions that are frequently observable in Rwanda such 
    dental caries/teeth, oral-pharyngeal candidiasis, injuries and esophagitis. The 
    medical conditions of oral and oesophagus are described by the definition, clinical 
    features, causes and risk factors, pathophysiology, investigation, treatment plan, 
    evolution and complications. The student who will be complete this content will 
    be able to take appropriate decision on different common medical pathologies in 
    terms of diagnosing, treatment and prevent the complication of dental caries, oral 
    pharyngeal, injuries and esophagitis. 

    1.7 Additional Information 
    Common additional oral cavity disorders.
    • Gingivitis
    • Cancer of the esophagus

    1. GINGIVITIS
    Gingivitis is an often-painful inflammation of the gums, or gingiva. It typically occurs 
    due to plaque buildup on the teeth. People may generally refer to this as gum 
    disease. Gingivitis is an early form of gum disease and typically produces mild 

    symptom

    Causes
    The most common cause of gingivitis is the accumulation of bacterial plaque 
    between and around the teeth. Dental plaque is a biofilm that accumulates naturally 
    on the teeth. It occurs when bacteria attach to the smooth surface of a tooth.
    Several underlying conditions and outside factors trusted source can increase plaque 
    formation or a person’s risk of gum inflammation. Changes in hormones: this may 
    occur during puberty, menopause, the menstrual cycle and pregnancy. The gums 
    might become more sensitive, raising the risk of inflammation. Some diseases: 
    cancer, diabetes and HIV are linked to a higher risk of gingivitis; medications that 
    reduce saliva production can affect a person’s oral health. Dilantin, an epilepsy 
    medication, and angina drugs can also cause abnormal growth of gum tissue, 
    increasing the risk of inflammation, smoking, age, family history of gingivitis are 
    also a risk factor of gingivitis.

     Signs and Symptoms 
    The signs and symptoms of gingivitis might include gum inflammation and 
    discoloration, tender gums that may be painful to the touch, bleeding from the gums 
    when brushing or flossing, halitosis or bad breath, receding gums, soft gums
    However, in mild cases of gingivitis, there may be no discomfort or noticeable 
    symptoms

    Adequate diagnosis
    A dentist or oral hygienist will check for symptoms, such as plaque and tartar in the 
    oral cavity. They may also order tests to check for signs of periodontitis. This can 
    be done by x-ray or periodontal probing, using an instrument that measures pocket 
    depths around a tooth

    Treatment Plan
    If diagnosis happens early and treatment is prompt and proper, a person may be 
    able to treat gingivitis at home with good oral hygiene. However, if symptoms do 
    not resolve, or the condition affects a person’s quality of life, they may wish to seek 
    professional help.
    Treatment often involves care by a dental professional and follow-up procedures 
    carried out by the patient at home. A person may be able to prevent gingivitis at 
    home by practicing regular good oral hygiene. This includes brushing teeth at least 
    twice a day, using an electric toothbrush, flossing teeth at least once a day, regularly 

    rinsing the mouth with an antiseptic mouthwash Top of Form

    Complications
    Some complications include abscess or infection in the gingiva or jawbone, 
    periodontitis a more serious condition that can lead to loss of bone and teeth, 
    recurrent gingivitis, trench mouth, where bacterial infection leads to ulceration of 
    the gums

    2. Cancer of Esophagus
    Oesophageal cancer is a serious condition. Clients usually do not experience 
    symptoms until the disease has progressed to interfere with swallowing and 
    passage of food, leading to weight loss.

    Causes and risk factors
    The major cause of oesophageal cancer is chronic irritation of the oesophagus from 
    any source. Alcohol abuse and cigarette smoking, clients with GERD are at higher 
    risk for adenocarcinoma of the oesophagus, other risk factors include habitual 
    ingestion of hot liquids or foods, poor or inadequate, oral hygiene, and nutritional 
    deficiencies

    Signs and symptoms
    Mild, with vague discomfort and difficulty swallowing some foods, Weight loss, 
    progressive dysphagia. As the disease continues the client resorts to consuming 
    liquids only.
    He or she may experience regurgitation of food, haemorrhage, haemoptysis 
    (Vomiting of blood), back pain and respiratory distress due to expansion of the 
    tumour, loss and weakness.

    Investigation
    A barium swallow demonstrates a filling defect caused by a space-occupying mass. A 
    biopsy of tissue removed during esophagoscopy or an esophagogastroduodenoscopy 
    reveals malignant cells.

    A bronchoscopy may determine whether the cancer cells have affected the trachea. 
    Computed tomography (CT) of the chest and abdomen to determine whether 
    metastasis has occurred. If oesophageal cancer is diagnosed in early stages, 

    treatment.

    Treatment Plan
    If oesophageal cancer is diagnosed in early stages, treatment is directed at a cure 
    and includes surgery, chemotherapy, and/or radiation. The surgery is a complete 
    resection of the oesophagus (esophagectomy), which involves removing the tumor 
    and a wide margin of tumor-free tissue as well as surrounding lymph node
