Introduction: Selection of proper tooth shade is one of the most significant factors influencing patients’ aesthetic perception and improved prosthesis acceptance. Guidelines in the dental literature suggest age, sex, colour of skin, hair and eye for selecting tooth shade when past records cannot be obtained. The objective of the study was to observe the most common tooth shade in relation to the skin colour and the prevalence of the same in relation to age and sex. Methods: A descriptive cross-sectional study was carried out at Kathmandu Medical College from June to August 2019. Vitapan Classical Shade guide was used to select the shade of upper right central incisorin 338 participants. Revlon Foundation Makeup Shade guide was used to determine colour of skin. Participants were examined without facial makeup. Skin colour and teeth shade were examined in daylight at about sametime of the day. Data obtained were computed and analysed using Microsoft Excel 2016 software. Results: Prevalence of tooth shade with high value (lighter shade) was seen in all fair (121, 35.8%), medium (63, 18.6%) and dark skin tones (23, 6.8%). Most common teeth shade in fair individuals was B1 (47, 37.9%), in medium also B1 (25, 7.4%) and dark was B2 (9, 2.7%). Age range of 10 to 35 years had tooth shade with higher value (159, 47.04%). Conclusions: Hence, teeth shade with high value (lighter shade) was prevalent in skin tone of all types in current study. Skin tone was not related to teeth shade selection, teeth became darker with age and females had lighter teeth shade (high value).
Introduction: Dental treatment aims at correction of existing disease; prevention of future diseasewith rehabilitation of patient’s lost functional capacity and aesthetics. Fixed dental prosthesis is anyprosthesis that is cemented to a natural tooth or dental implants abutments that cannot be removedby patient. The success of prosthodontic treatment is related to prosthesis survival, with its ability tofulfil biologic and patient-evaluated objectives with patient satisfaction. This study is aimed to findthe patient satisfaction with fixed prosthodontic treatment. Methods: This descriptive cross-sectional study was done in a tertiary care hospital among 102patients rehabilitated with fixed dental prosthesis from August to September 2019 after takingethical approval from Institutional Review Committee of Kathmandu Medical College. (IRC No.1207201918). Convenience sampling was done. The questionnaire assessed patient’s satisfaction offixed prosthesis on the basis of appearance, chewing ability, cleansibility, speech and awarenessof oral hygiene measures for cleaning of the prosthesis. Data entry was done in Microsoft exceland analysed using Statistical Package for Social Sciences (SPSS)version 20.0, point estimate at 95%Confidence Interval was calculated along with frequency and proportion for binary data. Results: The majority of the patients 87 (85.3%) were satisfied with their fixed prosthesis, at 95%confidence interval (93.5- 81%). Eighty one (79.4%) were satisfied with their chewing ability; 99(97.1%) satisfied with their speech, 78 (76.4%) satisfied with appearance of fixed prosthesis. Ninetyeight patients (96.1%) were aware of oral hygiene measures, out of which only 66 (67.3%) usedinterdental aids for cleaning of their fixed prosthesis. Conclusions: Several factors (chewing ability, appearance, speech, cleansibility of fixed prosthesis)had positive impact on overall satisfaction in majority of the patients. Dentists should continue toemphasise on the significance of maintaining good oral hygiene and use of interdental aids for thelongevity of fixed prosthesis.
Introduction: The aim of the study was to determine the most reliable ala-tragus line for the orientation of the occlusal plane in edentulous patients during complete denture fabrication by cephalometry. Materials and Methods: Lateral cephalometric radiographs of 37 dentate subjects were taken at maximum intercuspation. Steel balls were used as radio opaque markers which were adhered to superior border, middle point, and inferior border of tragus as well as the inferior border of ala of nose. Lead foil was cemented to cover the mesio-palatal cusp of maxillary first molar. Tracings of cephalogram were done. Angle between ala-tragus superior, ala-tragus middle and ala-tragus inferior in relation to occlusal plane were measured. Variables were determined and data were analyzed using SPSS version 17 (SPSS, Inc. Chicago, III). Results: The angle formed between occlusal plane and ala tragus middle had lowest mean value of 2.39°. The highest was measured with ala tragus superior 5.18°, while the angle formed with ala tragus inferior was 3.60°. The differences between the three planes in relation to the occlusal plane were significantly different in total subjects as well as in both males and females (p < 0.001). Conclusion: Statistical analysis showed that the middle point of the tragus with the inferior border of the ala of the nose was most accurate in orienting the occlusal plane.
Introduction: Dental professionals are at the risk of exposure to wide varieties of microorganisms from blood and saliva of patients to airborne infection from microbial-laden aerosols and spatter created during laboratory procedures. Dental laboratories are usually disregarded when planning effective infection and exposure control measures. Contaminated impression may act as a vehicle for transmission of infectious agents. Objective: The objective of this study was to assess the practice of dental technicians towards infection control and to evaluate practice of the same for dental impressions in commercial dental laboratories. Methods: Self-administered standard questionnaire was distributed to 35 dental laboratories and 31 participated in the study. The answers were collected by the investigators themselves. The data obtained were computed and analysed to find the results. Results: Among all dental laboratories, 21 (67.75%) ensure dental impression is disinfected in clinic. 18 (58.06%) wear gloves when receiving clinical items and 27 (87.10%) transfer the items in separate sealed plastic bag. Of all, 25 (80.64%) of the dental laboratories have separate receiving area for dental impression and 23 (74.19%) of the dental technicians continue to wear protective barriers (gloves, mask and apron) during work. In total, 29 (93.55%) of the dental laboratories confirmed, none of their technicians has ever attended any course or training in cross-infection control. Conclusion: The practice of cross-infection control for dental impression in commercial dental laboratories is acceptable. There should be proper guidelines from the regulating body on the protocol of infection control and laboratory waste disposal.
Introduction: Complete loss of teeth, though not life threatening, does have a significant impact on an individual, resulting in functional, psychological, and social limitations, affecting the quality of life and general health. Oral health related quality of life describes the outcomes of oral health conditions and therapy to those conditions. Objective: Geriatric Oral Health Assessment Index questionnaire (GOHAI) consists of 12 items that have an impact on quality of life of the older population, such as functional limitation, psycho-social limitation, and self-medication administered for dental pain. The study aimed to assess the effects of complete edentulousness before prosthodontic rehabilitation using GOHAI. Methods: Descriptive cross-sectional questionnaire study was done among 35 completely edentulous patients prior to prosthodontic rehabilitation using standardised GOHAI questionnaire consisting of 12 items and the twelfth item was eliminated due to its irrelevancy in the study group. Results: The mean age of the participants was 64.86±8.28 years with the mean duration of edentulousness of 4.02±5.4 years. The ability to swallow comfortably had highest mean GOHAI score (2.80±0.47) followed by use of medication to relieve pain and discomfort around the mouth. The least mean GOHAI score was found in trouble biting or chewing any kinds of food, such as firm meat or apples (1.26±0.56). However, the psychosocial impairment due to problems associated with complete edentulousness was less. Conclusion: Complete edentulousness was associated with impairment in physical functions like trouble in biting and chewing, with a need to limit the kinds and amount of food.
