General complications in patients wearing polymethylmethacrylate heat cure acrylic resin partial removable dental prostheses

Objectives of this study was to determine the frequency of general complications in patients wearing polymethylmethacrylate heat cure acrylic resin partial removable dental prostheses. This descriptive study was conducted during July 2013 to June 2014 at dental outpatient department of Liaquat Uni-versity of Medical and Health Sciences Pakistan. Data relating to 110 patients were collected using a structured proforma, by methods of patient's interview, clinical and radiographic examination. Data related to age, gender, location of prosthesis in the dental arch and various complications were recorded. Majority of patients were male with age from 21 to 60 years. Most of complications occurred in maxillary arch especially on right site of the arch. The most prevailing complications in general in this study were loss of retention [56%] mucosal changes [35%], loss of support [31%], discomfort/pain [29%] and loss of stability [26%]. On the other hand the least prevalent complications were speech problem [16%], appearance problems [8%] and only 4% of patients were not satisfied with design of prosthesis. Majority of complications were related to retention, support and loss of stability after wearing prosthesis, therefore correct techniques and material in terms of raising and framing the prosthesis must be implied as it will prevent the patient from many complications

Assessment of patients wearing auto polymerized acrylic resin fixed partial dentures

This descriptive study was carried out at dental out-patient department of Liaquat medical University Hospital Hyderabad from January 2013 to December 2013. Thirty-five patients wearing auto polymerized [self-cured] fixed partial dentures provided by unqualified and qualified dental practitioners were assessed. Condition of oral health was evaluated on the basis of proper history and clinical examination. Prosthesis condition was also assessed. Oral health of underlying soft and hard tissues was carefully evaluated after removing the prosthesis with the help of slow speed hand piece without jeopardizing oral tissues. It was evident in this study that fixed partial dentures made from auto polymerized [self cure] acrylic resins had adversely affected the oral tissues compelling the patients to visit the qualified dentist for proper treatment of their problems

Assessment of the interappointment pain by using two different intracanal medicaments

The objective of this study was to assess the interappointment pain by using two different intracanal medicaments. Comparative study in the department of operative dentistry, Liaquat Medical University Hospital Hyderabad was carried out. 60 teeth either anterior or posterior of male and female patients of 14 to 60 years age diagnosed for root canal treatment were included. Following the routine access cavity preparation, canals were located with endodontic explorer. Working length was taken with 15# k-file, and then instrumentation was performed with proTaper hand files and shaping by the crown down technique along with irrigation by using Milton's [l%Naocl] solution. Canals were dried with paper points and Ledermix paste in Group I and Calcium hydroxide in Group II patients were inserted in random sequence. The patients were recalled, to record the degree of pain on the next day, third day and one week and for clinical evaluation and obturation if the tooth was asymptomatic. Out of 60 cases, 33[55%] were male and 27[45%] were female. Post operative next day, mild pain was observed in 25% [15/60] patients and moderate pain in 20% [12/60] while severe pain in 13.3% [8/60] patients. Similarly on third day, mild pain was observed in 3.3% [2/60] only. While after one week mild pain was found in only 1.6% [1/60] case. Severity of pain was significantly low in group I than group II [p=0.999] after one week. Treatment with Ledermix was significantly better than with Calcium hydroxide in controlling severity of interappointment pain

Functional assessment of removable complete dentures

The objective of this study was to evaluate the clinical quality of old removable complete dentures and to find out patient satisfaction. It was carried out from July 2011 to June 2012. It was case series descriptive study. Data relating to 72 patients wearing complete dentures were collected using structured eight categories, four point scale Proforma. Detailed patient history, clinical and prosthesis examination were undertaken. Data related to age, gender, fitting place and complete denture post-fitting duration were also recorded. Male to female patient's ratio was 2.2:1. Forty one [57%] complete dentures wearers had got their dentures made from public hospitals. Majority [42%] of evaluated complete dentures were not older than five years. Patients told us about good retention in 27 [37.5%] of maxillary and fair retention in 34 [47.2%] of mandibular complete dentures. Good mastication was reported by 40 patients [55.5%] and good esthetics by 34 [47.2%]. Sixty three [87.5%] patients complained about pain in their maxillary dentures and 54[75%] in mandibular dentures. Good stability was reported by 31 [43%] of mandibular dentures and 37 [51.3%] of maxiliary dentures. Good occlusion was seen in 37 [51.3%], oral hygiene in 45 [62.5%] and prostheses hygiene in 39 [54.1%]. It was concluded that retention and stability was good in maxillary dentures while fair in mandibular dentures. Majority of the patients showed poor oral and prosthesis hygiene. Pain was the most common complaint of these complete denture wear

Analysis of maxillofacial fractures in patients treated at liaquat medical university hospital, hyderabad

The objective of the current study was to investigate the frequency, gender and site involvement and etiology of'maxillofacial fractures in patients seen at Liaquat Medical University, Hyderabad. Data of 520patients who were hospitalized for treatment of maxillo facial fractures over a one year time period from June 2010 up to may 2011 were collected. Study design was descriptive. Male to Female ratio was approximately 4:1. Road Traffic Accidents were found to be the most frequent 415 [79%] cause of maxillo facial fractures. Maxillofacial fracture in Male 402 [77.3%] and female 118 [22.9%] and mandible fractures 315 [60%] and midface fractures 205 [40%] were found. The differential sidewise distribution of fractures revealed that parasympasis fracture was the most frequent region 215[68%] in fractures involving mandible. Furthermore, analysis of the midface fractures indicated that zygoma fractures constituted the biggest group 130[63%] while orbit fractures [orbit's floor and walls] were in the second place 15 [7%]. Fracture maxilla 75 [36%] and Le fort II and III were the least common 10[4.8%] fracture of the midface. The relatively high incidence of injuries resulting from road traffic accidents indicates the necessity to support legislation aimed to prevent road traffic crashes and thus to reduce maxillofacial injuries among children and adults

Biofilm formation and isolation of Staphylococcus aureus from blood cultures of dental patients undergoing oral surgical procedures

The objective of this study was the detection and separation of S. aureus from blood cultures of patients undergoing oral surgical procedures. Antibiotic sensitivity pattern and biofilm formation of S. aureus were also performed. Total 250 patients undergoing oral surgical procedures were selected for bacteriological examination. 5ml of Blood sample was collected in blood culture bottles containing tryptone soya broth. Blood sample was incubated at 37[degree sign] C for 7 days and after incubation subculturing was done on appropriate Media. The plates were then incubated at 37[degree sign]C aerobically for 24 hours, after which isolated colonies were obtained. S.aureus was identified by Gram staining, colony morphology, pigment production, catalase, coagulase and often biochemical tests. Antibiotic susceptibility was performed by disc diffusion technique on isosensitivity agar. Strains of S.aureus were used for biofilm formation by simple tubemethod. With the help of spectrophotometer at 570 nm optical density was measured. S.aureus [ATTC2523] was analyzed for biofilm production. Bacterial isolates in descending order were S.aureus 56%, E.coli 25%, Pseudomonas spp. 13%, S.typhi 4%and Shigella spp2%. S.aureus was resistant to different antibiotics. Biofilm production of S.aureus was detected in 16.17%of the S.aureus and mostly in association with antibiotic resistant bacteria. S.aureus was the predominant group of bacteria isolated from blood cultures of dental patients. Increased antibiotic resistance of S.aureus may be due to biofilm production resulting in persistent dental infections

Concepts, techniques and materials used for complete denture impressions by dental house officers

To report data relating to concepts, techniques and materials used by dental house-officers of local dental institutes. With the use of a questionnaire, data relating to concepts, techniques and material used for edentulous impressions were collected from 140 house officers of 10 local dental institutes of these, 121 I house officers retuned the completed questionnaires, yielding a response rate of 86.4%. 96.7% followed the 2-step impression concept of preliminary and final impression. Some 71.9% preferred impression compound only as preliminary impression material. 94.2% used special trays for secondary impressions. Some 43.8% were making them in self-curing denture-base acrylic resin. Border-molding, prior to final impression was preferred by 95.9%, out of which 86.8% were using low fusing impression compound. Vent-holes to allow escape of excess impression material were incorporated by 40.5%, of which 38.0% favored two or more vent-holes. Some 95.9% used zinc-oxide-eugenol alone as the final impression material. Recording of the reline-impression using the open-mouth technique at trial-stage, was preferred by 63.6%. Very few knew about the special impression techniques of functional, sectional, admix, window or plaster-stent impression. Statistical analyses of the data, using chi-square test showed insignificant association between the responses from the graduates working in the public sector and private sector dental institutions. Concerns and issues regarding the non-use of latest impression materials and techniques related to complete denture impressions and a lack of understanding of the related concepts of participants were observed. Strategies for rectification of these are emphasized

Dentists experiences, practices and understanding of some design statements regarding mandibular kennedy class I removable partial dentures

Mandibular Kennedy class I situation being substantial and its restoration need with removable partial dentures [RPDs], necessitates practitioners to be knowledgeable and skillful in the clinical, biological and technical aspects. It is aimed to report clinical experiences and practices with RPDs of some dentists and their understanding of some statements pertaining to the design of these RPDs. Comparative, PMDC Registered dentists in NWFP. A self-administered structured Performa documenting personal and RPD practice related information and responses to some conceptual statements pertaining to a standardized mandibular Kennedy Class I RPD was used to collect data. Data were collected, by either direct personal contact or through mail, from 120 dentists divided into 4 groups on the basis of their professional educational and practice experience level. There were wide variations in responses of dentists regarding the extent of their provision of RPDs and specifically of mandibular Kennedy Class I RPD to patients, A substantial number of dentists [77 97%] had never reappraised their RPD making skills. Not doing jaw cast surveying and delegating the RPD design to dental technician was noted in cases of some 67 - 93% and 20 - 43% respectively. Selection of inappropriate design statements pertaining to the test situation regarding the various aspects of RPD designing was also made by many dentists in the various groups. Participants having relatively fresh entry into clinical dental practice proved more knowledgeable by responding appropriately in larger numbers. Mostly within group and between-group variations were statistically insignificant. Knowledge of the participating dentists in all the 4 groups was poor regarding the understanding of the concepts related to RPD design. However, relatively younger dentists proved better than the others

Some aspects of post-fitting clinical complications in metal-ceramic crowns

Metal-ceramic full-coverage crowns [MCFCs] are the most commonly used coronal restoration in this country. However, locally relevant treatment outcome data regarding these is not available. The objective of this study was to report the distribution and levels of biological and technical complications in MCFCs in relation to arch, location in arches and place of provision / setting. As part of a large study, spanning between February 2007 and Jan 2008, data relating to 121 patients having complications with their levels in MCFCs were recorded. A structured proforma, patient`s interview and clinical and radiographic examinations were the methods used. Wi -an age of participants [33.2 years +/- 11.3 [SD]], males outnumbered females [1.42:1]. Complication occurred in younger patients [21 30 years]. The MCFCs [N =121] were: hospital-fitted [59%], privy - fitted [31.4%] and unqualified personal [10%]. Hospital-fitted MCFCs had 58.1% of the 179 noted coim Is as compared to 34% in private-practice-fitted and 8.4% in those made by unqualified personal. Irresp e of the fitting place, 36% of the complications were in those fitted just 1-year earlier with another 45.0% m -mose not older than 5-years. Complications [19%] were in those MCFCs that were older than 5-years. The noted compplication-events were: de-cementation [24%], peri-apical problems [23%], abutment fracture [13%], caries periodontal-problems [11.2%], esthetic problems [7.0%], artificial crown-fractures [7%], and occlus, [3.4%] withstanding the individual differing proportions and their levels, the distribution is levels of we 179 complication-events was: Level-1 [39.1%], Level-2 [50.3%] and Level- 3 [11%]. Irrespective of their providers or fitting-places as mentioned in this study, MCFCs showed very poor survival data. Strategies for improving the situation are suggested

Pattern of oral squamous cell carcinoma - a study

The study was carried out on a total of 312 biopsy proved patients of oral squamous cell carcinoma over a period of 3 years i.e., from 1[st] January 2004 to 31[st] December 2006 in Oral and Maxillofacial Surgery Unit of Khyber College of Dentistry, Peshawar. The aim of the study was to evaluate different patterns of oral squamous cell carcinoma in the North West Frontier Province. Amongst these 312 patients 214 were males [68.59%] and 98 [31.41%] were females. Male to female ratio was 2.18:1. The age range was from 11 years to 77years, with the mean age of 58.8 years; SD + 12.69. While the most commonly involved age group was 7[th] decade of life [35.57%] followed by 6th and 8th decade [28.20%] and [15.38%] respectively Mandibular left gingivolabial sulcus was the most commonly involved site i.e., 41.34%., followed by mandibular right gingivolabial sulcus [18.2 7%]. The most common histological grade of the tumour was G1 i.e., well differentiated Squamous Cell Carcinoma [74.68%] followed by G2 i.e., moderately differentiated [21.15%] and G3 i.e., poorly differentiated oral squamous cell carcinoma [4.16%]. 84% of patients had a positive history of Niswar dipping

Reasons and problems in dislodged metal ceramic fixed partial dentures presented for recementation by patients

To report reasons and problems seen in dislodged metal ceramic fixed partial dentures [FPDs], presented for re-cementation at the Department of Prosthodontics, Khyber College of Dentistry Peshawar, Pakistan. Using a structured proforma, over a period of one year [Oct: 2005-Sep: 2006], data relating to 46 dislodged FPDs of patients were recorded. These included a history of placement of FPD, reasons for consultation and habits as well as age, gender and other social demographic data. Detailed oral examination, as well as examination of the dislodged FPDs was carried out to record information relating to arch, site, number of units, pontics and retainers. The reasons of dislodgement and length of FPD in service were also ascertained. The proportions of dislodged FPDs were 60.8% in maxillary and 39.1% in the mandibular arch. Majority of FPDs [60.8%] were dislodged in the posterior side, some 30.4% of dislodged FPDs had remained in service for less than one year, where 30.4% had been in service from one to two years and 39.1% for more than two years. The proportions of FPDs that dislodged during normal chewing function were 56.5% as compared to 43.5% that dislodged either as a result of trauma, mouth cleaning or need for endo treatment of abutments. More than one reason/problem was seen in each case of dislodged FPDs in the form of defective margin in 34 cases, unsatisfactory oral hygiene in 30 cases and over-tapered preparation in 28 cases. The numbers and severity of problems seen were more in the dislodged FPDs that had rendered a service life more than two years. Within the limitations of this study, it can concluded that irrespective of the reasons and problems, maxillary FPDs would have a greater tendency for dislodgement and that defective margins, over-tapered preparations and unsatisfactory oral hygiene were the predominant reasons for FPD dislodgement

Obturator prostheses for the rehabilitation of congenital and acquired maxillary defects: treatment report of four cases

Cleft lip and cleft palate are common congenital deformities. The consequent oral deformity though not usually fatal, presents a great deal of personal, social, functional, and psychological morbidity. Defects because of tumor resection also result in high level of morbidity with significant psychological and functional implications for patients, including difficulty to masticate, swallow and speak. The purpose of this clinical writing is to present treatment details, benefits and applicability of appropriate maxillofacial prosthetic rehabilitation in patients with congenital and acquired defects. Treatment reports of four patients, three with congenital cleft palate and one with surgical defect are presented. These cases are of interest in aspect of highlighting the generally observed neglect and ignorance of parents and lack of coordination among members of the interdisciplinary team involved in the total and timely rendered rehabilitation services that leaves the prosthodontist as well as the patients to provide and receive compromised therapeutic approaches at the end. This article will thus in addition to presenting some treatment approaches, also provide guidelines for the effective rehabilitation of patients with maxillopalatal defects by all involved as members of the interdisciplinary team
