ABSTRACT

The aim of this study was to investigate the ability of serrapeptase to reduce postoperative swelling, pain and trismus after third molar surgery. Twenty-four healthy individuals with symmetrically impacted mandibular third molars underwent surgical removal in a prospective, intra-individual, randomized, double-blind, cross-over study. Teeth were removed in 2 sessions by the same surgeon. At each session, one third molar was removed under local anaesthesia via a buccal osteotomy. All patients received a combination of either serrapeptase 5mg or placebo tablets and 1000 mg paracetamol tablets at either the 1st or 2nd operation in accordance with the randomization plan. Cheek thickness, pain and interincisal distance were measured preoperatively, and on the 1st, 2nd, 3rd and 7th postoperative days. Cheek thickness and maximum interincisal distance were measured using calipers. Pain intensity was assessed clinically using a numeric scale. There was a significant reduction in the extent of cheek swelling and pain intensity in the serrapeptase group at the 2nd, 3rd and 7th postoperative days (P<0.05), but no significant difference in mean maximal interincisal distance was found between the 2 groups (P>0.05).

ABSTRACT

The aim of this study was to report the results of long-term clinical and radiological follow up of the surgical management of central giant cell granuloma of the maxilla. A retrospective analysis was conducted on 12 patients--5 male and 7 female whose ages ranged from 9 to 41 years, with central giant cell granuloma of the maxilla treated between 1991 and 2000. The anterior maxilla was involved in five cases, seven cases were in the posterior region, and none crossed the midline. Four patients were asymptomatic and eight patients presented with pain, mobility of teeth, and rapidly enlarging facial swelling. Radiographically, all lesions were radiolucent; 58.3% were unilocular, and the borders were well-defined in 33.3%. Roots were commonly displaced by the lesion, but no root resorption was observed. Cortical perforation was seen clinically and on CT scan in four patients. All cases were treated with thorough curettage until healthy bone was encountered. In cases with cortical perforation the affected buccal and/or palatal mucosa was excised. When the maxillary sinus was affected or the lesion was bulging into the nose, the nasal mucosa was also removed. All patients were reviewed annually for a follow-up period of 2-9 years; the condition recurred in two patients. It is concluded that thorough curettage is a satisfactory method for the treatment of non-aggressive and aggressive central giant cell granuloma of the maxilla, with a low recurrence rate and favorable postoperative outcome.

ABSTRACT

This study evaluates the types and distribution of oral and maxillofacial tumours in north Jordanian children and adolescents. The records of the Department of Pathology at Jordan University of Science & Technology, during the period 1991-2000, were reviewed for patients younger than 19 years with oral and maxillofacial tumours. The tumours were analysed for age, sex, site and type. Out of all maxillofacial tumours, 23% occurred in children and adolescents, of these 10% were malignant and 90% were benign. 73% of the latter were soft tissue tumours and 17% were jaw tumours (58% odontogenic and 42% non-odontogenic). The most common benign soft tissue and jaw tumours were haemangioma and odontoma, respectively. 58% of malignant tumours were sarcomas and 42% were carcinomas. The mean age was 11 years with a female to male ratio of 1:1.2. The intraoral and extraoral sites most commonly affected by benign soft tissue tumours were the lower lip and face, respectively. While the total number of benign jaw tumours was slightly larger in the maxilla than the mandible, odontogenic tumours were more in the maxilla, and nonodontogenic tumours were more in the mandible. Differences found in this study between Jordanian children and adolescents and those from other countries may be attributable to genetic and geographic differences. The majority of benign tumours in the young are probably developmental rather than true neoplasms.

ABSTRACT

AIM: The purpose of this study was to determine the prevalence of dilaceration in a sample of Jordanian dental patients. METHODOLOGY: The data were collected from examination of radiographs from a random sample of periapical films. In all, 4655 teeth from 814 dental records at the Faculty of Dentistry, Irbid, Jordan were evaluated. The films were viewed using a magnifying lens and an X-ray viewer. A tooth was recorded as having a dilaceration towards the mesial or distal direction if there was a 90 angle or greater along its long axis using a small ruler aligned along the pulp of the tooth. Dilacerated roots towards the buccal or lingual directions were determined by evaluating the appearance of a round opaque area with a dark shadow in its central region, cast by the apical foramen in which the root canal gave a 'bulls-eye' appearance. RESULTS: Dilacerations were recorded in 3.78% of the teeth examined. Mandibular third molar teeth were the most commonly affected (19.2%) followed by mandibular first molars (5.6%). The maxillary anterior teeth and mandibular incisors were least affected exhibiting dilaceration in approximately 1% of teeth. Two-thirds of the dilacerations were in the mandible and approximately 5% were in anterior teeth. CONCLUSION: Dilaceration is not common, but it is an important dental anomaly that affects all teeth. Recognizing the condition will facilitate endodontic, orthodontic and surgical treatment.

ABSTRACT

The objective of this investigation was to study the effectiveness of expanded polytetrafluoroethylene (e-PTFE) membranes for enhancement of bone ingrowth through subperiosteally implanted collagen/HA composite blocks. Twelve rabbits aged 12-15 months served as the experimental animals in this study. Two compressed Collagen/HA composite blocks in the shape of two attached cylinders of different diameters were inserted into two defects of each rabbit calvarium, the smaller cylinder being intrabony, the larger subperiosteal in location. One of the two implants was covered with non-resorbable e-PTFE membrane. The other implant was left uncovered. Specimens were obtained at 4, 8, and 12 weeks. While the implant specimens on the membrane side showed progressive bone formation between and around HA particles at the subperiosteal extrabony locations, the HA particles on the non-membrane side were surrounded and separated by dense fibrous tissue. At intraosseous sites, HA particles were surrounded by new bone throughout the defect on the membrane side, but new bone formation occurred only along the periphery on the non-membrane side. It appears that guided tissue regeneration may be used to enhance new bone formation around and between subperiosteally implanted HA particles.

ABSTRACT

OBJECTIVES: In recent years, injection of pure glycerol has been used successfully for the treatment of trigeminal neuralgia. However, the mode of action of this therapy remains unclear. The present experiment was undertaken to examine histologically the morphologic changes produced by extraneural injections of pure glycerol into the dog mental nerve. STUDY DESIGN: Under direct vision, glycerol was injected extraneurally into the mental foramen on one side of the lower jaw of each of nine dogs. Physiologic saline solution was the control on the contralateral side of each animal. Animals were killed at 1, 3, and 7 days after the application of glycerol, and the mental nerve specimens were examined by light microscopy. RESULTS: Results showed that extraneural application of pure glycerol in the vicinity of the dog mental nerve is not associated with structural changes. No signs of nerve degeneration or other morphologic changes were observed for any of the experimental and control specimens in any of the time intervals studied. CONCLUSIONS: It can be concluded that despite the encouraging clinical results related to extraneural application of pure glycerol for treatment of trigeminal neuralgia, glycerol produces its effect without inducing any morphologic or destructive changes in the peripheral nerve. A probable explanation of the temporary clinical effectiveness of glycerol in relieving trigeminal neuralgia is discussed.

ABSTRACT

To overcome the difficulties of studying wounding and wound repopulation in monolayer systems, a 3-dimensional model of wound repopulation has been developed which allows the in vitro investigation of fibroblast migration in response to experimental wounding. This model was utilized to determine whether fibroblasts derived from sites which demonstrate preferential healing (child and oral mucosal fibroblasts) possessed an increased ability to repopulate experimental wounds when compared to adult dermal fibroblasts. Fibroblasts were established from specimens derived from healthy donors undergoing minor elective surgery. Standard wounds were created in fibroblast populated collagen lattices (FPCLs) which were then overlaid upon an extracellular wound matrix. Fibroblast repopulation of the wounds was studied over 12 days using light- and scanning electron microscopy and quantified using computerized image analysis. Wound repopulation by fibroblasts derived from child donors (n = 3) was significantly (P < 0.001) more rapid than their adult tissue-matched counterparts (n = 3). Wound repopulation by oral mucosal fibroblasts (n = 3) was significantly greater than that exhibited by age-matched dermal fibroblasts (n = 3; P < 0.05). These differences were not reflected in differences in DNA synthesis (P > 0.5) or cell number (P > 0.5) within similar attached FPCL systems. These findings further support the concept of a gradual transition from the fetal to adult phenotype in wound healing. The potential applications of the model are discussed.

ABSTRACT

Intra-oral wounds, like wounds in children, demonstrate privileged healing when compared with adult wounds at extra-oral sites. This study investigated whether this preferential healing is related to an increased ability of oral mucosal fibroblasts to reorganize extracellular matrix (ECM) when compared with their dermal counterparts. ECM reorganization was investigated by means of a fibroblast-populated collagen lattice (FPCL) system. The effect of donor age was also investigated in this system. Differences in ECM reorganization and FPCL contraction were evident: FPCL contraction was more rapid by oral mucosal fibroblasts than dermal fibroblasts (p < 0.01). FPCL contraction was also greater in child (donor < 10 years) than adult (donor > 18 years) oral mucosal fibroblasts (p < 0.01). These differences were not related to phenotypic differences in cell viability (p > 0.5), DNA synthesis (p > 0.05), and cell number (p > 0.5) within the FPCLs, or cellular attachment to collagen (p > 0.07). FPCL contraction was not stimulated by the addition of conditioned medium from oral mucosal or dermal fibroblasts (p > 0.05). These data show that the significantly increased ability of oral mucosal fibroblasts to reorganize ECM in vitro, when compared with dermal fibroblasts, represents a distinct phenotypic contractile difference, rather than differences in their production of soluble mediators or cell attachment to ECM.

ABSTRACT

The oral and dental abnormalities associated with a distinct variety of severe short-limb dwarfism are described. The patient, a 9-year-old Arab boy, had delayed development and eruption of teeth, severe oligodontia of permanent dentition, hypodontia, microdontia, supplemental incisor, enamel hypoplasia of primary teeth, doubled and abnormal frenal attachments, bifid uvula, hypoplastic maxilla, and malocclusion. Clinical and radiographic examinations revealed asymmetric dysplasia and anaplasia of long bones, craniofacial dysmorphia, prominent forehead, budlike fingers and bulbous toes, dysplastic nails, severe hearing loss, and reduced joint mobility. These features resemble, in general, those characteristic of Grebe chondrodysplasia, an extremely rare ill-defined syndrome that is inherited as an autosomal-recessive disorder.

ABSTRACT

This study investigated the effect of clinical concentrations of alcohol on fibroblast function (proliferation and ECM synthesis) in vitro. Basal and TGF-beta-induced collagen synthesis was assayed in confluent cultures in serum-free medium at 48 h with a commercial collagen assay system. At concentrations of alcohol > 5%, fibroblast proliferation was significantly inhibited. Although noninhibitory, subclinical concentrations of alcohol failed to inhibit basal collagen synthesis (P > 0.1), they significantly decreased TGF-beta-induced collagen synthesis (P < 0.03). These data support the notion that the local, as well as the systemic, effects of alcohol are important in mediating delayed healing in alcoholic patients.

ABSTRACT

The use of collagen biomaterials in various types, structures and forms to aid in wound healing and in reconstructive surgery has been reported in several occasions in the literature. This paper evaluates the biocompatibility and effectiveness of a modified bovine type I collagen membrane as a graft material in experimental oral wounds in dogs. 2.5 x 2.5 cm wounds were prepared bilaterally in the labial mucosa of nine dogs. Bovine type I atelopeptide reconstituted collagen membrane was placed over the surgery site on one side of the labial mucosa. The contralateral sides served as controls. Clinical and histopathologic evaluation were done at 1, 2 and 3 weeks post-operatively, comparing the experimental side with the control side. Results demonstrated an improved rate of wound healing on the experimental side. The collagen membrane had a topical hemostatic effect at the time of its application and did not cause any adverse reaction post-operatively. It is concluded that the modified collagen membrane used in this study is biologically acceptable to the oral mucosa and is, from the clinical point of view, an excellent wound graft material. The clinical utilization of these collagen sheets offers exciting applications in the field of oral surgery.

ABSTRACT

A panoramic radiographic study was carried out on 404 dentate Saudi Arabians, to locate positions of the mental foramen. Results show that 83.7% of the mental foramen locations occurred in the interdental space between the mandibular premolars and apical to the mandibular second premolar. 9.35% occurred posterior to the mandibular second premolar, and 6.95% occurred apical/anterior to the mandibular first premolar. In female Saudis, the most common location of the mental foramen was apical to the mandibular second premolar (45.9%), while the most common location in male Saudis was the interdental space between the mandibular premolars (45.5%). Asymmetry of the mental foramen location, which was observed in 15.6% of the cases, was observed more often in males (17.9%) than in females (12.3%).

ABSTRACT

The main aims of this study were, first, to estimate the need for periodontal care among adult residents of Saudi Arabia using the community periodontal index of treatment need (CPITN) and, second, to quantify the relationship between the frequency of using the 'Miswak' and the need for periodontal care. The Miswak is a stick made from the roots of the Arak tree (Salvadora persica) and is used for oral hygiene purposes by many cultures. A total sample of 480 adults aged 35 to 44 years and 65 years and older from the cities of Mecca and Jeddah was included in the study. The findings indicate that the level of need for periodontal care in the sample chosen is low when compared with the findings of similar studies undertaken in other countries. The frequent use of the 'Miswak' was associated with a lower need for treatment.

ABSTRACT

A total of 1400 Saudi Arabian children in age groups 6-12 and 15 yr in private and public schools were examined for dental caries and treatment need in the cities of Jeddah (less than 0.30 ppm fluoride in drinking water), Rabagh (0.77 ppm F-) and Mecca (2.47 ppm F-). The mean dmft in 6-yr-olds in private schools in Jeddah was 2.9 compared with 6.3 in public schools (P less than 0.001). The d component accounted for 65% of the total dmft in private schools and 76% in public schools in Jeddah. The mean dmft values in private and public schools in Rabagh were 1.5 and 2.8 respectively and 2.7 and 2.8 in Mecca; the d component accounted for approximately 65% in all groups. The figures for permanent teeth in 12- and 15-yr-olds show similar trends with caries levels being the highest in public schools in Jeddah; approximately 60% of the total DMFT was attributable to the D component in both school types in all three cities. Most of the treatment required in all three cities comprised one- or two-surface fillings. The need for treatment was significantly higher in public schools.

ABSTRACT

Six hundred forty-two impacted third molars were surgically removed in 412 patients. Before surgery, each patient was assessed clinically and radiographically, and the reason for the removal of each tooth was specifically recorded. One hundred eighty-two of the impacted teeth were removed for prophylactic reasons and 460 for therapeutic reasons. As much as possible, standardization of the operating procedure and environment, and of the preoperative and postoperative regimens was observed. After surgery, each case was followed to determine the absence or presence of signs and symptoms of alveolar osteitis. It was found that several factors seem to contribute to the development of alveolar osteitis; however, the most significant related finding was that the reason for the extraction, that is, whether the extraction was undertaken for therapeutic or prophylactic reasons.

ABSTRACT

Children aged 6, 12 and 15 years were examined for dental caries in three cities in Saudi Arabia, with varying levels of naturally occurring fluoride in the drinking water; Jeddah (less than 0.3 ppm), Rabagh (0.8 ppm) and Mecca (2.5 ppm). For each age group, caries levels were considerably higher in Jeddah than in Rabagh or Mecca. Occlusal surfaces were most frequently affected. Children attending public schools experienced a considerably higher caries prevalence than those attending private schools. All age groups had high levels of untreated dental decay. Preliminary results indicate that residents of Mecca exercise unacceptable levels of dental fluorosis.

ABSTRACT

In 1987, the first major dental epidemiological study was carried out in the Kingdom of Saudi Arabia, with the help and cooperation of the WHO Collaborating Centre for Oral Health Services Research, University Dental School, Cork, Ireland. As part of the project, the 15-year-old age group underwent an interview survey in order to ascertain if oral health attitudes and behaviour were related to oral health outcomes, as measured by the mean DMFT for the group. In common with the findings of similar studies in other countries, including Ireland, little or no correlation between the sociological variables and oral health outcomes was apparent. Such findings, however, simply highlight the unreliability of cross-sectional designs when attempting to isolate a relationship between a cumulative condition, such as dental caries, and parameters which clearly change with time. The differences found in the oral health behaviour of the Saudi Arabian and Irish 15-year-old children is particularly noticeable in respect of the frequency of intake of sweet foods and drinks.
