Benign Orofacial Vascular Anomalies: Review of 47 Cases in Enugu, Nigeria.

BACKGROUND: A study of oral vascular anomalies has not been conducted in Nigeria to provide baseline data for comparison with reports in the literature. AIMS: To study the prevalence and distribution of benign orofacial vascular anomalies at a tertiary hospital in Enugu. MATERIALS AND METHODS: This is a 10-year retrospective observational study of consecutive patients with orofacial vascular anomalies, diagnosed by histology. The clinic-pathologic information was obtained from records archived in the department, and descriptive analysis was used to determine the frequency, tables for categorical variables, and a Chi-square test to determine the statistical significance. RESULT: There were 47 cases of benign vascular anomalies out of 897 orofacial lesions giving a prevalence of 5.2%. There were 35.4% (17) male and 64.6% (31) female patients. The mean age in this series was 37.4 ± 19.8 (range: 1 to 76 years). Pyogenic granuloma was the most common vascular lesion 78.7% (37), followed by hemangioma 14.9% (7) and lymphangioma 6.4% (3). The gingiva was the most frequent site of oral occurrence 65.9% (31), especially maxillary gingivae 48.9% (23). The type of orofacial vascular anomalies was significantly associated with the anatomical site of occurrence, P = 0.00. The mean ages for the occurrence of pyogenic granuloma, hemangioma, and lymphangioma were 37.7 ± 18.3, 50.7 ± 16.9 years, and 3.3 ± 3.2 years, respectively. Pain was a frequent occurrence in 36.2% (17) of anomalies. CONCLUSION: Oral vascular anomalies predominantly presented as pyogenic granuloma on the gingivae, while oral hemangioma was observed in adults, and lymphangioma was infrequent.

Oral Pyogenic Granuloma: A Narrative Review.

Pyogenic granuloma (PG) is a benign vascular lesion found predominantly in the oral cavity. Characterized by rapid growth and propensity to bleed, PG presents diagnostic challenges due to its similarity and alarming proliferation. This narrative review synthesizes current knowledge on the epidemiology, etiopathogenesis, clinical manifestations, and management of oral PG, with emphasis on recent advances in diagnostic and therapeutic approaches. The epidemiology of the injury is meticulously analyzed, revealing a higher incidence in women and a wide range of ages of onset. It delves into the etiopathogenesis, highlighting the uncertainty surrounding the exact causal factors, although historical attributions suggest an infectious origin. It exhaustively analyzes the clinical and histopathological aspects of oral PG, offering information on its various presentations and the importance of an accurate diagnosis to guide effective treatment. It details treatment strategies, emphasizing the personalized approach based on individual patient characteristics. This comprehensive review consolidates current knowledge on oral PG, highlighting the need for further research to clarify its pathogenesis and optimize treatment protocols.

A large-cohort study of 2971 cases of epulis: focusing on risk factors associated with recurrence.

BACKGROUND: To analyze the clinicopathological features of different histological subtypes of epulis, and evaluate the risk factors associated with recurrence. MATERIALS AND METHODS: A retrospective study including 2971 patients was performed. The patients' sex, age, location, size, histological subtypes, recurrence information, oral hygiene habits, periodontitis symptoms and smoking history were retrieved from the patient medical records and follow-up information. RESULTS: Among the 2971 cases, focal fibrous hyperplasia (FFH) was the most common lesion (60.92%), followed by peripheral ossifying fibroma (POF) (29.32%), pyogenic granuloma (PG) (8.08%) and peripheral giant cell granuloma (PGCG) (1.68%). The peak incidence of epulis was in the third and fourth decade of life, with a mean age of 45.55 years. Female predominance was found in all types of lesions with a female to male ratio of 1.71:1. PG had the highest recurrence rate (17.18%), followed by POF (12.98%), FFH (9.55%) and PGCG (8.82%). Histological subtypes were significantly correlated with the recurrence of epulis (P = 0.013). Regular supportive periodontal therapy (P = 0.050) had a negative correlation with recurrence, whereas symptoms of periodontitis (P < 0.001) had a positive correlation with the recurrence of epulis. CONCLUSIONS: Controlling the periodontal inflammation and regular supportive periodontal therapy might help reduce the recurrence of epulis.

Gingival and alveolar mucosal reactive hyperplastic lesions: a retrospective clinical and histological study of 996 cases.

BACKGROUND: gingival/alveolar mucosal reactive hyperplastic lesions (GRHL), including fibrous hyperplasia (FH), pyogenic granuloma (PG), peripheral ossifying fibroma (POF) and peripheral giant cell lesion (PGCL), are a common group of oral diseases. The aim of the present study was to access the frequency and distribution of the clinical and histological features of these disorders in a Brazilian population. MATERIAL AND METHODS: all specimens diagnosed as GRHL in three Oral Pathology laboratories were selected for the study. Clinical information was retrieved from the laboratory biopsy forms and hematoxylin and eosin stained histological slides were reviewed for analysis of the histological characteristics. RESULTS: final sample was composed of 996 specimens, including 463 FH (47%), 280 PG (28%), 183 POF (18%) and 70 PGCL (7%). Females were more affected by FH, PG, and POF, and most cases affected adults with mean ages ranging from 40 to 53 years. FH, PG, and POF were more common in the upper gingiva/alveolar mucosa. Most PG, POF and PGCL were pedunculated, in contrast with FH (p<0.001). PG, FH and POF were mostly red or normal mucosal in color, while PGCL were mostly red/purple (p<0.001). PGCL were larger, followed by POF, FH and PG (p<0.001). Some histological features were characteristically found in some conditions, but they were also encountered in other lesions with variable frequencies. CONCLUSIONS: Oral medicine specialists, oral pathologists and periodontists are usually the professionals in contact with patients presenting GRHL and it is of upmost relevance that they should be familiarized with their clinical and histological profile.

Granuloma piógeno oral. Serie de casos / Oral pyogenic granuloma. Case series

RESUMEN El granuloma piógeno es una lesión que se manifiesta en la piel y en la cavidad oral, relacionado con diversas causas, como irritación crónica, trauma y cambios hormonales. Clínicamente se muestra como una lesión hiperplásica altamente vascularizada, con un tamaño de 1-3 cm, de base pedunculada o sésil y de crecimiento lento. Predomina en el sexo femenino y tiende a aparecer, sobre todo, en la encía, con muy pocos casos reportados en zonas edentes, motivo por el que se realizó el reporte de tres casos de granuloma piógeno oral en pacientes femeninas, comprendidas entre 30 y 40 años de edad. Se presentaron lesiones que diferían en cuanto a su localización y apariencia clínica (AU).

ABSTRACT Pyogenic granuloma is a lesion that arises in the skin and oral cavity, related to various causes, such as chronic irritation, trauma and hormonal changes. Clinically it looks like a highly vascularized hyperplastic lesion, sized 1-3 cm, with a pedunculated or sessile base and slow growing. It predominates in the female sex and tends to appear, above all, in the gum, with very few cases reported in edentulous areas; that is why the authors reported three cases of oral pyogenic granuloma in female patients, aged between 30 and 40 years. The lesions differed in their location and clinical appearance (AU).

An analysis of the prevalence of peripheral giant cell granuloma and pyogenic granuloma in relation to a dental implant.

BACKGROUND: The aim of the present investigation was to evaluate the literature recurrence of peripheral giant cell granuloma and pyogenic granuloma associated with dental implants. It's important to know the characteristics present in these lesions and possible effects on the prognosis of dental implants. METHODS: An electronic search without time restrictions was done in the databases: PubMed/Medline. With the keywords "Granuloma" OR "Granuloma, Giant Cell" OR "peripheral giant cell" OR "Granuloma, Pyogenic" AND "Dental implants" OR "Oral implants". RESULTS: After applying the inclusion and exclusion criteria, a total of 20 articles were included, which reported 32 lesions (10 pyogenic granulomas, 21 peripheral giant cell granulomas and one peripheral giant cell granuloma combined with peripheral ossifying fibroma, all associated with implants). According to our review, these lesions are more frequent in males and in the posterior region of the mandible. Both excision and curettage of the lesion, compared to only excision, presented similar recurrences (40%). Explantation of the implant was performed in 41% of cases without additional recurrences. The results are not statistically significant when comparing one lesion to the other in terms of explantation (p = 0.97), recurrence (p = 0.57) or bone loss (p = 0.67). CONCLUSIONS: The main therapeutic approach is tissue excision. The lesions show a high recurrence rate (34.4%), which often requires explantation of the associated implant. This recurrence rate is not affected by curettage after excision.

Oral pyogenic granuloma: An 18-year retrospective clinicopathological and immunohistochemical study.

BACKGROUND: Pyogenic granuloma (PG) is a lesion characterized by the proliferation of blood vessels, commonly affecting the skin and the mouth. We aimed to compare clinical, microscopic, and immunohistochemical features of the two types of oral PG: lobular capillary hemangioma (LCH) and non-LCH (NLCH). METHODS: Epidemiological and clinical data from 2000 to 2018 were collected from the archives of our institution, and histopathological sections of PG were reviewed. Immunohistochemical analyses (CD34, D2-40, SMA, mast cell, and Ki-67) were performed in 34 cases. RESULTS: Sixty-two LCH and 107 non-LCH samples were included. The mean (±SD) age of the patients was 38.59 ± 16.96 years; 55.62% were female; 39.64% of cases occurred in the gingiva, 44% of the nodules were pedunculated, and 13.02% of patients reported a history of trauma. NLCH was more prevalent among older patients than LCH. The most prevalent site of LCH was the lips, while NLCH occurred more in the gingiva (P < 0.05). Epithelial atrophy, microvessels, SMA-positive areas, and Ki-67-positive nuclei were more prevalent in LCH (P < 0.05). CONCLUSIONS: PG accounted for 2.25% of lesions archived in the pathology service and most cases were NLCH. LCH and NLCH exhibited clinicopathological differences in terms of age, site, epithelial atrophy, vascularization, and proliferation rate.

Pattern of distribution of reactive localised hyperplasia of the oral cavity in patients at a tertiary health institution in Nigeria.

BACKGROUND: Reactive localized hyperplastic lesions of the oral cavity (RHLs) are relatively common peripheral lesions which present as a range of clinically similar lesions at dental centers. Diagnosis can be challenging if dentists are unfamiliar with their clinicopathological across various populations. OBJECTIVE: This study reviews the pattern of distribution of RHLs of the oral mucosa in a hospital- the Obafemi Awolowo University Teaching Hospital Complex (OAUTHC), Ile-Ife. MATERIALS AND METHODS: We reviewed 10 years data from the archives of the Department of Oral Maxillofacial Surgery and Oral Pathology, Obafemi Awolowo University, Nigeria. Information on RHLs were extracted and recorded on standardized data forms and analyzed using STATA. RESULTS: The most common lesions were pyogenic granuloma (43.7%) and focal fibrous hyperplasia (39.7%), respectively. RHLs were found to be more frequent in women (66.7%) than men (33.3%). The most common locations of involvement was the gingivae (84.6%), and lesions were more common in the 9-29 year age group and the mean age was 37.7 (±21.1) years. The relationship between age group and reactive lesions was however not statistically significant. CONCLUSION: The major benefit of this study is an improved knowledge of the frequency and distribution of oral reactive lesions in sub-Saharan Africa which may be highly beneficial when establishing a diagnosis and treatment plan in clinical practice.

Prevalence of Oral Mucosal Lesions in a Tertiary Care Dental Hospital of Kathmandu.

INTRODUCTION: Oral mucosa can be affected by a variety of soft tissue lesions and conditions. Benign as well as malignant lesions of oral cavity are common. Squamous cell carcinoma is one of the commonest malignancies. The present retrospective study was undertaken to study the prevalence of various oral mucosal lesions in a tertiary care dental hospital of Kathmandu. METHODS: This retrospective study was carried out in the Department of Oral and Maxillofacial Pathology at Kantipur Dental College and Teaching hospital from January 2015 to January 2017. The study included biopsy specimen from the oral cavity. The parameters included in the study were age, gender, site of the lesion and histopathological diagnosis. The data collected was statistically analyzed. RESULTS: A total of 111 biopsy cases were included in the present study. Out of which, there were 16 (14.4%) cases of non-neoplastic and 16 (14.4%) cases of benign pathology. The oral cavity lesions were commonly seen in age range between 6-74 years where males 59 (53.2%) were mostly affected. The most common site for oral lesion was buccal mucosa 23 (20.7%) and anterior gingiva 23 (20.7%). Total 15 (13.5%) cases of oral squamous cell carcinoma were seen as the predominant malignancy affecting in the vestibular region 8 (7.2%). CONCLUSIONS: The present study shows benign as well as the non-neoplastic lesions were more prevalent in oral mucosa with the buccal mucosa and anterior gingiva as the commonest site of occurrence.

Prevalence and pattern of lobular capillary hemangioma in Eastern Madhya Pradesh, India: A clinicopathological analysis.

BACKGROUND: Lobular capillary hemangioma is a common benign vascular tumor seen in the oral cavity. It occurs in response to various stimuli such as low-grade local irritation, traumatic insult, and hormonal factors or as a response to a wide variety of drugs. MATERIALS AND METHODS: All patients presenting to the Department of Dentistry, Shyam Shah Medical College, Rewa, Madhya Pradesh during July 2014 to June 2016, who were diagnosed by histopathologic confirmation as oral lobular capillary hemangioma (OLCH), were evaluated for the area involved, clinicopathologic presentation, demographic features, and treatment. RESULTS: A total of 94 cases were identified as OLCH by histopathologic confirmation during this period. The lesion occurred most commonly in the age group of 21-30 years. A characteristic female predominance (female: male ratio of 2.24:1) was seen. Anterior maxillary labial gingiva was most frequently involved (34.04%) followed by posterior maxillary buccal gingiva (14.89%). CONCLUSION: The clinicopathologic picture of OLCH found in this study was similar to other studies conducted on same as well different ethnic and geographical populations. Poor oral-dental-hygiene was observed in majority of patients (87.23%) dental health education should be an integral component of imparting oral health care by health providers. Surgical excision as a treatment modality renders good results with low recurrence rate.

Granuloma piógeno de localización atípica: reporte de un caso / Atypical location of a pyogenic granuloma: report of a case

El granuloma piógeno es una lesión que se manifiesta con frecuencia en piel y cavidad oral, está relacionado con diversas causas como irritación crónica, trauma y cambios hormonales. Clínicamente se muestra como una lesión hiperplásica altamente vascularizada de tamaño por lo regularmenor de 2 cm, de base pedunculada o sésil y de crecimiento lento. No tiene predilección por edad o sexo, tiende a aparecer sobre todo en la encía, labios y mucosa bucal, con muy pocos casos reportados en la región lingual, motivo por el que se lleva a cabo el presente reporte de caso, a fin de describir esta lesión en el tercio posterior del dorso delengua en un paciente de 85 años de edad.

Piogenyc granuloma is an injury commonly seen in the skin and oralcavity, it is related to several causes such as chronic irritation, traumaand hormonal changes. Clinically, it is presented as a hyperplasicinjury highly vascular-related, with a size generally no bigger than 2cm pedunculated in base or sessile and slow in growth. Without showingany preferece in age or gender, it tends to appear mainly on the gums,lips and oral mucosae, with very few reported cases in the lingual area.Therefore the hereby report is delivered as means to describe this kindof injury with a very unusual location.

Retrospective analysis of biopsied oral and maxillofacial lesions in South-Western Saudi Arabia.

OBJECTIVES: To report the prevalence and types of biopsied oral and maxillofacial lesions (OMLs) in South-Western (Jazan Province) region, , Kingdom of Saudi Arabia (KSA). Methods: This retrospective study was based on the retrieval of clinicopathological data for a period of 6 years between January 2009 and December 2014. These  data were obtained between October 2014 and June 2015 from the histopathology records of King Fahad Central Hospital, Jazan, KSA, which is the only referral center for biopsy services. Results: Out of the 32149 biopsies received, 714 (2.2%) were OMLs. The age ranged from 0 (neonatal) to 100 years, with a mean age of 46.8±23.4 and a male-to-female ratio of 1:1.3. The tongue was the most common site for OMLs and for malignant neoplasms, in particular. The most common category was malignant neoplasm (38.7%), followed by inflammatory lesions (16.5%). Oral malignancies accounted for 15.8% of all malignancies. Oral squamous cell carcinoma (OSCC) (36.1%) was the most frequent type, followed by pyogenic granuloma and mucocele (7% each). Shammah-associated OSCC and epithelial dysplasia were twice as common in females. Conclusion: The number of non-malignant OMLs was much lower than expected in comparison to oral malignancies. This difference can likely be explained by the fact that the biopsies were taken only when malignancy was suspected. The higher rate of OSCC reported from this region is attributed to shammah usage. This study emphasizes the importance of biopsy services for all OMLs and the prevention of shammah use.

Systemic alterations and their oral manifestations in pregnant women.

The aims of this literature review are: to depict the main oral diseases that are related to pregnancy; to clarify some of the possible systemic mechanisms that are associated with these changes; and to address issues about oral care during pregnancy. A woman's organs undergo various physiological, neurological, and hormonal changes during pregnancy. Such changes occur gradually and are essential for the development of the fetus, providing what is needed for tissue formation and establishment of reserves for uterine and fetal life. In turn, the oral cavity shows some events during this period. Among the changes most frequently cited in the literature are pyogenic granuloma, gingivitis, and periodontitis. The inflammation of the periodontal tissues due to the formation of the biofilm increases dramatically in size and severity during the course of a normal pregnancy, even without changes in the amount of biofilm present. In addition, a decrease in salivary pH is observed in pregnant women and may lead to an increased incidence of dental caries in this period.

Medically uncontrolled conjunctival pyogenic granulomas: correlation between clinical characteristics and histological findings.

BACKGROUND: Conjunctival pyogenic granulomas are commonly seen after ocular surgeries or at an ocular wound site. The aim of this study is to describe a novel histological classification for medically uncontrolled conjunctival pyogenic granulomas (MUCPG), and to explore whether the diversity in clinical features correlates to different histological subtypes of MUCPG. METHODS: This is an observational cross-section case series. We reviewed 46 consecutive patients with conjunctival pyogenic granulomas who did not respond to topical corticosteroids and underwent surgical excision from January 1, 2006 through December 31, 2015. Clinical features and histological findings were presented and analyzed. RESULTS: Ocular surgery, accidental injury, and chalazion were the main predisposing causes of MUCPG. The lesions tended to occur unilaterally on the bulbar conjunctiva. Forty patients (87%) presented an enrichment of inflammatory cells and proliferated capillaries in their pathological sections (inflammatory pattern). Six patients (13%) showed relatively few inflammatory cells and capillaries within fibrous stroma (fibrous pattern). Patients with the inflammatory pattern were older (p = 0.025) and tended to be located in bulbar conjunctiva (p = 0.002). The predisposing causes were also different between two histological subtypes (p = 0.007). CONCLUSIONS: We found the correlation between clinical presentation and histological subtypes in patients with MUCPG, indicating this disease may need a new classification scheme.

Correlation of Age, Sex, and Location With Recurrence of Oral Giant Pyogenic Granuloma After Surgical Excision.

OBJECTIVES: This study was carried out to correlate age and sex of the patient as well as location of the oral giant pyogenic granuloma (PG) with the recurrence rate after surgical excision. METHODS: Seventy-two patients having oral giant PGs were treated by a conservative surgical excision. Information on sex, age, lesion site, and recurrence was collected. Data were reviewed and analyzed to correlate the recurrence rate with sex and age of the patient as well as the location of the lesion. RESULTS: Recurrence of the oral giant PG was occurred in 22.2% of patients. The highest rates of recurrence were observed in the third (33.3%) and fourth (19%) decades of life. The recurrence rate was more common in females (24%) than males (18.2%) and it was predominant in mandibular lesions (25%) than maxillary one (8.3%). CONCLUSIONS: On the basis of their results the authors concluded that recurrence of oral giant PG has an obvious correlation with age and sex of the patient as well as location of the lesion.

Hair and Scalp Disorders in a Tuscan Pediatric Dermatological Outpatient Clinic: A Clinical and Epidemiological Evaluation.

OBJECTIVES: The aim of this study was to evaluate the clinical and epidemiological profile of hair and scalp disorders in children referred to the Pediatric Dermatology Outpatient Clinic. MATERIALS AND METHODS: We performed a retrospective study of children with hair loss problems or scalp diseases who turned to the Pediatric Dermatology Service, Anna Meyer Pediatric Hospital, Florence, Italy, from January 1, 2009, to December 31, 2009. Demographics, personal and familial medical history, laboratory tests, clinical examination, final diagnosis and therapeutic interventions were obtained from the manual chart review. RESULTS: Of the 2,640 children who had access to the Pediatric Dermatology Service, 190 (7.19%) had a hair or scalp disorder. Among the 190 children, 60 (31.57%) presented with nonscarring alopecia, 56 (29.47%) had benign neoplasias, hamartomas or vascular malformations of the scalp, 51 (26.84%) had scalp inflammatory diseases, 14 (7.36%) had scarring alopecia, 5 (2.63%) had infections and 2 (1.05%) had infestation of the scalp. A case of constitutional hypertrichosis (0.52%) and also a case (0.52%) of lamellar ichthyosis were diagnosed. CONCLUSIONS: Our results underline that hair and scalp diseases represent an important percentage of admittances to a dermatological pediatric outpatient clinic. The variety and complexity of the diseases observed in this study included diseases commonly found also in adulthood.

A retrospective analysis of reactive hyperplastic lesions of the oral cavity: study of 1149 cases diagnosed between 2000 and 2011, Chile / Análisis retrospectivo de lesiones reaccionales hiperplásicas en mucosa oral: estudio de 1149 casos diagnosticados entre el 2000–2011 en chile

El objetivo de este estudio fue determinar la frecuencia relativa y distribución de lesiones reaccionales hiperplásicas (LRH) de la mucosa oral, presentes en el registro de biopsias del Servicio de Anatomía Patológica de la Facultad de Odontología, Universidad de Chile. Este estudio de tipo retrospectivo consistió en 1149 biopsias con diagnóstico histopatológico de LRH, entre los años 2000-2011. Las LRH se clasificaron en 5 grupos: Hiperplasia fibrosa (HF), granuloma piogénico (GP), granuloma periférico de células gigantes (GPCG) y fibroma osificante periférico(FOP). Los datos de edad y sexo de los sujetos, y de localización y tipo de lesión, fueron obtenidos del registro de biopsias de cada caso. De las LRH, la lesión más frecuente fue HF (71,1 por ciento), seguido de GP (21,1 por ciento), GPCG (5 por ciento) y FOP (2,9 por ciento) respectivamente. Las biopsias de LRH fueron mas frecuentes en mujeres (70,7 por ciento). El rango etario más afectado fue el de 50 a 59 años (22 por ciento). La localización de mayor frecuencia de LRH fue el maxilar superior (24,7 por ciento), seguida de mejilla (20,6 por ciento), lengua (19,4 por ciento), mandíbula (18,5 por ciento), labio inferior (9,9 por ciento) y labio superior (6,7 por ciento). En este estudio, de las LRH el diagnóstico más prevalente fue FH. El sexo más afectado fue el femenino, el rango etario el de 50 a 59 años y la ubicación más frecuente, maxilar superior. Estos resultados en general son concordantes con lo descrito en otros países.

The aim of this study was to determine the relative frequency and distribution of reactive hyperplastic lesions (RHL) of the oral mucosa at the Oral Pathology Institute of the School of Dentistry at the University of Chile. This was a retrospective study of 1149 biopsies with histopathological diagnosis of RHL, performed between 2000 and 2011. The RHL were classified in 4 groups: fibrous hyperplasia (FH), pyogenic granuloma (PG), peripheral giant-cell granuloma (PGCG) and peripheral ossifying fibroma (POF). Results: the most frequent RHL was FH (71. 1%), followed by PG (21.1%), PGCG (5 %) and POF (2.9%). RHLs were more frequent in women (70.7%). The most highly affected age group was the 50- to 59-year-olds (22%). The most frequent location for RHL was maxilla (24.7%), followed by cheek (20.6%), tongue (19.4%) and jaw (18.5%). The most prevalent RHL diagnosis was FH. Themost frequently affected sex was female, the most frequent agerange was 50-59 years, and the most frequent location, maxilla.

Oral granuloma gravidarum: a retrospective study of 41 cases in Southern Brazil.

Granuloma gravidarum (GG) is an inflammatory lesion, which develops in the oral mucosa of pregnant women in response to chronic low-grade irritants, under the influence of hormonal factors. Objective To characterize GG clinically by means of a retrospective study of the cases of the Oral Medicine Division, São Lucas Hospital, Brazil. Material and Methods Cases of GG diagnosed between 1980 and 2012 were analyzed. Data were obtained referring to the age of the patients, lesion location, clinical features, as well as the presence of local irritants. The gestation period in which the lesion developed was also investigated. Results Forty-one cases of GG were found. The lesions developed predominantly in the third trimester of pregnancy (51.22%) and the mean age of the patients was 28 years. Most GG was found in the gingiva (73.17%), was reddish color and had a mean diameter of 1.5 cm. Local irritants were involved in 75.6% of the cases. Conclusions The hormonal conditions of pregnancy can have an impact on the oral cavity, predisposing the patient to inflammatory lesions such as GG.

Biopsied lesions of the gingiva in a southern Indian population - a retrospective study.

PURPOSE: To retrospectively analyse the frequency and distribution of various biopsied lesions of the gingiva among patients attending a dental teaching institution in Karnataka state in India. MATERIALS AND METHODS: Data collected from 153 gingival biopsies referred to the Department of Oral Pathology, Yenepoya Dental College in Mangalore, Karnataka state, India during a 5-year period from 2004-2008 were utilised for the purpose of this study. Lesions were categorised by their type and analysed for age, sex and location. RESULTS: Non-neoplastic lesions accounted for 51% while neoplastic and potentially malignant lesions accounted for 49% of the lesions. The most common non-neoplastic lesion was pyogenic granuloma (42.3%), the most common benign neoplasm was fibroma (34.5%) and the most common malignant lesion was squamous cell carcinoma (82.6%). Among all the lesions, the most common was squamous cell carcinoma (24.8% of all the lesions). CONCLUSIONS: Unlike in previous studies, squamous cell carcinoma was the most common gingival lesion. The proportion of malignant and potentially malignant lesions was also higher among subjects in the present study than in other populations. Hence, public oral health programmes need to be formulated to better tackle the burden of these diseases.
